The main function of explosion -proof distribution box is to prevent internal electric spark from igniting the external explosive mixture, and to ensure that there is no danger to the external environment when internal failure occurs.
[0003] At present, the box body and the box cover on most explosion -proof distribution boxes have wiring, and the wires are connected between the box body and the box cover. When the inside of the explosion -proof distribution box is overhauled, the box cover is separated from the box body, but the wires on the box cover and the box body are still connected, at this time, a person must hold the box cover to prevent the box cover from falling down and pulling off the wires, which is time -consuming and labor -intensive, and long -term work may cause the box cover to fall off and cause the wires to be disconnected due to mistakes. Or all the wires are disconnected and the box cover is completely removed for maintenance operation. This maintenance is very troublesome, and a lot of time and labor are needed, and the work efficiency is low.
[0004] Therefore, it is necessary to provide a maintenance auxiliary tool for explosion -proof distribution box to solve the above technical problems. CONTENT OF UTILITY MODEL

Then the supporting rod 10 is inserted through the hole 9 on the box cover 2, and then the threaded end of the supporting rod 10 is aligned with the threaded hole 8 and is screwed in, so as to fix the supporting rod 10 with the second clamping jaw 7, and at this time the box cover 2 is hung on the supporting rod 10, that is, the box cover 2 is supported by the supporting rod 10, and then the worker can perform the maintenance operation in the box body 1, avoiding the current way of supporting the box cover 2 by another worker, saving the labor of another worker, and preventing the worker from making mistakes to cause the box cover 2 to fall off and cause the wires to be disconnected or separated, better protecting the box cover 2 and the wires connected thereto; At the same time, it is not necessary to remove the wires on the box cover 2 to completely remove the box cover 2 in a cumbersome way, and the operation is more simple and convenient, a large amount of labor and time is saved, the working efficiency of the maintenance is significantly improved, the working process is effectively accelerated, and the practicability is high, so it can be widely used.
[0039] In the embodiment, preferably, please refer to Figure 1 and Figure 3 The sleeve plate 3 is also provided with a supporting block 11, and the limiting mechanism 5 is installed on the supporting block 11 and used to limit the movement of the sleeve plate 3. When the first clamping jaw 6 and the second clamping jaw 7 are clamped on the two sides of the box body 1 respectively, and at this time the movement of the inner moving plate 4 is restricted by the limiting mechanism 5 on the sleeve plate 3, at this time the movement of the sleeve plate 3 is restricted by the limiting mechanism 5, that is, the sleeve plate 3 is prevented from being offset on the box body 1, so as to improve the stability of the first clamping jaw 6 and the second clamping jaw 7, that is, the stability of the supporting rod 10 and the box cover 2 is improved, and the practicability is high.
[0040] In the embodiment, preferably, please refer to Figure 1 and Figures 3-4The limiting mechanism 5 comprises a fixing seat 51, a screw rod 52 is threadedly connected to the fixing seat 51, and a limiting block 53 is arranged at the end of the screw rod 52. The upper wall of the cover plate 3 and the supporting block 11 are both provided with a through hole 12 through which the limiting block 53 passes. By rotating the screw rod 52, the limiting block 53 is lifted. When the limiting block 53 is lifted to be separated from the inner shifting plate 4, the movement of the inner shifting plate 4 is released, and the inner shifting plate 4 can move along the cover plate 3. When the limiting block 53 is lowered to pass through the through hole 12 of the cover plate 3 and tightly press the upper wall of the inner shifting plate 4, the inner shifting plate 4 is limited. Similarly, when the limiting block 53 on the supporting block 11 is lowered to pass through the through hole 12 of the supporting block 11 and tightly press the upper wall of the box body 1, the deviation of the cover plate 3 can be limited.
[0041] In this embodiment, preferably, please refer to Figures 1-2 and Figures 5-7 Further comprising a baffle 13, which is detachably arranged on the supporting rod 10. The baffle 13 is provided with a through hole 14, and a clamping arc plate 15 is arranged in the through hole 14. The baffle 13 is provided with a transmission component 16 for moving the clamping arc plate 15.
[0042] Before the supporting rod 10 is inserted into the insertion hole 9 of the box cover 2, the transmission component 16 is operated to move the clamping arc plate 15. Then the supporting rod 10 is inserted into the through hole 14 of one baffle 13. After that, the supporting rod 10 is inserted into the insertion hole 9 of the box cover 2. Then the supporting rod 10 is inserted into the through hole 14 of another baffle 13. At this time, there are two baffles 13 on the supporting rod 10, and the box cover 2 is located between the two baffles 13. After the end of the supporting rod 10 is screwed into the threaded hole 8 of the second clamping jaw 7, the clamping arc plate 15 is moved to be separated from the outer wall of the supporting rod 10 by the transmission component 16. At this time, the baffle 13 can be moved back and forth along the supporting rod 10. Then the box cover 2 is moved along the supporting rod 10, so that the box cover 2 is moved to the appropriate position away from the box body 1. Then the two baffles 13 are located on the two sides of the box cover 2 and are attached to the box cover 2. After that, the transmission component 16 is not operated any more. The supporting rod 10 is clamped by the clamping arc plate 15. At this time, the baffle 13 is relatively fixed with the supporting rod 10. At this time, the box cover 2 in the middle can be limited by the two baffles 13, so that the movement of the box cover 2 on the supporting rod 10 is avoided. Not only the wiring on the box cover 2 can be protected, but also the situation that the wiring is pulled off or separated due to the random movement of the box cover 2 during the maintenance is avoided. Moreover, the stability of the box cover 2 is greatly improved, so that the staff can better and more conveniently maintain the box body 1, and the practicability is high.

When the baffle 13 moves to a specified position, the pressing block 163 is released, the connecting rod 161 is no longer pulled, and the elastic force of the first elastic member 162 drives the connecting rod 161 to move, so that the connecting rod 161 drives the clamping arc plate 15 to return to the initial position, i.e. the two clamping arc plates 15 move close to each other, and finally clamp the supporting rod 10.
[0045] The second elastic member 23 is arranged between the pressing block 163 and the inner wall of the lower moving cavity 17, the first elastic member 162 in the application is a spring or other means with a damper, the second elastic member 23 is pressed when the pressing block 163 is pressed, and the second elastic member 23 drives the pressing block 163 to move back to the initial state when the pressing block 163 is released, so that the stability of the movement of the pressing block 163 is improved, and the stress of the first elastic member 162 is shared, and the use effect is improved.
[0046] In the embodiment, preferably, please refer to Figures 6-7The passage 19 is communicated with the upward moving cavity 18, and the sliding groove 20 is communicated with the passage 19 in the downward moving cavity 17.

One end of the sliding block 1641 is provided with a traction rope 1642, and the other end of the traction rope 1642 is connected with the connecting rod 161 through the passage 19 and the upward moving cavity 18. When the pressing block 163 is pressed to move, the pressing block 163 drives the sliding block 1641 to move along the sliding groove 20, the sliding block 1641 pulls the traction rope 1642, and the other end of the traction rope 1642 pulls the connecting rod 161, so that the connecting rod 161 moves towards the upward moving cavity 18. When the pressing block 163 is released, the first elastic member 162 drives the connecting rod 161 to move back to the initial position, and the connecting rod 161 pulls the traction rope 1642, so that the traction rope 1642 drives the sliding block 1641 and the pressing block 163 to move to the initial position.
