[0006] By adopting the above technical solution, when the user needs to adjust the distance between the glasses frame and the eyes, the user can rotate the glasses frame to drive the shaft sleeve to adjust the glasses frame to flip upward and move away from the eyes without taking off the glasses. This is extremely convenient, has good adaptability, and is simple in structure.

[0007] The above technical solution is further configured as follows: a first serration is provided on an end surface of one end of the sleeve along the circumferential direction, a second serration is provided on a side wall of the limiting groove, the first serration and the second serration can engage with each other, and a spacing not less than the tooth height of the first serration is provided between the other end of the sleeve and the other side wall of the limiting groove; a spring is provided on the pin shaft, the spring is provided at an end away from the first serration on the sleeve, and the spring has an elastic tendency to bring the first serration and the second serration closer together.

[0008] By adopting the above technical solution, the first sawtooth slides relative to the second sawtooth and the sleeve compresses the spring, the first sawtooth is completely separated from the second sawtooth, the sleeve rotates one tooth pitch, and the eyeglass frame sleeve continues to rotate multiple tooth pitches. The eyeglass frame deflects upward by a certain angle, so that the eyeglass frame is flipped upward and positioned away from the eyes. The elasticity of the spring achieves an automatic positioning effect, and it will not loosen or swing, which is extremely convenient.

[0009] The above technical solution is further configured as follows: the tooth shapes of the first sawtooth and the second sawtooth are in a wavy and smooth transition.

[0010] By adopting the above technical solution, the shaft sleeve is easy to rotate and will not be stuck.

[0011] The above technical solution is further configured as follows: a transition fit is formed between the pin and the sleeve.

[0012] The above technical solution is further configured as follows: the mounting block is connected to the crossbeam by screws.

[0013] By adopting the technical solution, installation and disassembly are facilitated.

[0014] The beneficial effect achieved by the utility model is that when the user needs to adjust the distance between the glasses frame and the eyes, the user can rotate the glasses frame to drive the shaft sleeve to adjust the glasses frame to flip upward and position away from the eyes without taking off the glasses, which is extremely convenient, has good adaptability and simple structure.

[0015] The first sawtooth slides relative to the second sawtooth to compress the spring of the sleeve, the first sawtooth completely disengages from the second sawtooth, the sleeve rotates one tooth pitch, and the eyeglass frame sleeve continues to rotate multiple tooth pitches, and the eyeglass frame deflects upward by a certain angle, so that the eyeglass frame is flipped upward and positioned away from the eyes without loosening or swinging.

[0024] like Figure 1 to Figure 5 As shown, a pair of glasses with an adjustable eyeglass frame and automatic positioning comprises an eyeglass frame 2, a frame edge 1 and a nose pad 3. A crossbeam 4 is provided in the middle of the frame edge 1, and temples are connected to the two sides of the frame edge 1. A mounting block 5 is connected to the crossbeam 4, one side of the mounting block 5 is connected to the nose pad 3, and the other side of the mounting block 5 is provided with a U-shaped limiting groove 51, a pin shaft 6 is provided at the opening of the limiting groove 51, a shaft sleeve 7 is provided on the pin shaft 6, a side wall of the shaft sleeve 7 is connected to the eyeglass frame 2, the shaft sleeve 7 can rotate relative to the pin shaft 6 and can be positioned, and there is a transition fit between the pin shaft 6 and the shaft sleeve 7. When the user needs to adjust the distance between the eyeglass frame 2 and the eyes, the user can rotate the eyeglass frame 2 to drive the shaft sleeve 7 to rotate on the pin shaft 6, thereby adjusting the eyeglass frame 2 to flip upward and position away from the eyes. The system is extremely convenient, has good adaptability and a simple structure.

[0025] One end face of the sleeve 7 is provided with a first serration 71 along the circumferential direction, and a second serration 511 is provided on one side wall of the limiting groove 51, the first serration 71 and the second serration 511 can mesh with each other, and a spacing 8 which is not less than the tooth height of the first serration 71 is provided between the other end of the sleeve 7 and the other side wall of the limiting groove 51; a spring 9 is provided on the pin shaft 6, and the spring 9 is arranged at an end away from the first serration 71 on the sleeve 7, and the spring 9 has an elastic tendency to bring the first serration 71 and the second serration 511 closer to each other, and the first serration 71 slides relative to the second serration 511 to compress the sleeve spring 9, and the first serration 71 completely disengages from the second serration 511, and the sleeve 7 rotates one tooth pitch, and the sleeve of the eyeglass frame 2 continues to rotate to rotate multiple tooth pitches, and the eyeglass frame 2 deflects upward by a certain angle, so that the eyeglass frame is flipped upward and positioned away from the eyes, and the elasticity of the spring achieves an automatic positioning effect, and it will not loosen or swing, and there is no need to remove the glasses, which is extremely convenient. And unlike the hinge structure on the market, the glasses frame can still be flipped and automatically positioned after long-term use and multiple adjustments, and will never slide down.

[0026] The tooth shapes of the first saw teeth 7 and the second saw teeth 511 are in a wave-like and smooth transition, so the shaft sleeve is easy to rotate and will not be stuck.

[0027] The mounting block 5 is connected to the crossbeam 4 by screws 10, which is convenient for installation and disassembly.

[0028] When the user needs to adjust the distance between the eyeglass frame 2 and the eyes, the eyeglass frame 2 is rotated to drive the sleeve 7 to rotate on the pin 6, the first serration 71 slides relative to the second serration 511 to compress the spring 9, the first serration 71 is completely disengaged from the second serration 511, the sleeve 7 rotates one or more tooth pitches to make the eyeglass frame 2 flip upward away from the eyes, and when the sleeve 7 stops rotating, the elasticity of the spring 9 makes the first serration 71 fit the second serration 511 to position the eyeglass frame.
