[0024] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0025] like Figure 1-8 As shown, a tubular busbar with good insulation protection effect in this embodiment includes a housing 1, a housing 2 2 is installed on one side of the housing 1 through a positioning mechanism 3, and the housing 1 1 and the housing 2 2 pass through and fix the busbar body 13. The positioning mechanism 3 includes an L-shaped plate 31 nailed to the side walls of the housing 1 and the housing 2, respectively fixed with a long screw 32 and a short screw 33 on the L-shaped plates 31 on both sides, and a positioning sleeve 37 is threadedly connected on the long screw 32 and the short screw 33, and an inner screw 34 is rotatably connected to the inner wall of the long screw 32 and the L-shaped plate 31, and a moving block 35 is threadedly connected to the outer surface of the inner screw 34, and an L-shaped rod 36 fixed at the upper and lower ends of the moving block 35 slides in the openings on both sides of the long screw 32, and a rod hole corresponding to the L-shaped rod 36 is provided on one side of the positioning sleeve 37, and the inner screw 34 is driven to rotate by a knob on one side of the L-shaped plate 31.
[0026] Specifically, through the positioning mechanism 3, when the busbar body 13 is assembled and has a turning part, eight L-shaped plates 31 are respectively installed on both sides of the joint of the shell 1 and the shell 2 2 to form four sets of positioning mechanisms 3 to achieve the splicing of the shell 1 and the shell 2 2; the long screw 32 and the short screw 33 are in contact with each other at the end face, and the threads of the two form a complete screw. At this time, the positioning sleeve 37 is located on the long screw 32, and then the positioning sleeve 37 is rotated to move it to the short screw 33. The positioning sleeve 37 is docked with the long screw 32 and the short screw 33 to complete the assembly, and the positioning The rod hole on one side of the sleeve 37 corresponds to the L-shaped rod 36. Then, the knob is turned to drive the inner screw 34 inside the long screw 32 to rotate, and the moving block 35 is displaced and drives the L-shaped rod 36 to move at the opening until the L-shaped rod 36 is inserted into the rod hole of the positioning sleeve 37. At this time, the positioning sleeve 37 cannot rotate, so as to avoid the rotation of the positioning sleeve 37 due to external factors affecting the connection stability. In this way, the splicing operation between the bridge frame shells is realized, and the splicing is firm and reliable, which is convenient for the long-term use of the busbar body 13. After the splicing is completed, the busbar body 13 is passed through the shell 1 and the shell 2 2 and fixed.
[0027] like Figure 1-3 As shown, both openings of the housing 1 and the housing 2 are bonded with sealing gaskets 4, and the sealing gaskets 4 are made of anti-corrosion rubber. The housing 1 and the housing 2 are nailed with two clamping plates 5 at the other ends of the housing 1 and the housing 2, and the clamping plates 5 are provided with arc-shaped clamping holes, and the arc-shaped clamping holes are in contact with the outer wall of the busbar body 13 and fixed thereto; the housing 1 and the housing 2 are provided with openings, and the housing 1 and the housing 2 are welded with docking plates 7 on the inner side of the openings, and the docking plates 7 are connected to the sealing plates 6 with bolts, and the sealing plates 6 are used to The openings on the shell 1 and the shell 2 are closed, and the sealing plate 6 is flush with the surfaces of the shell 1 and the shell 2; the appearance of the shell 1 is a straight pipe bridge design, and the appearance of the shell 2 is a bent pipe bridge design, and the shell 1 and the shell 2 are installed with clamp rings 12 inside. The three clamp rings 12 inside the shell 1 are located between each row of the heat dissipation ports 2 11, and the two clamp rings 12 inside the shell 2 are respectively located at the horizontal and vertical ends, and the busbar body 13 passes through the clamp ring 12 and is fixed by bolts.
[0028] Specifically, in the optimized structural design of the shell 1 and the shell 2, the shell 1 and the shell 2 are designed as straight pipes and curved pipes, which facilitates the docking of the busbar body 13 extending from the ground to the turning part of the wall. After the busbar body 13 passes through the shell 1 and the shell 2, it can be assembled through the internal spliced clamp ring 12, and the clamp ring 12 is a prior art structure. After the assembly is completed, the sealing plate 6 can be connected by the docking plate 7 to seal to prevent water from entering the interior, and the sealing gasket 4 enhances the sealing of the splicing, further improving the dustproof and waterproof effect. Finally, after the terminal joint part of the busbar body 13 passes through the openings of the shell 1 and the shell 2, two clamping plates 5 can be nailed at the port of the shell 2 to effectively limit and seal the joint of the busbar body 13, thereby making the position of the joint of the busbar body 13 stable. The shell 1 and the shell 2 2 have a reasonable structural design to make the bus body 13 firm and stable, and effectively improve the insulation protection effect of the shell 1 and the shell 2 2. In this case, the positioning plate 5 is installed at the port of the shell 1 and the shell 2 2 only for the convenience of display. In actual applications, according to needs, such as installation environment and length of the bus body 13, multiple combination structures of the shell 1 and the shell 2 2 can be installed through the positioning mechanism 3.
[0029] like Figure 1-5 As shown, both sides of the shell 1 are nailed to the support base 8, and a support plate 9 is fixed on the inner side of the support base 8. The support plate 9 is provided with multiple rows of heat dissipation ports 10. The heat dissipation ports 10 are connected to the heat dissipation ports 2 11 arranged at the bottom end of the shell 1. The heat dissipation ports 10 and 11 are both inclined, and the inclination directions of the heat dissipation ports 10 and 11 are opposite.
[0030] Specifically, in terms of heat dissipation design, since the housing 1 is connected to a supporting surface, such as the ground, the bolt holes provided on the support base 8 can be fixed to the ground, and at this time, the support plate 9 fits with the bottom surface of the housing 1, and the heat dissipation port 1 10 and the heat dissipation port 2 11 of the two are connected to form a complete heat dissipation channel. At the same time, the heat dissipation port 1 10 and the heat dissipation port 2 11 are designed with two opposite inclinations, so that the heat dissipation channel is in a “>” shape, which can effectively prevent rainwater or dust from entering the interior of the shell, and then effectively prevent water and dust while dissipating heat. For the support plate 9 and the housing 1 installed on one side of the wall, the inclination direction of the heat dissipation port 1 10 and the heat dissipation port 2 11 can be the same and connected, and they can be inclined in the up and down direction, that is, the heat dissipation port 1 10 and the heat dissipation port 2 11 are inclined downward relative to the wall, so that dust falling on the heat dissipation port 1 10 and the heat dissipation port 2 11 will automatically slide down. This is an existing reasonable design method, so it will not be repeated in the figure and text.
[0031] Working principle: When assembling the busbar body 13 with a turning part, eight L-shaped plates 31 are respectively installed on both sides of the joint of the shell 1 and the shell 2, and then the shell 1 and the shell 2 are spliced, the long screw 32 and the short screw 33 are in contact at the end faces, and the threads of the two form a complete screw. At this time, the positioning sleeve 37 is located on the long screw 32, and then the L-shaped rod 36 is driven to insert into the rod hole of the positioning sleeve 37 to limit the position, and then the shell 1 is installed on the wall or the ground through the support base 8, and then the busbar body 13 passes through the shell 1 and the shell 2, and can be assembled through the internal spliced clamp ring 12, and finally after the assembly is completed, the sealing plate 6 can be covered with the docking plate 7 to seal, so as to prevent water from entering the interior, and the sealing gasket 4 can enhance the sealing of the splicing, and finally when the terminal joint part of the busbar body 13 passes through the opening of the shell 1 and the shell 2, two positioning plates 5 can be nailed at the port of the shell 2 to effectively limit and seal the joint of the busbar body 13.

The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
