The utility model relates to a kind of element and the structure that bellows connects, especially a kind of bellows jump ring and corrugated pipe connector structure of being used for.
Background technique
It is very extensive that bellows is used in people's life, in use, bellows often need connect with other pipe, existing bellows Placement is such: bellows made the bigger back-up ring structure of external diameter foremost, and a nut sleeve is set on bellows, and thread section is set at the tube end that needs join, during connection, nut sleeve matches with thread section, along with nut sleeve is tightened gradually, nut sleeve is pressed in back-up ring the connection that realizes bellows on the pipe that joins tightly.There is following deficiency in such structural type:
1, during production and processing, need in advance nut sleeve is arranged on the bellows, again with bellows make the bigger back-up ring structure of external diameter foremost, add comparatively inconvenience in man-hour, cost of production is higher, stores, transports also comparatively inconvenience simultaneously;
2, because the back-up ring structure is painstaking position, damage easily, in case back-up ring structural failure then cause scrapping of whole bellows, user cost is higher.
Therefore people wish the back-up ring structure is made movable, but because the crimp ring bore on the bellows body is bigger, movable back-up ring structure needs concrete following 2 points:
1, should walk around crimp ring and enter in the groove between the crimp ring;
2, can not drop out again after in the groove between crimp ring, and can bear bigger coupling mechanism force.
In the prior art, can't find out and to satisfy above-mentioned element at 2, bring inconvenience to use.
Summary of the invention
The purpose of this utility model is a kind of bellows jump ring and the corrugated pipe connector structure that designs for the deficiency that solves above-mentioned technology, described bellows jump ring can easily be put on the bellows body groove between the crimp ring and can not drop out again simultaneously, and can bear bigger coupling mechanism force; Described corrugated pipe connector structure difficulty of processing is little, and user cost is low.
The bellows jump ring that the utility model is designed, it comprises the jump ring body, described jump ring body is the semi-closed structure that is mainly connected a back side opening that forms at least by the jump ring sheet of two circular arcs, is provided with V-notch at the place of interconnecting of jump ring sheet.
As preferably, the identical and radian summation of described jump ring plate shape is 360 °, can form the annulus of a sealing after jump ring clamps together like this, and is stressed more even during locking.
As preferably, the width at the place of interconnecting of described jump ring sheet is a jump ring sheet width
Extremely
Like this, can effectively guarantee the join strength of jump ring sheet.
As preferably, described jump ring sheet is two or three, and like this, structure is comparatively simple, and it is comparatively convenient to use.
The corrugated pipe connector structure that the utility model is designed, it comprises bellows and connecting tube, an end that joins at connecting tube and bellows is provided with thread section, is provided with above-mentioned bellows jump ring on bellows; Also be provided with gland nut on the described bellows, this gland nut one end is threaded with described thread section, and the other end is provided with the bellows jump ring is limited in limit structure in the gland nut.
As preferably, described limit structure is the internal projecting ring structure of advancing to the screw convex on the gland nut.
As preferably, be provided with pad between described bellows and the connecting tube, can effectively improve sealing like this.
As preferably, described connecting tube two ends all are provided with thread section, and two ends all are connected with bellows by gland nut, are provided with the ring that holds out against of projection on the connecting tube between the thread section of two ends.
The bellows jump ring of the utility model gained owing to be semi-closed structure, can be put into the groove between the crimp ring on the bellows body like a cork, can not drop out in groove again after clamping together, and can bear bigger coupling mechanism force.The corrugated pipe connector structure of the utility model gained, after adopting above-mentioned bellows jump ring, bellows need not to make the bigger back-up ring structure of external diameter foremost, process more convenient, and jump ring, gland nut can be placed apart, and it is comparatively convenient to install, and can change after jump ring damages, and can not cause scrapping of whole bellows, effectively reduce user cost.
