Description

Technical Field

[0001] The utility model belongs to the technical field of power distribution cabinets, and in particular relates to a power distribution cabinet capable of preventing a cabinet door from tilting. Background Art

[0002] The conventional width of traditional distribution cabinets is 600-800mm. For cabinets with a width of 600-800mm, the force on the hinge side of the cabinet door is not large, and the cabinet door is rarely unable to be closed due to tilt. However, due to the increase in power consumption, the capacity of a single transformer is getting larger and larger, resulting in a significant increase in the rated current of the low-voltage switch and the size of the switch. The 800mm wide cabinet cannot accommodate the switch. For example, for a large-capacity transformer of 2500kVA, a low-voltage switch often chooses a switch with a rated current of 5000A. Such a large-current switch often requires a 1000mm wide cabinet, and the width of the cabinet and the cabinet door increases by nearly half. Therefore, the weight of the cabinet door increases significantly. If the cabinet door is installed only by hinges in the previous way, the force points of the entire cabinet door are concentrated on the hinges, resulting in the hinges being severely stressed and easily deformed, and the cabinet door is prone to tilting downward and deforming, which ultimately leads to the door being unable to be closed or locked, exposing the live parts and prone to safety accidents such as electric shock. Utility Model Content

[0003] (I) Purpose of the utility model

[0004] In order to overcome the above shortcomings, the purpose of the utility model is to provide a distribution cabinet that prevents the cabinet door from tilting, so as to solve the technical problem that the existing heavy cabinet door hinges are severely stressed and easily deformed, causing the cabinet door to easily tilt and deform downward, and the cabinet door and the cabinet body cannot cooperate to close and lock.

[0005] (II) Technical solution

[0006] To achieve the above objectives, the technical solutions provided by this application are as follows:

[0007] A power distribution cabinet for preventing a cabinet door from tilting comprises: a cabinet body and a cabinet door, wherein one side of the cabinet body is hingedly connected to the cabinet door through a hinge, and the other side is provided with a support seat, and a support tongue piece matching the height of the support seat is provided at a position on the cabinet door corresponding to the support seat, and can be abutted by the support seat to support the cabinet door when the cabinet door is closed;

[0008] The present application sets a support base and a support tongue. One side of the cabinet body is connected to the cabinet door through a hinge, and a support base is set on the other side. A support tongue is set on the cabinet door. When the cabinet door is closed, the support tongue on the cabinet door just presses on the support base, so that when the cabinet door is closed, in addition to the support of the hinge, the support base also supports the cabinet door through the support tongue, thereby increasing the force on the support point and always supporting the normally closed cabinet door on the same horizontal plane. In this way, the hinge will not be deformed due to excessive force on one side, causing the cabinet door to sag or tilt, and the cabinet door will be severely deformed, permanently fail or even fall off, ultimately resulting in the maintenance personnel being unable to close the cabinet door or lock it, resulting in exposed live parts that are prone to electric shock and other adverse phenomena.

[0009] In some embodiments, a support roller is rotatably provided at the upper end of the support seat, wherein the height of the support roller is higher than the support seat, and can roll under the drive of the support tongue piece during the closing process of the cabinet door, and support the support tongue piece after the door is closed;

[0010] By arranging a support roller on the support seat, the friction generated during the contact between the support tongue and the support seat can be reduced, thereby ensuring smoothness when closing the door and avoiding the problem of deformation and damage caused by long-term contact and wear between the support tongue and the support seat.

[0011] In some embodiments, the supporting tongue piece is a right-angle structure, including: a connecting portion connected to the cabinet door and a force-bearing portion perpendicular to the connecting portion;

[0012] In some embodiments, the end of the force-bearing portion close to the supporting roller is tilted upward to form a guiding inclined surface for guiding the supporting roller to the bottom of the force-bearing portion;

[0013] By setting a guide slope that is tilted upward, the support roller can be guided to the bottom of the force-bearing part, avoiding direct collision between the end of the force-bearing part and the support roller, which may easily cause the support roller to loosen or fall off due to long-term use.

[0014] In some embodiments, a long waist-shaped adjustment hole for adjusting the installation height of the support base is vertically opened on the support base;

[0015] Since the openings on the cabinet door frame are opened at fixed intervals, a waist-shaped adjustment hole is opened on the support base so that the position of the support base can be moved up and down to match the support base with the hinge height on one side.
