[0027] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0028] like Figures 1 to 5As shown, this utility model discloses a hinge adjustment structure for eyeglasses, which includes a frame 1 and a hinge 2 for connecting the temples 4; wherein, the frame 1 is provided with a mounting cavity 11 for cooperating with the hinge 2, and one end of the mounting cavity 11 forms a relief opening 111; a positioning member 3 is fixedly fitted in the mounting cavity 11, and the positioning member 3 is provided with at least two positioning parts 311; the hinge 2 has an adjustment part 21 and a connecting part 22, the adjustment part 21 of the hinge 2 is housed in the mounting cavity 11, the adjustment part 21 of the hinge 2 is slidably engaged with the positioning member 3 and the adjustment part 21 is selectively engaged with each positioning part 311 of the positioning member 3, and the connecting part 22 of the hinge 2 passes through the relief opening 111.

[0029] The working principle of this utility model is as follows: the user can move the hinge 2 as needed, so that the adjusting part 21 of the hinge 2 cooperates with different positioning parts 311 of the positioning member 3, thereby adjusting the relative position of the hinge 2 and the frame 1. In this way, the distance between the two temples of the glasses can be adjusted by adjusting the relative position of the hinge 2 and the frame 1 to suit different users.

[0030] In an embodiment of this utility model, each positioning part 311 of the positioning member 3 is recessed; and the adjusting part 21 of the hinge 2 is equipped with a movable spring pin 211, which is movably inserted into each positioning part 311 so that the adjusting part 21 selectively engages with each positioning part 311 of the positioning member 3. The two sides of the positioning part 311 form inclined guide surfaces 3111 to allow the spring pin 211 to enter and exit the positioning part 311.

[0031] In an embodiment of this utility model, the mounting cavity 11 of the frame 1 is provided with a mounting opening 112, which intersects with the clearance opening 111. The positioning member 3 is inserted into the mounting cavity 11 through the mounting opening 112. The positioning member 3 has two opposing positioning tracks 31. Each positioning track 31 of the positioning member 3 slides with the adjustment part 21 of the hinge 2. The positioning part 311 is provided on the inner side of at least one positioning track 31 of the positioning member 3. The adjustment part 21 of the hinge 2 may be provided with a sliding groove 212 that slides with the positioning track 31. At least one positioning track 31 of the positioning member 3 engages with the inner wall of the mounting cavity 11 to fix the positioning member 3 to the frame 1. The inner wall of the mounting cavity 11 may be provided with a locking post 113, and the positioning track 31 is provided with a locking groove 312 that engages with the locking post 113. The positioning component 3 and hinge 2 are installed into the mirror frame 1 in the following manner: first, the adjusting part 21 of hinge 2 is inserted into the mounting cavity 11 through the clearance opening 111, and then the positioning component 3 is inserted into the mounting cavity 11 through the mounting opening 112, so that the two positioning rails 31 of positioning component 3 slide into the sliding groove 212 of adjusting part 21, the slot 312 of positioning rail 31 of positioning component 3 engages with the locking post 113 on the inner wall of mounting cavity 11, and one positioning part 311 of positioning component 3 is inserted into the spring pin 211 of adjusting part 21.
