Description

Technical Field

[0001] The utility model relates to the technical field of locks, in particular to a lockable cabinet door lock. Background Art

[0002] A distribution cabinet door lock refers to a lock used on a distribution cabinet or distribution box. Most existing distribution cabinets used in the power transmission and distribution field use a rotary door lock between the cabinet door and the cabinet body. The lock tongue rotates with the lock core, thereby being limited between the cabinet door and the cabinet body. Due to the different thicknesses of the cabinet doors of different distribution cabinets, when the existing cabinet door lock is installed on some distribution cabinets with smaller door thicknesses, there is a gap between the lock tongue and the inner side wall of the cabinet door and the cabinet body in the locked state. The cabinet door can be opened outward at this angle relative to the cabinet body, posing a safety hazard. Summary of the Invention

[0003] In view of the deficiencies in the prior art, the utility model provides a cabinet door lock that can be locked.

[0004] The technical solutions provided by this utility model are:

[0005] A lockable cabinet door lock comprises a lock shell, a lock core and a lock tongue. The lock core is arranged in the lock shell, the lock tongue sleeve is arranged at the lower end of the lock core, and the lock tongue is provided with a plurality of step surfaces, which rise step by step along the circumference of the outer side of the lock shell.

[0006] A guiding inclined surface is provided between the adjacent step surfaces.

[0007] The guide inclined surface and the step surface form an angle of 150 degrees.

[0008] The lock tongue is fan-shaped.

[0009] The height differences between the adjacent step surfaces are equal.

[0010] The beneficial effects of the utility model are as follows: the utility model arranges the lock tongue in a step-by-step ascending shape along the circumference of the outer side of the lock shell, and when locking, the lock tongue can be made to fit tightly against the cabinet door and the cabinet body through the number of turns of the lock core rotation, thereby locking the cabinet door. The utility model is suitable for distribution cabinets with cabinet doors of different thicknesses, has good versatility, and can effectively ensure the safety of electrical components or circuit systems in the distribution cabinet. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 This is a schematic structural diagram of an embodiment of the present utility model;

[0012] Figure 2 This is a front view of an embodiment of the utility model;

[0013] Figure 3 This is a schematic diagram of the explosion structure of an embodiment of the utility model. DETAILED DESCRIPTION

[0014] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0015] like Figure 1-3 As shown, a lockable cabinet door lock includes a lock shell 1, a lock core 2, and a lock tongue 3. The lock core 2 is arranged in the lock shell 1. The lock core 2 includes an upper lock core 11 and a lower lock core 12. The upper end of the upper lock core 11 is provided with a linkage portion that is linked to a key, and the lower end is provided with a pop-up portion 12. The upper end of the lower lock core 12 is provided with a groove that is compatible with the pop-up portion 12, and the lower end is provided with a mounting portion 14 for mounting the lock tongue 3. The lock tongue 3 is sleeved on the lower end of the lock core 2, and a mounting hole 15 for mounting the mounting portion 14 is provided in the middle of the lock tongue 3. The lock tongue 3 is fan-shaped, and a plurality of step surfaces 4 are provided on the fan-shaped surface. The step surfaces 4 rise step by step along the circumferential direction of the outer side of the lock shell.

[0016] When locking the cabinet door, the present cabinet door lock inserts the key to squeeze the linkage part, so that the pop-up part 12 pops out and gets stuck in the groove, and the key is turned to drive the upper lock core 11 to rotate. Due to the cooperation between the pop-up part 12 and the groove, the rotation of the upper lock core 11 will drive the lower lock core 12 to rotate, and then drive the lock tongue 3 to rotate. Through the number of rotations of the lock core, the step surface of the lock tongue 3 is pressed against the cabinet door, thereby locking the cabinet door. It is suitable for distribution cabinets with cabinet doors of different thicknesses, has good versatility, and can effectively ensure the safety of electrical components or circuit systems in the distribution cabinet.

[0017] In this embodiment, a guide slope 5 is provided between adjacent step surfaces. Figure 2 As shown, the included angle a formed by the guide bevel 5 and the step surface is 150°. The guide bevel 5 makes the transition between each step surface relatively smooth, which can avoid jamming during the rotation of the lock tongue. Preferably, the height difference between adjacent step surfaces is equal to prevent the step surface from being unable to stick to the cabinet door normally due to excessive drop.

[0018] The embodiments should not be regarded as limiting the present invention, and any non-inventive improvements based on the spirit of the present invention should be regarded as falling within the protection scope of the present invention.
