Description

Technical Field

[0001] This utility model specifically relates to a plastic paper tube structure. Background Technology

[0002] Tissue paper is an everyday consumable, and tissue boxes are containers used to store tissues. They are typically provided in homes, upscale hotels, office buildings, parks, and other public places. These tissues are usually rolls, rotated within a tissue box for users to pull out. However, sometimes when pulling out the tissue, the force applied is too great, and the roll continues to rotate due to inertia after stopping, resulting in the pulled-out length exceeding the actual usable length. Current designs lack convenient ways to collect the excess tissue, which often hangs outside the tissue box, easily becoming dirty or wet and eventually discarded, leading to waste. Utility Model Content

[0003] In view of the defects of the existing technology, the technical problem to be solved by this utility model is to provide a plastic paper tube structure.

[0004] A plastic paper tube structure includes a tube body with an open mounting cavity at one end. A tube cover is detachably connected to the opening of the mounting cavity. A paper outlet is axially extending through one side of the tube body. A placement rod is rotatably disposed at the center of the mounting cavity. One end of the placement rod extends through the tube body to the outside of the tube body. The placement rod has a cavity axially disposed inside. A through hole communicating with the cavity is provided around the placement rod. A clamping member is movably disposed in the cavity and can protrude outward through the through hole to the outside of the placement rod. A driving member is provided in the cavity to drive the clamping member to maintain its convex outward connection to the outside of the placement rod.

[0005] In one embodiment, the placement rod is provided with a circular connecting plate, and the outer periphery of the circular connecting plate is recessed with a first limiting groove along the circumference. The side wall of the cylinder is provided with a first threaded hole through the first limiting groove along the circumference. A limiting member is inserted into the first threaded hole, and one end of the limiting member extends into the first limiting groove.

[0006] In one embodiment, the driving member is a column that is movably inserted into the cavity, and the end of the column near the clamping member is an arc surface.

[0007] In one embodiment, a second screw hole is recessed at the center of one side of the annular connecting plate. The second screw hole is threadedly connected to a limiting collar. One end of the driving member extends through the cavity to the inner ring of the limiting collar and is provided with a first guide flange. A spring abuts against the first guide flange and the annular connecting plate.

[0008] In one embodiment, the driving member has a second limiting groove recessed on both sides along its axial direction, and the cavity is provided with a second guide flange that cooperates with the second limiting groove.

[0009] In one embodiment, the clamping member is rotatably disposed within the through hole, and a torsion spring is provided at the rotatable connection between the clamping member and the through hole. The torsion spring ensures that the clamping member is kept in a retracted state within the cavity. When the clamping member is in its initial state without external force, the length direction of the clamping member is inclined at an angle to the axial direction of the placement rod.

[0010] In one embodiment, the diameter of the placement rod is less than or equal to the outer diameter of the inner tube of the paper roll.

[0011] In one embodiment, the outer periphery of the annular connecting plate is provided with a sealing ring that can abut against the inner wall of the mounting cavity.

[0012] In summary, the advantages of this utility model over the prior art are:

[0013] This invention utilizes a rotating placement rod located at the center of the mounting cavity. This allows the paper roll to be directly fitted onto the placement rod, enabling it to rotate freely relative to the rod when pulled. This effectively reduces resistance during paper feeding, significantly improving the smoothness and user experience of pulling the paper roll. Furthermore, the cavity, perforation, clamping element, and driving element within the placement rod constitute a unique paper receiving mechanism. When paper needs to be received, simply press the driving element. The driving element causes the clamping element to protrude outward through the perforation onto the outside of the placement rod. The clamping element makes close contact with the inner wall of the paper roll, increasing the friction between the placement rod and the paper roll. Rotating the placement rod then rotates the paper roll to achieve the receiving operation, eliminating the need for manual winding. This simple and convenient operation significantly improves the efficiency of paper roll storage and organization. Attached Figure Description

[0015] Figure 2 This is a perspective view of a plastic paper tube structure in one embodiment of the present invention. Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0017] like Figures 1 to 2The present invention preferably provides a plastic paper tube structure, including a tube body 1, the tube body 1 having an installation cavity 2 with one end open, a tube cover 3 detachably connected to the opening of the installation cavity 2, a paper outlet 4 extending through the tube body 1 along its axial direction on one side, a placement rod 5 rotatably disposed at the center of the installation cavity 2, one end of the placement rod 5 extending through the tube body 1 to the outside of the tube body 1, a cavity 6 disposed along its axial direction in the placement rod 5, a through hole 7 communicating with the cavity 6 on the periphery of the placement rod 5, a clamping member 8 movably disposed in the cavity 6 and able to protrude outward from the outside of the placement rod 5 through the through hole 7, and a driving member 9 disposed in the cavity 6 to drive the clamping member 8 to remain in a connected state protruding outward from the outside of the placement rod 5.

[0018] Specifically, by rotating a placement rod at the center of the mounting cavity, the paper roll can be directly fitted onto the placement rod. When pulled, the paper roll can rotate freely relative to the placement rod, effectively reducing resistance during the paper feeding process and greatly improving the smoothness and user experience of pulling the paper roll. Secondly, the cavity, perforation, clamping element, and driving element within the placement rod constitute a unique paper receiving mechanism. When paper needs to be received, simply press the driving element. The driving element causes the clamping element to protrude outward through the perforation onto the outside of the placement rod. The clamping element makes close contact with the inner wall of the paper roll, increasing the friction between the placement rod and the paper roll. Rotating the placement rod then rotates the paper roll to achieve the paper receiving operation, eliminating the need for manual winding. This simple and convenient operation significantly improves the efficiency of paper roll storage and organization.

[0019] In summary, this application differs significantly from existing technologies (which achieve paper feeding by using a placement rod to maintain frictional contact and locking with the inner side of the paper roll). In the aforementioned existing technologies, when the paper roll is pulled during feeding, the frictional force between the placement rod and the inner roll is difficult to control precisely. Excessive friction can easily lead to difficulty in pulling the paper roll, resulting in a poor user experience.

[0020] Furthermore, the placement rod 5 is provided with an annular connecting plate 10. A first limiting groove 11 is recessed along the circumference of the outer periphery of the annular connecting plate 10. A first threaded hole 12 is provided through the side wall of the cylinder 1 along the circumference corresponding to the first limiting groove 11. A limiting component is threaded into the first threaded hole 12, with one end extending into the first limiting groove 11. Specifically, the limiting component cooperates with the first limiting groove to achieve the rotational installation of the placement rod within the cylinder, ensuring the stability and reliability of the placement rod installation.

[0021] Furthermore, the driving component 9 is a column that is movably inserted into the cavity 6, and the end of the column near the clamping component 8 has an arc surface. Thus, when the user presses the driving component, the arc surface abuts against the clamping component, thereby avoiding damage to the clamping component when pressing against it.

[0022] Furthermore, a second screw hole 13 is recessed at the center of one side of the annular connecting plate 10. The second screw hole 13 is threadedly connected to a limiting collar 14. One end of the driving member 9 extends through the cavity 6 to the inner ring of the limiting collar 14 and is provided with a first guide flange 15. A spring 16 abuts between the first guide flange 15 and the annular connecting plate 10.

[0023] Furthermore, the driving member 9 has a second limiting groove 17 recessed on both sides along its axial direction, and the cavity 6 is provided with a second guide flange 18 that cooperates with the second limiting groove 17.

[0024] Furthermore, the clamping member 8 is rotatably disposed within the through hole 7, and a torsion spring (not shown in the figure) is provided at the rotatable connection between the clamping member 8 and the through hole 7. The torsion spring (not shown in the figure) ensures that the clamping member 8 remains in a retracted state within the cavity 6. When the clamping member 8 is in its initial state without external force, its length direction is inclined at an angle to the axis of the placement rod 5. Thus, the rotatable clamping member, combined with the torsion spring design, allows the clamping member to automatically retract into the cavity when no external force is applied, avoiding interference with the normal paper feeding of the roll, further optimizing the overall performance and user experience of the plastic paper roll.

[0025] Furthermore, the diameter of the placement rod 5 is less than or equal to the outer diameter of the inner tube of the paper roll. This ensures that the paper roll can be smoothly fitted onto the placement rod, and that the paper roll can rotate freely relative to the placement rod when pulled, effectively reducing resistance during the paper feeding process and greatly improving the smoothness of pulling the paper roll and the user experience.

[0026] Furthermore, the outer periphery of the annular connecting plate 10 is provided with a sealing ring (not shown in the figure) that can abut against the inner wall of the mounting cavity 2.

[0027] In summary, when paper needs to be fed, the paper roll is placed on the placement rod. Under the pulling force, the paper roll rotates relative to the placement rod. Since the retaining member is housed in the cavity under the action of the torsion spring, it does not obstruct the rotation of the paper roll, thus achieving smooth paper feeding. When paper needs to be retracted, the user presses the drive component extending to the end of the placement rod on the outside of the tube, causing the drive component to move towards the retaining member. The arc surface of the drive component pushes the retaining member to overcome the resistance of the torsion spring, protruding outward through the perforation from the outside of the placement rod and making close contact with the inner wall of the paper roll tube, increasing the friction between the placement rod and the paper roll, thereby rotating the placement rod to achieve the paper retraction operation. After releasing the placement rod, under the elastic force of the spring, the drive component returns to its original position, and the retaining member is housed back in the cavity under the action of the torsion spring, restoring the initial paper feeding state.
