Description

Technical Field

[0001] The utility model belongs to the technical field of fire fighting equipment, in particular to a sleeve-type retractable fire fighting water hose. Background Art

[0002] The fire hose is a hose used to deliver water to the fire scene. Its main functions include spraying water and absorbing water. When the fire truck cannot reach the fire scene directly, it is necessary to connect the fire hose to the fire truck, connect the other end of the hose to the water gun, start the fire truck's water pump, and spray water to extinguish the fire. When the water in the fire truck is used up, it can also be refilled with water through the hose.

[0003] Traditional fire hoses are prone to forming knots during use due to improper winding or hanging in a fixed place, or incorrect folding of the hose. When water passes through the knot, it will generate strong torque, which may cause the hose gun to slip out of the hand. Under high pressure, it is very dangerous for the hose gun to slip out of the hand, which will not only injure the user, but also affect the firefighting work due to the loss of control of the hose gun, thus seriously affecting the firefighting effect.

[0024] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present utility model, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0025] Please refer to Figure 1-4 The utility model provides a sleeve-type retractable fire hose, including a hose 1, the outer tube wall of the hose 1 is sleeved with a folding mechanism, the folding mechanism includes a plurality of folding frames 2, the adjacent folding frames 2 are hinged by a connecting mechanism, the folding frames 2 are circular in shape, at least two connecting members 7 are arranged on the inner side of the folding frames 2, the hose 1 is connected to the folding frames 2 by the connecting members 7,

[0026] In this embodiment, the material of the folding frame 2 is titanium alloy. Titanium alloy is a lightweight and high-strength metal material with a very high melting point, and can maintain stability in a high temperature environment. The connecting mechanism is a hinge 3, and other common connecting mechanisms on the market such as bearings can also be used, but are not limited to this. Joints 8 are provided at both ends of the water hose 1. In this embodiment, the folding frames 2 at both ends of the water hose 1 are fixedly connected to the joints 8. The structure of the joints 8 is well known to those skilled in the art and will not be repeated here. The pipe wall of the water hose 1 is provided with a plurality of folds 4. The connecting mechanism includes a limiting device, and the limiting device includes a limiting column 5 and a limiting plate 6. The embodiment of the utility model can limit the maximum opening angle of the folding frame 2 during use through the limiting device to ensure that the folding frame 2 will not squeeze the water hose 1, resulting in a poor firefighting effect.

[0027] The main reasons why fire hoses become knotted during use are as follows:

[0028] First, improper use is the main reason for the knotting of the hose 1. Some personnel may not be familiar with the correct use of the fire hose, resulting in improper operation when laying or storing the hose 1, which in turn causes the hose 1 to become knotted. In addition, randomly folding or stacking the hose 1 may also cause the hose 1 to be tangled unevenly, forming a knot.

[0029] Secondly, improper storage is also an important factor leading to the knotting of the hose 1. If the hose 1 is not properly rolled up or hung in a fixed place during storage, but is randomly piled up in a corner or on the ground, it is easy to get knotted due to external force squeezing or movement.

[0030] If the fire hose becomes tangled during use, it will cause a series of hazards.

[0031] First of all, knots will directly affect the water flow of the fire hose. When the water supply pressure is too high, water will generate strong torque when passing through the knot, which may cause the water gun to slip out of your hand. Under high pressure, it is very dangerous for the water gun to slip out of your hand. Not only will it injure firefighters, but it may also affect the progress of firefighting work due to the loss of control of the water gun, thus seriously affecting the firefighting effect.

[0032] Secondly, knotting may also cause the water hose 1 to leak during use, especially when the pressure is too high, the interface of the water hose 1 may fall off due to the knotting, which not only reduces the fire extinguishing efficiency, but also may delay the fire extinguishing time due to leakage.

[0033] In addition, knots may also affect the operation of firefighters. In the emergency firefighting process, any factors that affect the smoothness of operation may bring serious consequences. Knotted fire hoses may make it impossible for firefighters to quickly and accurately operate the hoses in an emergency, thus affecting the smooth progress of firefighting work.

[0034] The utility model arranges a folding mechanism on the outer side of the water hose 1 so that the water hose 1 can be conveniently and quickly folded and stored together through the folding frame 2 when the water hose 1 is stored, and the folding process is assisted by the folding line 4. When in use, it is only necessary to connect the water inlet end connector 8 to the fire hydrant or the fire truck, and then directly take the water outlet end connector 8 to the location where the fire extinguishing operation is required. At this time, the fire hose will automatically extend with the unfolding of the folding frame 2, thereby avoiding accidents caused by the knotting of the water hose 1 during the fire extinguishing process, thereby ensuring the normal progress of the fire extinguishing operation and the personal safety of the user.

[0035] The embodiment of the utility model provides a plurality of folds 4 on the outer tube wall of the water hose 1 so that the water hose 1 can be stored more conveniently and quickly.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
