Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.

During specific implementation, as shown in fig. 1, this embodiment provides a quick coiling mechanism of fire hose, and this quick coiling mechanism of fire hose can carry out quick coiling to the fire hose after using, improves fire control operating efficiency. The winding device specifically comprises a base 100 and a winding component arranged on the base 100; the winding assembly comprises a pair of squeezing rollers 200 which are arranged at intervals and can move relatively, and a squeezing channel for the fire hose to pass through is formed between the two squeezing rollers 200; like this, because can relative movement between squeeze roll 200, the fire hose after the use can pass through the extrusion passageway, under the relative extrusion of squeeze roll 200, can extrude the residual water in the fire hose on the one hand, on the other hand can sticis the fire hose, makes the volume after the fire hose rolling littleer. In order to adjust the distance between the squeezing rollers 200 in a self-adaptive manner, in this embodiment, mounting posts 1100 are disposed on the base 100 corresponding to the two ends of the squeezing rollers 200, wherein the two ends of one of the squeezing rollers 200 are rotatably fitted with the mounting posts 1100, the two ends of the other squeezing roller 200 are rotatably provided with squeezing sliders 300 capable of sliding along the length direction of the mounting posts 1100, and the squeezing sliders 300 are connected with the extension springs 400 disposed in the mounting posts 1100. The extrusion roller 200 can uniformly apply pressure to the fire hose under the action of the elastic force of the extension spring 400, so that the fire hose with different sizes can be adaptively adjusted, and the extrusion efficiency of the fire hose is improved; in addition, in order to prevent damage to the fire hose during the extrusion process, the extrusion roll 200 is sleeved with a flexible anti-slip sleeve. The flexible anti-skidding sleeve can be a rubber sleeve, so that the friction force can be increased on one hand, and the fire hose can be prevented from being damaged by pressure on the other hand. In order to wind the extruded fire hose, the winding assembly further comprises a winding shaft 500 positioned on one side of the extrusion channel, a winding disc 600 which can rotate along with the winding shaft 500 and can be detached is sleeved on the winding shaft 500, and a ratchet mechanism for controlling the winding shaft 500 to rotate in a single direction is fixed at one end of the winding shaft 500. Like this, at the rolling in-process, along with the rotation of rolling axle 500, fire hose evenly twines on rolling dish 600, because ratchet can restrict rolling axle 500 and turn to, consequently can prevent that rolling axle 500 reversal from leading to fire hose to drop under ratchet's effect. The ratchet mechanism provided in this embodiment specifically includes a rotation limiting gear 700 fixed at one end of the winding shaft 500, a pair of abutment posts 800 are rotatably disposed outside the rotation limiting gear 700, one end of each of the two abutment posts 800 close to the rotation limiting gear 700 is provided with an abutment portion capable of abutting against the root of the rotation limiting gear 700, the abutment posts 800 can rotate around one end far away from the rotation limiting gear 700, an adjusting rod 900 capable of abutting against a corresponding one of the abutment posts 800 is further disposed between the two abutment posts 800, and when the adjusting rod 900 abuts against a corresponding one of the abutment posts 800, the abutment portions of the abutment posts 800 are separated from the root of the rotation limiting gear 700. Thus, when the abutting parts of the two abutting columns 800 abut against the rotation limiting gear 700, the limiting function can be achieved to prevent the rolling shaft 500 from rotating; when the abutting part of only one abutting column 800 abuts against the rotation limiting gear 700, the winding shaft 500 can only rotate in one direction, and different abutting columns 800 can control the rotation of the winding shaft 500, so that the waterproof band can be wound or unfolded.

As shown in fig. 1, in order to stably mount the ratchet mechanism and the winding shaft 500, in this embodiment, a mounting portion 110 for rotatably mounting the winding shaft 500 is provided on the base 100, the winding shaft 500 is fixedly connected to the rotation limiting gear 700 after movably passing through the mounting portion 110, and a mounting groove 111 for mounting the rotation limiting gear 700 is provided on an outer side surface of the mounting portion 110. Ratchet can arrange in mounting groove 111, avoids causing the interference to other mechanisms, and in addition, the one end that the limit turned gear 700 was kept away from to the butt post 800 rotates through the pivot and locates the mounting groove 111 outside, the cover has the torsional spring in the pivot, and like this, the butt portion of butt post 800 supports under torsional spring torsion effect and leans on the root of tooth of limit turned gear 700. The corresponding abutting column 800 can be controlled to abut against or separate from the rotation limiting gear 700 by rotating the adjusting rod 900.

As shown in fig. 1, when in use, a fire fighter needs to rotate the winding disc 600 to realize rapid winding of the fire hose, and in this embodiment, a rotating portion is provided at an edge of the winding disc 600, and an anti-slip layer is provided on the rotating portion. The rotation part is arranged to facilitate the rotation of the winding disc 600 by the fire fighter, and in addition, the inner circumferential wall of the winding disc 600 is provided with a limiting clamping groove which is matched with a limiting clamping convex block arranged on the circumferential surface of the winding shaft 500. The spacing clamping groove and the spacing clamping protrusion are matched, so that the winding shaft 500 and the winding disc 600 can rotate simultaneously, and the ratchet mechanism can adjust the steering limitation of the winding disc 600.

In practical application, the present embodiment has a plurality of self-locking universal wheels 1000 at the lower end of the base. The position of the whole device can be conveniently transferred by arranging the universal wheel 1000.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not substantially depart from the scope of the embodiments of the present invention, and are intended to be covered by the claims and the specification.
