[0023] The following is an explanation and description of the technical solutions of the embodiments of the present invention in conjunction with the drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.
[0024] A contact lens placement rack according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings. Example
[0025] For easier understanding, see Figures 1 to 4 The present invention provides an embodiment of a contact lens placement rack, comprising a rack body 1, a plurality of storage slots 2 are provided inside the rack body 1, and a limited clamping mechanism is provided inside the rack body 1;
[0026] The limiting clamping mechanism includes a rotating plate 3, a pressing plate 4, a shaft body 6, a pull rope 8 and a pushing plate 13. An installation cavity 5 is opened on one side of the storage slot 2, and the shaft body 6 is fixedly installed inside the installation cavity 5. The rotating plate 3 is movably connected to the side wall of the shaft body 6 through a torsion spring 7. The pressing plate 4 is fixedly installed at one end of the rotating plate 3. A movable plate 10 is installed inside the frame body 1, and the pushing plate 13 is installed at one end of the movable plate 10. One end of the rotating plate 3 is connected to the bottom of the pushing plate 13 through a pull rope 8. A movable cavity 11 is opened at the bottom of the storage slot 2, and the movable plate 10 is slidably connected to the inside of the movable cavity 11. A limiting plate 12 is fixedly installed on the side wall of the movable plate 10, and a spring is fixedly installed between one end of the limiting plate 12 and the inner wall of the movable cavity 11.
[0027] When the push plate 13 moves upward, the rotating plate 3 can drive the holding plate 4 to rise. When the contact lens needs to be placed in the storage slot 2, the movable plate 10 is pushed upward to raise the pushing plate 13, and then the contact lens is placed on the pushing plate 13. When a semi-hard or soft contact lens is placed, the movable plate 10 is pulled downward after waiting for the contact lens to return to its original shape to lower the pushing plate 13. At this time, the rotating plate 3 is rotated to one side under the action of the torsion spring 7, so that the holding plate 4 moves to the inside of the storage slot 2, and the contact lens is clamped and fixed in the storage slot 2 by the holding plate 4. The contact area with the contact lens is reduced during fixation to avoid damage to the contact lens.
[0028] In some embodiments, as Figure 2As shown, a plurality of guide wheels 9 are rotatably connected inside the frame body 1 , and the pull rope 8 is movably connected inside the frame body 1 through the guide wheels 9 .
[0029] It should be noted that the provision of the guide wheel 9 can reduce the wear of the pull rope 8 when it slides inside the frame body 1 .
[0030] In some embodiments, as Figure 4 As shown, the holding plate 4 is an arc-shaped plate, and the holding plate 4 matches the storage slot 2.
[0031] It should be noted that, by configuring the holding plate 4 to be arc-shaped, the holding plate 4 can be matched with the storage tank 2 to clamp the contact lenses in the storage tank 2 . Example
[0032] In some embodiments, as Figure 3 As shown, a card slot 14 is provided inside the storage tank 2 , a pushing plate 13 is located inside the card slot 14 , and a protective pad 15 is fixedly installed on the top of the pushing plate 13 .
[0033] It should be noted that, by providing the card slot 14 , the convex point at the center of the contact lens can be located inside the card slot 14 , thereby preventing the convex point at the center of the contact lens from being deformed, and by providing the protective pad 15 , scratches on the contact lens can be avoided.
[0034] The pull rope 8 and the guide wheel 9 in the present invention are well-known components and will not be described in detail here.
[0035] Working principle: When it is necessary to place the contact lens in the storage slot 2, the movable plate 10 is pushed upward to raise the pushing plate 13. At this time, the rotating plate 3 drives the holding plate 4 to rise, and then the contact lens is placed on the pushing plate 13. When placing semi-hard or soft contact lenses, wait for the contact lenses to return to their original shape and then pull the movable plate 10 downward to lower the pushing plate 13. At this time, the rotating plate 3 rotates to one side under the action of the torsion spring 7, so that the holding plate 4 moves to the inside of the storage slot 2, and the contact lens is clamped and fixed in the storage slot 2 by the holding plate 4. When fixing, the contact area with the contact lens is reduced to avoid damage to the contact lens.
