[0027] Please refer to Figures 1-8As shown in the figure, a dust-proof and insulating housing for a switch includes a switch body 1 and an insulating housing 2. A switch is provided on the top of the switch body 1 and heat dissipation holes are provided. Network cable interfaces are provided on the surface of the switch body 1. On the upper and lower sides of the inner wall of the insulating housing 2, a top plate 3 and a bottom plate 4 are respectively fixedly connected. Insulating blocks 5 are fixedly connected to both the upper and lower sides of the inner wall of the insulating housing 2. The top of the upper insulating block 5 is fixedly connected to the bottom of the top plate 3, and the bottom of the lower insulating block 5 is fixedly connected to the top of the bottom plate 4. A fixing frame 6 is embedded in the top of the top plate 3. A heat dissipation groove is provided on the top of the top plate 3, and a dust-proof net is embedded in the inner wall of the heat dissipation groove. Heat dissipation plates 7 are embedded on the surfaces of both sides of the insulating housing 2. A heat conduction plate 8 is fixedly connected to the surface of the heat dissipation plate 7. The heat conduction plate 8 guides the heat inside the insulating housing 2 to the heat dissipation plate 7, and then the heat dissipation plate 7 can dissipate the heat generated by the insulating housing 2 to the outside. A sealing mechanism 9 is installed on the top of the fixing frame 6. A vertical plate 10 is detachably connected inside the insulating housing 2. Card slots 11 are provided on both sides of the inner wall of the insulating housing 2. Card strips 12 are fixedly connected to both sides of the surface of the vertical plate 10. The surface of the card strip 12 is in contact with the inner wall of the card slot 11. A cross plate 13 is fixedly connected to the top of the vertical plate 10. The two sides of the bottom of the cross plate 13 are respectively in contact with the two sides of the top of the insulating housing 2. Limit plates 14 are fixedly connected to both sides of the surface of the cross plate 13. The inner surface of the limit plate 14 is in contact with the surface of the insulating housing 2. A limit mechanism 15 is installed on the surface of the insulating housing 2. A through groove is provided on the surface of the vertical plate 10 and an extension plate 16 is fixedly connected. A cover plate 17 is hinged to the surface of the extension plate 16. A sealing gasket is fixedly connected to the surface of the cover plate 17. The surface of the sealing gasket is in contact with the inner wall of the through groove. The sealing gasket is made of rubber, and the sealing gasket can seal the restricted through groove, thereby reducing the possibility of dust affecting the switch body 1. A pull plate 18 is fixedly connected to the bottom of the switch body 1. Short columns 19 are fixedly connected to both sides of the top of the bottom plate 4. A ball is embedded in the top of the short column 19. The surface of the ball is in contact with the bottom of the pull plate 18. The surface of the vertical plate 10 is in contact with the surface of the switch body 1. Through the cooperation of the short column 19, the ball and the pull plate 18, the switch body 1 can be further supported on the basis of the insulating block 5, and at the same time, it is convenient for the staff to move the switch body 1 out of the insulating housing 2 for maintenance of the switch body 1. An auxiliary mechanism 20 is installed on the surface of the bottom plate 4. The auxiliary mechanism 20 and the vertical plate 10 cooperate to better seal the gap between the switch body 1 and the bottom plate 4, so as to reduce the possibility of dust affecting the switch body 1.

[0028] The sealing mechanism 9 includes a column 91, a thin plate 92 and a pull rod 93. The column 91 is fixedly connected to the top of the fixed frame 6. The thin plate 92 is fixedly connected to the top of the column 91. A sealing block 94 is slidably sleeved on the surface of the column 91. An auxiliary groove is formed in the top of the fixed frame 6. The surface of the sealing block 94 is in contact with the inner wall of the auxiliary groove. The pull rod 93 slidably penetrates through the thin plate 92. The bottom of the pull rod 93 is fixedly connected to the top of the sealing block 94. A first compression spring 95 is sleeved on the surface of the column 91. The two ends of the first compression spring 95 are respectively fixedly connected to the bottom of the thin plate 92 and the top of the sealing block 94. When the staff pulls the pull rod 93, the sealing block 94 rises and moves out of the inside of the auxiliary groove, so that the staff can use the switch body 1. After that, under the action of the elastic force of the first compression spring 95, the sealing block 94 descends and seals the auxiliary groove, so as to reduce the possibility of dust entering the inside of the insulating housing 2 through the auxiliary groove.

[0029] The limiting mechanism 15 includes a rotating shaft 151, a limiting disc 152 and a rotating disc 153. The rotating shaft 151 rotatably penetrates through the insulating housing 2. The number of the limiting discs 152 and the rotating discs 153 is two. The two limiting discs 152 are respectively fixedly connected to the two ends of the rotating shaft 151, and the surface of the limiting disc 152 is in contact with the surface of the insulating housing 2. The rotating disc 153 is fixedly connected to the surface of the limiting disc 152. The surface of the limiting disc 152 is in contact with the surface of the limiting plate 14. When the staff rotates the rotating disc 153, the limiting disc 152 rotates accordingly. At this time, by the cooperation of the limiting disc 152 and the limiting plate 14, the height of the limiting plate 14 can be limited, and thus the state of the vertical plate 10 can be fixed.

[0030] The auxiliary mechanism 20 includes a hollow box 201, an auxiliary plate 202 and a second compression spring 203. The hollow box 201 is fixedly connected to the surface of the bottom plate 4. The auxiliary plate 202 slidably penetrates through the top of the hollow box 201. The second compression spring 203 is arranged inside the hollow box 201. The two ends of the second compression spring 203 are respectively fixedly connected to the bottom of the inner wall of the hollow box 201 and the bottom of the auxiliary plate 202. When the staff presses the auxiliary plate 202, the auxiliary plate 202 can be received inside the hollow box 201. At this time, the staff can move the switch body 1 out of the inside of the insulating housing 2. After that, under the action of the elastic force of the second compression spring 203, the auxiliary plate 202 rises and is in contact with the surface of the vertical plate 10, and thus the gap below can be sealed.

[0031] Working principle: When in use, the insulating housing 2 can protect the switch body 1 and reduce the harm to surrounding staff when electric leakage occurs on the surface of the switch body 1. After the staff places the switch body 1 inside the insulating housing 2, the short column 19 and the ball cooperate with the pulling plate 18 to support the switch body 1, and several insulating blocks 5 can fix the corners of the switch body 1. After that, when the staff places the vertical plate 10 inside the insulating housing 2, the position of the vertical plate 10 can be fixed through the cooperation of the card slot 11 and the card strip 12. Then, when the staff rotates the turntable 153, the limiting plate 14 can be fixed through the limiting disc 152 to stabilize the state of the vertical plate 10. Finally, when the staff rotates the cover plate 17, the data cable can be connected to the switch body 1 so that the switch body 1 can be used normally. Finally, when the staff pulls the pull rod 93, the sealing block 94 can be moved out of the auxiliary groove so that the staff can press the switch and start the switch body 1. When the switch body 1 is in use, the heat dissipation plate 7 and the heat conduction plate 8 cooperate to dissipate the heat inside the insulating housing 2 to the outside. The heat dissipation holes at the top of the switch body 1 can also dissipate heat through the heat dissipation grooves, and the dust-proof net can reduce the influence of dust on the switch body 1.
