[0002] Electrical cabinets are crucial load-bearing and protective devices for electrical components. They house various electrical components such as circuit breakers, contactors, relays, and terminal blocks, connected by numerous cables to achieve complex control functions. Currently, when wiring the circuit boards in electrical cabinets, workers often need to temporarily place them at the bottom of the cabinet or use simple external supports. The position and angle of the circuit boards cannot be flexibly adjusted according to wiring requirements, forcing workers to bend over or turn sideways. This not only increases the labor intensity for wiring personnel but also increases wiring time and reduces wiring quality. Furthermore, the weight and size of the wired circuit boards make it difficult to place them into the pre-set slide rails inside the electrical cabinet. Summary of the Invention

[0003] The purpose of this utility model is to provide a wiring bracket for electrical cabinets, so as to overcome the problems in the prior art of the electrical board being difficult to wire and the electrical board being inconvenient to install into the electrical cabinet.

Wheels are mounted on the bottom of the base. The junction plate is mounted on the base via a lifting frame, which drives the junction plate to move up and down relative to the base. A rotating structure is installed between the junction plate and the lifting frame, which drives the junction plate to rotate up and down relative to the lifting frame. The junction plate includes at least one crossbeam. The positioning component includes a top plate, with side plates mounted on both sides of the top plate. Positioning threaded holes are formed on the side plates, into which positioning bolts are inserted. Multiple rollers are spaced along the length of the bottom of the junction plate.

[0017] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort should fall within the scope of protection of this utility model.

[0018] A junction box for an electrical cabinet includes a base 1, a junction plate 2, and a positioning component. The base 1 is equipped with wheels 8 at its bottom. The present invention can be moved by installing wheels 8 at the bottom of the base 1. The wheels 8 are omnidirectional wheels.

[0019] The terminal block 2 is installed on the front side of the base 1. The base 1 has a counterweight 31 on the rear side of the terminal block 2. By setting the counterweight 31, the present invention can be made more comfortable to use. The base 1 also has a storage box on the rear side of the terminal block 2, which can be used to store items.

[0020] The terminal block 2 is mounted on the base 1 via a lifting frame. The lifting frame can drive the terminal block 2 to move up and down relative to the base 1. The lifting frame includes a lifting telescopic cylinder 29 and left and right fixed cylinders 26. The left and right fixed cylinders 26 are fixedly mounted on the front end of the base 1. Lifting rods 27 are inserted into the fixed cylinders 26. The tops of the two lifting rods 27 are respectively connected to the terminal block 2. The upper ends of the two lifting rods 27 are connected via a lifting plate 28. The lifting telescopic cylinder 29 is mounted on the base 1, and the piston rod of the lifting telescopic cylinder 29 is fixedly connected to the lifting plate 28.

[0021] This utility model uses a lifting frame to drive the terminal block 2 to move up and down. During lifting, the lifting telescopic cylinder 29 is first activated, which drives the lifting plate 28 to move up and down. The lifting plate 28 drives the terminal block 2 to move up and down through the lifting rods 27 on both sides.

[0022] A rotating structure is installed between the terminal block 2 and the lifting frame. The rotating structure can drive the terminal block 2 to rotate up and down relative to the lifting frame. The tops of the lifting rods 27 on both sides are rotatably connected to the terminal block 2 through rotating shafts. The rotating structure includes a rotating telescopic cylinder 30. The bottom of the rotating telescopic cylinder 30 is rotatably connected to the lifting plate 28. The piston rod of the rotating telescopic cylinder 30 is rotatably connected to the terminal block 2.

[0023] The rotating structure described in this invention can drive the terminal block 2 to rotate up and down. During rotation, the rotating telescopic cylinder 30 is first activated, and the rotating telescopic cylinder 30 drives the terminal block 2 to rotate through the extension and retraction of the piston rod. Rotating ears 33 are respectively installed on the left and right sides of the bottom surface of the telescopic terminal block 2. Both rotating ears 33 extend towards the lifting rod 27, and are rotatably connected to the top of the lifting rod 27 on the same side via rotating shafts. By setting the rotating ears 33, this invention allows the terminal block 2 to be positioned in front of the base 1 when rotated to a vertical position, thus facilitating the movement of the circuit board into the electrical cabinet.

[0024] The terminal block 2 includes at least one crossbeam 4 and a square frame 9. The crossbeam 4 is installed in the square frame 9. In this utility model, three crossbeams 4 can be installed in the telescopic square frame 9. The top of the lifting rod 27 is rotatably connected to the crossbeam 4, and the piston rod of the telescopic rod is rotatably connected to the crossbeam 4.

[0025] The wiring board 2 has transverse sliding grooves 10 at its left and right ends respectively. A transverse extension bar 11 is installed in the transverse sliding grooves 10 on both sides respectively. The outer end of the transverse extension bar 11 is fixedly connected to the transverse extension longitudinal bar 12. A transverse fixing threaded hole is opened at the outer end of the transverse sliding grooves 10 on both sides. A transverse fixing bolt 13 is inserted into the transverse fixing threaded hole. A transverse guide hole 14 is opened along the length direction of the transverse sliding groove 10. A transverse guide block 15 is installed on the inner side of the transverse extension bar 11 and inserted into the transverse guide hole 14.

[0026] The terminal block 2 of this invention has two transverse sliding grooves 10 at both its left and right ends, and the transverse extension rod 11 can slide left and right along the transverse sliding grooves 10. By installing the transverse extension rod 11 and the transverse extension rod 12 on the left and right sides of the terminal block 2 respectively, the left and right transverse length of the terminal block 2 can be increased. When it is necessary to increase the left and right length of the terminal block 2, we only need to pull the transverse extension rod 11 outward. When the transverse extension rod 11 moves outward to the predetermined position, we can rotate the transverse fixing bolt 13. The transverse fixing bolt 13 moves inward and abuts against the transverse extension rod 11, thereby achieving the purpose of fixing the transverse extension rod 11. This invention, by setting the transverse guide hole 14, can prevent the transverse extension rod 11 from moving out of the transverse sliding groove 10. When the transverse extension rod 11 moves outward to the maximum distance, the transverse guide block 15 will contact the outer end of the transverse guide hole 14 and prevent the transverse extension rod 11 from continuing to move outward.

[0027] The rear end of the terminal block 2 is provided with a longitudinal groove 16, and a longitudinal extension rod 17 is installed in the longitudinal groove 16. The upper end of the longitudinal extension rod 17 is fixedly connected to a longitudinal extension crossbar 18. The outer end of the longitudinal groove 16 is provided with a longitudinal fixing threaded hole, and a longitudinal fixing bolt 19 is inserted into the longitudinal fixing threaded hole. The longitudinal groove 16 is provided with a longitudinal guide hole 20 along its length direction, and a longitudinal guide block 21 inserted into the longitudinal guide hole 20 is installed on the inner side of the longitudinal extension rod 17.

[0028] The longitudinal extension rod 17 of this invention can move along the longitudinal groove 16, and the rear end of the terminal block 2 has two longitudinal grooves 16. By installing the longitudinal extension rod 17 at the rear end of the terminal block 2, the vertical length of the terminal block 2 can be increased. When it is necessary to increase the vertical length of the terminal block 2, we only need to pull the longitudinal extension rod 17 outward. When the longitudinal extension rod 17 moves outward to the predetermined position, we can rotate the longitudinal fixing bolt 19, and the longitudinal fixing bolt 19 moves inward and abuts against the longitudinal extension rod 17, thereby achieving the purpose of fixing the longitudinal extension rod 17. By setting the longitudinal guide hole 20, this invention can prevent the longitudinal extension rod 17 from moving out of the longitudinal groove 16. When the longitudinal extension rod 17 moves outward to the maximum distance, the longitudinal guide block 21 will contact the outer end of the longitudinal guide hole 20 and prevent the longitudinal extension rod 17 from continuing to move outward.

[0029] The front ends of the transverse extension rod 12, the longitudinal extension crossbar 18, the square frame 9, and the crossbeam 4 of this invention are all flush, so that when the circuit board is placed on the terminal block 2, the transverse extension rod 12, the longitudinal extension crossbar 18, the square frame 9, and the crossbeam 4 can all provide support.

[0030] The positioning components can be installed on both sides of the crossbeam 4 to position the circuit board, thereby preventing the circuit board from moving left, right, up, or down on the terminal block 2. The positioning components can also be installed on the horizontal extension bar 11 and the square frame 9. Multiple positioning components can be installed simultaneously on the terminal block 2.

[0031] The positioning component includes a top plate 5, with side plates 6 installed on both sides of the top plate 5. The distance between the two side plates 6 is slightly greater than the width of the crossbeam 4. Positioning threaded holes are provided on the side plates 6, and positioning bolts 7 are inserted into these holes. When the positioning bolts 7 are rotated inward, they abut against the crossbeam 4. This contact between the positioning bolts 7 and the crossbeam 4 achieves relative fixation between the side plates 6 and the crossbeam 4, thus fixing the positioning component relative to the crossbeam 4. The circuit board is sandwiched between the two positioning components, preventing it from moving left or right on the terminal block 2. Positioning threaded holes are provided on both side plates 6 of the positioning component in this invention.

[0032] A support rod 22 is installed on the top plate 5, and a cantilever 23 is installed on the support rod 22. A downward threaded hole is opened on the cantilever 23, and a downward screw 24 is installed in the downward threaded hole. A rubber block 25 is installed at the bottom of the downward screw 24. By setting the downward screw 24, when the rubber block 25 at the bottom of the downward screw 24 comes into contact with the circuit board, the downward screw 24 and the rubber block 25 can effectively restrict the vertical movement of the circuit board.

[0033] The bottom of the terminal block 2 is equipped with multiple rollers 3 at intervals along its length. The rollers 3 of this invention are all installed at the same height and form a row of rollers 3. When wiring, the circuit board is placed on this row of rollers 3. When it is necessary to move the circuit board, the circuit board can be easily moved on this row of rollers 3.

[0034] The working process of this utility model is as follows: When wiring, first place the circuit board or cabinet door on the roller 3 at the bottom of the wiring board 2. At this time, the back of the circuit board will rest against the front end of the wiring board 2. Then, install positioning parts on the left and right sides of the circuit board. When installing the positioning parts, first insert the side plates 6 on the crossbeam 4, then push the positioning parts so that the top plate 5 only touches the circuit board. Rotate the positioning bolt 7 so that the positioning bolt 7 abuts against the crossbeam 4. Finally, rotate the pressing screw 24 so that the pressing screw 24 moves downward and the rubber block 25 abuts against the circuit board. After the circuit board is installed, we can raise the lifting frame and the rotating structure to adjust the height and tilt angle of the circuit board so that the wiring personnel can perform wiring more comfortably.

[0035] When it is necessary to move the circuit board to the electrical cabinet, we can first activate the rotating telescopic cylinder 30. The piston rod of the rotating telescopic cylinder 30 extends forward and drives the terminal block 2 to rotate to a vertical position. Then we push the circuit board to the side of the electrical cabinet and align the circuit board with the circuit board slide rail of the electrical cabinet. At this time, we measure the height of the circuit board slide rail of the electrical cabinet, and then activate the lifting telescopic cylinder 29 to lower the bottom of the circuit board to the same height as the circuit board slide rail. At this time, we rotate the positioning bolt 7 outward so that the positioning bolt 7 does not abut against the crossbeam 4, and remove the positioning part from the crossbeam 4. At this time, we can push the circuit board towards the electrical cabinet. Since the circuit board is placed on a row of rollers 3 at the bottom of the terminal block 2, it is very easy to push.
