[0038] The water hose adjusting mechanism 3 comprises a movable plate 31, one end of the movable plate 31 is fixedly provided with a limiting block 32 facing the fixing plate 1, the limiting block 32 is located in the second movable groove 14 and is in sliding fit with the inner wall of the second movable groove 14, a second spring 33 is fixedly arranged on the limiting block 32, one end of the second spring 33 away from the limiting block 32 is fixedly connected with the inner wall of the second movable groove 14, and an installation groove 34 is formed in the movable plate 31, the limiting block 32 facilitates the installation of the movable plate 31 in the second movable groove 14, the movable plate 31 can only slide along the inner wall of the second movable groove 14, and the second spring 33 facilitates the movement of the limiting block 32 and the movable plate 31 towards the pressing plate 251.

[0039] A rotating rod 35 is rotatably arranged in the installation groove 34, one end of the rotating rod 35 is inserted into the limiting block 32 and is fixedly sleeved with a gear 36, an opening is formed in the limiting block 32 corresponding to the gear 36, a toothed plate 15 is vertically fixedly arranged in the second movable groove 14, the toothed plate 15 is inserted into the opening and is engaged with the gear 36, a cam disc 37 is fixedly sleeved with the middle part of the rotating rod 35, and a plurality of recesses are formed in the outer wall of the cam disc 37.

[0040] Two symmetrical spiral grooves are formed in the rotating rod 35, the spiral grooves are composed of two thread grooves with the same pitch and opposite rotation directions, which is equivalent to reciprocating screw control of the movement of the movable ring 38, two movable rings 38 are threadedly sleeved with the rotating rod 35, the movable rings 38 are in thread fit with the spiral grooves, two limiting plates 39 are symmetrically arranged on the outer wall of the movable ring 38, two groups of horizontal grooves 310 are formed in the top surface of the movable plate 31, the horizontal grooves 310 are in communication with the inner wall of the installation groove 34, a back-shaped plate 311 is movably arranged in each of the two groups of horizontal grooves 310, the lower end of the back-shaped plate 311 passes through the horizontal groove 310 and is fixedly provided with an adjusting plate 312, one end of the limiting plate 39 away from the movable plate 31 is inserted into the back-shaped plate 311 and is in sliding fit with the inner wall of the back-shaped plate 311, a third spring 313 is fixedly arranged on the inner top wall of the back-shaped plate 311, and the lower end of the third spring 313 is fixedly connected with the limiting plate 39.

[0041] The rotating rod 35 is installed through the installation groove 34, as the fire hose is continuously rolled up, the diameter of the fire hose is continuously increased, the movable plate 31 drives the limiting block 32 to slide along the inner wall of the second movable groove 14, and the rotating rod 35 and the gear 36 are simultaneously moved, at this time, the gear 36 drives the rotating rod 35 to rotate through the toothed plate 15.

[0042] When the rotating rod 35 rotates, the two movable rings 38 are controlled to move in opposite directions. When the movable rings 38 move, the limiting plates 39, the back-shaped plates 311 and the adjusting plates 312 move synchronously. When the movable rings 38 move, the limiting plates 39, the back-shaped plates 311 and the adjusting plates 312 move synchronously. The two adjusting plates 312 constantly move back and forth to adjust the rolled fire hose, so as to increase the neatness of the rolled fire hose. The third spring 313 pushes the back-shaped plate 311 to move and makes the adjusting plate 312 always contact the surface of the pressing plate 251, so as to reduce the possibility that the adjusting plate 312 is difficult to adjust the initially rolled fire hose due to the increasing diameter of the continuously rolled fire hose.

[0043] The first magnetic block 314 is fixedly arranged on the top surface of the movable plate 31 towards one end of the fixed plate 1. The control ring 16 is rotatably inserted into the front side of the fixed plate 1. The second magnetic block 17 is fixedly arranged on the inner side of the control ring 16. When the movable plate 31 moves towards the control ring 16, the first magnetic block 314 and the second magnetic block 17 are attracted. When the movable plate 31 continuously moves, the first magnetic block 314 and the second magnetic block 17 are attracted, which facilitates the fixation of the movable plate 31 in the control ring 16. Thus, the position of the movable plate 31 is fixed. Then, the operator rotates the control driving rod 24 to control the rotation of the two internal threaded rings 242. When the two internal threaded rings 242 expand, the two inclined plates 252 are unfolded. Then, the pressing plate 251 is reset by the inclined plate 252, thereby reducing the distance between the pressing plate 251 and the cylinder 22. When the pressing plate 251 is reset, the rolled fire hose is no longer limited. Then, the operator can easily take the fire hose.

[0044] The blowing mechanism 4 is arranged in the fire hose adjusting mechanism 3. The blowing mechanism 4 includes the hollow plate 41 and the piston plate 42. The hollow plate 41 is fixedly arranged on the side wall of the movable plate 31. The piston plate 42 is movably arranged in the hollow plate 41 and connected to the inner wall of the hollow plate 41 by the fourth spring 43. The bottom surface of the hollow plate 41 is fixedly inserted with a plurality of nozzles 44. The side wall of the piston plate 42 is fixedly arranged with the abutting rod 45. The abutting rod 45 is inserted into the installation slot 34 away from the piston plate 42 and slidably abuts the outer wall of the cam disc 37. When the rotating rod 35 rotates, the cam disc 37 rotates synchronously. The fourth spring 43 pushes the piston plate 42 and the abutting rod 45 to move, and the abutting rod 45 always abuts the outer wall of the cam disc 37. When the cam disc 37 rotates, the abutting rod 45 and the piston plate 42 are continuously pushed to move, so that the piston plate 42 moves back and forth in the hollow plate 41, and the airflow is continuously pushed into the nozzles 44, so that the nozzles 44 continuously spray airflow to blow the surface of the fire hose.

[0045] The rolling mechanism 2 is used to roll the fire hose. The fire hose adjusting mechanism 3 is used to adjust the position of the fire hose. The blowing mechanism 4 is used to clean the sundries on the surface of the fire hose.

[0046] Working principle: When using the fire hose reeling device, firstly, one end of the fire hose is wound around the adjustable bottom plate 25, and then the motor 21 drives the cylinder 22 and the adjustable bottom plate 25 to rotate, thereby reeling the fire hose;

[0047] As the fire hose is continuously wound, its diameter increases, prompting the movable plate 31 to drive the limit block 32 to slide along the inner wall of the second movable groove 14, and at the same time driving the rotating rod 35 and the gear 36 to move synchronously. At this time, the gear 36 drives the rotating rod 35 to rotate through the toothed plate 15. When the rotating rod 35 rotates, it is easy to control the two movable rings 38 to move in opposite directions. As the movable ring 38 moves, it drives the limit plate 39, the circular plate 311 and the adjustment plate 312 to move synchronously, so that the wound fire hose is adjusted by the continuous reciprocating motion of the two adjustment plates 312.

[0048] When the driving rod 24 rotates, the two internal thread rings 242 are controlled to rotate in opposite directions through the two sections of external threads with opposite thread directions. When the two internal thread rings 242 expand, the two inclined plates 252 are caused to unfold, and then the pressing plate 251 is pulled back to its original position by the inclined plate 252, thereby reducing the distance between the pressing plate 251 and the cylinder 22. As the pressing plate 251 is reset, the wound fire hose loses its limit, making it easier for the operator to take the fire hose.

[0049] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
