[0002] Traditional plastic eyeglass frames are usually made of acetate polymers. Since the thickness of the eyeglass frames themselves is usually more than 3mm, the connection between the eyeglass frames and the ear hooks is very complex.

[0003] For example, an ultra-thin plastic eyeglass frame with the authorization announcement number "CN201607580U" solves the problem of existing ultra-thin plastic eyeglass frames being hinged into an integral structure. This connection method is relatively complex to process. The above-mentioned L-shaped connector is connected between the frame body and the ear hook. No metal connector needs to be embedded during plastic molding. Only the installation position needs to be reserved. The structure is simple, the assembly installation is more convenient, and it is more suitable as a connection structure for ultra-thin plastic frames. Considering the existing ultra-thin plastic eyeglass frames, the frames are basically decorated with lenses in a clamping manner. When the frame is dropped from a height, it is easy to detach, resulting in wear of the lenses and economic losses. Utility Model Content

[0019] The present invention will be further described below with reference to the accompanying drawings: Example 1

[0020] See also Figure 1-6: In this embodiment, a pair of shatter-resistant plastic glasses that are easy to replace lenses include an eye leg 1 and a temple cover 2. The inner wall of the eye leg 1 is fixedly connected to the temple cover 2, the eye leg 1 is fixedly connected to the hinge 3 by a bolt, the hinge 3 is fixedly connected to the eyeglass frame 4 by a bolt, the inner wall of the eyeglass frame 4 is movably connected to the lens 5, and the outer wall of the eyeglass frame 4 is connected to a splicing mechanism 6.

[0021] The splicing mechanism 6 includes a connecting tube 601, which is deformed by the spring sheet 603 due to the external force, so that the position of the block 602 on the spring sheet 603 changes, which can control the clamping and splicing of the block 602 and the fixed tube 801. The end of the connecting tube 601 is fixedly connected to the eyeglass frame 4, the inner wall of the connecting tube 601 is movably connected to the block 602, the lower end of the block 602 is fixedly connected to the spring sheet 603, and the end of the spring sheet 603 is fixedly connected to the connecting tube 601.

[0022] The outer wall of the eyeglass frame 4 is fixedly connected to the silicone sleeve 7, and the outer wall of the hinge 3 is sleeved through the silicone sleeve 7 to prevent the hinge 3 from bending and clamping the hair. The inner wall of the silicone sleeve 7 is movably connected to the hinge 3. The outer wall of the clamping block 602 is connected to the fixing mechanism 8, which enters the fixing tube 801 through the clamping block 602, so that the fixing tube 801 and the connecting tube 601 are fixed. The fixing mechanism 8 includes a fixing tube 801, the inner wall of the fixing tube 801 is clamped with the clamping block 602, the end of the fixing tube 801 is fixedly connected to the limiting ring 802, and the outer wall of the limiting ring 802 is fixedly connected to the outer frame 803;

[0023] Pushing the outer frame 803 will drive the fixing tube 801 to enter the connecting tube 601. The fixing tube 801 squeezes the block 602 to deform the spring sheet 603 until the block 602 enters the fixing tube 801, thereby fixing the fixing tube 801 and the connecting tube 601, and achieving splicing between the outer frame 803 and the glasses frame 4. The outer frame 803 and the glasses frame 4 clamp and fix the lens 5, and will not fall off due to external force, so it can play a role in resisting falling.

[0024] The outer wall of the outer frame 803 is threadedly connected to the decorative cap 9 , the outer wall of the decorative cap 9 is tightly pressed against the limiting ring 802 , the inner wall of the outer frame 803 is tightly pressed against the lens 5 , and the inner side of the glasses frame 4 is fixedly connected to the nose bridge 10 .

[0025] Working principle:

[0026] By inserting the fixing tube 801 into the outer frame 803, the limiting ring 802 on the fixing tube 801 will limit the detachment from the outer frame 803, pushing the outer frame 803 will drive the fixing tube 801 to enter the connecting tube 601, and the fixing tube 801 squeezes the block 602 to deform the spring piece 603 until the block 602 enters the fixing tube 801, so that the fixing tube 801 and the connecting tube 601 are fixed, and the outer frame 803 and the glasses frame 4 are spliced. The outer frame 803 will also produce an effect of squeezing and fixing the lens 5, and at the same time, the decorative cap 9 is screwed into the outer frame. 803, the decorative cap 9 plays a decorative role in covering the limit ring 802. When unscrewing the decorative cap 9, use a tool to move the spring piece 603 in the opposite direction. The spring piece 603 drives the block 602 to separate from the fixed tube 801, and the fixed tube 801 and the connecting tube 601 are also separated. The lens 5 can be taken out from between the outer frame 803 and the glasses frame 4, and the effect of installing and replacing the lens 5 can be achieved. The outer frame 803 and the glasses frame 4 clamp the lens 5 and will not fall off due to external force. The overall material is also made of plastic, which can play a role in resistance to falling.
