The guide member 600 includes a main body portion 620 that is shaped to fit the movable member 200. The movable member 200 is slidably disposed on the main body 620. The arrangement ensures the aesthetic property of the whole structure of the cabinet door lock and facilitates the installation of the movable part 200 on the main body part 620.

Furthermore, the main body 620 is further provided with a relief hole 640 penetrating through the main body 620 in a region corresponding to the hole 320, so as to prevent the tooth bud from passing through the hole 320 and rubbing against the main body 620, thereby ensuring the normal rotation of the gear portion 310.

In addition, the guide 600 further includes a mounting portion 630 coupled to the main body portion 620 for coupling with the cabinet 500. During installation, the installation portion 630 can be fixed on the corresponding side wall of the cabinet 500 by bolts or welding, and the guide member 600 and the cabinet 500 can be fixed, so that the bolts installed on the main body portion 620 can be prevented from affecting the normal movement of the movable member 200.

Further, the mounting portion 630 is divided into two portions spaced apart from each other to form a mounting area for mounting the lock body 100.

Referring to fig. 1 to 3, in the above embodiments, the hook-shaped latch 400 is an L-shaped structure, one side plate is connected to the movable element 200, the other side plate extends along the first direction a, and a side surface of the side plate, opposite to the movable element 200, is an inclined surface. The inclined plane can guide the hook-shaped bolt 400 to smoothly insert into parts such as a clamping ring, a clamping groove and the like, so that the stability of the service performance of the cabinet door lock is guaranteed.

Referring to fig. 4 to 6, in another embodiment of the present invention, a cabinet 500 is provided, which includes a cabinet body 510 and a cabinet door 520, and further includes a cabinet door lock installed on the cabinet body 510, and a clamping structure 900 formed on the cabinet door 520 and used for clamping and matching with the hook-shaped bolt 400. The clamping structure 900 in this embodiment is a snap ring, a slot, or the like.

Specifically, the cabinet door lock has a plurality of installation manners, one embodiment of which is shown in fig. 4 and 5, an operation opening 514 and a through hole 513 for the hook-shaped bolt 400 to extend are formed on a first side wall 511 of the cabinet body 510, the cabinet door 520 is rotatably installed on the side wall, and an inner side wall of the cabinet door is attached to an outer wall of the side wall in a closed state of the cabinet door 520 to close the operation opening 514. In this case, the lock body 100 is installed on the second sidewall 512 adjacent to the first sidewall 511, the guide 600 is installed at the corner between the first sidewall 511 and the second sidewall 512, and the hook bolt 400 passes through the through hole 513 and extends outward perpendicular to the first sidewall 511. Of course, the installation mode of the cabinet door lock is not limited to the mode shown in fig. 1, and other modes can be adopted, and the installation mode can be specifically set according to the use requirement or the cabinet structure, and is not limited here.
