Abstract

The utility model relates to a bus adjustable terminal including an adjusting barrel, and a first screw and a second screw which are mounted on two ends of the adjusting barrel. Two ends of an internal hole of the adjusting barrel are provided with internal threads in opposite rotational direction. External threads cooperatively connected with the internal threads in the adjusting barrel are disposed on the first screw and the second screw. The first screw is connected to a bus through an insulating plate. The second screw is directly or indirectly fixed onto a wall or a steel girder. When the adjusting barrel rotates in one direction, the two screws in the adjusting barrel move to the center, so that the bus is tensioned; when the adjusting barrel rotates in the opposite directions, the two screws in the adjusting barrel move outward respectively so that the bus is loosened. The bus adjustable terminal is simple in structure and is used for power bus adjustment for industrial and mining companies. The bus adjustable terminal is convenient to install and easy to adjust.

Description

A kind of bus adjustable terminal
Technical field
The utility model relates to a kind of bus adjustable terminal, belongs to industrial and mining enterprises for electrokinetics field, particularly factory floor electric power system.
Background technology
In the confession electric propulsion system of industrial and mining enterprises, the normal bus that adopts is as power power-line.So-called bus is the banded section bar that aluminium alloy or copper are done, and because its sectional area is large, resistance is little, thereby droop loss is little during work, and easy for installation, good looking appearance and obtain extensive use.The general insulator that adopts is fixed on body of wall or girder steel, and the two ends of bus are fixed.Due to the variation of ambient temperature and expanding with heat and contract with cold of metal material, when ambient temperature is high, bus extends owing to self expanding, and makes it sagging; When ambient temperature is low, due to metal contracts, by the two ends insulator, draw bad.So need regularly to adjust the two ends of bus, but, due to current structure and mounting means, it is very inconvenient to adjust.
Summary of the invention
Goal of the invention of the present utility model is to overcome the above-mentioned deficiency of prior art and a kind of bus adjustable terminal of regulating for industrial and mining enterprises power bus degrees of tightness is provided.
For achieving the above object, the technical solution of the utility model is: comprise adjustment barrel, be loaded on the first screw rod, second screw rod at adjustment barrel two ends; Described adjustment barrel endoporus two ends are provided with the internal thread that rotation direction is contrary; Described the first screw rod, the second screw rod are provided with the external screw thread be connected with the adjustment barrel screw-internal thread fit; Described the first screw rod is connected with bus through insulation board; Described the second screw rod directly or indirectly is fixed in wall or girder steel.
Described insulation board is plastic plate, resin plate or epoxy plate.
Described insulation board is rectangle, and thickness is 10-30mm.
Described adjustment barrel profile is prism-shaped.
The utility model is simple in structure, for the degree of tightness of industrial and mining enterprises' power bus, regulates, easy for installation, is convenient to adjust.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Embodiment
In Fig. 1, insulation board 1 is used for fixing bus.Bus is fixed by bolts on insulation board 1, one end of the first screw rod 2 also is fixed on insulation board 1, the other end of the first screw rod 2 is connected with adjustment barrel 3 by screw thread, and an end of the second screw rod 4 is connected with adjustment barrel 3 by screw thread, and the other end directly or indirectly is fixed on wall or girder steel.The inner two ends of adjustment barrel 3 are respectively positive and negative screw thread, and match in the first screw rod 2 and the second screw rod 4.Regular hexagon or other shapes are processed in the middle part of adjustment barrel 3, to facilitate tool using, make its rotation, and adjustment barrel 3 is rotated the first screw rod 2 and the second screw rod 4 inwardly shrinks to a direction, by insulation board 1, pulls bus to make its tensioning; Rotate round about the first screw rod 2 and the second screw rod 4 and outwards extend, thereby the bus state is relaxed.In the process that the utility model is implemented, the diameter of the first screw rod 2 and the second screw rod 4, the intensity that pitch can be as required, the degree of adjusting are determined, with adjustment barrel 3, match and get final product.The material of insulation board 1 can be plastics,, bakelite, resin plate, epoxy plate etc., its shape is generally rectangle, other shapes do not affect its realization yet, thickness is generally 10 ~ 30mm.
