Abstract

The utility model discloses a bellows. The bellows comprises a bellows body, ripples on the bellows body are arranged spirally, and the two ends of the bellows body are respectively provided with a connection mechanism. The bellows is characterized in that each connection structure comprises a nut, an opening retainer ring, a sealing gasket and a connector; each nut is provided with a through hole into which the bellows body is inserted; the position, close to one end portion ripple concave position, of the bellows body is sleeved with one opening retainer ring; each opening retainer ring is clamped and blocked in the threaded hole wall of the corresponding nut so as to avoid falling off of the nut; one nut is in threaded connection with one corresponding connector; one sealing gasket is arranged between one connector and the connected end face of the bellows body. The bellows has the advantages of being simple and compact in structure, and long in service life.

Description

Bellows
Technical field
The utility model is a kind of bellows.
Background technique
Bellows is installed in liquid conveying system as a kind of flexible pressure-resistant pipe fitting, in order to compensate the mutual displacement of pipeline or machine, equipment connection end, absorbing vibrational energy, can play the effects such as vibration damping, noise reduction, there is flexible, the multinomial feature such as quality is light, corrosion-resistant, antifatigue, high-low temperature resistant.
The crest of existing bellows easily weares and teares after being in permanent use, causes and breaks, thereby affect working life.
And existing corrugated pipe connection structure is optimized not enough, simple.
Summary of the invention
The utility model to solve existing bellows easily wearing and tearing with and the technical problem optimized not of linkage structure.
The technical scheme in the invention for solving the above technical problem is:
The utility model discloses a kind of bellows, comprises ripple supervisor, and described ripple supervisor's ripple is spiral setting, at ripple supervisor two ends, is respectively provided with a linkage structure, it is characterized in that: described linkage structure comprises nut, expanding ring, seal washer and joint; Described nut has the through hole that inserts bellows main body; Described ripple supervisor is arranged with an expanding ring near end corrugation recess, and described expanding ring locks in the screw wall of nut, avoids coming off of nut; The described nut joint that is spirally connected; Between the end face being connected with ripple supervisor at joint, be provided with seal washer.
Described ripple supervisor's outer surface is moulded with one deck cover.
Described seal washer is silicone gasket.
The technique effect that the utility model can reach is:
Bellows structure of the present utility model is compact, novel, and sealing is strong, and moulds at the attached one deck cover of bellows outer surface, bellows is played to the effect of a protection.
Accompanying drawing explanation
Fig. 1 is the three-dimensional exploded view of the utility model bellows;
Fig. 2 is the structural representation of the utility model bellows.
Description of reference numerals in figure:
1 is ripple supervisor; 2 is nut;
3 is expanding ring; 4 is seal washer;
5 is joint; 6 is through hole.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Refer to Fig. 1,2, the utility model provides a kind of bellows, comprises ripple supervisor 1, and described ripple supervisor's 1 ripple is spiral setting, at ripple, be responsible for 1 two ends and be respectively provided with a linkage structure, it is characterized in that: described linkage structure comprises nut 2, expanding ring 3, seal washer 4 and joint 5; Described nut 2 has the through hole 6 that inserts bellows main body; Described ripple supervisor 1 is arranged with an expanding ring 3 near end corrugation recess, and described expanding ring 3 locks in the screw wall of nut 2, avoids coming off of nut 2; Described nut 2 joint 5 that is spirally connected; At joint 5, be responsible between 1 end face being connected and be provided with seal washer 4 with ripple.
It is raw material that this ripple supervisor 1 adopts stainless steel, and join and joint 5 at two, and described joint 5 is brazed joint, by nut 2, it is connected with ripple supervisor 1, and described nut 2 is brass screw thread nut; Good for the firm and sealing that guarantees to be connected, all adopts expanding ring 3 that nut 2 is stuck ripple supervisor 1 near two end part ripple recess, has avoided nut 2 to come off; In order to guarantee sealing, special at joint 5 and ripple, be responsible between 1 end flat and use seal washer 4, joint 5 screw threads to adopt outer bevel-type inch screw thread connection, so more guaranteed the sealing of connection.
Described ripple supervisor's 1 outer surface is moulded with one deck cover.
Described cover is moulded as PVC.When increase is attractive in appearance, again ripple supervisor 1 is played a protective role.
Described seal washer 4 is silicone gasket.
In sum, bellows structure of the present utility model is novel, compact, and sealability is excellent, and the cover of outer surface is moulded and made bellows more durable, long service life.
