Technical Field

[0001] This application relates to the field of door locks, and more specifically, to a single-cylinder lock that is easy to push up and down. Background Technology

[0002] With technological advancements and diversified interior design methods, the applications of sliding doors have become increasingly varied and extensive. Besides being the most common partition doors, sliding doors are widely used in bookcases, wardrobes, living rooms, showrooms, and as sliding entrance doors. Currently, the sliding mechanism of a single-cylinder lock slides along a track, which is prone to misalignment and damage during use, thus necessitating improvements to the existing single-cylinder lock. Summary of the Invention

[0003] The purpose of this application is to provide a single-bar lock that is easy to push up and down, which can solve the above-mentioned technical problems.

[0004] This application provides a single-cylinder lock that is easy to push up and down, including a lock body, a pusher, a transmission component, a spring, a limiting component, a fixing component, and a lock hook. The front end of the lock body is provided with a strip-shaped clearance hole. The pusher is slidably installed in the strip-shaped clearance hole. The lower end of the transmission component is fixedly connected to the pusher. The transmission component is provided with a mounting groove. One end of the lock hook is installed in the mounting groove through the fixing component. The hook body of the lock hook extends out of the lock body. The limiting component is installed in the lock body and is located above the transmission component. The spring is pre-compressed between the limiting component and the transmission component. A first steel ball is provided between the pusher and the inner wall of the mounting groove. A second steel ball is provided between the pusher and the lock body.

[0005] Preferably, limit plates are provided at both the left and right ends of the back of the lock body, and the transmission component and the limit component are installed between the limit plates.

[0006] Preferably, the limiting plate is L-shaped and is integrally formed with the lock body.

[0007] Preferably, a third steel ball is provided between the limiting plate and the transmission component.

[0008] Preferably, the fixing member and the transmission member are connected by screws, and at least four screws are provided.

[0009] Preferably, the pusher is elongated, with a groove at its front end and anti-slip texture on the inner wall of the groove.

[0010] Preferably, the lock body, the pusher, the transmission component, the fixing component, and the limiting component are all made of metal.

[0011] The beneficial effects of this utility model are:

[0012] This utility model provides a single-cylinder lock that is easy to push up and down, including a lock body, a pusher, a transmission component, a spring, a limiting component, a fixing component, and a lock hook. The front end of the lock body has a strip-shaped clearance hole, and the pusher is slidably installed in the strip-shaped clearance hole. The lower end of the transmission component is fixedly connected to the pusher, and the transmission component has a mounting groove. One end of the lock hook is installed in the mounting groove through the fixing component, and the hook body extends outside the lock body. The limiting component is installed inside the lock body and is located above the transmission component. The spring is pre-compressed between the limiting component and the transmission component. The pusher and the inner wall of the mounting groove... A first steel ball is provided between the pusher and the lock body, and a second steel ball is provided between the pusher and the lock body. In use, the monolock is installed on a door or window frame. Then, the monolock is brought close to another external lock frame, and the pusher is pushed upwards. Under the action of the transmission component, the lock hook moves up and down, locking with the external lock frame and compressing the spring. Conversely, pushing the pusher downwards causes the lock hook to move downwards and disengage from the external lock frame under the combined force of the spring and the transmission component. This invention replaces the guide rail between the transmission component and the lock body with a second steel ball, and adds a first steel ball between the pusher and the lock body, allowing sliding without a guide rail. This results in lower friction during use and reduces the likelihood of damage. Attached Figure Description

[0025] like Figure 1-3As shown, a single-cylinder lock that is easy to push up and down includes a lock body 1, a pusher 2, a transmission component 3, a spring 4, a limiting component 5, a fixing component 6, and a lock hook 7. The front end of the lock body 1 has a strip-shaped clearance hole 8. The pusher 2 is slidably installed in the strip-shaped clearance hole 8. The lower end of the transmission component 3 is fixedly connected to the pusher 2, and the transmission component 3 has a mounting groove 9. One end of the lock hook 7 is installed in the mounting groove 9 through the fixing component 6, and the hook body of the lock hook 7 extends outside the lock body 1. The limiting component 5 is installed inside the lock body 1 and is positioned above the transmission component 3. The spring 4 is pre-compressed between the limiting component 5 and the transmission component 3. The pusher 2 and the inner wall of the mounting groove 9 are... A first steel ball 10 is provided between the pusher 2 and the lock body 1, and a second steel ball 11 is provided between the pusher 2 and the lock body 1. In use, the single-cylinder lock is installed on a door or window frame, and then the single-cylinder lock is brought close to another external lock frame. The pusher 2 is pushed upward, and the lock hook 7 moves up and down under the action of the transmission 3. The lock hook 7 locks with the external lock frame, and the spring 4 is compressed. Conversely, the pusher 2 is pushed downward, and under the action of the spring 4 and the transmission 3, the lock hook 7 moves downward and disengages from the external lock frame. In this invention, the guide rail between the transmission 3 and the lock body 1 is replaced with the second steel ball 11, and the first steel ball 10 is added between the pusher 2 and the lock body 1. Sliding can be completed without a guide rail, and the friction is small during use, making it less prone to damage.

[0026] In this embodiment, limit plates 12 are provided at both the left and right ends of the back of the lock body 1, and the transmission component 3 and the limit component 5 are installed between the limit plates 12. The limit plate 12 is L-shaped and is integrally formed with the lock body 1. The limit component 5 of this utility model can prevent the transmission component 3 from moving excessively upward and fix the spring 4. The limit plate 12 of this utility model can prevent the transmission component 3 and the limit block from moving left and right, so that the transmission component 3 moves straight up and down during the movement.

[0027] In this embodiment, in order to further reduce the friction of the transmission component 3, a third steel ball 13 is provided between the limiting plate 12 and the transmission component 3.

[0028] In this embodiment, the fixing member 6 and the transmission member 3 are connected by screws 14. There are at least four screws 14. When the locking hook 7 is damaged, the fixing member 6 can be directly removed and replaced.

[0029] In this embodiment, the pusher 2 is elongated and has a groove 15 at its front end. The inner wall of the groove 15 is provided with anti-slip texture 16, which prevents the hand from slipping when pushing.

[0030] In this embodiment, in order to extend the service life of the present invention, the lock body 1, the pusher 2, the transmission member 3, the fixing member 6, and the limiting member 5 are all made of metal.

[0031] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
