[0032] See attached document Figures 1 to 9 This utility model provides a more detailed description of a cabinet door lock.

[0033] A cabinet door lock includes a latch box 1 with a built-in first magnet, a locking component 2, and an unlocking component 3, wherein the latch box 1 is installed on the top plate 5 of the storage cabinet, and the locking component 2 and the unlocking component 3 are installed on the cabinet door 6; the locking component 2 includes a mounting base 21 and a locking hook 22 slidably disposed on the mounting base 21, and the first magnet causes the locking hook 22 to engage with the latch box 1;

[0034] The unlocking component 3 includes a housing 31, an unlocking button 32 slidably disposed on the housing 31, a button reset spring 33, and an unlocking linkage 34. One end of the button reset spring 33 abuts against the housing 31, and the other end abuts against the lower end of the unlocking button 32.

[0035] One end of the unlocking linkage 34 is slidably disposed above the lock hook 22, and the other end extends downward to connect with the unlocking button 32; when the unlocking button 32 is pressed, the unlocking button 32 drives the unlocking linkage 34 to separate the lock hook 22 from the buckle box 1 and compresses the button reset spring 33.

[0036] When the cabinet door 6 is closed, and the locking hook 22 is opposite to the latch box 1, the magnetic attraction of the first magnet inside the latch box 1 causes the locking hook 22 to slide upward. The locking hook 22 is inserted into the latch box 1, locking the cabinet door to the cabinet body and realizing the automatic locking of the cabinet door.

[0037] Pressing down the unlock button 32 causes the lock hook 22 to overcome the magnetic attraction of the first magnet and slide downwards, separating from the latch box 1, via the unlocking linkage 34, thus unlocking the cabinet door 6 and opening it. The unlocking operation is easy and convenient. Releasing the unlock button 32 causes it to slide upwards under the action of the button reset spring 33, achieving automatic reset. This solves the problem that existing ordinary door locks cannot be used on cabinet doors 6. At the same time, the cabinet door lock has a simple structure, saving on cabinet door lock production costs.

[0038] The mounting base 21 is equipped with an unlocking spring 211. One end of the unlocking spring 211 abuts against the upper end of the lock hook 22, and the other end abuts against the lower end of the unlocking linkage 34. When the unlocking button 32 is pressed down, the unlocking button 32 drives the unlocking linkage 34, causing the unlocking linkage 34 to press down on the unlocking spring 211. The unlocking spring 211 drives the lock hook 22 to slide downward, thereby unlocking. When the unlocking button 32 is released, the unlocking spring 211 pushes the unlocking linkage 34 upward, thereby resetting the unlocking linkage 34. The unlocking linkage 34 includes an unlocking post 341 at the upper end and a steel wire rope 342 at the lower end. The upper end of the steel wire rope 342 is connected to the unlocking post 341, and its lower end is connected to the unlocking button 32. The unlocking button 32 pulls the unlocking post 341 downward through the steel wire rope 342.

[0039] The locking hook 22 has a built-in second magnet that attracts the first magnet. When the locking hook 22 is opposite to the buckle box 1, the second magnet cooperates with the first magnet to pull the locking hook 22 into the buckle box 1, so that the first magnet has a stronger attraction to the locking hook 22.

[0040] The housing 31 is rotatably equipped with a deadbolt 4. The deadbolt 4 has a semi-circular deadbolt protrusion 41 on its end face and a hexagonal socket 42 on its end face. When deadbolt is required, the deadbolt 4 is rotated by inserting a hexagonal screwdriver into the hexagonal socket 42. Rotating the deadbolt 4 by 90 degrees causes the deadbolt 41 to abut against the unlock button 32, preventing the unlock button 32 from sliding and thus achieving deadbolt. Rotating the deadbolt 4 by 90 degrees in the opposite direction separates the deadbolt 41 from the unlock button 32, thus releasing the deadbolt.

[0041] The lock hook 22 includes a hook body 221 and a hook seat 222. The hook seat 222 has a through hole 2221 for the steel wire rope 342 to pass through, and the second magnet is placed inside the hook body 221. The mounting base 21 has a vertically arranged mounting groove 212, and the unlocking pin 341 and the hook seat 222 are slidably disposed in the mounting groove 212. This allows the unlocking pin 341 and the hook seat 222 to slide more stably in the vertical direction, thereby improving the structural stability of the cabinet door lock.

[0042] The housing 31 includes a bottom shell 311 and a top cover 312. The bottom shell 311 is provided with a groove 3111 for the unlock button 32 to slide, so that the unlock button 32 can slide smoothly on the housing 31. The lower end of the unlock button 32 passes through the groove 3111 and is connected to the wire rope 342, which facilitates the installation of the unlock button 32 and the wire rope 342.

[0043] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
