Description

Technical Field

[0001] This utility model relates to the field of busbar technology, and in particular to a busbar with a positioning structure. Background Technology

[0002] Busbar trunking is a closed metal device made of copper or aluminum busbar columns, used to distribute large amounts of power to various components in a distributed system. Busbar trunking is designed as a long and flat channel with multiple conductive strips or conduits inside for transmitting high current. Because busbar trunking has a large conductive cross-sectional area, it can carry high current loads, reduce resistance and losses, and its compact structure occupies little space, making it suitable for installation in limited spaces. Therefore, busbar trunking has increasingly replaced wires and cables in indoor low-voltage power transmission trunk line projects.

[0003] However, in most busbar trunking systems, the top cover is assembled by fastening with bolts or similar fasteners, which makes disassembly and installation quite inconvenient and can easily lead to misalignment.

[0004] Therefore, a busbar trunking with a positioning and installation structure is proposed. Utility Model Content

[0005] (a) Technical problems to be solved To overcome the shortcomings of existing technologies, a busbar trunking with a positioning structure is proposed to solve the problem that most busbar trunkings are currently assembled by fastening with bolts or similar fasteners during the installation of their cover plates, which makes disassembly and installation quite inconvenient and easily causes installation misalignment.

[0006] (II) Technical Solution This utility model is achieved through the following technical solution: This utility model proposes a busbar trunking with a positioning structure, including a busbar trunking body and a cover plate covering its opening, wherein a connector copper busbar is installed inside the busbar trunking body. The busbar trunking body has symmetrical side mounting plates on both sides of its upper end, and several internal cavities are installed on the outer side of the side mounting plates. The upper end of each internal cavity has a through top insertion port. Several fixing posts are provided on both sides of the bottom end face of the cover plate, corresponding one-to-one with the internal cavities. The lower end of each fixing post has an inwardly arranged insertion groove. The inner side of each internal cavity has a through movable sliding groove. A push plate is installed on the outer side of the side mounting plate. Several insertion blocks are provided on the inner side of the push plate and are slidably connected to the movable sliding groove. The insertion blocks have outwardly opening slots that are inserted into the insertion grooves.

[0007] Furthermore, a handle is installed at the top of the cover plate.

[0008] Furthermore, the cover plate has several through-hole ventilation holes inside.

[0009] Furthermore, the inner wall of the internal cavity is provided with a reinforcing groove corresponding to the movable slide groove, which is connected to the inner side of the insertion block.

[0010] Furthermore, both the fixing post and the insertion slot are rectangular in shape.

[0011] Furthermore, a rotating screw is installed through the middle of the push plate, and a knob is provided on the outside of the rotating screw. A threaded hole is provided in the middle of the side mounting plate to connect with the rotating screw.

[0012] (III) Beneficial Effects Compared with the prior art, this utility model has the following advantages: In this invention, by inserting the fixing post at the lower end of the cover plate into the internal cavity, and then pushing the push plate inward to insert the inner insertion block into it, the inner slot of the block engages with the outer insertion slot of the fixing post. In this way, the fixing post is fixed in the internal cavity by force, which can fix the cover plate, making disassembly and assembly more convenient. Moreover, the one-to-one correspondence between the fixing post and the internal cavity makes the installation more accurate, avoids misalignment, and achieves positioning and assembly of the cover plate, resulting in higher work efficiency and reduced disassembly time.

[0013] Furthermore, the knob and rotating screw on the side allow for easy connection with the threaded hole, facilitating a stable setting of the push plate and preventing loosening due to vibration, thus improving the stability of the fixation. Attached Figure Description

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0017] Please see Figures 1-4 This utility model provides a busbar trunking with a positioning structure, including a busbar trunking body 1, a connector copper busbar 2 installed inside the busbar trunking body 1 for installation and operation, and a cover plate 3 covering its opening, so that the upper end of the cover plate 3 is closed during use to prevent damage to the internal components. A handle 4 is installed at the top of the cover plate 3, which makes it easier for the operator to lift the cover plate 3 upwards, making operation more convenient. Several through vent holes 5 are provided inside the cover plate 3 to facilitate heat dissipation.

[0018] The busbar trunking body 1 has symmetrical side mounting plates 6 on both sides of its upper end, allowing for the installation and removal of the cover plate from within, providing sufficient fixing space. Several internal cavities 7 are installed on the outer side of the side mounting plates 6, and these cavities 7 can also be rectangular to facilitate the movement of the insertion block 14 under internal force. The upper end of each internal cavity 7 has a through-hole top insertion port 8. Several fixing posts 9 are provided on both sides of the bottom surface of the cover plate 3, corresponding one-to-one with the internal cavities 7. When the fixing posts 9 are inserted into the internal cavities 7, their bottom surfaces contact the bottom surfaces of the internal cavities 7, ensuring smooth installation. More quickly and stably, the cover plate 3 is positioned by the action of the fixing post 9 and the top insertion port 8, avoiding misalignment during insertion. The fixing post 9 is inserted into the internal cavity 7 through the top insertion port 8, allowing the upper cover plate 3 to close the upper end of the busbar trunking body 1. The lower end of the fixing post 9 has an inwardly oriented insertion groove 10, and both the fixing post 9 and the insertion groove 10 are rectangular. This rectangular design increases the contact area between the slot 15 and the insertion groove 10, facilitating fixed force application. For greater stability during fixing, the internal cavity 7 has a through-type sliding groove 12 on one side, and the sliding groove 12 is at the same level as the insertion groove 10 inside the internal cavity 7, which facilitates direct contact between the insertion blocks 14 when they are inserted. A push plate 13 is installed on the outer side of the side mounting plate 6, and several insertion blocks 14 are provided on the inner side of the push plate 13, which are slidably connected to the sliding groove 12. The number of insertion blocks 14 is the same as that of the fixing post 9 and the internal cavity 7, which facilitates more stable fixing. The insertion blocks 14 have outward openings inside. The slot 15 is inserted into the insertion slot 10 to facilitate the fixing of the fixed post 9 through the slot 15 and the insertion slot 10, preventing it from being pulled upward. The inner wall of the internal cavity 7 is provided with a reinforcing groove 11 corresponding to the moving slide 12, which is connected to the inner side of the insertion block 14. This allows the insertion block 14 to enter the reinforcing groove 11 after the fixed post 9 is inserted and fixed, thus increasing the force-bearing surface of the insertion block 14, making it easier to strengthen the fixing effect of the fixed post 9, resulting in better stability, and also making it easier for the knob 16 to fully push the push plate 13 to move inward. Preferably, a rotating screw 18 is installed through the middle of the push plate 13, which facilitates the movement of the rotating screw 18 within the push plate 13. A knob 16 is provided on the outside of the rotating screw 18, and the knob 16 is larger than the point where the rotating screw 18 passes through the push plate 13. A threaded hole 17 is provided in the middle of the side mounting plate 6 to connect with the rotating screw 18. This allows the rotating screw 18 to rotate in the threaded hole 17 when the knob 16 is turned, enabling it to work inward or outward. When moving inward, the push plate 13 can be fixed to prevent it from becoming loose or unstable due to shaking when fixing the fixing post 9. When moving outward, the push plate 13 can be opened to disassemble the upper cover plate 3, resulting in better performance.

[0019] Working principle: In use, the cover plate 3 is placed downwards by the handle 4, so that the fixing post 9 is inserted into the top insertion port 8 and enters the internal cavity 7. Then, the knob 16 is turned on the other side, so that the rotating screw 18 is rotated in the threaded hole 17 and moves inward during the rotation, thereby pushing the push plate 13 inward. This allows the inner insertion block 14 to enter the internal cavity 7 through the moving slide 12. When it enters, the internal slot 15 engages with the insertion slot 10. Under rotation, it is pushed to contact the reinforcing slot 11, thereby fixing the push plate 13 and fixing the cover plate 3. To disassemble, turn the knob 16 in the opposite direction to loosen the rotating screw 18 and pull the push plate 13 to complete the work.
