Abstract
Description
Technical Field
[0001] This utility model relates to locks, specifically to a highly stable thin lock. Background Technology
[0002] Currently, there is a type of lock on the market mainly used to control the opening or closing of switches, particularly in elevators, machinery, vehicles, and fire protection systems. This type of lock mainly includes a lock cylinder, lock case, key, switch base, and switch. The switch button is usually located on top of the switch; the lock cylinder rotates to contact the button on top of the switch, thus actuating the switch. This structure results in a relatively long lock, making it difficult to install in confined spaces. Furthermore, the switch needs to be first fastened to the switch base, and then the switch base is fastened to the lock case, making assembly cumbersome, involving many steps, and requiring significant labor intensity for workers. Utility Model Content
[0003] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a highly stable thin lock for solving the above problems.
[0004] Therefore, this utility model is implemented using the following solution:
[0005] A highly stable thin lock includes a key, a lock shell, and a lock cylinder. The lock cylinder is rotatably disposed within the lock shell. The lock cylinder is characterized by having a rotating core fitted at its bottom, a base at the bottom of the lock shell, a first switch and a second switch disposed within the base, the first and second switches being connected to the lock shell via fasteners, the first and second switches pressing the base firmly against the lock shell, a first button on the side wall of the first switch, a second button on the side wall of the second switch, and a first contact block extending from the rotating core that can contact the first button, and a second contact block that can contact the second button.
[0006] The bottom of the lock cylinder is provided with a slot, and the rotating cylinder has a locking foot that can be inserted into the slot.
[0007] The lock cylinder is provided with an insertion head, and the key is provided with a slot corresponding to the shape of the insertion head.
[0008] The key has a insertion / removal groove and a first limiting groove on its side wall, and the lock housing has a first limiting pin that can extend into the insertion / removal groove and the first limiting groove.
[0009] The lock cylinder has a second limiting groove on its side wall, and the lock housing has a second limiting pin that extends into the second limiting groove.
[0010] The lock cylinder has a spring hole, and a spring is installed in the spring hole. The spring presses the steel ball tightly against the inner wall of the lock shell. The inner wall of the lock shell is provided with a positioning groove for the steel ball to be inserted.
[0011] The aforementioned technical solution provides a highly stable, thin lock. By placing the switch button on the side and incorporating a rotating core with side-pressing contact, it replaces the traditional top-mounted button structure. This effectively reduces the overall length of the lock, facilitating its installation in confined spaces. Furthermore, this structure allows for the insertion and snap-fit of various components, necessitating only the fasteners to secure the switch to the lock housing. This simplifies assembly, improves efficiency, and reduces worker fatigue. Attached Figure Description

[0019] As shown in the figure, this utility model discloses a high-stability thin lock, including a key 1, a lock shell 2, and a lock cylinder 13. The lock cylinder 13 is rotatably disposed inside the lock shell 2. A rotating core 22 is fitted at the bottom of the lock cylinder 13. A base 3 is provided at the bottom of the lock shell 2. A first switch 25 and a second switch 27 are disposed inside the base 3. The first switch 25 and the second switch 27 are connected to the lock shell 2 by fasteners 28. A first threaded hole 4 is provided on the lock shell 2 to cooperate with the fasteners 28. The first and second switches press the base 3 tightly against the lock shell 2. A second threaded hole 10 is provided on the base 3 to cooperate with the fasteners. A first button 26 is provided on the side wall of the first switch 25, and a second button is provided on the side wall of the second switch 27. A first contact block 24 that can contact the first button 26 and a second contact block 29 that can contact the second button are extended from the rotating core 22.
[0020] Furthermore, the bottom of the lock cylinder 13 is provided with a slot 14, and the rotating cylinder 22 has a locking foot 23 that can be locked into the slot 14. With the above structure, the lock cylinder 13 and the rotating cylinder 22 can be locked together. By controlling the key 1 to drive the lock cylinder 13 to rotate, the rotating cylinder 22 can be driven to rotate synchronously.
[0021] Furthermore, the lock cylinder 13 is provided with an insertion head 11, and the key 1 is provided with a slot corresponding to the shape of the insertion head 11, so as to facilitate the transmission between the key 1 and the lock cylinder 13.
[0022] Furthermore, the side wall of key 1 is provided with an insertion / removal groove 17 and a first limiting groove 16, and the lock housing 2 is provided with a first limiting pin 18 that can extend into the insertion / removal groove 17 and the first limiting groove 16. The side wall of lock housing 2 has a first through hole 6 for the first limiting pin 18 to pass through. With the above structure, the key 1 can be positioned and inserted, and the rotation angle of key 1 can be limited to ensure the stable operation of the lock.
[0023] Furthermore, the lock cylinder 13 has a second limiting groove 12 on its side wall, and the lock housing 2 has a second limiting pin 19 extending into the second limiting groove 12. The lock housing 2 has a second through hole 7 through which the first limiting pin passes. With the above structure, the rotation angle of the lock cylinder 13 can be limited to ensure that the lock cylinder 13 can rotate to the required angle so that the rotating core 22 can contact the button to realize the control of the switch.
[0024] Furthermore, the lock cylinder 13 has a spring hole 15, and a spring 21 is installed inside the spring hole 15. The spring 21 presses the steel ball 20 tightly against the inner wall of the lock housing 2. The inner wall of the lock housing 2 is provided with a positioning groove 8 for the steel ball 20 to be inserted. With the above structure, the lock cylinder 13 can be limited to the unlocking and locking angles, ensuring the stability of the lock cylinder 13 after it has been rotated to the correct position. At the same time, it can provide a certain damping feedback force so that the user knows that it has been rotated to the correct position.
[0025] Furthermore, the base 3 is provided with a positioning post 9, and the bottom of the lock housing 2 is provided with a positioning hole 5 for the positioning post 9 to be inserted. This facilitates the positioning and locking of the base 3 and the lock housing 2.
[0026] The working principle of this utility model is as follows: by inserting the key 1 into the lock cylinder 13, and then turning the key 1 to drive the lock cylinder 13 to rotate, the rotating cylinder 22 can be driven to rotate. When the first and second contact blocks on the rotating cylinder 22 contact and press with the first and second buttons respectively, the action of the first and second switches can be controlled to realize the opening and closing control of the lock. When assembling this structure, the lock cylinder 13 can be placed into the lock shell 2 first, then the rotating cylinder 22 can be inserted into the lock cylinder 13, then the switch can be installed into the base 3, and finally the switch can be assembled and fixed by fasteners.
[0027] This invention, by placing the switch button on the side and using a rotating core with side-pressing contact, replaces the traditional top-mounted button structure. This effectively reduces the overall length of the lock, facilitating its installation in confined spaces. Furthermore, this structure allows for the insertion and snap-fit of various components, necessitating only the fasteners to secure the switch to the lock housing. This simplifies assembly, improves efficiency, and reduces worker fatigue.
