Description

Button pressing structure of indoor lock

Technical Field

The utility model relates to an indoor lock, in particular to a button pressing structure of an indoor lock.

Background

The handle is arranged inside and outside the common indoor lock, the variety of the indoor lock is various, the unlocking mode is also various, some of the common indoor lock is used for driving the lock tongue to unlock through rotating the handle, and other of the common indoor lock is used for unlocking through pressing the button up and down.

The structure of a pressing lock on the market at present is that: the lock comprises a core shell which is composed of a bottom shell and a face cover, wherein a connecting rod, a water drop-shaped lock disc and a button which slides up and down are arranged in the core shell, one end of Fang Zhi is connected with the lock disc, a square branch is connected with a lock cylinder at the same time, the connecting rod is hinged with the button and the lock disc, the button drives the lock disc to rotate through the connecting rod, so that when the button is pressed down, the connecting rod drives the lock disc to rotate, the lock disc drives the square branch to rotate, when the lock disc rotates, a lock tongue in the lock cylinder is driven to retract, unlocking is realized, and after the button is released, the button is extruded through a torsion spring arranged in the core shell, and then the lock disc is driven to reset through the connecting rod, so that the lock tongue is reset.

In the above structure, the pressing force is applied along the sliding direction of the button, but the elastic force of the torsion spring does not always act on the button along the sliding direction of the button, so that the friction between one side of the button and the wall of the pressing groove is relatively large during pressing, and the pressing process is blocked, and the stroke of the button and the rotating angle of the lock disc are not in linear relation during pressing, so that the earlier stage button moves a relatively large distance, but the connecting rod only drives the lock disc to rotate by a small angle, and the rotating angle of the lock disc is suddenly increased after the connecting rod rotates to a critical point, so that the hand feeling fed back to a user is not smooth, the earlier stage hand feeling is relatively soft, and the later stage hand feeling is relatively hard.

Disclosure of Invention

In order to overcome the defects in the prior art, the utility model provides an indoor lock button pressing structure.

The technical scheme adopted for solving the technical problems is as follows:

the utility model provides an indoor lock button press structure, includes branch, core shell and sets up the lock dish in the core shell, fang Zhi is connected its characterized in that with the lock dish: the sliding plate is characterized in that a reset spring, a sliding groove and a sliding plate capable of sliding along the sliding groove are arranged in the core shell, a button is arranged at the end part of the sliding plate, a button hole is formed in the bottom surface of the sliding groove, a sliding hole is formed in the sliding plate, hole teeth are formed in the hole walls of the two sides of the sliding hole, a disc tooth meshed with the hole teeth is arranged on the end part of the locking disc, located in the sliding hole, of the end part of the locking disc, and one end of the reset spring abuts against the sliding plate while the other end of the reset spring abuts against the core shell.

The end of the lock disk is a cylinder.

The bottom surface of spout is equipped with the mounting groove, reset spring is located this mounting groove.
