Technical Field

Background

The lock shaft bolt connecting mechanism is a connecting mechanism between a lock shaft and a lock bolt plate in the lockset. The lock shaft is a part connected with the door handle, and the latch plate is a part connected with the door bolt. Therefore, when the lockset is installed on the door body, the door handle is rotated and then the door bolt is driven to stretch through the connecting mechanism between the lock shaft and the lock bolt plate, so that the locking and unlocking of the door body are realized. The lock shaft is a rotatable member and the latch plate is a reciprocally retractable member. Thus, the latch spindle bolt connection is essentially a component that converts rotation into reciprocating linear motion. If the door body on which the lockset is installed only has one bolt, the bolt plate of the lockset only needs one. In this case, the prior art realizes various lock shaft bolt connection mechanisms, which are usually realized by a gear rack or a movable connecting rod.

The latch shaft 20 is perpendicular to the front panel 11, back panel 12 and mounting plate 13 and extends perpendicularly through the mounting plate 13 for attachment to a door handle grip. The bolt plate is a plate-shaped body, and has four blocks which are respectively: two first latch plates 21 and two second latch plates 22. The two first latch plates 21 and the two second latch plates 22 are respectively arranged oppositely and extend out of the box body 1 from the four side walls of the box body 1. The latch plates are connectors, typically two first latch plates 21 for connecting to the world bar of the vault door and two second latch plates 22 for connecting to the door latch of the vault door. The latch plate 2 and the latch spindle 20 are connected by a latch spindle bolt actuator 200. Therefore, when the lock shaft 20 is rotated by the handle of the door connected with the lock shaft, the lock shaft bolt transmission mechanism 200 drives the lock bolt plates 2 to synchronously extend and retract, and further drives the world lever of the vault door connected with the lock bolt plates 2 and the door bolt of the vault door to move, so that the locking and unlocking operations of the vault door are realized. The latch plate 2 and the latch spindle bolt actuator 200 are disposed within the first cavity 101. A locking mechanism 300 is disposed within the second chamber 102. The locking mechanism 300 is used to lock the latch plate 2 and the lock shaft 20, and the prior art implementation thereof is various and familiar to those skilled in the art, and is not in the scope of the present invention, and the detailed description thereof is not necessary.

Referring to fig. 1 and 4, a latch shaft latch actuator 200 for coupling the latch plate 2 and the latch shaft 20 includes a drive plate 23 and a gear 24. The first latch plate 21 and the second latch plate 22 are both plate-like bodies, and are arranged on the mounting plate 13 in a manner parallel to the mounting plate 13 by the slide limiting mechanism 29, so that the first latch plate 21 and the second latch plate 22 can translate in translation relative to the mounting plate 13. In this embodiment, the sliding limiting mechanism 29 is implemented by a plurality of slotted hole sliding limiting mechanisms.

The plurality of slotted hole sliding limiting mechanisms are matched to realize translational sliding limitation in a single direction. A drive plate 23 is provided on the lock shaft 20 parallel to the mounting plate 13. Thereby enabling the drive plate 23 to rotate about an axis perpendicular to its plate surface. The axis perpendicular to the surface of the transmission plate 23 is the axis of the lock shaft 20. The driving plate 23 is provided with two spiral grooves 231. Referring to fig. 5, the spiral grooves 231 are constant-speed spirals centered on the rotation axis of the driving plate 23, and the two spiral grooves 231 are centrosymmetric about the rotation axis of the driving plate 23. The constant velocity spiral of the spiral groove 231 means that the center line 230 of the spiral groove 231 is a constant velocity spiral.
