Description

A kind of electric power fastening piece
[technical field]
The utility model relates to the technical field of threaded fastener, particularly the technical field of electric power fastening piece.
[background technique]
Controller switching equipment is the guarantee being related to residential electricity consumption; controller switching equipment can use the fastening pieces such as bolt to install usually; in current power transmission and transforming equipment work running, the converting equipment bolt looseness caused due to reasons such as construction process, equipment resonance and cause equipment heating even to burn causing the phenomenon had a power failure to happen occasionally completely.And clamping bolt also exists serious heating problem under the effect of leakage field, the heating of clamping bolt directly affects the stability of the normal operation of distribution box and then affects electric power facility reliability of operation.
In addition, because controller switching equipment only uses bolt to be fixed, cause some equipment seriously stolen, controller switching equipment is as the upper level power supply being directly customer power supply, and equipment is stolen not only can bring larger economic loss, also can have a strong impact on reliable power supply.
[model utility content]
The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of electric power fastening piece, and structure is simple, power equipment is installed firmly, has antitheft effect, avoid the fever phenomenon that magnetic induction causes too greatly.
For achieving the above object, the utility model proposes a kind of electric power fastening piece, comprise bolt, pad and nut, described bolt is integrally formed by connecting by bolt head, flanged surface, bolt shank, and bolt shank is provided with screw thread, and the end of bolt shank is provided with chamfering section; Described pad is sleeved on bolt shank, and pad is anti-magnetic insert; Described nut sleeve is contained on bolt shank, and the internal thread of nut coordinates with the outside thread of bolt shank to be installed; Described bolt head is outer Octagonal plum-blossom head, and nut is cylindrical, and the outer wall of nut has bar-shaped trough, and the installation and removal of nut need to use special tool.
As preferably, described flanged surface is provided with rib tooth near the end face of bolt shank, and rib tooth even circumferential distributes.
As preferably, described bar-shaped trough is the groove longitudinally arranged, and the quantity of bar-shaped trough is three, and bar-shaped trough is circumferentially spaced apart.
As preferably, described pad is anti-magnetic insert, and pad can use copper sheet, aluminium flake, Cuprum alloy or stainless steel.
The beneficial effects of the utility model: the utility model structure is simple, power equipment is made to install firmly, rib tooth can make assembling more firm, play locking effect, general spanner cannot rotating bolt head and nut, and handling need to use special tool, have antitheft effect, the fever phenomenon that the pad with antimagnetic effect can avoid magnetic induction to cause too greatly, ensures the stability that distribution box normally runs.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.
[accompanying drawing explanation]
Fig. 1 is the plan view of a kind of electric power fastening piece of the utility model;
Fig. 2 is the schematic perspective view of a kind of electric power fastening piece of the utility model;
Fig. 3 is the right elevation of a kind of electric power fastening piece of the utility model.
In figure: 1-bolt, 11-bolt head, 12-flanged surface, 13-bolt shank, 14-chamfering section, 15-rib tooth, 2-pad, 3-nut, 31-bar-shaped trough.
[embodiment]
Consult Fig. 1, Fig. 2 and Fig. 3, the utility model, comprise bolt 1, pad 2 and nut 3, described bolt 1 is integrally formed by connecting by bolt head 11, flanged surface 12, bolt shank 13, and bolt shank 13 is provided with screw thread, and the end of bolt shank 13 is provided with chamfering section 14; Described pad 2 is sleeved on bolt shank 13, and pad 2 is anti-magnetic insert; Described nut 3 is sleeved on bolt shank 13, and the internal thread of nut 3 coordinates with the outside thread of bolt shank 13 to be installed; Described bolt head 11 is outer Octagonal plum-blossom head, and nut 3 is cylindrical, the outer wall of nut 3 has bar-shaped trough 31, and the installation and removal of nut 3 need to use special tool.Described flanged surface 12 is provided with rib tooth 15 near the end face of bolt shank 13, and rib tooth 15 even circumferential distributes.Described bar-shaped trough 31 is the groove longitudinally arranged, and the quantity of bar-shaped trough 31 is three, and bar-shaped trough 31 is circumferentially spaced apart.Described pad 2 is anti-magnetic insert, and pad 2 can use copper sheet, aluminium flake, Cuprum alloy or stainless steel.
Utility model works process:
A kind of electric power fastening piece of the utility model in the course of the work, during installation, fit on bolt 1 in mounting hole, the two ends of bolt 1 all add antimagnetic pad 2, then fastening nut 3, the rib tooth 15 on the flanged surface 12 of bolt head 11 can make assembling more firm, plays locking effect.Because bolt head 11 is outer Octagonal plum-blossom head, general spanner cannot rotating bolt 1, and nut 3 is cylindrical, outer wall is without corner angle, general spanner also cannot rotating nut 3, can only could be dismantled, reach anti-theft effect by the bar-shaped trough 31 on special instrument attaching nut 3.Pad 2 is anti-magnetic insert, and pad 2 uses copper sheet, aluminium flake, Cuprum alloy or stainless steel, the fever phenomenon that the pad 2 with antimagnetic effect can avoid magnetic induction to cause too greatly, ensures the stability that distribution box normally runs.
The utility model structure is simple, power equipment is made to install firmly, rib tooth 15 can make assembling more firm, play locking effect, general spanner cannot rotating bolt head 11 and nut 3, and handling need to use special tool, have antitheft effect, the fever phenomenon that the pad 2 with antimagnetic effect can avoid magnetic induction to cause too greatly, ensures the stability that distribution box normally runs.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, anyly all belongs to protection domain of the present utility model to the scheme after the utility model simple transformation.
