[0003] However, due to differences in the use environment, in rainy and humid areas, water often enters the mechanism box, causing the mechanism parts to rust and fail to operate normally. In windy and sandy areas, sand and dust often enter the mechanism box, causing jamming and making the mechanism unable to operate normally. Utility Model Content

[0004] The utility model aims to solve the problem of water and dust ingress into a combined electrical box in the background technology and proposes an isolation grounding mechanism box.

[0005] The technical solution of the utility model is: an isolation grounding mechanism box, comprising a bottom plate and a bent plate arranged on the bottom plate; and further comprising:

[0006] A cover plate, the cover plate is located above the bent plate, and the cover plate is detachably connected to the bent plate;

[0007] A sealing strip is arranged above the bent plate and surrounds the top of the bent plate;

[0008] And a sponge strip is arranged on the inner wall of the cover plate. When the cover plate is in a closed state, the sponge strip is in extrusion contact with the sealing rubber strip.

[0009] Preferably, a plurality of lock buckles are arranged on the outer side surface of the bent plate, and a plurality of buckles cooperating with the lock buckles are arranged on the cover plate.

[0010] Preferably, a perspective window is provided on the bent plate, through which the opening and closing states of the internal mechanism of the bent plate can be observed.

[0011] Preferably, an isolation grounding manual operation hole cover is provided on the bent plate, and the internal mechanism is manually opened and closed using tooling outside the box through the isolation grounding manual operation hole cover.

[0012] Preferably, a breathable cover is provided on the cover plate, and the breathable cover is used to discharge water vapor inside the box body and prevent external rainwater from entering.

[0013] Compared with the prior art, the utility model has the following beneficial technical effects: providing an isolated grounding mechanism box with high structural reliability, simple design, simple parts processing technology, easy assembly and low cost; reliable protection, and can effectively prevent rain and dust.

[0020] like Figure 1-Figure 5 As shown, the utility model proposes an isolation grounding mechanism box, including a bottom plate 1 and a bent plate 2 arranged on the bottom plate 1, the bottom plate 1 and the bent plate 2 are welded to form an integral structure, a plurality of pads 5 are arranged at the bottom of the bottom plate 1, the whole box is supported to make it off the ground, and the influence of moisture is reduced, a perspective window 4 is arranged on the bent plate 2, and the opening and closing state of the internal mechanism of the bent plate 2 is observed through the perspective window 4, and an isolation grounding manual operation hole cover plate 6 is arranged on the bent plate 2, and the internal mechanism is manually opened and closed by using a tool outside the box through the isolation grounding manual operation hole cover plate 6; the isolation grounding manual operation hole cover plate 6 is connected to the bent plate 2 by bolts; and also includes:

[0021] The cover plate 3 is located above the curved plate 2, and the cover plate 3 is detachably connected to the curved plate 2. A breathable cover 9 is provided on the cover plate 3, and the breathable cover 9 is used to discharge the water vapor inside the box body and prevent the entry of external rainwater. A plurality of lock buckles 7 are provided on the outer surface of the curved plate 2, and a plurality of buckles cooperating with the lock buckles 7 are provided on the cover plate 3. In an optional embodiment, four lock buckles 7 are provided, and the four lock buckles 7 are grouped in twos, and the two groups are respectively provided on opposite sides of the curved plate 2;

[0022] A sealing strip 8 is arranged above the bent plate 2 and surrounds the top of the bent plate 2;

[0023] And the sponge strip 10 is arranged on the inner wall of the cover plate 3. When the cover plate 3 is in a closed state, the sponge strip 10 is squeezed and contacted with the sealing strip 8, and two seals are formed by the sponge strip 10 and the sealing strip 8 to improve the sealing effect.

[0024] In the utility model, the box body has two sealing structures, namely, a sealing strip 8 is installed on the box body bent plate 2, and a sponge strip 10 is pasted inside the box body cover plate 3; the opening and closing state of the internal mechanism of the box body can be clearly observed through the perspective window 4; a wire outlet hole is arranged on the box body bent plate 2, and an aviation plug or a cable gland can be installed by changing the shape and size of the wire outlet hole; the breathable cover 9 can not only remove the water vapor inside the box body, but also prevent the entry of external rainwater; after removing the isolation grounding manual operation hole cover plate 6, the mechanism can be manually opened and closed using tooling outside the box; the box body cover plate 3 is tightly installed together with the box body bent plate 2 by four lock buckles 7; the box body bottom plate 1 welding pad 5 is used for the installation of the box body, and there is no through hole between the installation hole and the bottom plate 1, which can effectively prevent water and dust.

[0025] The utility model can provide an isolation grounding mechanism box body with high structural reliability, simple design, simple parts processing technology, easy assembly and low cost; the protection is reliable and can effectively prevent rain and dust.
