Problems solved by technology

Among the two methods, although the second method can realize the clamping of the busbar on the fixing fitting, it is relatively troublesome to adjust the length direction of the busbar during use, and the busbar and the fixing fitting may not be completely in contact. It is easy to discharge during the electrification process, and it is easy to cause galvanic corrosion
The first method also has the problem that the busbar and the fixing hardware

Embodiment Construction

[0020] The embodiment of the pipe busbar fixing hardware of the present invention: as Figure 1 to Figure 3 As shown, the pipe bus bar fixing structure includes a pipe bus bar 1 and a fixing fitting 2 sleeved on the outer periphery of the pipe bus bar 1, and the fixing fitting 2 includes a buckle plate 3, a clamping seat 4 and a bottom plate 5 distributed sequentially from top to bottom, wherein the buckle The plate 3 is a semi-circular plate body, the concave part of the pinch plate 3 forms an upper concave surface buckled on the half of the outer peripheral surface of the pipe busbar 1, and the two ends of the pinch plate 3 are fixedly connected to the socket 4 by connecting screws 6. Above, the upper end of the card holder 4 is provided with a lower concave surface that is sunken downward, and the upper and lower concave surfaces are both semi-cylindrical, and the card holder 4 and the buckle plate 3 are surrounded by a positioning hole extending forward and backward connect...

Abstract

The invention discloses a tubular bus-bar fixing fitting. According to the tubular bus-bar fixing fitting, adjusting rollers are assembled on the wall of a locating hole, wherein each adjusting roller rotates around the axis extending in the direction of the tangent to periphery. Each adjusting roller is provided with a contact portion which is located in the locating hole and in contact with the peripheral surface of a tubular bas-bar. When the tubular bus-bar fixing fitting is used, the adjusting rollers can guide the tubular bus-bar to move in the axial direction of the locating hole through rotation of the adjusting rollers, and therefore the effects that the tubular bus-bar is loosened or fixed and it is guaranteed that the tubular bus-bar can be flexibly adjusted are achieved. In addition, due to the fact that during adjustment, the adjusting rollers cannot influence length adjustment of the tubular bus-bar, the problem that in the prior art, a fixing fitting for loosening and fixing influences the movement adjustment of the tubular bus-bar severely is avoided, the adjustment range of the tubular bus-bar is expanded, and the flexibility of adjustment of the tubular bus-bar is improved.

Description

technical field [0001] The invention relates to the technical field of pipe busbar fittings, in particular to a pipe busbar fixing fitting. Background technique [0002] At present, the pipe busbar fixing fittings are used to fix the pipe busbar on the post insulator or on the post insulator with a clamp. The fixing fittings should meet the requirements of the pipe busbar being tightly fixed or loosely fixed (slidable) in the fixing fittings. Require. [0003] There are mainly two ways to realize the installation requirements of tight or loose fixing of the pipe bus bar in the existing pipe bus fixing fittings. The first method is to realize the installation requirement of loose fixing through the sliding of the fixing fittings, which is similar to the announcement number CN200953450Y The fixed fittings in the pipe-busbar connection combination fittings disclosed in the Chinese invention patent, this kind of fixing fittings include a base, a clamp and a buckle plate arrange...
