Detailed implementation manner

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1 - 5 , an embodiment provided by the present invention: An adjustable fresh-keeping film box includes a placement box 2 for placing and storing the main body 12 of the fresh-keeping film. It is connected with a mounting plate 1 through a mounting mechanism, which is convenient for splicing and disassembly operations, does not affect normal placement and use, and is also convenient for disassembly and replacement operations after use. In order to facilitate the placement and positioning of the main body 12 of the fresh-keeping film, without affecting the subsequent pulling-out operation, and at the same time adapting to the assembly of the main body 12 of the fresh-keeping film with different length specifications, connecting components are symmetrically arranged on the inner wall of the placement box 2. One group of connecting components is connected with the inner wall of the placement box 2 through an adjusting component, which can conveniently adjust its position inside the placement box 2, thereby facilitating the installation and disassembly operations, and can also be adapted to the use of the main body 12 of the fresh-keeping film with different lengths. In order to conveniently pull out and use the main body 12 of the fresh-keeping film, an empty slot 3 is opened in the middle of the top end of the placement box 2, and a vertical plate 4 of the cutting component is also welded on the top end. A cutter 6 is installed on the side wall of the vertical plate 4 (on the side close to the empty slot 3), which can conveniently cut the main body 12 of the fresh-keeping film. In order to ensure safety, a protective sleeve 5 is sleeved outside the cutter 6, which can protect the cutter 6 when not in use and ensure safety.

[0023] Please refer to Figures 1 - 5 , in order to conveniently connect and assemble the whole, facilitate use, and also facilitate the disassembly of the placement box 2, and facilitate the replacement operation of the main body 12 of the fresh-keeping film after use, insertion posts 7 of the mounting mechanism are symmetrically welded on the side wall of the placement box 2, and corresponding insertion holes 8 for the insertion posts 7 to be inserted are opened on the mounting plate 1. An anti-slip sleeve 9 is bonded to the inner wall of the insertion hole 8 to ensure the insertion effect. For the convenience of installation operation, two groups of guide plates 11 are symmetrically welded at the bottom end of the placement box 2, and corresponding guide grooves 10 for the guide plates 11 to slide reciprocally are opened on the mounting plate 1, which is convenient for installation operation.

[0024] Please refer to Figures 1 - 5, in order to facilitate the installation of the fresh-keeping film main body 12, facilitate the subsequent pulling out and use, facilitate the replacement after use, facilitate the adjustment of the distance between the two connecting components, and facilitate the adaptation to the fresh-keeping film main body 12 of different lengths, circular plates 14 of the connecting components are symmetrically arranged inside the placing box 2. Connecting columns 15 are rotatably arranged on the side walls of the two circular plates 14 close to each other (which can be rotatably connected through bearings, a relatively mature technology, not elaborated here). A connecting rotating cylinder 13 is inserted between the two connecting columns 15. The fresh-keeping film main body 12 is wound around the connecting rotating cylinder 13. One of the circular plates 14 is connected to the placing box 2 through an adjusting component, and the other circular plate 14 is fixedly welded to the inner wall of the placing box 2. Or both circular plates 14 can be connected to the inner wall of the placing box 2 through the adjusting component. The adjusting component includes symmetrically arranged guiding telescopic rods 16 arranged between the inner wall of the placing box 2 and one of the circular plates 14. A spring 17 is sleeved outside the guiding telescopic rod 16, which can facilitate the reciprocating movement of the circular plate 14, and thus facilitate the installation and disassembly operations of the fresh-keeping film main body 12.

[0025] Working principle: When the present utility model is in use, by pressing the circular plate 14 connected to the guiding telescopic rod 16, the guiding telescopic rod 16 and the spring 17 are stressed and contracted to store potential energy, moving away from the other circular plate 14. Thus, it is convenient to place the connecting rotating cylinder 13 between the two connecting columns 15, first insert it into the connecting column 15 of the circular plate 14 on the inner wall of the placing box 2, and then reset under the action of the potential energy of the spring 17, driving the circular plate 14 to move and reset. Then its connecting column 15 is inserted into the other end of the connecting rotating cylinder 13 to complete the assembly. The connecting rotating cylinder 13 and the connecting column 15 rotate on the circular plate 14, facilitating the subsequent pulling out and use of the fresh-keeping film main body 12. At this time, the placing box 2 and the mounting plate 1 can be spliced through the guide plate 11 cooperating with the guide groove 10, and then the inserting column 7 is inserted into the inserting hole 8, and the assembly can be completed in cooperation with the anti-slip sleeve 9. When in use, the fresh-keeping film main body 12 can be pulled out from the empty groove 3. When it needs to be cut off, the protective sleeve 5 can be removed from the cutter 6, and the fresh-keeping film main body 12 can be cut off through the cutter 6. After use, the protective sleeve 5 can provide protection for the cutter 6 to ensure safety. After the fresh-keeping film main body 12 is used up, by pulling the placing box 2, the inserting column 7 leaves the inserting hole 8, and the guide plate 11 slides in the guide groove 10 to complete the disassembly. Then, by pushing the circular plate 14, the guiding telescopic rod 16 and the spring 17 are contracted, and the two connecting columns 15 move away, facilitating the removal and replacement of the fresh-keeping film main body 12.
