The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

The embodiment relates to a door and window opening locking device which is used for locking the opening of a fixed frame body 1 and a door and window frame body 2 which are hinged together, so that the door and window frame body can be fixed at any opening angle relative to the fixed frame body 1.

It should be noted that the fixed frame 1 may be, for example, a door frame or a window frame fixed on a wall, and the door/window frame 2 may be, for example, a door leaf or a window sash.

Based on the above design principle, as an exemplary structure, the locking device for the opening of the door or window of the present embodiment, as shown in fig. 1 and 2, mainly includes an angle adjusting lever 5 disposed between the fixed frame 1 and the door or window frame 2, and a rotating lever 4 rotatably disposed on the door or window frame 2. The door/window frame 2 is provided with a limiting member 8 having a plurality of locking grooves 801, and the plurality of locking grooves 801 are arranged at intervals along the axial direction of the rotating rod 4. The rotating rod 4 passes through the limiting member 8, the angle adjusting rod 5 has a hinged end hinged to the fixed frame 1 and a sliding end slidably disposed on the rotating rod 4, the sliding end is provided with a locking block 701 sliding along the rotating rod 4, the locking block 701 has a locking state capable of being clamped into one of the locking grooves 801 along with the rotation of the rotating rod 4 and an unlocking state capable of being separated from the locking groove 801 along with the reverse rotation of the rotating rod 4, and the locking block 701 can be locked in different locking grooves 801 to maintain the locking of the door/window frame 2 on the fixed frame 1 at different opening degrees.

Specifically, as shown in fig. 2 and 3, the stopper 8 of the present embodiment is formed with a sliding groove communicating with the plurality of locking grooves 801, and both ends of the stopper 8 are provided with mounting holes through which the rotating rod 4 passes, and the stopper 8 is fixed to one side end of the door/window frame 2. And one end of the angle adjusting rod 5 forms a hinged end, the other end forms a sliding end, the hinged end is hinged and connected to the fixed frame body 1, and the sliding end slides on the rotating rod 4. And as a preferred embodiment, the sliding end is provided with a sliding piece 7 sliding along the sliding groove.

As shown in fig. 4 and 5, the sliding member 7 of the present embodiment specifically includes a connecting block 700 hingedly connected to the sliding end. For the end connected with the sliding end, the other end of the connecting block 700 is provided with two sliding blocks arranged at intervals, and the locking block 701 is positioned between the two sliding blocks. Therefore, when the sliding block slides in the sliding groove, the locking block 701 can be driven to slide along the rotating rod 4.

As a preferred embodiment of the present embodiment, the structure of the locking block 701 of the present embodiment is as shown in fig. 5, and with reference to fig. 4, the locking block 701 has a through hole 7010 through which the rotating rod 4 passes, so that the rotating rod 4 passes through the through hole 7010, which facilitates the sliding connection of the locking block 701 on the rotating rod 4.

In order to prevent the locking block 701 from rotating relative to the rotating rod 4 when the rotating rod 4 rotates, in the present embodiment, as shown in fig. 5 and 6, a limiting structure for limiting the rotation of the locking block 701 relative to the rotating rod 4 is provided between the locking block 701 and the rotating rod 4.

In detail, as shown in fig. 5 and fig. 6, the limiting structure specifically includes a limiting block 7011 disposed on the wall of the through hole 7010, and a limiting groove 401 disposed on the outer peripheral surface of the rotating rod 4 and recessed toward the inside thereof. Wherein, the cross section of stopper 7011 and spacing groove 401 all is rectangle column structure, from this, slides in spacing groove 401 through stopper 7011, can realize that locking piece 701 can slide along bull stick 4 smoothly, also can carry out better restriction to locking piece 701 and bull stick 4 relative rotation simultaneously to do benefit to the reliability of locking piece 701 locking in spacing groove 401.

It can be understood that, in addition to the structural form of the limiting block 7011 formed on the hole wall of the through hole 7010 and the limiting groove 401 formed on the outer peripheral surface of the rotating rod 4, the positions of the limiting block 7011 and the limiting groove 401 can be interchanged, that is, the limiting block 7011 is disposed on the outer peripheral surface of the rotating rod 4, and the corresponding limiting groove 401 engaged with the limiting block 7011 is disposed on the hole wall of the through hole 7010, which is also feasible. In addition, it can be understood that, besides the above structural forms, the limiting structure of the present embodiment may also adopt other forms of limiting structures.

To facilitate the rotation of the rotation rod 4, in this embodiment, as shown in fig. 1 and fig. 2, a driving member for driving the rotation rod 4 to rotate is disposed on the door window frame 2.

Specifically, the driving member includes a driving rod 3 slidably provided in the door/window frame 2, and a link 6 connected to the driving rod 3 and the rotating rod 4, respectively. The driving rod 3 and the rotating rod 4 are respectively positioned on two adjacent side end faces of the door and window frame body 2, one end of the connecting rod 6 is hinged to the end part of the driving rod 3, the other end of the connecting rod is hinged to the end part of the rotating rod 4, and the connecting point of the connecting rod 6 and the rotating rod 4 is eccentrically arranged with the center of the end face of the rotating rod 4. So can make actuating lever 3 when following door and window frame 2 rectilinear movement, can drive bull stick 4 through connecting rod 6 and rotate to can drive locking piece 701 on the bull stick 4 and rotate, and make locking piece 701 can change over to in one of them locking groove 801, realize door and window frame 2 and open certain angle in fixed frame 1, and the locking that can be better keeps opening the back state.

As a further improvement of this embodiment, in this embodiment, a handle for opening and closing the door and window frame 2 is disposed on the door and window frame 2, one end of the driving rod 3 constitutes a driving end for connecting with the connecting rod 6 and driving the connecting rod 6 to rotate, and the other end constitutes a force bearing end for connecting with the handle and bearing an external force on the handle.

It should be noted that the connection between the handle and the driving rod 3 can be a connecting rod 6 mechanism in the prior art, so that when the handle rotates, the driving rod 3 can be driven to perform reciprocating linear motion along the side end face of the door/window frame 2 where the driving rod is located, and thus the rotating rod 4 can be driven to rotate under the reciprocating linear motion of the driving rod 3.

After the door and window frame body 2 rotates to a proper angle, the driving rod 3 is driven to move linearly through rotation of the handle, and the rotating rod 4 is driven to rotate, so that the locking block 701 can be locked in one locking groove 801, and locking of the door and window frame body 2 in a state after the angle is opened is achieved. In addition, the driving rod 3 is reversely moved by the reverse rotation of the handle, and the rotating rod 4 is driven to reversely rotate, so that the locking block 701 is separated from one locking groove 801, and the opening angle of the door and window frame 2 can be adjusted.

The door and window opening locking device of the embodiment is simple in structure and convenient to operate, the locking block 701 can be clamped into the locking groove 801 along with the rotation of the rotating rod 4, the locking of the door and window frame body 2 at different opening angles relative to the fixed frame body 1 can be achieved, a good locking effect is achieved, and a good using effect is achieved.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
