[0002] Film storage boxes play a crucial role in the inspection rooms of each workshop production line. It has the function of storing and placing glass, providing great convenience for the production inspection link, and is one of the indispensable auxiliary tools. However, in the actual use process of the existing film storage boxes, some obvious problems have emerged. It can only accommodate some glasses with smaller sizes. Once encountering glasses with larger sizes, either it cannot accommodate them, or the glasses will protrude more after barely accommodating them. This situation will bring many adverse consequences. On the one hand, the glasses protruding from the film storage box are easily damaged by external collisions, increasing the risk of glass damage; on the other hand, when copying and packing these glasses, since the glasses cannot be completely stored in the film storage box, more time and effort are required to adjust and fix them, greatly reducing the work efficiency. To sum up, the main disadvantage of the existing film storage boxes is that they are small in size and difficult to accommodate large-sized glasses. Summary of the Utility Model

Embodiment

[0026] Refer to the attached Figures 1 to 4 , a retractable film storage box, comprising a first film storage box body 1 and a second film storage box body 2. The first film storage box body 1 and the second film storage box body 2 are connected by a plurality of retractable devices 3. The retractable device 3 includes an inner rod 31 and an outer rod 32. The outer rod 32 is slidably sleeved outside the inner rod 31. A plurality of limiting holes 34 are equidistantly formed on the outer rod 32. A limiting head 33 is slidably arranged on the inner rod 31. One end of the limiting head 33 passes through a limiting hole 34, and the other end of the limiting head 33 is connected to a return spring 37. The return spring 37 is fixed on the inner rod 31.

[0027] One end of the inner rod 31 away from the outer rod 32 is fixedly provided with a first connection block 35, and one end of the outer rod 32 away from the inner rod 31 is fixedly provided with a second connection block 36. The second connection block 36 is fixedly connected to the first film storage box body 1, and the first connection block 35 is connected to the second film storage box body 2.

[0028] A first positioning plate 4 and a second positioning plate 5 are vertically arranged on the first film storage box body 1, and a third positioning plate 6 is vertically arranged on the second film storage box body 2. The first positioning plate 4 and the second positioning plate 5 are perpendicular to each other, and the inner surfaces of the second positioning plate 5 and the third positioning plate 6 are on the same plane.

[0029] Sponges are pasted on the first film storage box body 1 and the second film storage box body 2, and sponges are pasted on the inner walls of the third positioning plate 6, the first positioning plate 4, and the second positioning plate 5.

[0030] Working principle:

[0031] When it is necessary to adjust the length of the film storage box to adapt to glass of different sizes, the telescopic device 3 is operated. By pulling the outer rod 32 outwards, it slides along the inner rod 31. At this time, the limit head 33 is first pressed into the inner rod 31. As the outer rod 32 slides, when other limit holes 34 on the outer rod 32 move to the position of the limit head 33, the return spring 37 will pop the limit head 33 out and pass through the limit hole 34, so as to fix the adjusted length.

[0032] After the first film storage box body 1 and the second film storage box body 2 are connected by the telescopic device 3, the overall length of the film storage box can be flexibly adjusted according to the glass size. When the glass is placed, the first positioning plate 4, the second positioning plate 5 on the first film storage box body 1 and the third positioning plate 6 on the second film storage box body 2 jointly play a positioning role for the glass. Since the first positioning plate 4 and the second positioning plate 5 are perpendicular to each other, and the inner surfaces of the second positioning plate 5 and the third positioning plate 6 are on the same plane, the second positioning plate 5 and the third positioning plate 6 can position the long side of the glass, and the first positioning plate 4 can position the wide side of the glass, ensuring that the glass is placed more stably in the film storage box.

[0033] The sponge pasted on the inner walls of the first film storage box body 1, the second film storage box body 2, the third positioning plate 6, the first positioning plate 4 and the second positioning plate 5 can play a buffering and protecting role for the glass after the glass is placed in the film storage box, preventing the glass from being damaged during storage and handling.

[0034] The above-described embodiments only represent certain implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent of the present invention; it should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention; therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
