Description

Technical Field

[0001] The utility model relates to the technical field of glasses, in particular to an earhook-free spectacle frame with a magnet and telescopic function. Background Art

[0002] Glasses are composed of lenses, lens frames and frames. The temple part of the frame is hung on the human ears. In order to ensure that the glasses will not fall off during exercise, glasses specially designed for wearing during exercise have emerged. A hanging loop that can be sleeved on the ear is added at the end of the temple to achieve the purpose of preventing falling. However, in the wearing of existing sports glasses, due to the different head sizes of different people, the same type of glasses cannot be suitable for many people to wear. It can only be adapted by replacing frames of different specifications, making the overall versatility of this type of sports glasses relatively low. For this reason, a public technology on the market proposes a pair of sports glasses, including: two frames for installing lenses, with nose pads arranged inside the frames; a bridge connecting and fixed between the two frames; two temples respectively rotatably connected to the outside of the two frames, and telescopic temples slidably installed on both temples. The telescopic temples are made of soft material, and a connecting piece is fixedly arranged at the end of the telescopic temple for movably connecting the ends of the two telescopic temples. The public technology claims that wearing the provided sports glasses has a convenient fixing method and can effectively prevent the glasses from slipping during exercise.

[0003] However, in the above structure, there is no positioning device between the temple and the telescopic temple. That is, during use, the telescopic temple and the temple are still in a sliding state. For users with a smaller head size, it cannot play a role in preventing falling, and the glasses will still fall off. Therefore, it is necessary to further improve its structure.

A step 702 is provided on one side of the hard rubber layer 7 facing the center line of the frame body 1 in the left-right direction. The snap-fit structure includes a docking groove 303, a snap-fastening inverted part 701, and a snap hole 304. The docking groove 303 is provided on the inner side wall of the hard rubber installation cavity 302 and is opposite to the step 702 on the hard rubber layer 7 in the left-right direction. The step 702 is snap-fitted to the inner side wall of the docking groove 303. The snap-fastening inverted part 701 is provided on the outer wall of the hard rubber layer 7 and behind the step 702. The snap hole 304 is provided on the inner side wall of the hard rubber installation cavity 302 and is opposite to the snap-fastening inverted part 701 in the left-right direction. One end of the snap-fastening inverted part 701 away from the hard rubber layer 7 is snap-fitted to the inner side wall of the snap hole 304. After the hard rubber layer 7 is inserted from the front end of the hard rubber installation cavity 302, the snap-fastening inverted part 701 is inserted into the snap hole 304 for snap-fitting, and then the step 702 is inserted into the docking groove 303 to improve the firmness of the snap-fitting, so that when the silica gel layer 3 is pulled to move along the outer wall of the TR layer 8 in the length direction, the hard rubber layer 7 and the silica gel layer 3 will not separate;

[0040] As Figure 1 , Figure 4 , Figure 5 and Figure 10 shown, a rectangular hole 703 that penetrates through the inside of the first sliding hole 706 is provided on the inner side wall of the step 702.

The positioning rod 705 is fixedly connected to the side of the spring tongue 704 facing the TR layer 8 and is located at one end away from the connection between the rectangular hole 703 and the spring tongue 704. The positioning rod 705 is used to cooperate with the positioning structure to control the position of the silica gel layer 3 on the outer wall of the TR layer 8;

[0041] As Figure 4 , Figure 5 , Figure 7 , Figure 9 and Figure 10As shown, in order to control the position of the silica gel layer 3 on the outer wall of the TR layer 8, a positioning structure for cooperating with the elastic positioning member to fix the position between the silica gel layer 3 and the TR layer 8 is provided on one side of the TR layer 8 facing the elastic positioning member. The positioning structure includes a terminal clamping position 801, three groups of positioning clamping points 802, and multiple groups of positioning holes 803. The multiple groups of positioning holes 803 are sequentially arranged in the front-back distribution on one side of the TR layer 8 facing the rectangular hole 703. The three groups of positioning clamping points 802 are sequentially arranged in the front-back distribution on one side of the TR layer 8 facing the rectangular hole 703 and are all located near one end of the TR layer 8 away from the spectacle frame body 1. The terminal clamping position 801 is arranged at the end of the TR layer 8 away from the spectacle frame body 1. When the silica gel layer 3 is pulled, the positioning rod 705 also moves accordingly. Each time the positioning rod 705 moves to correspond to a group of the multiple positioning holes 803, the positioning rod 705 can be inserted into the positioning hole 803 to maintain the current position of the silica gel layer 3 on the outer wall of the TR layer 8. The positioning holes 803 are mainly used to adjust the length of the temple during daily wearing. The usage method of the three groups of positioning clamping points 802 is the same as that of the positioning holes 803. However, the three groups of positioning clamping points 802 are all arranged at one end of the TR layer 8 away from the spectacle frame body 1, mainly to fix the position of the silica gel layer 3 when the silica gel layer 3 is pulled to a position close to the end during exercise. The three groups of positioning clamping points 802 combined with the terminal clamping position 801 can form three adjustment gears when cooperating with the positioning of the positioning rod 705, which can be suitable for different head shapes;

[0042] As Figure 2 , Figure 3 shown, in order to improve the anti-detachment effect during exercise, magnetic attraction structures are provided at the ends of both temples away from the spectacle frame body 1. The magnetic attraction structures include two groups of permanent magnets 5. Connecting heads 4 are provided at the ends of the silica gel layers 3 in both temples away from the spectacle frame body 1. Fixing holes are provided at the ends of the two connecting heads 4 away from the silica gel layers 3. The two groups of permanent magnets 5 are respectively fixedly connected to the inner side walls of the two fixing holes. Cover plates 6 are fixedly connected to the sides of the two groups of permanent magnets 5 away from the silica gel layers 3. The sides of the cover plates 6 away from the permanent magnets 5 are flush with the ends of the connecting heads 4 away from the silica gel layers 3. After the ends of the two temples are butted, they are fixed by the mutual attraction of the two groups of permanent magnets 5.

[0043] Working principle: The retractable ear hook-free eyeglass frame with magnets can be worn daily by holding the head with two sets of arc-shaped temples to play a fixing role and prevent loosening. The metal pin 9 made of stainless steel sheet has good elasticity. After being broken apart and worn, the metal pin 9 can form an environmental force through its own elasticity to prevent loosening during daily use. It is easier to set the positioning structure on the surface of the TR layer 8 than to process the positioning structure on the surface of the metal pin 9, which reduces the processing difficulty. After the hard rubber layer 7 is inserted from the front end of the hard rubber installation cavity 302, the snap-in fastener 701 is inserted into the inside of the snap-in hole 304 for snap-in, and then the step 702 is inserted into the docking groove 303 to improve the firmness of the snap-in, so that when the silicone layer 3 is pulled to move along the extension direction of the outer wall of the TR layer 8, the hard rubber layer 7 and the silicone layer 3 will not separate. The positioning rod 705 is used in conjunction with the positioning structure to control the silicone Layer 3 is located on the outer wall of TR layer 8. When the silicone layer 3 is pulled, the positioning rod 705 also moves with it. Each time the positioning rod 705 moves to correspond to one of the multiple positioning holes 803, the positioning rod 705 can be inserted into the positioning hole 803 to maintain the current position of the silicone layer 3 on the outer wall of TR layer 8. The positioning hole 803 is mainly used to adjust the length of the temple during daily wear, and the three groups of positioning points 802 are used in the same way as the positioning holes 803. However, the three groups of positioning points 802 are all set at the end of the TR layer 8 away from the frame body 1, mainly to fix the position of the silicone layer 3 when the silicone layer 3 is pulled to a position close to the end when exercise is required. The three groups of positioning points 802 are combined with the end position 801, which can form three adjustment gears when used to cooperate with the positioning of the positioning rod 705, which can be suitable for different head shapes. After the ends of the two groups of temples are docked, they are adsorbed and fixed to each other by two groups of permanent magnets 5.
