Description
Technical field
The present invention relates to pipe fitting mounting technique field, refer in particular to a kind of plastic-aluminum combined effective direct insertion joint.
Background technology
At present, joint for aluminium-plastic composite tube frequently be pincers-pressed type and nut bite type structure.Wherein, pincers-pressed type joint
Need to be installed with special pressing tongs, be wasted time and energy, and if installing space ratio is narrow, also cannot complete to install, in addition, such as
Pincers-pressed type joint is not pressed onto position by fruit installation personnel imprudence, also can cause to leak, furthermore, if pincers-pressed type joint is let out
Leakage, can not be dismantled it is necessary to cut off tubing, maintenance cost height, joint nor recycling.And nut bite type connects
Head need to be installed with spanner tightening nut, more wastes time and energy, and also has space to limit, if installing space ratio is narrow,
Cannot complete install, joint does not have observation port, if tubing is not inserted into position, and or installation personnel does not tighten, just have
After risk of leakage, and use a period of time, nut is susceptible to loosen, and also has risk of leakage.
Content of the invention
The invention provides a kind of plastic-aluminum combined effective direct insertion joint, this plastic-aluminum combined effective direct insertion joint does not need
Instrument can complete to install, time saving and energy saving, and does not have space to limit, good seal performance.
For reaching above-mentioned purpose, the technical solution adopted in the present invention is：
A kind of plastic-aluminum combined effective direct insertion joint, includings hollow and one end is provided with the joint body of nozzle belt, is taking over

Pipe box 1, is provided with the first inclined-plane 41 on the end covering 2 adjacent power-assisted seats 4 with clamp, in the clamp set in the first latch 26 outside
2 inwalls are provided with the second inclined-plane 25 with the first inclined-plane 41 cooperation, take one end of pipe box 1 to be located in casing 3, the other end extends
To outside casing 3.During insertion tubing 8, the first inclined-plane 41 is coordinated with the second inclined-plane 25, under the guide effect on the first inclined-plane 41,
Clamp set 2 opens, and facilitates tubing 8 to insert；When taking tubing 8, only pipe box 1 need to will be taken to push away inward, take pipe box 1 can promote clamp set
2 move to power-assisted seat 4 direction, and under the guide effect on the first inclined-plane 41, clamp set 2 opens, and tubing 8 just can easily be extracted.
One end inner surface stretching in casing 3 on pipe box 1 is taken to form barb 11, setting on casing 3 takes pipe box 1
It is provided with the hook and slot 33 matching with barb 11 in one end, take pipe box 1 to be connected to shell by the cooperation of barb 11 and hook and slot 33
On set 3.
Seal groove 62 Sidewall Height near joint body 6 side is more than the Sidewall Height of opposite side.This structure is along pipe
Pressure medium direction design in road, sealing property is more preferable.
Outer shell base 5 outer wall is provided with annular slot 51, the annular with draw-in groove 62 cooperation is provided with the inwall of casing 3
Fin 32.This structure is simply firm.
Sidewall Height away from the draw-in groove 51 of casing 3 side is more than the Sidewall Height of relative opposite side, and this side
Side wall is connected for arc with draw-in groove 51 bottom.Improve the intensity of outer shell base 5 so that resistance to the drawing of the entirety of the present invention dials performance significantly
Improve.
Clamp set 2 is provided with the circular hole 23 communicating with opening blind slot 22 root.Improve the elastic force of clamp set 2.
Above-listed detailed description is illustrating for one of present invention possible embodiments, and this embodiment simultaneously is not used to limit
The scope of the claims of the present invention, all equivalence enforcements done without departing from the present invention or change, are intended to be limited solely by the scope of the claims of this case
