DETAILED DESCRIPTION

[0022] The following is combined with Figure 1 —5 Provide further details on this application.

[0023] The embodiments of the present application disclose a pair of myopia prevention and control glasses.

[0024] like Figure 1 As shown, a pair of myopia prevention and control glasses includes two lower frames 1, an upper frame 10 is provided on the top of the two lower frames 1, support legs 11 are provided on the left and right sides of the two lower frames 1, lenses 12 are provided between the two lower frames 1 and the upper frame 10, and quick-disassembly assembly mechanisms 2 are provided on both sides of the two lower frames 1. The quick-disassembly assembly mechanism 2 includes a limiting component 20 and a plug-in component 21. The limiting component 20 includes a limiting block 206 for fixing the limit, and the plug-in component 21 includes a plug-in block 214 for plugging and fixing.

[0025] See also Figure 3 The limiting assembly 20 includes a fixed block 201 fixedly mounted on one end of the supporting leg 11, a plug-in cylinder 202 fixedly mounted on one side of the fixed block 201, a circular hole 203 is opened on the upper and lower sides of the plug-in cylinder 202, a sliding column 204 is slidably connected to the inside of the circular hole 203, a spring 205 is fixedly mounted on the inner top wall of the circular hole 203, the other end of the spring 205 is connected to the limiting block 206, and the limiting block 206 is fixedly mounted on one side of the sliding column 204. By manually holding the fixed block 201, The plug-in tube 202 is inserted into the outer side of the fixed column 212, and the limiting block 206 is squeezed by the plug-in block 214, so that the limiting block 206 moves to both sides, thereby compressing the sliding column 204 and separating the spring 1 205. When the plug-in block 214 is completely inserted into the interior of the plug-in tube 202, the spring 1 205 rebounds, thereby resetting the limiting block 206 and limiting the plug-in block 214, thereby achieving quick assembly and being used for disassembly and storage of glasses when not in use, thereby avoiding taking up a large space.

[0026] See also Figure 3The plug-in assembly 21 includes a mounting block 211 fixedly installed on both sides of the two lower frames 1, and a fixing column 212 is fixedly installed on one side of the mounting block 211. The plug-in block 214 is fixedly installed on one end of the fixing column 212. The outer wall of the fixing column 212 is slidably connected with a sliding block 213. The sliding block 213 contacts the plug-in block 214, and the plug-in block 214 is engaged with the limit block 206. When disassembling, the limit block 206 is driven to contact the sliding block 213 by pressing the fixed block 201 again. Because the sliding block 213 is conical, it will push the sliding block 213 and the plug-in block 214 to contact and close, thereby separating at the conical slope of the sliding block 213, realizing quick disassembly. When not in use outdoors, it can be disassembled and collected and put into a pocket, which effectively improves flexibility.

[0027] A clamping mechanism 3 is provided on the top of the two lower frames 1. The clamping mechanism 3 includes a clamping block 34 for blocking the clamping.

[0028] See also Figure 4 The clamping mechanism 3 includes two plugging slots 31 provided on the top of the two lower frames 1. The two plugging slots 31 are arranged opposite to each other. A sliding slot 32 is provided on one side of the plugging slot 31. A rectangular block 33 is slidably connected to the inside of the sliding slot 32. A pulling plate 36 is fixedly installed on one side of the rectangular block 33. A clamping block 34 is fixedly installed on the other end of the rectangular block 33. The clamping block 34 is located inside the plugging slot 31. By manually pulling the pulling plate 36, the rectangular block 33 slides inside the sliding slot 32, and the linked clamping block 34 compresses the spring 2 35, so that the clamping block 34 is separated from the clamping block 37, thereby realizing the separation of the upper frame 10 from the lower frame 1 for replacing the lens 12, avoiding pressing the lens 12 when taking down the lens 12, causing damage and wear of the lens 12, and effectively improving the convenience and protecting the safety of the lens 12.

[0029] See also Figure 4 A second spring 35 is fixedly installed on one side of the clamping block 34. The other end of the second spring 35 is connected to the inner side wall of the insertion slot 31. The second spring 35 is located above the rectangular block 33. The second spring 35 is installed to reset the clamping block 34 when the upper frame 10 is removed, so as to facilitate the next assembly.

[0030] See also Figure 4, two clamping blocks 37 are fixedly installed at the bottom of the upper frame 10, and the two clamping blocks 37 are symmetrically arranged. The two clamping blocks 37 are clamped with the clamping blocks 34. After the replacement is completed, the upper frame 10 and the lower frame 1 are manually held and closed and pressed to insert the clamping block 37 into the interior of the plug-in slot 31. During the insertion, the clamping block 37 will squeeze the clamping block 34, causing the clamping block 34 to move to one side, thereby compressing the second spring 35. When the clamping block 37 completely enters the interior of the plug-in slot 31, the second spring 35 presses the clamping block 34 to rebound, thereby causing the clamping block 34 to engage the clamping block 37;

[0031] See also Figure 2 One end of the support leg 11 is hinged to a hinge column 4, and the other side of the hinge column 4 is hinged to a rubber strip 5. A hinge column 2 6 is hinged between the two lower frames 1. The installed hinge column 4 is used to fold the support leg and the rubber strip 5, and the installed rubber strip 5 is used to prevent slipping.

[0032] The installed quick-disassembly assembly mechanism 2 is used to quickly disassemble the glasses and put them into a pocket when not in use, without taking up a large space for storage, and can be quickly assembled when in use without affecting use. The installed snap-on mechanism 3 is used to replace the lenses 12, avoiding manual pulling of the lenses 12 to separate the lenses 12 from the glasses frame, thereby achieving effective and quick replacement.

[0033] The implementation principle of the myopia prevention and control glasses of the embodiment of the present application is as follows: the quick disassembly assembly mechanism 2 is installed, which is used to quickly disassemble and put the glasses into a pocket when not in use, so as not to occupy a large space for storage, and to quickly assemble when in use without affecting use. The clamping mechanism 3 is installed to replace the lens 12, avoiding manual pulling of the lens 12 to separate the lens 12 from the glasses frame, thereby achieving effective and rapid replacement. By manually holding the fixing block 201, the plug-in tube 202 is inserted into the outer side of the fixing column 212, and the plug-in block 214 is inserted into the fixing column 212. The limit block 206 is squeezed to move the limit block 206 to both sides so that the sliding column 204 compresses the spring 1 205 and separates. When the plug-in block 214 completely enters the interior of the plug-in tube 202, the spring 1 205 rebounds, thereby resetting the limit block 206 and limiting the plug-in block 214, realizing rapid assembly and being used for disassembling and storing the glasses when not in use. When disassembling, the limit block 206 is driven to contact the sliding block 213 by pressing the fixed block 201 again. Since the sliding block 213 is tapered, it will push The sliding block 213 is in contact with the plug-in block 214, so that the sliding block 213 is separated at the conical slope, realizing quick disassembly. By manually pulling the pulling plate 36, the rectangular block 33 slides inside the sliding groove 32, and the linked clamping block 34 compresses the spring 2 35, so that the clamping block 34 is separated from the clamping block 37, realizing the separation of the upper frame 10 and the lower frame 1, which is used to replace the lens 12 and avoid pressing the lens 12 when taking off the lens 12, resulting in damage and wear of the lens 12. The spring 2 35 is installed to remove the upper frame 10. The card block 34 is reset to facilitate the next assembly. The upper frame 10 and the lower frame 1 are manually held and closed and pressed to insert the card block 37 into the interior of the insertion slot 31. During the insertion, the card block 37 will squeeze the card block 34, causing the card block 34 to move to one side, thereby compressing the spring 2 35. When the card block 37 completely enters the interior of the insertion slot 31, the pressure of the spring 2 35 causes the card block 34 to rebound, thereby causing the card block 34 to press against the card block 37. The hinge column 1 4 is installed to fold the support legs and the rubber strip 5, and the installed rubber strip 5 is used for anti-slip.

[0034] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
