[0035] The technical solution of the present utility model will be further described below in conjunction with the accompanying drawings and through specific embodiments.

[0036] Electrical equipment is widely used in industry, commerce, and civil applications. When electrical equipment operates for a long time, a large amount of heat will be generated. To prevent dust from adhering to the electrical equipment and affecting heat dissipation, this embodiment provides a dust-proof box. The electrical equipment is arranged inside the dust-proof box to play a role in dust prevention.

[0037] As Figures 1 to 3 shown, in this embodiment, the dust-proof box includes a box body 1 and a dust suction assembly 2. The box body 1 is configured to place the electrical equipment. The dust suction assembly 2 includes a dust suction member 21 and a dust suction head 22. The dust suction member 21 is in communication with the dust suction head 22. The dust suction member 21 can adsorb the dust inside the box body 1 through the dust suction head 22, ensuring that the dust amount inside the box body 1 is at a relatively low level, thereby avoiding dust covering the electrical equipment and affecting the heat dissipation of the electrical equipment.

[0038] However, as the usage time prolongs, the dust suction head 22 will gradually be blocked by dust, resulting in a decline in the dust suction effect, an increase in energy consumption, and also affecting the service life of the electrical equipment.

[0039] As Figure 4As shown in the figure, to solve the above problems, in the dust-proof box provided in this embodiment, the box body 1 is provided with an installation groove 11. A clamping block 12 is telescopically arranged on the side wall of the installation groove 11. The installation groove 11 is provided with a dust suction hole connecting the inside and outside of the box body 1. The dust suction head 22 is arranged in the installation groove 11 and is clamped and fixed with the clamping block 12. The dust suction member 21 is configured to suck dust from the dust suction hole through the dust suction head 22.

[0040] In this dust-proof box, the dust suction member 21 of the dust suction assembly 2 can suck dust from the dust suction hole through the dust suction head 22, so as to ensure that the electrical equipment inside the box body 1 will not be covered with dust. When the dust suction head 22 is blocked, resulting in a poor dust suction effect or increased energy consumption, the operator can unlock the dust suction head 22 by sliding the clamping block 12, so as to replace or clean the dust suction head 22, and then re-install the new dust suction head 22 or the cleaned dust suction head 22 into the installation groove 11 and clamp and fix it with the clamping block 12.

[0041] This dust-proof box can disassemble the dust suction head 22, which is convenient for the maintenance and cleaning of the dust suction head 22, so as to ensure the dust suction effect of the dust suction assembly 2 and avoid increased energy consumption.

[0042] In this embodiment, the dust suction assembly 2 further includes a dust storage box 23. The dust storage box 23 is arranged beside the box body 1. The dust suction member 21 is communicated with the dust storage box 23. Dust enters the dust storage box 23 after passing through the dust suction head 22 and the dust suction member 21 in sequence, so as to prevent dust from floating around and affecting the environment. Specifically, the dust suction member 21 is a fan.

[0043] As Figure 3 shown, the dust suction assembly 2 further includes a dust suction pipe 24 and a dust discharge pipe 25. The dust suction pipe 24 connects the dust suction head 22 and the dust suction member 21, and the dust discharge pipe 25 connects the dust storage box 23 and the dust suction member 21, so that dust can enter the dust storage box 23 from the dust suction head 22 and prevent dust from escaping.

[0044] In this embodiment, the dust suction assembly 2 further includes a support plate 26. The support plate 26 is fixedly arranged on the box body 1 and is connected to the dust storage box 23. The dust suction member 21 is fixedly arranged on the support plate 26. The support plate 26 can improve the stability of the dust suction member 21, reduce the vibration amplitude of the dust suction member 21 during operation, and also reduce noise.

[0045] As Figure 2 and Figure 5 shown, the dust suction head 22 is connected with a pressing block 221. The pressing block 221 is provided with a sliding surface. The pressing block 221 can drive the clamping block 12 to retract through the sliding surface. When the operator installs the dust suction head 22 into the installation groove 11, the sliding surface of the pressing block 221 abuts against the clamping block 12 and can apply a force to push the clamping block 12 to retract, so that the dust suction head 22 can be installed into the installation groove 11, and then the clamping block 12 extends out to be clamped and fixed with the pressing block 221.

[0046] In some embodiments, the clamping block 12 is provided with a sliding surface. When an operator installs the dust suction head 22 into the installation groove 11, the pressing block 221 abuts against the sliding surface of the clamping block 12, and applies a force to the clamping block 12 through the sliding surface to push the clamping block 12 to retract, so that the dust suction head 22 can be installed into the installation groove 11, and then the clamping block 12 extends out to be clamped and fixed with the pressing block 221.

[0047] In this embodiment, both the pressing block 221 and the clamping block 12 are provided with sliding surfaces. For the convenience of description, the sliding surface of the pressing block 221 is called the first sliding surface 2211, and the sliding surface of the clamping block 12 is called the second sliding surface 121. The first sliding surface 2211 and the second sliding surface 121 are parallel to each other. When an operator installs the dust suction head 22 into the installation groove 11, the first sliding surface 2211 and the second sliding surface 121 are in sliding fit. Since it is a surface contact, the wear of the first sliding surface 2211 and the second sliding surface 121 can be reduced, and the frictional resistance can also be reduced, making it easier for the dust suction head 22 to be inserted into the installation groove 11.

[0048] As Figure 5 shown, a chute 13 is formed in the side wall of the installation groove 11, and an elastic member 14 is arranged in the chute 13. The elastic member 14 abuts against the clamping block 12 and elastically drives the clamping block 12 to extend out of the chute 13. During the process of the operator installing the dust suction head 22 into the installation groove 11, the clamping block 12 is driven by the pressing block 221 to retract. When the dust suction head 22 is completely installed into the installation groove 11, the elastic member 14 can drive the clamping block 12 to pop out and be clamped and fixed with the pressing block 221.

[0049] In this embodiment, the clamping block 12 is connected with a pull rod 15. A connecting groove penetrating through the surface of the box body 1 is formed in the chute 13, and the pull rod 15 is arranged in the connecting groove and extends out of the surface of the box body 1. The operator can slide the clamping block 12 through the pull rod 15 to disengage the clamping block 12 from the pressing block 221, so as to facilitate the operator to disassemble the dust suction head 22 for replacement or cleaning.

[0050] Generally, the clamping block 12 abuts against the upper surface of the pressing block 221, which can only ensure that the dust suction head 22 will not fall out of the installation groove 11, but cannot ensure the stability of the dust suction head 22. To solve the above problems, a clamping groove 2212 is formed at one end of the pressing block 221 facing the clamping block 12. The clamping block 12 is in clamping fit with the clamping groove 2212 to fix the dust suction head 22 in the installation groove 11. Among them, the clamping fit between the pressing block 221 and the clamping groove 2212 can ensure the stability of the position of the dust suction head 22 and ensure the stability of the dust suction head 22 in the height direction.

[0051] In this embodiment, the clamping block 12 includes a clamping section 123 and a guide section 122, the second sliding surface 121 is arranged on the guide section 122, and the guide section 122 and part of the clamping section 123 are both inserted into the clamping groove 2212 so that the clamping block 12 is clamped with the clamping groove 2212. The upper and lower surfaces of the clamping section 123 are both planes, so it can be clamped with the clamping groove 2212 in the vertical direction, which can prevent the dust collector 22 from moving upward or downward.

[0052] It is understandable that the electrical equipment is prone to vibration during operation, and the vacuum head 22 will generate negative pressure when sucking dust inside the box 1, thereby causing the electrical equipment to shift. Figure 2 and Figure 3 As shown, in order to ensure the stability of the electrical equipment, the dustproof box also includes a clamping assembly 3, which includes a driving member 32 and two clamping members 31. The two clamping members 31 are movably arranged inside the box body 1 and are arranged at intervals. The driving member 32 is transmission-connected to the two clamping members 31 to drive the two clamping members 31 to move closer to or away from each other.

[0053] When the electrical equipment needs to be operated, the driving member 32 can drive the two clamping members 31 to clamp the electrical equipment, thereby improving the stability of the electrical equipment; when the electrical equipment needs to be repaired, the driving member 32 can drive the two clamping members 31 to move away from each other and release the electrical equipment for easy repair.

[0054] To simplify the structure, the clamping assembly 3 also includes a double-ended screw 33, which includes a first thread segment 331 and a second thread segment 332 with opposite thread directions. One clamping member 31 is threadedly connected to the first thread segment 331, and the other clamping member 31 is threadedly connected to the second thread segment 332. The driving member 32 is transmission-connected to the double-ended screw 33 to drive the double-ended screw 33 to rotate.

[0055] When the double-headed screw 33 rotates, the two clamping members 31 will move in opposite directions driven by the first thread segment 331 and the second thread segment 332 respectively to fix or release the electrical equipment. In addition, this structure can be driven by only one driving member 32, saving costs, and the two clamping members 31 can achieve synchronous movement to ensure the accurate position of the electrical equipment.

[0056] like Figure 2 and Figure 4 As shown, the clamping assembly 3 also includes a guide rod 34, which is inserted into the two clamping members 31. The setting of the guide rod 34 can provide a guide for the movement of the clamping member 31, ensuring that the clamping member 31 will not deviate and get stuck with the double-headed screw 33, and can also make the two clamping members 31 move on the same straight line, ensuring that the directions of the forces of the two clamping members 31 when clamping the electrical equipment are on the same straight line and in opposite directions, which can improve the stability of the clamping member 31 when clamping the electrical equipment.

[0057] Generally, electrical equipment needs to be placed on the bottom surface of the box body 1. In order to avoid the double-headed lead screw 33 occupying space and affecting the placement of the electrical equipment, a receiving groove 16 is provided on the bottom surface of the box body 1, and two clamping members 31 are slidably arranged on the bottom surface, and the double-headed lead screw 33 is rotatably arranged in the receiving groove 16.

[0058] In this embodiment, a plurality of receiving grooves 16 are provided on the bottom surface of the box body 1, and the guide rods 34 are also arranged in the receiving grooves 16 to avoid the guide rods 34 occupying space. Specifically, there are two guide rods 34, and the two guide rods 34 are arranged at intervals and in parallel. Each clamping member 31 is adapted to the two guide rods 34 to further improve the accuracy of the movement of the clamping member 31.

[0059] As Figures 1 to 4 shown, in order to improve the dust-proof ability on the premise of ensuring effective heat dissipation, the box body 1 is provided with ventilation windows, and a dust-proof plate 18 and a dust-proof screen 17 are arranged at the ventilation windows. Among them, the dust-proof screen 17 is located inside the dust-proof plate 18. Among them, the dust-proof plate 18 has protection holes, so the dust-proof plate 18 can block larger dust or particles, thereby protecting the dust-proof screen 17, and the dust-proof screen 17 can block smaller dust or particles to reduce the total amount of dust inside the box body 1.

[0060] In this embodiment, the box body 1 is provided with a door body 19, and the door body 19 is pivotally connected to the box body 1. The door body 19 can open or close the box body 1, which can not only ensure a good internal environment of the box body 1, but also facilitate the operator to repair the internal structure of the box body 1.

[0061] The above content is only the preferred embodiment of the present invention. For those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. The content of this specification should not be construed as a limitation to the present invention.
