[0025] Example

[0026] refer to Figures 1-2 A busbar trunking system for quick maintenance includes a busbar trunking housing 1 and a detachable top cover 2 mounted on the top of the busbar trunking housing 1. The top cover 2 is fixed to the busbar trunking housing 1 by snap-fit ​​and screw connection, which enables quick and convenient installation of the top cover 2. The installation process does not require the use of multiple screws for fixing and does not require the use of tools, which greatly reduces the installation process, improves the efficiency of installation and disassembly, and facilitates the maintenance of the lines in the busbar trunking by the staff.

[0027] refer to Figures 5-6 The top cover 2 has an internal groove 201 on one side, and a connecting plate 202 is slidably connected in the internal groove 201. One side of the connecting plate 202 extends to the outside of the internal groove 201, and the other side of the connecting plate 202 is provided with a plurality of evenly distributed springs 203. The top end face of the connecting plate 202 is provided with a drive plate 204 extending to the outside of the top cover 2, and the bottom end face of the other side of the top cover 2 is fixedly connected with a guide plate 205.

[0028] Furthermore, one end of the spring 203 is fixedly connected to the inner wall of the built-in groove 201, and the other end of the spring 203 is fixedly connected to the connecting plate 202.

[0029] Furthermore, the top cover 2 is provided with a displacement groove 209 for the displacement of the drive plate 204. An assist plate 210 is provided on one side of the top cover 2 of the displacement groove 209. With the assistance plate 210, when the operator pulls the drive plate 204, the operator can use the assistance plate 210 to assist the operator to operate the drive plate 204.

[0030] refer to Figures 3-4 The busbar trunking housing 1 includes a base plate 11. A first side plate 12 is fixedly connected to one side of the base plate 11. A connecting groove 121 is provided on the top of the inner side wall of the first side plate 12, which allows one side of the connecting plate 202 to be inserted. A second side plate 13 parallel to the first side plate 12 is fixedly connected to the other side of the base plate 11. A guide groove 131 that fits with the guide plate 205 is provided on the top end face of the second side plate 13. A plurality of mounting seats 132 are fixedly connected to the outer side wall of the second side plate 13. A screw 133 is rotatably provided on the mounting seat 132. A fastening block 134 is screwed onto the screw 133. One end of the fastening block 134 is provided with a fastening thread end 135.

[0031] Furthermore, the top cover 2 is fixedly connected to a first fastening seat 206 corresponding to the screw 133 on the side near the guide plate 205. The first fastening seat 206 has a first opening groove 207 that can be engaged after the screw 133 rotates. The top of the first opening groove 207 has a fastening thread groove 208 that communicates with it and is adapted to the fastening thread end 135.

[0032] Furthermore, a second fastening seat 136 is fixedly connected to the outer wall of the second side plate 13 at the bottom of the mounting base 132. The second fastening seat 136 has a through-hole groove 137 that allows the screw 133 to be engaged after rotation. The inner wall of the second groove 137 is provided with a rubber layer. The rubber has high elasticity and wear resistance, which can realize the engagement and fixation or separation of the screw 133 and the second fastening seat 136.

[0033] The inner wall of the first side plate 12 at the bottom of the connecting groove 121 is provided with a support plate 122. The top end face of the support plate 122 is at the same level as the top end face of the second side plate 13. By setting the support plate 122, it can support the side of the top cover 2 near the connecting plate 202 when the top cover 2 is initially installed, maintain the balance of the top cover 2, and ensure that the connecting plate 202 is aligned with the connecting groove 121 on the busbar trough shell 1.

[0034] The end of the screw 133 away from the mounting base 132 is fixedly connected to a limiting plate 138. The limiting plate 138 ensures that the fastening block 134 always maintains a connection with the screw 133, which facilitates the installation work and prevents the loss of parts.

[0035] The working principle of this utility model:

[0036] When inspecting the lines in the busbar trunking, the top cover 2 needs to be disassembled. First, rotate the fastening block 134 to move it upward on the screw 133 until the fastening thread end 135 is completely disengaged from the fastening thread groove 208. Then, rotate the screw 133 to engage it in the second opening groove 137 on the second fastening seat 136. At this time, the top cover 2 is released from its fixed connection with the busbar trunking shell 1. Then, pull the drive plate 204 to move towards the assist plate 210 in the displacement groove 209. The drive plate 204 drives the connecting plate 202 to move synchronously. At the same time, the spring 203 is compressed and undergoes elastic deformation until the connecting plate 202 is completely retracted into the inner groove 201. At this time, the top cover 2 is released from its engagement with the busbar trunking shell 1. Finally, move the top cover 2 upward to disengage it from the busbar trunking shell 1, and then release the drive plate 204. The elastic potential energy of the spring 203 is released, and it recovers its deformation.

[0037] After maintenance, the top cover 2 needs to be installed. First, pull the drive plate 204 to move towards the assist plate 210 within the displacement groove 209. The drive plate 204 drives the connecting plate 202 to move synchronously, while the spring 203 is compressed and undergoes elastic deformation until the connecting plate 202 is completely retracted into the inner groove 201. Then, align the guide plate 205 on the top cover 2 with the guide groove 131 on the busbar trunking housing 1 and insert it, so that the top cover 2 and the busbar trunking housing 1 are initially connected. At this time, the inner groove 201 on the top cover 2 is connected to the connecting groove 121 on the busbar trunking housing 1. When the drive plate 204 is released, the elastic potential energy of the spring 203 is released, thus restoring its deformation. This causes one side of the connecting plate 202 to engage with the connecting groove 121 on the busbar housing 1, further strengthening the connection between the top cover 2 and the busbar housing 1. Then, the screw 133 is rotated into the first opening groove 207 on the first fastening seat 206. Finally, the fastening block 134 is rotated and moves downward on the screw 133 until the fastening thread end 135 is screwed into the fastening thread groove 208. This allows the top cover 2 to be fixedly installed on the busbar housing 1, and the installed top cover 2 is stable and reliable.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0039] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
