Abstract

The utility model discloses a combined bolt and relates to a component of an automobile. The combined bolt comprises a hexagonal flange bolt (1). The hexagonal flange bolt (1) is equipped with a screw (2). A waveform gasket (3) is sleeved on the screw (2). The waveform gasket (3) is of an annular structure having an opening. In addition, the waveform gasket (3) is in the structure of waves along a circumferential direction. The combined bolt helps to solve a problem that a conventional combined bolt is poor in anti-loosening performance.

Description

A kind of assembling bolt

Technical field

The utility model relates to a kind of automobile and uses component.

Background technique

Automobile is used bolt at present, generally is to adopt elastic washer assembling bolt structure, and the elastic washer edge of this bolt is the lineal shape that is inclination.The anti-loosening property of this bolt is poor.In use, because automobile is in the wavy attitude in motion top, becoming flexible can appear in the therefore long-time back bolt that uses, and very easily causes security incident.

The model utility content

The utility model provides a kind of assembling bolt, and the utility model has solved the problem of the anti-loosening property of existing assembling bolt difference.

For addressing the above problem, the utility model adopts following technological scheme: a kind of assembling bolt, comprise hexagonal flange bolt 1, and screw rod 2 is arranged on the hexagonal flange bolt 1; On screw rod 2, be set with wave washer 3, wave washer 3 is loop configuration that opening is arranged, and said wave washer 3 is along circumferencial direction undulate structure.

Therefore the utility model can prevent automobile bolt looseness phenomenon in movement process because packing ring adopts wavy shaped configuration.The wave packing ring can strengthen the anti-loosing effect of assembling bolt.
