Nose clamping glasses
The utility model relates to the technical field of glasses, more specifically say, it relates to a pince-nez formula glasses.
Glasses have become common articles in modern life, and besides various functional purposes, the glasses also become ornaments for people. Traditional glasses are including the picture frame that has two lens installation frame circles to and install the mirror leg on the picture frame, two lens installation frame circles of picture frame are connected through the nose bridge frame, are equipped with the nose on the nose bridge frame and hold in the palm. When the clothes are worn, the clothes have larger load bearing feeling and are too common, and the individual requirements of people cannot be met. In order to reduce the load feeling, the glasses with no glasses legs and nose clamping type come into being, and the glasses are mainly fixedly worn by utilizing two clamping pieces on a nose bridge frame to oppositely clamp and fix the two clamping pieces on the nose bridge. Because the clamping piece passes through the mutual centre gripping of the power of spring and fixes, can be to the very big clamp force of the different very big of growing of human nose bridge, the longer the time of wearing, the nose bridge position is impaired easily, wears the travelling comfort poor, serious can influence healthy.

The embodiments of the pince-nez of the present invention will be further described with reference to fig. 1 to 4.
A pair of pince-nez type glasses comprises a lens assembly 1 and a nose support assembly 2, wherein the nose support assembly 2 comprises a beam frame 20 and two nose support leaves 21 which are matched with each other in a corresponding manner, mounting arms 22 are connected to the nose support leaves 21 in a one-to-one manner, the mounting arms 22 are rotatably arranged to drive the two nose support leaves 21 to open and close each other, connecting arms 23 for mounting the nose support leaves 21 and operating arms 24 for driving the two nose support leaves 21 to open are connected to the mounting arms 22, the holding ends of the operating arms 24 are positioned at the outer side of the lens assembly 1, springs 25 for driving the two nose support leaves 21 to close are arranged on the two mounting arms 22, round holes 220 are arranged on the mounting arms 22, an adjusting shaft 26 is arranged between the two round holes 220 in a penetrating manner, limit blocks 260 are respectively arranged at the two ends of the adjusting shaft 26 after the round holes 220 are arranged in a penetrating manner, two positioning rings 261 are arranged on the adjusting shaft 26 in a, the end face of the positioning ring 261 close to the mounting arm 22 is provided with a buffering ring sheet 262, and an elastic member 263 is arranged between the buffering ring sheet 262 and the positioning ring 261.
When the nose pad is worn, the operating arms 24 are held by fingers, the elastic force of the springs 25 is overcome, the two nose pad blades 21 are opened, the two operating arms 24 are released, and under the action of the elastic force of the springs 25, the two nose pad blades 21 clamp the bridge of the nose of a human body to be worn preliminarily. Then, the distance between the two positioning rings 261 is expanded by rotating the positioning rings 261 on the adjusting rod, and the distance between the two nose pad blades 21 is expanded, so that the clamping force of the two nose pad blades 21 on the nose bridge is moderate, and the comfort is kept. Be equipped with buffering ring piece 262 on holding ring 261, it is scalable that the buffering reed passes through elastic component 263, after the position has been adjusted to holding ring 261, elastic component 263 is scalable, makes buffering ring piece 262 be close to holding ring 261, plays the effect that the fine setting reduces the interval between two installation arms 22, can the fine setting simultaneously two interval between the nose holds in the palm the leaf 21, keeps the fastness of wearing.
The nose pad blade 21 is provided with a pad 210, the pad 210 is provided with a fluted disc 211, the nose pad blade 21 is provided with an assembling groove 212 for the fluted disc 211 to be installed, and the groove wall of the assembling groove 212 is provided with a plurality of convex strips 213 which are in friction fit with the teeth on the fluted disc 211. The other end face of the supporting sheet 210, which is provided with the fluted disc 211 relatively, is provided with a rubber cushion cover 214, and a rubber band penetrates through the opening of the rubber cushion cover 214.
Fluted disc 211's setting, can realize the angular adjustment of lens subassembly 1, the fixed centre gripping of support piece 210 is on the human bridge of the nose, when the angle of lens is not good, can upwards push away or pull down the angle of adjusting the lens, at the in-process of adjustment, assembly groove 212 is along fluted disc 211 circumferential direction, the latch of fluted disc 211 and the sand grip 213 friction fit in the assembly groove 212, make lens subassembly 1 adjust to suitable angle after, can establish the effect through the card of fluted disc 211 and sand grip 213, with the fixed angle of lens subassembly 1. The cover is equipped with rubber cushion cover 214 on support piece 210, can promote the travelling comfort of wearing, and rubber cushion cover 214 can be dismantled through the running-on of rubber band simultaneously, the convenient change. Soft materials such as cotton can be filled between the rubber cushion cover 214 and the supporting sheet 210, so that the wearing comfort is improved.
