Description

Technical Field

[0001] The utility model relates to the technical field of fire fighting, in particular to a folding cart capable of rolling up a fire hose. Background Art

[0002] The fire hose needs to be rolled up after each use, and the rolled up fire hose needs to be transported to a designated storage location for use next time. After searching, the patent with announcement number CN218907256U discloses a folding cart that can roll up the fire hose. Although the device can both conveniently roll up the fire hose and conveniently carry the fire hose, when the fire hose is rolled up, there will be residual fire water or foam agent inside. The device cannot drain the residual fire water or foam agent inside when rolling it up, which greatly increases the weight of the rolled up water hose. At the same time, the residual fire water or foam agent inside the fire hose for a long time is easy to cause the rubber material to age, harden, and crack, thereby affecting its service life and use effect. In addition, it is also easy to breed bacteria and algae. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a folding cart that can roll up a fire hose, which solves the problem proposed in the background technology that when the fire hose is rolled up, there will be residual fire water or foam agent inside the fire hose, and the residual fire water or foam agent inside the fire hose cannot be drained out during rolling up, which leads to a significant increase in the weight of the rolled-up hose. At the same time, the residual fire water or foam agent inside the fire hose for a long time can easily cause the rubber material to age, harden, and crack, thereby affecting its service life and use effect. In addition, it is also easy to breed bacteria and algae.

[0004] To achieve the above objectives, the utility model is implemented through the following technical solutions: a foldable cart that can reel in a fire hose, comprising a device body, a handle, a limit block and a baffle, wherein two universal wheels are installed at the bottom of one end of the device body, the top of one end of the device body is rotatably connected to the bottom of the baffle, and the top of the other end of the device body is rotatably connected to the bottom of the vertical plate. A telescopic rod is arranged inside one end of the device body, a supporting foot is welded at the bottom of one end of the telescopic rod, the inside of the vertical plate is rotatably connected to the outside of one end of the hand crank, and a winding rod is welded at one end of the hand crank, a limit block is arranged on one side of the winding rod, two limit blocks are arranged, and the two limit blocks are welded to the vertical plate, the top of the limit block is threadedly connected to the threaded rod, the top of the threaded rod is welded with an adjusting rod, the bottom of the threaded rod is rotatably connected to the top of the lifting frame, and one side of the bottom of the lifting frame is rotatably connected to one end of the first roller, a second roller is arranged below the first roller, and one end of the second roller is rotatably connected to one side of the bottom of the limit block.

[0005] Preferably, one side of the bottom of the device body is rotatably connected to one end of the bottom of the support rod, a circular hole groove is opened at one end of the top of the support rod, and a pin is provided inside the circular hole groove, and the pin is threadedly connected to the hole grooves on both sides of the vertical plate, and connecting blocks are welded on the bottom of both sides of the device body, and a threaded hole is provided on one side of the connecting block. When in use, the pin connected to the connecting block is removed by rotation, and the vertical plate is flipped over and the support rod is rotated so that one end of the support rod can be connected to the hole groove on the side of the vertical plate through the pin, thereby fixing the vertical plate.

[0006] Preferably, a groove is provided on the surface of one side of the limit block, and the groove on one side of the limit block is slidably connected to one end of the lifting frame, and the other end of the lifting frame is L-shaped, which is conducive to limiting the water hose from sliding between the first roller and the second roller through the L-shape at one end.

[0007] Preferably, two holes are provided at one end of the device body, and telescopic rods are inserted into the two holes, spring sheets are welded inside both ends of the telescopic rod, and a spring pin is welded at one end of the spring sheet, and the spring pin is engaged with the holes on both sides of one end of the device body. When the telescopic rod slides outward, the spring pin at one end of the telescopic rod located inside the device body will engage with both sides of the device body, thereby fixing the length of the extended telescopic rod.

[0008] Preferably, both ends of the handle are respectively welded to one end of the two telescopic rods, and a rubber sleeve is provided on the outside of the handle. The baffle is flipped up and then the rolled water hose is placed on one end of the device body close to the baffle, which is conducive to carrying multiple water hoses, and then the handle is lifted to facilitate dragging the cart.

[0009] The utility model provides a foldable cart capable of rolling up a fire hose, which has the following beneficial effects:

[0010] (1) A folding cart that can roll up a fire hose. When the device is in use, the middle of the hose is passed through the gap inside the winding rod, and then the two ends of the hose are placed between the first roller and the second roller respectively. The adjusting rod is rotated so that the adjusting rod can drive the threaded rod to move downward. The threaded rod moves downward and drives the first roller to move downward, so that the first roller and the second roller squeeze the hose between them. Then, the hand crank is rotated so that the hand crank can drive the winding rod to rotate. When the winding rod rolls up the hose, the first roller and the second roller squeeze the remaining water in the hose and discharge it. This avoids a lot of water remaining in the hose after the hose is rolled up.

[0011] (2) The foldable cart capable of retracting a fire hose can press a spring pin at one end of the telescopic rod near the handle and pull the handle outward, so that the handle can drive the telescopic rod to move. When the telescopic rod moves outward, the support surface at the bottom of the device can be extended, thereby facilitating the stability of the device when it is placed.

[0012] This solves the problem that when the fire hose is rolled up, there will be residual fire water or foam inside, and the residual fire water or foam inside cannot be drained out during the rolling process, which greatly increases the weight of the rolled hose. At the same time, the residual fire water or foam inside the fire hose for a long time is easy to cause the rubber material to age, harden and crack, thereby affecting its service life and use effect. In addition, it is easy to breed bacteria and algae. BRIEF DESCRIPTION OF THE DRAWINGS
