[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0020] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0021] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present invention provides a pearl cotton packaging corner protector with a cushioning and reinforcing structure, comprising an inner tube 5 and a sheath 1. One end of the sheath 1 is open, and the center of the other end is provided with a through hole. The sheath 1 is sleeved on one end of the inner tube 5 through the through hole. One end of the inner tube 5 protrudes to form multiple pressure-bearing parts 2. The multiple pressure-bearing parts 2 are evenly distributed in a ring structure. A gap 3 is formed between the pressure-bearing parts 2 to allow the pressure-bearing parts 2 to expand outward. The interior of the multiple pressure-bearing parts 2 is combined to form a conical pressure channel. The interior of the inner tube 5 is provided with a compression column 14. One end of the compression column 14 extends into the pressure channel and forms a conical compression part. One end of the inner tube 5 is threadedly connected to a pressure ring 9 to press the sheath 1 tightly.

[0023] In this embodiment, a fixing plate 8 is installed in the opening at the end of the inner tube 5 away from the pressure part 2. A sealing bearing is installed at the center of the fixing plate 8. A screw hole penetrating the extrusion column 14 is provided at the center of the extrusion column 14. A screw 13 is installed in the inner ring of the sealing bearing. One end of the screw 13 is threaded into the screw hole, and a handwheel 7 is installed at the other end.

[0024] In this embodiment, a positioning groove 6 is provided axially on the outer wall surface of the inner tube 5, and a positioning part 12 is formed by protruding from the outer wall surface of the extrusion column 14 opposite to the positioning groove 6. The positioning part 12 is slidably disposed in the positioning groove 6. The extrusion column can be positioned by the positioning part and the positioning groove, so that the extrusion column can only move back and forth along the positioning groove.

[0025] In this embodiment, the inner side of the sheath 1 is recessed outside the through hole to form a ring-shaped limiting groove. The outer wall of the inner tube 5 is directly opposite the limiting groove and a limiting ring 11 is installed. The limiting ring 11 is inserted into the limiting groove, and the sheath 1 is pressed and fixed by the limiting ring 11 and the pressure ring 9.

[0026] In this embodiment, multiple gripping rods 10 are installed in a ring structure on the outer ring surface of the pressure ring 9. The gripping rods facilitate the rotation of the pressure ring, allowing the pressure ring to move along the thread until the sheath is pressed tightly onto the limiting ring.

[0027] Conversely, after the pressure ring is removed from the inner tube, the sheath can also be removed from the inner tube, making it easy to replace. The inner tube can be used continuously and repeatedly, increasing its service life and reducing costs.

[0028] In this embodiment, the sheath 1 is made of pearl cotton material, and multiple ring-shaped reinforcing parts 4 are protruding on the outer ring surface of the sheath 1. The thickness of the outer part of the sheath is increased by the reinforcing parts, thereby increasing the protective effect.

[0029] In this embodiment, the pressure-bearing part 2 and the inner tube 5 are integrally injection molded. The pressure-bearing part 2 and the inner tube 5 are made of spring steel, which increases the strength and service life of the inner tube. Moreover, after being squeezed by the extrusion column, the pressure-bearing part can be smoothly expanded outward through its elasticity.

[0030] In use, the inner tube can be inserted into the core of the protective film, and the screw is rotated by handwheel. The screw's movement drives the extrusion column, which moves along the positioning groove. The movement of the extrusion column drives the extrusion part, which pushes the pressure-bearing part outward, causing it to expand outward and press against the inner wall of the core. The clamping force between the extrusion part and the core increases the stability of the sheath at both ends of the protective film, greatly reducing the probability of it falling off.

[0031] As the inner tube is inserted into place, the sheath can be smoothly fitted onto both ends of the protective film. The sheath protects both ends of the protective film, and because it is made of pearl cotton, it is flexible and can provide cushioning protection.

[0032] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
