The implementation principle of the fire hydrant cabinet structure convenient to roll is as follows:

during the use, open the chamber door earlier, go up the nip roll 411 and be located first accomodating groove 16, lower nip roll 412 is located the second and accomodates groove 17, takes fire extinguisher 13 or hosepipe in the box 1 as required and uses, and the one end that the squirt 15 was installed to the hosepipe passes guiding device 3, then pulls out, and the winding is around the axle 2 reversal when pulling out, and the hosepipe on the winding disc 24 unwinds, also can directly take off winding disc 24 from winding shaft 2 and unwinds.

After use, the fire extinguisher 13 is replaced and the rotating handle 42 is screwed into the threaded hole. Then, the stopper rod 431 is pressed to compress the stopper spring 432, so that the stopper rod 431 is separated from the first rotating base 61, the upper nip roller 411 is rotated out of the first accommodating groove 16, and the upper nip roller 411 is in a horizontal state defined between the first rotating base 61 and the lower end wall of the first accommodating groove 16. When the upper nip roller 411 is in the horizontal state, the first slider 62 moves down by gravity, so that the first driven gear 51 moves down to be engaged with the first engaging gear 18.

Then, the support rod 441 is pressed, the support rod 441 compresses the support spring 442, then the lower flattening roller 412 is rotated out of the second accommodating groove 17 so that the lower flattening roller 412 is in a horizontal state, then the support rod 441 is loosened, the support rod 441 is moved to below the second slider 82 by the support spring 442, the support bolt 444 on the support rod 441 abuts against the bottom surface of the second slider 82, then the support bolt 444 is rotated, the second slider 82 is pushed up by the support bolt 444, and thus the second driven gear 52 is raised and engaged with the second engaging gear 19.

The rotating handle 42 is rotated, the winding shaft 2 drives the first driven gear 51 and the second driven gear 52 to rotate, so that the upper flattening roller 411 and the lower flattening roller 412 rotate, a water belt passing through the space between the upper flattening roller 411 and the lower flattening roller 412 is flattened, the water belt is driven to be wound on the winding disc 24 through the rotation of the winding disc 24, and winding is achieved.

During winding, the water belt passes between the upper flattening roller 411 and the lower flattening roller 412, and the water belt is flattened by the threads on the upper flattening roller 411 and the lower flattening roller 412.

The water in the hosepipe is being followed squirt 15 and is flowing out around rolling up and pacifying the in-process, and the in-process of flowing out, water make not erect by the hosepipe around rolling up, last nip roll 411 and lower nip roll 412 department can be inseparabler with last nip roll 411 and lower nip roll 412 contact, promote the exhibition flat effect.

Along with the winding of the hose, the water gun 15 is clamped at the positions of the two guide rollers 31, the rotation of the rotating handle 42 is stopped, the rotating handle 42 is taken down, and the box door is closed.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: equivalent changes in structure, shape and principle of the present application shall be covered by the protection scope of the present application.
