Description

Technical Field

[0001] The utility model relates to the technical field of glasses, in particular to a U-shaped spring-type structure for adjusting the length of glasses legs. Background Art

[0002] Glasses have become a necessity in many people's daily lives, but they are easy to slip off during exercise, so glasses with bendable temples have emerged. To achieve the best effect of bendable temples, the length of the temples must be adjusted to the most appropriate position. In addition, for children in the growth stage, the length of the temples of their glasses also needs to be adjusted as they age.

[0003] At present, the market uses a clamp-type structure to adjust the length of the glasses legs. There are one-piece types and separate workpiece types. Both require professional tools and training to operate. In addition, the one-piece type is easy to break because the workpiece is too small, and the separate type is easy to fall off because the workpiece is too small, making the adjustment process too complicated, time-consuming and laborious. Therefore, a U-shaped spring-type structure for adjusting the length of the glasses legs is proposed to solve the above problems. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a U-shaped spring-type structure for adjusting the length of the eyeglass legs. When the length of the eyeglass legs is adjusted, the principle of the U-shaped spring is used to make the product components have corresponding elasticity without any auxiliary structure, thereby generating stable elastic force. The upper and lower clamping points are designed to stabilize the product components in specified positions, and the recessed position on one side of the hole position of the component corresponding to the clamping point is convenient for fingers to press the U-shaped spring component, thereby achieving the advantages of easy adjustment and greater convenience. This solves the problem that the length of the eyeglass legs in the current market is adjusted by using a clamping structure, which has a one-piece type and a separate workpiece type, both of which require professional tools and training to operate, and the one-piece type is prone to breakage due to the small workpiece, and the separate type is prone to fall off due to the small workpiece, making the adjustment process too complicated, time-consuming and labor-intensive.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a U-shaped spring-type structure for adjusting the length of eyeglass legs, comprising a frame, wherein the frame is internally movably connected with a temple, and the outer surface of the temple is detachably connected with an extension leg, and an extension adjustment structure is provided between the temple and the extension leg;

[0006] The extension adjustment structure includes a U-shaped spring piece, which is fixedly connected to the outer surface of the temple. The top and bottom of the U-shaped spring piece are fixedly connected with a snap-on protrusion. A square mounting hole is provided inside the extension leg, and an extrusion through hole is provided at the top and bottom of the extension leg.

[0007] Furthermore, a nose pad is arranged on the front of the frame, a screw is passed through the side of the frame opposite to the temple, and the temple is hinged to the frame through the screw.

[0008] Furthermore, the U-shaped spring piece is located inside the extension leg through the square mounting hole, and the two clamping protrusions are clamped with the extension leg through the extrusion through hole.

[0009] Furthermore, the number of the extruded through holes is determined according to actual needs, and are symmetrically distributed inside the extension leg in groups of two.

[0010] Furthermore, a pressing recess is provided on the side of the extrusion through hole.

[0011] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0012] The U-shaped spring-type structure for adjusting the length of the eyeglass legs is used, when the frame 1 is worn on the bridge of the nose, it is contracted by pressing the U-shaped spring piece 7 according to the requirements of use, and then inserted into the inside of the square mounting hole 6 inside the extension leg 5, and then the snap-on protrusion 6 is snapped into the inside of the pressing through hole 9. When the length needs to be extended, the snap-on protrusion 8 is squeezed to disengage it from the inside of the pressing through hole 9, and then it is adjusted to the required length, thereby achieving the purpose of easy adjustment without the aid of any tools during the length adjustment process, and simple and convenient operation.
