[0035] Hereinafter, exemplary embodiments of the present utility model will be described in more detail with reference to the accompanying drawings. Although the exemplary embodiments of the present utility model are shown in the drawings, it should be understood that the present utility model can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that one can more thoroughly understand the present utility model and fully convey the scope of the present utility model to those skilled in the art.

[0036] As Figures 1 to 5 shown, an embodiment of the present utility model provides a mechanical lock that is easy to install, including: two fixing plates 1; an operating mechanism 2, disposed on the surface of the fixing plate 1 to control the rotation of the lock core; a door lock mechanism 3, disposed between the two fixing plates 1 to lock and unlock the door panel; an auxiliary installation mechanism 4, disposed on the surface of the fixing plate 1 to facilitate the installation of the door lock by the staff. As Figures 1 to 5As shown in the figure, the operating mechanism 2 includes a rotating block 22 which is rotatably connected to the fixed plate 1. A door handle 21 is fixedly connected to the surface of the rotating block 22. Fixed bolts 25 are fixedly installed on the inner walls of the two fixed plates 1. When closing the door, the spring in the lock core box 31 automatically extends and contracts, driving the bolt 34 to be inserted into the card slot in the door frame. The user can insert the key 32 into the lock core box 31 and rotate the key 32 to control the lock pin 35 to be inserted into the card slot in the door frame to lock the door panel. Reversing the key 32 can retract the lock pin 35. When the user rotates the door handle 21, it drives the rotating block 22 and the rotating column 33 to rotate. At this time, the torsion spring 23 is in a compressed state. After the door handle 21 is pressed down, the bolt 34 retracts, and the door panel can be rotated open. The door lock mechanism 3 includes a lock core box 31 which is located between the two fixed plates 1 and fixedly installed. A rotating column 33 is rotatably connected to the inner wall of the lock core box 31. The rotating column 33 is engaged with the rotating block 22. A bolt 34 is fixedly installed on the inner wall of the lock core box 31. A key 32 is engaged with the inner wall of the lock core box 31. A lock pin 35 is fixedly installed on the inner wall of the lock core box 31. A fixed bracket 24 is fixedly connected to the inner wall of the fixed plate 1. A torsion spring 23 is sleeved on the arc surface of the rotating block 22. The torsion spring 23 is fixedly connected to the fixed bracket 24, and the other end of the torsion spring 23 is fixedly connected to the rotating block 22. Releasing the door handle 21, the torsion spring 23 drives the door handle 21 to

[0037] automatically reset. The auxiliary installation mechanism 4 includes a rubber strip 41 which is adhesively bonded to the fixed plate 1. A thin film sheet 43 is adhesively bonded to the surface of the rubber strip 41. When installing the door lock on the door panel, the staff tears off the thin film on the rubber strip 41, and then the staff pastes the fixed plate 1 on the door panel. The rubber strip 41 makes the fixed plate 1 adsorbed on the door panel. Then, the fixed plate 1 on the other side of the door panel is also adhered to the door panel. Then, the fixed bolt 25 is passed through the two fixed plates 1 and tightened, and the door lock is fixedly installed on the door panel. A sealing strip 42 is fixedly connected to the inner wall of the fixed plate 1. The sealing strip 42 is made of silica gel. A pinch piece 44 is fixedly connected to the surface of the thin film. The staff pinches the pinch piece 44, and the surface of the pinch piece 44 is frosted.

[0038] In the embodiment of the present invention, when installing the door lock on the door panel, the staff pinches the pinch piece 44 to tear off the thin film on the rubber strip 41. Then, the staff pastes the fixed plate 1 on the door panel. The rubber strip 41 makes the fixed plate 1 adsorbed on the door panel. Then, the fixed plate 1 on the other side of the door panel is also adhered to the door panel. Then, the fixed bolt 25 is passed through the two fixed plates 1 and tightened, and the door lock is fixedly installed on the door panel.

[0039] When the door is closed, the spring inside the lock core box 31 automatically extends and contracts, driving the bolt 34 to insert into the slot in the door frame. The user can insert the key 32 into the lock core box 31 and turn the key 32 to control the lock pin 35 to insert into the slot in the door frame to lock the door panel. Turning the key 32 in reverse can retract the lock pin 35. When the user turns the door handle 21, it drives the rotating block 22 and the rotating column 33 to rotate. At this time, the torsion spring 23 is in a compressed state. After the door handle 21 is pressed down, the bolt 34 retracts, and the door panel can be rotated open. Releasing the door handle 21, the torsion spring 23 drives the door handle 21 to automatically reset.

[0040] The above is the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
