In order to solve the above technical problems, the technical solution that the utility model uses is: providing a kind of circular pipe company
Binding structure, including air hose and the external pipe being socketed on air hose, the end that the external pipe is inserted on the air hose is to connect
Mouth end, the lateral wall of the interface end are equipped with a circle card slot, are provided with sealing ring in the card slot；The sealing ring it is transversal
Face is in inverted " t " font, and the sealing ring includes being set in the inner ring portion of the card slot slot bottom and being against in the external pipe
Outer ring portion on side wall；The left and right sides in the inner ring portion is against respectively on the left and right sides wall of the card slot；The outer ring portion
Fixation be set in the inner ring portion, the outer diameter in the outer ring portion is greater than the internal diameter of the external pipe；The interface end
There is annular slope surface, the annular slope surface is located between the end face and the card slot of the interface end, the annular on lateral wall
The outer diameter of slope surface is gradually increased from from the endface of the interface end to the card slot, the maximum outside diameter of the annular slope surface and institute
The outer diameter for stating interface end is equal.
Preferably, it is equipped with retaining ring close to the lateral wall of the interface end on the air hose, the outer diameter of the retaining ring is greater than
The internal diameter of the external pipe.
Preferably, the lateral wall of the interface end is equipped with a circle lug boss, and the outer diameter of the lug boss is less than described outer
The internal diameter in adapter tube road.
Preferably, the sealing ring is rubber seal.
Preferably, the air hose is integral type molding.
The beneficial effects of the utility model are: the utility model without anchor ear can easily realize external pipe and air hose it
Between sealed connection, reduce material cost, reduce workload, improve production efficiency；Its structure is simple, installs operation side
And good airproof performance just,.
Detailed description of the invention
Fig. 1 is a kind of schematic cross-sectional view of one preferred embodiment of circular pipe connection structure of the utility model；
Fig. 2 is the partial structurtes enlarged diagram in the portion A in Fig. 1.
The components in the drawings are labeled as follows: 1, air hose；2, external pipe；3, rubber seal；31, inner ring portion；32, outer
Circle portion；4, interface end；41, card slot；42, annular slope surface；43, lug boss；5, retaining ring.
Specific embodiment
The preferred embodiment of the utility model is described in detail with reference to the accompanying drawing, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, to make the protection scope of the utility model apparent clear
Define.
Fig. 1 and Fig. 2 are please referred to, the utility model embodiment includes:
A kind of circular pipe connection structure, comprising: air hose 1 and the external pipe 2 being socketed on air hose 1.On the air hose 1
The end for being inserted into the external pipe 2 is interface end 4, and the lateral wall of the close interface end 4 is equipped with retaining ring on the air hose 1
5, the outer diameter of the retaining ring 5 is greater than the internal diameter of the external pipe 2, can prevent the insertion external pipe 2 that air hose 1 is excessive.Institute
The lateral wall for stating interface end 4 is equipped with a circle card slot 41, is provided with rubber seal 3 in the card slot 41；The rubber seal
Circle 3 cross section be in inverted " t " font, the rubber seal 3 include be set in 41 slot bottom of card slot inner ring portion 31 and
It is against the outer ring portion 32 on 2 inner sidewall of external pipe；The left and right sides in the inner ring portion 31 is against the card slot 41 respectively
Left and right sides wall on, can prevent during the installation process rubber seal 3 moved left and right in card slot 41, guarantee 1 He of air hose
Stability and leakproofness after the socket of external pipe 2；The fixation in the outer ring portion 32 is set in the inner ring portion 31, described
