Description

Technical Field

[0001] The utility model belongs to the technical field of bus ducts, and particularly relates to a bus duct sealing structure. Background Art

[0002] Bus duct is a closed metal device composed of copper and aluminum busbars, which is used to distribute high power to various components of the distributed system. With the emergence of modern engineering facilities and equipment, traditional cables as transmission conductors can no longer meet the requirements in high-current transmission systems. The parallel use of multiple cables has brought many inconveniences to on-site installation and construction connections. Plug-in bus duct has emerged as a new type of distribution conductor. Compared with traditional cables, it fully demonstrates its superiority in high-current transmission.

[0003] According to a bus duct sealing structure disclosed in the patent publication number CN219371967U, the utility model is stabilized by providing a slider inside the first box body and a slide groove inside the second box body, so that the installation can be operated independently, the bolts on the top of the first box body drive the clamping strips on both sides of the first box body to move, and the clamping strips drive the clamping blocks to move downward at the same time, and the clamping slots on both sides of the top of the second box body are installed in the grooves, and the clamping blocks move downward and are clamped in the clamping slots to fix them. This sealing structure is conducive to the later disassembly and maintenance of the bus duct, but there are still the following shortcomings, such as:

[0004] When sealing the bus duct, the device still needs to turn the bolts to fix it. This is inconvenient during installation and disassembly, and it still takes time in the later inspection process, affecting work efficiency. Therefore, we propose a bus duct sealing structure. Utility Model Content

[0005] The utility model aims to provide a bus duct sealing structure, which can quickly complete the installation work by setting a fixing component, reduce the labor of the staff, improve the work efficiency, and solve the problem that the existing bus duct sealing still needs to rotate the bolts for fixing, which is inconvenient in installation and disassembly operations.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model discloses a bus duct sealing structure, comprising a bus duct, a cover plate is arranged on the top of the bus duct, a fixing assembly is arranged on the front of the bus duct, a disassembly assembly is arranged on the right side of the fixing assembly, the fixing assembly comprises a fixing block 1, and a connecting block is arranged on the left side of the fixing block 1;

[0008] The fixing block is provided with an installation block inside, a clamping block is provided inside the installation block, a threaded rod is rotatably connected inside the connecting block, a turning handle is provided on the left side of the connecting block, and a limiting rod is fixedly connected to the right side of the connecting block. The limiting rod is provided to limit the installation block, and when not in use, it can avoid the situation where the installation block is rotated by accidentally touching the turning handle, which would cause the limit block to shift.

[0009] Furthermore, a stabilizing block 1 is fixedly connected to the inner wall of the card block, a stabilizing block 2 is arranged on the outer side of the stabilizing block 1, a spring 1 is arranged inside the stabilizing block 2, and the stabilizing block 1 is slidably connected to the stabilizing block 2. The stabilizing block 1 and the stabilizing block 2 are arranged to improve the stability of the card block during movement and facilitate the storage of the spring 1.

[0014] Furthermore, the right side of the mounting block is plugged into a fixed block, the limit block is slidably connected to a fixed block, the top of the spring is fixedly connected to the top of the inner wall of the stabilizing block, and the bottom of the spring is fixedly connected to the bottom of the inner wall of the stabilizing block. By setting the mounting block for plugging with the fixed block, the cover plate is fixed by the action of the clamping block.
