Description

Technical Field

[0001] The utility model relates to the technical field of bus ducts, and in particular to an installation structure of a intensive bus duct. Background Art

[0002] Bus duct is a closed metal device composed of copper and aluminum busbar columns. It is used to distribute large power to various components of the distributed system. It has increasingly replaced wires and cables in indoor low-voltage power transmission trunk projects. Dense bus duct is a type of bus duct. Among them, dense bus duct is usually a multi-section structure. Multiple dense bus ducts are usually fixed and connected by fixing bolts. This connection method has the following defects: First, when faced with large-scale installation needs, the installation efficiency is low; second, when the dense bus duct is damaged, the shell surface of the bus duct is prone to deformation, and the fixing bolt connection is difficult to disassemble, which increases the difficulty of later maintenance. Summary of the invention

Since the inner wall of the positioning groove is provided with two symmetrically arranged first sliding grooves, and the sliding groove is provided with a sliding rod slidably connected to the first sliding groove and a first return spring fixedly connected to the sliding rod, and the end of the sliding rod is provided with a first inclined surface, and the positioning protrusion is provided with two second inclined surfaces, and the sum of the bevel angles of the first inclined surface and the second inclined surface is 90 degrees, therefore, when the positioning protrusion When sliding into the positioning groove, the second inclined surface on the second connecting plate contacts the first inclined surface on the sliding rod, and the two sliding rods slide out of the first sliding groove to both sides. When the second connecting plate enters the position between the sliding rod and the inner wall of the positioning groove, the two sliding rods will automatically reset through the elastic force provided by the first reset spring. Since the width of the second connecting plate is adapted to the spacing between the sliding rod and the inner wall of the positioning groove, the position of the first connecting plate will be stuck between the sliding rod and the inner wall of the positioning groove, thereby ensuring the relative position of the first mounting block and the second mounting block to be stable. In this way, the two bus duct bodies can be quickly installed, greatly improving the installation efficiency.

[0006] The utility model is further configured as follows: the surfaces of the first mounting block and the second mounting block are both provided with a plurality of reinforcing ribs, and the reinforcing ribs are evenly distributed on the first mounting block and the second mounting block.

[0007] The utility model is further configured as follows: the second mounting block is provided with a connecting rod slidably connected to the second mounting block, a first connecting rod movably connected to the connecting rod and a second connecting rod movably connected to the connecting rod, the second mounting block is provided with a second sliding groove, the connecting rod is slidably connected to the second sliding groove, and the connecting rod is also provided with a second return spring, the two ends of the second return spring are respectively fixedly connected to the connecting rod and the inner wall of the second sliding groove, the first connecting rod and the second connecting rod are respectively movably connected to the sliding rod, the central axis of the second sliding groove and the central axis of the second mounting block are in the same vertical plane, and when the second return spring is in the initial state, the spacing between the two sliding rods is adapted to the length of the second connecting plate.

[0008] By adopting the above technical solution, when it is necessary to disassemble two bus duct bodies installed together, the connecting rod is pushed to slide along the second sliding groove in the direction close to the sliding rod, so that the two sliding rods move in opposite directions along the first sliding groove, so that the distance between the two sliding rods is greater than or equal to the length of the second connecting plate, and then the first connecting plate is pushed to make the second connecting plate withdraw from the positioning groove. When the disassembly work is completed, the connecting rod and the two sliding rods are automatically reset through the elastic force of the first return spring and the second return spring, which can greatly improve the efficiency of disassembling the bus duct body.

[0009] The utility model is further configured as follows: a rubber sleeve is provided on the outer surface of the sliding rod, and the inner diameter of the rubber sleeve is matched with the outer diameter of the sliding rod.

[0010] By adopting the above technical solution, since a rubber sleeve is provided on the outer surface of the sliding rod, the rubber material has good flexibility and friction, which can further improve the strength of the sliding rod and the friction between the sliding rod and the inner wall of the first sliding groove, thereby ensuring the position stability of the sliding rod and further ensuring the connection stability between the two bus duct bodies.
