[0003] For example, an explosion-proof electrical instrument body with the authorization announcement number "CN210928230U" is provided. When the outside of the explosion-proof electrical instrument body is hit or subjected to collision force, the two springs offset the external force through their own elastic action, thereby avoiding some shortcomings of the existing explosion-proof electrical instrument body during use. The explosion-proofness of the explosion-proof electrical instrument body only protects the internal structure from damage, but if the outside is hit or dropped during normal use, it will cause damage, and there is a problem of lack of protective structure. However, in the use of the explosion-proof electrical instrument body, although the explosion-proof electrical instrument body is protected against explosion by wrapping, the movement of the explosion-proof electrical instrument body requires continuous rotation of the screw rod to control the movement of the slider, and the position of the explosion-proof electrical instrument body is adjusted by the slider, which increases the operation and use and also increases the labor of the operator's hands, increases the difficulty of operating the explosion-proof electrical instrument body, and reduces the working efficiency of the explosion-proof electrical instrument body.

DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings:

[0021] Embodiment 1:

[0022] See also Figure 1 -:6: In the present embodiment, an explosion-proof electrical instrument body comprises a box body 1 and a slide groove 4. The bottom of the inner wall of the box body 1 is processed with the slide groove 4. The inner wall of the slide groove 4 is slidably connected with a slider 5. The slider 5 is subjected to force to slide back and forth through the inner wall of the slide groove 4. The top of the slider 5 is connected with a control structure 2. The top of the control structure 2 is connected with a round rod 6. The top of the round rod 6 is fixedly connected with an explosion-proof electrical instrument body 7.

The front of the bottom of the top plate 201 is fixedly connected to the top of the vertical rod 202. The outer wall of the vertical rod 202 is slidably connected with a vertical cylinder 203. The vertical cylinder 203 is subjected to force to slide up and down through the outer wall of the vertical rod 202. A circular ring 204 is fixedly connected to the top of the outer wall of the vertical cylinder 203. A spring 205 is sleeved on the outer wall of the vertical rod 202. The two ends of the spring 205 are respectively fixedly connected to the bottom of the top plate 201 and the top of the circular ring 204. After the vertical cylinder 203 is subjected to force to move the circular ring 204 upward, it rebounds by the elastic force of the spring 205. The bottom of the outer wall of the vertical cylinder 203 is plugged into the front of the bottom of the inner wall of the box body 1. The top of the top plate 201 is rotatably connected to the bottom of the outer wall of the round rod 6. The round rod 6 is subjected to force to rotate through the top bearing of the top plate 201.

[0024] Then, the vertical cylinder 203 is held and moved upward through the control structure 2. The moving vertical cylinder 203 moves upward on the outer wall of the vertical rod 202. At this time, the bottom of the outer wall of the vertical cylinder 203 is separated from the bottom of the inner wall of the box body 1. Then, the vertical cylinder 203 is pulled forward, and the vertical rod 202 is cooperated to move the top plate 201 forward. The moving top plate 201 causes the slider 5 to move forward on the inner wall of the slide groove 4. When the top plate 201 moves out of the box body 1, the explosion-proof electrical instrument main body 7 is already outside the box body 1. Then, the explosion-proof electrical instrument main body 7 is inspected and repaired, that is, the original screw screwing form is changed, which reduces the difficulty of operating the explosion-proof electrical instrument main body and improves work efficiency.

[0025] The left and right sides of the front of the box body 1 are fixedly connected with the first magnetic block 10 respectively, the first magnetic block 10 is the positive pole, the front of the first magnetic block 10 is adsorbed and connected with the second magnetic block 12, the second magnetic block 12 is the negative pole, the outer wall of the second magnetic block 12 is fixedly connected with the door panel 11, the outer side of the rear end face of the door panel 11 is in contact with the front of the box body 1, the inner wall of the door panel 11 is fixedly connected with the glass plate 14, the left and right sides of the front of the door panel 11 are fixedly connected with the handles 13 respectively, the handles 13 are convenient for pulling the door panel 11 forward, the limiting structure 3 includes a square plate 301 and a vertical rod 302, the inner sides of the two square plates 301 are respectively fixedly connected with the left and right bottom sides of the explosion-proof electrical instrument body 7, the inner wall of the square plate 301 is slidably engaged with the outer wall of the vertical rod 302, the vertical rod 302 is subjected to force to slide up and down through the inner wall of the square plate 301, the top of the vertical rod 302 is fixedly connected with a round block 303, and the bottom of the outer wall of the vertical rod 302 is plugged into the top of the top plate 201.

[0026] Working principle:

[0027] When the explosion-proof electrical instrument body 7 is in use, the box body 1 cooperates with the door panel 11 to shield and protect the explosion-proof electrical instrument body 7, thereby providing explosion-proof protection. The glass plate 14 on the front of the door panel 11 facilitates viewing of the readings of the explosion-proof electrical instrument body 7.

[0028] Main body inspection of explosion-proof electrical instruments:

[0029] The grip handle 13 is pulled forward, and the handle 13 moves the door panel 11 forward. The second magnetic block 12 on the outer wall of the door panel 11 is separated from the first magnetic block 10, so that the door panel 11 is separated from the front of the box body 1. At this time, the box body 1 is opened. Then, the vertical cylinder 203 is held and moved upward. The moving vertical cylinder 203 moves upward on the outer wall of the vertical rod 202. At this time, the bottom of the outer wall of the vertical cylinder 203 is separated from the bottom of the inner wall of the box body 1. Then, the vertical cylinder 203 is pulled forward, and the vertical rod 202 is cooperated to move the top plate 201 forward. The moving top plate 201 makes the slider 5 move forward on the inner wall of the slide groove 4. When the top plate 201 moves out of the box body 1, the explosion-proof electrical instrument main body 7 is already outside the box body 1, and then the explosion-proof electrical instrument main body 7 can be inspected and repaired.

[0030] Rear inspection of explosion-proof electrical instrument body:

[0031] The round block 303 moves upward with the vertical rod 302 through the square plate 301. At this time, the outer wall bottom of the vertical rod 302 is separated from the top of the top plate 201. Then the explosion-proof electrical instrument body 7 rotates 180 degrees on the top of the top plate 201 through the round rod 6. At this time, the rear of the explosion-proof electrical instrument body 7 is ahead, which is convenient for operators to perform maintenance. After the installation is completed, the above operation is reversed to move the explosion-proof electrical instrument body 7 into the interior of the box body 1, so that the first magnetic block 10 and the second magnetic block 12 are adsorbed, and the box body 1 and the door panel 11 are closed.

[0032] Embodiment 2:

[0033] See also Figure 1 -:6: In this embodiment, an explosion-proof electrical instrument body also includes a mesh plate 15 and a bent plate 16.

[0034] Working principle:

[0035] The mesh plate 15 is plugged into the inner wall of the square frame 9. At this time, the mesh plate 15 blocks the through hole 8. The mesh plate 15 is made of stainless steel and filled with a pp filter to ensure heat dissipation while preventing dust from entering. The bent plate 16 is a counterweight block that can make the mesh plate 15 more stable in the square frame 9.
