Abstract
The utility model relates to a hose of hose and other disposition of equipments, especially an inlay hose of packing ring are woven to the hot -water heating, and it contains hose main part, spiral shell parent interface, connects core and seal ring, its characterized in that is in be equipped with a plurality of racks on seal ring's the outside, seal ring sets up on spiral shell parent interface's the inner bottom, the up end top of rack is in on spiral shell parent interface's the ridge. Its purpose can be installed seal ring in spiral shell parent interface in order to design one kind, and the inlay hose of packing ring who is difficult for falling out. Compared with the prior art, having easy to assemblely and the transportation, reducing the packing volume, reduce the labor employment number, seal ring is difficult for losing, and the seal ring atress is even, advantages such as long service life.
Description
Technical field
The utility model relates to the flexible pipe of hot-water heating flexible hose and other equipment use, particularly a kind of flexible pipe being embedded with packing ring.
Background technique
Flexible pipe is a kind of connection pipe fitting connecting main water outlet, oily port and water inlet, oily port, flexible pipe is generally made up of hose main body, nut interface, fuse and seal washer, wherein seal washer is as a kind of sealed member, each nut interface requires configuration seal washer, the cross-sectional structure of existing seal washer is toroidal structure, all want after seal washer and nut interface match to pack separately separately, seal washer is easily lost in transportation process, installs and transport inconvenience.
Summary of the invention
The purpose of this utility model seal washer can be arranged in nut interface to design one, and the flexible pipe being embedded with packing ring not easily dropped out.
In order to achieve the above object, the utility model adopts following technical solution: a kind of flexible pipe being embedded with packing ring, comprise hose main body, nut interface, connect fuse and seal washer, it is characterized in that on the outside of described seal washer, be provided with some tooth bars, described seal washer is arranged at the interior end of described nut interface, and the upper-end surface of described tooth bar withstands on the worm tooth of described nut interface.
The utility model, in order to improve seal washer lower end surface uniform stressed, prevents seal washer to be out of shape, and improves seal washer working life, arranges further: be provided with seal washer locating face in described seal washer lower end surface to described technological scheme.
The utility model installs embedding to further facilitate packing ring, not easily drop out again simultaneously, described technological scheme is arranged further: the points outside of described tooth bar and the distance in the described seal washer center of circle are greater than described nut interface internal thread standard path, and are less than the large footpath of described nut interface outside thread standard.
The utility model compared with prior art, the beneficial effect had:
1, reduce Packing Unit, reduce labor number.
2, convenient installation and transport.
3, seal washer is not easily lost.
4, seal washer uniform force, long service life.
Accompanying drawing explanation
Fig. 1 is the present embodiment structural representation.
Fig. 2 is gasket structure principal section figure in the present embodiment.
Fig. 3 is the plan view of Fig. 2.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, Figure 2, Figure 3 shows, the present embodiment comprises hose main body 4, nut interface 1, connects fuse 3 and seal washer 2, the outside of described seal washer 2 is provided with some tooth bars 5, the points outside of described tooth bar 5 and the distance in described seal washer 2 center of circle are greater than described nut interface 1 internal thread standard path, and are less than the large footpath of described nut interface 1 outside thread standard.Described seal washer 2 is arranged at the interior end of described nut interface 1, and the upper-end surface of described tooth bar 5 withstands on the worm tooth of described nut interface 1.
In addition, seal washer 2 be connected fuse 3 screw cooperation time, part conjunction plane is had to be in the state of not stressing outside seal washer 2 lower end surface, therefore, in order to improve seal washer 2 lower end surface uniform stressed, prevent seal washer to be out of shape, improve seal washer working life, be provided with seal washer locating face 6 (shown in Fig. 2) in described seal washer 2 lower end surface.
