Implement this utility model embodiment, have the advantages that and of the present utility model carry elongation type antirust bolt
Inside carries tensile inner bolt, is used together with supporting pad and nut and can fix two thicker parts, is suitable for model
Enclose wider, in bolt, set up liquid-leaking nozzle, bolt surface and neighbouring hydrops can be dredged, prevent bolt to be chronically in hydrops
Get rusty.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, the accompanying drawing in describing below is only
It is embodiments more of the present utility model, for those of ordinary skill in the art, in the premise not paying creative work
Under, it is also possible to other accompanying drawing is obtained according to these accompanying drawings.
Fig. 1 is the structural representation carrying elongation type antirust bolt that this utility model provides；
Fig. 2 is the longitudinal section structural representation carrying elongation type antirust bolt that this utility model provides.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
This utility model provides one and carries elongation type antirust bolt, and referring to Fig. 1 and Fig. 2, Fig. 1 is that this practicality is new
The structural representation carrying elongation type antirust bolt that type provides；Fig. 2 be this utility model provide carry the antirust spiral shell of elongation type
The longitudinal section structural representation of bolt.This carries elongation type antirust bolt and includes bolt head 10, groove the 11, first through hole 12, screw rod
20, the second through hole 21, recess the 22, first external screw thread 23, inner bolt the 30, first liquid-leaking nozzle the 31, second external screw thread 32, rubber closure 40
And second liquid-leaking nozzle 41.
Bolt head 10 is hexagon bolt head, is provided with groove 11, and the center of groove 11 offers the first through hole 12.
Screw rod 20 and bolt head 10 are connected away from one end of groove 11 is fixing.Offer on the vertical direction at screw rod 20 center
The second through hole 21 being connected with the first through hole 12, the second through hole 21 diameter is more than the first through hole 12.Screw rod 20 is away from bolt head 10
One end on offer recess 22, recess 22 is connected with the second through hole 21.The first external screw thread it is provided with on the outer surface of screw rod 20
23。
Inner bolt 30 is arranged in the first through hole 12, and the diameter of the both ends open of the first through hole 12 is respectively less than inner bolt 30
The diameter of inner bolt head, inner bolt head is circular bolt head.The second external screw thread 32 it is provided with on the inner screw surface of inner bolt 30,
The first liquid-leaking nozzle 31 is offered on the vertical direction at inner bolt 30 center.
Rubber closure 40 is arranged in recess 22, is connected together with recess 22.Being provided centrally with and the first leakage of rubber closure 40
Second liquid-leaking nozzle 41 of fluid apertures 31 connection.
It is provided with antirust coat on the hole inwall of first through hole the 12, second through hole 21 and the first liquid-leaking nozzle 31 (not scheme
Show).
Use this carry elongation type antirust bolt fix two parts time, if the thickness of part is excessive, screw rod 20 is not
Enough the longest time, then take out rubber closure 40, make inner bolt 30 outwards skid off from screw rod 20, until the inner bolt head of inner bolt 30 is the
The outlet of two through holes 21 is blocked, it is impossible to till elongating again.Screw rod 20 after increasing the most again inserts in the hole of two parts, inserts
After entering, then at inner bolt 30 away from pad supporting with the screw of part and inner bolt 30 on one end set of bolt head 10
Sheet, overlaps top nut the most again outside pad, tightens.Table when the large-scale bolt head 10 carrying elongation type antirust bolt
Face and neighbouring on when having hydrops, hydrops can be flowed into the first leakage of the inner bolt 30 in the second through hole 21 along with the first through hole 12
In fluid apertures 31, if rubber closure does not takes out, hydrops can enter in the second liquid-leaking nozzle 41, thereafter lets out, if rubber closure takes out,
Bolt is in elongation state, then hydrops can directly be discharged from the second liquid-leaking nozzle 41.
Implement this utility model embodiment, have the advantages that and of the present utility model carry elongation type antirust bolt,
Inside carries tensile inner bolt, is used together with supporting pad and nut and can fix two thicker parts, is suitable for model
Enclose wider, in bolt, set up liquid-leaking nozzle, bolt surface and neighbouring hydrops can be dredged, prevent bolt to be chronically in hydrops
Get rusty.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all at this
Within the spirit of utility model and principle, any modification, equivalent substitution and improvement etc. made, should be included in this utility model
Protection domain within.
