Abstract

The invention discloses a necklace lobster clasp, and relates to the ornament accessories field. The original lobster clasps are manufactured by casting soft alloys. The soft alloys are replaced by a hard zinc alloy to avoid the environmental pollution caused by the alloying element lead. Hard materials are not suitable for a die made of a soft material, and a casting can not be drawn from the die. Therefore, the structure of the necklace lobster clasp is characterized in that an internal wall of a shell is provided with a bulge axle head, an axle hole is arranged on the external surface of an internal clasp, an external side face of the axle hole is provided with a convex ring surrounding the axle hole, a spring groove is provided around the convex ring, a return spring is arranged on the convex ring, one pin of the return spring is propped against the side face of the spring groove, and the other pin is propped against the internal side face of the shell. The necklace lobster clasp has the beneficial effects of simple structure, convenient casting and being incapable of getting struck by the die.

Description

Necklace langouste buckle

Technical field

The present invention relates to daily necessities field, especially the ornaments annex.

Background technology

Jewelry is the articles for use that people often wear, generally be worn on the neck for chain jewelry, on the wrist or on the ankle, in order to wear conveniently, langouste buckle all is equipped with in termination at jewelry, the other end is a clamping ring, langouste buckle is by shell, interior button and return spring are formed, and have the necklace connecting hole in the shell upper end, in shell upper two medial surface corresponding positions, the axle hole that respectively has depression, in the interior corresponding position, axle hole of buckling on portion's two lateral surfaces, have the spindle nose of protrusion, around spindle nose, have groove, equipped by spindle nose with the axle hole, shell with in link and be connected together, return spring is sleeved on the spindle nose with groove one side, a pin of spring withstands on the shell inner side edge, the side of button groove in the another pin withstands on, when wearing, only need compression retracteding position spring that the normally closed port of shell and interior button is opened, the clamping ring of the other end is penetrated, unclamp return spring again, return spring reinstatement normally closed port is closed, and chain jewelry just firmly connects.The langouste buckle that uses is to be formed by soft alloy casting at present, contains lead in the alloy, pollutes the environment, because the consumption of necklace langouste buckle is very big, so see that apparent size is very little, the contaminant capacity that causes is not little.So change soft alloy into quality harder kirsite gradually at present.This has just brought the new problem in the casting, buckle the spindle nose that two sides have outside protrusion interior as mentioned above, because when in casting, detaining, be that the interior button that casting is good is extracted out from mould, this is unchallenged for soft alloy, but just become problem for carbide alloy,, it can successfully have been taken out from mould so must change the structure of necklace langouste buckle.

Summary of the invention

Purpose of the present invention is for providing a kind of simple in structure, and casting is convenient, not a kind of necklace langouste buckle that can be blocked by mould.

The technical scheme that realizes above-mentioned purpose is as follows:

Necklace langouste buckle, form by shell, interior button and return spring, has the necklace connecting hole in the shell upper end, the spindle nose that respectively has protrusion in the corresponding position of shell upper two sides, buckle portion and the spindle nose corresponding position has axis hole interior, spindle nose and axis hole activity are assembled together, make shell and interior button form one, has bulge loop at a lateral surface of axis hole around axis hole, around bulge loop, have spring groove, be set with return spring on bulge loop, a pin of return spring withstands on the spring groove side, and the another pin withstands on the inner side edge of shell.

Technique scheme changes the original outstanding spindle nose in interior button surface into axis hole, has guaranteed to be provided with on interior button surface the part of protrusion, the problem that interior button can not be extracted out from mould when having solved casting.

The present invention has simple in structure, and casting is convenient, can not blocked by mould, helps the material beneficial effect of carbide alloy as part.
