Description

Technical Field

[0001] The invention relates to the technical field of electrical equipment, and in particular to a cabinet drawer locking device. Background Art

[0002] The power electrical cabinet is a cabinet made of steel material used to protect the normal operation of components. Electrical cabinets are widely used and are mainly used in the chemical industry, environmental protection industry, power system, metallurgical system, industry, nuclear power industry, fire safety monitoring, transportation industry and other fields. When used in different occasions, its type is also different. It mainly has two functions: distributing and controlling power to electrical equipment, and providing power-off protection when the circuit is overloaded, short-circuited and leaking. During the use of the electrical cabinet, the drawer in the electrical cabinet needs to be pulled out or reset. The stability of the drawer after reset has an important impact on the subsequent safe use of the electrical cabinet. When relying on the traditional mechanical structure to lock the drawer, the locking effect is not ideal. After long-term use, the drawer is prone to automatic dislocation. Therefore, a cabinet drawer locking device is needed to solve the above problems. Summary of the invention

[0003] In view of the above-mentioned shortcomings of the prior art, an object of the present invention is to provide a cabinet drawer locking device for solving the problem of the stability of the cabinet after the cabinet is reset in the prior art.

[0004] In order to achieve the above-mentioned purpose and other related purposes, the present invention provides the following technical solutions:

[0005] A cabinet drawer locking device comprises a base, guide rails symmetrically arranged on the upper end surface of the base along both ends of the base, support plates arranged on both sides of the base for supporting the guide rails, a locking assembly assembled at the base root and the end of the guide rails, and a base connecting seat arranged at the base root;

[0006] The locking assembly includes a locking frame arranged at the end of the guide rail and arranged on the inner side of the support plate in the horizontal direction. The locking frame and the support plate are spaced apart, and a locking base is arranged between the locking frame and the support plate. A magnetic spring buckle is hinged on the locking base. The locking base is an electromagnetic base, and a power cord of an external power supply is connected to the rear end of the locking base. The opening end between the magnetic spring buckle and the locking base is arranged toward the root of the base, and a locking elastic member is arranged between the magnetic spring buckle and the electromagnetic base, near the intersection.

[0007] To implement the above technical solution, the setting of the guide rail can limit the sliding of the drawer in the base, and the support plate provides stable support for the guide rail to ensure the stability of the guide rail in use. The setting of the locking frame can provide a stable working space for the locking base to ensure the stability of the locking base in use. The magnetic snap buckle is hinged on the locking base, and the electromagnetic base of the locking base is powered on or off to achieve a magnetic attraction effect, so that the magnetic snap buckle can be adsorbed on the locking base. When the magnetic snap buckle does not need to be adsorbed on the locking base, the locking elastic member will lift the magnetic snap buckle to a certain height. When the drawer comes in, the magnetic snap buckle can be pressed on the locking base by the drawer's own pressure, which is convenient for the drawer to enter. When the drawer enters and is locked, the locking elastic member can be used to bounce the magnetic snap buckle to prevent the drawer from falling off. When the drawer needs to be pulled out, power is turned on to make the electromagnetic base of the locking base produce a magnetic attraction effect, so that the magnetic snap buckle can be adsorbed on the locking base, which is convenient for the drawer to be pulled out.

[0008] In one embodiment of the present invention, a locking arc piece is provided at one end of the magnetic snap buckle away from the hinge point, and an opening end of the locking arc piece is arranged toward the upper end surface of the electromagnetic base.

[0009] To implement the above technical solution, the setting of the locking arc piece can play a guiding role when the drawer is put into place, and when the drawer is in place, it can achieve a limiting effect on the drawer to prevent it from falling off the base.

[0010] In one embodiment of the present invention, the horizontal height of the upper end surface of the electromagnetic base is higher than the horizontal height of the upper end surface of the support plate.

[0011] The implementation of the above technical solution can facilitate the locking of the drawer in conjunction with the locking arc piece.

[0012] In one embodiment of the present invention, the locking base is provided with three groups between the locking frame and the support plate along the sliding direction of the drawer.

[0013] By implementing the above technical solution, multiple sets of locking bases can ensure the locking effect of the drawer and prevent the drawer from easily falling off the base.

[0014] In one embodiment of the present invention, the locking base is detachably assembled on the support plate by bolts.

[0015] Implementing the above technical solution facilitates subsequent disassembly and maintenance of the locking base.

[0016] In one embodiment of the present invention, the intersection point between the magnetic snap buckle and the locking base is located at the root of the magnetic snap buckle.

[0017] Implementing the above technical solution can facilitate the installation of the locking elastic member.

[0018] As described above, a cabinet drawer locking device of the present invention has the following beneficial effects:

[0019] 1. The setting of the guide rail can limit the sliding of the drawer in the base, while the support plate provides stable support for the guide rail to ensure the stability of the guide rail.

[0020] 2. The magnetic snap buckle is hinged on the locking base, and the electromagnetic base of the locking base is powered on or off to achieve a magnetic attraction effect, so that the magnetic snap buckle can be adsorbed on the locking base.

[0021] 3. When the magnetic snap buckle does not need to be adsorbed on the locking base, the locking elastic part will lift the magnetic snap buckle to a certain height. When the drawer comes in, the drawer's own pressure can press the magnetic snap buckle on the locking base to facilitate the entry of the drawer. When the drawer is entered and locked, the locking elastic part can be used to bounce the magnetic snap buckle to prevent the drawer from falling off.

[0022] 4. When the drawer needs to be pulled out, power is turned on to make the electromagnetic base of the locking base produce a magnetic attraction effect, so that the magnetic snap buckle can be adsorbed on the locking base, thereby facilitating the pulling out of the drawer.
