DETAILED DESCRIPTION

[0016] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0017] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings, wherein the same parts are represented by the same reference numerals.

[0018] It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to directions in the drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0019] In order to make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0020] Combined with Figure 1 -Attached Figure 3 A compression cabinet lock comprises a lock body 1, a lock core 2 is arranged inside the lock body 1, the lock core 2 comprises a rotating shaft 3 which passes through the middle of the lock body 1, the rotating shaft 3 is movably connected to the lock body 1, a key inserting portion 4 is arranged at the front end of the rotating shaft 3, and a lock strike plate 5 is connected to the rear end of the rotating shaft 3.

[0021] In one embodiment, a first installation cavity 6 and a second installation cavity 8 are provided inside the lock body 1, the first installation cavity 6 is connected to the second installation cavity 8 and the inner diameter of the second installation cavity 8 is smaller than the inner diameter of the first installation cavity 6, the rotating shaft 3 includes a rotating shaft body 9 and a lock core head 10 arranged at the front end of the rotating shaft body 9, the lock core head 10 is movably arranged inside the first installation cavity 6, the rotating shaft body 9 sequentially passes through the first installation cavity 6 and the second installation cavity 8 and is movably connected with the second installation cavity 8, and the rotating shaft body 9 is sleeved with a spring 11 located in the first installation cavity 6. In this embodiment, the pressing and rotating mechanism between the rotating shaft 3 and the lock body 1 is particularly emphasized. This mechanism enables the rotating shaft 3 (specifically the rotating shaft body 9) to be pressed first and then rotated when the user inserts the key through the key insertion part 4 and presses the lock core 2 inward. After the rotation is completed, due to the restoring force of the spring 11, the lock plate 5 can automatically lock the cabinet door. Specifically, a first mounting cavity 6 and a second mounting cavity 8 are provided inside the lock body 1, and the two are connected and the inner diameter of the second mounting cavity 8 is smaller than the inner diameter of the first mounting cavity 6. Such a design is to ensure that the rotating shaft 3 (including the rotating shaft body 9 and the lock core head 10) can be stably installed therein and allow it to move and rotate as necessary. The rotating shaft body 9 passes through the first mounting cavity 6 and the second mounting cavity 8, and a spring 11 is sleeved in the first mounting cavity 6. When the user inserts the key into the key insertion part 4 and presses inward, the lock core head 10 and the rotating shaft body 9 will be pressed, and the spring 11 will be driven into a compressed state. At this time, the guide pin 14 (located on the rotating shaft body 9) will slide along the guide notch 13 (located on the inner end surface circumference of the lock body 1) until it reaches a predetermined position, allowing the rotating shaft body 9 to rotate. When the user rotates the rotating shaft 3 (i.e. the rotating shaft body 9) 90 degrees clockwise with the key, and releases the pressure on the lock core 2, the spring 11 pushes the lock core head 10 and the rotating shaft body 9 back to the original position under the action of the restoring force. During this process, the lock plate 5 (connected to the rear end of the rotating shaft body 9) is in a vertical state and tightly pressed against the edge of the cabinet door, thereby completing the locking operation.

[0022] In one embodiment, one end of the spring 11 is connected to the inner wall of the first installation cavity 6, and the other end of the spring 11 is provided with a connecting ring 12, which is rotatably connected to the lock core head 10. The connecting ring 12 and the lock core head 10 are rotatably connected to ensure that when the rotating shaft 3 moves, the spring 11 can provide stable elastic support and does not hinder the rotation of the lock core head 10.

[0023] In one embodiment, four guide slots 13 are provided on the inner end surface circumference of the lock body 1, and guide pins 14 corresponding to the guide slots 13 are provided on the shaft body 9, and the guide pins 14 are slidably arranged in the guide slots 13. The arrangement of the guide slots 13 and the guide pins 14 facilitates the shaft body 9 to return to its original position along a certain direction after rotation.

[0024] In one embodiment, the key inserting portion 4 is a square protrusion arranged at the front end of the lock core head 10. This shape design allows only a key with a keyhole of a corresponding shape to be inserted and operate the lock, thereby improving the security of the lock.

[0025] In one embodiment, the lock body 1 is provided with a first threaded portion and a fixing nut 15 is threadedly connected to the first threaded portion, and a first gasket 16 is also provided at the front end of the fixing nut 15. In order to increase the friction between the fixing nut 15 and the cabinet door to prevent it from loosening, a first gasket 16 is also provided at the front end of the fixing nut 15. Such a design enables the entire lock to be firmly fixed on the cabinet door.

[0026] In this embodiment, the inner end of the shaft body 9 is provided with a second threaded portion, and two locking nuts 17 are threadedly connected to the second threaded portion. In order to increase the friction between the locking nuts 17 and the shaft body 9 and adjust the position of the locking plate 5, two second washers 7 are provided between the two locking nuts 17. Finally, the locking plate 5 is installed between the two second washers 7, and the stability and reliability of the locking plate 5 can be ensured by adjusting the positions of the two locking nuts 17.

[0027] Working principle: When installing the present application, the lock body 1 is inserted into the cabinet door, and the first gasket 16 is put on from the inside of the cabinet door to fix the entire lock on the cabinet door through the fixing nut 15, and then the lock plate 5 is fixed to the shaft body 9 through two tightening nuts 17. When the cabinet door is locked, the key with a square mouth is inserted into the key insertion part 4, and the lock core 2 is pressed inward. At this time, the spring 11 is gradually in a compressed state. When the guide pin 14 at the inner end of the lock core 2 slides out of the guide pin 14, the guide pin 14 is pressed inward. When the lock core 2 is turned to the slot 13, the entire lock core 2 is rotated by the key. After the lock core 2 is rotated 90 degrees clockwise, the pressure on the lock core 2 is cancelled, and the spring 11 returns to its original state under the action of the elastic force, thereby driving the entire lock core 2 to return to its original position. At this time, since the lock core 2 is instantly rotated 90 degrees, the lock plate 5 is in a vertical state and the lock plate 5 is pressed against the cabinet frame edge under the action of the elastic force of the spring 11. At this time, the cabinet door cannot be pulled outward when it is pulled outward, thereby completing the locking.

[0028] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
