[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0029] See also Figure 1-10 , the utility model provides a technical solution:
[0030] A vision detection device for physical examination comprises a detection mirror, which comprises a frame 1 and temples 2. A cover sheet 3 is slidably connected to the inner side of the frame 1, a slider 4 is fixedly connected to the inner side of the frame 1, a slideway 5 is provided on the outer side of the cover sheet 3, the slider 4 is located in the slideway 5 and the two slide together, a side support rod 6 and a positioning rod 7 are rotatably connected to the outer side of the frame 1, the ends of the side support rod 6 and the positioning rod 7 are rotatably connected, and a wiping strip 8 is rotatably connected between the side support rods 6, the side support rod 6 is a telescopic elastic rod, the end of the rotating shaft of the positioning rod 7 is fixedly connected to a limit plate 9, a protrusion 10 is fixedly connected to the inner side of the limit plate 9, a receiving cavity 11 is provided in the middle of the wiping strip 8, and a cotton strip 12 is provided at the end of the receiving cavity 11.
[0031] When in use, the wiping strip 8 is located at the front side of the mirror frame 1. Figure 3 In the position shown, the cover sheet 3 is fully pulled up, and there is no obstruction in the frame 1. Then the vision test can be carried out by wearing the detection glasses; when the side-view monocular vision is required, it is only necessary to push down the cover sheet 3 in front of the eye to cover the frame 1, so as to block the frame 1, and the corresponding monocular vision test can be carried out. The detection glasses are simple and convenient to wear, and the cover sheet 3 is pulled up and pushed down both conveniently and quickly, which can adapt to different testing needs, and no additional assistance is required, which is more labor-saving, and the glasses-like covering is more tight and reliable.
[0032] The wiping strip 8 is located on the front side of the frame 1 to avoid contact between the human face and the wiping strip 8. If contact occurs, it is the cover sheet 3 that contacts the human face. The accommodating cavity 11 is filled with alcohol or disinfectant. After use, the wiping strip 8 can be manually pulled back and flipped to the inside of the frame 1. By repeatedly pulling up the cover sheet 3, the inside of the cover sheet 3 can be wiped and cleaned by the cotton strip 12 on the inside of the wiping strip 8. The alcohol absorbed by the cotton strip 12 can be wiped and disinfected, thereby cleaning and disinfecting the inside of the cover sheet 3, which is convenient for the next person to use. Since the cover sheet 3 is closest to the human eyes, a comprehensive wiping and disinfection of the inside of the cover sheet 3 can greatly avoid some sources of infection and improve safety.
[0033] When the wiping strip 8 is pulled to move backward, the wiping strip 8 moves upward and then backward under the action of the positioning rod 7, and the arc-shaped trajectory passes over the top of the frame 1. At this time, the side support rod 6 is pulled to become longer and then restored, thereby adapting to the position of the wiping strip 8. Due to the action of the internal protrusion 10 of the limiting plate 9, the positioning rod 7 can only stay at the specified position on the front and rear sides of the frame 1, thereby limiting the staying position of the wiping strip 8, so that the cotton strip 12 can effectively contact the inner side of the covering sheet 3, thereby achieving cleaning and disinfection. After each person uses it, the next person can flip the wiping strip 8 for cleaning. The process is simple and convenient, and the cleaning parts are not easily lost.
[0034] Among them, a pull tab 13 is fixedly connected to the top of the covering sheet 3 to facilitate pulling up and pushing down the covering sheet 13. The covering sheet 3 is an opaque sheet, and the inner edge of the wiping strip 8 is larger than the outer edge of the frame 1. The wiping strip 8 can be flipped forward or backward with a minimum moving trajectory, making the entire device more compact and lightweight.
[0035] Among them, the side support rod 6 includes a bottom rod 61 and an upper rod 62. A guide groove 63 is opened on the inner side of the bottom rod 61. A guide bar 64 is fixedly connected to the bottom end of the upper rod 62. The guide bar 64 is located in the guide groove 63 and the two are slidably connected and a contraction spring 65 is fixedly connected between them.
[0036] When the side support rod 6 is stretched, the guide bar 64 moves upward along the guide groove 63 and pulls the contraction spring 65; the side support rod 6 can be lengthened and restored to the left and right of the contraction spring 65, which is more convenient.
[0037] Among them, a supplementary hole 19 is provided at the top of the accommodating chamber 11, and alcohol or the like can be supplemented into the accommodating chamber 11 through the supplementary hole 19. The width of the opening of the accommodating chamber 11 is smaller than the width of its inner cavity, so that the tampon 12 is more tightly connected and not easy to fall out.
[0038] Among them, it also includes a support frame 20, the support frame 20 includes a temple frame 21, a lens frame 22 and a nose wing frame 23, the nose wing frame 23 is fixedly connected to the temple frame 21 through a support bar 24, the temple frame 21, the lens frame 22 and the support bar 24 are each provided with a filling cavity 25, the temple frame 21, the lens frame 22 and the support bar 24 are each provided with a sinking frame 26 on the surface, the sinking frame 26 can be filled with cotton sheets, and a positioning column 27 is fixedly connected to the sinking frame 26 of the temple frame 21.
[0039] The nose wing frame 23 is an elliptical wrapping frame, a gasket 28 is arranged inside the nose wing frame 23 , micro holes 29 are opened on the surface of the nose wing frame 23 and the sinking frame 26 , and a filling hole 30 is arranged on the top of the filling cavity 25 of the temple frame 21 .
[0040] When the inspection mirror is not used for a long period of time, it can be placed on the support frame 20, so that the temple 2 is located at the temple frame 21, the cover sheet 3 is located at the lens frame 22, and the nose wing is located in the nose wing frame 23. Figure 7 As a result, when placing it, you only need to push it in directly. Under the limitation of the positioning column 27, the detection mirror will not fall off. During the placement process, the temple frame 21 wipes the inner side of the temple 2, and the nose wing frame 23 wipes the nose wing. After placement, the cover sheet 3 can be cleaned through the lens frame 22 by repeatedly pulling it up and down; thereby achieving a more thorough and comprehensive wiping and cleaning of the entire detection mirror, which is convenient for subsequent use and relatively clean and hygienic.
[0041] Similarly, alcohol or disinfectant is filled in the filling cavity 25, and the cotton piece is penetrated and soaked through the micropores on the surface of the sinking frame 26, so that it can be wiped and cleaned, and the gasket 28 cleans the nose wing; alcohol or disinfectant can be replenished through the filling hole 30, and it can be used repeatedly, which is more environmentally friendly and effective.
