DETAILED DESCRIPTION

[0018] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0019] like Figure 1-4 As shown, the utility model is a fire hose reel for preventing hose deformation, comprising a base plate 1, on which a support plate 11, a bracket 2 and an adjustment box 4 are provided, and on one side of the bracket 2 is a first motor 21, and an output end of the first motor 21 is provided with a rotating rod 23, and the rotating rod 23 is connected to a winding roller 22. When the fire hose needs to be wound up, by turning on the external power switch of the first motor 21, the output end of the first motor 21 drives the rotating rod 23 to rotate, and the rotating rod 23 is rotatably connected to the bracket 2 through a bearing. The rotating rod 23 can drive the entire device arranged in the bracket 2 to rotate, and can drive the winding roller 22 to rotate, so as to start winding up the fire hose.

[0020] The reel 22 is connected to the bidirectional screw rod 3 in a rotatable manner in the cavity, and the bidirectional screw rod 3 is threadedly connected to the connecting frame 32. The connecting frame 32 is connected to the side baffle 33, and the side baffle 33 is slidably connected to the upper surface of the reel 22. When the reeling width of the reel 22 needs to be adjusted according to the fire hose that needs to be reeled in, the bidirectional screw rod 3 in the cavity of the reel 22 is driven to rotate. The rotation of the bidirectional screw rod 3 can drive the connecting frame 32 threaded thereon to start moving inward or outward, and the connecting frame 32 drives the side baffle 33 set when the side is fixed to move left and right, thereby adjusting the required width of the reel 22 when reeling, avoiding the reel 22 being too long during the reeling process, and the fire hose reeling effect being poor, and the width of the reel 22 can be easily adjusted.

[0021] A second motor 41 is provided on the side wall of the regulating box 4, and a screw 42 is provided at the output end of the second motor 41. A slider 43 is threadedly connected to the screw 42, and a sleeve 44 is connected to the upper end of the slider 43. A limit plate 45 is slidably provided in the sleeve 44, and a limit cylinder 47 is provided on the upper end of the limit plate 45. When the fire hose is started to be wound, the fire hose passes through the limit cylinder 47 and is wound on the winding roller 22. By adjusting the rotation of the second motor 41, the second motor 41 can be periodically rotated clockwise or counterclockwise, and then the screw 42 can be driven to rotate. The rotation of the screw 42 can drive the slider 43 threadedly connected to its outer surface to move forward and backward, and the slider 43 drives the limit cylinder 47 to move forward and backward to guide the fire hose. The fire hose can be periodically swung forward and backward so that it is evenly spread on the winding roller 22, so as to avoid the fire hose being piled up at one place on the surface of the winding roller 22 during the winding process, and the fire hose is easily deformed inside, so that it is evenly wound on the winding roller 22 to ensure the winding effect.

[0022] In the above scheme, a telescopic rod 12 is provided on the side of the support plate 11, and a first spring 13 is provided on the outside of the telescopic end of the telescopic rod 12. A mounting block 14 is fixedly provided at the end of the telescopic rod 12. During the winding process, the mounting block 14 is rotatably connected to the squeezing roller 15 through a bearing. The mounting block 14 forms an elastic telescopic structure through the first spring 13 and the telescopic rod 12. The squeezing roller 15 can compress the wound fire hose to avoid the fire hose from being loose, and prevent the fire hose from being too loose and causing wrinkles and deformation after squeezing. As the winding radius of the fire hose increases, the mounting block 14 pushes the telescopic rod 12. When the first spring 13 is compressed to the extreme, the squeezing roller 15 is attached to the fire hose on the surface of the winding roller 22, which can terminate the continuous winding of the fire hose, and avoid the fire hose inside the winding roller 22 being deformed due to excessive pressure caused by the worker continuously winding the fire hose too much.

[0023] In the above scheme, the bidirectional screw rod 3 is rotatably connected to the winding roller 22 via a bearing, and a knob 31 is fixedly provided at the outer end of the bidirectional screw rod 3, and the bidirectional screw rod 3 is conveniently rotated by the knob 31.

[0024] In the above scheme, a slide groove 24 is provided on the surface of the winding roller 22, and a connecting frame 32 is slidably provided in the slide groove 24. The slide groove 24 facilitates the connecting frame 32 to push the side baffle 33.

[0025] In the above scheme, a second spring 46 is provided in the sleeve 44, one end of the second spring 46 is connected to the bottom of the sleeve 44, and the other end is connected to the lower end of the limiting plate 45. The second spring 46 provided in the sleeve 44 can prevent the limiting cylinder 47 from having excessive traction force when guiding the fire hose, thereby causing the fire hose to be pulled and deformed. The provided second spring 46 can effectively ensure the stability of the limiting cylinder 47 during the guiding process.

[0026] Working principle:

[0027] The fire hose reel for preventing hose deformation, when working, drives the bidirectional screw rod 3 to rotate by turning the knob 31, adjusts the width of the side baffle 33 according to the length of the fire hose to be wound, connects the discharge pipe to the surface of the winding roller 22 through the limiting cylinder 47, and then starts to wind up the fire hose by turning on the first motor 21 to rotate the winding roller 22, and then turns on the switch of the second motor 41 to rotate the screw rod 42 at the output end of the second motor 41. The rotation of the screw rod 42 can make the limiting cylinder 47 move back and forth periodically, so that the fire hose is evenly spread on the surface of the winding roller 22, and can avoid the fire hose being concentrated in one place during the winding process, causing the internal fire hose to be deformed, and in the winding process, the squeezing roller 15 can fit on the surface of the fire hose, so as to avoid the fire hose being too loose on the winding roller 22 during the winding process, thereby affecting the winding effect.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
