As shown in fig. 1 to 3, a novel air pipe joint comprises a joint sleeve 1, a sealing ring 2 concentrically embedded in the joint sleeve 1, a clamp spring ring 3 embedded in an opening at the right end of the joint sleeve 1 and positioned at the right side of the sealing ring 2, and a button sleeve 4 movably inserted in the opening at the right end of the joint sleeve 1 and positioned at the right side of the clamp spring ring 3; a limiting ring 41 is formed outwards at the opening at the root part of the button sleeve 4, a first annular conical surface 42 is formed at the outer edge of the opening at the end part of the limiting ring 41, and the first annular conical surface 42 is matched with the clamp spring coil 3; during the use, inwards press the tip of button cover 4 with the hand and move left in order to drive spacing collar 41, and then oppress the central card hole of jump ring 3 and warp left a certain angle, then turn left one end of hose 7 from the right side and pass button cover 4 in proper order, jump ring 3 and sealing washer 2 and insert the inside of adapter sleeve 1, the inner wall cover of sealing washer 2 is established on hose 7 outer wall in order to play sealed effect, at last with the tip of the button cover 4 of hand release, jump ring 3 will reset so that its inner wall hugs closely the outer wall of hose 7 with the help of self bounce, just so fix hose 7 in adapter sleeve 1, simultaneously, jump ring 3 can promote spacing collar 41 right when reseing in order to accomplish the reseing of button cover 4, above-mentioned principle is prior art, and the utility model has the characteristics of: a first reaming part 101 is formed on the inner wall of the opening at the right end of the joint sleeve 1, a clamping sleeve 5 is further embedded in the first reaming part 101, the root of the button sleeve 4 is movably inserted in the clamping sleeve 5, a second reaming part 52 is formed on the inner wall of the opening at the left end of the clamping sleeve 5, the limiting ring 41 is inserted in the second reaming part 52, and the root of the limiting ring 41 is matched with the bottom surface of the second reaming part 52; a third reaming part 51 is formed on the inner wall of the opening of the second reaming part 52, the clamp spring coil 3 is embedded in the third reaming part 51, a limiting sleeve 6 is further embedded at the opening of the third reaming part 51, the limiting sleeve 6 is arranged on the right side of the sealing ring 2, and the root of the limiting sleeve 6 is tightly pressed on the edge of the clamp spring coil 3; the outer wall of the right end of the cutting sleeve 5 is provided with at least two open grooves 53 which are uniformly distributed along the circumferential direction at equal angles, and the bottom of each open groove 53 is intersected with the inner wall of the second reaming part 52.

The inboard edge of the root opening part of stop collar 6 is formed with second annular conical surface 61, and second annular conical surface 61 mutually supports with jump ring circle 3 for the space is provided to the deformation of jump ring circle 3.

An annular cavity 102 is formed in the bottom surface of the first reamer part 101, and the end of the stop collar 6 is embedded in the annular cavity 102.

A chamfered edge 54 is formed on the inner side edge of the right end opening of the cutting sleeve 5.

During assembly: firstly, the clamp spring coil 3 is arranged in the third reaming part 51, and then the right end of the limiting sleeve 6 is pressed into the opening of the third reaming part 51 and tightly presses the root part of the clamp spring coil 3; then, the limiting ring 41 on the button sleeve 4 is inserted into the right end of the cutting sleeve 5 from right to left by utilizing the mutual matching of the first annular conical surface 42 and the chamfered edge 54, and because the outer diameter of the limiting ring 41 is larger than the inner wall of the right-end opening of the cutting sleeve 5, when the limiting ring 41 is inserted into the right-end opening of the cutting sleeve 5, the right-end opening of the cutting sleeve 5 can be elastically expanded outwards to a certain extent by means of the arrangement of each open slot 53 and the self elasticity until the limiting ring 41 completely passes through the right-end opening of the cutting sleeve 5 and is inserted into the second reaming part 52; finally, the ferrule 5 is pressed into the first counterbore 101 and the left end of the stop collar 6 is inserted into the annular cavity 102.

When in use: one end of the hose 7 sequentially penetrates through the button sleeve 4, the clamp spring ring 3 and the sealing ring 2 from right to left and is inserted into the joint sleeve 1, and finally, the end part of the button sleeve 4 is loosened by a hand, the clamp spring ring 3 is reset by means of the rebound force of the clamp spring ring 3, so that the inner wall of the clamp spring ring clings to the outer wall of the hose 7, and the hose 7 is fixed in the joint sleeve 1; because the right-hand member opening part of cutting ferrule 5 can rely on the setting of every open slot 53 and rely on self elasticity and outside elasticity extension certain degree, so can suitably increase the wall thickness of cutting ferrule 5 and spacing collar 41 and the size of the 4 wall thickness difference a of button cover, when the internal gas pressure of joint cover 1 is too big, because spacing collar 41 and the 4 wall thickness difference a of button cover are great, and receive the restriction of cutting ferrule 5, the root of spacing collar 41 can be firmly locked by the bottom surface of second reaming part 52, and then can not break away from cutting ferrule 5 because of too big atmospheric pressure, thereby the joint strength of hose 7 has been promoted in order to show the pressure resistance that promotes by a wide margin.

The utility model discloses it impresses in adapter sleeve 1 indirectly with the help of cutting ferrule 5 to press button cover 4 to set up two at least open slots 53 on cutting ferrule 5 in order to do benefit to the impressing of button cover 4, just so can all increase the wall thickness of adapter sleeve 1 and button cover 4 under the prerequisite that does not influence the assembly, and then broken through the restriction of the wall thickness of adapter sleeve 1 and button cover 4 to pressure resistance, thereby by a wide margin promotion pressure resistance in order to enlarge application scope.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those skilled in the art that various changes in the embodiments and modifications thereof may be made, and equivalents may be substituted for elements thereof; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
