Embodiment
Below in conjunction with accompanying drawing 3 ~ 6, the present invention will be further described, but therefore do not limit the present invention among described scope of embodiments.
As shown in Fig. 3 ~ 6, the tube connection device in the present embodiment comprises a housing 4 ' be made up of collet and upper cover.This collet and the equal homonymy of upper cover are formed in one, and the position that they are bordered on forms a fexible film, and upper cover can rotate around this fexible film thus close up with collet.Collet is also provided with two for clamping the chuck of pipe 6 to be connected.The structure of this joint body 1 is same as the prior art, does not repeat them here.
As shown in Figure 3, collet and on cover and be provided with three pairs of floors 5 symmetrically.The middle part being positioned at the floor on collet is provided with the recessed curve bath 52 for supported joint body, is provided with fovea superior curve bath 53 accordingly at the middle part of the floor being positioned at upper cover.When collet and upper cover close up, namely joint body 1 is folded between corresponding recessed curve bath 52 and fovea superior curve bath 53 (see Fig. 5 and 6).
As illustrated in Figures 5 and 6, be all inserted with a T-shape back-up ring 2 in two ends of this joint body 1, between the end of the joint body 1 of each T-shape back-up ring 2 and correspondence, be also provided with an elastic supporting mechanism.
As shown in Figure 4, described elastic supporting mechanism is the joint catch 7 of an annular, the joint catch 7 of this annular is provided with at least two legs 71 near the side of this joint body 1, an all sheathed spring 72 on each described leg, the free end of described leg 71 is provided with one for the collar flange of fixing spring 72; Be equipped with in the both sides of fovea superior curve bath and recessed curve bath one with the groove 51 of leg 71 adaptation, after collet and upper cover close up, groove 51 corresponding on the floor of correspondence has complemented each other to form a through hole, and described leg 71 is inserted in corresponding through hole respectively.One end of spring 72 presses on the surface of the outside side of described through hole, and the other end of spring 72 then presses on the inside side of annular joint catch 7.
This tube connection device also comprises one and extends to this housing 4 ' outside, for driving the moving in opposite directions plate of this T-shape back-up ring 2.This plate comprises the body 8 of an annular, has two protuberances 81 at the edge of the body 8 of annular; Be provided with a square groove 41 ' (see Fig. 3 and Fig. 6) extended along the medial axis of this joint body 1 in the upper position corresponding with this protuberance 81 of this housing 4 ', described protuberance 81 wears out the outside extending to this housing 4 ' from this square groove 41 '.
When pipe disassembles from joint body by needs, only need to stir plate, two plate relative movements thus drive T-shape back-up ring to draw close towards the inside of joint body, spring on joint catch is compressed, the state of opening with the radial direction be pushed into by the taper steel-tooth being positioned at joint body tip inside along joint body thus reach the object of unclamping pipe.
After decontroling two plates, under the effect of the restoring force of spring, the joint catch of annular resets and causes T-shape back-up ring to get back to original position, and taper steel-tooth also reverts to the state of stinging tight pipe.
Certainly, the joint catch being positioned at the T-shape back-up ring of joint body homonymy, plate and ring-type also can be arranged to integral type, thus reduces the number of components of tube connection device, improves assembling speed.The same T-shape back-up ring being positioned at joint body homonymy and plectrum, or the joint catch of the T-shape back-up ring and ring-type that are positioned at joint body homonymy all can be made of one formula.
