Summary of the invention
The utility model is intended to address the above problem, and a kind of simple in structure, easy to operate connection assembly for pipes is provided.Reach the purpose of this utility model by following measure:
This connection assembly for pipes, it is characterized in that, it is made of connector main body, sleeve and nut, wherein, jacket casing is located at the connecting end outside of the tubing that is connected, connector main body one end is placed through in the sleeve, and is connected by its outside thread and tubing, and nut sleeve is loaded on the other end of connector main body.
Sleeve diameter and tube outer diameter are suitable, and the one end is provided with uncovered, and the other end is provided with annular endplate, are provided with seal ring between annular endplate and pipe end.
Connector main body comprises tubing joint and nut joint, the tubing joint is provided with outside thread and at least one seal groove, seal groove is located at the front end of this one, seal ring is housed in the seal groove, nut joint external diameter is greater than the tubing joint and form first convex shoulder, the nut joint also is provided with external diameter and is used for the second spacing convex shoulder of nut greater than first convex shoulder, nut joint end is provided with boss vertically, seal ring is housed on the boss, for the enhanced leaktightness effect, seal groove and seal ring can be two groups.
The endoporus of nut joint and standard inner hexagon spanner are complementary, and are used to realize that the engage thread of connector main body and tubing is connected.
It is simple in structure using the advantage of the utility model connection assembly for pipes, not high to the material requirements of assembly, loads and unloads simple and conveniently, and can repeatedly use, and the most important thing is the obturation effect that can reach good.
Description of drawings
Fig. 1 is the structure sectional view that the utility model is connected with tubing.
Fig. 2 is the knot sectional view of connector main body.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the sectional view of the utility model connection assembly for pipes and tubing coupled condition, and the tubing in the present embodiment is the compound aluminum pipes of plastics, and this tubing 20 is made of trilaminate material, and the centre is an aluminum pipe 21, inside and outside layer 22 composite plastic; Connection part 10 is made of sleeve 11, connector main body 12 and nut 13, sleeve 11 is sheathed on the connecting end outside of the tubing 20 that is connected, sleeve 11 internal diameters are suitable with tubing 20 external diameters, the one end be provided with to turn up uncovered 111, be beneficial to tubing 20 and pierce into, the other end is provided with annular endplate 112, and the aperture of annular endplate 112 is not less than the aperture of tubing 20, be used to insert connector main body 12, and between the annular endplate 112 of sleeve pipe 11 and pipe end, be provided with seal ring 113; Simultaneously referring to Fig. 2, connector main body 12 is the links that connect, comprise tubing joint and nut joint, the tubing joint is provided with outside thread 121 and is placed through in the sleeve 11 and with tubing 20 and is connected, consider seal, be provided with seal groove 122 at tubing joint front end, seal ring 123 is housed in the seal groove 122, seal groove 122 and seal ring 123 have two groups in the present embodiment, install for convenience, the external diameter of the end 124 of connector main body is less than tubing 20 internal diameters, nut joint external diameter is greater than the tubing joint and form first convex shoulder 125, the nut joint also is provided with external diameter and is used for the second spacing convex shoulder 126 of nut greater than first convex shoulder 125, nut 13 packs into from the tubing joint and is stuck on second convex shoulder 126, nut joint end is provided with boss 127 vertically, and seal ring 128 is housed on the boss 127, purpose be with such as the water halter, the parts of threeway and so on seal when connecting; Connector main body 12 realizes that with being connected by engage thread of tubing 20 in the present embodiment, the endoporus 129 and the standard inner hexagon spanner of nut joint are complementary, and by spanner connector main body 12 are installed in the tubing 20.
