[0022] like Figures 1-3 As shown, this embodiment provides a fire hose reeling device, including a flatbed trolley 1. A reeling device 3 is provided on the flatbed trolley surface 2. The reeling device includes an "in"-shaped folding frame. A reeling shaft 4 is provided on the top of the folding frame. The bottom rear side of the folding frame is hinged to the flatbed surface, and a positioning component is provided between the bottom front side and the flatbed surface.

[0023] In this embodiment of the utility model, the folding frame is composed of a U-shaped rear long frame 5 and a front short frame 6. The top of the front short frame is hinged to the upper middle part of the rear long frame. A rear connecting rod 7 is hinged to the rear long frame below the hinge point between it and the front short frame. A front connecting rod 8 is hinged to the front short frame below the hinge point between it and the rear long frame. The front connecting rod and the rear connecting rod are hinged to each other.

[0024] In this embodiment of the utility model, the bottom of the rear long frame is hinged to the plate surface.

[0025] In this embodiment of the utility model, the positioning component includes a positioning groove 9 opened on the plate surface, which is embedded in the bottom of the former short frame, and a positioning plate 10 that can slide back and forth is provided on the groove of the positioning groove.

[0026] In this embodiment of the utility model, a front slot 11 is provided on the front side of the groove of the positioning groove for the front edge of the positioning plate to be inserted, and a rear sliding groove 12 is provided on the rear side of the groove of the positioning groove for the rear side of the positioning plate to be inserted, and a plurality of springs 13 extending back and forth are connected between the rear end of the positioning plate and the inner rear groove wall of the rear sliding groove.

[0027] In this embodiment of the utility model, a push-pull protrusion 14 is fixedly provided on the top surface of the positioning plate.

[0028] In this embodiment of the utility model, the front short frame is made of a bent round tube.

[0029] In this embodiment of the utility model, the top of the rear long frame is fixed with a "C"-shaped notch 15 with the opening facing backward. The left and right ends of the take-up shaft are located inside the notch. The left and right sides of the notch on the left side of the rear long frame are provided with circular limiting flanges 16 that are coaxially fixed on the take-up shaft for axial limiting of the take-up shaft. The opening of the notch is provided with a removable limiting pin 17 for rearward limiting of the take-up shaft.

[0030] In this embodiment of the utility model, the top of each limiting pin is tied with a connecting rope 18, and the other end of each connecting rope is tied to the side of the rear long frame to prevent the limiting pin from being lost after being pulled out.

[0031] In this embodiment of the utility model, one end of the winding shaft is connected to a hand crank 19, and the other end is coaxially fixed with a nut head 20.

[0032] In this embodiment of the utility model, the bottom of the flatbed trolley is provided with universal wheels equipped with brakes.

[0033] In this embodiment of the utility model, the working principle of the fire hose reel device is as follows:

[0034] In use, a flatbed trolley is used to push the retractor to the position where the fire hose needs to be retracted. One end of the fire hose is first wound onto the retractor shaft. Then, the firefighter uses one hand to rotate the retractor shaft via the hand crank to retract the fire hose. Alternatively, a multi-functional hand drill can be used as a power source. The actuator head of the multi-functional hand drill can be replaced with an actuator head for rotating a nut. The multi-functional hand drill can then be used to rotate the nut head fixed on the retractor shaft, thereby driving the retractor shaft to rotate and retract the fire hose.

[0035] During the winding process, because the fire hose has been pre-organized and stretched straight, it is not easy for the hose to become crooked during winding, and slight crookedness will not affect the winding of the hose because the fire hose is relatively wide. In a few cases where the crookedness is more significant, the firefighters will straighten it first before continuing to wind it up.

[0036] After the fire hose is wound up, the winder and fire hose roll can be pushed together to the fire truck parking location or warehouse using a flatbed trolley. Then, remove the limit pin, take the winder shaft out from the notch, and take out the fire hose roll. Finally, put the winder shaft back into the notch and insert the limit pin back in.

[0037] After use, the fire hose reeling device can be slid open by opening the positioning groove on the positioning plate, releasing the upper limit of the bottom of the front short frame. After the bottom of the front short frame is lifted out of the positioning groove, the rear long frame begins to fold together with the front short frame. Then, at the hinge point between the bottom of the rear long frame and the plate surface, the folded rear long frame and front short frame are rotated backward until they contact the plate surface, thus completing the folding. Finally, the push handle 21 of the flatbed trolley is also folded forward (this is prior art), allowing the fire hose reeling device to be folded and stored in a fire truck or warehouse.

[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
