[0006] The elastic fixing mechanism includes several cross slots equidistantly arranged on the busbar, four locking bars that are elastically slidably disposed in the cross slots by springs, and a control rod that passes through the busbar to control the synchronous movement of the four locking bars; when the spring is in the normal state, the locking bars are locked in the slots, and when the spring is in the contracted state, the locking bars are outside the slots.

[0007] As an improvement, the cabinet includes a cabinet bottom, support plates set on both sides of the middle of the upper part of the cabinet bottom, several busbars equidistantly set in the middle of the two support plates, L-shaped mounting plates set at the four corners of the upper part of the cabinet bottom, a top plate set at the upper part of the support plates and mounting plates, side plates that are installed with screws on the outer side of the two mounting plates on both sides, back plates that are installed with screws on the outer side of the two mounting plates at the rear, and hinged doors on the outer side of the two mounting plates at the front.

[0008] As an improvement, the top panel is located outside the side panels, back panel, and door. The upper part of the side panels is provided with air holes, with a filter screen inside the air holes and a water-blocking strip outside.

[0009] As an improvement, slots are provided around the electrical components;

[0010] The beneficial effects of this utility model are:

[0011] By setting up modular cabinets, the cabinets can be disassembled during maintenance, making it convenient for workers to operate. By setting up flexible fixing mechanisms to secure electrical components, the electrical components can be quickly removed. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] according to Figure 1—5 shows: This utility model provides a power distribution cabinet that is easy to maintain and debug: including a base 1; an assembled cabinet 2 is provided above the base 1; the cabinet 2 includes a cabinet bottom 201, support plates 202 set on both sides of the middle of the upper part of the cabinet bottom 201, a plurality of busbars 203 equidistantly arranged in the middle of the two support plates 202, L-shaped mounting plates 204 set at the four corners of the upper part of the cabinet bottom 201, a top plate 205 set on the upper end of the support plates 202 and the mounting plates 204, side plates 207 installed with screws 206 on the outer side of the two side mounting plates 204, a back plate 208 installed with screws 206 on the outer side of the two rear mounting plates 204, and a front plate 208. Hinged doors 209 are provided on the outer sides of the two mounting plates 204; the top plate 205 is located outside the side plates 207, back plate 208, and doors 209. The upper part of the side plate 207 is provided with air holes, with a filter screen 2071 inside the air holes and a water-retaining strip 2072 on the outside; the parts where the top plate 205, side plates 207, back plate 208, and doors 209 contact each other are provided with sealing strips. Thus, the side plates 207 and back plates 208 can be removed by removing the screws 206, so that the busbar 203 for installing electrical components 3 is unobstructed, which facilitates workers' operations; the design of the water-retaining strip 2072 can prevent rainwater from entering the device without affecting normal heat dissipation.

[0020] according to Figure 2 , 3 As shown in Figures 4 and 5: The cabinet 2 is equipped with an elastic fixing mechanism 4 for fixing electrical components 3; the electrical components 3 are provided with slots 301 around their perimeter; the elastic fixing mechanism 4 includes several cross slots 401 equidistantly arranged on the busbar 203, four locking strips 403 elastically slidably disposed in the cross slots 401 by springs 402, and a control rod 404 passing through the busbar 203 to control the synchronous movement of the four locking strips 403; when the springs 402 are in the normal state, the locking strips 403 are locked in the slots 301, and when the springs 402 are in the contracted state, the locking strips 403 are outside the slots 301; thus, by pushing the control rod 404, the four locking strips 403 can be moved outward, and then the electrical components 3 are placed in the middle of the four locking strips 403. Then, the control rod 404 is released, and the springs 402 will push the locking strips 403 to move, so that the locking strips 403 are locked in the slots 301, and at the same time, the control rod 404 is pushed outward. Thus, the installation and removal of electrical components 3 is convenient and quick.

[0021] The principle of this utility model is as follows: In use, first, place the base 1 in the desired position, then push the control lever 404 to move the four locking strips 403 outwards. Next, place the electrical component 3 in the middle of the four locking strips 403, and then release the control lever 404. The spring 402 will push the locking strips 403 to move, so that the locking strips 403 are locked in the slots 301. At the same time, it will push the control lever 404 outwards, thus installing the electrical component 3. Then, connect the wiring of the electrical component 3. After the electrical component 3 is set up, use screws 206 to secure the back plate 2. 08. The side panel 207 is installed on the mounting plate 204, and the device is set up. During normal use, the vents can support the normal heat dissipation of the electrical component 3. The design of the water baffle 2072 can prevent rainwater from entering the device without affecting normal heat dissipation. During routine maintenance, the door 209 can be opened. When a major overhaul is required, the cabinet 2 is disassembled, so that the busbar 203 for installing the electrical component 3 is unobstructed, which facilitates the operation of workers. When it is necessary to remove the electrical component 3, the control lever 404 can be pressed directly to quickly remove the electrical component 3.

[0022] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
