Technical Field
[0001] This utility model relates to the field of busbar technology, specifically a busbar with a deformation-resistant and reinforced structure. Background Technology
[0002] Busbar trunking is a closed connection device containing multiple sets of copper busbars. It is often installed next to power distribution cabinets to replace cables, distribute power to various components, and transmit a large amount of current at a time. The metal busbar trunking also has flame-retardant and impact-resistant properties.
[0003] This power distribution mechanism offers higher cable safety and stronger short-circuit load capacity than previous cables. It is easy to install and disassemble, and the position of the connecting lines can be changed to accommodate adjustments to the power distribution system. However, this type of busbar trunking is only protected by the frame and the front cover, lacking an internal reinforcement structure, making it susceptible to deformation due to compression.
[0004] Now, a novel busbar trunking with a deformation-resistant and reinforced structure is proposed to solve the above problems. Utility Model Content

Four sets of copper busbars are arranged between the two sides inside the outer frame, and connecting pieces are fixed to both sides of the copper busbars, with wire holes in the connecting pieces. Limiting blocks are inserted between the upper and lower parts inside the copper busbars, and four sets of retaining sleeves are arranged between the upper and lower parts behind the limiting blocks. The top and bottom of the limiting blocks are respectively provided with receiving grooves, and inserts are movably inserted into the receiving grooves. Slots are respectively provided at the upper and lower parts inside the outer frame, and sleeves are fixed in the slots. A lever is fixed to the front end of the insert. A slot is provided at the front end of the receiving groove, and a short rod is fixed between the upper and lower parts inside the slot.

[0007] As a further technical solution of this utility model, the spring is sleeved on the outside of the short rod, and the lever can move vertically along the slot.
[0008] As a further technical solution of this utility model, the insert can be embedded in the sleeve block, and the insert can vertically enter and exit the storage slot.
[0009] As a further technical solution of this utility model, the front end of the outer frame is movably sleeved with a cover, and the four corners inside the cover are respectively provided with through grooves, the through grooves are movably connected with a stop block, the side of the through grooves are movably embedded with a ball, the front end of the through grooves is provided with a screw hole, and a fastening bolt is installed in the screw hole.
[0010] As a further technical solution of this utility model, the fastening bolt can abut against the stop block in the through groove, and the stop block can be arranged above and below the two sides of the outer frame.
[0011] As a further technical solution of this utility model, the ball can move left and right in accordance with the groove on the surface of the outer frame, and the outer frame and the cover are on the same horizontal plane.
[0012] As a further technical solution of this utility model, a cylindrical body is fixed at the upper and lower parts of the left and right sides of the outer frame, and a support rod is movably connected inside the cylindrical body. A connecting seat is longitudinally fixed on the outer side between the support rods. A circular groove is provided at the center of the connecting seat. A collar is fixed on the side of the cylindrical body. A positioning bolt is threaded into the hole at the front end of the collar. A spring is welded between the collar and the connecting seat.

[0026] Specifically, such as Figure 1 and Figure 2 As shown, the finger presses the lever 20 at the front end of the limiting block 3, moves the lever 20 and the insert 14 along the short rod 19 at the front end of the slot 17 until the insert 14 is inserted into the storage slot 16, and then the limiting block 3 is inserted into the outer frame 1, so that the four sets of sleeves 4 are respectively sleeved on the outside of the copper busbar 2. After releasing the lever 20, the spring 2 18 is allowed to reset the lever 20 and the insert 14 until the insert 14 is embedded in the sleeve 15 of the slot 5 for fixation.
[0027] The front end of the outer frame 1 is movably fitted with a cover 13, and the four corners inside the cover 13 are respectively provided with through grooves 22. A stop block 23 is movably connected in the through groove 22. A ball bearing 21 is movably embedded in the side of the through groove 22. A screw hole 25 is provided at the front end of the through groove 22, and a fastening bolt 24 is installed in the screw hole 25.
[0028] The fastening bolt 24 can abut against the stop block 23 in the through groove 22. The stop block 23 can be arranged above and below the two sides of the outer frame 1. The ball bearing 21 can move left and right in accordance with the sliding groove on the surface of the outer frame 1. The outer frame 1 and the cover 13 are on the same horizontal plane.
[0029] Specifically, such as Figure 1 and Figure 3 As shown, a cover 13 is fitted between the upper and lower surfaces of the outer frame 1. With the lubrication of the ball bearings 21 at the four corners of the inner wall of the cover 13, the cover 13 can be guided to slide left and right on the surface of the outer frame 1 until the cover 13 completely covers the front end of the outer frame 1 for protection. The stop block 23 is pressed down in the through groove 22, and then the fastening bolt 24 in the front screw hole 25 is used to tighten the stop block 23, and the outer frame 1 is locked from the four corners.
[0030] The outer frame 1 has cylinders 26 fixed at the top and bottom of the left and right sides. Support rods 6 are movably connected inside the cylinders 26. Connecting seats 7 are longitudinally fixed on the outer side between the support rods 6. A circular groove 8 is provided at the center of the connecting seat 7. A collar 28 is fixed on the side of the cylinder 26. A positioning bolt 27 is threaded into the hole at the front end of the collar 28.

Then, the limiting blocks 3 are respectively inserted into the outer frame 1, so that the four sets of sleeves 4 are respectively fitted onto the outside of the copper busbar 2. After releasing the lever 20, the spring 2 18 is allowed to reset the lever 20 and the insert 14 until the insert 14 is embedded into the sleeve 15 of the slot 5 for fixation. A cover 13 is fitted between the upper and lower surfaces of the outer frame 1. With the lubrication of the ball bearings 21 at the four corners of the inner wall of the cover 13, the cover 13 can be guided to the outer frame 1. The surface slides left and right until the cover 13 completely covers the front end of the outer frame 1 for protection. The stop block 23 is pressed down in the through groove 22, and then the stop block 23 is tightened by the fastening bolt 24 in the front screw hole 25.
