Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bus ducts, in particular to a bus duct with high sealing performance. Background Art
[0002] Bus duct is a device used for power transmission. It consists of a metal shell and internal conductors. Bus duct has the advantages of compact structure, easy installation and high reliability. It is widely used in industrial, commercial and civil buildings. The shell of bus duct is usually made of materials such as aluminum alloy or stainless steel, which has good corrosion resistance and protection performance. The internal conductor is made of materials such as copper or aluminum, which has good electrical conductivity and thermal conductivity. There are many ways to install bus duct, such as hanging, supporting, embedded, etc., which can be selected according to different installation environments and requirements. In order to ensure the stability and reliability of power transmission, high sealing is usually required to effectively prevent dust, moisture and other impurities from entering the bus duct.
[0003] Existing high-sealing busbars typically utilize advanced sealing technologies and materials to ensure their tightness. The outer shells of these busbars may be constructed from high-strength metal materials, such as aluminum alloy or stainless steel, and sealed with specialized sealing structures and sealants. Furthermore, high-quality seals are used at the busbar connections to prevent power leakage and the ingress of foreign matter. These highly sealed busbars are widely used in industrial, commercial, and residential applications, effectively ensuring the stability and reliability of power transmission.
[0004] However, the existing highly sealed bus duct lacks a protective shell on the outside, which causes the terminals to be exposed when not in use. This may cause the bus duct to be corroded and damaged by the external environment, thereby affecting its performance and service life. In addition, when inserted shallowly, part of the terminals are exposed, which may increase safety risks such as electric shock and short circuit. Therefore, a highly sealed bus duct is proposed to solve the above problems. Utility Model Content

[0013] The bottom of the fixing column is fixedly connected to the top of the telescopic housing, and the outer wall of the connecting housing is fixedly connected to a rotating mechanism;
[0014] As a further description of the above technical solution:
[0015] A worm is rotatably connected inside the rotating mechanism, and a knob is fixedly connected to the outer wall of the worm;

The outer wall of the sliding column 15 is sleeved with a spring 16, and one end of the spring 16 is fixedly connected to the card block 13. The outer wall of the card block 13 is slidably connected to the inside of the card slot 14, and one end of the outer wall of the spring 16 is fixedly connected to the outer wall of the fixed shell 1. The protective door 7 is provided with a sealing component, which acts to seal the telescopic shell 2.
[0033] Specifically, pull the fixed disc 12, and the sliding column 15 is driven to move through the fixed disc 12, and then the block 13 is driven to move through the sliding column 15, and the spring 16 is compressed at the same time, and then the rotating tooth 4 can be rotated, and the fixedly connected rotating column 9 is driven to rotate through the rotating tooth 4, and then the limiting groove 10 is driven to rotate through the rotating column 9, and then the moving column 11 is driven to move through the limiting groove 10, thereby driving the telescopic shell 2 to move, so as to close and protect the bus duct 5 or open the connection. At the same time, the telescopic length of the telescopic shell 2 can be adjusted according to the insertion depth to prevent all exposure from causing pollution and damage, thereby providing additional protection and reducing the impact of the external environment on the bus duct 5, such as dust, moisture, corrosion, etc., and it is convenient to open the protective shell when in use, which is convenient for the insertion and connection of the bus duct 5, enhancing safety and reducing safety risks such as electric shock and short circuit.
[0034] Reference Figure 1 The sealing component includes a rubber plug 6, and the outer wall of the rubber plug 6 is fixedly connected to the outer wall of the protective door 7.
[0035] Specifically, when the protective device is closed through the protective door 7, the rubber plug 6 can improve the airtightness of the device, reduce the possibility of dust, moisture, etc. entering, and enhance the protective effect, further reducing the impact of the external environment on the bus duct 5.
[0036] Reference Figure 1 and Figure 4 The outer wall of the telescopic shell 2 is fixedly connected to the connecting shell 19, the inner wall of the connecting shell 19 is fixedly connected to the fixing column 20, the bottom of the fixing column 20 is fixedly connected to the top of the telescopic shell 2, the outer wall of the connecting shell 19 is fixedly connected to the rotating mechanism 3, the rotating mechanism 3 is rotatably connected to the worm 17, the outer wall of the worm 17 is fixedly connected to the knob 24, the rotating mechanism 3 is rotatably connected to the turbine 18, the turbine 18 is meshed with the worm 17, the outer wall of the turbine 18 is fixedly connected to the transmission rod 23, the outer walls of the transmission rod 23 are rotatably connected to the rotating rod 22, the outer wall of the rotating rod 22 is rotatably connected to the clamp 21, and the clamp 21 is slidably connected to the outer wall of the fixed column 20.
[0037] Specifically, the knob 24 is turned to drive the worm 17 to rotate, and the engagement between the worm 17 and the turbine 18 is utilized to ensure the transmission of large torque and moment, thereby driving the transmission rod 23 to rotate through the turbine 18, and then driving the rotating rod 22 connected to the rotation to rotate through the transmission rod 23, and then driving the clamp 21 to rise and fall through the rotating rod 22, so as to clamp the connection stably, which can effectively disperse the pressure on the connection part and reduce the deformation and damage of the bus duct 5.

The connected fixed shell 1 slides inside and, after reaching the appropriate position, releases the fixed disc 12, and the spring 16 rebounds to drive the fixed connected block 13 to slide into the slot 14 to clamp it, thereby connecting the bus duct 5.
