Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, and in particular to a power distribution cabinet and its door panel support device. Background Technology

[0002] Distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets, and are the final stage equipment in the power distribution system. During prolonged use, existing distribution cabinets may experience door sagging due to gravity, rough handling during transportation, or forceful opening and closing, all of which damage the cabinet doors and prevent them from being opened for maintenance. To address these issues, two main approaches are currently employed. One approach involves using thicker sheet metal panels for the door, requiring additional hinges and reinforcing ribs. This increases the cost of the door panel and has limited effectiveness, as the panel still sags during transport. The other approach uses a rigid fixing mechanism, which secures the door in place after sealing the transformer. However, this method is problematic on uneven surfaces. If the rigid fixing mechanism is positioned on a raised or recessed area, it increases the deformation of the door panel, causing it to become tightly interlocked with the panel. Furthermore, installing the rigid fixing mechanism requires drilling, and disassembly is necessary upon arrival at the site. This reduces the transformer's protection rating, and disassembly is inconvenient and labor-intensive if the door panel is too tall. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art. This utility model provides a power distribution cabinet and its door panel support device, which has a simple structure, occupies little space, and can effectively prevent the cabinet door from sagging.

[0004] To solve the above problems, this utility model proposes a door panel support device for a power distribution cabinet, including a mounting plate, a sleeve, a support rod, an elastic element, and rollers;

[0005] The support rod passes through the sleeve and is fixedly connected to the roller. The support rod and the sleeve can slide relative to each other. The sleeve is provided with the elastic element, which can prevent the roller from approaching the sleeve. The end of the sleeve away from the support rod is fixedly connected to the mounting plate, which is located at the bottom of the door panel of the power distribution cabinet.

[0006] As an improvement to the above technical solution, the elastic element is disposed inside the sleeve, one end of the elastic element abuts or is fixedly connected to the support rod, and the other end abuts or is fixedly connected to the end of the sleeve.

[0007] As an improvement to the above technical solution, the elastic element is a compression spring.

[0008] As an improvement to the above technical solution, the inner wall of the sleeve is provided with ball bearings.

[0009] As an improvement to the above technical solution, a fixing plate is provided vertically on one side of the mounting plate. The fixing plate is fixedly connected to the power distribution cabinet. The mounting plate is located below the door panel, and the roller abuts against the bottom of the door panel.

[0010] As an improvement to the above technical solution, the mounting plate and the fixing plate are integrally formed.

[0011] As an improvement to the above technical solution, the side wall of the support rod is provided with a guide portion, and the inner wall of the sleeve is provided with a guide groove that matches the guide portion, and the guide portion is slidably connected to the guide groove.

[0012] Accordingly, this utility model also provides a power distribution cabinet, including the door panel support device described in the above technical solution.

[0013] The following are the beneficial effects of implementing this utility model:

[0014] This utility model discloses a door panel support device located at the bottom of the door panel of a power distribution cabinet. It includes a mounting plate, a sleeve, a support rod, an elastic element, and rollers. The support rod passes through the sleeve, and the sleeve has an elastic element to prevent the rollers on the support rod from approaching the sleeve. The cooperation of the support rod, sleeve, and elastic element provides support for the door panel during operation, while the friction between the rollers and the contact surface is rolling friction, ensuring smooth opening and closing of the door panel. This simple and easy-to-assemble / disassemble door panel support device is convenient to manufacture and easy to maintain. Attached Figure Description

[0019] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0020] See Figure 1 , Figure 3 and Figure 4 This utility model embodiment provides a door panel support device for a power distribution cabinet, including a mounting plate 5, a sleeve 2, a support rod 4, an elastic element 4, and a roller 3.

[0021] This utility model embodiment provides a support device at the bottom of the distribution cabinet door, so that the door is always subjected to an upward pushing force when closed, thereby preventing the door from sagging.

[0022] Specifically, the support rod 1 passes through the sleeve 2 and is fixedly connected to the roller 3. The support rod 1 and the sleeve 2 can slide relative to each other. The sleeve 2 is provided with the elastic element 4, which can prevent the roller 3 from approaching the sleeve 2. The end of the sleeve 2 away from the support rod 1 is fixedly connected to the mounting plate 5, which is located at the bottom of the door panel of the power distribution cabinet.

[0023] Preferably, the elastic element 4 is disposed inside the sleeve 2, with one end of the elastic element 4 abutting or fixedly connected to the support rod 1, and the other end abutting or fixedly connected to the end of the sleeve 2. The elastic element inside the sleeve 2 ensures that the support rod 1, when compressed, always experiences a resistance that prevents it from moving towards the sleeve 2, thereby applying a pushing force to the door panel of the distribution cabinet.

[0024] Ideally, the elastic element 4 is a compression spring.

[0025] Preferably, the inner wall of the sleeve 2 is provided with ball bearings. The ball bearings inside the sleeve 2 ensure smooth sliding between the sleeve 2 and the support rod 1.

[0026] See Figure 2 As shown in another embodiment of the present invention, a fixing plate 6 is vertically provided on one side of the mounting plate 5. The fixing plate 6 is fixedly connected to the power distribution cabinet. The mounting plate 5 is located below the door panel, and the roller 3 abuts against the bottom of the door panel.

[0027] Preferably, the mounting plate 5 and the fixing plate 6 are integrally formed. The mounting plate 5 and the fixing plate 6 can improve the overall structural strength of the support device.

[0028] Preferably, the side wall of the support rod 1 is provided with a guide portion 11, and the inner wall of the sleeve 2 is provided with a guide groove 21 that matches the guide portion 11. The guide portion 11 and the guide groove 21 are slidably connected. The cooperation between the guide portion and the guide groove 21 can effectively prevent jamming when the sleeve 2 and the support rod 1 slide relative to each other.

[0029] Accordingly, this utility model embodiment also provides a power distribution cabinet, including the door panel support device described above.

[0030] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
