Abstract

The utility model discloses a screw cap, including plastics screw cap body, be provided with the screw thread on the hole of plastics screw cap body, the axial upper end of hole is equipped with the radial inside fender shoulder that extends, the cladding has metal casing on the outer peripheral face of plastics screw cap body. Through adopting above -mentioned structure, because plastics screw cap body is made by plastics, therefore its hole can not take place to rust, and the cladding has metal casing on the outer peripheral face of plastics screw cap body, then can make its surface have metallic luster concurrently. Simultaneously, because of the utility model provides a screw cap is by plastics screw cap body and metal casing is compound constitutes, consequently compares prior art and is formed by the integrative die -casting of all -metal, and its manufacturing cost can reduce by a wide margin.

Description

A kind of nut

Technical field

This utility model relates to a kind of connector, is specifically related to a kind of nut。

Background technology

At present, the first-class inlet and outlet pipe of the sanitaryware such as fire hose is all connected by braided tube, described braided tube is provided with nut, but existing nut is all-metal integrated die-casting and forms, so not only production cost is higher, and the endoporus of nut is also easy to get rusty because of long-term Inlet and outlet water, thus what affect tap water drinks quality。

Summary of the invention

For the deficiencies in the prior art, this utility model provides a kind of novel nut, and it not only can be greatly reduced production cost, and its endoporus will not get rusty, and its outer surface has metallic luster concurrently simultaneously。

For achieving the above object, this utility model provides a kind of nut, includes plastic cap nut body, the endoporus of plastic cap nut body is provided with screw thread, the axially end of described endoporus is provided with the shoulder block extended radially inwardly, and the outer peripheral face of described plastic cap nut body is coated with metal shell。

The beneficial effects of the utility model are: adopting said structure, owing to plastic cap nut body is made of plastics, therefore its endoporus will not get rusty, and is coated with metal shell on the outer peripheral face of described plastic cap nut body, then its outer surface can be made to have metallic luster concurrently。, because nut provided by the utility model is to be made up of plastic cap nut body and metal shell compound, therefore being formed by all-metal integrated die-casting compared to existing technology, its production cost can be greatly reduced meanwhile。

This utility model can be further arranged to the axially end face of described plastic cap nut body and be provided with the upper bulge loop extended axially upward, the lower axial end face of described plastic cap nut body is provided with the lower convex ring extended radially outwardly, and described upper bulge loop and lower convex ring all with the female coaxial heart, the upper end of described metal shell is correspondingly sleeved on described upper bulge loop, and the lower end of described metal shell is resisted against on described lower convex ring。By above-mentioned setting, metal shell can be made to be firmly fixed on the outer peripheral face being positioned at plastic cap nut body。

This utility model may further be provided as described upper bulge loop all identical with the thickness of metal shell with the thickness of lower convex ring。By above-mentioned setting, the overall outer surface of nut can be made to seem neat appearance more。

Detailed description of the invention

Give a kind of nut as shown in Figure 1, 2, include plastic cap nut body 1, the endoporus 11 of plastic cap nut body 1 is provided with screw thread 12, the axially end of described endoporus 11 is provided with the shoulder block 13 extended radially inwardly, setting by described shoulder block 13, nut can be easy to and be connected fixing with braided tube formation, the outer peripheral face of described plastic cap nut body 1 is coated with metal shell 2。The axially end face of described plastic cap nut body 1 is provided with the upper bulge loop 14 extended axially upward, the lower axial end face of described plastic cap nut body 1 is provided with the lower convex ring 15 extended radially outwardly, and described upper bulge loop 14 and lower convex ring 15 all with endoporus 11 concentric, the upper end of described metal shell 2 is correspondingly sleeved on described upper bulge loop 14, and the lower end of described metal shell 2 is resisted against on described lower convex ring 15。Described upper bulge loop 14 is all identical with the thickness of metal shell 2 with the thickness of lower convex ring 15。

By adopting said structure, owing to plastic cap nut body 1 is made of plastics, therefore its endoporus 11 will not get rusty, and is coated with metal shell 2 on the outer peripheral face of described plastic cap nut body 1, then its outer surface can be made to have metallic luster concurrently。, because nut provided by the utility model is to be made up of plastic cap nut body 1 and metal shell 2 compound, therefore being formed by all-metal integrated die-casting compared to existing technology, its production cost can be greatly reduced meanwhile。
