[0023] Embodiment

[0024] Reference Figures 1 - 6 A split busbar trunking that is easy to repair, including a busbar trunking housing 1. Inside the cavity of the busbar trunking housing 1, there are several copper bars (not shown in the figure). The busbar trunking housing 1 includes a bottom plate 11. At the four corners of the top end face of the bottom plate 11, support columns 12 are fixedly connected. A side plate 13 is detachably arranged between the two support columns 12. A cover plate 14 is detachably arranged on the top of the bottom plate 11. Locking members 15 are arranged at the connection points of the cover plate 14, the side plate 13 and the support columns 12.

[0025] Reference Figure 6 , the locking member 15 includes a top plate 151. On the left and right sides of the bottom end face of the top plate 151, connecting plates 152 are symmetrically arranged. On the top end face of the top plate 151, a fixed seat 153 with a hollow structure is arranged. A linkage column 154 is slidably arranged inside the fixed seat 153. Between one end of the linkage column 154 and the fixed seat 153, there is a tension spring 155 located inside the cavity of the fixed seat 153. The other end of the linkage column 154 is fixedly connected with a driving rod 156. On the bottom end faces of the driving rod 156 on both sides of the linkage column 154, locking columns 157 whose bottoms extend symmetrically between the two connecting plates 152 are arranged. The locking columns 157 are slidably connected with the top plate 151.

[0026] Specifically, one end of the tension spring 155 is fixedly connected with the linkage column 154, and the other end of the tension spring 155 is fixedly connected with the inner side of the fixed seat 153.

[0027] Furthermore, a first connection groove 121 for inserting the bottom of the connecting plate 152 is provided on the outer side of the top end face of the support column 12. Second connection grooves 141 for inserting the top of one of the connecting plates 152 are symmetrically provided at both ends of the cover plate 14. Third connection grooves 131 for inserting the top of the other connecting plate 152 are symmetrically provided at both ends of the top end face of the side plate 13.

[0028] Furthermore, a first locking groove 142 for inserting one of the locking columns 157 is provided on the top end face of the cover plate 14 outside the second connection groove 141. A second locking groove 132 for inserting the other locking column 157 is provided on the top end face of the side plate 13 inside the third connection groove 131. Through the arrangement of the locking groove 132 and the locking column 157, the connection strength between the side plate 13, the cover plate 14 and the support column 12 is improved.

[0029] Furthermore, a guiding plate 122 is provided on the inner end face of the support column 12. Guiding grooves 133 adapted to the guiding plate 122 are provided on both sides of the side plate 13. Through the arrangement of the guiding groove 133 and the guiding plate 122, guiding connection can be carried out when the side plate 13 and the support column 12 are installed, so that the side plate 13 and the support column 12 are initially fixedly connected.

[0030] Furthermore, a number of fastening columns 134 in a cross-shaped structure are provided on the bottom end face of the side plate 13. Fastening grooves 111 corresponding to the fastening columns 134 one by one are provided on the bottom plate 11 between the two support columns 12. Through the cooperation of the fastening grooves 111 and the fastening columns 134, the connection strength between the side plate 13 and the bottom plate 11 is further enhanced.

[0031] Reinforcing blocks 143 are provided at the four corners of the bottom end face of the cover plate 14. Reinforcing grooves 123 adapted to the reinforcing blocks 143 are provided on the support column 12. Through the arrangement of the reinforcing grooves 123 and the reinforcing blocks 143, the cover plate 14 and the support column 12 are initially fixedly connected.

[0032] The working principle of the present utility model:

[0033] During operation, the operator aligns the guiding slot 133 on the side plate 13 with the guiding plate 122 on the support column 12 for insertion. During the insertion process, the fastening column 134 on the side plate 13 is inserted into the fastening slot 111 on the bottom plate 11, so that the side plate 13 and the bottom plate 11 are initially fixedly connected. Then, the reinforcing block 143 on the cover plate 14 is aligned with the reinforcing slot 123 on the support column 12 for insertion, so that the cover plate 14 and the support column 12 are initially fixedly connected. Then, the operator pulls the driving rod 156 on the locking member 15 to drive the linkage column 154 to stretch the tension spring 155. At the same time, the driving rod 156 drives the locking column 157 to move away from one end of the driving rod 156 until it does not protrude from the bottom end face of the top plate 151. Then, the connecting plate 152 on the locking member 15 is inserted into the ends of the first connecting slot 121, the third connecting slot 131, and the second connecting slot 141 at the connection of the support column 12, the side plate 13, and the cover plate 14. Finally, the driving rod 156 is released. Under the elastic action of the tension spring 155, the tension spring 155 rebounds and resets, thereby driving the end of the locking column 157 away from the driving rod 156 to be inserted into the second locking slot 132 and the first locking slot 142 on the side plate 13 and the cover plate 14, further firmly fixing the bottom plate 11, the side plate 13, and the cover plate 14. When the operator needs to disassemble and repair the copper bar in the busbar housing 1, the locking member 15 can be removed to disassemble the cover plate 14 or any one of the side plates 13 separately, which is convenient for the operator to quickly disassemble and assemble for repair according to needs, saving time, improving work efficiency, and not requiring the operator to carry any tools, reducing the burden and operation difficulty of the operator.

[0034] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "connected" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0035] The above embodiments only represent several implementation manners of the present invention, and the description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
