[0002] During the production and processing of artificial lenses, it is necessary to use a storage device to store the crystal blanks, and set a fan and other equipment in the storage device to ensure that the crystal blanks are in a dry state and improve the storage effect of the crystal blanks. However, in order to ensure that the fan can introduce air into the storage plate, most of the existing storage devices adopt an one-piece molding setting. The existing artificial lenses are of various types. In order to avoid mutual reactions between crystals, various crystals need to be stored independently. This obviously leads to the existing one-piece molding storage device being unable to store and dry artificial lenses. For this reason, we propose a crystal blank storage device for artificial lenses. Utility Model Content

[0026] Working principle: When in use, various artificial crystal blanks are stored in each storage plate 11 respectively, and then each storage plate 11 is installed on the front side of the upper end of the mounting seat 1 in sequence through the plug-in cooperation between the guide tube 14 and the through hole 10. During the movement of the storage plate 11, the contact effect between the positioning ring 15 and the positioning block 131 can push the positioning block 131 to expand outward, and at the same time, drive the rotating ring 13 to rotate. When the positioning ring 15 moves to the rear side of the rotating ring 13, the two are separated from each other. At this time, in the first spring Under the action of the spring 16, the rotating ring 13 can be driven to rotate, and through the sliding cooperation between the positioning block 131 and the annular positioning seat 12 and the rotating ring 13, each positioning block 131 is driven to shrink inward, so that the positioning block 131 is fitted with the outer periphery of the conduit 14, thereby achieving the effect of positioning the storage plate 11 at the front end of the mounting seat 1, and through the conduit 14, the storage plate 11 and the mounting seat 1 can be connected to each other, so that the fan 31 can introduce air into the storage plate 11, which is convenient for drying the crystal blank inside the storage plate 11.

[0027] Example 2

[0028] The positioning block 131 and the front and rear sides of the positioning ring 15 are arranged in an inclined manner to match each other.

[0029] The positioning block 131 and the front and rear sides of the positioning ring 15 are arranged to be matched with each other. When installing and removing the storage plate 11, the moving positioning ring 15 can drive the positioning block 131 to expand outward through the contact effect between it and the positioning block 131;

[0030] Through the sliding cooperation between the limiting slider 17 and the limiting groove 171, the movement direction of each positioning block 131 can be limited on the surface of the annular positioning seat 12, so that the rotating positioning ring 15 can drive each positioning block 131 to retract inward through the sliding cooperation between the inclined arc groove 181 and the cylindrical sliding shaft 18.

[0033] When the fan 31 is started and the outside air is introduced into the mounting base 1 through the fan 31, the flowing air pushes the sealing plate 22 to move, so that the sealing plate 22 and the sealing ring 21 are separated from each other, so that the air can circulate in the gap between the two, so that the air can be injected into the storage plate 11, and the air inside the storage plate 11 is discharged to the outside, so as to achieve the effect of drying the crystal blank inside the storage plate 11; when the fan 31 is turned off, the air inside the device stops flowing, and the sealing plate 22 loses the pushing effect of the air on it. At this time, under the action of the second spring 24, the sealing plate 22 can be driven to reset, so that the sealing plate 22 and the sealing ring 21 are re-fitted, so as to achieve the effect of sealing both sides of the storage plate 11.
