2, movable sheath of the present utility model and dop cooperatively interact, convenient disassembly, but do not need instrument directly to use the hand installation or removal, dismounting is simple, and is time saving and energy saving, is not subjected to the restriction of mounting point, and using scope is wide;
3, movable sheath of the present utility model adopts plastic materials to make, light weight, and cost is low;
4, the utility model is applicable to pipeline and pipeline, the quick connection between pipeline and the valve.
Description of drawings:
Fig. 1 is a cross-sectional view of the present utility model.
Embodiment:
With specific embodiment the utility model is further described below, referring to Fig. 1:
The quick pipe connecting device, the housing 10 of tubulose is that large-diameter portion 101, middle part are that small diameter part 102 is formed by two ends, the middle part of the inner cylindrical surface of small diameter part 102 is provided with position limiting convex ring 106, be formed with step 105 at the large-diameter portion 101 at housing 10 two ends and the junction of small diameter part 102, be respectively arranged with in two large-diameter portions 101 of housing 10 and clamp assembly, at step 105 and clamp and be provided with seal ring 20 between the assembly; Described housing large-diameter portion 101 includes two sections by the internal diameter from interior ascending setting outward, is being provided with internal thread 104 than the large diameter place; The described assembly that clamps is followed successively by pressure cap 50 from outside to inside, movable sheath 40 and elastic chuck 30, described pressure cap 50 is: the outside of the external cylindrical surface of a hollow circular cylinder is outward extended with the projection 501 that may be stuck in housing two ends large-diameter portion 101 end faces, external cylindrical surface beyond the projection 501 is provided with the outside thread 502 that can match with housing internal thread 104, be provided with the step 503 that hole enlargement forms in the inboard of cylindrical inner cylindrical surface, described movable sheath 40 is: the cylindrical inboard of a hollow is provided with the conical surface 401 that diameter diminishes gradually, and the big footpath of conical surface 401 is greater than cylindrical external diameter; The arranged outside of movable sheath 40 is spirally connected in pressure cap 50 and by outside thread on the pressure cap 50 502 and housing 10 and is arranged in the housing 10, be provided with elastic chuck 30 between seal ring 20 and movable sheath 40, the inboard of movable sheath 40 can be in 503 activities of the step in elastic chuck 30 and the pressure cap 50.
