[0002] A mechanical lock is a type of lock based on mechanical principles. It uses the cooperation of mechanical components such as a key, lock cylinder, bolt, and lock body to achieve the functions of unlocking and locking. When a key is inserted into the lock cylinder, rotating the key moves the pins and other components inside the lock cylinder, causing the bolt to extend or retract, thereby controlling the opening and closing of doors and other objects. It is characterized by its simple structure, high reliability, and low cost, and is widely used in many fields such as homes, businesses, and industries to provide people with basic security protection.
[0003] Visualized lock cylinder status mechanical locks are innovative upgrades based on traditional mechanical locks. They integrate the basic structure of mechanical locks with visualization functions. Through built-in miniature cameras, optical display devices, mechanical indicators or electronic displays, users can intuitively understand whether the lock cylinder is unlocked, locked or key inserted without additional operation. This provides more convenience and security for people using mechanical locks and improves the user experience of traditional mechanical locks.
[0004] The display screens of some existing visual lock cylinder status mechanical locks are exposed to the outside world, and dust and other contaminants will stick to the surface, reducing the clarity of the display screen and affecting its use. To address this problem, a visual lock cylinder status mechanical lock is proposed. Utility Model Content

[0011] The mechanical lock assembly includes a lock body, a screen is fixedly connected inside the lock body, a door handle is fixedly connected to the front end of the lock body, and a keyhole is rotatably connected inside the lock body;
[0012] As a further description of the above technical solution:
[0013] The dustproof plate has a sliding groove inside, and the push plate is slidably connected to the inside of the dustproof plate from the outside.
[0014] As a further description of the above technical solution:
[0015] The rear end of the spring is fixedly connected to the front end of the fixing block, and the inside of the limiting sleeve is provided with a sliding groove.
[0016] As a further description of the above technical solution:

[0022] This utility model has the following beneficial effects:
[0023] 1. In this utility model, by rotating the dustproof plate, the rotating ring is driven to rotate until the rear end of the brush plate contacts the front end of the screen. At the same time, the dustproof plate drives two limit hooks to slide and connect to the left and right ends of the lock body. Pushing the insertion shaft downward, the dustproof plate is fixed by the sliding connection between the insertion shaft and the limit hooks and by the cooperation between the limit frame and the insertion shaft. Pushing the push plate drives the brush plate to slide up and down to clean the screen surface, thereby achieving the effect of preventing stains from adhering to the display screen surface.
[0024] 2. In this utility model, when the user pulls the door open with the door handle, the door moves the lock body and the door handle due to inertia. At the same time, the lock body moves the limit sleeve and the buffer pad through the fixing block. When the buffer pad hits the wall, the spring cushions the buffer pad, thus solving the problem of the door handle hitting the wall and being damaged due to inertia when the user opens the door.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0034] Reference Figures 1 to 3This utility model provides an embodiment of a visual lock cylinder status mechanical lock, including a dustproof plate 1, which provides protection for subsequent components. Rotating rings 2 are fixedly connected to both ends of the dustproof plate 1, allowing for smoother rotation of the dustproof plate 1. Fixed shafts 3 are rotatably connected inside each of the two rotating rings 2, providing support and limiting for the dustproof plate 1 and the rotating rings 2.
[0035] Two limiting hooks 4 are fixedly connected to the rear end of the dustproof plate 1. These hooks 4 cooperate with subsequent components to secure the dustproof plate 1. A sliding shaft 5 is slidably connected to the adjacent ends of the two limiting hooks 4. The sliding shaft 5 cooperates with the limiting hooks 4 to secure the dustproof plate 1. Two limiting brackets 6 are slidably connected to the outside of the sliding shaft 5. These brackets provide support and limit the sliding shaft 5, preventing it from falling. A brush plate 7 is slidably connected to the rear end of the dustproof plate 1. The brush plate 7, driven by related components, cleans subsequent components.
[0036] A push plate 8 is fixedly connected to the front end of the brush plate 7, providing a force point for the user to push. A mechanical lock assembly is fixedly connected to the outside of the fixed shaft 3, which can be locked or unlocked according to the user's needs. A buffer assembly is fixedly connected to the right end of the mechanical lock assembly, preventing subsequent components from colliding and being damaged due to inertia.
[0037] Reference Figure 1 , Figure 4 and Figure 5 The buffer assembly includes a fixing block 9, which provides stable support for subsequent components. Three limiting sleeves 10 are fixedly connected to the front end of the fixing block 9, providing limiting for internal components. A sliding rod 11 is slidably connected inside the limiting sleeve 10, allowing it to slide smoothly within the limiting sleeve 10.
[0038] A spring 12 is fixedly connected to the rear end of the sliding rod 11, which provides effective cushioning for the movement of the sliding rod 11. A buffer pad 13 is fixedly connected to the front end of the sliding rod 11. The buffer pad 13 is made of rubber material, which can reduce impact force and prevent damage to the wall.
[0039] Reference Figure 2 , Figure 4 and Figure 6The mechanical lock assembly includes a lock body 14, which provides support for related components and operating space for internal devices. A screen 15 is fixedly connected inside the lock body 14, displaying the lock cylinder's status to the user. A door handle 16 is fixedly connected to the front end of the lock body 14, providing a force point for the user to open and close the door. A keyhole 17 is rotatably connected inside the lock body 14, providing a key insertion position for unlocking and locking the mechanical lock. A groove is provided inside the dustproof plate 1, providing limiters for related components.
[0040] The push plate 8 is externally slidably connected to the inside of the dustproof plate 1, which provides a limit to the movement of the push plate 8. The rear end of the spring 12 is fixedly connected to the front end of the fixing block 9, which provides fixation and support for the spring 12 and prevents it from loosening. The limiting sleeve 10 has a groove inside, which provides a limit to the movement of related components. The sliding rod 11 has a slider on its outside, and the slider's structure is coupled with the groove of the limiting sleeve 10, limiting the movement of related components while allowing them to move smoothly. The left end of the fixing block 9 is fixedly connected to the right end of the mechanical lock assembly, which provides support for the fixing block 9 and related components at its front end.
[0041] The left and right ends of the locking body 14 are fixedly connected to the adjacent ends of the two limiting brackets 6, providing fixation and support for the limiting brackets 6. The front end of the screen 15 is slidably connected to the rear end of the brush plate 7, which can move up and down to clean the surface of the screen 15. The left and right ends of the locking body 14 are slidably connected to the inside of the dustproof plate 1, and the tight connection between the locking body 14 and the dustproof plate 1 improves the protective effect of the dustproof plate 1. The left and right ends of the locking body 14 are slidably connected to the adjacent ends of the two insertion shafts 5, ensuring smooth sliding of the insertion shafts 5 and preventing displacement.
[0042] Working principle: When using the mechanical lock, the user can observe the status of the lock cylinder inside the lock body 14 through the screen 15. After observation, the user rotates the dustproof plate 1, which drives the rotating ring 2 to rotate outside the fixed shaft 3. At the same time, the dustproof plate 1 drives the push plate 8 and the brush plate 7 to rotate. When the brush plate 7 rotates to the point where its rear end is in contact with the front end of the screen 15, the limit hook 4 moves to the appropriate position. At this time, the insertion shaft 5 is pushed down, and the insertion shaft 5 moves down inside the limit frame 6 to fix the limit hook 4 and the dustproof plate 1. The push plate 8 is pushed up and down, and the push plate 8 drives the brush plate 7 to move up and down on the surface of the screen 15. The brush plate 7 cleans the screen 15 and removes surface stains.
[0043] When the user pulls the door handle 16 to open the door, the lock body 14 drives the fixing block 9 to move synchronously under the action of inertia. The fixing block 9 drives the limiting sleeve 10, the sliding rod 11 and the buffer pad 13 to move. When the buffer pad 13 moves to hit the wall, the movement of the buffer pad 13 is limited by the deformation of the spring 12 to avoid the impact from damaging the door handle 16.
[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
