Description
Technical Field
The utility model belongs to the technical field of bellows interface structure, relate to a bellows connection structure more in detail.
Background
The existing corrugated pipe interface adopts a connecting structure that a wave beater is adopted to flatten the port of the corrugated pipe, then a flat gasket is arranged between the flattened port and a connecting joint, and a nut is used for screwing and fixing. However, the connection structure requires a flat cutting port, the wave breaker cannot deform after wave breaking, and a wave breaker tool is required, so that the connection structure is inconvenient to carry and low in construction efficiency.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem who mentions among the background art, the utility model provides a bellows connection structure, this connection structure need not to use the ware of beating the ripples, and it is not high to the requirement of port roughness, has reduced the construction degree of difficulty, improves and takes over efficiency.
The utility model adopts the technical proposal that:
a corrugated pipe connecting structure comprises a corrugated pipe, a sealing ring, a loose joint nut, a U-shaped snap ring and an external thread joint; the sealing washer cup joints in the recess of bellows port department, the loose joint nut with outer screwed joint threaded connection the loose joint nut with set up between the port of outer screwed joint the U-shaped snap ring, U-shaped snap ring joint is in on the bulge loop of bellows.
In the above corrugated pipe connection structure, the sealing ring is an O-shaped sealing ring.
In the above corrugated pipe connection structure, the O-shaped sealing ring and the port of the corrugated pipe sleeved with the O-shaped sealing ring are inserted into the port of the external thread joint.
In the corrugated pipe connecting structure, the loose joint nut is internally provided with a stepped groove, and the U-shaped snap ring is clamped on the end surface of the stepped groove.
In the corrugated pipe connecting structure, the outer diameter of the convex ring of the corrugated pipe is smaller than the inner diameter of the interface of the outer wire joint, the O-shaped sealing ring is sleeved in the groove at the port of the corrugated pipe, and the outer diameter of the O-shaped sealing ring is larger than the inner diameter of the interface of the outer wire joint. The arrangement is mainly convenient for installation and reliable sealing performance of the O-shaped sealing ring.
The technical effects of the utility model are as follows:
the loose joint nuts are used for connection, so that the connection firmness is ensured; the loose joint nut is adopted for fastening, and the U-shaped snap ring is used for clamping the convex ring of the corrugated pipe, so that the corrugated pipe is further prevented from loosening; the O-shaped sealing ring is in interference fit with the interface of the external thread joint, so that the sealing property is further ensured; therefore, the utility model discloses it is firm to have the connection, and sealing performance is good to easy operation need not the ware of beating, has improved takeover speed.
