Abstract

The utility model discloses a decorative chain, comprising a plurality of chain links end to end which are made by twisting oval rings and are in central symmetry. The oval rings are twisted upward and downward via two axles in plus and minus thirty degrees to sixty degrees with the long axes of the ovals. The decorative chain has the advantages of generous appearance and saving materials.

Description

Join chain

Technical field

The utility model relates to ornaments, is specifically related to a kind of chain of joining.

Background technology

Join chain and have a wide range of applications in daily life, the chain of joining in the prior art all more or less exists moulding not attractive in appearance, and the higher shortcoming of consumptive material.

The utility model content

The purpose of this utility model is, a kind of chain of joining of handsome in appearance and economical with materials is provided.

The technical scheme that the utility model provides is as follows: construct a kind of chain of joining, comprise the chain link that some head and the tail connect, described chain link is by vesica piscis distortion and the structure of making and be centrosymmetric, described distortion mode be achieved in that by become with transverse ± two axles of 30-60 degree make progress, twist this elliptical ring respectively downwards.

Described two axles become with described transverse respectively ± 30 degree.

The protuberance of the upper ring surface of the described vesica piscis that is twisted and following anchor ring has the point of contact of two cross section ovalizes respectively.

The utlity model has following advantage: chain link is the structure of making and be centrosymmetric by the vesica piscis distortion, good looking appearance; The protuberance of the upper ring surface of the vesica piscis that is twisted and following anchor ring has the point of contact of two cross section ovalizes, economical with materials respectively.

The specific embodiment

With reference to Fig. 1, Fig. 2, a kind of chain of joining is provided, comprise the chain link 1 that some head and the tail connect, chain link 1 is the structure of making and be centrosymmetric by the vesica piscis distortion, the distortion mode be achieved in that by become with transverse ± 30 the degree two axles make progress, twist this elliptical ring respectively downwards, certainly, this angle also can be selected between 30 to 60 degree, and vesica piscis just is twisted into the twisted shape structure.

The protuberance of the upper ring surface of the vesica piscis that is twisted and following anchor ring has the point of contact 2 of two cross section ovalizes respectively, so not only attractive in appearance but also saving material.

Claims (3)

1, a kind of chain of joining, comprise the chain link that some head and the tail connect, it is characterized in that described chain link is by vesica piscis distortion and the structure of making and be centrosymmetric, described distortion mode be achieved in that by become with transverse ± two axles of 30-60 degree make progress, twist this elliptical ring respectively downwards.

2, the chain of joining according to claim 1 is characterized in that, described two axles become with described transverse respectively ± 30 degree.

3, the chain of joining according to claim 1 is characterized in that, the protuberance of the upper ring surface of the described vesica piscis that is twisted and following anchor ring has the point of contact of two cross section ovalizes respectively.
