Abstract
The utility model discloses a fast pipe connector for a compound pipe, comprising a connector main body with screw-thread external threads, an upper shell, a clasping ring with a section, a lower shell, a C-shaped ring of a reverse clasping pipe cylindrical surface and a sealing member, wherein the sealing member is arranged on a circumferential groove positioned on the connector main body; one end of the upper shell is connected with the connector main body, and the other end is connected with the lower shell; the clasping ring is arranged in a cavity formed by the connector main body, the upper shell and the lower shell; one end of the clasping ring, which is far away from the lower shell, is internally provided with a support ring resisting the clasping force of the clasping ring; the outer diameter of the support ring is larger than the inner diameter of the clasping ring; and the outer side of the support ring is also provided with a cavity containing the support ring. The utility model has the advantages of convenient installation, high connection reliability, difficult water leakage and easy subsequent maintenance and is suitable for the connection of pipes and pipe fittings.
Description
Technical field
The utility model relates to pipe joint, particularly relates to the quick pipe joint of a kind of composite pipe.
Background technique
At present, plastic tube or plastic-metal composite pipe generally adopt the mechanical type pipe joint, but this pipe joint ubiquity is installed inconvenience, and the defective of later maintenance difficulty is easily leaked in long-term use.(patent No.: 00132958.8) though solved the problems referred to above, but still exist can not reusable problem when mistake occurring when installing for Chinese patent " pipe joint ".
Summary of the invention
The purpose of this utility model is in order to overcome the deficiency of above-mentioned background technology, to provide a kind of easy for installation, connection reliability height, the quick pipe joint of the simple composite pipe of antileaking and later maintenance.
In order to realize above purpose, the quick pipe joint of a kind of composite pipe that the utility model provides, comprise: the adapter body of threaded outer screw thread, upper shell, the hold-fast ring of band section, lower shell body, oppositely hold the C type ring and the Sealing that is installed on circumferential groove on the adapter body of tubing cylndrical surface tightly, upper shell one end links to each other with adapter body, the other end links to each other with lower shell body, hold-fast ring is arranged in adapter body, in the cavity that upper shell and lower shell body form, be provided with the resistance hold-fast ring in the end of described hold-fast ring away from lower shell body and hold the support ring of power tightly, the external diameter of this support ring is bigger than the internal diameter of hold-fast ring, and the outside of support ring also is provided with the cavity that holds support ring.
In such scheme, described support ring external diameter is provided with support rim, and position corresponding on the skewed slot of hold-fast ring has the groove that matches with support rim.
In such scheme, described section is an oblique section.
The utility model adopts the structure add external diameter support ring littler than hold-fast ring internal diameter in hold-fast ring to solve the problem that the mechanical type pipe joint is installed inconvenience; Simultaneously hold-fast ring has the bigger power of holding tightly, like this, when support ring be ejected break away from cavity after, encircle and tightly encircle tight pipe fitting, make the Sealing that is provided with in the circumferential groove on pipe fitting and the adapter body external diameter closely contact, form and seal, thus antileaking; And adapter body adopts and to be threaded, and is convenient to dismounting, is easy to change Sealing, solved the problem of later maintenance difficulty.
The utility model is compared with the prior art, and shows that fully its superiority is: easy for installation, and the connection reliability height, antileaking and later maintenance are simple etc.

Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail, but this embodiment should not be construed as restriction of the present utility model.
Present embodiment provides a kind of composite pipe quick pipe joint, comprise: the adapter body 1 of threaded outer screw thread, upper shell 2, the hold-fast ring 4 of band oblique section, lower shell body 5, oppositely hold the C type ring 6 and the Sealing 7 that is installed on circumferential groove on the adapter body of tubing cylndrical surface tightly, upper shell 2 one ends link to each other with adapter body 1, the other end links to each other with lower shell body 5, hold-fast ring 4 is arranged in adapter body 1, in the cavity that upper shell 2 and lower shell body 5 form, be provided with resistance hold-fast ring 4 in the end of described hold-fast ring 4 away from lower shell body 5 and hold the support ring 3 of power tightly, the external diameter of this support ring 3 is bigger than the internal diameter of hold-fast ring 4, and the outside of support ring 3 also is provided with the cavity 8 that holds support ring 3.Described support ring 3 external diameters are provided with support rim 3.1, and position corresponding on the skewed slot 4.1 of hold-fast ring 4 has the groove that matches with support rim 3.1.
Whether whether above-mentioned upper shell 2 and lower shell body 5 all adopt transparent resin, like this, be easy to observe support ring 3 and break away from from hold-fast ring 4, can discern tubing, pipe fitting from the outside and connect and put in place.
In order to have stopped the generation of potential corrosion phenomenon, plastics processing is also passed through on support ring 3 surfaces in the present embodiment.
During the utility model work, only need pipe fitting is inserted in the hold-fast ring 4, until pipe fitting support ring 3 is ejected hold-fast ring 4 and get final product.Support ring 3 from hold-fast ring 4, break away from fall cavity 8 after, hold-fast ring 4 is held pipe fitting tightly, and is compressed pipe fitting because elasticity is shunk at once, and pipe fitting closely contact with Sealing 7, formation seals.
