Description
Technical field
A kind of stopper structure is the utility model is related to, especially a kind of Novel air seal plug structure.
Background technology
The parts in automobile engine will largely carry out air-leakage test at present, had to when doing pneumatic sealing test by
Hole around test chamber with external world's insertion blocks, and toward interacvity air-filling and then detects.Now will to workpiece upper screwed hole mouth chamfering
The hermetic seal closure mode for seeking SAE J1926-1 either J6149-1 standards is to be pressed in hole using standard O-ring or block rubber
Sealed in plane where mouthful.It is qualified to frequently occur in family and do hermetic seal, and in client, that assembling is but oozed
There is the unqualified situation of leakage rate in water, gas leakage or test.Its reason is closure mode and the client assembling side of this kind of hole hermetic seal
Formula is inconsistent, sealing region sealing function region used when being not client's assembling.Now meet SAE for threaded bores chamfering
The hole closure of J1926-1 or J6149-1 standards uses a kind of new block head, and it is that block head is pressed in aperture that it, which blocks principle,
The chamfering conical surface on sealed.
Utility model content
The purpose of this utility model is to provide a kind of Novel air seal plug structure, to solve to carry in above-mentioned background technology
The problem of going out.
The purpose of this utility model is achieved by following technical proposals：A kind of Novel air seal plug structure, bag
Plug, cavity, seal and plush copper are included, the cavity is arranged on the inside in the preceding stage casing of plug；The plush copper is arranged on plug
Tail end, and an annular groove is formed between plug；The seal is fixedly mounted in annular groove, and the seal and institute
The tail end for stating plush copper flushes.
Further, the plug and plush copper are structure as a whole.
Further, the plug is step structure.
Further, the seal is made up of elastomeric material.
Further, the front end of the seal is provided with chamfering.
Compared with prior art, the beneficial effects of the utility model are new a kind of Novel air seal plug structures, knot
Structure is simple, and air-tightness is good, testing result accurately and reliably, using it is simple the advantages that, be adapted to promote the use of.
Brief description of the drawings
Fig. 1 is the utility model overall structure design sketch；
In figure：1- plugs, 2- cavitys, 3- seals, 4- plush coppers.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment, based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
As shown in figure 1, the utility model discloses a kind of Novel air seal plug structure, including plug 1, cavity 2, sealing
Body 3 and plush copper 4, the cavity 2 are arranged on the inside in the preceding stage casing of plug 1；The plush copper 4 is arranged on the tail end of plug 1, and and
An annular groove is formed between plug 1；The seal 3 is fixedly mounted in annular groove, and the seal 3 and the plush copper 4
Tail end flush, the plug 1 and plush copper 4 are structure as a whole, and the plug 1 is step structure, and the seal 3 is rubber
Material is made, and the front end of the seal 3 is provided with chamfering.
In use, blowing clean part, especially position, need block-up position, be then directed at the seal 3 on the plug 1
Position, need block-up position to be sealed, then tested by gas check.
New a kind of Novel air seal plug structure, simple in construction, air-tightness is good, and testing result accurately and reliably, uses
Simply.
It is obvious to a person skilled in the art that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, it can realize that this practicality is new in other specific forms
Type.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and is nonrestrictive, this practicality is new
The scope of type limits by appended claims rather than described above, it is intended that the equivalency fallen in claim is contained
All changes in justice and scope are included in the utility model.Any reference in claim should not be considered as limitation
Involved claim.
Moreover, it will be appreciated that although the present specification is described in terms of embodiments, not each embodiment is only wrapped
Containing an independent technical scheme, this narrating mode of specification is only that those skilled in the art should for clarity
Using specification as an entirety, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art
It is appreciated that other embodiment.
