[0026] See also Figure 1-4 A plug-in box assembly for a bus duct includes a base plate 1 and an outer frame 2. A junction box 101 and a wiring box 102 are arranged on the top of the base plate 1. Fixed blocks 4 are fixedly installed at both ends of the left and right sides of the base plate 1. An assembly mechanism 5 is arranged between the four fixed blocks 4 and the outer frame 2.
[0027] In this embodiment, the assembly mechanism 5 includes a accommodating chamber 501 opened inside the fixed block 4, a pressure rod 502 is installed inside the accommodating chamber 501, a pressure block 503 slidably connected to the inner wall of the accommodating chamber 501 is fixedly installed on the outer surface of the pressure rod 502, a spring 1 504 is fixedly installed between the pressure block 503 and the two ends of the inner bottom wall of the accommodating chamber 501, an accommodating chamber 2 505 located on the lower side of the accommodating chamber 1 501 is opened inside the fixed block 4, a slider 506 is slidably installed inside the accommodating chamber 2 505, a spring 2 507 is fixedly installed between the slider 506 and the inner wall of the accommodating chamber 2 505, and an insertion rod 508 is fixedly installed on one side of the slider 506.
[0028] In this embodiment, docking grooves 3 are provided at the four corners on the top of the bottom plate 1 , docking blocks 6 are fixedly installed at the four corners on the bottom of the outer frame 2 , and the four docking grooves 3 are adapted to the docking blocks 6 .
[0029] It should be noted that, with the cooperation of the docking grooves 3 and the docking blocks 6, during installation, the four docking blocks 6 can be inserted into the docking grooves 3 to perform preliminary positioning of the assembly between the base plate 1 and the outer frame 2, facilitating subsequent assembly operations.
[0030] A flip cover is rotatably mounted on the top of the fixed block 4, and a pull ring is fixedly mounted on the top of the flip cover.
[0031] It should be noted that, by providing a flip cover, the pressure rod 502 can be easily protected inside the flip cover to avoid accidental contact and triggering of the assembly mechanism 5, thereby making the installation stable and safe and improving the reliability during assembly.
[0032] In this embodiment, a bevel groove is provided on the top of the slider 506 , and the bottom of the pressure rod 502 is a slope, the bevel groove and the slope are matched, and a socket is provided on one side of the four docking blocks 6 , and the four sockets are matched with the insertion rod 508 .
[0033] It should be noted that, through the cooperation of the pressure rod 502 and the inclined surface, when the pressure rod 502 is pressed downward, the slider 506 can be driven to move, and the elastic force of spring 1 504 and spring 2 507 can be used to make the insertion rod 508 quickly inserted into or withdrawn from the inside of the socket, thereby realizing the assembly and disassembly between the base plate 1 and the outer frame 2. During maintenance, the outer frame 2 is disassembled, and the base plate 1 and the junction box 101 and the wiring box 102 on its top are all exposed to the outside, which provides a larger maintenance space than the traditional box door that only opens one side.
[0034] In this embodiment, sealing strips are fixedly installed at the four edges of the top of the bottom plate 1, and sealing grooves are opened at the four edges of the bottom of the outer frame 2, and the four sealing grooves are adapted to the sealing strips.
[0035] Specifically, sealing strips are fixedly installed at the four edges of the top of the bottom plate 1. The function of these sealing strips is to provide dust and water protection and to prevent other external particles or liquids from entering the inside of the plug-in box when the bottom plate 1 is combined with the outer frame 2. Sealing grooves are opened at the four edges of the bottom of the outer frame 2. These sealing grooves are specially designed to receive the sealing strips on the bottom plate. When the bottom plate 1 and the outer frame 2 are assembled together, a closed shell is formed to protect components such as the junction box 101 and the wiring box 102 in the closed box body, and the sealing strips are inserted into the sealing grooves to enhance the sealing effect.
[0036] It should be noted that after the above scheme is adopted in this scheme, the structures and installation methods not described in the description can adopt conventional structures on the market.
[0037] Working principle: When maintaining the plug-in box, first open the flip cover and press the pressure rod 502 downward. The pressure rod 502 drives the pressure block 503 to move downward, squeezing the spring 1 504. The inclined surface at the bottom of the pressure rod 502 is inserted into the inclined groove at the top of the slider 506, thereby driving the slider 506 to move in the direction of the spring 2 507 inside the accommodating chamber 2 505, squeezing the spring 2 507, and the slider 506 drives the insertion rod 508 to move in the direction of the slider 506, so that the insertion rod 508 withdraws from the inside of the socket. At this time, the outer frame 2 is removed, and the docking block 6 withdraws from the inside of the docking groove 3. Then the bottom plate 1 is separated from the outer frame 2, and then maintenance work is carried out.
[0038] The beneficial effects of the above embodiments are:
[0039] The plug-in box assembly for the bus duct is provided with an assembly mechanism 5 so that the bottom plate 1 and the outer frame 2 can be disassembled and separated. After the outer frame 2 is disassembled, the internal components of the plug-in box such as the junction box 101 and the wiring box 102 are exposed to the outside in a large area, thereby facilitating maintenance work.
[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
