Description

Technical Field

[0001] The utility model relates to the technical field of paper tubes, in particular to a new type of wear-resistant paper tube. Background Art

[0002] A paper tube refers to a tubular object processed from paper. It is widely used in the carrying and packaging of various films and can also be used for protective packaging of items. During transportation or storage, there are more or less situations where friction and extrusion occur between the outer periphery and the ends of the existing paper tubes. Since the paper tube is formed by paper layer processing, its wear resistance is limited. When it is excessively pressed and worn, its service quality is affected. Therefore, we propose a new type of wear-resistant paper tube. Content of the Utility Model

[0003] The utility model mainly solves the technical problems existing in the above-mentioned prior art, and provides a new type of wear-resistant paper tube.

[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme. A new type of wear-resistant paper tube includes a sealing end and a protective inner sleeve integrally formed with the sealing end. A paper tube is wound and formed outside the protective inner sleeve. A protective outer sleeve is sleeved outside the paper tube. A buffer gasket is arranged inside the protective outer sleeve. The inner side of the protective outer sleeve is in mutual fitting cooperation with the outside of the paper tube through the buffer gasket. The other end of the protective inner sleeve is provided with a sealing cover for sealing and cooperating with the paper tube.

[0005] Preferably, a docking hole is opened at the bottom of the protective outer sleeve, and a limiting shaft that fits with the docking hole is installed at the top of the sealing end. The bottom of the protective outer sleeve is mutually sleeved and cooperated with the limiting shaft at the top of the sealing end through the docking hole.

[0006] Preferably, a connecting end is installed at the bottom of the sealing cover. The connecting end is of a ring structure. A threaded groove is opened at the end of the protective inner sleeve. Connecting threads are opened on both the inner and outer sides of the connecting end. The bottom of the sealing cover is threadedly connected and cooperated with the threaded groove at the end of the protective inner sleeve through the connecting threads on both the inner and outer sides of the connecting end.

[0007] Preferably, a docking washer that is sleeved outside the limiting shaft is arranged above the sealing end, and a sealing gasket is arranged at the bottom of the sealing cover. Both the sealing gasket and the docking washer have deformation characteristics.

[0008] Preferably, after the sealing cover is threadedly connected to the inside of the threaded groove through the connecting end, the sealing cover is in a sealed and fitting state with the protective inner sleeve, the paper tube, and the protective outer sleeve.

[0009] The utility model provides a new type of wear-resistant paper tube, which has the following beneficial effects:

[0010] 1. A novel wear-resistant paper tube. In this article, the paper tube can be formed by winding around the periphery of a protective inner sleeve, and a protective outer sleeve is sleeved and wrapped around the outside of the paper tube. The protective outer sleeve can protect the periphery of the paper tube, while the protective inner sleeve can protect the inside of the paper tube. An encapsulation cover is provided at the upper end of the protective inner sleeve. After the encapsulation cover is threadedly connected to the inside and outside of the connecting end with the internal thread in the thread groove, it can encapsulate and protect the upper end of the paper tube. Similarly for the encapsulation end. In this way, the inside, outside and ends of the paper tube can all be protected, reducing the wear on the paper tube caused by the external environment, thereby achieving the effect of avoiding damage to the paper tube caused by external pressure and improving the use quality of the paper tube.

[0011] 2. A novel wear-resistant paper tube. A docking washer that forms a socket connection with the outside of the protective inner sleeve is provided above the encapsulation end, and an encapsulation pad is provided below the encapsulation cover. The encapsulation pad and the docking washer both have deformation characteristics. When the paper tubes are docked and installed, the encapsulation pad and the docking washer can both form encapsulation protection for the ends of the paper tubes. Similarly for the buffer gasket inside the protective outer sleeve, thereby achieving the effect of improving the sealing and waterproof effect of the paper tube itself.
