Abstract
The utility model discloses a kind of bellows interface, it comprises first interface, and described first interface outer surface fore-end processing in worm structure, and is movably equipped with nut on worm structure; Described first interface internal surface processing is in Screw hole structure; Be connected with the second interface in described first interface, and part is stretched out outside first interface; Described second interface outer surface processing in Screw hole structure with the use of worm structure.The features such as the utility model has reasonable in design, easy to use, stablizes durable, good seal performance, safe and reliable.
Description
Technical field
The utility model is specifically related to a kind of bellows interface.
Background technique
Along with the fast development of national economy, natural gas enters in each each resident family of community of city.
Can, along with the arrival of natural gas, the conveying of natural gas be most important, and natural gas is carried in corrugated conduit, ensure the safe transport of natural gas, and bellows interface occupies critical role, and its performance quality directly has influence on the Security of natural gas conveying.At present, on market, bellows interface is not durable, and regular stubborn turning round causes jointing to loosen, and sealing is poor, and leak air phenomenon, there is great potential safety hazard.Therefore, need to provide a kind of new technological scheme to solve.
Summary of the invention
In order to meet above-mentioned situation, the purpose of this utility model is to provide a kind of durable, and good airproof performance, jointing is stablized, and can avoid the phenomenon that leaks air, safe and reliable bellows interface.
The utility model is taked following technological scheme to realize:
A kind of bellows interface, it comprises first interface, it is characterized in that: described first interface outer surface fore-end processing in worm structure, and is movably equipped with nut on worm structure; Described first interface internal surface processing is in Screw hole structure; Be connected with the second interface in described first interface, and part is stretched out outside first interface; Described second interface outer surface processing in Screw hole structure with the use of worm structure.
As preferred embodiment, the front-end face of described first interface is provided with the first Sealing.
As preferred embodiment, described second interface front end face is processed with globoidal structure.
As preferred embodiment, described second interface front end face is provided with the second Sealing.
The utility model has following beneficial effect in sum: design of the present utility model has simply rational in infrastructure, easy to use, durable, jointing arranges firmly, good seal performance, is convenient to dismounting, effectively can avoid the generation of gas leak phenomenon, simultaneously can working life of extension fixture.
Accompanying drawing explanation
Fig. 1 is the utility model cross section structure schematic diagram;
Fig. 2 is the utility model first interface perspective view;
Fig. 3 is the utility model second interface cross section structure schematic diagram.
Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
As Figure 1-3, a kind of bellows interface, it comprises first interface 1, and the processing of first interface 1 outer surface fore-end in worm structure 11, and is movably equipped with nut 3 on worm structure 11; The processing of first interface 1 internal surface is in Screw hole structure 12; Be connected with the second interface 2 in first interface 1, and part is stretched out outside first interface 1; Second interface 2 outer surface processing in Screw hole structure 12 with the use of worm structure 21.
Further, the front-end face of first interface 1 is provided with the first Sealing 4.
Further, the second interface 2 front-end face is processed with globoidal structure 22.
Further, the second interface 2 front-end face is provided with the second Sealing 23.
The principle of the utility model design: adopt the setting of two layer interfaces more effectively can prevent gas leakage, all arranges Sealing at jointing simultaneously and can prevent gas leakage further.
Last it is noted that above embodiment only in order to illustrate the utility model and and technological scheme described by unrestricted the utility model; Therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment, those of ordinary skill in the art should be appreciated that and still can modify to the utility model or equivalent replacement; And all do not depart from technological scheme and the improvement thereof of the spirit and scope of the present invention, all should be encompassed in right of the present utility model.
