Description

Technical Field

[0001] The utility model belongs to the field of intelligent door locks, and particularly relates to an embedded intelligent door lock with an anti-prying function. Background Art

[0002] In the field of intelligent door locks, there are generally two solutions: embedded and non-embedded. Among embedded door locks, one is to directly integrate with the entire door to form an intelligent door. The door lock mechanism on this intelligent door is completely designed inside the door and integrated with the door, without an exposed lock body, making it difficult to pry open. However, this requires users to directly replace the entire door, and the cost is relatively much higher. The other is to ream a hole in the existing door to install an embedded intelligent lock. For this type of embedded replacement of the original door, a part of the lock body will also be exposed outside the door, and there is also a risk of being violently pried open. Since most of the lock body is embedded in the door, only a circle around the lock body is in contact with the door, and a anti-prying switch cannot be arranged on this circle, nor is there a corresponding surface in contact with the part embedded in the door. Therefore, the embedded door locks in the prior art basically do not have an anti-prying function. Content of the Utility Model

[0003] The purpose of the utility model is to solve the problem that the embedded door locks in the prior art basically do not have an anti-prying function.

[0004] To achieve the above purpose, the utility model provides the following technical solution: an embedded intelligent door lock with an anti-prying function, including a lock body, a pressing plate, an elastic member, a screw, a sealing plate, a push-button alarm switch and a control main board; an installation cavity is arranged inside the lock body, the push-button alarm switch and the control main board are arranged in the installation cavity, the pressing plate includes a plurality of bending surfaces, and the first bending surface covers the push-button alarm switch. The pressing plate is elastically connected with the sealing plate through the elastic member and the screw. The sealing plate closes the pressing plate in the installation cavity by pressing, and at this time, the first bending surface keeps in a pressing state with the push-button alarm switch. When the intelligent door lock is pried open, the sealing plate cannot close the installation cavity. At this time, the elastic member pops open the pressing plate so that the first bending surface cannot keep in a pressing state with the push-button alarm switch, and the push-button alarm switch sends out an alarm through the control main board.

[0005] Preferably, the elastic member is a conical spring.

[0006] Preferably, a door gasket is sleeved around the lock body.

[0007] Preferably, the screw is a screw with a washer, and the sealing plate closes the installation cavity through the cooperation of the screw with a washer and a riveting stud.

[0008] Preferably, the pressing plate is further provided with a second bending surface and a third bending surface that can abut against the door gasket. When the sealing plate closes the installation cavity, the second bending surface and the third bending surface are in a state of abutting against the door gasket.

[0009] Preferably, the pressing plate further includes a fourth bending surface.

[0010] Preferably, when the sealing plate closes the installation cavity, the fourth bending surface is located inside the installation cavity.

[0011] The utility model has the following beneficial effects: By arranging a pressing plate above the lock body in the utility model, when the lock body is installed on the door, the pressing plate surface contacts the door body, and when a downward force is applied, the pressing plate contact surface on the pressing type alarm switch is pressed down, pressing the pressing type alarm switch down to the stroke in the open state. When there is an action of prying open the door lock, under the action of the pressing type alarm switch and the elastic member on the other side, the pressing plate no longer presses the pressing type alarm switch, and the pressing type alarm switch pops up under the action of the internal elastic member, triggering an alarm, realizing the anti-pry alarm function of the embedded door lock. In the utility model, a pressing plate is arranged directly above the pressing type alarm switch, without occupying the space between the lock body and the door body, and there is almost no additional requirement for the installation space of the door body. Therefore, it is more suitable for replacing the original door with an embedded intelligent door lock product with an anti-pry alarm function. Description of the Drawings
