Description

Latch bolt assembly for electronic lock

Technical Field

The utility model relates to a latch bolt subassembly for electronic lock.

Background

The electronic lock is a lock controlled by an electric signal to open and close, compared with the traditional mechanical lock, the electronic lock has the advantages of convenient use, higher safety and the like, the electronic lock usually comprises a shell, a main lock tongue, an oblique tongue, a transmission component and a main board for receiving the electric signal to control the transmission component, the shell is provided with a plurality of openings through which the main lock tongue and the oblique tongue can respectively extend and retract, the main lock tongue and the oblique tongue are in transmission fit with the transmission component, the main lock tongue can extend out or retract under the driving of the transmission component so as to form or relieve the back lock of the door, the oblique tongue is arranged to be gradually reduced from outside, a first abutting surface and a second abutting surface are formed, the first abutting surface is attached to the inner wall of one side of the door frame, which is close to the outside, the first abutting surface is abutted to the door frame lock hole in a normal state, when a user pushes the door outwards, the door handle needs to rotate to enable the oblique tongue to integrally retract so as to open the door lock hole, the second abutting surface is obliquely arranged, when a user closes the door, the second abutting surface obliquely abutted against the outer wall of the door frame can generate a component force towards the retraction direction of the oblique tongue, so that the oblique tongue is retracted into the shell, in the process, only part of force applied by the user to the door is converted into kinetic energy for promoting the retraction of the oblique tongue, in the specific process of closing the door, on one hand, the second abutting surface of the oblique tongue is firstly contacted and collided with the door frame by being close to the opening of the shell to promote the oblique tongue to be converted into a motion state from a static state, at the moment, the maximum static friction force larger than the sliding friction force is required to be overcome to promote the start of the oblique tongue, on the other hand, the position of the second abutting surface of the oblique tongue close to the opening of the shell can possibly present an arc-shaped excessive chamfer or plane state, the proportion of the component force converted into the retraction direction of the door is low when the oblique tongue is contacted and extruded with the door frame, so that the oblique tongue collides with the door frame when the door exists, the situation that the door cannot be smoothly closed occurs, and in the past, the outer wall part of the door frame corresponding to the second abutting surface is easily abraded, paint is dropped, deformation and other injuries are caused, the attractiveness of the door frame is affected, further, the shape of the opening is deformed along with the outer wall part of the door frame, and the problems that the door is opened/closed difficultly, looseness exists between the door and the door frame and the like are caused.

SUMMERY OF THE UTILITY MODEL
