Problems solved by technology

[0002] At present, elastic glasses legs on the market have been widely used, but there are still many deficiencies: traditional elastic glasses legs have low precision due to design and process defects, large connection swings, and easy to fall out during use. There are many problems such as easy to break off, and there is a problem of low precision between the spring shell and the U-shaped spring core, which is prone to separation between the spring shell and the U-shaped spring core.

Embodiment 1

[0021] Embodiment 1: as Figure 1-8 As shown, a positioning mechanism spectacle leg includes a spectacle leg 8 and a pile head 7. A hinge seat 6 is fixed on the pile head 7, and the hinge seat 6 is hinged with a U-shaped spring core 1 through a pin shaft. The spring shell 2 is provided with a mold cavity, and the U-shaped spring core 1 is partly located in the mold cavity. There are concave and convex positions that cooperate with each other in the cavity of the spring shell 2. The spring core is provided with a convex position 1.1, and the spring shell is provided with a concave position 2.1; the spring 3 is located in the spring core 1; when it is at rest, the spring core There is a stroke cavity between the concave and convex positions matched in the sub 1 and the spring shell 2; when moving, the concave and convex positions are offset. The stroke design can effectively prevent the spring core from coming out.

[0022] The spring shell 2 is also provided with a groove for...

Embodiment 2

[0025] Embodiment 2: The difference between embodiment 2 and embodiment 1 is that the U-shaped spring core 1 is provided with a concave position 2.1, and the spring shell 2 is provided with a convex position 1.1, and the concave position 2.1 cooperates with the convex position 1.1.

Embodiment 3

[0026] Embodiment 3: The difference between embodiment 3 and embodiment 1 is that a limit rod 9 is also provided in the spring shell 2, a U-shaped cavity is arranged in the U-shaped spring core 1, and the limit rod is located at In the U-shaped cavity, and at rest, there is a certain gap between the limit rod and the U-shaped cavity. This design enables the spring core to have a certain stroke in the spring case. Compared with Embodiment 1, this double stroke limit can effectively prevent the spring core from coming out and positioning.

Abstract

The invention relates to a novel positioning mechanism glasses leg comprising a glasses leg body and a pile head. A hinge base is fixed to the pile head and hinged to a U-shaped spring core through a pin shaft, a cavity is arranged in a spring shell, the U-shaped spring core is partially located in the cavity, the opening of the cavity is provided with a limit block for limiting stretching of a spring, and concaves and convexes fitting with each other are arranged on the U-shaped spring core and in the cavity the spring shell; the spring is located in the spring core; not in motion, stroke cavities are arranged between the concaves and the convexes fitting with each other in the spring core and the spring; in motion, concaves and the convexes abut against each other. A limit rod is further arranged in the spring shell. A semicircular groove for holding the spring is further arranged in the spring shell, and the diameter of the semicircle is larger than that of the section of the spring. The novel positioning mechanism glasses leg has the advantages that the spring core in the spring shell cannot shake, fall out and the like; mounting and dismounting are facilitated.

Description

Technical field: [0001] The invention belongs to the technical field of glasses manufacturing, and relates to an elastic eyeglass leg and an elastic pin. Background technique: [0002] At present, elastic glasses legs on the market have been widely used, but there are still many deficiencies: traditional elastic glasses legs have low precision due to design and process defects, large connection swings, and easy to fall out during use. There are many problems such as easy to break away from the child, and there is a problem of low precision between the spring shell and the U-shaped spring core, and it is easy to break away between the spring shell and the U-shaped spring core. Invention content: [0003] The present invention aims at the above deficiencies, and provides a double-core inner rod positioning spectacle leg. The present invention provides a traditional elastic spectacle leg, which is a design with revolutionary improvement. The accuracy of the slingshot, the se...
