locking glass door lock

Abstract

The invention provides a locking and fixing type glass door lock. A twisting wheel is provided with an upper swing arm, a lower swing arm, a protruding hook and a limiting protruding column, wherein the upper swing arm and the lower swing arm are symmetric in an up-down mode. A first spring resetting device is arranged behind the upper end of the upper swing arm. A second spring resetting device is arranged in front of the lower end of the lower swing arm. The upper portion of a sliding block is provided with guide grooves and locating columns, wherein the locating columns make contact with locating columns arranged on a locating rod in a matched and overlapping mode. A fixing hole in the front end of the locating rod is movably connected with a fixing column of a lock body. An arc-shaped collision region of the locating rod makes contact with a boss of a lock cylinder in a sliding mode. A spring resetting device is arranged between the locating rod and the surrounding edge of the lock body. The guide grooves in the upper portion of the sliding block are connected with the locating columns of the lock body in a sliding mode. The rear end of the sliding block is provided with a slide block which is connected with the protruding hook of the twisting wheel in a contact and sliding mode. The lower portion of the sliding block is further provided with a spring resetting device. According to the locking and fixing type glass door lock, abrasion which may exist between a shaft of the twisting wheel and a matching shaft hole can be reduced to the maximum degree, so that the service life of the glass door lock is greatly prolonged, and the firmness of the locked glass door lock can be greatly improved; consequently, the anti-theft capability of the glass door lock is enhanced.

Description

technical field [0001] The invention relates to the technical field of glass door locks, in particular to a glass door lock. Background technique [0002] There is a glass door lock used for fortification. Its main functions are lock in, lock out and lock. Because the lock is a purely mechanical structure, it is often used in public places, so the lock is opened and closed very frequently. The torsion wheel of the glass door lock only uses one spring for resetting the torsion wheel. Under the one-way pressure of the spring, the shaft and shaft hole of the torsion wheel will be severely worn and elliptical after a period of use, and the spring will fatigue prematurely. , Fracture phenomenon. Especially when a heavy metal handle is installed, due to the insufficient pressure of the single spring at the initial stage, the heavy metal handle will sag. The wear between the shaft and the shaft hole is more serious, and there is even a safety hazard because children cannot twist ...
