[0025] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.
[0026] Example 1
[0027] Reference Figure 1-4 , which is the first embodiment of the utility model, provides a lens placement rack for vacuum coating of optical lenses. The lens placement rack for vacuum coating of optical lenses includes a placement rack body 1. The number of placement rack bodies 1 is several. A supporting component 2 is provided inside the lower side of the placement rack body 1. A positioning component 3 is provided on the lower side of the placement rack body 1. A locking component 4 is provided on the upper side of the placement rack body 1.
[0028] The supporting component 2 includes two connecting plates 21 fixedly connected to both sides of the placing rack body 1, and the lower sides of the two connecting plates 21 are provided with storage grooves 22, and the two storage grooves 22 are hinged with support plates 23. A movable groove 24 is provided inside the placing rack body 1, and a pull rod 25 is slidably connected in the movable groove 24, and the pull rod 25 passes through the placing rack body 1. The outer wall of the pull rod 25 is fixedly connected to a limit plate 26, and the limit plate 26 is slidably connected in the movable groove 24. The top end of the limit plate 26 is fixedly connected to a pressure spring 27, and the top end of the pressure spring 27 overlaps the inner top end of the movable groove 24. A positioning hole 28 is provided inside the support plate 23, and the positioning hole 28 is communicated with the movable groove 24.
[0029] The support plate 23 is L-shaped, and the shape of the storage groove 22 matches the shape of the support plate 23 . A plurality of optical lenses are arranged inside the upper side of the placement frame body 1 , and a groove opened inside the placement frame body 1 passes through the placement frame body 1 .
[0030] During use, the two pull rods 25 are pulled upward so that the two pull rods 25 are disengaged from the positioning holes 28 inside the two connecting plates 21. At this time, the two support plates 23 hinged inside the two connecting plates 21 will rotate and be in a vertical state with the connecting plates 21. Then the two pull rods 25 are released. Because the limit plate 26 movable inside the movable groove 24 is fixed on the outside of the pull rod 25, after the pull rod 25 loses its restriction, the pressure spring 27 inside the movable groove 24 will push the limit plate 26 to reset the limit rod. At this time, the pull rod 25 will not enter the positioning hole 28, and will resist the side of the support plate 23 that contacts the inside of the storage groove 22, so that the support plate 23 is limited. At this time, the two support plates 23 under the two connecting plates 21 will support the placement rack body 1, which is convenient for supporting the placement rack body 1 and the optical lens inside it, so that the placement rack body 1 before and after coating does not need to be supported by other equipment, thereby reducing the space occupied by the vacuum coating working environment.
[0031] Example 2
[0032] Reference Figure 1-2 , which is the second embodiment of the utility model, and this embodiment is different from the first embodiment in that:
[0033] The positioning component 3 includes a positioning ring 31 which is sleeved on the outer side of the connecting plate 21 facing downward, and another connecting plate 21 is overlapped on the upper side of the fixed disk 32. The positioning ring 31 is fixedly connected to the fixed disk 32 through a plurality of connecting rods 34 in an annular array. A plurality of positioning grooves 33 are provided on the upper side of the positioning ring 31, and the plurality of positioning grooves 33 are arranged in an annular array. A plurality of card slots 35 are provided on the upper side of the fixed disk 32, and the plurality of card slots 35 are arranged in an annular array. The positioning grooves 33 are card-engaged with the connecting plate 21 located below, and another connecting plate 21 is overlapped inside the card slots 35. A rotating shaft 36 is fixedly connected to the top of the fixed disk 32, and a magnetic block 37 is fixedly connected to the inner bottom ends of the positioning grooves 33 and the card slots 35, and the magnetic block 37 is magnetically adsorbed to the support plate 23.
[0034] During use, the connecting plates 21 on both sides of the placement frame body 1 are inserted into the positioning groove 33 above the positioning ring 31, and the other connecting plate 21 will be placed in the card slot 35 above the fixed plate 32. The two connecting plates 21 are adsorbed by the card slot 35 and the magnetic block 37 inside the positioning groove 33. Because the fixed plate 32 is connected to the positioning ring 31 through the connecting rod 34, when the external driving device drives the rotating shaft 36 above the fixed plate 32 to rotate, the positioning ring 31 and the fixed plate 32 will cooperate to drive the placement frame body 1 and the optical lens inside it to rotate, which facilitates the positioning of both sides of the placement frame body 1, so that the placement frame body 1 can be quickly taken out from above the positioning ring 31 and the fixed plate 32, so as to improve the coating efficiency of the optical lens inside the placement frame body 1.
[0035] The remaining structures are the same as those of Example 1.

[0038] The locking component 4 includes an extrusion plate 41 overlapped on the top of the fixed plate 32, the extrusion plate 41 is overlapped on the upper side of several connecting plates 21 on the upper side, the extrusion plate 41 is sleeved on the outer surface of the rotating shaft 36, and a screw nut 42 is fixedly connected to the upper side of the extrusion plate 41. The outer surface of the rotating shaft 36 is provided with an external thread 43, and the screw nut 42 is threadedly connected to the outer surface of the rotating shaft 36 through the external thread 43.
[0039] During use, the screw nut 42 is turned so that the screw nut 42 starts to move along the thread direction of the outer screw on the outer side of the rotating shaft 36. When the screw nut 42 moves downward, the extrusion plate 41 fixed under the screw nut 42 will also move with it and be squeezed on top of several connecting plates 21 located above, which facilitates the locking of several connecting plates 21 located above, so as to facilitate the disassembly and positioning of the placement frame. At the same time, the stability of the placement frame body 1 and the optical lens inside it will also be guaranteed.
[0040] The remaining structure is the same as that of Example 2.
