As shown in fig. 1-12, the embodiment of the present invention discloses a lock, which includes a lock body 200, a bolt 300, and a rolling part 400, and of course, the lock further includes a buckle plate 100, a lock cylinder, and a front plate, and for the sake of brevity, they are not described one by one here.

The lock body 200 may also be made of metal or other materials, and the mounting groove 212 and the bolt through hole 211 may be integrally formed with the lock body 200 by die casting, or may be formed by drilling after the lock body 200 is molded; the bolt through hole 211 is an opening hole formed through the lock body 200, so that the bolt 300 installed at the bolt through hole 211 can perform a telescopic motion with respect to the lock body 200. The mounting groove 212 is disposed at one side of the latch bolt through hole 211 and is communicated with the latch bolt through hole 211, and the mounting groove 212 may be a sink groove 420 with a single side opening, or the mounting groove 212 may also be a groove-shaped structure with two or three side openings. Alternatively, the lock body 200 may be provided with a mounting hole penetrating through the lock body 200, and the lock body 200 may be fixedly mounted on a door panel by means of a screw or the like.

The latch tongue 300 can be formed by a metal structure through die casting and the like, the type of the latch tongue 300 can be a square tongue or a latch tongue, and the size of the latch tongue 300 is matched with that of the latch tongue through hole 211, so that the latch tongue 300 can stretch and contract relative to the lock body 200 through the latch tongue through hole 211, the latch tongue 300 can be inserted into the latch tongue through hole 211, or the latch tongue 300 can be separated from the latch tongue through hole 211, and the purposes of closing and opening the lock are achieved.

The rolling part 400 may have a ball-shaped structure, or the rolling part 400 may have a cylindrical structure, and the rolling part 400 is mounted in the mounting groove 212, so that the rolling part 400 can rotate relative to the lock body 200. Specifically, in the case where the rolling part 400 has a ball-type structure, the mounting groove 212 may have a ball-type structure, the rolling part 400 may be rotated with respect to the mounting groove 212 by mounting the rolling part 400 in the mounting groove 212, and in the case where the rolling part 400 has a cylindrical structure, the rolling part 400 may be mounted in the mounting groove 212 using a shaft hole structure, or the rolling part 400 may be mounted in the mounting groove 212 using a structure similar to a bearing.

Simultaneously, part roll portion 400 stretches out within the spring bolt perforation 211, roll portion 400 and spring bolt 300 rolling contact, and then at the in-process that the relative lock body 200 of spring bolt 300 carries out the flexible action, with the help of the roll portion 400 with spring bolt 300 rolling contact, can reduce the area of mutual contact between the parts that lie outside the spring bolt 300 such as spring bolt 300 and lock body 200, prevent that the spring bolt wearing and tearing condition from appearing after the tool to lock has used a period, guarantee that the tool to lock has higher security, and can reduce the size hard when opening and closing the tool to lock, and then reduce the flexible degree of difficulty of spring bolt 300, promote user experience.

In addition, the size of the part of the rolling part 400 extending into the bolt through hole 211 can be determined according to the size relationship between the bolt through hole 211 and the bolt 300, and the sum of the size of the bolt 300 and the size of the part of the rolling part 400 extending into the bolt through hole 211 is slightly smaller than the size of the bolt through hole 211 in the corresponding direction, so that the difficulty in extending and retracting the bolt 300 is further reduced. More specifically, the number of the rolling part 400 may be one, and the rolling part 400 may be located at an upper side, a lower side, a left side or a right side of the latch bolt 300, based on the case where the lockset is in a normal operation state. Of course, the rolling parts 400 may be provided on the upper, lower, left, and right sides of the latch bolt 300, and the number of the rolling parts 400 provided on the upper, lower, left, or right sides of the latch bolt 300 may be one, or the number of the rolling parts 400 provided on the upper, lower, left, or right sides of the latch bolt 300 may be plural, and the rotation axes of the plurality of rolling parts 400 coincide.

Preferably, the opposite sides of the locking bolt penetration hole 211 are provided with mounting grooves 212, and a rolling part 400 is provided in each mounting groove 212. Under the condition of adopting the above technical scheme, because the both sides that carry on back mutually of the spring bolt 300 all are provided with roll portion 400 to in the in-process that the relative lock body 200 of spring bolt 300 carries out the flexible action, can reduce the area of contact between the both sides that carry on back mutually of spring bolt 300 and lock body 200 simultaneously, thereby further reduce the flexible degree of difficulty of spring bolt 300.

Specifically, the shapes, sizes, installation positions, and the like of the two rolling parts 400 may be the same, so that on one hand, the difficulty of spare parts and assembly is reduced, and on the other hand, the telescopic action of the latch bolt 300 may be more stable. Alternatively, the two rolling parts 400 may be disposed above and below the latch bolt 300, respectively.

Optionally, the lock tongue 300 has a first locking surface and a second locking surface, the first locking surface and the second locking surface are arranged opposite to each other, the first locking surface and the second locking surface can be simultaneously limited with the lock hole, the purpose of closing the lock is achieved, and the reliability of the lock is relatively high. Specifically, the latch tongue 300 may be a square tongue, and the left side surface and the right side surface of the latch tongue 300 may be a first locking surface and a second locking surface, respectively, based on the situation that the lock is in a normal use state. Or, as shown in fig. 9 to 12, the locking tongue 300 may be a three-prong locking tongue 300, the locking tongue 300 includes a first locking portion 310 and a second locking portion 320, the first locking portion 310 has a first locking surface, the second locking portion 320 has a second locking surface, when the locking tongue 300 is engaged with a lock hole, the first locking portion 310 and one side surface of the lock hole are limited with each other, the second locking portion 320 and the other side surface of the lock hole are limited with each other, and the two side surfaces of the lock hole are opposite to each other.

Based on the latch bolt 300 disclosed in the above embodiment, preferably, as shown in fig. 9 to 12, two rolling parts 400 may be respectively provided at the left and right sides of the latch bolt 300, that is, one of the rolling parts 400 at both sides of the mounting groove 212 is in rolling contact with the first latching surface, and the other is in rolling contact with the second latching surface, and the surface areas of the first latching surface and the second latching surface are larger compared to the upper and lower sides of the latch bolt 300; and, in the process of user's switch tool to lock, usually accompany the action of pushing away door or sliding door, at the in-process of pushing away door and sliding door, can further aggravate between first locking surface (or second locking surface) and the lockhole, and, the degree of extrusion between second locking surface (or first locking surface) and the lock body 200, increase spring bolt 300 and lockhole, and the frictional force between spring bolt 300 and the lock body 200, therefore, compare and set up in the upside or the downside of spring bolt 300 in roll portion 400, through making two roll portions 400 respectively with first locking surface and second locking surface rolling contact, can furthest reduce the flexible degree of difficulty of spring bolt 300, promote user experience.

Alternatively, as shown in fig. 1 to 3, the rotation axis of the rolling part 400 is located in the installation groove 212, in this case, the part of the rolling part 400 extending out of the installation groove 212 may be relatively small, so that during the rolling contact of the locking bolt 300 and the rolling part 400, the situation that the locking bolt 300 is stuck with the rolling part 400 due to the movement of the locking bolt 300 to the rotation axis close to the rolling part 400, which affects the normal operation of the lock; moreover, with the above technical solution, because the part of the rolling part 400 extending out of the mounting groove 212 is relatively small, the size of the bolt 300 can be enlarged within a certain range, so that the gap between the bolt 300 and the lock body 200 (or the side wall of the bolt through hole 211) is relatively small, and the quality and safety of the lock are improved.

Specifically, the maximum size of the portion of the rolling part 400 extending into the bolt through hole 211 may be one fifth to one third of the radius of the rolling part 400, so that the bolt 300 has high quality and safety, and low expansion difficulty. In the case where the rolling part 400 has a cylindrical or substantially cylindrical structure, the rotation axis of the rolling part 400 may be an axis passing through the center of the rolling part 400, and in the case where the rolling part 400 has a spherical structure, the rotation axis of the rolling part 400 may be a straight line on which a diameter of the rolling part 400 perpendicular to the extending and retracting direction of the latch 300 is located.
