[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4 The eye protection device of the present invention comprises a frame 1, the front end of the frame 1 is covered with a lens 2, and the top end of the lens 2 is connected to a connecting block 3, and the side wall of the frame 1 is provided with a headband, so that the frame 1 can be easily worn on the head. The specific wearing principle is the prior art, which will not be described in detail here. A connecting plate 4 is distributed on the side of the connecting block 3, and a fixing bar 5 is connected to the top end of the frame 1, and a receiving groove 6 is opened inside the fixing bar 5, and a threaded rod 7 is connected to the inner wall of the receiving groove 6 through a bearing, and two groups of threaded sleeves 9 are sleeved on the outer side of the threaded rod 7, and the sides of the threaded sleeve 9 are connected to the clamping plate 10 through a connecting rod, and the outer surface of the threaded rod 7 is provided with two groups of external threads with opposite rotation directions, so that when the threaded rod 7 rotates, the two groups of threaded sleeves 9 can be driven to move in opposite directions inside the receiving groove 6, and a slideway compatible with the connecting rod is opened inside the fixing bar 5, and the movement requirement of the threaded sleeve 9 can be effectively met by opening the slideway.

[0023] Further, see Figure 3 and Figure 4 It can be known that the sides of the clamping plates 10 that are close to each other are respectively connected with embedded blocks 11, and the side walls of the connecting plate 4 are provided with limiting grooves that are compatible with the embedded blocks 11. When in use, the clamping effect of the connecting plate 4 can be effectively improved through the mutual cooperation of the embedded blocks 11 and the limiting grooves.

[0024] Further, see Figure 2 and Figure 3 It can be known that a spring 13 is connected to the side of the connecting block 3, a groove is opened inside the connecting plate 4, and the inner wall of the groove is connected to the other end of the spring 13. The spring 13 connected to the side wall of the connecting block 3 can facilitate the staff to pull the lens 2 and leave a certain gap between it and the frame 1 to facilitate the staff to clean the lens 2.

[0025] Further, see Figure 2 and Figure 3 It can be known that a guide rod 12 is connected to the side of the connecting block 3, and a guide groove adapted to the guide rod 12 is opened inside the connecting plate 4. Through the mutual cooperation of the guide rod 12 and the guide groove, the connecting block 3 can be guided, thereby effectively improving the stability of the connecting block 3 during movement.

[0026] Further, see Figure 4 It can be seen that a sealing strip 14 is glued to the edge of the lens 2, and a sealing groove compatible with the sealing strip 14 is opened on the inner wall of the frame 1. Through the mutual cooperation of the sealing strip 14 and the sealing groove, the sealing of the lens 2 covering the front end of the frame 1 can be effectively guaranteed, and the protective effect of the device can be effectively guaranteed.

[0027] Further, see Figure 2It can be known that the side of the lens 2 is connected with a paddle 15, and the paddles 15 are symmetrically distributed at the left and right ends of the lens 2. When in use, the two groups of paddles 15 can facilitate the staff to pull the lens 2 to move.

[0028] Further, see Figure 2 and Figure 3 It can be seen that the end of the threaded rod 7 extends to the outside of the fixed bar 5 and is connected to a rotating piece 8, and the rotating pieces 8 are distributed on the outer surface of the threaded rod 7 in a circular array structure. By connecting multiple groups of rotating pieces 8, it is convenient for the staff to rotate the threaded rod 7, thereby effectively improving the convenience of the device during use.

[0029] Working principle: When the utility model is used, the staff can first wear the frame 1 on the face, so that the eye protection can be achieved during the cleaning process. When a lot of water mist appears inside the lens 2, the staff can manually pull the paddle 15, so that the spring 13 connected to the top of the lens 2 is stressed at the same time, so as to drive the spring 13 connected to the inner side thereof to be stretched. Through the deformation of the spring 13, the lens 2 and the frame 1 can be separated. At this time, there will be a certain gap between the lens 2 and the frame 1. Then the staff can extend a wiping tool such as a paper towel or a glasses cloth into the gap to clean the water mist on the inner wall of the lens 2. After the cleaning is completed, the lens 2 can be reset by the elastic force of the spring 13, so that the lens 2 is in contact with the frame 1 again.

[0030] When the lens 2 that has been used for a period of time becomes scratched, the staff can manually rotate the rotating piece 8, thereby driving the rotation of the threaded rod 7. While the threaded rod 7 is rotating, the two sets of threaded sleeves 9 can rotate in opposite directions inside the fixing bar 5, so that the two sets of clamps 10 are forced to move away from each other, so that the embedded block 11 connected to the inner side of the clamp 10 is pulled out from the inside of the connecting plate 4. Then the staff can remove the connecting plate 4 together with the scratched lens 2, and install a new set of lenses 2 at the front end of the frame 1. The above is the entire working principle of the utility model.

[0031] In the present invention, the installation method, connection method or setting method of all the components mentioned above are common mechanical methods, and the specific structures, models and coefficient indicators of all its components are its own technology. As long as it can achieve its beneficial effects, it can be implemented, so it will not be elaborated.

[0032] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited by the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
