[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] The utility model provides Figure 1-9The shown close-fitting glasses frame comprises a frame 12, two rotation limit assemblies and a temple extension assembly, a fixing rod 8 is provided on both side walls of the frame 12 near the two ends, and a connecting rod 17 is fixedly connected between the two fixing rods 8 on the same side, the two rotation limit assemblies comprise a mounting tube 7, a bearing 22 and a limit block 18, the bearings 22 are fixedly sleeved on the positions near the two ends of the connecting rod 17, and the two bearings 22 are respectively embedded in the top wall and the bottom wall of the mounting tube 7, an opening 3 is provided on the outer wall at an angle of 45 degrees on the side opposite to the frame 12, the limit block 18 is fixed on the outer wall near the middle position of the limit block 18, and a plurality of card grooves 25 are evenly spaced on the arc surface of the limit block 18 facing the opening 3, a limit cavity 20 is provided in the middle position of the bottom wall of the opening 3, and the middle position of the front and rear ends of the limit cavity 20 is provided. A limit opening 1 is provided, and a limit groove 21 matching the width of the limit opening 1 is provided in the middle of the top wall of the opening 3 near the inner wall of the mounting tube 7. The limit opening 1 on the inner wall of the mounting tube 7 is slidably connected to the limit groove 21 with the same matching limit plate 19. The bottom wall of the limit cavity 20 is provided with a second spring 23, and the other end of the second spring 23 is fixedly connected to a T-shaped slider 24 matching the limit cavity 20. The top wall of the T-shaped slider 24 is fixedly connected to one end of the bottom wall of the limit plate 19, and the connecting end of the T-shaped slider 24 passes through the limit opening 1 on the outer wall of the mounting tube 7 and extends to the outside of the mounting tube 7, and the connecting end of the T-shaped slider 24 is fixedly connected to the dial plate 2. The side wall of the mounting tube 7 perpendicular to the frame 12 is fixedly connected to the temple body 10, and the temple extension assembly is inserted into the temple body 10 from the other end of the temple body 10.

[0026] The user now pushes the dial plate 2 downward along the limit opening 1 outside the mounting tube 7, and the dial plate 2 drives the T-shaped slider 24 in the limit cavity 20 to move so that the limit plate 19 moves. The limit opening 1 inside the mounting tube 7 and the limit groove 21 limit the limit plate 19 to prevent it from deflecting. At this time, the second spring 23 is squeezed by the T-shaped slider 24 and contracts. When the limit plate 19 moves to the bottom of the card slot 25 of the limit block 18, the limit block 18 loses the limit of the limit plate 19. The user rotates the temple body 10 again. Since the fixing rod 8 fixes the connecting rod 17 and the bearing 22 on the connecting rod 17 acts, the temple body 10 is The rotation of the leg body 10 will drive the installation tube 7 to rotate, and the installation tube 7 will drive the limit plate 19 to rotate so that the limit plate 19 rotates to the bottom of different slots 25. The user rotates the leg body 10 to a suitable angle according to the contours of both sides of his face, and then releases the hand pressing the dial plate 2. At this time, the second spring 23 loses the limiting squeeze of the T-shaped slider 24 and rebounds. The second spring 23 drives the limit plate 19 to insert into the corresponding slot 25, limiting the installation tube 7 to prevent the installation tube 7 from rotating, completing the adjustment of the angle of the leg body 10, so that the leg body 10 is close to the contours of both sides of the user's face.

[0027] The temple extension assembly includes an auxiliary temple 6 and a block 4. A fixing hole 15 is provided at the middle position of the outer side wall of the auxiliary temple 6 near one end, and a first spring 16 is fixedly connected to the fixing hole 15. The other end of the first spring 16 is fixedly connected to the side wall of the block 4. A slot 14 is provided at the end of the temple body 10 away from the mounting tube 7. The auxiliary temple 6 is inserted into the temple body 10 from the socket of the slot 14. A slide groove 13 matching the block 4 is provided on the side wall of the slot 14, and a card hole 5 matching the block 4 is provided at equal intervals on the side wall of the slide groove 13. A protective cover 9 is provided at one end of the auxiliary temple 6.

[0028] When the user presses the card block 4, the card block 4 squeezes the first spring 16, pressing the card block 4 along the card hole 5 into the fixing hole 15 on the auxiliary temple 6, and at the same time pulls the auxiliary temple 6 to make the auxiliary temple 6 move in the slot 14 in the temple body 10, and the auxiliary temple 6 drives the card block 4 to move along the slide groove 13, and the slide groove 13 limits the card block 4 to prevent the first spring 16 from returning to the original position and rebounding. When the card block 4 moves to another card hole 5, the card block 4 loses the squeezing of the slide groove 13, and the rebound of the first spring 16 drives the card block 4 to fit into the card hole 5, limiting and fixing the auxiliary temple 6. The user can adjust the extended length of the auxiliary temple 6 according to his own situation, so that the auxiliary temple 6 is just placed on the ear. The protective cover 9 can increase the comfort of the user wearing glasses, and also prevent the auxiliary temple 6 from slipping off the ear.

[0029] A nose pad 11 is provided on the inner side of the connection in the middle of the frame 12 .

[0030] The nose pads 11 can distribute the weight of the glasses on the nose reasonably, so that the glasses can be placed on the nose more stably. On the other hand, the nose pads 11 can adjust the position of the glasses so that the glasses can be kept in a suitable position.

[0031] The top wall of the limiting groove 21 is at the same height as the top of the locking groove 25 , and the bottom wall of the arc-shaped locking groove 25 on one side wall of the limiting block 18 is located at half the height of the opening 3 .

[0032] When the limiting plate 19 is inserted into the slot 25, the limiting slot 21 limits the limiting plate 19 to prevent it from shaking. The bottom wall of the arc-shaped slot 25 of the limiting block 18 is located at half the height of the opening 3. The user can observe the position of the limiting plate 19 and the slot 25 from the opening 3, which is convenient for the user to insert the limiting plate 19 into different slots 25.

[0033] The slot 25 on one side of the arc surface of the limiting block 18 matches the curvature of the inner wall of the installation tube 7 .

[0034] The locking groove 25 of the arc surface of the limiting block 18 will not touch the inner wall of the installation tube 7 when the limiting block 18 rotates.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
