The purpose of this utility model is defect for prior art and deficiency, provides a kind of joint for plastic tube, and adopt technology of withholding to connect, safer, application area is wider.
For achieving the above object, the utility model is by the following technical solutions:
A kind of joint for plastic tube, comprise adapter body, Sealing, link and move back pipe cap, the inwall of adapter body is provided with draw-in groove, link is provided with the projection fastened with draw-in groove, Sealing and link are sequentially installed in adapter body, and the draw-in groove on the projection of link and adapter body inwall fastens, move back pipe cap and abut with Sealing through link.
Wherein, described draw-in groove is be arranged on the annular slot on adapter body inwall, and described projection is for being arranged on the annular protrusion on link outer wall.
Preferably, the inwall of described link is provided with position limiting convex ring, described in move back pipe cap outer end be provided with the boss coordinated with this position limiting convex ring.Described inner end of moving back pipe cap is provided with elastic clamping hook.
Preferably, described Sealing is O type circle.
The utility model beneficial effect is compared with prior art:
Joint for plastic tube of the present utility model is for adopting fastened structure, directly by link press-in connector main body during connection, the projection on link is made to be embedded in the draw-in groove of adapter body, realization is fastenedly connected, compared with existing ultrasonic welding mode, assembling is simpler, better tightness, connect safer, application area of the present utility model is wider.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In Fig. 1:
1. adapter body, 2. Sealing, 3. link, 4. move back pipe cap, 5. draw-in groove, 6. protruding.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, a kind of joint for plastic tube, comprises adapter body 1, Sealing 2, link 3 and moves back pipe cap 4, and described Sealing 2 is O type circle.The inwall of adapter body 1 is provided with draw-in groove 5, described draw-in groove 5 is for being arranged on the annular slot on adapter body 1 inwall, link 3 is provided with the projection 6 fastened with draw-in groove 5, described protruding 6 for being arranged on the annular protrusion on link 3 outer wall, Sealing 2 and link 3 are sequentially installed in adapter body 1, and the projection 6 of link 3 fastens with the draw-in groove 5 on adapter body 1 inwall, move back pipe cap 4 and abut with Sealing 2 through link 3.Preferably, the inwall of described link 3 is provided with position limiting convex ring, described in move back pipe cap 4 outer end be provided with the boss coordinated with this position limiting convex ring.Described inner end of moving back pipe cap 4 is provided with elastic clamping hook.
This pipe joint is for adopting fastened structure, directly by link 3 press-in connector main body 1 during connection, the projection 6 on link 3 is made to be embedded in the draw-in groove 5 of adapter body 1, realization is fastenedly connected, compared with existing ultrasonic welding mode, assembling is simpler, better tightness, and link 3 material is no longer confined to plastic material, thus its application area is wider.
The above, it is only preferred embodiment of the present utility model, not any restriction is made to technical scope of the present utility model, therefore every above embodiment is done according to technical spirit of the present utility model any trickle amendment, equivalent variations and modification, all still belong in the scope of the technical solution of the utility model.
