Detailed Description

The present invention will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present invention more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.

As shown in fig. 1 to 3:

the lock benefit component of the thin sliding door lock disclosed by the embodiment of the invention is characterized in that the lock benefit head 1 is internally provided with the safety hook 3, the safety hook 3 can extend out from the lock benefit head 1 to hook the door catch 2 when the lock benefit head 1 is locked, and can be automatically reset into the lock benefit head 1 when the lock benefit head 1 is unlocked.

The specific structure can be as follows: the lock cylinder shell 4 is internally provided with a lock cylinder head 1 and a lock cylinder push rod 5 which can horizontally move back and forth and a lock cylinder gear 6. Wherein, two inner side walls of the lock cylinder shell 4 are provided with guide limit grooves 41 which are horizontally arranged, and the corresponding positions of the side surfaces of the lock cylinder head 1 are provided with guide limit shafts 14; when assembled, the lock cylinder head 1 is movably arranged in the lock cylinder shell 4 back and forth, and the guide limiting shaft 14 is movably clamped in the guide limiting groove 41 back and forth. The safety hook 3 is 7-shaped, one end of the safety hook is rotatably arranged in the lock catch head 1 through a fixing pin 32 of a torsion spring 31, and the other end of the safety hook is downwards bent and extended, and extends out of the lock catch head 1 to hook the door catch 2 during locking. The lock catch push rod 5 is provided with a tooth 51, the lock catch gear 6 is meshed with the tooth 51, and one end of the lock catch push rod 5 is simultaneously in driving connection with the lock catch head 1 and the safety hook 3 so as to drive the lock catch head 1 to extend out of the lock catch shell 4 to realize locking and the safety hook 3 to extend out of the lock catch head 1 to hook the door holder 2; as shown in the figure, a hollow cavity 11 is arranged in the lock head 1, the upper end and the inner end of the hollow cavity 11 are both provided with externally communicated openings, the lower surface of the outer end of the lock head 1 is provided with a safety hook extending opening 12 communicated with the hollow cavity 11, and a driving limit groove 13 is arranged at the position, close to the opening of the inner end, of the upper end opening; one end of the lock plunger 5 is provided with a driving head 52 and a movement limiting part 53 arranged at two sides of the driving head 52, and the tooth 51, the driving head 52 and the movement limiting part 53 are integrally formed with the lock plunger 5; when in assembly, the driving head 52 is arranged in the hollow cavity 11 and props against the safety hook 3, and the movement limiting part 53 is clamped in the driving limiting groove 13. When the lock gear 6 drives the lock push rod 5 to push the lock head 1 to a locking state, the lock push rod 5 continues to push, so that the safety hook 3 extends out of the lock head 1 to hook the door catch 2; when unlocking, the lock catch gear 6 drives the lock catch push rod 5 to reset, at the moment, the safety hook 3 automatically resets into the lock catch head 1 (under the action of the torsion spring 31), and then the lock catch head 1 retracts to an unlocking state (under the action of the lock catch push rod 5); the process movement limiting part 53 moves in the drive limiting groove 13.

Therefore, the lock mechanism of the thin sliding door lock can lock the lock head 1 and hook the door catch 2 through the safety hook 3 by arranging the safety hook structure, has a safety function, extremely high anti-theft performance and safety, is simple and ingenious in structure, is easy to produce and process, and is beneficial to mass production popularization and use.

In addition, the bottom of one side of the driving head 52 facing the safety hook 3 is a smooth circular arc chamfer, one side of the safety hook 3 facing the driving head 52 is a smooth surface, and the smooth circular arc chamfer of the driving head 52 is in contact with the smooth surface of the driving head 52 in a back-and-forth sliding manner. Therefore, the safety hook 3 can be controlled in the using process of the thin sliding door lock locking component, the operation is smoother and easier, and the performance is more stable.

While the foregoing is directed to the preferred embodiments of the present invention, it will be appreciated by those skilled in the art that changes and modifications may be made without departing from the principles of the invention, such changes and modifications are also intended to be within the scope of the invention.
