Abstract

The utility model discloses a jump ring, including the jump ring body, the jump ring body is circular -arcly, and it has the arch to extend to the inboard at the both ends of jump ring body, is equipped with the handle hole in the arch, and interference fit has the metal lining in the handle hole, and the metal lining is the I shape, and central department is equipped with the through -hole at the metal lining. The utility model discloses an interference fit metal lining in jump ring's handle hole has prevented that the jump ring pincers directly are used for the masterpiece two walls of handle hole, has improved jump ring's life greatly, and can not drop, compares with sticky, and is more firm.

Description

A kind of jump ring

Technical field

The utility model relates to a kind of jump ring, belongs to fastener areas.

Background technique

In the axial trough that jump ring is mainly used in machinery or hole slot, play a part the part axial motion stoped on axle or on hole.When installing, dismantling, usually through Circlip tongs, the handle hole of masterpiece on jump ring is come.And due to inside, Circlip tongs update hole point sharper, often can damage handle hole, after repeatedly installing, dismantling, handle hole is easily damaged, thus make the installation again of jump ring, dismounting becomes very inconvenient.

Chinese utility model patent Authorization Notice No. CN203161759U discloses a kind of jump ring, by arranging rubber gasket in handle hole, installing, dismounting jump ring time, Circlip tongs can not directly and handle hole contact internal walls, therefore, handle hole can not be damaged, after repeatedly installing, dismantling, only need to change rubber gasket, because rubber gasket is connected through fixing glue with the inwall of handle hole, therefore, its replacing is also very convenient.But this patented technology is when practical application, but there is such problem: because jump ring body is very thin, make handle hole inwall also very thin, rubber gasket, when being bondd by fixing glue with handle hole inwall, is not only difficult to cement, even and if clung when Workshop Production, during use, under Circlip tongs active force, be also easy to come off, lose the effect of protection jump ring handle hole.

Model utility content

For solving the problems of the technologies described above, the utility model provides a kind of jump ring, can be damaged in fence operation hole well, improve working life, and can not come off by after Circlip tongs multi-pass operation.

For achieving the above object, the technical solution of the utility model is: a kind of jump ring, comprise jump ring body, jump ring body is arc-shaped, be extended with projection in the inward at both ends side of jump ring body, projection is provided with handle hole, and in handle hole, interference fit has metal lining, metal lining is I shape, is provided with through hole in metal lining center.

The utility model, by interference fit metal lining in the handle hole of jump ring, prevents Circlip tongs directly masterpiece to be used for two walls of handle hole, substantially increases the working life of jump ring, and can not come off, compared with gluing, more firmly.
