Description

Technical Field

[0001] The utility model relates to the technical field of door locks, in particular to a door lock with a hidden keyhole. Background Art

[0002] Door locks, as an important component to ensure space security and privacy, are widely used on doors in various places such as homes, hotels, and offices. Its basic function is to ensure that the door is firmly locked when closed through a specific locking mechanism;

[0003] In the traditional door lock design, the keyhole is usually directly exposed outside the door, and the user inserts the key into the keyhole to open it. However, this design has certain safety risks. The exposed keyhole is easy to be observed and cracked by bad people. They may observe the shape and structure of the keyhole, or use various tools to try to open the door lock, thus posing a threat to the user's property safety;

[0004] In order to enhance the safety and ease of use of door locks, some designs combining door handles with door locks have appeared on the market. Such designs usually hide the keyhole inside or beside the door handle, and trigger the exposure and hiding of the keyhole through specific operations, such as rotation or pressing. However, although these designs have improved safety to a certain extent, they still need to be improved in terms of aesthetics and practicality. Therefore, we propose a door lock with a hidden keyhole. Utility Model Content

[0005] In view of the problems existing in the prior art, the utility model discloses a door lock with a hidden keyhole. The technical scheme adopted is that it includes a shell, a lock body and a keyhole, a lock body cavity is arranged at the inner right end of the shell, a lock body is fixedly installed inside the lock body cavity, and a keyhole is arranged at the front left end of the lock body, the keyhole passes through the inner rear end of a key hole slot arranged at the front right end of the shell, the middle part of the left end of the key hole slot is connected with a linkage cavity arranged at the inner left end of the shell, the linkage cavity is a "convex" shaped structure, the linkage cavity is connected with a handle slot arranged at the front left end of the shell, a fixed shaft is vertically fixedly installed at the inner left end of the handle slot, a hidden plate two is rotatably installed on the outer side of the fixed shaft, a linkage mechanism is arranged on the rear side of the hidden plate two, and the hidden plate two is connected with a lock hole hidden component arranged at the connection point between the key hole slot and the linkage cavity through the linkage mechanism.

[0006] As a preferred technical solution of the utility model, the keyhole hiding assembly is composed of a hidden plate 1, a pulley, a connecting shaft and a track. The hidden plate 1 is a "U"-shaped plate. The left and right ends of the upper and lower sides of the hidden plate 1 are rotatably installed with pulleys. The pulleys are slidably installed in the tracks set on the upper and lower sides of the connection between the keyhole slot and the linkage cavity. The left end of the rear side of the hidden plate 1 is fixedly installed with a connecting shaft. The "U"-shaped structure of the hidden plate 1 is not only convenient for hiding the keyhole, but also realizes the hiding and exposure of the keyhole through the sliding of the pulley in the track. At the same time, the setting of the connecting shaft enables the hidden plate 1 to be effectively connected with the linkage mechanism to realize linkage operation, thereby improving the convenience of use.

[0007] The cam is an axially movable member connected to the guide rail of the present invention, wherein the cam is provided with a plurality of movable members, the movable members having the plurality of movable members being connected to the guide rails and the plurality of movable members being connected to the plurality of movable members. Through the design of the slide rail, push block one can slide smoothly along it, and through the connection between the connecting rod and the connecting shaft, the hidden plate one can be driven to move. At the same time, the setting of the compression spring ensures that push block one can automatically return to its original position when not affected by external force, thereby realizing automatic hiding of the keyhole. In addition, the active contact between push block one and push block two allows hidden plate one to move with the movement of hidden plate two, and at the same time, hidden plate two "blocks" the handle groove, thereby realizing the hiding function of the handle groove.

[0008] As a preferred technical solution of the utility model, a blocking groove is provided at the rear right side of the handle groove, and the blocking groove blocks the extension plate provided at the rear right side of the second hidden plate. The blocking groove blocks the extension plate provided at the rear right side of the second hidden plate, so that when the push block 1 is reset, the push block 2 is prevented from pushing the second hidden plate out of the handle groove, thereby ensuring the hiding function of the handle groove.

[0009] As a preferred technical solution of the utility model, it also includes a contact roller, which is rotatably installed in a groove set at the right end of the front side of the push block 1, and the outer surface of the contact roller is in active contact with the left surface of the push block 2 and the rear surface of the hidden plate 2. The design of the contact roller makes the contact between the push block 1 and the push block 2 and the hidden plate 2 smoother, reduces friction and wear, and increases the service life.

[0010] As a preferred technical solution of the utility model, it also includes mounting ears, which are provided in two groups, and the mounting ears are respectively welded and arranged on the upper and lower sides of the shell in a left-right symmetrical manner, and the middle of the mounting ears are respectively provided with mounting holes. The arrangement of the mounting ears facilitates the installation and fixing of the door lock.

[0011] Beneficial effects of the utility model: the utility model can trigger the hiding mechanism by pushing the hidden plate 2 into the handle groove. During the pushing process, the push block 2 on the rear side of the hidden plate 2 comes into contact with the push block 1 and pushes it to slide on the slide rail. The push block 1 is cleverly connected with the connecting shaft through the connecting rod, thereby driving the hidden plate 1 to slide smoothly in the track through the pulley. This series of actions enables the hidden plate 1 to move from the keyhole groove to the linkage cavity, thereby smoothly exposing the keyhole for the user to insert the key to unlock or lock the lock.

[0012] When the user completes the unlocking or locking action, no additional operation is required. Under the automatic rebound force of the compression spring, the push block 1 smoothly returns to the initial position along the slide rail. As the push block 1 moves, the hidden plate 1 will also slide back into the keyhole slot to hide the keyhole again, ensuring the neatness and beauty of the door lock. In addition, the hidden plate 1 can move with the movement of the hidden plate 2, and the hidden plate 2 "blocks" the handle slot, thereby realizing the hiding function of the handle slot;

[0013] In summary, the door lock with hidden keyhole is simple to operate and easy to use. The hiding and exposure of the keyhole are achieved through the linkage design of hidden plate one and hidden plate two. In addition, hidden plate two "blocks" the handle groove, thereby realizing the hiding function of the handle groove and improving the safety and aesthetics of the door lock.
