Abstract
The utility model discloses a corrugated pipe joint structure which comprises a joint connected with a corrugated pipe. A retainer ring is arranged at the front end of the joint, a connection nut is sleeved at the rear end of the retainer ring on the joint, a seal ring is sleeved at the front end of the retainer ring, and a gasket with the side wall open is sleeved at the rear end of the retainer ring. The gasket comprises a positioning wall and a flange, wherein the positioning wall penetrates through an inner hole of the connection nut, and the flange extends to the outer periphery to be abutted against the retainer ring. The gasket sleeved on the joint fills a clearance between the connection nut and the joint, so that radial displacement of the joint during screwing of the connection nut is avoided, and better tightness between the end of the joint and a mounting portion of equipment is achieved. In addition, the flange is clamped between the retainer ring and the connection nut after the connection nut is locked, and since the retainer ring has certain ductility, higher pre-tightening force can be applied in screwing of the connection nut, and firmness in connection between the integral corrugated pipe and the equipment can be well guaranteed.
Description
Technical field
The utility model belongs to the tube connection piece technical field of structures, is specifically related to a kind of structure technology of bellows structure.
Background technique
The bellows of existing technology generally connects two joints so that is connected with equipment at two ends, and the mode that the general employing of modal joint is threaded promptly is provided with a back-up ring in the joint outer end, and the assembly department of a sheathed locking nut and equipment is spirally connected at the back-up ring rear.But locking nut is general and joint between also have certain clearance; In the process of locking nut of screwing; Can not strict aim between joint and the equipment assembly department, perhaps cause the seal washer distortion that is arranged between them, thereby the join strength and the sealability of bellows integral body impacted.
Summary of the invention
The purpose of the utility model is: the deficiency to existing technology exists, a kind of compactness rational in infrastructure is provided, and help bellows to connect the corrugated pipe connector structure of close and firm.
For realizing the purpose of the utility model; Adopt following technological scheme to be achieved: a kind of corrugated pipe connector structure; Include the joint that is connected with bellows, the joint front end is provided with back-up ring, and the rear end of back-up ring is arranged with the attaching nut on the joint; Described back-up ring front end sleeve is provided with seal ring, and the back-up ring rear end is arranged with the packing ring of sidewall opening.
As preferred version: described packing ring comprises the location wall that passes attaching nut's endoporus, and extends outside and prop up the convex edge of back-up ring.
As preferred version: described packing ring is by the polyvinyl plastics integrated injection molding.
Compared with prior art; The beneficial effect of the utility model is: since on joint sheathed packing ring; Packing ring has been filled up the gap between attaching nut and the joint; Make the attaching nut not produce displacement radially, make the sealability between joint end and the equipment assembly department better at the process middle joint of screwing.Convex edge on the packing ring is stuck between back-up ring and the attaching nut after attaching nut locking in addition, because packing ring has certain ductility, can apply bigger pretightening force when the attaching nut screws, and has guaranteed firm connection the between bellows integral body and the equipment well.

Fig. 1 is the structural representation of the utility model.
1, bellows; 2, joint; 3, attaching nut; 4, packing ring; 41, location wall; 42, convex edge; 5, back-up ring; 6, seal ring; 7, assembly department.
Embodiment
According to accompanying drawing the embodiment of the utility model is done a detailed explanation below.
According to shown in Figure 1; The described a kind of corrugated pipe connector structure of present embodiment; Include the joint 2 that is connected with bellows 1, joint 2 front ends are provided with back-up ring 5, and the rear end of back-up ring 5 is arranged with attaching nut 3 on the joint 2; Described back-up ring 5 front end sleeves are provided with seal ring 6, and back-up ring 5 rear ends are arranged with the packing ring 4 of sidewall opening.
Promptly near an end of joint 2 ports, the rear end is the end that joint 2 is connected with bellows 1 to the described front end of each parts.
Described packing ring 4 comprises the location wall 41 that passes attaching nut's 3 endoporus, and extends outside and prop up the convex edge 42 of back-up ring 5.Described location wall 41 is 42 direction progressive additives along the convex edge.When attaching nut 3 be connected on the assembly department 7 on the equipment and locking process gradually in, being connected in the attaching nut 3 between week and the packing ring 4 is also tight more.
Described packing ring 4 is by the polyvinyl plastics integrated injection molding.Because packing ring 4 sidewalls are opening and comparatively soft, packing ring 4 just can be set on the joint 2 easily like this, and described packing ring 4 is still leaving certain interval between its two ends under the situation of adjacent joint 2 peripheries, and is inconsistent to prevent packing ring 4 two ends.
