Description

Technical Field

[0001] The utility model relates to the technical field of glasses legs, in particular to a foldable glasses leg. Background Art

[0002] Glasses are mainly composed of lenses, frames, temples, etc. Wearing glasses can protect the eyes or correct vision.

[0003] After searching, the application with patent number 202021658742.0 discloses a foldable glasses leg of a new and improved structure, including a first leg and a second leg, wherein a fixing groove is provided at one end of the first leg close to the second leg, both sides of the fixing groove are opened, a rotating shaft is provided in the fixing groove, grooves are provided on the top inner wall and the bottom inner wall of the fixing groove, and both ends of the rotating shaft extend into the corresponding grooves respectively, a connecting plate is fixedly installed at one end of the second leg close to the first leg, an end of the connecting plate away from the second leg extends into the fixing groove and is fixedly connected to one side of the rotating shaft, and an arc-shaped card groove is provided on the side of the rotating shaft away from the connecting plate;

[0004] Although the foldable glasses legs of the new improved structure are convenient for folding the first leg and the second leg for easy storage and carrying, the second leg of the foldable glasses legs of the new improved structure is easily bent toward the outside of the fixing groove, which may easily cause the glasses to fall off when worn.

[0005] Therefore, we propose a folding temple. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a foldable glasses leg, which solves the problem that the second leg of the prior device is easily bent toward the outside of the fixing groove, which easily causes the glasses to fall off when worn.

[0007] To achieve the above purpose, the utility model is implemented by the following technical solutions: a folding eyeglass leg, comprising a front leg, an L-shaped leg is arranged on the right side of the front leg, and an extended leg is arranged on the right side of the L-shaped leg;

[0008] The front leg comprises an integrally formed connection portion and an oblique L portion, and a groove portion is formed through the side surface of the oblique L portion;

[0009] The bending part of the L-shaped leg is slidably mounted inside the groove part, and a shaft rod is fixedly mounted on the bending part of the L-shaped leg. Both ends of the shaft rod are rotatably mounted on the side wall of the groove part through bearing rings, and an oblique L-shaped spring sheet is fixedly installed on the outer side wall of the L-shaped leg. The end of the oblique L-shaped spring sheet away from the L-shaped leg is in contact with the side wall of the connecting part.

[0010] Preferably, after the L-shaped leg rotates 45° about the shaft rod, the end of the inclined L portion contacts the side wall of the inclined L-shaped spring sheet, wherein during the process of the L-shaped leg rotating 45° about the shaft rod, the end of the inclined L portion does not contact the inclined L-shaped spring sheet.

[0011] Preferably, during the process of the L-shaped leg rotating 45° to 135° around the shaft rod, the end of the inclined L portion is always in contact with the side wall of the inclined L-shaped spring sheet, wherein, during the process of the L-shaped leg rotating 45° to 135° around the shaft rod, the inclined L portion is in contact with the side of the inclined L-shaped spring sheet, so that the inclined L-shaped spring sheet can bend and generate elastic force, when the L-shaped leg rotates 45° to 90° around the shaft rod, the elastic force generated by the inclined L-shaped spring sheet can make the L-shaped leg move outward, and when the L-shaped leg rotates 90° to 135° around the shaft rod, the elastic force generated by the inclined L-shaped spring sheet can make the L-shaped leg move inward.

[0012] Preferably, after the L-shaped leg rotates 180° about the shaft rod, the inclined L-shaped spring sheet is parallel to the inclined L portion, wherein, during the process of the L-shaped leg rotating 135° to 180° about the shaft rod, the inclined L portion does not contact the inclined L portion, and after the L-shaped leg rotates 180° about the shaft rod, the L-shaped leg is clamped inside the groove portion.

[0013] Preferably, a slide groove with the same specifications as the L-shaped leg is provided on the left side of the extended leg, and one end of the L-shaped leg away from the shaft rod is movably sleeved inside the slide groove, wherein the groove portion can be hung on the ear.

[0014] Preferably, a first threaded hole distributed in a linear array is formed on the side wall of the L-shaped leg away from one end of the inclined L-shaped spring sheet, and a second threaded hole opposite to the first threaded hole and connected to the slide groove is formed on the side wall of the extended leg, and the internal threads of the first threaded hole and the second threaded hole are sleeved with bolts, wherein the extended leg is pulled toward the side away from the L-shaped leg, and the second threaded hole is aligned with the first threaded hole, and then the bolt is threadedly sleeved inside the second threaded hole and the first threaded hole, so as to facilitate adjustment of the overall length of the extended leg and the L-shaped leg to accommodate wearers with different head sizes.

[0015] The utility model provides a foldable glasses leg, which has the following beneficial effects:

[0016] 1. The foldable glasses leg supports the L-shaped leg through the wearer's head to prevent the L-shaped leg from bending inward, and supports the L-shaped leg through the oblique L-shaped spring sheet to prevent the L-shaped leg from bending outward, thereby preventing the L-shaped leg from bending outward easily and causing the glasses to fall off the wearer's head. When the L-shaped leg and the front leg need to be stored, the L-shaped leg is bent inward, and then the L-shaped leg is rotated inwardly with the shaft as the axis, and finally the L-shaped leg is clamped in the inside of the groove portion, so that the L-shaped leg and the front leg can be folded together, which is beneficial to reducing the space occupied by the front leg and the L-shaped leg, making it easy to store them, and solving the problem that the second leg of the existing device is easy to bend to the outside of the fixing groove, which easily causes the glasses to fall off when worn;

[0017] 2. The foldable glasses leg is configured to be able to accommodate wearers with different head sizes by pulling the extended leg to the side away from the L-shaped leg, aligning the second threaded hole with the first threaded hole, and then threading the bolt into the second threaded hole and the first threaded hole, thereby facilitating adjustment of the overall length of the extended leg and the L-shaped leg. The foldable glasses leg has a wide range of applications. BRIEF DESCRIPTION OF THE DRAWINGS
