AI Technical Summary
The existing low-voltage distribution box requires frequent loosening and tightening of nuts during maintenance, which is cumbersome, increases working time, and poses a risk of damage due to instability during maintenance.
By introducing support legs and counterweight components into the distribution box, the support legs automatically drop down and provide support when the component cabinet is pulled out, and the counterweight components remain stable when the component cabinet moves. The smooth movement of the component cabinet is achieved by using a gear meshing mechanism.
It simplifies maintenance operations, reduces working time, and maintains the stability of the distribution box through counterweight components, preventing damage caused by center of gravity deviation.

Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative efforts fall within the scope of the present application. Figure 4 The moving assembly 2 comprises an element cabinet 201, a plurality of first sliding rods 202 are fixedly installed on both sides of the element cabinet 201, a handle 203 is fixedly installed on one side of the surface of the element cabinet 201, second sliding rods 204 are fixedly installed on both sides of the bottom end of the element cabinet 201, limit blocks 205 are fixedly installed on one side of the bottom end of the second sliding rods 204, a first toothed plate 206 is fixedly installed at the middle of the bottom end of the element cabinet 201, a sliding groove 207 is formed in the inner side of the bottom end of the element cabinet 201, and placing grooves 208 are formed on both sides of the bottom end of the element cabinet 201.
[0029] Specific, with the handle 203 of the element cabinet 201 surface bottom end element cabinet 201 pull out, in the pull out at the same time, the first sliding rod 202 will move along the first sliding rail 3 to the pulling direction, the second sliding rod 204 also moves along the second sliding rail 4 to the pulling direction, until the limit block 205 of the second sliding rod 204 bottom end moves to the one end of the groove 8, at this time, the element cabinet 201 can't move again, in the element cabinet 201 moves the support leg 209 will fall down, with the element cabinet 201 moves outward, the bottom end of the support leg 209 will be right when contact with the ground, make the support leg 209 support the element cabinet 201.
[0030] Referring to Figure 5 , the counterweight assembly 7 comprises a counterweight block 701, the counterweight block 701 is fixedly connected with connecting plates 702 on both sides, the second toothed plate 703 is fixedly installed on the upper surface of the connecting plate 702, the roller sliding rails 704 are fixedly arranged on both sides of the connecting plate 702, a plurality of rollers 705 are rotatably connected to the inner wall of the roller sliding rail 704, the roller sliding rail 704 is slidingly installed on the inner wall of the sliding groove 207, the roller 705 rolls on the inner wall of the sliding groove 207, the second toothed plate 703 is engaged with the gear 6;
[0031] Specific, because the first toothed plate 206 and the gear 6 are engaged, the second toothed plate 703 is also engaged with the gear 6, when the first toothed plate 206 drives the gear 6 to rotate, the counterweight assembly 7 will also move, at this time, the rollers 705 on both sides of the connecting plate 702 will roll in the sliding groove 207.
[0032] Working principle: when the distribution box needs to be overhauled, first open the box body 1, then use the handle 203 of the element cabinet 201 surface bottom end element cabinet 201 pull out, in the pull out at the same time, the first sliding rod 202 will move along the first sliding rail 3 to the pulling direction, the second sliding rod 204 also moves along the second sliding rail 4 to the pulling direction, until the limit block 205 of the second sliding rod 204 bottom end moves to the one end of the groove 8, at this time, the element cabinet 201 can't move again, in the element cabinet 201 moves the support leg 209 will fall down, with the element cabinet 201 moves outward, the bottom end of the support leg 209 will be right when contact with the ground, make the support leg 209 support the element cabinet 201, through the cooperation of the handle 203 and the second sliding rod 204, when the limit block 205 moves to the one end of the groove 8, because of the block, the element cabinet 201 can't be pulled out again, prevent the element cabinet 201 from being pulled out as a whole, cause damage, through the cooperation of the support leg 209 and the element cabinet 201, in the element cabinet 201 pull out at the same time, the support leg 209 loses the support of the bottom end of the box body 1 inside, will fall down, until straight, support the element cabinet 201, pull out the element cabinet 201, make the overhaul personnel check the distribution box, the operation is also convenient and fast;
[0033] Secondly, while pulling the handle 203, the first toothed plate 206 at the bottom end of the component cabinet 201 moves, which drives the gear 6 at the bottom end inside the box 1 to rotate. Since the first toothed plate 206 and the gear 6 are engaged, the second toothed plate 703 is also engaged with the gear 6. While the first toothed plate 206 drives the gear 6 to rotate, the counterweight assembly 7 also moves. At this time, the rollers 705 on both sides of the connecting plate 702 roll in the sliding groove 207 as they move. As the component cabinet 201 is pulled out, the counterweight assembly 7 moves inward, preventing the switchgear from being damaged due to unstable center of gravity when the component cabinet 201 is pulled out. Through the cooperation between the second toothed plate 703, the gear 6 and the first toothed plate 206, the counterweight assembly 7 is moved in the opposite direction of the movement of the component cabinet 201, ensuring that the switchgear will not be damaged due to deviation of the center of gravity.
[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent replacements to some technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
