Description

Technical Field

[0001] This utility model belongs to the field of power equipment technology, and in particular relates to a locking tool for a tubular busbar conductive pipe connection device. Background Technology

[0002] The conductive tube of the tubular busbar is the core conductive component of the tubular busbar, which undertakes the key function of transmitting electrical energy. It is the main structure of the tubular busbar and is usually a hollow tubular structure made of metal material with high conductivity. It is mostly circular in shape.

[0003] The connection device for the conductive tube typically uses two semi-circular arc-shaped current-carrying conductive plates and two semi-circular arc-shaped steel plates. The inner wall of the semi-circular arc-shaped current-carrying conductive plates is tightly fitted to the outer wall of the tubular busbar, while the inner wall of the semi-circular arc-shaped steel plates is tightly fitted to the outer wall of the current-carrying conductive plates. The two semi-circular arc-shaped steel plates are then welded together and tightly hold the two semi-circular arc-shaped current-carrying conductive plates, thus tightly holding the tubular busbar conductive tube.

[0004] The locking of the two semi-circular steel plates is crucial to the connection of the tubular busbar conductive pipe. Conventional locking tools for semi-circular steel plates are cumbersome and inconvenient to operate. Therefore, we propose a locking tool for the tubular busbar conductive pipe connection device. Utility Model Content

[0005] The purpose of this invention is to provide a locking tool for a tubular busbar conductive tube connection device to solve the problems mentioned in the background art.

[0006] In view of this, the present invention provides a locking tool for a tubular busbar conductive tube connection device, comprising:

[0007] The pressure plate and the through groove are provided. The through groove is opened inside the pressure plate and is connected to the outside. The bottom surface of the pressure plate is provided with an arc-shaped groove. A conductive tube is provided below the pressure plate. Two current-passing conductive plates are provided around the conductive tube. Two steel plates are provided around the two current-passing conductive plates respectively, and one of the steel plates is in contact with the inner wall of the arc-shaped groove.

[0008] A chain, one end of which is rotatably connected to one end of a pressure plate, and the other end of which is rotatably connected to a rotating block. A threaded rod is fixedly connected to the top of the rotating block, and one end of the threaded rod passes through a through groove and extends to the outside. A threaded sleeve is threadedly connected to the threaded rod, and the threaded sleeve is in contact with the top surface of the pressure plate.

[0009] Based on the above structure, the through groove and threaded rod ensure that the threaded rod can be inserted into the through groove. The threaded sleeve ensures that when the user tightens the threaded sleeve with a tool, the threaded rod will be acted upon by the thread of the threaded sleeve and move upward through the through groove. The chain and rotating block ensure that the other end of the chain can rotate on the rotating block. When the threaded rod moves upward, it will pull the other end of the chain through the rotating block, causing one end of the chain to rotate on one end of the pressure plate. The conductive tube, current-carrying conductive plate, and steel plate ensure that when the chain is tightened, the chain will tightly press the outer walls of the two steel plates, causing the two steel plates to press the outer walls of the two current-carrying conductive plates respectively, thus clamping the conductive tube between the two current-carrying conductive plates and the conductive tube, forming an interference fit.

[0010] In the above technical solution, the top end of the threaded sleeve is hexagonal.

[0011] In this technical solution, it is ensured that the user can tighten the top of the threaded sleeve using a tool.

[0012] In the above technical solution, the threaded rod is further fitted with the through groove.

[0013] In this technical solution, it is ensured that the user can insert one end of the threaded rod into the through groove.

[0014] In the above technical solution, the inner wall of the arc-shaped groove is further adapted to the outer wall of one of the steel plates.

[0015] In this technical solution, it is ensured that the inner wall of the arc groove can be tightly attached to the outer wall of one of the steel plates.

[0016] In the above technical solution, furthermore, the inner walls of the two current-passing conductive plates are in close contact with the periphery of the conductive tube.

[0017] In this technical solution, it is ensured that when the outer walls of the two overcurrent conductive plates are squeezed, the inner walls of the two overcurrent conductive plates can squeeze the periphery of the conductive tube.

[0018] In the above technical solution, furthermore, the inner walls of the two steel plates are tightly attached to the outer walls of the two current-carrying conductive plates.

[0019] In this technical solution, it is ensured that when the outer walls of the two steel plates are squeezed, the inner walls of the two steel plates can squeeze the outer walls of the two current-carrying conductive plates respectively.

[0020] In the above technical solution, the chain is further described as being in close contact with the outer walls of the two steel plates.

[0021] In this technical solution, it is ensured that when the other end of the chain is pulled, the chain can effectively compress the outer walls of the two steel plates and fix the two steel plates in place.

[0022] The beneficial effects of this utility model are:

[0023] The locking tool of this tubular busbar conductive tube connection device, through a through groove and a threaded rod, ensures that the threaded rod can be inserted into the through groove. A threaded sleeve ensures that when the user tightens the sleeve, the threaded rod is acted upon by the threaded sleeve, moving upwards through the through groove. A chain and a rotating block ensure that the other end of the chain can rotate on the rotating block. When the threaded rod moves upwards, it pulls the other end of the chain through the rotating block, causing one end of the chain to rotate on one end of the pressure plate. The conductive tube, current-carrying conductive plate, and steel plate ensure that when the chain is tightened, it tightly presses against the outer walls of the two steel plates, causing the two steel plates to press against the outer walls of the two current-carrying conductive plates, clamping the conductive tube and creating an interference fit between the two current-carrying conductive plates and the conductive tube. This solves the problem of conventional semi-circular steel plate locking tools being bulky and inconvenient to operate. Attached Figure Description
