Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As glasses embodiment with rotatable nose holds in palm, as shown in fig. 1 to 4, hold in the palm 3 including picture frame 1, well roof beam 2 and nose, picture frame 1 and 2 fixed connection of well roof beam, the whole shape of well roof beam 2 is the arc, the middle part shape that the nose held in the palm 3 is the arc, the both ends of well roof beam 2 all are equipped with first gear 4, and two medial surfaces that two first gear 4 are relative are equipped with chrysanthemum tooth 41, the nose holds in the palm 3 both ends and all is equipped with second gear 5, and two lateral surfaces that two second gear 5 are relative also are equipped with chrysanthemum tooth 51, the both ends card that the nose held in the palm 3 is established at well roof beam 2 both ends, and two first gear 4 and two second gear 5 mesh respectively.

The glasses with the rotatable nose pads are completely new in design for the middle beam 2 and the nose pads 3, the whole shape of the middle beam 2 is designed to be arc-shaped, two ends of the nose pads 3 are clamped at two ends of the middle beam 2 and can rotate around the two ends of the nose pads, and because the middle parts of the nose pads 3 are arc-shaped, when the nose pads 3 rotate around the two ends of the nose pads at different positions, the angles of the nose pads are changed, so that a person wearing the glasses can obtain different visual angles; in addition, both ends of the middle beam 2 are provided with first gears 4, both ends of the nose support 3 are provided with second gears 5, matching surfaces of the first gears 4 and the second gears 5 are provided with chrysanthemum teeth 41 and 51 which can be meshed with each other, and the first gears 4 and the second gears 5 can not rotate relatively after being meshed, so that the positions of the nose support 3 and the middle beam 2 are relatively fixed; when the angle of the nose pad needs to be adjusted, the middle beam 2 or the nose pad 3 is slightly deformed by force until the first gear 4 and the second gear 5 are not meshed any more, the nose pad 3 can be taken down at the moment, or the nose pad is directly rotated to a proper angle, and then the middle beam 2 or the nose pad 3 is loosened, so that the first gear 4 and the second gear 5 are meshed again, and the positions of the nose pad 3 and the middle beam 2 are relatively fixed again, thereby the whole process of adjusting the angle of the nose pad is completed, the operation can be easily completed manually without tools, the adjustment can be repeatedly carried out, the parts are not easy to wear and damage, a person wearing the glasses can adjust the angle of the nose pad at any time and any place without any trouble, so as to ensure normal posture, and the problems of the person wearing the glasses can be well solved.

In this embodiment, the middle of the inner side surface of the first gear 4 is further provided with a positioning hole 42, the middle of the outer side surface of the second gear 5 is further provided with a positioning column 52 (the positioning column here can be integrally formed with the nose support, or integrally formed with the second gear, which is the former embodiment), and after the first gear 4 and the second gear 5 are engaged, the positioning column 52 is inserted into the positioning hole 42, so that the nose support 3 is not easily separated from the middle beam 2 during angle adjustment, so that a person wearing the glasses can concentrate on angle adjustment, and the design is more humanized.

In this embodiment, the indexing angle of the daisy teeth 41 and 51 on the first gear 4 and the second gear 5 is at least 30 degrees, and the smaller the indexing is, the finer the adjustment of the angle of the nose pad is, but the more the number of the daisy teeth is, the more difficult the processing is, the less the depth of the daisy teeth is, and the direct effect on the meshing strength is, so the depth of the daisy teeth should be greater than 1 mm.

In the present embodiment, the first gear 4 and the center sill 2 are made of metal materials, and the first gear 4 is fixed on the center sill 2 by welding. Because the centre sill 2 is metal material, and the rigidity is great, so make centre sill 2 produce enough deformation and probably need great tension, in order to solve this problem, the material of nose support 3 is Polyetherimide (PEI), and second gear 5 is fixed on nose support 3 through the equipment, and the polyetherimide material has fine elasticity and toughness, is particularly useful for making the utility model discloses a nose support. Naturally, the two ends of the center sill are thinned, and the reduction of the rigidity of the center sill is a good solution.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
