Description

Technical Field

[0001] This utility model relates to the field of paper tube technology, and in particular to a pressure-resistant large-diameter paper tube. Background Technology

[0002] Paper tubes are tubular objects made of paper products. With the development of the paper products industry, there are more and more varieties of paper tubes, and their uses are becoming more and more widespread. For example, paper tubes are used for calligraphy and paintings or for rolling up packaging bags.

[0003] Currently, in order to meet the needs of paper tubes, large-diameter paper tubes have emerged. Some large-diameter paper tubes are made of one or more layers of paper products. Large-diameter paper tubes have poor overall compressive strength and are prone to flattening or collapse when subjected to external forces. Therefore, we propose a pressure-resistant large-diameter paper tube. Utility Model Content

[0004] The purpose of this utility model is to provide a pressure-resistant large-diameter paper tube. By setting up a pressure-resistant structure, the support component and the pressure-resistant ring can be easily connected by a snap-fit ​​assembly. Then, by using the cooperation of the pressure-resistant ring, the arc-shaped support plate, the reinforcing ribs and the reinforcing plate, the external force can be borne, thereby giving the entire large-diameter paper tube good pressure resistance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pressure-resistant large-diameter paper tube, comprising an outer tube, wherein a pressure-resistant structure is provided on the inner side of the outer tube, the pressure-resistant structure comprising:

[0006] Pressure-resistant ring, the pressure-resistant ring is connected to the inside of the outer tube;

[0007] The support assembly is connected to the middle of the pressure-resistant ring. The pressure-resistant ring and the support assembly work together to support the outer tube.

[0008] A snap-fit ​​assembly is provided between the pressure-resistant ring and the support assembly, and the snap-fit ​​assembly is used to connect the pressure-resistant ring and the support assembly;

[0009] A filling layer is fixedly connected to the inner wall of the outer tube, and the filling layer is used to support the outer tube.

[0010] Preferably, the support assembly includes an arc-shaped support plate, a reinforcing plate located on one side of the arc-shaped support plate, and a plurality of reinforcing ribs fixedly connected between the arc-shaped support plate and the reinforcing plate.

[0011] Preferably, the snap-fit ​​assembly includes a snap-fit ​​groove formed in the middle of the pressure-resistant ring, a through groove formed on one side of the snap-fit ​​groove, and two limiting sleeves fixedly connected inside the snap-fit ​​groove.

[0012] Preferably, both limiting sleeves are made of rubber, and one side of the limiting sleeve has an arc-shaped groove, and the inside of the arc-shaped groove is engaged with one side of the arc-shaped support plate.

[0013] Preferably, the number of the compression rings is set to multiple, and a filling layer is provided between each pair of adjacent compression rings. The filling layer is made of corrugated board and is located on the outside of the arc-shaped support plate.

[0014] Preferably, the number of the support components is at least four, and both the compression ring and the support components are made of stainless steel or plastic.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] By using snap-fit ​​components to connect the support components and the pressure-resistant ring, the support components and the pressure-resistant ring are assembled. When the large-diameter paper tube is subjected to external forces, the support components and the pressure-resistant ring can bear the external forces, thus preventing the outer tube from being directly squeezed flat or collapsing significantly. At the same time, the filling layer can further fill the gap between the outer tube and the support components, thereby supporting the outer tube and improving the local pressure resistance of the outer tube. This design, by setting up a pressure-resistant structure, facilitates the connection of the support components and the pressure-resistant ring using snap-fit ​​components. Then, by using the cooperation of the pressure-resistant ring, the arc-shaped support plate, the reinforcing ribs, and the reinforcing plate, the external forces are borne, thus giving the entire large-diameter paper tube good pressure resistance.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides, for example Figure 1-4 The diagram shows a pressure-resistant large-diameter paper tube, comprising an outer tube 1, with a pressure-resistant structure on the inner side of the outer tube 1. The pressure-resistant structure includes: a pressure-resistant ring 3 connected to the inside of the outer tube 1; a support component 4 connected to the middle of the pressure-resistant ring 3, the pressure-resistant ring 3 and the support component 4 cooperating to support the outer tube 1; a snap-fit ​​component 5 provided between the pressure-resistant ring 3 and the support component 4, the snap-fit ​​component 5 being used to connect the pressure-resistant ring 3 and the support component 4; and a filling layer 2, the inner wall surface of the outer tube 1 being fixedly connected with a filling layer. The filling layer 2 is used to support the outer tube 1. The support component 4 and the anti-compression ring 3 are connected by the snap-fit ​​component 5, thereby assembling the support component 4 and the anti-compression ring 3. When the entire large-diameter paper tube is subjected to external force, the support component 4 and the anti-compression ring 3 can bear the external force, thereby preventing the outer tube 1 from being directly squeezed flat by external force or from collapsing significantly. At the same time, the filling layer 2 can further fill the gap between the outer tube 1 and the support component 4, thereby supporting the outer tube 1 and improving the local pressure resistance of the outer tube 1.

[0024] It should be further explained that the number of support components 4 is set to at least four. Both the pressure-resistant ring 3 and the support components 4 are made of stainless steel or plastic. The fact that both the pressure-resistant ring 3 and the support components 4 are made of stainless steel or high-strength plastic can utilize the strength of stainless steel or high-strength materials to make the pressure-resistant structure have good pressure-bearing capacity, thereby improving the pressure resistance of the entire large-diameter paper tube.

[0025] Furthermore, the support assembly 4 includes an arc-shaped support plate 401, a reinforcing plate 403 located on one side of the arc-shaped support plate 401, and multiple reinforcing ribs 402 fixedly connected between the arc-shaped support plate 401 and the reinforcing plate 403. Through the cooperation of the arc-shaped support plate 401 and the pressure-resistant ring 3, the external force is borne, thereby preventing the large-diameter paper tube from being damaged under external force. At the same time, the cooperation of the reinforcing ribs 402 and the reinforcing plate 403 can better prevent the arc-shaped support plate 401 from being directly squeezed and deformed by external force, thereby giving the support assembly 4 better structural stability and further improving the pressure resistance of the entire large-diameter paper tube.

[0026] Furthermore, the snap-fit ​​assembly 5 includes a snap-fit ​​groove 501 formed in the middle of the pressure-resistant ring 3, a through groove 502 formed on one side of the snap-fit ​​groove 501, and two limiting sleeves 503 fixedly connected inside the snap-fit ​​groove 501. Both limiting sleeves 503 are made of rubber, and one side of the limiting sleeve 503 has an arc-shaped groove, and the inside of the arc-shaped groove snaps into one side of the arc-shaped support plate 401. When it is necessary to connect the support assembly 4 to the pressure-resistant ring 3, the arc-shaped support plate 401 is inserted into the snap-fit ​​groove 501, and the reinforcing rib 402 passes through the through groove 502. The arc-shaped support plate 401 is used to compress the limiting sleeve 503. The interference fit between the arc-shaped support plate 401 and the limiting sleeve 503 compresses the limiting sleeve 503, thereby fixing the arc-shaped support plate 401 with the limiting sleeve 503.

[0027] Furthermore, the number of pressure-resistant rings 3 is set to multiple, and a filling layer 2 is provided between each two adjacent pressure-resistant rings 3. The filling layer 2 is made of corrugated board and is located on the outside of the arc-shaped support plate 401. The filling layer 2 is fixedly connected to the inner wall of the outer tube 1. The filling layer 2 made of corrugated board can fill the gap between the outer tube 1 and the arc-shaped support plate 401, thereby supporting the interior of the outer tube 1 and further improving the pressure resistance of the entire outer tube 1.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
