Abstract

A kind of connection structure of the metallic conduit it includes a pipe, a pipe connection with a fluid runner. The pipe connection is consisted of connection body and a connector the special point of it is that at the end of pipe sets up a ring with convex to the outside and the port of connector of the ring sets up a concave table and at inner side of the pipe of the ring with convex to the outside sets up a seal ring and at the side of the seal ring sets up a nut cap which is fixed connection with the connector. The invention compares with the technology existed has the merits as refined seal, uneasy leakage, easy to connect and detach, convenience and speed treatment, low cost and the connection of metallic conduit stabilize and reliable and so on.

Description

A kind of linkage structure of metal tube
Technical field:
Patent of the present invention relates to a kind of interconnection technique of pipe.
Background technique:
The connection of pipe at present generally is that Sealing is arranged between the end face that connects main body and pipe, be that the end face of tube and the end face crush seal rubber cushion of connecting head make the rubber cushion sealing, this method makes the rubber cushion easy deformation because rubber cushion does not have good positioning device, long easy seepage of time.And the interconnection technique of the another kind of traditional pipe that passes through to be threaded, how its seal for pipe joints is by sealer or sealant tape sealing, though this encapsulating method sealing effect is good, dismounting is inconvenient.
Summary of the invention:
It is a kind of tight-closed that the purpose of patent of the present invention is to provide, and is difficult for leaking, and connects dismounting easily, and easy to process quick, cheap, metal tube connects the linkage structure of reliable and stable metal tube.
The present invention realizes like this, comprise pipe, have the pipe joint of fluid passage, the connecting head that pipe joint links together by fittings body, with fittings body constitutes, its specialization is that the termination of pipe is provided with the ring of evagination, the connecting head port of corresponding ring is provided with concave station, the pipe of the ring inboard of evagination is provided with seal ring, and the side of seal ring is provided with block, and block is fixed together with connecting head.During connection, pipe is inserted in the concave station of connecting head, the ring of the evagination of pipe leans against on the concave station, and block abuts against on the seal ring, makes seal ring be close to the sidewall of the concave station of the side of ring of evagination of pipe and connecting head, and simultaneously, block is fixed together with connecting head.Owing to adopt the sealing means of the seal ring of exterior buckle type, seal ring is not easy displacement under the pipe positioning action, therefore, has tight-closedly, is difficult for leaking, and connects dismounting and is easy to characteristics.
Here, in order to make seal ring seal better on the sidewall of the concave station of the side of the ring of the evagination of pipe and connecting head, be provided with pressure ring between seal ring and block, the sidewall internal diameter of the external diameter of pressure ring and the concave station of connecting head matches.Owing to adopt pressure ring, make seal ring under the effect of pressure ring, the amount of distortion is big, helps bringing into play the effect of its sealing.
Be to be fixed together or by being threaded togather between block and connecting head by screw rod.
In order to make the seal ring easy deformation, with the sealability of lift-off seal ring, the inwall of seal ring is inner concavity, and the outer wall of seal ring is outer gibbosity.Like this, seal ring under the compressing of pressure at both sides, attenuation, simultaneously, its external diameter strengthens, and makes on sidewall of its concave station that is close to pipe outer wall and connecting head.
Compared with the prior art the present invention has tight-closedly, be difficult for to leak, and connects dismounting easily, and easy to process quick, cheap, metal tube connects reliable and stable advantage.

Embodiment
Embodiment 1: as shown in Figure 1, the present invention includes the pipe joint 2 of managing 1, having fluid passage 2a, the connecting head 2g that pipe joint 2 links together by fittings body 2f, with fittings body 2f constitutes, its specialization is to manage the ring 3 that 1 termination is provided with evagination, the connecting head 2g port 2b of corresponding ring 3 is provided with concave station 2c, the pipe 1 of ring 3 inboards of evagination is provided with seal ring 4, the side of seal ring 4 is provided with block 5, block 5 is provided with internal thread 5a, connecting head 2g is provided with outside thread 2d, and block 5, connecting head 2g screw thread are fixed together.Be provided with pressure ring 6 at seal ring 4 and 5 of blocks, the sidewall 2c1 internal diameter of the concave station 2c of the external diameter of pressure ring 6 and connecting head 1 matches.As shown in Figure 4, the inwall 4a of seal ring 4 is inner concavity, and the outer wall 4b of seal ring 4 is outer gibbosity.The connecting head 2g that links together with fittings body 2f has two or more.
Embodiment 2: as shown in Figure 2, the present invention is on embodiment 1 basis, and block 5 is provided with outside thread 5b, connecting head 2g is provided with internal thread 2e, and block 5, connecting head 2g screw thread are fixed together.
Embodiment 3: as shown in Figure 3, the present invention is on embodiment 1 basis, and block 5, connecting head 2 are fixed together by screw rod 7.
Embodiment 4: as shown in Figure 4, the present invention is on embodiment 1 basis, and the ring 3 of evagination constitutes by being arranged on the protruding 3a that manages on 1, the ring 3b that is positioned at protruding 3a side.
