Description

Technical Field

[0001] This utility model relates to the field of busbar technology, specifically to a busbar that is easy to connect. Background Technology

[0002] Busbar trunking is an electrical component that replaces cables in the process of connecting circuits. With the emergence of modern engineering facilities and equipment, the electricity consumption of various industries has increased rapidly, especially with the emergence of many high-rise buildings and large factory workshops. Traditional cables, as power transmission conductors, can no longer meet the requirements of high-current transmission systems. The parallel use of multiple cables has brought many inconveniences to on-site installation and construction. Plug-in busbar trunking, as a new type of power distribution conductor, has emerged. Busbar trunking has fireproof and fire-resistant functions and can work continuously in high-temperature environments.

[0003] Existing busbar trunking is typically fixed to other busbar trunking systems using busbar connectors. These connectors use conductive copper plates to connect the two sets of busbar trunking systems. After connection, multiple sets of bolts are used to secure the conductive copper plates, ensuring a tight fit between the plates and one end of the busbar trunking. Because multiple bolts are required, connecting the two sets of busbar trunking systems using connectors consumes a significant amount of manpower and time, resulting in low operator efficiency and impacting assembly efficiency. Therefore, it is necessary to redesign and modify existing busbar trunking systems to facilitate connection and effectively prevent connection difficulties. Utility Model Content

[0004] To address the problems mentioned in the background section, the present invention aims to provide a busbar trunking system that facilitates connection. This system overcomes the limitations of existing busbar trunking systems that typically use busbar connectors for fixing. These connectors connect two busbar trunking systems via conductive copper plates, requiring multiple bolts to secure the conductive copper plates to one end of the busbar trunking. This process necessitates significant manpower and time, leading to low operator efficiency and impacting the overall assembly efficiency of the busbar trunking system.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a busbar trunking system that facilitates docking, comprising a first busbar trunking body, a second busbar trunking body disposed above the first busbar trunking body, sliding grooves provided on both sides of the first and second busbar trunking bodies, and a protective cover movably connected inside the sliding groove, a limit strip fixedly connected to the surface of the protective cover, a support frame fixedly connected to both sides of the first and second busbar trunking bodies, a movable column movably connected inside the support frame, the movable column movably connected to the limit strip, a disc fixedly connected to the surface of the movable column, a tension spring fixedly connected to the surface of the disc, and the tension spring fixedly connected to the support frame.

[0006] As a preferred embodiment of this invention, a pull rod is fixedly connected to the surface of the disc, and a small ball is fixedly connected to the surface of the pull rod. Both the pull rod and the small ball are made of plastic.

[0007] As a preferred embodiment of this utility model, a fixed frame is fixedly connected to the surface of the support frame, a round tube is fixedly connected to the surface of the fixed frame, a threaded rod is threadedly connected to the inside of the round tube, and the threaded rod is movably connected to the pull rod.

[0008] As a preferred embodiment of this utility model, a rotating handle is fixedly connected to the surface of the threaded rod, and the surface of the rotating handle is provided with anti-slip texture, and the number of anti-slip textures is several; the surface of the tension spring is sprayed with anti-rust paint; and a lever is fixedly connected to the surface of the protective cover, and the number of levers is several.

[0009] As a preferred embodiment of this invention, the surface of the movable column is provided with rounded corners.

[0010] As a preferred embodiment of the present invention, the back of both the first busbar trunking body and the second busbar trunking body are fixedly connected to a mounting bracket, and the surface of the mounting bracket is provided with a mounting opening, the number of which is several.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model employs an operator sliding a protective cover, which covers the outside of the busbar connector. When the limiting strip contacts the movable column, the limiting strip can push the movable column. Then, under the action of the tension spring, the movable column resets, thereby limiting the limiting strip and achieving self-locking of the protective cover. Then, the operator rotates the threaded rod, making the threaded rod fit tightly against the pull rod, thereby locking the pull rod and indirectly locking the disc and the movable column, preventing the protective cover from resetting, and thus completing the docking of the first busbar trunking body and the second busbar trunking body. This device has the advantage of facilitating docking.

[0022] As a technical optimization of this utility model, by setting up the lever and the ball 10, the operator can hold the ball 10 and then pull the lever 9, thereby pulling the disc 8.

[0023] refer to Figures 1 to 3 The support frame 5 is fixedly connected to a fixed frame 11, and the fixed frame 11 is fixedly connected to a round tube 12. The round tube 12 is internally threaded with a threaded rod 13, and the threaded rod 13 is movably connected to the pull rod 9.

[0024] As a technical optimization of this utility model, by setting up the fixing frame 11, the round tube 12 and the threaded rod 13, the operator can rotate the threaded rod 13 until the threaded rod 13 is in close contact with the round tube 12, thereby locking the position of the round tube 12.

[0025] refer to Figures 1 to 3 A rotating handle 14 is fixedly connected to the surface of the threaded rod 13. The surface of the rotating handle 14 is provided with anti-slip texture, and there are several anti-slip textures. The surface of the tension spring 7 is sprayed with anti-rust paint.

[0026] As a technical optimization of this utility model, the setting of the handle 14 allows the operator to easily rotate the threaded rod 13 by utilizing the principle of a force-saving lever. By spraying anti-rust paint on the surface of the tension spring 7, the tension spring 7 can be protected.

[0027] refer to Figures 1 to 3 The surface of the movable column 6 is rounded.

[0028] As a technical optimization of this utility model, by setting the rounded corners on the surface of the movable column 6, it is easier for the limiting strip 4 to push the movable column 6 to move.

[0031] The working principle and usage process of this utility model are as follows: In use, the operator aligns the first busbar trunking body 1 with the second busbar trunking body 2, and then uses a busbar connector to connect the conductive copper plates on the surface of the first busbar trunking body 1 and the surface of the second busbar trunking body 2. Then, the operator slides the protective cover 3 so that the protective cover 3 covers the outside of the busbar connector. When the limiting strip 4 contacts the movable column 6, the limiting strip 4 can push the movable column 6. Then, under the action of the tension spring 7, the movable column 6 resets, thereby limiting the limiting strip 4 and achieving self-locking of the protective cover 3. Then, the operator rotates the threaded rod 13 so that the threaded rod 13 is in close contact with the pull rod 9, thereby locking the pull rod 9 and indirectly locking the disc 8 and the movable column 6, preventing the protective cover 3 from resetting, and thus completing the docking of the first busbar trunking body 1 and the second busbar trunking body 2.
