Technical Field

[0001] This utility model relates to the field of busbar technology, and in particular to a busbar that can be installed quickly. Background Technology

[0002] In power transmission systems, busbar trunking, as a key piece of equipment for indoor low-voltage power transmission, is gradually replacing traditional wires and cables. It consists of a metal casing, conductive bars, and insulation materials, and can efficiently distribute large amounts of power to components in distributed systems. Within the related technical fields of busbar trunking…

[0003] While existing technologies such as patent CN215681700U have promoted the development of busbar trunking to some extent, many challenges remain in the installation process. The installation process of traditional busbar trunking is extremely cumbersome. For example, connecting the busbar trunking with screws requires workers to repeatedly tighten and loosen the screws and nuts in a confined space. This is inconvenient and time-consuming, greatly reducing installation efficiency. In large-scale projects such as buildings or factories that require a large number of busbar trunking installations, this can severely delay the construction schedule. Utility Model Content

[0025] Reference Figure 1-4 This utility model provides a quick-installation busbar trunking, which includes an outer jacket plate 1. An upper sliding cover 2 is movably connected to the upper end of the outer jacket plate 1. Multiple symmetrical positioning holes 4 are provided on the side of the outer jacket plate 1, which are symmetrically distributed at equal intervals.

[0026] Specifically: Symmetrical limiting and stabilizing strips 7 are fixedly connected to the side of the outer jacket plate 1. The limiting and stabilizing strips 7 are fitted with irregularly shaped sliding pieces 3 that are movably connected and can slide flexibly along the limiting and stabilizing strips 7.

[0027] Specifically: the upper end of the irregular slitting plate 3 is fixedly connected to a corresponding support frame 5, the lower end of the support frame 5 is fixedly connected to a limit rod 12, and a positioning bushing 13 is movably connected on the limit rod 12.

[0028] Specifically: the side of the positioning bushing 13 is fixedly connected with a corresponding paddle 11, the positioning bushing 13 is movably connected to the positioning hole 4, the upper end of the positioning bushing 13 is movably connected to a first return spring 14, and the other end of the first return spring 14 is movably connected to the support frame 5, so as to ensure that the positioning bushing 13 automatically engages with the positioning hole 4 to achieve locking when there is no external force.

[0029] Specifically: the upper end of the support frame 5 is fixedly connected to a hanger rod 6, and the upper end of the outer plate 1 is movably connected to multiple symmetrical connecting blocks 20. The connecting blocks 20 are respectively provided with mounting rings 21, which are movably connected to the hanger rod 6.

[0030] Specifically: The upper end of the mounting ring 21 is fixedly connected with a tightening screw ring 15, and a tightening nut 10 is fitted on the tightening screw ring 15 to achieve quick tightening of the hanger rod 6 in cooperation with the tightening screw ring 15.

[0031] Specifically: a connecting sleeve 8 is fixedly connected to the side of the connecting block 20, and a connecting rod 9 is fixedly connected to the side of the connecting block 20. The connecting sleeve 8 is movably connected to the connecting rod 9, and multiple reserved holes 16 are provided on the connecting sleeve 8.

[0032] Specifically: a pressing hole 17 is provided inside the connecting rod 9, a positioning cap 19 is movably connected inside the pressing hole 17, the positioning cap 19 is movably connected to the reserved hole 16, a second return spring 18 is movably connected inside the pressing hole 17, and one end of the second return spring 18 is movably connected to the positioning cap 19, so as to realize the quick positioning of the connecting sleeve 8 and the connecting rod 9.

[0033] Working principle:

[0034] During installation, the connection between the outer sleeve plate 1 and the upper sliding cover 2 is addressed first. Guided by stainless steel slide rails on both sides, the upper sliding cover 2 can smoothly slide and open on the upper end of the outer sleeve plate 1, facilitating subsequent operation and maintenance of the busbar trunking. During the busbar trunking positioning and installation phase, the irregularly shaped sliding piece 3 is operated to slide along the limiting and stabilizing strip 7, causing the support frame 5, limiting rod 12, positioning bushing 13, and other components to move. When the busbar trunking needs to be fixed in position, the lever 11 is moved to overcome the elasticity of the first return spring 14, pulling the positioning bushing 13 out of the positioning hole 4. After adjusting the position of the busbar trunking, the lever 11 is released, and the first return spring 14 pushes the positioning bushing 13 to automatically engage with the positioning hole 4, completing the horizontal positioning and fixing of the busbar trunking. For the hoisting and installation of the busbar trunking, the lifting rod 6 is passed through the mounting ring 21. By rotating the tightening nut 10, it quickly secures the lifting rod 6 to the connecting block 20 through the threaded engagement with the tightening ring 15, achieving stable hoisting of the busbar trunking. The height of the lifting rod 6 can be adjusted according to actual needs. When multiple busbar trunkings need to be connected, the connecting sleeve 8 and the connecting rod 9 come into play. Pressing the positioning cap 19 compresses the second return spring 18, causing the positioning cap 19 to disengage from the pre-drilled hole 16. At this time, the connecting sleeve 8 can be slid along the connecting rod 9 to adjust its position. After aligning with the appropriate pre-drilled hole 16, the positioning cap 19 is released. The second return spring 18 pushes the positioning cap 19 back into the pre-drilled hole 16, achieving rapid splicing and positioning of two busbar trunkings. The entire process requires no complicated tools or operations, greatly improving the installation efficiency of the busbar trunking, and the connection is stable and reliable.

[0035] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
