Description

Technical Field

[0001] The utility model relates to a pair of glasses, in particular to an optical glasses. Background Art

[0002] Glasses are lens pieces embedded in the temples and worn in front of the eyes to improve eyesight, protect the eyes or for decorative purposes. Glasses can correct various vision problems, including myopia, hyperopia, astigmatism, presbyopia or strabismus, etc. There are various types of glasses, including optical glasses, contact lenses and protective glasses, etc.

[0003] Glasses are mainly supported on the human head through the nose pads and temple arms. The existing nose pad materials on the market are mainly divided into three types: metal, plastic and rubber; for nose pads of different materials, there are various different advantages in actual use. Among them, the rubber nose pad is deeply loved by wearers because its elastic material can play a good buffering role in the weight of the glasses during wearing, and in addition, it has excellent anti-slip effect. However, because the rubber material has good lipophilicity, the anti-slip effect of the rubber nose pad will be greatly reduced after long-term contact with the oil on the skin of oily wearers, which will cause sliding during wearing and ultimately affect the wearing stability. Therefore, if a nose pad made of rubber material is selected, the nose pad needs to be replaced regularly. The existing nose pads are fixed to the nose bridge through bolts, and special operating tools are required to disassemble them. In addition, if the sharp head of the screwdriver is accidentally deflected during rotation, it is very easy to scratch the lens and cause unnecessary damage to the glasses. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an optical glasses, and the nose pad of the optical glasses can be disassembled more conveniently and will not cause damage to the glasses.

[0005] The above technical purpose of the utility model is realized through the following technical solutions: an optical glasses, including a frame, a nose pad, and lenses and a nose bridge provided on the frame. An installation groove for installing the support arm of the nose pad is formed on the nose bridge. The optical glasses further include a fixing pin. A first fixing hole communicating with the installation groove is provided on the nose bridge. A second fixing hole is provided on the support arm of the nose pad, and when the nose pad is installed in the installation groove, the first fixing hole and the second fixing hole are coaxially communicated. The fixing pin is inserted into the first fixing hole and the second fixing hole to limit the nose pad from detaching from the installation groove. A dial block exposed to the outside is movably arranged on the nose bridge. A locking component for restricting the fixing pin from moving along the axis of the first fixing hole is provided on the nose bridge. The dial block is connected to the locking component for controlling the locking component to switch between a locking position and a non-locking position.

[0006] By adopting the above technical solution, when the nose pad is to be replaced, the locking assembly is switched from the locked position to the unlocked position by toggling the toggle block, and the fixing pin can be pulled out from the first fixing hole and the second fixing hole, thereby separating the nose pad from the nose bracket and replacing the nose pad. This replacement method does not require special operating tools and will not cause damage to the glasses, making the removal and replacement of the nose pad more convenient.

[0007] It is further configured as follows: the locking assembly is arranged inside the nose bracket, and the shifting block is slidably arranged on the nose bracket and at least partially located outside.

[0008] By adopting the above technical solution, this setting structure can protect the locking component while maintaining the simplicity of the original appearance of the glasses to the greatest extent, thereby ensuring consumers' purchasing desire and the aesthetics of the glasses.

[0009] It is further configured that: a part of the shifting block located at the outside is provided with a shifting hole.

[0010] By adopting the above technical solution, the setting of the dial hole can easily control the movement of the dial block by inserting a toothpick into the dial hole without causing damage to the glasses, thereby further improving the convenience of operation.

[0011] It is further configured that: the locking assembly includes a locking plate located on one side of the orthogonal projection of the first fixing hole and reciprocating toward the first fixing hole, an elastic member for positioning the locking plate to maintain it in a locked position, and a locking groove arranged on the fixing pin corresponding to the movement path of the locking plate.

[0012] By adopting the above technical solution, the elastic member is used to locate the position of the locking piece. When the locking piece is inserted into the locking slot, the fixing pin can be locked, and the unlocking operation can be achieved when the locking piece leaves the locking slot.

[0013] It is further configured that: the locking groove is arranged on the outer peripheral wall of the fixing pin and is distributed around the outer peripheral wall to form a ring shape.

[0014] By adopting the above technical solution, the locking function can be easily achieved by inserting the fixing pin, making the operation more convenient.

[0015] It is further configured that: the insertion end of the fixing pin is provided with a guide portion for pushing the locking plate away from the first fixing hole and moving the locking plate to the side away from the first fixing hole.

[0016] By adopting the above technical solution, the guide portion is provided so that when the fixing pin is inserted into the first fixing hole, it can automatically push off the locking plate and then pass through the locking plate to complete the insertion operation, making the operation more convenient.

[0017] Further configured as: It further includes temple arms connected to the spectacle frame. An elastic strip is provided at the position where the temple arms contact the contour of the ear root. A plurality of connecting parts passing through the temple arms are fixedly connected to the elastic strip, and a limiting strip for restricting the elastic strip from detaching from the temple arms is inserted through the connecting parts.

[0018] By adopting the above technical solution, the elastic strip is provided to achieve anti-slip between the temple arms and the contour of the ear root and reduce the pressure sensation during wearing, thereby improving the comfort and stability of wearing. Pulling out the limiting strip can achieve separation from the connecting part, and then realize the replacement of the elastic strip.

[0019] Further configured as: The limiting strip is embedded in the temple arm. A magnetic attraction structure is provided between one end of the limiting strip and the temple arm, and the other end extends to the outside.

[0020] By adopting the above technical solution, the magnetic attraction structure is used to achieve detachable fixation between the limiting strip and the temple arm.

[0021] In summary, the present utility model has the following beneficial effects: The nose pad of the present utility model is more convenient to disassemble and will not cause damage to the glasses. BRIEF DESCRIPTION OF THE DRAWINGS
