Description

Technical Field

[0001] This utility model relates to the field of anti-fog film packaging technology, and more specifically, to an anti-fog film roll packaging clamp. Background Technology

[0002] Anti-fog goggles are specially designed goggles that work by preventing water vapor from condensing on the lens surface to form fog, thus maintaining a clear view and providing good visibility. The surface of the anti-fog goggles is covered with an anti-fog film containing super-hydrophilic nanomaterials. This causes water adsorbed on the lens to dissociate into tiny water droplets. Due to the film's excellent hydrophilicity, water completely wets and spreads upon contact with the film surface. When the water absorption limit is reached, a thin, transparent water film layer is formed, reducing the angle of contact between the film and water. This makes the surface tension of the film and the surface tension of the water very close, preventing water from adhering to the film surface and achieving the anti-fog purpose.

[0003] A search revealed, for example, a Chinese patent application with publication number CN221478083U discloses an anti-fog film roll packaging clamp. This clamp features a design with support columns at both ends, one end of which has a telescopic support column that can be adjusted for longer anti-fog film rolls, ensuring support for the middle section and preventing collapse during long-term storage or bumpy transportation. Installation is also simple and quick; simply place the support columns into the roll. Dustproof film assembly and clamping modules are designed on both sides of the fixing modules at both ends. The right-side fixing module has a film outlet inside its middle section, while the other-side fixing module has a clamping ring on its middle section to press the dustproof film. A user-friendly handle is also provided on its surface, and an engagement port is designed at the bottom to prevent easy repositioning.

[0004] However, when using the above solution, the telescopic column is inserted into the anti-fog film roll. When the anti-fog film roll is being moved, it is difficult to fix the anti-fog film roll in place, causing it to rotate and resulting in the anti-fog film roll becoming loose and damaged. In addition, the telescopic column of the above solution is of a single size, which is not suitable for anti-fog film rolls of different sizes. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an anti-fog film roll packaging clamp. The technical problem to be solved is that the telescopic column is difficult to fix the anti-fog film roll and it is easy to rotate. The telescopic column has a single size and is not suitable for anti-fog film rolls of different sizes.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an anti-fog film roll packaging clamp, comprising a packaging box:

[0007] A first rubber plate and a post are fixedly provided on one side of the inner wall of the packaging box. The first rubber plate is located on the outer surface of the post. A second rubber plate is movably provided on the inner side of the packaging box. A closing plate is movably provided on one side of the packaging box.

[0008] The inner side of the insert post is provided with two expansion support devices that can expand and press against the inner wall of the anti-fog film roll, which are used to fix the anti-fog film roll from the inner wall of the anti-fog film roll according to the size of the anti-fog film roll.

[0009] The expansion support device includes a rotating rod, which is movably disposed inside the insert post. One end of the rotating rod passes through one side of the packaging box, and a rotating disk is fixedly provided at one end of the rotating rod. The other end of the rotating rod passes through one end of the insert post.

[0010] One side of the closed plate is provided with a compression fixing device that can press and fix the anti-fog film roll, which is used to fix the anti-fog film roll.

[0011] In a preferred embodiment, four recycling slots are provided on the outer surface of the insertion post, and an anti-slip plate is movably provided inside the recycling slots. Two fixing frames are fixed inside the insertion post, and a transmission rod is hinged to the inside of the groove on the outer surface of the fixing frame through a hinge rod. One end of the transmission rod is connected to one side of the anti-slip plate through a hinge seat.

[0012] In a preferred embodiment, the outer surface of the rotating rod is provided with two threaded grooves, and a threaded sleeve is threadedly connected to the threaded grooves on the outer surface of the rotating rod. Four pull rods are hinged to the outer surface of the threaded sleeve through a hinge rod, and one end of the pull rod is hinged to one end of the anti-slip plate through the hinge rod.

[0013] In a preferred embodiment, the compression fixing device includes four telescopic rods, which are respectively fixedly disposed on one side of the closing plate, and the movable ends of the four telescopic rods are fixedly connected to one side of the second rubber plate.

[0014] In a preferred embodiment, a spring is movably disposed between the closing plate and the second rubber plate, the spring being located on the outer surface of the telescopic rod.

[0015] In a preferred embodiment, hinges are fixedly provided at the upper and lower ends of the closing plate, and a rotating plate is fixedly provided at the movable end of the hinge.

[0016] In a preferred embodiment, the packaging box is hinged to limit plates on both sides by hinge rods, and the inner groove of the rotating plate is adapted to the limit plates.

[0017] The technical effects and advantages of this utility model are as follows:

[0018] 1. This utility model involves inserting a post into the inside of an anti-fog film roll. When the anti-fog film roll is located on one side of the first rubber plate, rotating the rotating disk causes the rotating rod to rotate. Because the outer surface of the rotating rod has two threaded grooves, it drives two threaded sleeves to move. The anti-fog plate is pulled by a pull rod. The anti-fog plate is hinged through two transmission rods, and the transmission rods are hinged through a fixing frame. Therefore, when the anti-fog plate is pulled to one side, it will protrude from the recycling groove and extend into the inner wall of the anti-fog film roll. The anti-slip effect of the anti-fog plate is used to fix the anti-fog film roll. According to the outward expansion of the anti-fog plate, it can be used for anti-fog film rolls of different sizes, thus improving the applicability of this utility model.

[0019] 2. This utility model uses a closing plate placed on one side of the packaging box. One end of the insert post is inserted into the slot. With the cooperation of a spring and a telescopic rod, the second rubber plate can be moved to squeeze the anti-fog film roll inside the packaging box, preventing the anti-fog film roll from loosening and being damaged during transportation. When the closing plate is placed on one side of the packaging box, by rotating the two rotating plates, the limiting plate passes through the through groove of the rotating plate and rotates the limiting plate, thereby limiting the rotating plate. Overall, it improves the convenience of packaging the anti-fog film roll, reduces the use of unnecessary tools, and can prevent the anti-fog film roll from loosening. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art of anti-fog film roll packaging without creative effort are within the scope of protection of the present utility model.

[0027] like Figure 1 and 2 As shown, this utility model provides an anti-fog film roll packaging clamp, including a packaging box 1:

[0028] A first rubber plate 6 and a post 8 are fixedly provided on one side of the inner wall of the packaging box 1. The first rubber plate 6 is located on the outer surface of the post 8. A second rubber plate 7 is movably provided on the inner side of the packaging box 1. A closing plate 4 is movably provided on one side of the packaging box 1.

[0029] After packaging, anti-fog film is usually stored in rolls. In order to be able to use anti-fog film rolls of different sizes and improve the applicability of this utility model, the inner side of the insert post 8 is provided with two expansion support devices 2 that can expand and press against the inner wall of the anti-fog film roll, which are used to fix the anti-fog film roll from the inner wall according to the size of the anti-fog film roll.

[0030] like Figure 3 and 4As shown, the expansion support device 2 includes a rotating rod 22, which is movably disposed inside the insert post 8. One end of the rotating rod 22 passes through one side of the packaging box 1, and a rotating disk 5 is fixedly mounted on one end of the rotating rod 22. The other end of the rotating rod 22 passes through one end of the insert post 8. Four recycling slots 21 are formed on the outer surface of the insert post 8. Anti-slip plates 25 are movably mounted inside the recycling slots 21. Two fixing brackets 26 are fixed inside the insert post 8. A transmission rod 27 is hinged to the inside of the groove on the outer surface of the fixing bracket 26 via a hinge rod. One end of the transmission rod 27 is connected to one side of the anti-slip plate 25 via a hinge seat. Two threaded grooves are formed on the outer surface of the rotating rod 22. A threaded sleeve 23 is threadedly connected to the threaded grooves on the outer surface of the rotating rod 22. A threaded sleeve 23 is hinged to the outer surface of the threaded sleeve 23 via a hinge rod. Four pull rods 24 are provided, one end of which is hinged to one end of the anti-fog film roll 25 via a hinge rod. By inserting the insert post 8 into the anti-fog film roll, when the anti-fog film roll is located on one side of the first rubber plate 6, the rotating disk 5 is rotated, causing the rotating rod 22 to rotate. Since the outer surface of the rotating rod 22 has two threaded grooves, it drives the two threaded sleeves 23 to move. The pull rods 24 are used to pull the anti-fog film roll 25. The anti-fog film roll 25 is hinged through two transmission rods 27, and the transmission rods 27 are hinged through the fixing frame 26. Therefore, when the anti-fog film roll 25 is pulled to one side, it will protrude from the recycling groove 21, thereby extending into the inner wall of the anti-fog film roll. The anti-slip effect of the anti-fog film roll 25 is used to fix the anti-fog film roll. According to the outward expansion of the anti-fog film roll 25, it can be used for anti-fog film rolls of different sizes, thus improving the applicability of this utility model.

[0031] Furthermore, in order to improve the convenience of packaging anti-fog film rolls, reduce the use of unnecessary tools, and prevent the anti-fog film rolls from loosening, a squeezing and fixing device 3 is provided on one side of the closing plate 4 to support the anti-fog film rolls and fix them in place.

[0032] like Figure 5As shown, the compression fixing device 3 includes four telescopic rods 32, which are respectively fixedly installed on one side of the closing plate 4. The movable ends of the four telescopic rods 32 are fixedly connected to one side of the second rubber plate 7. A spring 33 is movably installed between the closing plate 4 and the second rubber plate 7. The spring 33 is located on the outer surface of the telescopic rods 32. Hinges 34 are fixedly installed at the upper and lower ends of the closing plate 4, and a rotating plate 35 is fixedly installed at the movable end of the hinge 34. Limiting plates 36 are hinged to both sides of the packaging box 1 through hinge rods. The inner groove of the rotating plate 35 is adapted to the limiting plate 36. The closing plate 4 is placed on one side of the packaging box 1. One end of the insert post 8 is inserted into the slot 31. With the cooperation of the spring 33 and the telescopic rod 32, the second rubber plate 7 can be actuated to squeeze the anti-fog film roll inside the packaging box 1, which prevents the anti-fog film roll from coming loose during transportation and causing damage to the anti-fog film. When the closing plate 4 is placed on one side of the packaging box 1, by rotating the two rotating plates 35, the limiting plate 36 passes through the through groove of the rotating plate 35, and the limiting plate 36 is rotated to limit the rotating plate 35. This improves the convenience of packaging the anti-fog film roll, reduces the use of unnecessary tools, and prevents the anti-fog film roll from coming loose.

[0033] The working principle is as follows: When using this utility model, the insert 8 is inserted into the inside of the anti-fog film roll, and the utility model is wrapped around the outer surface of the anti-fog film roll. The anti-fog film roll is supported and fixed by the expansion support device 2. Then, the closing plate 4 is placed at the open end of the utility model, and the anti-fog film roll is squeezed by the compression fixing device 3, thereby fixing the anti-fog film roll. This prevents the anti-fog film roll from loosening during transportation and can be used for anti-fog film rolls of different sizes.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
