DETAILED DESCRIPTION

[0021] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0022] according to Figure 1-6As shown, this embodiment proposes a low-voltage power distribution cabinet that is easy to disassemble and assemble, including a cabinet body 1, a cabinet door 2, a handle 3 and a fixing column 4. A mounting seat 5 is provided at the bottom of the cabinet body 1, and a fixing component connected to the fixing column 4 is provided at the bottom of the mounting seat 5. A plurality of groups of first mounting plates 6 are provided inside the cabinet body 1, and a second mounting plate 7 is provided on the front side of the first mounting plate 6. The second mounting plate 7 is clamped with the first mounting plate 6 through a clamping component, and an electrical component 8 is installed on the front side of the second mounting plate 7;

[0023] The snap-in assembly includes a snap-in seat 9, a plug-in rod 10, a roller 11, a slot 12, a first elastic fixing piece and a second elastic fixing piece. The snap-in seat 9 is fixedly connected to the first mounting plate 6, and the plug-in rod 10 is symmetrically arranged on the rear side wall of the second mounting plate 7. The roller 11 is rotatably mounted on the end of the plug-in rod 10. The first elastic fixing piece is symmetrically arranged on the inner wall of the snap-in seat 9, and the second elastic fixing piece is arranged on the rear side of the first elastic fixing piece. The outer wall of the plug-in rod 10 is provided with a slot 12 adapted to the first elastic fixing piece.

[0024] When the device is installing the electrical component 8, the electrical component 8 is first installed on the second mounting plate 7 in the outside, and then the plug-in rod 10 is inserted into the clamping seat 9, and the inserted plug-in rod 10 is limited and locked by the first elastic fixing member and the second elastic fixing member, thereby completing the installation of the electrical component 8. The external installation method avoids the problem of interference with the installation due to the small internal space of the distribution cabinet. At the same time, the plug-in installation method is also more convenient, and it is more convenient in subsequent replacement or disassembly. At the same time, the setting of the first elastic fixing member and the second elastic fixing member greatly increases the stability of the installation of the electrical component 8 by adopting two sets of locking structures.

[0025] The first elastic fixing member includes a first spring telescopic rod 13 and a block 14, one end of the first spring telescopic rod 13 is fixedly connected to the inner wall of the card seat 9, and the other end of the first spring telescopic rod 13 is fixedly connected to the block 14, and the block 14 is semicircular. Through the elastic potential energy of the first spring telescopic rod 13, when the roller 11 is inserted, the first spring telescopic rod 13 is pressed to contract, and the block 14 is retracted. As the roller 11 goes deeper, the block 14 is aligned with the slot 12. At this time, the first spring telescopic rod 13 bounces the block 14 into the slot 12 to lock the plug-in rod 10.

[0026] The second elastic fixing member includes a second spring telescopic rod 15 and a socket 16, one end of the second spring telescopic rod 15 is fixedly connected to the inner wall of the socket 9, and the other end of the second spring telescopic rod 15 is fixedly connected to the socket 16, and the socket 16 is adapted to the roller 11. When the roller 11 is inserted to the innermost side, the roller 11 presses the second spring telescopic rod 15 to drive the socket 16 to retract. At the same time, the elastic potential energy of the second spring telescopic rod 15 pushes the socket 16 to always fit with the roller 11, thereby limiting the roller 11.

[0027] The fixing assembly includes a fixing plate 17 and an adjusting assembly. The fixing plate 17 is symmetrically arranged at the bottom of the mounting base 5. The fixing plate 17 is L-shaped. An adjusting assembly for adjusting the movement of the two groups of fixing plates 17 is arranged inside the mounting base 5. By arranging the fixing plate 17 into an L-shape, the fixing plate 17 can support the device when the device is placed on the ground, thereby increasing the installation method of the device and further increasing the functionality of the device.

[0028] The adjusting assembly comprises a bidirectional screw 18, a nut sleeve 19, a connecting plate 20, a slide groove 21 and a rotating handle 22. The bidirectional screw 18 is rotatably installed inside the mounting seat 5, and the bidirectional screw 18 is symmetrically threadedly installed with a nut sleeve 19. A slide groove 21 is provided at the bottom of the mounting seat 5, and a connecting plate 20 is fixed to the bottom of the nut sleeve 19. The lower end of the connecting plate 20 passes through the slide groove 21 and is fixedly connected to the fixing plate 17. A rotating handle 22 for driving the threaded rod to rotate is provided on the outer wall of one end of the mounting seat 5. When the device is installed on the fixing column 4, the rotating handle 22 is rotated, and the rotating handle 22 drives the bidirectional screw 18 to rotate, thereby driving the connecting plate 20 to move through the movement of the nut sleeve 19, thereby driving the two groups of fixing plates 17 to move inward and clamped on the fixing column 4, thereby completing the installation of the device, which is relatively convenient during installation and disassembly.

[0029] Both sides of the cabinet 1 are provided with a plurality of heat dissipation holes 23 , and the plurality of heat dissipation holes 23 are distributed at equal intervals. The arrangement of the plurality of heat dissipation holes 23 ensures the heat dissipation of the device.

[0030] The inner wall of the fixing plate 17 is provided with anti-skid stripes at the position where the fixing column 4 is in contact. The provision of the anti-skid stripes further increases the firmness of the clamping of the fixing plate 17, thereby increasing the stability of the installation of the device.

[0031] The low-voltage distribution cabinet that is easy to disassemble and assemble has two usage modes. When used on the ground, the device can be directly supported by the support plate. When it needs to be installed on the fixed column 4 for use, the rotating handle 22 is rotated, and the rotating handle 22 drives the bidirectional screw 18 to rotate, thereby driving the connecting plate 20 to move through the movement of the nut sleeve 19, thereby driving the two groups of fixed plates 17 to move inward and clamped on the fixed column 4. When installing the electrical component 8, the electrical component 8 is first installed on the second mounting plate 7 outside, and then the plug-in rod 10 is inserted into the clamping seat 9, and the inserted plug-in rod 10 is limited and locked by the first elastic fixing member and the second elastic fixing member, thereby completing the installation of the electrical component 8.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
