Technical Field

[0001] This utility model belongs to the field of power distribution cabinet technology, specifically a power distribution cabinet for expanding the capacity of a factory refrigeration power system. Background Technology

[0002] Because factory buildings are typically large spaces with many pieces of equipment, and the production process generates a lot of heat, indoor temperatures rise in summer. This not only affects workers' work efficiency and health but may also have an adverse impact on the normal operation of production equipment. Therefore, an efficient and reliable cooling power system is key to maintaining a suitable temperature in the factory. Factory cooling power systems generally require the use of distribution cabinets, which control the factory cooling power system through internal control modules.

[0003] During the use of power distribution cabinets for factory refrigeration power systems, if the capacity is too large, it will easily occupy a lot of space; if the capacity is too small, it will easily prevent the installation of some electrical components. Since the capacity inside the power distribution cabinet is determined after production, it is difficult to expand or reduce the capacity according to the actual situation, resulting in insufficient flexibility in use. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a power distribution cabinet for expanding the capacity of a factory refrigeration power system. This solves the problem that the capacity of the existing power distribution cabinets for factory refrigeration power systems is fixed after production, making it difficult to expand or reduce the capacity according to the actual situation, resulting in insufficient flexibility in use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a power distribution cabinet for expanding the capacity of a factory refrigeration power system, comprising an upper cabinet, a lower cabinet at the bottom of the upper cabinet, a box fixedly connected to the lower cabinet, a bidirectional lead screw rotatably connected inside the box via bearings, two square moving blocks threadedly connected to the bidirectional lead screw, the square moving blocks being located inside the box, a connecting rod rotatably connected to the top of the square moving blocks, the number of connecting rods being two, and a connecting plate rotatably connected to the top of the two connecting rods;

[0006] The connecting plate is fixed to the upper cabinet, and a first U-shaped plate is fixedly connected inside the lower cabinet. Two first sliding strips are fixedly connected to both sides of the first U-shaped plate. Two first sliding grooves are opened on both sides of the inner wall of the upper cabinet. The first sliding strips are located inside the first sliding grooves, and the first sliding grooves are slidably connected to the first sliding strips.

[0007] As a further embodiment of this utility model: dustproof nets are fixedly connected to both sides of the lower cabinet, and a knob is fixedly connected to one end of the bidirectional screw, with several grooves provided on the knob.

[0008] As a further embodiment of this utility model: the upper cabinet body is rotatably connected to an upper cabinet door via a hinge, and the lower cabinet body is rotatably connected to a lower cabinet door via a hinge.

[0009] As a further embodiment of this utility model: a handle is fixedly connected to the lower cabinet door, and the handle has an arc surface design.

[0010] As a further embodiment of this utility model: a second U-shaped plate is fixedly connected inside the lower cabinet door, and a second sliding strip is fixedly connected to both sides of the second U-shaped plate.

[0011] As a further embodiment of this utility model: a second sliding groove is provided on both sides of the inner wall of the upper cabinet door, the second sliding strip is located inside the second sliding groove, and the second sliding strip is slidably connected to the second sliding groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] The expansion distribution cabinet for the factory's refrigeration power system is equipped with an upper cabinet, connecting rods, a double-acting screw, square moving blocks, and a connecting plate. When the height of the upper cabinet needs to be adjusted, turning the knob drives the double-acting screw to rotate. Because the threads on both sides of the double-acting screw are in opposite directions, and the two square moving blocks are threaded onto opposite threaded areas on the double-acting screw, the rotation of the double-acting screw causes the two square moving blocks to move closer or further apart. When the two square moving blocks move closer, they push the connecting plate upwards via the connecting rod. When the two square moving blocks move further apart, they pull the connecting plate downwards via the connecting rod. The connecting plate then moves the upper cabinet up and down, thereby adjusting the height of the upper cabinet. This distribution cabinet facilitates height adjustment of the upper cabinet, allowing for capacity expansion or reduction according to actual needs and improving operational flexibility.

[0014] The expansion of the power distribution cabinet for the factory's refrigeration power system involves the installation of a first U-shaped plate, a second U-shaped plate, a first sliding bar, a first sliding groove, a second sliding groove, and a second sliding bar. When the upper cabinet moves up and down, the first sliding groove and the first sliding bar slide relative to each other, and the second sliding groove and the second sliding bar also slide relative to each other. The first sliding groove and the first sliding bar serve to limit and guide the movement of the upper cabinet, while the second sliding groove and the second sliding bar serve to limit and guide the movement of the upper cabinet door. The dustproof net prevents dust from entering the interior of both the upper and lower cabinets. By limiting and guiding the movement of the upper cabinet and the upper cabinet door, the stability and accuracy of their movement are effectively improved. The first U-shaped plate and the second U-shaped plate ensure the airtightness of the interior of the upper and lower cabinets after expansion, and the dustproof net effectively prevents dust from entering the interior of the upper and lower cabinets, preventing damage to electrical components due to excessive dust.

[0021] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0022] like Figure 1-5 As shown, this utility model provides a technical solution: a power distribution cabinet for expanding the capacity of a factory refrigeration power system, including an upper cabinet 1, a lower cabinet 2 at the bottom of the upper cabinet 1, and dustproof nets 3 fixedly connected to both sides of the lower cabinet 2. The dustproof nets 3 effectively prevent dust from entering the interior of the upper cabinet 1 and the lower cabinet 2, preventing damage to electrical components due to excessive dust. A knob 12 is fixedly connected to one end of a bidirectional lead screw 10. The knob 12 has several grooves, which can increase the... Friction facilitates the rotation of knob 12, improving ease of operation. A box 9 is fixedly connected to the lower cabinet 2. Inside the box 9, a bidirectional lead screw 10 is rotatably connected via bearings. Because of the bidirectional lead screw 10, and the opposite thread directions on both sides of the bidirectional lead screw 10, and the two square moving blocks 14 are respectively threaded onto the opposite thread areas on the bidirectional lead screw 10, it is easy to move the two square moving blocks 14 closer or further apart when the bidirectional lead screw 10 rotates. Two square moving blocks 14 are threaded onto the bidirectional lead screw 10.

[0023] The square movable block 14 is located inside the box body 9. The top of the square movable block 14 is rotatably connected to the connecting rod 13. There are two connecting rods 13. The top of the two connecting rods 13 is rotatably connected to the connecting plate 11. The connecting plate 11 is fixed to the upper cabinet body 1. The lower cabinet body 2 is fixedly connected to the first U-shaped plate 4. The lower cabinet door 7 is fixedly connected to the second U-shaped plate 6. Because of the second U-shaped plate 6 and the first U-shaped plate 4, the first U-shaped plate 4 and the second U-shaped plate 6 can ensure the sealing of the upper cabinet body 1 and the lower cabinet body 2 after expansion. The second U-shaped plate 6 is fixedly connected to the second sliding strip 18 on both sides.

[0024] Two first slide bars 16 are fixedly connected to both sides of the first U-shaped plate 4. Two first slide grooves 15 are opened on both sides of the inner wall of the upper cabinet 1. The first slide bars 16 are located inside the first slide grooves 15. The second slide grooves 17 are opened on both sides of the inner wall of the upper cabinet door 5. The second slide bars 18 are located inside the second slide grooves 17. The second slide bars 18 are slidably connected to the second slide grooves 17.

[0025] The first slide groove 15 is slidably connected to the first slide bar 16. The upper cabinet 1 is rotatably connected to the upper cabinet door 5 via a hinge, and the lower cabinet 2 is rotatably connected to the lower cabinet door 7 via a hinge. The lower cabinet door 7 is fixedly connected to a handle 8. Because the handle 8 is provided, the handle 8 provides a gripping point, making it convenient for people to hold the handle 8 to open the lower cabinet door 7, thus improving the ease of operation. The handle 8 is a curved surface design.

[0026] The working principle of this utility model is as follows:

[0027] When the height of the upper cabinet 1 needs to be adjusted, the knob 12 is turned to rotate the double-acting screw 10. Since the threads on both sides of the double-acting screw 10 are in opposite directions, and the two square moving blocks 14 are threaded onto opposite threaded areas on the double-acting screw 10, the rotation of the double-acting screw 10 will cause the two square moving blocks 14 to move closer or further apart. When the two square moving blocks 14 move closer, they will push the connecting plate 11 upward through the connecting rod 13. When the two square moving blocks 14 move further apart, they will pull the connecting plate 11 upward through the connecting rod 13. When the upper cabinet 1 moves down, the connecting plate 11 will drive the upper cabinet 1 to move up and down, thereby adjusting the height of the upper cabinet 1. The capacity can be expanded or reduced by adjusting the height of the upper cabinet 1. When the upper cabinet 1 moves up and down, the first slide rail 15 and the first slide bar 16 slide relative to each other, and the second slide rail 17 and the second slide bar 18 slide relative to each other. The first slide rail 15 and the first slide bar 16 can play a role in limiting and guiding the upper cabinet 1, and the second slide rail 17 and the second slide bar 18 can play a role in limiting and guiding the upper cabinet door 5. The dustproof net 3 can play a role in preventing dust inside the upper cabinet 1 and the lower cabinet 2.
