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 ' being made up of collet and upper cover.The equal homonymy of this collet and upper cover is formed in one, and the position that they are bordered on forms a fexible film, thereby upper cover can rotate and close up with collet around this fexible film.On collet, be 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 symmetrically three pairs of floors 5.The middle part that is positioned at the floor on collet is provided with the recessed curve bath 52 for supported joint body, is provided with accordingly fovea superior curve bath 53 at the middle part of the floor that is positioned at upper cover.In the time that collet and upper cover close up, joint body 1 is folded between corresponding recessed curve bath 52 and fovea superior curve bath 53 (seeing 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 each T-shape back-up ring 2 and the end of corresponding joint body 1, 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, this annular joint catch 7 is provided with at least two legs 71 near a side of this joint body 1, equal sheathed spring 72 on each described leg, the free end of described leg 71 is provided with a collar flange for 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 adaptations, after collet and upper cover close up, groove 51 corresponding on corresponding floor has complemented each other to form a through hole, described leg 71 is inserted in respectively in corresponding through hole.One end of spring 72 presses on the surface of the outside side of described through hole, and the other end of spring 72 presses on the inside side of annular joint catch 7.
This tube connection device also comprise one extend 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 annular body 8; Be provided with in this upper position corresponding with this protuberance 81 of housing 4 ' square groove 41 ' (seeing Fig. 3 and Fig. 6) that extend a medial axis along this joint body 1, described protuberance 81 wears out the outside that extends to this housing 4 ' from this square groove 41 '.
When needs by pipe when joint body disassembles, only need to stir plate, thereby two plates relatively move and drive T-shape back-up ring to draw close towards the inside of joint body, spring on joint catch is compressed, thereby so that the taper steel-tooth that is positioned at inner side, joint body end is pushed into along the state radially opening of joint body and reaches the object of unclamping pipe.
Decontrol after 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 that is positioned at T-shape back-up ring, plate and the ring-type of joint body homonymy also can be arranged to integral type, thereby reduces the number of components of tube connection device, improves assembling speed.Same the T-shape back-up ring and the plectrum that are positioned at joint body homonymy, or be positioned at the T-shape back-up ring of joint body homonymy and the joint catch of ring-type all can be made of one formula.
