[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-5 , an embodiment provided by the utility model:

[0025] A fire hose reel for fire fighting, comprising:

[0026] The main body comprises a base 1, a winding reel 11 is rotatably connected to the surface of the base 1, and a fire hose is wound and connected to the surface of the winding reel 11;

[0027] The limiting mechanism includes a fixed plate 2, which is fixedly connected to the top of the winding drum 11. A guide tube 21 is fixedly connected to the surface of the fixed plate 2, a spring 22 is fixedly connected to the surface of the guide tube 21, a movable rod 23 is fixedly connected to the surface of the spring 22, the movable rod 23 slides on the surface of the guide tube 21, and a limiting rope 24 is fixedly connected to the surface of the movable rod 23. The limiting mechanism is at the top of the winding drum 11, and the wrinkled part of the fire hose is wiped off by two groups of limiting ropes 24, so that the fire hose is smoothly wound on the winding drum 11, which makes full use of the winding space of the winding drum 11 and avoids the squeezing damage of the wrinkled part of the fire hose.

[0028] Furthermore, a recovery mechanism is provided on the surface of the base 1 and the winding drum 11, and the recovery mechanism includes a universal wheel 3, which is provided on the lower surface of the base 1, a handle 31 is fixedly connected to the surface of the base 1, a rotating rod 32 is fixedly connected to the surface of the winding drum 11, a limiting ring 33 is fixedly connected to the surface of the rotating rod 32, and a movable tube 34 is rotatably connected to the surface of the limiting ring 33. The four universal wheels 3 at the bottom of the recovery mechanism can facilitate the movement of the equipment. At the same time, in the process of rotating the rotating rod 32, it rotates through the movable tube 34, thereby avoiding the friction when the rotating rod 32 is directly rotated, which is more practical and efficient.

[0029] Furthermore, the fixing plates 2 are in two groups, circular holes are opened on the surface of the fixing plates 2, the guide tubes 21 are in four groups and fixedly connected to the circular holes of the fixing plates 2, and the distance between the two groups of guide tubes 21 on the same group of fixing plates 2 is small, and the fixing plates 2 and the guide tubes 21 are symmetrically distributed on the fixing plates 2.

[0030] Furthermore, the movable rod 23 can slide on the guide tube 21 to the circular hole that passes through the fixed plate 2. The limiting ropes 24 are in two groups. Both ends of the limiting ropes 24 are fixedly connected to the movable rod 23. The limiting ropes 24 are limited between the two groups of fixed plates 2 through the movable rod 23. The two groups of limiting ropes 24 are parallel to each other, and the two groups of limiting ropes 24 have the same spacing as the guide tube 21. The spacing between the limiting ropes 24 is smaller. When the limiting ropes 24 are in a parallel state, they can only pass through the two groups of limiting ropes 24 through a neat fire hose. After passing through the two groups of limiting ropes 24, the fire hose is wrapped around.

[0031] Furthermore, the limiting rope 24 has a deformation property, and the elastic force of the spring 22 acts on the movable rod 23. The movable rod 23 straightens the two groups of limiting ropes 24 through the elastic force of the spring 22. The limiting ropes 24 limit the winding of the fire hose. When the fire hose between the two groups of limiting ropes 24 is in use, the water flow inside the fire hose squeezes the two groups of limiting ropes 24 into an arc shape, and at the same time, the movable rod 23 moves on the guide tube 21 toward the fixed plate 2, squeezing the spring 22. When the water flow of the fire hose stops, under the influence of the elastic force of the spring 22, the limiting ropes 24 become parallel to each other again, limiting the winding shape of the fire hose.

[0032] Furthermore, the reel 11 rotates on the surface of the base 1 through the bearing, and the rotating rod 32 drives the reel 11 to rotate on the base 1 during the rotation. The reel 11 reels the fire hose during the rotation. A handle 31 is provided opposite to the rotating rod 32, so that the handle 31 and the universal wheel 3 can push the entire equipment at the same time, which is convenient for firefighters to quickly move the equipment.

[0033] Furthermore, two groups of limit rings 33 are provided, and the limit rings 33 limit the position of the movable tube 34 on the rotating rod 32. When the firefighter holds the movable tube 34 and rotates it, the rotating rod 32 will rotate in the inner circle of the movable tube 34, so that the friction between the movable tube 34 and the hand is small, thereby protecting the firefighter's hand. The rotating rod 32 can be rotated more quickly through the movable tube 34, thereby increasing its winding speed.

[0034] Working principle: place the fire hose between the two sets of limit ropes 24, pull the fire hose out from the reel 11 for use, when the valve is opened, water flows out from the fire hose, making the fire hose cylindrical, so that the fire hose squeezes the limit rope 24, making the limit rope 24 arc-shaped, and pulling the movable rod 23 to slide on the guide tube 21, squeezing the spring 22, at this time, the limit rope 24 enters the guide tube 21 from the circular hole of the fixed plate 2, when the valve is closed, the water source inside the fire hose disappears, the fire hose becomes flat, and wrinkles appear in some places, causing winding obstacles, and at this time, under the elastic force of the spring 22, the movable rod 23 slides on the guide tube 21 toward the end away from the fixed plate 2, making the two sets of limit ropes 24 straight and parallel to each other, at this time, under the limitation of the two sets of limit ropes 24, the wrinkles of the fire hose are eliminated by the limitation of the limit rope 24, and finally the fire hose is wound on the reel 11.

[0035] In the process of winding up the fire hose through the winding reel 11, it is necessary to manually rotate the rotating rod 32. When the rotation speed is too fast, greater friction will be generated, causing injuries to the firefighter's hands. By installing a movable tube 34 and a limit ring 33 on the surface of the rotating rod 32, the firefighter can hold the movable tube 34 to rotate the rotating rod 32. The friction between the movable tube 34 and the hand is small, which protects the firefighter's hand. The rotating rod 32 can be rotated faster through the movable tube 34 to increase its winding speed. The handle 31 and the universal wheel 3 facilitate pushing the entire equipment, which is convenient for firefighters to quickly move the equipment.

Therefore, the embodiments should be regarded as exemplary and non-limiting from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
