Detailed Description

The following description of the embodiments of the present invention is provided for illustrative purposes, and other advantages and effects of the present invention will become apparent to those skilled in the art from the present disclosure.

Please refer to fig. 1 to 4. It should be understood that the structures, ratios, sizes, and the like shown in the drawings and described in the specification are only used for matching with the disclosure of the specification, so as to be understood and read by those skilled in the art, and are not used to limit the conditions under which the present invention can be implemented, so that the present invention has no technical significance, and any structural modification, ratio relationship change, or size adjustment should still fall within the scope of the present invention without affecting the efficacy and the achievable purpose of the present invention. In addition, the terms "upper", "lower", "left", "right", "middle" and "one" used in the present specification are for clarity of description, and are not intended to limit the scope of the present invention, and the relative relationship between the terms and the terms is not to be construed as a scope of the present invention.

The first embodiment is as follows: referring to fig. 1 to 3, the present invention provides a fire-fighting water curtain hose, which includes a hose 1 having a plurality of water spraying holes 2, wherein the hose 1 includes a woven layer 3 and a lining 4 located inside the woven layer 3.

The foldable bicycle further comprises a support 5, wherein the support 5 is composed of a support arm 6 and elastic arms 7 positioned at two ends of the support arm 6, the support arm 6 and the elastic arms 7 are integrally formed spring pieces, and the elastic arms 7 are folded through elasticity. The surface of weaving layer 3 is equipped with fixed cover 8 and stop collar 9, and support arm 6 is fixed in the inside of fixed cover 8, and elastic arm 7 movable mounting is in the inside of stop collar 9. The limiting sleeve 9 and the tail end of the elastic arm 7 are provided with limiting devices which are matched with each other.

Specifically, when the hose 1 is in the retracted state (i.e. there is no water in the hose 1), referring to fig. 2, the support arm 6 and the elastic arms 7 on both sides are attached to the hose 1, i.e. the two elastic arms 7 are in the folded state; when the water hose 1 is filled with water, referring to fig. 1, the water hose 1 expands, and the elastic arm 7 on the surface of the water hose 1 gradually supports along with the expansion of the water hose 1, so that the bracket 5 and the ground form a fixed pivot, thereby preventing the water hose 1 from rotating, fixing the water spraying direction of a water spraying opening, and forming a stable vertical water curtain.
