[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1: Please refer to Figure 1-6 The utility model provides a technical solution: a pair of lens protection glasses, comprising a frame 1, two lenses 2 are arranged on the frame 1, first temples 3 are rotatably mounted on both sides of the frame 1, an adjustment structure is arranged on the first temple 3, a second temple 4 is mounted on the adjustment structure, two storage grooves 7 are provided on the frame 1, a U-shaped frame 8 is rotatably mounted in the storage groove 7 through a rotating shaft, the U-shaped frame 8 is adapted to the lenses 2, a shifting block 10 is mounted on the U-shaped frame 8, two positioning structures are mounted on the frame 1, and the two positioning structures are respectively in contact with the two U-shaped frames 8. When the glasses are not in use, the U-shaped frame 8 can be pulled out of the storage groove 7 by using the shifting block 10, and the U-shaped frame 8 is rotated until it is perpendicular to the lenses 2. Therefore, when the glasses accidentally fall to the ground, the U-shaped frame 8 can block the front of the lenses 2 to protect the lenses 2 and prevent the lenses 2 from directly contacting the ground and causing damage.

[0025] The positioning structure includes two fixed blocks 5, which are mounted on the mirror frame 1. The two fixed blocks 5 are rotatably mounted with inclined blocks 51, which are in contact with the U-shaped frame 8. The inclined blocks 51 are provided with rotation holes 53. The two fixed blocks 5 are mounted with retaining shafts 52, which are rotatably mounted in the rotation holes 53. The retaining shafts 52 are sleeved with torsion springs 54, one end of which is mounted on the retaining shafts 52, and the other end of which is mounted in the rotation holes 53. When the U-shaped frame 8 is rotated to be perpendicular to the lens 2, the U-shaped frame 8 contacts the inclined surface of the inclined block 51, driving the inclined block 51 to gradually rotate upward, causing the torsion spring 54 inside it to deform. When the U-shaped frame 8 is rotated to be completely perpendicular to the lens 2, the U-shaped frame 8 is no longer in contact with the inclined block 51, and the inclined block 51 will rotate back to its original position under the rebound action of the torsion spring 54, blocking the top of the storage groove 7, preventing the U-shaped frame 8 from rotating back into the storage groove 7 and losing its protective effect on the lens 2.

[0026] Furthermore, two rubber pads 9 are installed on the U-shaped frame 8, and the rubber pads 9 are in contact with the inner wall of the storage groove 7. When using the glasses, the U-shaped frame 8 is rotated and retracted into the storage groove 7. By utilizing the friction between the rubber pads 9 and the storage groove 7, the U-shaped frame 8 will not be easily rotated out of the storage groove 7. The U-shaped frame 8 is stored in the storage groove 7, making the glasses more beautiful and simple.

[0027] The working principle is as follows: when the glasses are not in use, the U-shaped frame 8 can be pulled out of the storage groove 7 by using the pull block 10, and the U-shaped frame 8 is rotated until it is perpendicular to the lens 2. In the process of rotating the U-shaped frame 8, the U-shaped frame 8 contacts the inclined surface of the inclined block 51, driving the inclined block 51 to gradually rotate upward, so that the torsion spring 54 inside it is deformed. When the U-shaped frame 8 is rotated to be completely perpendicular to the lens 2, the U-shaped frame 8 does not contact the inclined block 51, and the inclined block 51 will rotate back to its original position under the rebound action of the torsion spring 54, blocking the top of the storage groove 7, blocking the U-shaped frame 8, and preventing the U-shaped frame 8 from rotating back into the storage groove 7. Therefore, when the glasses accidentally fall to the ground, the U-shaped frame 8 can block the front of the lens 2, protect the lens 2, and prevent the lens 2 from directly contacting the ground and causing damage.

[0028] Embodiment 2: The adjustment structure includes a rotating knob 6, one side of the rotating knob 6 is rotatably mounted on the first temple 3, a threaded rod 61 is threadedly mounted on the rotating knob 6, a movable groove 62 is provided on the first temple 3, one end of the threaded rod 61 is mounted on the second temple 4, and the other end of the threaded rod 61 is slidably mounted in the movable groove 62, a T-shaped ring 65 is mounted on one side of the rotating knob 6, a T-shaped rotating groove 66 is provided on the first temple 3, and the T-shaped ring 65 is rotatably mounted in the T-shaped rotating groove 66. When using the glasses, the rotating knob 6 can be rotated according to one's own requirements, and the rotating knob 6 rotates to drive the threaded rod 61 to slide out or Slide into the movable groove 62 to adjust the distance between the first temple 3 and the second temple 4, that is, the length of the entire temple, so that it can be suitable for different wearers, which is convenient and fast and has high flexibility in use; two positioning blocks 63 are installed on the threaded rod 61, and two limiting grooves 64 are provided on the inner wall of the movable groove 62. The two positioning blocks 63 are respectively slidably installed in the two limiting grooves 64. The positioning blocks 63 and the limiting grooves 64 have a certain limiting effect on the threaded rod 61. When the rotating knob 6 is turned, the horizontal sliding of the threaded rod 61 can be limited to adjust the distance between the first temple 3 and the second temple 4.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
