Abstract
The utility model relates to a fast pipe joint which is designed for sealing well. The utility model comprises a pipe joint body, and an insertion part inserted into a soft pipe is arranged on the end part of the pipe joint body. The utility model is characterized in that the surface of the insertion part is provided with a plurality of annular racks, and a tightening element is sheathed outside, wherein the tightening element is divided into two cavities which are semicircle-shaped plastic elements, and the plastic elements are connected and fixed by screws. The utility model has the advantages of simple structure, and good tightness, and is not easy to loose, so the utility model is suitable for popularization and application in pipe joints.
Description
The utility model relates to a kind of quick coupling technical field.
Along with living standards of the people improve constantly, people also require more and more high to living environment, usually near residential district, villa, beautify the environment in the planting gardens, the flowers and trees gardens will people often water water, in the pouring process, people often will use flexible tube, the first-class parts of quick pipe connecting, realize that flexible tube is connected fast with hard tube.It as the patent No. 94217457.7 Chinese patent " quick coupling ", it comprises a fittings body, two C shape packing rings and tightening nut, the joint end has the insertion portion in an outside thread and the insertion flexible tube, the insertion portion outer surface has some annular grooves, and being equipped with in the annular groove has a tightening nut in addition, when screwing tightening nut, pipe can be coupled together fast.Its shortcoming: parts are many, processed complex, and cost of production height, and when using often drags under the carrying situation when pipe especially, and nut is easily loosening, causes sealing bad, easily leakage liquid.
The purpose of this utility model is to provide a kind of simple in structure, good seal performance, is difficult for loosening quick coupling.
The technical solution of the utility model is to realize like this.This quick coupling, it includes union body, there is insertion portion in the flexible tube of insertion the union body end, it is characterized in that described insertion portion surface has many annular racks, and fastening piece of overcoat, it is semicircle working of plastics that fastening piece is divided into two inner chambers, is connected and fixed with screw between the working of plastics.
Above-mentioned working of plastics internal surface has annular shallow slot at insertion portion outer surface annular rack position.
Quick coupling of the present utility model adopts fastening piece and annular rack cooperating structure, after inserting insertion portion, tightly fixes flexible tube with fastening piece, latch is goed deep in the flexible tube surface, so good seal performance, and be difficult for becoming flexible, when being in, flexible tube often drags under the towing situation, also can keep good coupled condition, simple in structure, parts are few, be convenient to manufacturing, suit on flexible tube connects, to apply.
Description of drawings:
Fig. 1. quick pipe connecting header structure one complete section figure;
Fig. 2. quick pipe connecting header structure two complete section figure;
Fig. 3. quick pipe connecting header structure three complete section figure;
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
Embodiment's 1. these quick couplings include union body 1, there is insertion portion 3 in the flexible tube of insertion at the union body two end part, 2-3 bar annular rack 4 is opened on the insertion portion surface, and fastening piece of overcoat, it is semicircle working of plastics 10 that fastening piece is divided into two inner chambers, both sides are opened screw 5 usefulness screws and are connected and fixed between the working of plastics, and the working of plastics internal surface has annular shallow slot 2 at insertion portion outer surface annular rack position.This quick coupling is suitable for connecting fast flexible tube.
Embodiment's 2. these quick coupling body 1 one ends are shaped on outside thread 6, the other end such as embodiment's 1 new structure, and it is suitable for flexible tube and is connected fast with hard tube.
Embodiment's 3. these quick coupling body 1 one end card inserted types are fixed with a nut 8, are shaped on internal thread 7 in the nut, and lining seal washer 9, the other end such as embodiment's 1 new structure.It is suitable for flexible tube and is connected fast with hard tube.
