[0002] Chemical fiber paper tubes are usually used in applications that need to withstand relatively high pressure and weight, such as industrial pipelines, oil and gas pipelines, building supports, etc. These paper tubes are usually made of multiple layers of cellulose pulp and are specially treated to improve their strength and pressure resistance. Glass fibers are added to the paper pulp of the paper tubes, and the use of carbon fibers makes the paper tubes more solid and durable, suitable for applications that require extremely high strength.

[0003] In the patent with the publication number CN217837949U, a high-strength and pressure-resistant chemical fiber paper tube is disclosed, which includes a chemical fiber paper tube body. An anti-pressure structure is arranged inside the chemical fiber paper tube body. The anti-pressure structure includes a first end anti-pressure ring, a middle anti-pressure ring, a second end anti-pressure ring, an anti-pressure bracket and a tightening end. The first end anti-pressure ring is fixedly installed inside the chemical fiber paper tube body, and the middle anti-pressure ring is arranged on one side of the first end anti-pressure ring inside the chemical fiber paper tube body.

[0004] In the above technology, a bundling rope is embedded in the bundling groove of the tightening end in a circle for knotting, which can improve the phenomenon that it is inconvenient to tighten due to the smooth surface of the chemical fiber paper tube body. However, the bundling groove has a certain width, so the bundling rope is easy to move back and forth in the bundling groove, and long-term friction may damage the surface of the rope, which may cause uneven force distribution at the bundling part, which may cause the rope to bear a greater tensile force, thus affecting the bundling effect and durability. Therefore, innovation is made on this technology. Content of the Utility Model

[0005] The purpose of the utility model is to provide a high-strength and pressure-resistant chemical fiber paper tube to solve the problem that may cause uneven force distribution at the bundling part, which may cause the rope to bear a greater tensile force, thus affecting the bundling effect and durability as mentioned in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical scheme: a high-strength and pressure-resistant chemical fiber paper tube, which includes a chemical fiber paper tube body.

Protective sleeves are sleeved on both ends of the chemical fiber paper tube body. Two twisting shafts are arranged on one side of each of the two protective sleeves. L-shaped plates are sleeved on one end of each of the four twisting shafts. Pressing rings are sleeved on the other end of each of the two anti-pressure rings. First arc-shaped blocks are arranged on both sides of each of the two bundling rings. Second arc-shaped blocks are arranged on both sides of each of the two pressing rings. Straight rods are inserted and connected on one side of each of the four first arc-shaped blocks. Positioning strips are arranged on the top of each of the four first arc-shaped blocks.

[0007] As a preferred technical solution of the present utility model, one end of each of two adjacent straight rods is fixedly connected to one side of four second arc-shaped blocks respectively, and a plurality of concave holes are formed at the top ends of the four straight rods, and the positions of two adjacent positioning strips are corresponding to each other.

[0008] As a preferred technical solution of the present utility model, one end of each of the four positioning strips is threadedly connected to the inside of a plurality of concave holes, and the positions of the plurality of concave holes are arranged at equal intervals.

[0009] As a preferred technical solution of the present utility model, one side of each of the four second arc-shaped blocks is fixedly connected to both sides of two pressing rings respectively, and the two pressing rings are movably sleeved on the other ends of two compression rings respectively.

[0010] As a preferred technical solution of the present utility model, the diameters of the two pressing rings are both larger than the diameters of the two compression rings.

[0011] As a preferred technical solution of the present utility model, a rotating shaft is fixedly installed at one end of each of the four straight rods, and the four straight rods are movably inserted through one side of four first arc-shaped blocks respectively.

[0012] As a preferred technical solution of the present utility model, the diameters of the four rotating shafts are all larger than the diameters of the four straight rods.

Insert one end of the positioning strip 11 into the internal concave hole 10 in sequence, and the two are threadedly connected, so that the first arc-shaped block 6 and the straight rod 9 can be limited and fixed.

[0025] Embodiment 2:

[0026] On the basis of Embodiment 1, as Figure 1 and Figure 4 shown, one side of each of the four second arc-shaped blocks 8 is fixedly connected to both sides of each of the two compression rings 7. The two compression rings 7 are movably sleeved on the other end of each of the two compression rings 2. Rotating shafts 12 are fixedly installed at one end of each of the four straight rods 9. The four straight rods 9 are movably inserted and connected to one side of each of the four first arc-shaped blocks 6. For a high-strength pressure-resistant chemical fiber paper tube of the present utility model, by providing the protective sleeve 3, the torsion shaft 4, the L-shaped plate 5 and the concave hole 10, the L-shaped plate 5 and the torsion shaft 4 are fixedly sleeved, and they are respectively arranged on both sides of the protective sleeve 3, so that both sides of the chemical fiber paper tube body 1 can be supported to make it more firm. The equally spaced concave holes 10 can adjust the area where the compression ring 7 moves at one end of the compression ring 2.

[0027] Working principle: Chemical fiber paper tubes are usually used in applications that need to withstand high pressure and weight. These paper tubes are usually made of multiple layers of cellulose pulp and are specially treated to improve their strength and pressure resistance. Glass fibers are added to the paper pulp of the paper tube, and the use of carbon fibers makes the paper tube stronger and more durable, suitable for applications that require extremely high strength. Existing chemical fiber paper tubes generally need to be stacked and tied with ropes during transfer and transportation. The ropes are tied between the compression ring 2 and the chemical fiber paper tube body 1. To ensure the stability of the ropes, when tying the ropes, the staff can move two straight rods 9 left and right in sequence, which will drive the pressing ring 7 to move at one end of the compression ring 2, so as to adjust the distance between the pressing ring 7 and the tightening ring 13, and can abut against the tying ropes, making the tying ropes more secure in the tightening groove. One end of the positioning bar 11 is sequentially inserted into the internal of the concave hole 10, and the two are threadedly connected, so as to limit and fix the first arc-shaped block 6 and the straight rod 9, ensuring the stability of the pressing ring 7. The L-shaped plate 5 and the twisting shaft 4 are fixedly sleeved, and are respectively arranged on both sides of the protective sleeve 3, so as to support both sides of the chemical fiber paper tube body 1 and make it more firm. The equally spaced concave holes 10 can adjust the area where the pressing ring 7 moves at one end of the compression ring 2. The straight rod 9 can movably penetrate through one side of the first arc-shaped block 6. The compression ring 2 is made of carbon fiber composite material, has good compression resistance, and has the characteristics of high strength and pressure resistance.
