Description
Technical field
The utility model belongs to technical field of pipeline connection, is specifically related to a kind of pipeline spigot-and-socket linkage structure.
Background technique
Publication number is that the Chinese patent of CN203131261U discloses a kind of pipeline socket joint, comprise pipe socket, pipeline socket, pipeline socket is coaxially inserted in pipe socket, the groove of helix structure is provided with between pipe socket and pipeline socket, the steel wire of outer wrap rubber is provided with in groove, pipe socket and pipeline socket radial direction are provided with some threaded jacks, and pipe socket screws in jack with pipeline socket by bolt and is fixedly connected with.Although this pipeline socket joint has the advantage of good airproof performance to a certain extent, owing to being provided with the groove of helix structure between pipe socket and pipeline socket, cause pipe socket and pipeline socket difficult forming, namely processing cost increases; In addition, owing to being provided with groove between pipe socket and pipeline socket, causing the structural strength of pipe socket and pipeline socket to reduce, cannot requirement of strength be met.
Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of pipeline spigot-and-socket linkage structure, has the advantage of the high and good seal performance of easy-formation, intensity.
For achieving the above object, the utility model provides following technological scheme:
A kind of pipeline spigot-and-socket linkage structure, comprises and is separately positioned on coupling faucet on adjacent two pipelines and connection socket, be provided with seal ring between described coupling faucet and connection socket; Described seal ring comprises seal ring body, the central through bore for being sleeved on described connection socket periphery wall is provided with in described seal ring body, and one end of described seal ring body is positive stop end, described positive stop end is provided with for the limit structure that coordinate spacing with described connection socket; The periphery wall of described seal ring body is interval with cross section indentation and the sealing tooth of inwall interference fit with described coupling faucet.
Further, described limit structure comprises retaining wall in the endoporus for being sleeved on described connection socket, forms the limited impression be contained in for stop collar on described connection socket end face between described interior retaining wall and described seal ring body.
Further, the described sealing flank of tooth is the plane with the axes normal of described central through bore to the side sidewall that the side sidewall of described positive stop end is the conical surface, dorsad described positive stop end.
Further, the both sides sidewall of described sealing tooth is the conical surface, and in the both sides sidewall of described sealing tooth, the conical degree of conical surface towards the side sidewall of described positive stop end is less than or equal to the conical degree of conical surface of the side sidewall of described positive stop end dorsad.
The beneficial effects of the utility model are:
Pipeline spigot-and-socket linkage structure of the present utility model, by arranging seal ring between coupling faucet and connection socket, and by ring set on connection socket, coordinates by limit structure and connection socket are spacing; So, when connecting, directly can utilize the inwall interference fit of sealing tooth and coupling faucet, realizing being tightly connected; Because seal ring is directly sleeved on connection socket by central through bore, therefore, do not need to arrange seal groove on connection socket outer wall, and by sealing tooth and coupling faucet interference fit, do not need to arrange seal groove on the inwall of coupling faucet yet, namely coupling faucet is consistent with the uniform wall thickness of connection socket, is easy to shaping; Owing to not needing to arrange seal groove, the structural strength of coupling faucet and connection socket is also better.
Accompanying drawing explanation
In order to make the purpose of this utility model, technological scheme and beneficial effect clearly, the utility model provides following accompanying drawing to be described:
Fig. 1 is the structural representation of the utility model pipeline spigot-and-socket linkage structure embodiment;
Fig. 2 is the structural representation of seal ring.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, and to make those skilled in the art better can understand the utility model being implemented, but illustrated embodiment is not as to restriction of the present utility model.
As shown in Figure 1, be the structural representation of the utility model pipeline spigot-and-socket linkage structure embodiment.The pipeline spigot-and-socket linkage structure of the present embodiment, comprises and is separately positioned on coupling faucet 1 on adjacent two pipelines and connection socket 2, be provided with seal ring 3 between coupling faucet 1 and connection socket 2.Seal ring 3 comprises seal ring body 4, is provided with the central through bore 5 for being sleeved on connection socket 2 periphery wall in seal ring body 4, and one end of seal ring body 4 is positive stop end, and positive stop end is provided with for the limit structure that coordinate spacing with connection socket 2; The periphery wall of seal ring body 4 is interval with cross section indentation and the sealing tooth 6 of inwall interference fit with coupling faucet.Sealing tooth 6 is set to multiple tracks, and the present embodiment is provided with 5 road sealing teeth 6, and the quantity of sealing tooth 6 is determined according to actual, is as the criterion to meet sealing requirements.
Further, the limit structure of the present embodiment comprises retaining wall 7 in the endoporus for being sleeved on connection socket 2, the limited impression 8 be contained in for stop collar on connection socket 2 end face is formed between interior retaining wall 7 and seal ring body 4, by arranging limited impression 8, can to realize between connection socket 2 spacing coordinates, and during use, can first be sleeved on connection socket 2 by seal ring 3, then directly connection socket 2 is inserted in coupling faucet 1, easy to operate.
Further, the sealing tooth 6 of the present embodiment is the plane with the axes normal of central through bore 5 towards the side sidewall that the side sidewall of positive stop end is the conical surface, dorsad positive stop end.Certainly, sealing tooth 6 can also all be set to the conical surface for both sides sidewall, and in the both sides sidewall of sealing tooth, the conical degree of conical surface towards the side sidewall of positive stop end is less than or equal to the conical degree of conical surface of the side sidewall of positive stop end dorsad.Adopt the sealing tooth 6 of this structure, when with coupling faucet 1 interference fit, suitably can be out of shape, not only can strengthen sealability, and the deformation force of sealing tooth 6 effectively can strengthen the join strength between coupling faucet 1 and connection socket 2.
The pipeline spigot-and-socket linkage structure of the present embodiment, by arranging seal ring between coupling faucet and connection socket, and by ring set on connection socket, coordinates by limit structure and connection socket are spacing; So, when connecting, directly can utilize the inwall interference fit of sealing tooth and coupling faucet, realizing being tightly connected; Because seal ring is directly sleeved on connection socket by central through bore, therefore, do not need to arrange seal groove on connection socket outer wall, and by sealing tooth and coupling faucet interference fit, do not need to arrange seal groove on the inwall of coupling faucet yet, namely coupling faucet is consistent with the uniform wall thickness of connection socket, is easy to shaping; Owing to not needing to arrange seal groove, the structural strength of coupling faucet and connection socket is also better.
The above embodiment is only for absolutely proving the preferred embodiment that the utility model is lifted, and protection domain of the present utility model is not limited thereto.The equivalent alternative or conversion that those skilled in the art do on the utility model basis, all within protection domain of the present utility model.Protection domain of the present utility model is as the criterion with claims.
