[0023] Next, the technical solutions in the embodiments of the present application will be clearly described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

[0024] Embodiment 1:

[0025] This embodiment provides an expandable water belt, including:

[0026] Inner belt body 1;

[0027] Outer belt body 2;

[0028] Among them, the outer belt body 2 is arranged outside the inner belt body 1, and an expansion cavity 3 is formed between the outer belt body 2 and the inner belt body 1.

[0029] It can be seen from this embodiment that an expandable water belt includes an outer belt body 2 and an inner belt body 1;

[0030] An expansion cavity 3 is formed between the outer belt body 2 and the inner belt body 1. During use, when the outer belt body 2 is stressed, the force is absorbed and buffered through the expansion cavity 3, thereby reducing the damage of the external force to the inner belt body 1, thus achieving a buffering effect and enabling the inner belt body 1 to be used stably;

[0031] By providing the outer belt body 2 and the inner belt body 1, and forming the expansion cavity 3 to absorb the force, the service life of the water belt is extended.

[0032] Embodiment 2:

[0033] This embodiment provides an expandable water belt, which, in addition to including the technical solutions of the above embodiment, further has the following technical features.

[0034] Through groove 4, the through groove 4 is arranged on the wall surface of the inner belt body 1.

[0035] It can be seen from the present embodiment that by providing a through groove 4 on the wall surface of the inner belt body 1, during use, the fluid will flow into the expansion chamber 3 along the through groove 4, thereby becoming a medium for filling the expansion chamber 3, and when the water hose is subjected to force, it will return to the inner belt body 1 through the through groove 4, thereby absorbing the force through the movement state of the fluid between the expansion chamber 3 and the inner belt body 1, and effectively relieve the pressure in the expansion chamber 3 without affecting the shock-absorbing effect, thereby preventing the water hose from being subjected to excessive force and causing the expansion chamber 3 to burst.

[0036] Embodiment 3:

[0037] This embodiment provides an expandable water hose, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0038] The support ring 5 is provided in plurality in the expansion chamber 3.

[0039] It can be seen from this embodiment that the expansion chamber 3 is supported by providing a support ring 5 in the expansion chamber 3 to prevent the inner belt body 1 and the outer belt body 2 from sticking to each other, thereby preventing the fluid from entering the expansion chamber 3 for effective filling.

[0040] Embodiment 4:

[0041] This embodiment provides an expandable water hose, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0042] The support ring 5 is made of water-absorbing material.

[0043] It can be seen from this embodiment that the support ring 5 expands after absorbing water and can effectively open the inner belt body 1 and the outer belt body 2, so that the fluid can enter the expansion cavity 3 better.

[0044] Embodiment 5:

[0045] This embodiment provides an expandable water hose, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0046] The wear-resistant protrusion 6 is arranged on the outside of the outer belt body 2 .

[0047] It can be seen from the present embodiment that wear-resistant bumps are integrally formed on the outer wall surface of the outer belt body 2 , and the wear-resistant bumps can protect the outer belt body 2 and extend the service life of the outer belt body 2 .

[0048] Embodiment 6:

[0049] This embodiment provides an expandable water hose, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0050] Both ends of the inner belt body 1 and the outer belt body 2 are fixed by hot pressing and melting.

[0051] As can be seen from this embodiment, after the outer belt body 2 is sleeved outside the inner belt body 1, a water belt is formed, and the two sides of the water belt are fixed by hot pressing and melting, so that the sealing performance of the expansion cavity 3 can be effectively improved.

[0052] Embodiment 7:

[0053] This embodiment provides an expanding water belt. In addition to including the technical solutions of the above embodiments, it also has the following technical features.

[0054] A metal hoop 7 is arranged outside the hot pressing and fusing surface of the inner belt body 1 and the outer belt body 2.

[0055] As can be seen from this embodiment, by arranging the metal hoop 7 to protect the hot pressing and fusing surface of the inner belt body 1 and the outer belt body 2, a protective effect is achieved.

[0056] The embodiments of the present application have been described above in conjunction with the accompanying drawings. Without conflict, the embodiments and the features in the embodiments in the present application can be combined with each other. The present application is not limited to the above specific embodiments. The above specific embodiments are merely illustrative and not restrictive. Under the inspiration of the present application, those of ordinary skill in the art can also make many forms without departing from the purpose of the present application and the scope protected by the claims, and all of them belong to the protection scope of the present application.
