Description

Technical Field

[0001] The utility model relates to the technical field of paper tubes, in particular to a paper tube with an anti-extrusion structure inside. Background Art

[0002] A paper tube refers to a cylindrical paper tube used for storage. Since paper is an environmentally friendly material, it is deeply loved by users.

[0003] When the paper tube is in use, it is easy to be squeezed from the outside, which may damage the items stored inside, or it may be bumped during transportation, causing the internal items to hit the side wall and cause damage to the items. Utility Model Content

[0004] In order to overcome the above-mentioned defects existing in the prior art, the utility model provides a paper tube with an anti-squeezing structure inside.

[0005] The technical solution adopted by the utility model to solve the technical problem is: a paper tube with an anti-squeezing structure inside, comprising a paper tube, a paper tube hollow part is arranged on the inner side of the paper tube, a plurality of groups of first springs are fixedly installed on the inner wall of the paper tube hollow part, a buffer arc plate is fixedly installed on the inner side of the first spring, and a plurality of groups of the buffer arc plates are fixedly installed at equal distances inside the paper tube hollow part.

[0006] Furthermore, a paper tube outer wall is arranged on the outer side of the paper tube, and a paper tube inner wall is arranged on the inner side of the paper tube.

[0007] Furthermore, an annular groove is provided between the outer wall of the paper tube and the inner wall of the paper tube, and a corrugated connecting plate is provided in the annular groove.

[0008] Furthermore, a plurality of groups of second springs are fixedly mounted on the bottom of the hollow portion of the paper tube, the telescopic ends of the second springs are fixedly mounted on a bottom plate, and the bottom plate is slidably mounted inside the hollow portion of the paper tube.

[0009] The beneficial effect of the utility model is that by placing the items to be stored inside the hollow part of the paper tube and between the six groups of buffer arc plates, when the items are bumped and shaken, the combination of the first spring and the buffer arc plate can produce a buffering effect on the movement of the items, and the second spring and the bottom plate at the bottom can also produce a buffering effect on the items. The corrugated connecting plate installed in the annular groove can strengthen the supporting force of the outer side of the paper tube, so that the paper tube can resist extrusion to a certain extent. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0011] Figure 1 It is a top view of the utility model;

[0012] Figure 2 It is a front sectional view of the utility model.

[0013] In the figure: 1. paper tube, 11. outer wall of paper tube, 12. inner wall of paper tube, 13. annular groove, 14. hollow part of paper tube, 2. corrugated connecting plate, 3. first spring, 4. buffer arc plate, 5. second spring, 6. bottom plate. DETAILED DESCRIPTION

[0014] In order to more clearly illustrate the technical solution of the utility model, the utility model is further described below in conjunction with the accompanying drawings.
