It is susceptible between spring shell and U-shaped spring core depart from.
Summary of the invention:
The present invention be directed to above deficiency, it is provided that bar location leg of spectacles in a kind of twin-core, the present invention provides a kind of tradition bullet
Property temple, it is a kind of design with revolutionary improvement, relies on concavo-convex position to position spring core, substantially increases the essence of catapult
Degree, service life.Wherein, including the limited block design preventing spring core from deviating from, concavo-convex position and location bar design etc..
The technical solution adopted for the present invention to solve the technical problems is:
A kind of New positioning mechanism leg of spectacles, including leg of spectacles and pile crown, described pile crown is fixed with hinge seat, described
Hinge seat is hinged with U-shaped spring core by bearing pin, is provided with die cavity in described spring case, and described U-shaped spring core part is positioned at
In die cavity, die cavity oral area be provided with one restriction spring stretch limited block, on described U-shaped spring core with in the die cavity of spring case
It is equipped with the concavo-convex position worked in coordination；Spring is positioned at spring core；Time static, spring core is concavo-convex with coordinate in spring case
Stroke cavity it is provided with between Wei；During motion, concavo-convex position offsets.
Being additionally provided with gag lever post in described spring case, be provided with U-shaped chamber in described U-shaped spring core, described gag lever post is positioned at U
Shape intracavity, and when static, there is certain interval in gag lever post and U-shaped chamber.
Being additionally provided with the groove for placing spring on described spring case, described groove is semi-circular groove, and half circular diameter
More than spring diameter of section.
Described spring core is provided with arc surface with the end face place of cooperation of spring case or hypotenuse is excessive.
Described pile crown welds with hinge seat, thermal or assembly connection.
Described spring core lower end is provided with foot, and described foot is slidably matched with leg of spectacles.
The method have the benefit that 1. spring cores of the present invention do not have in spring case rock, the problem such as abjection；2.
Invention designs inner position mechanism, and it is more accurate to position.

Detailed description of the invention:
Embodiment 1: as shown in figures 1-8, a kind of detent mechanism leg of spectacles, including leg of spectacles 8 and pile crown 7, described pile crown 7
On be fixed with hinge seat 6, described hinge seat 6 is hinged with U-shaped spring core 1 by bearing pin, is provided with die cavity in described spring case 2,
Described U-shaped spring core 1 part is positioned at die cavity, and die cavity oral area is provided with and limits the limited block 4 that spring 3 stretches, described U-shaped bullet
Being equipped with, with in the die cavity of spring case 2, the concavo-convex position worked in coordination on spring fuse 1, spring core is provided with convex position 1.1, spring case
It is provided with recess 2.1；Spring 3 is positioned at spring core 1；Time static, the concavo-convex position coordinated in spring core 1 and spring case 2 it
Between be provided with stroke cavity；During motion, concavo-convex position offsets.The design of stroke can effectively prevent spring core from deviating from.
Being additionally provided with the groove for placing spring 3 on described spring case 2, described groove is semi-circular groove, and semicircle is straight
Footpath is more than spring 3 diameter of section.This design is more stable firm in spring can be made to install spring case.
Described spring core 1 is provided with arc surface with the end face place of cooperation of spring case 2 or hypotenuse is excessive.This design makes
Spring core is not easy to damage.
