[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0026] Example 1, such as Figures 1-7 As shown, a switch cabinet rear door positioning device includes a switch cabinet 1, a rear door 11 rotatably connected to the inner wall of the back of the switch cabinet 1, two partitions 12 fixedly connected to the inner wall of the switch cabinet 1, a positioning component 2 inside the rear door 11, and a retraction component 3 on the outer surface of the rear door 11.
[0027] Specifically, in order to position the opened rear cabinet door, please refer to... Figure 4 and Figure 5 In this embodiment, the positioning component 2 includes a fixing block 21. The left end of the fixing block 21 is fixedly connected to the inner wall of the switch cabinet 1. The fixing block 21 is located between two partitions 12. A rotating rod 211 is rotatably connected to the outer surface of the fixing block 21. A connecting block 22 is rotatably connected to the right outer surface of the rotating rod 211.
[0028] Further reading Figure 4In this embodiment, the front of the rear cabinet door 11 is provided with a sliding groove, the outer surface of the back of the connecting block 22 is slidably connected to the inner wall of the sliding groove, and the left end of the connecting block 22 is fixedly connected to a limit block 221.
[0029] During implementation, when maintenance or repair of the internal devices of switch cabinet 1 is required, the rear cabinet door 11 is first rotated 90 degrees to open it. As the rear cabinet door 11 rotates, the connecting block 22 will slide in the inner wall of the slide groove opened on the front of the rear cabinet door 11. When the connecting block 22 slides, it will drive the rotating rod 211 to rotate. As the connecting block 22 moves, it will drive the limiting block 221 to move. When the limiting block 221 moves a certain distance, its top left side will contact the bottom of the plug rod 232.
[0030] Further reading Figure 5 In this embodiment, a square recessed hole is provided on the front of the rear cabinet door 11. A fixing rod 23 is fixedly connected to the inner wall of the square recessed hole. An insert rod 232 is slidably connected to the outer surface of the fixing rod 23. A spring 231 is sleeved on the outer surface of the fixing rod 23. The top of the spring 231 is fixedly connected to the inner wall of the square recessed hole, and the bottom of the spring 231 is fixedly connected to the top of the insert rod 232.
[0031] Further reading Figure 5 In this embodiment, the bottom of the insertion rod 232 and the top left side of the limiting block 221 are both inclined, a handle 233 is fixedly connected to the back of the insertion rod 232, and a slot is provided on the top of the limiting block 221.
[0032] During implementation, since the top left side of the limiting block 221 and the bottom of the insertion rod 232 are both sloped, when the limiting block 221 continues to slide to the left, it will push the insertion rod 232 to slide upward on the outer surface of the fixed rod 23. When the insertion rod 232 slides, it will compress the spring 231, causing it to deform. When the limiting block 221 moves to a certain position, the bottom of the insertion rod 232 will correspond to the slot opened at the top of the limiting block 221. The deformed spring 231 will push the insertion rod 232 downward due to the elastic force, so that the bottom of the insertion rod 232... The surface will insert into the inner wall of the slot to fix the limit block 221, so that the rear cabinet door 11 can be positioned after rotating 90 degrees. This not only ensures that the rear cabinet door 11 will not swing randomly and approach live parts, creating a stable and safe operating space for maintenance and repair personnel, greatly reducing the probability of electric shock accidents, but also keeps the rear cabinet door stationary, avoiding collisions with equipment and lines inside the switch cabinet, protecting the integrity of the equipment shell and the stability of the line connection, and reducing the risk of equipment failure caused by collisions.
[0033] Example 2: This example is based on Example 1, with the addition of a shrinkage component.
[0034] Specifically, in order to provide staff with more operational space, see [reference needed]. Figure 6 and Figure 7 In this embodiment, the shrinking component 3 includes a sliding plate 31, the inner wall of the sliding plate 31 is slidably connected to the outer surface of the rear cabinet door 11, the inner wall of the sliding plate 31 is rotatably connected to a bidirectional threaded rod 32, and the right end of the rear cabinet door 11 is fixedly connected to two fixing blocks 33.
[0035] Further reading Figure 6 In this embodiment, the outer surface of the bidirectional threaded rod 32 is threaded with two moving blocks 321. The ends of the two moving blocks 321 that are far apart from each other are fixedly connected with limit rods. The ends of the two fixed blocks 33 that are close to each other are provided with circular insertion holes. The front of the sliding plate 31 is provided with two sliding grooves. The outer surface of the back of the two moving blocks 321 is slidably connected to the inner wall of the sliding grooves on the same side.
[0036] Further reading Figure 7 In this embodiment, a worm gear 34 is rotatably connected to the inner wall of the sliding plate 31, a rotating block 341 is fixedly connected to the back of the worm gear 34, and a worm wheel 342 is meshed with the right side of the worm gear 34. The inner wall of the worm wheel 342 is fixedly connected to the outer surface of the bidirectional threaded rod 32.
[0037] During implementation, when the rear cabinet door 11 is opened, the sliding plate 31 is pushed to slide on the outer surface of the rear cabinet door 11 so that it can overlap with the rear cabinet door 11. When the sliding plate 31 slides to the leftmost position, the rotating block 341 is rotated clockwise to drive the worm gear 34 to rotate in the inner wall of the sliding plate 31. During the clockwise rotation of the worm gear 34, it will drive the double-threaded rod 32 to rotate clockwise through the worm wheel 342. At the same time, the double-threaded rod 32 will drive the two moving blocks 321 to move away from each other. When the moving block 321 moves to a certain position, the limiting rod fixed at the end away from the worm wheel 342 will be inserted into the inner wall of the circular insertion hole opened on the surface of the corresponding fixed block 33, so that the sliding plate 31 can be fixed in the position overlapping with the surface of the rear cabinet door 11. This not only provides more operating space for the staff, making it easier to carry out equipment inspection and maintenance in a limited space and improving the efficiency of space utilization, but also makes it easier for multiple staff to operate at the rear of the switch cabinet at the same time, improving work efficiency and facilitating cooperation among staff.
[0038] The working principle of this utility model is as follows: When maintenance or repair of the internal device of the switch cabinet 1 is required, the rear cabinet door 11 is first rotated 90 degrees to open it. As the rear cabinet door 11 rotates, the connecting block 22 slides within the inner wall of the groove on the front of the rear cabinet door 11. The sliding of the connecting block 22 causes the rotating rod 211 to rotate. Simultaneously, the moving connecting block 22 causes the limiting block 221 to move. After the limiting block 221 moves a certain distance, its top left side contacts the bottom of the insertion rod 232. Since both the top left side of the limiting block 221 and the bottom of the insertion rod 232 are inclined surfaces, as the limiting block 221 continues to slide to the left, it pushes the insertion rod 232 upwards on the outer surface of the fixed rod 23. The sliding of the insertion rod 232 compresses the spring 231, causing it to deform. When the limit block 221 moves to a certain position, the bottom of the insertion rod 232 will correspond to the slot opened on the top of the limit block 221. The deformed spring 231 will push the insertion rod 232 downward due to the elastic force, so that the outer surface of the bottom of the insertion rod 232 will be inserted into the inner wall of the slot, fixing the limit block 221 and positioning the rear cabinet door 11 in the position after rotating 90 degrees. This not only ensures that the rear cabinet door 11 will not swing randomly and approach live parts, creating a stable and safe operating space for maintenance and repair personnel and greatly reducing the probability of electric shock accidents, but also keeps the rear cabinet door stationary, avoiding collisions with equipment and lines inside the switch cabinet, protecting the integrity of the equipment shell and the stability of the line connection, and reducing the risk of equipment failure caused by collisions.
[0039] When the rear cabinet door 11 is opened, the sliding plate 31 is pushed to slide on the outer surface of the rear cabinet door 11 so that it can overlap with the rear cabinet door 11. When the sliding plate 31 slides to the leftmost position, the rotating block 341 is rotated clockwise to drive the worm gear 34 to rotate in the inner wall of the sliding plate 31. During the clockwise rotation of the worm gear 34, it will drive the double-threaded rod 32 to rotate clockwise through the worm wheel 342. At the same time, the rotation of the double-threaded rod 32 will drive the two moving blocks 321 to move away from each other. When the moving block 321 moves to a certain position, the limiting rod fixed at the end away from the worm wheel 342 will be inserted into the inner wall of the circular insertion hole opened on the surface of the corresponding fixed block 33, so that the sliding plate 31 can be fixed in the position overlapping with the surface of the rear cabinet door 11. This not only provides more operating space for the staff, making it easier to carry out equipment inspection and maintenance in a limited space, thus improving the efficiency of space utilization, but also makes it easier for multiple staff to operate at the rear of the switch cabinet at the same time, improving work efficiency and facilitating cooperation among staff.
