Description

Technical Field

[0001] This utility model relates to the field of fire-fighting transportation technology, and in particular to a detachable trolley. Background Technology

[0002] Fire hoses are essential tools in firefighting and rescue operations, used to transport water or other extinguishing agents. They are flexible hoses used to deliver high-pressure water or flame-retardant liquids such as foam. Traditional fire hoses have a rubber inner lining and an outer layer of woven linen. Advanced fire hoses are made of polymer materials such as polyurethane. Both ends of a fire hose have metal connectors, allowing for the attachment of another hose to extend the distance or nozzles to increase the liquid spray pressure. Fire hoses are typically transported using trolleys. However, traditional trolleys are inconvenient for storing and moving hoses, and cannot be used on stairs, making them extremely cumbersome to use. Utility Model Content

[0003] The main purpose of this utility model is to provide a detachable trolley, which aims to solve the problem that trolleys used for transporting fire hoses are inconvenient for storing and moving hoses, and cannot be used for transporting hoses when encountering stairs, making them extremely inconvenient to use.

[0004] In order to achieve the above-mentioned utility model objectives, this utility model proposes a detachable trolley, including a base plate, four sets of moving mechanisms are provided at the bottom of the base plate, two storage mechanisms are provided at the top of the base plate, and a snap-fit ​​mechanism is provided between the two storage mechanisms and the base plate;

[0005] The moving mechanism includes a connector, a rotating frame, three connecting rods, three support pads, three rotating shafts, six mounting discs, several second springs, and six mounting cylinders. The connector is rotatably connected to the bottom of the base plate, the rotating frame is rotatably connected inside the connector, the rotating shafts are rotatably connected inside the rotating frame, the mounting discs are fixedly mounted on the side wall of the rotating shafts, the mounting cylinders are movably connected to one side of the mounting discs via second springs, the connecting rods are fixedly mounted on the side wall of the rotating frame, and the support pads are fixedly mounted on one end of the connecting rods.

[0006] Furthermore, the rotating frame is triangular in shape, and the three rotating shafts are located on one side of the three vertices of the rotating frame.

[0007] Furthermore, the three connecting rods are located between the three rotating shafts, and the support pad is an arc-shaped pad.

[0008] Furthermore, one end of the second spring is fixedly installed on the side wall of the mounting plate, and the other end of the second spring is fixedly installed on the inner wall of the mounting cylinder.

[0009] Furthermore, a mounting base is fixedly installed on the top of the base plate, and a pull rod is rotatably connected inside the mounting base.

[0010] Furthermore, a storage bag is fixedly installed inside the pull rod.

[0011] Furthermore, the storage mechanism includes a storage rack, a threaded rod, a slider, and a folding frame. The threaded rod is rotatably connected inside the storage rack. A groove is provided inside the storage rack. The slider is slidably connected inside the groove and movably connected to the side wall of the threaded rod. A storage slot is provided on the inner wall of the storage rack. One end of the folding frame is rotatably connected inside the storage slot, and the other end of the folding frame is movably connected to the slider.

[0012] Furthermore, the inner wall of the storage rack is provided with a movable groove, and the bottom part of the folding rack is slidably connected inside the movable groove.

[0013] Furthermore, a support frame is fixedly installed on the top of the base plate, and the support frame fits into the storage rack.

[0014] Furthermore, the latching mechanism includes a first spring and a latching block. The top of both the storage rack and the base plate are provided with positioning holes. The inner wall of the positioning hole is provided with a latching groove. A positioning component is fixedly installed at the bottom of the storage rack. The latching block is movably connected inside the positioning component through the first spring, and the latching block fits into the latching groove.

[0015] Beneficial effects:

[0016] This utility model's detachable trolley features a moving mechanism. When the base plate needs to be pulled up the stairs, the mounting cylinders on one side of the two mounting plates inside the rotating frame can contact the stair surface, allowing the base plate to be secured to the stairs via the mounting cylinders. At this time, the support pads between the two mounting cylinders can support the corners of the stairs, preventing the rotating frame from getting stuck on the stairs. Then, pulling the base plate again causes the rotating frame to rotate, and the three mounting cylinders inside the rotating frame contact the stair surface one by one, allowing the base plate to be easily pulled up the stairs. The second spring can be used to support the mounting cylinders on one side of the mounting plates, providing a certain buffering effect when the base plate passes over uneven surfaces, preventing the base plate from shaking too much, and making the transport of water hoses more flexible and convenient.

[0017] This utility model relates to a detachable trolley. By rotating the threaded rod, the slider can move inside the slide groove. The movement of the slider can unfold or fold the folding rack inside the storage slot. When the folding rack is unfolded, the storage rack is a separate unit and can be used to store water hoses alone. When the folding rack inside one of the storage racks is folded, the two storage racks can be combined into a whole, making the storage space larger and the storage more convenient.
