Description

Technical Field

[0001] The utility model relates to the technical field of fresh-keeping films, in particular to a detachable wrapping film tube structure. Background Art

[0002] Cling film is a plastic packaging product, usually made of ethylene as the masterbatch through polymerization reaction. Cling film can be divided into three categories: the first is polyethylene, abbreviated as PE; the second is polyvinyl chloride, abbreviated as PVC; the third is polyvinylidene chloride, abbreviated as PVDC. It is used in microwave food heating, refrigerator food storage, fresh and cooked food packaging or greenhouse covering, etc. It is widely used in family life, supermarkets, hotels and restaurants, and industrial production of food packaging. Cling film is usually rolled into a stretch film covered on a tube for storage. When taking the film, the stretch film (including the tube) needs to be rolled for use, which is difficult to roll.

This utility model relates to a plastic wrap mounting rack, comprising a support plate, with mounting blocks (a) and (b) provided at each end of the support plate, respectively. A hinge is provided between the mounting block (b) and the support rod, with bolts (a) extending through the hinge and extending to the mounting block (b) and the interior of the support plate, respectively. A mounting hole (b) is defined in the top of the support plate, and a cutting plate is provided on the rear side of the support plate. A bolt (b) extending through the mounting hole (b) and extending to the interior of the cutting plate is provided on the surface of the support plate, with serrations defined on the top of the cutting plate. A disadvantage of this technical solution is that the mounting ring is connected to the outer portion of the plastic wrap reel (tube structure) for access to the wrap film supported by the mounting rack. However, this requires an additional accessory (the mounting rack) for access, reducing the convenience and practicality of the plastic wrap.

[0004] In summary: stretch film has the disadvantages of being inconvenient to use and having low functionality, which reduces its practicality. Utility Model Content

[0005] The utility model aims to overcome the shortcomings of the existing technology such as the inconvenience of use of stretch film and the low functionality of the tube structure, resulting in poor overall practicality, and provides a detachable stretch film tube structure that improves the convenience of use of stretch film and enhances the functionality and overall practicality of the tube structure.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A detachable wrap film tube structure includes a tube shell, in which a rotating support tube, a base sleeve, an extension rod and a limit assembly are connected. The rotating support tube is movably connected to the tube shell through the limit assembly. One end of the rotating support tube is rotatably connected to the tube shell, and the other end of the rotating support tube is detachably connected to one end of the extension rod. The other end of the extension rod is detachably connected to one end of the base sleeve, and the other end of the base sleeve is movably connected to a fixed assembly.

[0008] The tube shell is a hollow tubular structure for winding the stretch film. The inside of the tube shell is supported by a rotating support tube. At the same time, the rotating support tube can be moved on the tube shell, so that the tube shell can be flexibly rotated to prevent the stretch film from contacting with the structure outside the tube shell to increase friction and affect the use; a limit assembly is connected to the tube shell to limit the position of the rotating support tube to prevent displacement during rotation and cause unsmooth use; a base sleeve and an extension rod are connected to the rotating support tube. The base sleeve with the extension rod can be detachable on the rotating support tube, so that the base sleeve can be detached and connected to the displacement extension rod through the extension rod. The tube shell is mounted on a rotating support tube to support or stand the tube shell. Furthermore, the extension rod is detachably connected to the base sleeve, allowing it to be mounted on the standing height to adjust the height of the stretch film and enhance the adaptability of its placement. The fixing assembly is connected to the base sleeve to ensure the stretch film is stably placed and provides stability during use. The rotating support tube, base sleeve, extension rod, limit assembly, and fixing assembly are all located within the tube shell and can be disassembled and stored for easy packaging and transportation. They can also be extended to support material discharge and facilitate flexible access to the stretch film. This achieves the effect of a detachable tube structure that can be stored and supported for overall packaging and transportation and for access to the stretch film, improving the efficiency of stretch film access, enhancing functionality, and providing operational flexibility and practicality.

[0009] Preferably, the limiting assembly includes a front limiting ring and a rear limiting ring, both of which are connected to the inner wall of the tube shell, a gap is left between the front limiting ring and the rear limiting ring and is provided as a limiting slide groove, the rotating support tube is connected with a slider, the rear limiting ring is provided with a connecting groove, the connecting groove is connected to the limiting slide groove, and the slider is adapted to the size of the limiting slide groove and the connecting groove. The front limiting ring in the limiting assembly is connected to the inner wall of the tube housing near the tube opening. The rear limiting ring is connected behind the front limiting ring and provides a protective gap with the front limiting ring. This gap is defined as a limiting chute. The rotating support tube is sleeved within the tube housing, with its outer surface contacting the inner walls of the front and rear limiting rings. A slider is connected to the rear surface of the rotating support tube. The slider rotates to find the connecting groove and then slides into the limiting chute. The connecting groove is a linear depression, while the limiting chute is a circular depression. Once the slider enters the limiting chute, it can rotate within it. This allows the tube housing to rotate within the limiting chute when the wrap film is removed, while preventing it from falling out of the tube housing when stored. The slider is slidably connected to the connecting groove and rotatably connected to the limiting chute. The rotating support tube is partially extended from the tube housing by the slider to connect to the vertical support portion (relative to the tube housing), thereby spacing the wrap film from the vertical support portion. This improves the stability of the rotating support while ensuring smooth removal. This achieves a stable structural connection, facilitates storage and assembly, and ensures smooth use of the wrap film.

[0010] Preferably, the stop assembly includes a retaining ring and an elastic member. The retaining ring is connected to the inner wall of the housing, and the elastic member is sleeved onto the base sleeve. One end of the elastic member is connected to the retaining ring, while the other end of the elastic member abuts against the rotating support tube. The retaining ring in the stop assembly is connected to the inner wall of the housing. The elastic member is a circular spring member connected to the retaining ring for support. The other end of the elastic member abuts against the rotating support tube through elastic force, preventing the slider from sliding out of the connecting groove during use. This further improves the structural connection and operational stability.

[0011] Preferably, the rotating support tube is provided with a placement hole, the base sleeve is plugged into the placement hole, the placement hole is provided with a socket and a positioning slot, the socket and the positioning slot are arranged relative to each other, and the extension rod is adapted to the size of the placement hole and the positioning slot. The rotating support tube is a hollow structure with an inner cavity set as a hole, and the base tube is sleeved in the placement hole and is attached to the inner wall of the rotating support tube to prevent it from falling out easily in the stored state, and it can be quickly pulled out when in use. At the same time, the inner wall of the placement hole is provided with a socket and relatively arranged positioning slots, so that after removing the rotating sleeve and the extension rod connected therein, the extension rod can be inserted into the socket and the positioning slot to form a vertical connection with the rotating support tube. The opening position of the positioning slot and the socket is at a certain distance from the port position of the tube shell to separate the extension rod and the tube shell, so that the wrapping film is easy to take out. The connection operation of the structure is simple and fast, and it is easy to use.

[0012] Preferably, one end of the base sleeve is provided with a slot with internal threads, and the extension rod is provided with external threads, which are threadedly connected to the slot. The base sleeve is threadedly connected to the extension rod via the slot, allowing for easy adjustment of the extension rod, thereby quickly adjusting the placement height of the stretch film. This facilitates adjustment of the stretch film's height and enhances its practicality.

[0013] Preferably, the other end of the base sleeve is provided with a movable groove, and the fixing assembly includes a suction cup and a connecting block. The movable groove is provided with a connecting groove, the connecting groove is provided with an internal thread, and the connecting block is provided with an external thread. One end of the connecting block is threadedly connected to the connecting groove, and the other end of the connecting block is connected to the suction cup. The base sleeve is provided with a suction cup through the movable groove, and the suction cup is fixed to the connecting block so that it is fixed in the movable groove through the connecting block. When supporting and fixing, the connecting groove is unscrewed, so that the connecting block can move the suction cup out of the movable groove for suction. At the same time, the connecting block is connected to the base sleeve through the connecting groove to increase the stability of the suction cup connection. This achieves the effect of convenient fixing and stable structural connection.

[0014] The beneficial effects of the utility model are: the detachable tube structure of the stretch film tube can be stored and supported to facilitate the overall packaging and transportation and the use of the stretch film; the efficiency of taking the stretch film is improved; the functionality is enhanced, the operation is flexible and practical; the stability of the structural connection is improved, the storage and assembly are convenient, and the smooth use of the stretch film is guaranteed; the operation is simple and quick.
