[0002] A distribution box refers to a device used to distribute electricity and control electrical equipment, usually including components such as circuit protectors, circuit breakers, contactors, fuses, etc., to ensure the safe operation of the power system and the normal use of the equipment. The distribution box needs to be cleaned regularly to avoid safety hazards such as overheating, short circuit or fire caused by dust accumulation in the distribution box. In summary, the problems existing in the prior art are: a distribution box cleaning machine is a device specially used to clean dust and debris in a distribution box, usually consisting of a vacuum cleaner, a hose, a nozzle and a dust bag. The dust bag is installed on the cleaning machine body by threaded connection or snap connection. The threads and snaps are prone to wear or breakage after long-term use, resulting in unstable installation of the dust bag. If the dust bag is not installed stably, dust leakage is likely to occur, reducing the cleaning quality of the cleaning machine body. However, the cleaning machine used in the existing distribution cabinet does not have a component to fix the dust bag more stably, so a distribution box cleaning device is proposed to solve the above problems.

DETAILED DESCRIPTION

[0018] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0019] The structure of the utility model is described in detail below in conjunction with the accompanying drawings.

[0020] like Figures 1 to 4 As shown, an embodiment of the utility model provides a dust cleaning device for a distribution box, comprising a dust cleaning body 1 and a docking shell 2, the bottom of the dust cleaning body 1 is fixedly connected to the top of the docking shell 2, the surface of the docking shell 2 is movably connected to a mounting shell 3, the bottom of the mounting shell 3 is provided with a dust collecting bag 4, and the surface of the docking shell 2 is movably connected to four positioning devices 5.

[0021] refer to Figure 2 The positioning device 5 includes a positioning block 501, a top of the positioning block 501 is fixedly connected to a squeezing rod 502, a side of the positioning block 501 close to the docking shell 2 is fixedly connected to a spring 503, and a side of the spring 503 close to the docking shell 2 is fixedly connected to the surface of the docking shell 2.

[0022] With the above solution, by providing the positioning device 5 , when the dust bag 4 is installed on the dust cleaning body 1 , the positioning device 5 has a limiting effect on the position of the dust bag 4 .

[0023] refer to Figure 2 The side of the positioning block 501 close to the docking shell 2 is fixedly connected to the outer shell 6 , the inner cavity of the outer shell 6 is movably connected to the inner shell 7 , and the side of the inner shell 7 close to the docking shell 2 is fixedly connected to the surface of the docking shell 2 .

[0024] The above solution is adopted: by setting the outer shell 6 and the inner shell 7, when the positioning block 501 moves, the outer shell 6 will be driven to move along the surface of the inner shell 7. The coordinated use of the inner shell 7 and the outer shell 6 has a limiting effect on the moving position of the positioning block 501.

[0025] refer to Figure 2 The surface of the docking shell 2 is sleeved with an extrusion swivel 8 used in conjunction with the extrusion rod 502 , and the surface of the extrusion swivel 8 contacts the surface of the extrusion rod 502 .

[0026] The above solution is adopted: by providing the squeezing rotating ring 8, when the squeezing rotating ring 8 rotates, a squeezing force will be generated on the squeezing rod 502.

[0027] refer to Figure 4 Four movable sliders 9 are fixedly connected to the inner cavity of the extrusion swivel 8, and a movable slide groove 10 used in conjunction with the movable slider 9 is provided on the surface of the docking shell 2, and the surface of the movable slider 9 is movably connected to the inner cavity of the movable slide groove 10.

[0028] The above scheme is adopted: by setting the movable slider 9 and the movable slot 10, when the extrusion swivel 8 rotates, the movable slider 9 will be driven to rotate along the inner cavity of the movable slot 10. The coordinated use of the movable slider 9 and the movable slot 10 has a limiting effect on the rotation position of the extrusion swivel 8.

[0029] refer to Figure 3 The surface of the mounting shell 3 is provided with a positioning groove 11 used in conjunction with the positioning block 501 . There are four positioning grooves 11 which are evenly distributed on the surface of the mounting shell 3 . The surface of the positioning block 501 contacts the inner cavity of the positioning groove 11 .

[0030] The above scheme is adopted: by setting the positioning groove 11, when the mounting shell 3 moves to the inner cavity of the docking shell 2, the extrusion swivel 8 is released, and the restoring force generated by the spring 503 restoring its shape will drive the positioning block 501 to be stuck into the inner cavity of the positioning groove 11. The coordinated use of the positioning block 501 and the positioning groove 11 has a limiting effect on the position of the mounting shell 3.

[0031] refer to Figure 3 The inner cavity of the docking shell 2 and the surface of the mounting shell 3 are both provided with sealing gaskets 12, and the material of the sealing gaskets 12 is rubber.

[0032] The above solution is adopted: by providing the sealing gasket 12, the provision of the sealing gasket 12 increases the sealing performance of the connection between the docking shell 2 and the mounting shell 3, and effectively prevents the dust from leaking out when the dust collecting bag 4 collects dust.

[0033] When in use, when the dust collector used in the power distribution cabinet needs to fix the dust bag 4 more stably, the user first rotates the squeezing swivel 8. When the squeezing swivel 8 rotates, it will drive the moving slider 9 to rotate along the inner cavity of the moving slide groove 10. When the squeezing swivel 8 rotates, it will generate squeezing force on the squeezing rod 502. The squeezing rod 502 subjected to the squeezing force will drive the positioning block 501 to move to the side away from the docking shell 2. When the positioning block 501 moves, it will drive the outer shell 6 to move along the surface of the inner shell 7. When the positioning block 501 moves, the force generated causes the elastic The spring 503 undergoes elastic deformation. When the positioning block 501 moves to a position away from the docking shell 2, the mounting shell 3 is moved into the inner cavity of the docking shell 2. When the sealing gasket 12 on the surface of the mounting shell 3 is in close contact with the sealing gasket 12 in the inner cavity of the docking shell 2, the squeezing swivel 8 is released. The restoring force generated by the spring 503 restoring its shape will drive the positioning block 501 to be stuck into the inner cavity of the positioning groove 11. The coordinated use of the positioning block 501 and the positioning groove 11 has a limiting effect on the position of the dust bag 4. At this time, the dust cleaner used in the distribution cabinet can fix the dust bag 4 more stably.

[0034] To sum up: the cleaning device of the distribution box, by setting the positioning device 5, the positioning block 501, the extrusion rod 502, the spring 503 and the positioning groove 11 for coordinated use, solves the problem that the existing distribution box cleaning machine is a device specially used to clean dust and debris in the distribution box, usually composed of a vacuum cleaner, a hose, a suction nozzle and a dust bag, and the dust bag is installed on the cleaning machine body by threaded connection or snap connection. The threads and the snaps are prone to wear or breakage after long-term use, resulting in the phenomenon of unstable installation of the dust bag. If the dust bag is not installed stably, dust is likely to leak out, reducing the cleaning quality of the cleaning machine body. However, the cleaning machine used in the existing distribution cabinet does not have a component to fix the dust bag more stably.
