Description

Technical Field

[0001] The utility model belongs to the technical field of bus ducts, and particularly relates to a combined bus duct which is convenient to adjust. Background Art

[0002] The bus duct, as an important part of the modern power distribution system, occupies a pivotal position in the power engineering in terms of its design, manufacture and application. The bus duct is an efficient, safe and convenient power transmission device, mainly used in the low-voltage power distribution system, especially playing an irreplaceable role in the power transmission of large capacity and long distance.

[0003] For example, the Chinese patent with the publication number CN214543511U discloses a new type of combined bus duct device, including a bus duct body. An activity groove and an activity plate are arranged in the bus duct body. A cooling fan is arranged on the activity plate. Slide rails are arranged on both sides of the bus duct body, and mounting plates are arranged in the slide rails. By arranging ventilation holes and a cooling fan in the bus duct body, the utility model is convenient for dissipating heat from the metal conductor in the bus duct, and avoids the internal structure damage of the bus duct body caused by overhigh internal temperature during operation.

[0004] The above-mentioned bus duct can flexibly adjust the installation position according to the actual situation, increase its application range and improve the installation efficiency. However, there are still some defects that need to be improved. Specifically, whenever it is necessary to readjust the position of the mounting plate to adapt to the installation of the bus duct body, it is often necessary to re-drill mounting holes in the wall. This step not only consumes time and effort, increases the construction cost, but also causes unnecessary damage to the wall. In addition, the current connection method between the bus duct cover plate and the body generally uses screw fixation. When the conductive copper plate is damaged or other maintenance requirements occur, the process of disassembling the cover plate is particularly cumbersome, increasing the difficulty of maintenance work. Content of the Utility Model

[0005] Aiming at the problems mentioned in the background art, the purpose of the utility model is to provide a combined bus duct which is convenient to adjust, so as to solve the problems in the background art.

[0006] The above technical purpose of the utility model is realized through the following technical solutions:

The insertion blocks are movably connected with the insertion slots. One side of the connecting rod is movably connected with the connection holes. The lower end of the busbar trunking body is in fitting connection with an installation plate. Inside the installation plate, there is a guiding slot opened. Inside the guiding slot, there is a guiding block slidably connected. One end of the guiding block is fixedly connected with the end of the busbar trunking body away from the cover plate. On the installation plate, there is a second power component.

[0008] As a preferred technical solution, the first power component includes a first screw rod which is rotatably connected inside the installation slot and there are two first screw rods. One side of the sliding seat is threadedly connected to the first screw rod. Between the two first screw rods, there is a connecting shaft fixedly connected and the connecting shaft is rotatably connected inside the installation slot. On one side of the connecting shaft, there is a first tooth cone fixedly connected. On one side of the first tooth cone, there is a second tooth cone meshingly connected. On one side of the second tooth cone, there is a driving rod fixedly connected. The driving rod is rotatably connected to the busbar trunking body and one side of the driving rod extends out of the busbar trunking body and is fixedly connected with a first torsion block.

[0009] As a preferred technical solution, the second power component includes a second screw rod which is rotatably connected inside the guiding slot. The guiding block is threadedly connected to the second screw rod. The second screw rod penetrates through one side of the installation plate and is fixedly connected with a second torsion block.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Embodiment

[0021] Refer to Figures 1 to 5, the easily adjustable combined busbar of this embodiment includes a busbar body 1. A conductive copper sheet 3 is placed inside the busbar body 1. A cover plate 2 is movably connected to the upper end of the busbar body 1. On both sides of one end of the busbar body 1, insertion slots 5 are opened. A connecting rod 51 is slidably connected inside the insertion slot 5. One end of the connecting rod 51 is fixedly connected to a sliding seat 52. An installation groove 6 is opened on one side of the busbar body 1 where the insertion slot 5 is located. The sliding seat 52 and the connecting rod 51 are both slidably connected to the installation groove 6. A first power assembly 7 is provided on one side of the sliding seat 52. On both sides of one end of the cover plate 2, insertion blocks 4 are fixedly connected. A connection hole 41 is opened inside the insertion block 4. The insertion block 4 is movably connected to the insertion slot 5. One side of the connecting rod 51 is movably connected to the connection hole 41. An installation plate 8 is adhesively connected to the lower end of the busbar body 1. A guiding groove 9 is opened inside the installation plate 8. A guiding block 10 is slidably connected inside the guiding groove 9. One end of the guiding block 10 is fixedly connected to the end of the busbar body 1 away from the cover plate 2. A second power assembly 11 is provided on the installation plate 8. Through the above settings, the position adjustment process of the busbar body 1 can be more rapid and efficient, which not only saves installation time but also reduces labor costs. For large-scale engineering projects, this improvement in efficiency is particularly significant. The design of quickly disassembling the cover plate 2 enables maintenance personnel to enter the inside of the busbar more quickly for overhauling the conductive copper plate, thereby promptly discovering and solving problems and improving maintenance efficiency.

[0022] Reference Figure 2 , the first power assembly 7 includes a first screw rod 71. The first screw rod 71 is rotatably connected inside the installation groove 6, and there are two first screw rods 71. One side of the sliding seat 52 is threadedly connected to the first screw rod 71. A connecting shaft 72 is fixedly connected between the two first screw rods 71, and the connecting shaft 72 is rotatably connected inside the installation groove 6. A first tooth cone 73 is fixedly connected to one side of the connecting shaft 72. A second tooth cone 74 is meshed and connected to one side of the first tooth cone 73. A driving rod 75 is fixedly connected to one side of the second tooth cone 74. The driving rod 75 is rotatably connected to the busbar body 1, and one side of the driving rod 75 extends out of the busbar body 1 and is fixedly connected to a first torsion block 76; by setting the first power assembly 7, when it is necessary to make the sliding seat 52 drive the connecting rod 51 to move, rotate the first torsion block 76. The first torsion block 76 drives the driving rod 75 to rotate. The driving rod 75 drives the second tooth cone 74 to rotate. The second tooth cone 74 drives the first tooth cone 73 to rotate. The first tooth cone 73 drives the connecting shaft 72 to rotate, so that the first screw rods 71 on both sides can be rotated, thereby driving the sliding seat 52 to drive the connecting rod 51 to move, and making the connecting rod 51 leave the connection hole 41 of the insertion block 4. At this time, the insertion block 4 and the insertion slot 5 are no longer fixed, realizing the function of quickly disassembling the cover plate 2.

[0023] Reference Figures 4 - 5, the second power assembly 11 includes a second screw 111 which is rotatably connected to the inside of the guide groove 9. The guide block 10 is threadedly connected to the second screw 111. The second screw 111 penetrates through one side of the mounting plate 8 and is fixedly connected to a second torsion block 112. One side of the second torsion block 112 is threadedly connected to a third screw 113. One end of the third screw 113 is fixedly connected to a third torsion block 115, and the other end of the third screw 113 is fixedly connected to a fitting pad 114. One side of the fitting pad 114 is movably connected to one side of the mounting plate 8. By providing the second power assembly 11, when it is necessary to adjust the position of the busbar body 1 on the mounting plate 8, rotate the second torsion block 112 to drive the second screw 111 to rotate, and drive the guide block 10 on the surface of the second screw 111 to slide in the guide groove 9, so that the guide block 10 drives the busbar body 1 to move, and the position of the busbar body 1 can be quickly changed without adjusting the position of the mounting plate 8. After the position adjustment of the busbar body 1 is completed, rotate the third torsion block 115 to drive the third screw 113 to rotate, so that the third screw 113 drives the fitting pad 114 to move, and the fitting pad 114 is attached to the mounting plate 8 to increase the frictional resistance and prevent the second screw 111 from rotating, so that the guide block 10 is kept stable in the guide groove 9, and the position of the busbar body 1 can be stabilized. It should be noted that the fitting pad 114 is made of rubber material.

[0024] Reference Figure 4 , both sides of the mounting plate 8 are fixedly connected with fixing blocks 12, and mounting holes 13 are formed in the fixing blocks 12. By connecting the fixing blocks 12 to both sides of the mounting plate 8 and forming the mounting holes 13 in the fixing blocks 12, the mounting plate 8 can be fixed to the wall.

[0025] Principle of use and advantages: When installing this busbar trunking, attach the mounting plate 8 to the wall, pass the screws through the fixing hole 13 of the fixing library at the four corners, and fix the mounting plate 8 on the wall. When it is necessary to finely adjust the busbar trunking body 1, the operator reaches in from the side with the hand to contact the second torsion block 112. The second torsion block 112 drives the second screw 111 to rotate, causing the guiding block 10 to slide in the guiding groove 9 of the mounting plate 8 to adjust the position of the busbar trunking body 1. Thus, the position of the busbar trunking body 1 can be quickly changed without adjusting the position of the mounting plate 8. The operation steps are simple and convenient. After the position adjustment of the busbar trunking body 1 is completed, rotate the third torsion block 115 to drive the third screw 113 to rotate, causing the third screw 113 to drive the fitting pad 114 to move, so that the fitting pad 114 is attached to the mounting plate 8, increasing the frictional resistance to prevent the second screw 111 from rotating, thereby keeping the guiding block 10 stable in the guiding groove 9, and then stabilizing the position of the busbar trunking body 1. When it is necessary to repair and maintain the conductive copper sheet 3, rotate the first torsion block 76. The first torsion block 76 drives the driving rod 75 to rotate, the driving rod 75 drives the second tooth cone 74 to rotate, the second tooth cone 74 drives the first tooth cone 73 to rotate, and the first tooth cone 73 drives the connecting shaft 72 to rotate, so that the first screws 71 on both sides can be driven to rotate, thereby driving the sliding seat 52 to drive the connecting rod 51 to move, causing the connecting rod 51 to leave the connection hole 41 of the plug-in block 4. At this time, the plug-in block 4 and the plug-in slot 5 are no longer fixed, and the cover plate 2 can be removed. There is no need to use tools to disassemble the cover plate 2, and the disassembly is simple and convenient, reducing the difficulty of maintenance work.
