Description

Technical Field

[0001] The utility model belongs to the technical field of bus ducts, and in particular relates to an adjustable earthquake-resistant bus duct. Background Art

[0002] With the emergence of modern engineering facilities and equipment, electricity consumption in all walks of life has increased rapidly, especially with the emergence of numerous high-rise buildings and large factories. Traditional cables as transmission conductors can no longer meet the requirements in today's high-current transmission systems. The parallel use of multiple cables has brought many inconveniences to on-site installation and construction connections. Bus ducts have increasingly replaced wires and cables in indoor low-voltage power transmission trunk line projects.

[0003] The existing bus duct structure is relatively simple, and most of the bus ducts do not have a shockproof function. During use, the copper busbars may sometimes be damaged due to vibration, which will have an adverse effect on the use of the bus duct. For this reason, we propose an adjustable earthquake-resistant bus duct. Utility Model Content

[0004] The utility model aims to provide an adjustable earthquake-resistant bus duct to solve the problem in the above-mentioned background technology that the existing bus duct has a single structure and does not have an earthquake-proof function.

[0006] Preferably, a groove body is fixedly provided on the inner side of the metal shell, and a shock absorbing plate is slidably connected to the upper and lower sides of the groove body, and a limiting groove plate is fixedly installed on the bottom of the shock absorbing plate.

[0007] Preferably, a connecting block is fixedly installed on the top of the shock-absorbing plate, a buffer rod is fixedly connected to the top of the connecting block, and a support rod is sleeved and connected to the top of the buffer rod.

[0008] Preferably, a threaded rod is rotatably connected to the top end of the support rod, the threaded rod is threadably connected to the surface of the metal shell, and a turntable is fixedly mounted on the top end of the threaded rod.

[0009] Preferably, a buffer cavity is fixedly opened on the inner side of the support rod, and a damping block is fixedly installed on the inner top of the buffer cavity.

[0010] Preferably, a spring is fixedly connected to the bottom of the damping block, a pressure block is fixedly installed on the top of the buffer rod, and the top of the pressure block is fixedly connected to the bottom end of the spring.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The rotation of the threaded rod can drive the support rod and the buffer rod to move vertically. The movement of the support rod and the buffer rod can adjust the distance between the limit slot plates, thereby improving the use effect of the device. When the device vibrates during use, the vibration-absorbing plate can preliminarily absorb the vibration generated on the surface of the insulated copper busbar of the wire. When the force of vibration drives the buffer rod and the pressure block to compress the spring inside the buffer cavity, the force generated by the spring can be absorbed by the damping block, thereby improving the shockproof effect of the device.
