[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1-Figure 3 The utility model provides an embodiment: a side panel of a distribution cabinet and a distribution cabinet, comprising a distribution cabinet 1, the inner side wall of the distribution cabinet 1 is fixedly connected with a positioning plate 2, the positioning plate 2 can make the outer wall of the side door 3 fit with it, so that the side door 3 will not be folded outward when blocked, and the outer wall of the positioning plate 2 is in contact with the side door 3, which plays the role of enclosing and protecting the electrical equipment inside the distribution cabinet 1 to prevent damage or pollution to the equipment by foreign objects, dust, moisture, etc. The side door 3 is provided with two groups, and the two groups of side doors 3 are hinged to each other by hinges 4. The hinge 4 is a prior art, which can make the side door 3 foldable and easy to place or transport. The inner wall of the right end of the side door 3 is elastically connected to the limiting block 6 by a reset spring 5. The limiting block 6 is an inclined surface. When squeezed, the limiting block 6 can slide along the inner wall of the side door 3. The inner side wall of the distribution cabinet 1 is provided with a limiting groove 7, and the side wall of the distribution cabinet 1 is provided with a shielding mechanism.

[0032] Reference Figure 4-Figure 6A ventilation box 9 is fixedly connected to the top of the distribution cabinet 1. The middle part of the ventilation box 9 is through, so that air can be exchanged through the fan 14. The inner wall of the top of the ventilation box 9 is elastically connected to a moving block 11 through a positioning spring 10. A filter frame 12 is inserted into the inner wall of the ventilation box 9. A filter screen is provided on the filter frame 12. Dust and impurities can be filtered through the filter screen. An L groove 13 is provided on the side wall of the filter frame 12. The L groove 13 has a vertical opening and a horizontal opening. The vertical opening allows the moving block 11 to be connected with it to limit the filter frame 12, and the horizontal opening coincides with the moving block 11, so that the filter frame 12 can be smoothly inserted into the distribution box 1. A fan 14 is provided on the inner wall of the ventilation box 9. The fan 14 passes Driven by an external device, the air in the distribution cabinet 1 can be exchanged with the external air to achieve the effect of heat dissipation. The top inner wall of the ventilation box 9 is fixedly connected to one end of the positioning spring 10. When the moving block 11 moves upward, the positioning spring 10 will be compressed. When resetting, the elastic force of the positioning spring 10 is used to reset the moving block 11. The other end of the positioning spring 10 is fixedly connected to the top of the moving block 11. The moving block 11 penetrates and is slidably connected to the inner wall of the ventilation box 9. There is a block at the sliding position of the moving block 11 of the ventilation box 9, so that the moving block 11 can only move upward to the block, so that the moving block 11 can coincide with the horizontal opening of the L-groove 13 to achieve the positioning effect, and the moving block 11 is clamped with the inner wall of the L-groove 13.

[0033] Reference Figure 1-Figure 3 The inner wall of the right end of the side door 3 is fixedly connected to one end of the return spring 5. When the limit block 6 moves to the right, the return spring 5 will be compressed. When resetting, the elastic force of the return spring 5 is used to reset the limit block 6. The other end of the return spring 5 is fixedly connected to the right end of the limit block 6. The limit block 6 passes through and is slidably connected to the inner wall of the side door 3. The side door 3 has a notch corresponding to the limit block 6, which can allow the limit block 6 to slide along the inner wall of the side door 3. The limit block 6 is plugged into the inner wall of the limit groove 7. The shielding mechanism includes a rotating block 8, which is rotatably connected to the side wall of the distribution cabinet 1. The inner side wall of the rotating block 8 contacts the outer wall of the side door 3, and the side door 3 contacts the inner side wall of the distribution cabinet 1.

[0034] Working principle: first, when the side door 3 needs to be disassembled and assembled, it is only necessary to rotate the rotating block 8 in advance to a horizontal state, and then move the limit block 6 to the right to separate the limit block 6 and the limit groove 7 and compress the reset spring 5, so that one group of side doors 3 can be released from the limit and folded outward, and then the other group of side doors 3 can be released from the limit, and the entire side door 3 can be disassembled and assembled. After the disassembly is completed, the limit block 6 is released and the reverse elastic force of the reset spring 5 is used to reset the limit block 6. The design of the hinge 4 allows the side door 3 to be folded and stored during placement or transportation, reducing the space occupied. When the side door 3 needs to be installed, it is only necessary to fold the two groups of side doors 3 into a vertical state, let the limit block 6 correspond to the limit groove 7, push the side door 3 against the inner side of the distribution cabinet 1, let the side wall of the distribution cabinet 1 squeeze the inclined surface of the limit block 6, let the limit block 6 move to the right and compress the reset spring 5. When the limit block 6 and the inner wall of the limit groove 7 coincide with each other, use the reverse elastic force of the reset spring 5 to reset the limit block 6, let the limit block 6 and the limit groove 7 be plugged into the side door 3 for preliminary limiting, and finally complete the installation by rotating the rotating block 8 into a vertical state to cover the side door 3.

[0035] When the power distribution cabinet 1 is in use, start the fan 14 to allow the outside air to exchange with the air in the power distribution cabinet 1 to reduce moisture and improve its heat dissipation effect. When the filter screen of the filter frame 12 needs to be replaced or cleaned, it is only necessary to move the moving block 11 upwards so that the moving block 11 coincides with the horizontal opening of the L-slot 13 on the filter frame 12. At this time, the filter frame 12 can be moved outward from the ventilation box 9 to clean or replace the filter frame 12. When the filter frame 12 needs to be installed, it is only necessary to insert the filter frame 12 into the ventilation box 9 so that the horizontal opening of the L-slot 13 coincides with the moving block 11. After the filter frame 12 is fully inserted, release the moving block 11 and use the reverse elastic force of the positioning spring 10 to move the moving block 11 downward, so that the moving block 11 is engaged with the vertical opening of the L-slot 13. The filter frame 12 can be limited to complete the disassembly and assembly process of the filter frame 12, which is convenient for replacing and cleaning the filter screen and improving the overall heat dissipation effect.
