Abstract
The present invention relates to a kind of self-expanding bolt, ring flange, polished rod and the threaded rod being connected with head including head, described polished rod periphery has the axial bar groove of many groups and circular array, is embedded with self-expanding sealing strip at all described axial bar grooves.A kind of self-expanding bolt of the present invention, the expanding sealing strips being arranged on polished rod is after ingress of air, more than 5 times of own vol will be expanded through 18 hours, the gap filling being connected between polished rod with subframe, vehicle body, there is damping and water-proof function, thus reach improve bolt head intensity and improve the effect of bolt anti-fatigue life.
Description
Technical field
The present invention relates to a kind of bolt, be specifically related to a kind of self-expanding bolt, belong to technical field of fastening.
Background technology
Hexagonal flange card bolt is the fundamental parts rising in machinery and coupling fastening effect.Hexagonal flange card bolt by
Low in the ring flange and production cost with bigger supporting surface, and be widely used in crucial occasion.Owing to manufacturing, fastening
Demand, the ring flange of hexagonal flange card bolt would generally be designed with 0.25 °～the bevel angle of 1.25 ° so that
Hexagonal flange card bolt, after coupling connected compcnent, has higher sealing.
But, the connection at two or more parts that some are chronically exposed in air, do not allow for pneumatosis
Or from the point of view of the occasion of hydrops, be just not suitable for using conventional hexagonal ring flange hook bolt.Such as, for the subframe in automobile chassis
To the connection of vehicle body, if using common hexagonal flange card bolt-connection, then can there is hydrops, causing the situation of corrosion.
Therefore, it is necessary to provide the technical scheme improved to overcome above technical problem present in prior art.
Summary of the invention
It is an object of the invention to the deficiency overcoming prior art to exist, it is provided that a kind of self-expanding bolt, to solve to be joined
The problem such as pneumatosis, hydrops between fitting.
For reaching above-mentioned purpose, the technical solution used in the present invention is: a kind of self-expanding bolt, including head and head
Ring flange, polished rod and the threaded rod connected, has the axial bar groove of many groups and circular array on described polished rod periphery,
It is embedded with self-expanding sealing strip at all described axial bar grooves.
Preferably, described axial bar groove and described self-expanding sealing strip at least have 8 groups.
Preferably, described expanding sealing strips is thermoplasticity EPT rubber packing bar.
Due to the utilization of technique scheme, the present invention compared with prior art has the advantage that
A kind of self-expanding bolt of the present invention, the expanding sealing strips being arranged on polished rod was after ingress of air, through 1-8 hour
More than 5 times of own vol will be expanded, the gap filling being connected between polished rod with subframe, vehicle body, there is damping and waterproof
Function, thus reach improve bolt head intensity and improve the effect of bolt anti-fatigue life.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings technical solution of the present invention is described further:
Accompanying drawing 1 is the structural representation of a kind of self-expanding bolt of the present invention；
Wherein: 1-head；2-ring flange；3-polished rod；4-threaded rod；5-self-expanding sealing strip.
Detailed description of the invention
Below in conjunction with the accompanying drawings and specific embodiment the present invention is described in further detail.
As shown in Figure 1, a kind of self-expanding bolt of the present invention, the ring flange being connected with head 1 including head 1
2, polished rod 3 and threaded rod 4, has the axial bar groove of 8 groups and the most angularly array on described polished rod 3 periphery,
All described axial bar grooves are embedded with self-expanding sealing strip 5；Described expanding sealing strips is thermoplasticity EPT rubber packing
Bar.
A kind of self-expanding bolt of the present invention, the expanding sealing strips being arranged on polished rod is after ingress of air, through 1-8
Hour will expand more than 5 times of own vol, the gap filling being connected between polished rod with subframe, vehicle body, have damping with
Water-proof function, thus reach improve bolt head intensity and improve the effect of bolt anti-fatigue life.
Below it is only the concrete exemplary applications of the present invention, protection scope of the present invention is not constituted any limitation.All employings
The technical scheme that equivalents or equivalence are replaced and formed, within the scope of all falling within rights protection of the present invention.
Claims (3)
1. a self-expanding bolt, ring flange, polished rod and the threaded rod being connected with head including head, it is characterised in that: in institute
State the axial bar groove having many groups and circular array on polished rod periphery, be embedded with from swollen at all described axial bar grooves
Swollen sealing strip.
Self-expanding bolt the most according to claim 1, it is characterised in that: described axial bar groove seals with described self-expanding
Bar at least has 8 groups.
Self-expanding bolt the most according to claim 2, it is characterised in that: described expanding sealing strips is thermoplasticity EPDM
Rubber weather strip.
