Embodiment 1

[0041] see Figure 1-Figure 8 As shown, a locking type glass door lock is mainly composed of a lock body 11, a gland 29, a deadbolt movement mechanism installed in the lock body 11, a torsion wheel 13 and its first spring return device, the second spring return device, Backstop 15 and lock cylinder 41 form. The dead bolt movement mechanism comprises dead bolt 14, slide block 12, the 1st positioning post 114 and the 2nd positioning post 115, and dead bolt 14 is fixed on the front end of slide block 12, and the first guide groove 126 of slide block 12 and the 2nd guide groove 127 are matched and slidably connected with the first positioning column 114 and the second positioning column 115 fixed in the lock body 11 respectively, and the dead bolt 14 is located at the front end portion of the lock body 11 at the edge lock opening 112 . The shaft of the twist wheel 13 is installed in the first shaft hole 1112 on the lock body 11 and the second shaft hole 291 on the gland 29 . The...

Embodiment 2

[0062] see Figure 9 , Figure 10 As shown, the structure of the lockable glass door lock of this embodiment is basically the same as that of the lockable glass door lock of Embodiment 1, the difference is that the first guide groove 126 and the second guide groove of the slider 12 Between 127 there is also a seventh positioning post 120 recessed in the plane of the main body of the slider 12 and a pipe-shaped groove 1213 recessed in the main body of the slider 12 , the seventh positioning post 120 is located in the center of the pipe portion of the pipe-shaped recess 1213 . The front end of the seventh positioning column 120 is provided with a fifth overlapping surface 1202 , and the rear end of the seventh positioning column 120 is provided with a sixth overlapping surface 1201 .

[0063] The 8th positioning post 150 that protrudes is provided with the 8th positioning post 150 that protrudes in the center of the positioning rod 15 main body between the 5th positioning post ...

Embodiment 3

[0073] see Figure 11 , Figure 12 As shown, the structure of the lockable glass door lock of this embodiment is basically the same as that of the lockable glass door lock of Embodiment 2, except that the sixth overlapping surface 1201 of the seventh positioning post 120 of the slider 12 The 3rd semicircle positioning groove 1203 is added in the lower part of the locating bar 15, and the 3rd front 1502 lower part of the 8th positioning column 150 of the positioning rod 15 is additionally provided with the 3rd semicircle positioning column 1503. catch. In the closed state, the third semicircular positioning column 1503 is hooked with the third semicircular positioning groove 1203 to prevent the positioning rod 15 from dislocating and moving outward when the deadbolt 14 is subjected to a strong external force and loses the positioning and locking function.

[0074] In general, the lock-type glass door lock of embodiment 3 has the most powerful locking function, followed by the...

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 ...
