Abstract
A kind of pipe connecting structure, including the connecting pin integrally formed positioned at pipe end and with pipeline, the connecting pin forms connecting end surface, connecting pin internal diameter is equal to pipe end outside diameter and central axis overlaps, the peripherally disposed threaded hole and location hole staggeredly on connecting end surface, the connecting end surface of relative duct size set corresponding threaded hole and pilot pin.By setting threaded hole and location hole staggeredly on conduit connection end face, quickly installation is realized on the basis of precise positioning；First groove, the second groove are further set respectively on location hole both sides, sealing ring is set in the first groove, the second groove, reaches better seal effect, when being particularly pipeline thermal medium；Connection structure provided by the utility model is easy for installation, and sealing effect is good.
Description
Technical field
It the utility model is related to tube body technical field, and in particular to a kind of pipe connecting structure.
Background technology
Connection generally use welding manner or threaded connection between pipeline, but tapping needs specific purpose tool on pipeline,
It is time-consuming and laborious, inefficiency.Furthermore environment is narrow at many pipe joints, it is unfavorable for being subjected to, that is, allows to carry out
Welding operation, but there are liquid in pipeline, this is a problem to be solved again.On the other hand existing various pipeline fast mountings
Connector cannot solve sealing problem well.Pipeline, the connection needs of PPR pipe largely used in production, life are a kind of both
The connection structure that rapid and convenient can be sealed reliably again.
Utility model content
The utility model is in order to solve the above technical problems, provide a kind of pipe connecting structure.
Technical problem to be solved in the utility model is realized using following technical solution.
A kind of pipe connecting structure, including the connecting pin integrally formed positioned at pipe end and with pipeline, the connecting pin
Connecting end surface is formed, connecting pin internal diameter is equal to pipe end outside diameter and central axis overlaps, along circle on connecting end surface
Circumferential direction sets threaded hole and location hole staggeredly, and the connecting end surface of relative duct size sets corresponding threaded hole and pilot pin.
It is further preferred that it is described lead to contact surface and be located in location hole and connecting pin the first groove is set between, the
First sealing ring is set in one groove, and connecting end surface sets the second groove between location hole and connecting pin outer, and second is recessed
Second sealing ring is set in groove.
It is further preferred that the positioning bore dia is less than screw thread bore dia, is quickly positioned and reached more preferably with realizing
Sealed connection effect.
It is further preferred that the location hole is blind hole or through hole.
It is further preferred that first groove, the second groove section are T-shaped, so as to when sealing ring is inserted into groove
Air is remained in discharge groove.
It is further preferred that the first slot opening diameter is less than the second slot opening diameter.
The beneficial effects of the utility model are：By setting threaded hole and location hole staggeredly on conduit connection end face,
Quickly installation is realized on the basis of precise positioning；First groove, the second groove are further set respectively on location hole both sides,
Sealing ring is set in the first groove, the second groove, reaches better seal effect, when being particularly pipeline thermal medium；This reality
Connection structure with new offer is easy for installation, and sealing effect is good.
Brief description of the drawings
Fig. 1 is utility model diagram；
Fig. 2 is Fig. 1 along A-A faces sectional view.
Embodiment
In order to make the technical means, creative features, achievable purpose and effectiveness that the utility model is realized easy to understand, under
Face combines and is specifically illustrating, and the utility model is expanded on further.
As shown in Figs. 1-2, a kind of pipe connecting structure, including positioned at 6 end of pipeline and the connection integrally formed with pipeline 6
End 1, connecting pin 1 form connecting end surface 7, and 1 internal diameter of connecting pin is equal to 6 end outside diameter of pipeline and central axis overlaps, and is located at
Peripherally disposed threaded hole 3 and location hole 4 staggeredly on connecting end surface 7, the connecting end surface setting of relative duct size are corresponding
Threaded hole and pilot pin, 4 diameter of preferred orientation hole are less than 3 diameter of threaded hole, are quickly positioned with realization and reach more preferably close
Connection effect is sealed, location hole 4 can be blind hole or through hole, and connecting end surface 7 is located in location hole 4 and connecting pin 1 to be set between
First groove 5,5 the first sealing ring of interior setting of the first groove, connecting end surface 7 are set between being located at 1 outer of location hole 4 and connecting pin
Second groove 2,2 the second sealing ring of interior setting of the second groove, the first groove 5,2 section of the second groove are preferably T-shaped, so as to close
Discharged when in seal insertion groove in groove and remain in air, 5 opening diameter of the first groove is less than 2 opening diameter of the second groove.
The advantages of basic principle and main feature and the utility model of the utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the present utility model is not limited to the above embodiments, described in above embodiments and description
Simply illustrate the utility model principle, on the premise of not departing from the spirit and scope of the utility model, the utility model is also
Various changes and modifications are had, these various changes and improvements fall within the scope of the claimed invention.The utility model
Claimed scope is defined by the appending claims and its equivalent thereof.
