Description

Technical Field

[0001] The utility model belongs to the technical field of glasses, and particularly relates to an adjustable nose pad. Background Art

[0002] Glasses are used to improve eyesight, protect eyes or for decorative purposes. They usually include a frame and temple arms, and a nose pad is provided on the frame. The nose pad is a supporting structure for the glasses on the bridge of the nose. Except for most plate glasses, the nose pads installed on the existing frames usually include a lens leaf and a bracket.

[0003] If the wearer wants to wear comfortably, it is necessary to ensure that the lens leaf fits the wearer's bridge of the nose, and it is also necessary to ensure that the two lens leaves are located on opposite sides of the bridge of the nose. However, the nose shapes of different wearers are different, and the existing lens leaf and bracket are fixed one-to-one, and the bracket is fixed to the frame. The wearer cannot adjust the position of the lens leaf by himself. The non-adjustable nose pad is easy to press on the wearer's nose, and it is easy for the glasses to slide down frequently, bringing an uncomfortable wearing experience to the wearer. Summary of the Invention

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a nose pad with a better wearing experience than the prior art.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is: an adjustable nose pad, including a bracket and a lens leaf. The bracket includes a fixed end provided at the end. The lens leaf includes a front surface that fits the bridge of the nose and a back surface that fits the side wall of the fixed end. The front surface and the back surface are arranged back to back. A sliding cavity is provided on the surface of the fixed end facing the back surface. The lens leaf includes a sliding end that is embedded in the sliding cavity and can slide in the sliding cavity. At least two grooves are provided on one side wall of the sliding cavity parallel to the sliding direction of the sliding end, or at least two grooves are provided on both side walls of the sliding cavity parallel to the sliding direction of the sliding end. The grooves on the same side wall are arranged along the sliding direction of the sliding end. A convex portion that can form a limit with the groove is provided on the side wall of the sliding end facing the groove. An anti-disengagement structure is provided between the sliding end and the sliding cavity to prevent the sliding end from disengaging from the sliding cavity.

[0006] Adopting the above solution, when the position needs to be adjusted, applying a force to the lens leaf can make the sliding end slide along the sliding cavity. Through the cooperation of the groove and the convex portion, when the wearer wears the glasses, the lens leaf and the bracket remain relatively fixed. Through the cooperation of the sliding end and the sliding cavity, the position of the lens leaf can be adjusted, so that the utility model can adapt to more different nose shapes, is more comfortable to wear, and is more stable to wear at the same time.

[0007] As a further arrangement of the present utility model, the sliding cavity is a through cavity, and the anti - detachment structure includes an enlarged end provided on the sliding end. The enlarged end protrudes from the orifice of the sliding cavity away from the stipule, and a limit is formed between the enlarged end and the end face of the fixed end away from the stipule.

[0008] Adopting the above - mentioned scheme, the structure is simple, convenient for processing and assembly, and at the same time ensures the anti - detachment effect.

[0009] As a further arrangement of the present utility model, a deformation groove extending to the enlarged end is provided on the sliding end. The deformation groove is a through groove and is arranged longitudinally along the sliding direction of the sliding cavity.

[0010] Adopting the above - mentioned scheme, the existence of the deformation groove enables the enlarged end and the sliding end to have a certain deformation effect, which is convenient for the enlarged end to pass through the sliding cavity and at the same time convenient for adjusting the position of the stipule.

[0011] As a further arrangement of the present utility model, the surface of the enlarged end facing away from the deformation groove is an inclined surface, and the side of the inclined surface away from the stipule inclines towards the direction close to the deformation groove.

[0012] Adopting the above - mentioned scheme, it is convenient for the enlarged end to pass through the sliding cavity and at the same time ensures the anti - detachment effect.

[0013] As a further arrangement of the present utility model, the groove is an arc groove less than or equal to a semi - circle, and the surface of the convex part facing the groove is an arc surface; when the convex part is embedded in the groove, the convex part fits with the groove, or there is a gap between the convex part and the groove.

[0014] Adopting the above - mentioned scheme, it is convenient for the convex part to move to different grooves and convenient for adjusting the position of the stipule.

[0015] As a further arrangement of the present utility model, grooves are provided on both opposite cavity walls of the sliding cavity.

[0016] Adopting the above - mentioned scheme, when the wearer wears glasses, the stipule can better maintain relative fixation with the bracket.

[0017] As a further arrangement of the present utility model, there are two stipules and one bracket. The two stipules are fixed on the same bracket, and mounting holes are provided on the bracket.

[0018] Adopting the above - mentioned scheme, compared with the one - to - one fixation of the stipule and the bracket, fixing the two stipules on the same bracket enables the two stipules to be better located on the opposite sides of the bridge of the nose, providing a more comfortable wearing experience.

[0019] As a further arrangement of the present utility model, the mounting hole is one or two.

[0020] Adopting the above - mentioned scheme, it is adaptable to different spectacle frames.

[0029] The specific embodiments of the present utility model are as Figures 1-4 shown.

[0030] Embodiment 1: An adjustable nose pad, comprising a bracket 1 and a nose piece 2. The bracket 1 includes a fixed end 11 provided at the end. The nose piece 2 includes a front surface 21 that fits against the bridge of the nose and a back surface 22 that fits against the side wall of the fixed end 11. The front surface 21 and the back surface 22 are arranged in opposite directions. A sliding cavity 12 is provided on the surface of the fixed end 11 facing the back surface 22. The sliding cavity 12 is a through cavity. The nose piece 2 includes a sliding end 23 that is embedded in the sliding cavity 12 and can slide in the sliding cavity 12. A swelling end 24 that protrudes from the cavity opening of the sliding cavity 12 away from the nose piece 2 is provided on the sliding end 23. The swelling end 24 forms a limit with the end surface of the fixed end 11 away from the nose piece 2. In this embodiment, two grooves 121 are provided on both side walls of the sliding cavity 12 parallel to the sliding direction of the sliding end 23. The grooves 121 on the same side wall are arranged along the sliding direction of the sliding end 23. A convex portion 231 that can form a limit with the groove 121 is provided on the side wall of the sliding end 23 facing the groove 121.

[0031] When the position needs to be adjusted, applying a force to the nose piece 2 can make the sliding end 23 slide along the sliding cavity 12. Through the cooperation of the groove 121 and the convex portion 231, the nose piece 2 is kept relatively fixed with the bracket 1 when the wearer wears glasses. The existence of the swelling end 24 prevents the sliding end 23 from disengaging from the sliding groove. Through the cooperation of the sliding end 23 and the sliding cavity 12, the position of the nose piece 2 can be adjusted, so that the utility model can adapt to more different nose shapes, be more comfortable to wear, and be more stable to wear at the same time.

[0032] A deformation groove 25 extending to the swelling end 24 is provided on the sliding end 23. The deformation groove 25 is a through groove and is arranged through along the sliding direction of the sliding cavity 12. The existence of the deformation groove 25 enables the swelling end 24 and the sliding end 23 to have a certain deformation effect, which is convenient for the swelling end 24 to pass through the sliding cavity 12 and is also convenient for adjusting the position of the nose piece 2.

[0033] The surface of the swelling end 24 facing away from the deformation groove 25 is an inclined surface 241, and the side of the inclined surface 241 away from the nose piece 2 inclines towards the direction close to the deformation groove 25. This is convenient for the swelling end 24 to pass through the sliding cavity 12 and also ensures the anti-disengagement effect.

[0034] The groove 121 is an arc groove smaller than a semicircle, and the surface of the convex portion 231 facing the groove 121 is an arc surface; when the convex portion 231 is embedded in the groove 121, there is a gap between the convex portion 231 and the groove 121. This is convenient for the convex portion 231 to move to different grooves 121 and is convenient for adjusting the position of the nose piece 2.

[0035] Grooves 121 are provided on both opposite cavity walls of the sliding cavity 12, so that when the wearer wears glasses, the nose piece 2 can be better kept relatively fixed with the bracket 1.

[0036] There are two stipules 2 and one bracket 1. The two stipules 2 are respectively arranged at both ends of the bracket 1, and an installation hole 13 is provided in the middle of the bracket 1. Compared with the one-to-one fixation of the stipule 2 and the bracket 1, fixing the two stipules 2 on the same bracket 1 enables the two stipules 2 to be better located on the opposite sides of the nose bridge, providing a more comfortable wearing experience.

[0037] In this embodiment, there are two installation holes 13, enabling the bracket 1 to be fixed to the spectacle frame better and more stably.

[0038] Embodiment 2: The difference between Embodiment 2 and Embodiment 1 lies in the number and position of the installation holes 13. There is one installation hole 13 in this embodiment. Compared with Embodiment 1, the installation space required for the bracket 1 in this embodiment is smaller. Embodiment 2 and Embodiment 1 can be adapted to different styles of spectacle frames.

[0039] The present utility model is not limited to the above specific embodiments. Those of ordinary skill in the art can implement the present utility model in other various specific embodiments according to the content disclosed in the present utility model, or any simple changes or modifications made by adopting the design structure and concept of the present utility model fall within the protection scope of the present utility model.
