However, the existing technology has the following shortcomings:

[0003] After using the existing fire hose, the user usually needs to roll it up by himself and put it in the fire box. When rolling up the used fire hose, due to the accumulated water inside the fire hose, the accumulated water inside needs to be drained out to facilitate the rolling up of the fire hose, which is very laborious. In addition, when rolling up, the user usually rolls up the hose by himself. The irregular rolling up of the hose leads to the unsatisfactory rolling up of the hose, which is inconvenient to use the next time.

[0018] (2) The present invention adds a retracting mechanism to the winding device, and uses an adjusting handle to connect with the ball screw to drive the ball screw to rotate. The guide member on the ball screw can drive the moving seat to move when it rotates, thereby driving the connecting rod and the slider to change the angle.

[0020] (4) The present invention adds a rotating mechanism to the squeezing mechanism, which enables the squeezing mechanism to rotate on the winding disk. When the fire hose needs to be wound up to drain water, the squeezing mechanism is driven by the rotating mechanism to rotate and adjust to a state parallel to the winding device, and the fire hose can be squeezed by the squeezing mechanism to drain water. When the squeezing mechanism is not needed, the squeezing mechanism can be driven by the rotating mechanism to rotate and adjust its position, so that it will not cause obstruction to the winding device, and the flexibility is strong.

[0021] (5) The present invention adds a locking mechanism on one side of the extrusion mechanism, and the upper frame and the lower frame of the extrusion mechanism can be separated by means of the locking mechanism, which not only facilitates the removal of the internal fire hose, but also facilitates the maintenance and replacement of the internal upper extrusion roller and the lower extrusion roller, thereby ensuring the extrusion effect of the extrusion mechanism on the drainage of the fire hose.

DETAILED DESCRIPTION

[0037] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0038] Example 1: Please refer to Figure 1-Figure 7 , the specific embodiments of the present invention are as follows:

[0039] A quick reeling device for an indoor fire hose and a method for using the same, the structure of which comprises a fire box 1, a fire hydrant 2, a reeling device 3 and a fire hose 4. The fire box 1 is provided with the fire hydrant 2 and the reeling device 3 installed inside, and the reeling device 3 is provided with a fire hose 4 for fire extinguishing.

[0040] See also Figure 2-Figure 3 The winding device 3 includes a winding drum 31, a retracting mechanism 32 and a drainage device 33. The winding drum 31 is provided with a retracting mechanism 32 capable of winding and winding the fire hose 4. The side wall of the winding drum 31 is provided with a drainage device 33. The drainage device 33 can discharge the accumulated water remaining in the fire hose 4 when the fire hose 4 is wound.

[0041] See also Figure 4-Figure 5The cam 314 is provided with a plurality of stoppers 316 to move the cam 314 upwards and downwards to move the cam 314 downwards.

[0042] See also Figure 5-Figure 6 The retraction mechanism 32 includes a ball screw 321, a movable seat 322, a connecting rod 323, a slider 324, a placement plate 325, a mounting seat 326 and a baffle 327. One end of the ball screw 321 is connected to the adjustment handle 313, and the ball screw 321 is slidably matched with the movable seat 322 by means of a guide. A plurality of connecting rods 323 are arranged in a circular array on the movable seat 322, and the other ends of the plurality of connecting rods 323 are rotatably matched with the slider 324. One end of the slider 324 is embedded in the limiting groove 315 and slidably matched with the limiting groove 315. A placement plate 325 is installed on the top of the slider 324, and a mounting seat 326 is fixed at one end of the placement plate 325. A baffle 327 that is rotatably matched with the mounting seat 326 through a rotating shaft can limit the fire hose 4 when it is rolled up to prevent the fire hose 4 from falling from one side.

[0043] See also Figure 4-Figure 6 By adjusting the handle 313 and connecting it to the ball screw 321, the ball screw 321 can be driven to rotate. With the help of the guide piece on the ball screw 321, the movable seat 322 can be driven to move when it rotates. As the movable seat 322 moves, the connecting rod 323 and the slider 324 will change their angles. Since the slider 324 slides with the limiting groove 315, the limiting groove 315 limits the sliding of the slider 324, so that the slider 324 can only move up and down in the limiting groove 315. As the slider 324 moves up and down, the diameters of several groups of placement plates 325 can be adjusted, so that the placement plates 325 can be suitable for winding and placing fire hoses 4 of different lengths.

[0044] See also Figure 7Since a mounting seat 326 is fixed to one end of the placement plate 325, and a baffle 327 is rotated on the mounting seat 326 through a rotating shaft, when the fire hose 4 that has been rolled up on the placement plate 325 needs to be removed for use, the baffle 327 located on the mounting seat 326 is rotated to rotate several baffles 327 to a flat state. At this time, the baffle 327 loses its limiting effect on the fire hose 4, and the fire hose 4 can be removed from one side for use.

[0045] See also Figure 6-Figure 7 A side plate 11 is installed on the top of one group of placement plates 325, and a winding rod 12 is fixed on the side plate 11. A gap is left between the winding rod 12 and the placement plate 325. The gap is the thickness of the fire hose 4, so that the fire hose 4 can be folded and placed on the winding rod 12 when winding.

[0046] Example 2: Please refer to Figure 8-Figure 13 , the specific embodiments of the present invention are as follows:

[0047] See also Figure 8 The drainage device 33 includes an extrusion mechanism 331, a rotation mechanism 332 and a locking mechanism 333. One side of the extrusion mechanism 331 is connected to the rotation mechanism 332, the bottom of the rotation mechanism 332 is connected to the winding disk 31, and the locking mechanism 333 is installed on the side of the extrusion mechanism 331 away from the rotation mechanism 332.

[0048] See also Fig. 9 The squeezing mechanism 331 includes an upper frame 41, a lower frame 42, a rotating shaft hinge 43, an upper squeezing roller 44 and a lower squeezing roller 45. The lower frame 42 is provided at the bottom of the upper frame 41. The upper frame 41 and the lower frame 42 are rotatably matched through the rotating shaft hinge 43 on one side, so that the upper frame 41 and the lower frame 42 can rotate. The upper frame 41 is rotatably matched with an upper squeezing roller 44, and the lower frame 42 is installed with a lower squeezing roller 45. The squeezing rings on the upper squeezing roller 44 and the lower squeezing roller 45 are alternately arranged at intervals, so that when the fire hose 4 is squeezed, the squeezing and drainage effect of the water accumulated inside the fire hose 4 can be guaranteed.

[0049] See also Fig.10 The locking mechanism 333 includes a bottom plate 51, a buckle plate 52, a fixed plate 53, a torsion spring 54 and a snap plate 55. The bottom plate 51 is fixed to the upper frame 41. The buckle plate 52 and the fixed plate 53 are rotatably engaged on the bottom plate 51. A torsion spring 54 is installed between the buckle plate 52 and the fixed plate 53. The other end of the buckle plate 52 is movably engaged with the snap plate 55, and the snap plate 55 is connected to the lower frame 42.

[0050] See also Figure 8-Figure 10By rotating the fixing plate 53 until it contacts the bottom plate 51, the rotation of the fixing plate 53 will drive the torsion spring 54 to rotate together, thereby limiting and fixing the buckle plate 52, so that the buckle plate 52 will not fall off when it is movably engaged with the locking plate 55, thereby fixing the upper frame 41 and the lower frame 42.

[0051] See also Figure 11-Figure 12 The rotating mechanism 332 includes a mounting plate 61, an adjusting seat 62, a positioning column 63, an adjusting column 64, a rotating block 65 and a top ball 66. Two adjusting seats 62 are symmetrically mounted on the mounting plate 61. Top balls 66 are mounted inside the two adjusting seats 62. Positioning columns 63 and adjusting columns 64 are respectively mounted on the two adjusting seats 62. The positioning column 63 is fixed to one group of adjusting seats 62 and contacts one of the top balls 66. The adjusting column 64 is threadedly matched with the other group of adjusting seats 62. A rotating block 65 is mounted between the two groups of adjusting seats 62. The top of the rotating block 65 is fixed to the upper frame 41. Arc grooves are provided on both sides of the rotating block 65, and the arc grooves contact the top balls 66 on both sides.

[0052] See also Fig.12 By rotating the adjusting column 64 and with the help of the threaded cooperation between the adjusting column 64 and the adjusting seat 62, the adjusting column 64 can be moved in the adjusting seat 62, thereby adjusting the degree of squeezing of the top ball 66. When it is necessary to fix the rotating block 65, the adjusting column 64 is rotated to squeeze the top ball 66, which cooperates with the top ball 66 fixed on the other side, so that the rotating block 65 can be fixed so that it does not rotate.

[0053] Based on the above embodiment, a method for quickly reeling in an indoor fire hose is specifically implemented as follows:

[0054] S1, when the fire hose 4 needs to be used, the fire box 1 in the room is opened, and the reel 3 is removed from the fire box 1 through the hanging ring 311, and then the baffle 327 on the mounting seat 326 is rotated to rotate the plurality of baffles 327 to a flat state, at which time the baffle 327 loses its limiting effect on the fire hose 4;

[0055] S2, and then by rotating the fixing plate 53 upward, the rotation of the fixing plate 53 will drive the torsion spring 54 to rotate together, so that the fixing of the gusset plate 52 disappears, and the movable engagement between the gusset plate 52 and the engaging plate 55 is disengaged, so that the upper frame 41 and the lower frame 42 can be separated, so that the fixed fire hose 4 can be removed, and the fire hose 4 can be removed from the winding device 3 from one side for use;

[0056] S3, when the fire hose 4 needs to be reeled in after use, the drainage device 33 is rotated to a parallel state with the retracting mechanism 32 through the rotating mechanism 332, and then the adjusting column 64 is rotated. With the help of the threaded cooperation between the adjusting column 64 and the adjusting seat 62, the adjusting column 64 squeezes and fixes the top bead 66, and cooperates with the top bead 66 fixed on the other side, so as to fix the rotating block 65 and prevent it from rotating;

[0057] S4, then fold the fire hose 4 from the middle part, pass it through the middle of the squeezing mechanism 331, and insert the folded part from one side into the winding rod 12 of the winding device 3, and use the winding rod 12 to limit the fire hose 4.

[0058] S5, then move the baffles 327 located on the plurality of mounting seats 326 to reset the baffles 327. At this time, the baffles 327 can limit the fire hose 4 to prevent the fire hose 4 from deflecting when being rolled up;

[0059] S6, then hold the rotating ring 312 on one side of the winding drum 31 with one hand, and rotate the rotating plate 314 on the winding drum 31 with the other hand, and drive the winding drum 31 and the retracting mechanism 32 thereon to rotate together by rotating the rotating plate 314, so that the fire hose 4 can be reeled up;

[0060] S7, as the fire hose 4 is rolled up, it will contact the upper squeezing roller 44 and the lower squeezing roller 45 on the squeezing mechanism 331, squeezing the fire hose 4, and squeezing the remaining accumulated water inside the fire hose 4, so as to facilitate the subsequent rolling;

[0061] S8, after completing the winding of the fire hose 4, since connectors are installed at both ends of the fire hose 4, the winding is completed when the connectors are in contact with the squeezing mechanism 331. At this time, the squeezing mechanism 331 can play a role of fixing and limiting the two connectors of the fire hose 4, so that the connectors will not collide when the winding device 3 is placed in the fire box 1, and the winding device 3 is placed in the indoor fire box 1 to complete the rapid winding of the fire hose 4.

[0062] In the description of the present invention, it is necessary to understand that the indicated orientation or positional relationship is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0063] The above are only specific implementation methods of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be covered by the protection scope of the present application.
