Abstract

The utility model relates to a square neck bolt assembly. The square neck bolt assembly comprises a square neck bolt assembly body, a support and a capacitor, wherein a lifting piece is welded on the shell of the capacitor and fixed on the support through the square neck bolt assembly body; and the square neck bolt assembly body comprises a step bolt, a flat washer, a spring washer and a nut. The square neck bolt assembly has a simple structure, is convenient to operate, and solves the technical problem that a traditional hexagonal head bolt assembly is inconvenient to operate and has low mounting efficiency and poor fastening effect in fastening process.

Description

A kind of square neck bolt combination

Technical field

The utility model relates to the square neck bolt combination of fixed capacitor, particularly a kind ofly is used for square neck bolt combination fastening, the location high-voltage power capacitor.

Background technology

The capacitor separate unit is of paramount importance parts in the high-voltage power capacitor device, and it generally is to be installed on the metal stand, and is fastened on the metal stand by securing member.At present, existing capacitor separate unit fixed form uses common hexagon-headed bolt to be connected mostly, supporting in the combination have 1 nut, 1 spring washer and 2 plain washers, this kind connected mode is simple, but when actual installation, the requirement of engineering bolt head is positioned at rack material inside, can be very difficult when spanner stretches into, caused unhandy incident to take place, and then caused fastening poor effect, influenced the serviceability of high-voltage power capacitor, and occurring bolt in the time of fastening bolt easily rotates, the phenomenon of skidding (seeing the common hexagon-headed bolt of accompanying

drawing

4,5 representatives) has increased work difficulty, influenced operating efficiency and fastening effect, reduced fixing, stability when transportation and carrying power capacitor.

The utility model content

The purpose of this utility model is to provide a kind of square neck bolt combination, and the operation inconvenience, the installation effectiveness that occur in traditional hexagon-headed bolt combination fastening means are low to solve, the technical problem of fastening poor effect.

A kind of square neck bolt combination comprises square neck bolt combination, support and capacitor, is welded with joint hinge on the capacitor casing, and joint hinge is fixed on the support by the square neck bolt combination.

Preferably, the square neck bolt combination comprises square neck bolt, packing ring and nut.

Preferably, the square neck bolt combination comprises 1 half-round head square neck bolt, 1 plain washer, 1 spring washer and 1 nut.

Compared with prior art, there is following technique effect in the utility model:

The utility model adopts half-round head square neck bolt, its square neck structure plays and stops the bolt rotary action, and the plane of the cup head of button-headed bolt and rack inner wall have bigger contact area, add that button-headed bolt withstands shocks, the ability of vibration or alternate load is stronger, (see Fig. 5,31 represent joint hinge in the location easily, 21 represent half-round head square neck bolt), it is fastening effective, easy for installation that the not phenomenon that can occur skidding, so this square neck bolt combining structure makes that capacitor has; Because the size of joint hinge is bigger, be enough to hold spanner portion's work within it again, made things convenient for stretching into of spanner, be convenient to install and fastening operation, increase fastening effect, improved installation effectiveness, and then the stability when having improved fixing, transportation and carrying power capacitor.

Embodiment

Below in conjunction with accompanying drawing, the utility model is done further detailed narration.

Please refer to Fig. 1 and Fig. 2, the utility model provides a kind of square neck bolt combination, it comprises square neck bolt combination 2, support 1 and capacitor 3, be welded with joint hinge 31 on capacitor 3 housings, and joint hinge 31 is fixed on the support 1 by square neck bolt combination 2, and square neck bolt combination 2 comprises square neck bolt, packing ring and nut 24.

In the present embodiment, square neck bolt combination 2 comprises 22,1 spring washer 23 of 21,1 plain washer of 1 half-round head square neck bolt and 1 nut 24.Joint hinge 31 and capacitor 3 are fixed together by the mode of welding, capacitor 3 are fixed on the support 1, are joint hinge 31 is fixed on the support 1.Joint hinge 31 is finished by square neck bolt combination 2 with fixedlying connected of support 1: half-round head square neck bolt 21 passes support 1, joint hinge 31 successively, then plain washer 23 and spring washer 24 are enclosed within on the half-round head square neck bolt 21, with spanner 4 nut 24 is fastened on the half-round head square neck bolt 21 at last, with reference to figure 3, Fig. 3 is fixed on stereogram on the support 1 for square neck bolt combination 2 with capacitor 3.In the present embodiment, the effect of plain washer 22 is to increase contact area, dispersive pressure, prevent that square neck bolt from being damaged by pressure support 1 surface, the effect of spring washer 23 is after the fastening nut 24, and spring washer 23 is given 24 1 elastic force of nut, push against nut 24, make its difficult drop-off.

More than disclosed only be the application's a specific embodiment, but the application is not limited thereto, any those skilled in the art can think variation, all should drop in the application's the protection range.
