The utility model will be further described with reference to the accompanying drawings and preferred embodiments.
Example 1
Referring to fig. 1 to 3, the wear-resistant waterproof paper tube according to the present embodiment includes a paper tube main body 1, a waterproof film 2 wound into a tube is attached to an outer wall of the paper tube main body 1, two ends of the waterproof film 2 respectively extend out of two ends of the paper tube main body 1, a portion of the waterproof film 2 extending out of the paper tube main body 1 is composed of a first extending portion 3 attached to an end surface of the paper tube main body 1 and a second extending portion 4 attached to an inner wall of the paper tube main body 1, lock rings 5 respectively disposed at two ends of the paper tube main body 1 are embedded in the paper tube main body 1, and the second extending portion 4 is disposed between the paper tube main body 1 and the lock rings 5.
Further, an annular groove 6 for embedding the second extending portion 4 and the locking ring 5 is formed in the inner wall of the paper tube main body 1, and one side of the annular groove 6 is communicated with the outside.
Further, the width of the locking ring 5 is equal to the width of the annular groove 6; the sum of the thickness of said locking ring 5 and the thickness of the second extension 4 is equal to the depth of the annular groove 6.
Further, one end of the lock ring 5 is provided with a closing-in guide part 7.
In the present embodiment, the waterproof membrane 2 (including the first extension portion 3 and the second extension portion 4) extending out of the paper tube main body 1 is respectively bent and attached to the end face and the inner wall face of the paper tube main body 1, so that the first extension portion 3 covers the end face of the paper tube main body 1, the second extension portion 4 covers the inner wall face of the paper tube main body 1 near the end portion, and finally the locking ring 5 is embedded into the annular groove 6 of the paper tube main body 1, so that the terminal of the waterproof membrane 2 (i.e., the second extension portion 4) is tightly connected with the paper tube main body 1, and the waterproof membrane is prevented from falling off.
