Description

Technical Field

[0001] This utility model relates to the field of cat climbing frame technology, specifically a high anti-slip spiral core paper tube. Background Technology

[0002] Cats are a very popular pet. They are naturally lively and active and love to climb. To prevent them from damaging furniture, people prepare all sorts of items for their pets. Among these, cat trees are a common type of pet tree. They are usually multi-tiered and their main function is to provide pets with a space to play, exercise, and rest.

[0003] Most cat tree frames are made of paper tubes, but the current paper tube frames have some shortcomings. As a frame, the paper tube needs to have a certain compressive strength to prevent it from being squeezed or tangled and deformed. The existing paper tubes have poor compressive strength and are prone to deformation, which affects their use. In addition, because cats love to climb and pull, the yarn wrapped around the outside of the paper tube slips down. The current paper tubes are too smooth, which makes the yarn easy to fall off and not secure.

[0004] Utility model patent application number 202420879513.3 discloses a spiral paper tube for winding cores, which includes an inner cylinder and an outer cylinder. The outer cylinder is wrapped around the outer side of the inner cylinder in a multi-layer spiral winding manner, with layers arranged at the edge of the outer cylinder. Anti-slip stripes are distributed circumferentially on the outer cylinder and extend axially. A circumferential limiting component and an axial limiting component are provided between the inner cylinder and the outer cylinder. However, the applicant found that this design still has the following technical problems: 1. The core design of the paper tube is not stable and is prone to deformation during winding; 2. The outer anti-slip stripes are not convenient for winding yarn, and the vertical stripes still easily cause the yarn to slip and fall off; 3. Its length adjustment is limited, and the height cannot be adjusted according to needs. Utility Model Content

[0005] To address the above problems, this utility model provides a highly anti-slip spiral paper tube for core winding. By improving upon existing methods, it makes the paper tube support for cat climbing frames more durable and reliable.

[0006] The technical solution for a high-anti-slip spiral paper tube provided in this application is as follows:

[0007] A high-slip spiral paper tube for winding cores includes: a paper tube body;

[0008] The paper tube body includes an outer layer, a reinforcing layer, an inner layer, and a plastic layer. The reinforcing layer is located between the outer layer and the inner layer. The outer wall of the reinforcing layer is bonded to the inner wall of the outer layer, the inner wall of the reinforcing layer is bonded to the outer wall of the inner layer, and the inner wall of the inner layer is bonded to the outer wall of the plastic layer. The upper and lower ends of the inner wall of the plastic layer are provided with threads.

[0009] As an improvement, the paper tube body also includes a threaded tube, one end of which is connected to the thread at one end of the inner wall of the plastic layer, and multiple paper tube bodies can be connected end to end through the threaded tube.

[0010] As an improvement, a waterproof membrane is provided on both the outer wall of the outer layer and the inner wall of the inner layer.

[0011] As an improvement, the annular cross-section of the reinforcing layer is arranged in a series of V-shaped edges connected end to end.

[0012] As an improvement, an anti-slip layer is also provided on the outer side of the outer layer. The surface of the anti-slip layer is rough and friction-prone, and the anti-slip layer is spirally wrapped around the outer side of the outer layer.

[0013] As an improvement, the inner wall of the inner layer is provided with several ring-shaped protrusions, which are arranged around the axis of the inner layer and are equidistantly arranged along the axis of the inner layer.

[0014] As an improvement, the outer wall of the plastic layer is provided with several annular grooves, which are matched one-to-one with the annular protrusions.

[0015] As an improvement, the upper and lower ends of the paper tube body are also provided with annular bases, which are used to cover the internal structure of the paper tube body.

[0016] The beneficial effects of this utility model are as follows:

[0017] (1) The paper tube for high anti-slip spiral core of this utility model can play a basic fixing role through the innermost hard plastic layer, making its axial position more stable. On this basis, a reinforcement layer is also set. Multiple V-shaped edges on the reinforcement layer make the circumferential position more stable, not easy to deform, and the overall pressure resistance is stronger, making it more reassuring to use.

[0018] (2) This utility model improves the outer layer structure by setting an anti-slip layer on the outer side of the outer layer and using a frosted material to make its surface rough and friction-setting. During the process of yarn winding, the yarn can be stuck by the rough surface of the paper tube, making it more secure. With this design, it is not easy to fall off no matter how the cat scratches or climbs.

[0019] (3) This utility model improves the structure of the plastic layer by providing threads at both the upper and lower ends of the inner wall of the plastic layer. These threads can be connected with the threaded tube to combine multiple paper tube bodies together, and can be stacked according to the length requirements.

[0020] In summary, the advantages of this high-anti-slip spiral paper tube design compared to existing technologies are as follows: the plastic layer and reinforcing layer in the paper tube body ensure the stability of the paper tube body; the threaded design in the plastic layer facilitates flexible assembly and disassembly; and the outer anti-slip layer ensures that the yarn wrapped around it is more secure and does not fall off, making it more stable in use.

[0035] Example 1:

[0036] like Figures 1 to 9 As shown, a high-slip spiral core paper tube includes a paper tube body;

[0037] The paper tube body V includes an outer layer 1, a reinforcing layer 2, an inner layer 3, and a plastic layer 4. The reinforcing layer 2 is located between the outer layer 1 and the inner layer 3. The outer wall of the reinforcing layer 2 is bonded to the inner wall of the outer layer 1, and the inner wall of the reinforcing layer 2 is bonded to the outer wall of the inner layer 3. The inner wall of the inner layer 3 is bonded to the outer wall of the plastic layer 4. The inner wall of the plastic layer 4 has threads 41 at both the upper and lower ends. The plastic layer 4 is made of plastic material, which has good water resistance, pressure resistance, toughness, and deformation resistance, so it is not easily deformed by the influence of the environment and external forces.

[0038] It should be noted that the thread 41 can be used as a connection port between the paper tube body V and the other parts of the cat climbing frame. The paper tube body V and the cat climbing frame parts can be quickly assembled and disassembled through the threaded connection.

[0039] Waterproof membranes are provided on the outer wall of the outer layer 1 and the inner wall of the inner layer 3. Both the outer layer 1 and the inner layer 3 are paper tubes with openings at both ends. PP film is applied to the inner and outer walls of the paper tubes to form waterproof membranes, which have good waterproof performance, aging resistance and chemical corrosion resistance.

[0040] The annular cross-section of the reinforcing layer 2 includes several V-shaped corners 21 connected end to end, and the reinforcing layer 2 is made of corrugated cardboard rolled into a tube shape.

[0041] An anti-slip layer 11 is also provided on the outer side of the outer layer 1. The surface of the anti-slip layer 11 is rough and friction-determined. The anti-slip layer 11 is spirally wrapped around the outer side of the outer layer 1. The anti-slip layer 11 is made of kraft paper. The surface of the kraft paper has a certain roughness and obvious fibrous feel. It has good tear resistance and durability, which is conducive to the winding and fixing of yarn.

[0042] The inner wall of the inner layer 3 is provided with several ring-shaped protrusions 31. The ring-shaped protrusions 31 are formed by the inner layer 3 when it is rolled and extruded by a cylindrical mold during the paper winding process. The ring-shaped protrusions 31 are arranged around the axis of the inner layer 3 and are equidistantly arranged along the axis of the inner layer 3.

[0043] The outer wall of the plastic layer 4 is provided with several annular grooves 42, which are formed by CNC milling. The annular grooves 42 are matched and engaged with the annular protrusions 31 one by one.

[0044] The upper and lower ends of the paper tube body V are also provided with annular bases 12. The annular bases 12 are used to cover the internal structure of the paper tube body V. Specifically, the annular bases 12 are connected to the paper tube body V by glue.

[0045] Example 2:

[0046] Referring to Example 1, the difference between Example 2 and Example 1 lies in the following:

[0047] like Figure 1 , Figure 2 , Figure 9 , Figure 10 As shown, the paper tube body V also includes a threaded tube 5, one end of which is connected to the thread 41 at one end of the inner wall of the plastic layer 4. Multiple paper tube bodies V can be connected end to end through the threaded tube 5.

[0048] It should be noted that when the length of the individual paper tube body V does not meet the usage standard, the ends of the paper tube body V are connected by the threaded tube 5 to meet the height setting of the cat climbing frame. At the same time, the threaded tube 5 ensures the strength of the connection between the ends of the paper tube body V.

[0049] Its working principle is as follows: When assembling the cat tree, the paper tube body V is fixed to the support through the threads 41 in the plastic layer 4 inside the paper tube body V. The paper tube body V forms a second fixing structure through several V-shaped edges 21 connected end to end in the reinforcing layer 2, which increases the load-bearing capacity of the paper tube body V and makes it less prone to deformation. In this way, the cat's activities are less likely to cause the paper tube body V to deform, and it is safer to use. The cat tree will not tip over due to the deformation of the paper tube body V. The paper tube body V can be combined and stacked through the threaded tube 5. After the assembly is completed, the yarn is wrapped around the anti-slip layer 11 on the outer layer 1. In this way, even if there are many cats and they are naughty, there is no need to worry. They can climb and hook the yarn wrapped around the anti-slip layer 11 without it falling off or sliding down. In addition, the paper tube body V has a waterproof membrane, which makes it less prone to moisture and more durable.

[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
