Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, specifically a mobile fire extinguisher cart. Background Technology

[0002] Fire extinguishers are key fire-fighting equipment for extinguishing initial fires and are widely used in various places such as factories, warehouses, parking lots, shopping malls, and hotels.

[0003] Currently, common fire extinguishers are mainly divided into two categories: hand-held fire extinguishers and wheeled fire extinguishers. Wheeled fire extinguishers usually have a structure with two large wheels, which makes them less capable of crossing obstacles. They require a high degree of flatness of the road surface and are prone to getting stuck when encountering uneven ground, small ditches, or thresholds, making it difficult to pass smoothly. Most wheeled fire extinguishers can only carry one extinguishing agent cylinder at a time, which cannot meet the needs of scenarios where multiple fire extinguishers need to be used continuously. Utility Model Content

[0004] The technical solution adopted by this utility model is as follows:

[0005] A portable fire extinguisher cart includes a mobile frame, with two mobile frames having rotating shafts rotatably connected to their front and rear ends, extending laterally. The left and right ends of the rotating shafts extend through the mobile frames, and rotating brackets are fixedly fitted onto the outer walls of both ends of the rotating shafts. The rotating brackets are triangular star-shaped, with three wheels rotatably mounted on their three ends. The tops of the front and rear ends of the mobile frames are fixedly connected to the bottom of a diagonal support frame. The tops of the two diagonal support frames are inclined to opposite sides, and support plates are vertically fixedly connected to the bottoms of the opposite side walls of the two diagonal support frames. A top plate is fixedly connected between the tops of the two diagonal support frames. A placement seat is fixedly connected to the top of each support plate. The placement seat is U-shaped, with an opening in each placement seat that extends upwards through the top of the placement seat. A fire extinguisher is placed inside the slot, with the bottom of the fire extinguisher located on the top of the support plate. A push handle is fixedly connected to the center of the top of the top plate, extending horizontally forward to the left and right sides.

[0006] One side edge of the placement base is fixedly connected to one end of two straps, which are distributed vertically. Two buckles are embedded in the other side edge of the placement base, and the movable ends of the two straps are respectively engaged with the other ends of the two buckles.

[0007] The beneficial effects of this utility model are:

[0008] With its triangular star-shaped rotating bracket and multiple moving wheels, this vehicle offers superior obstacle-crossing ability and ground adaptability compared to existing two-wheeled handcarts. The alternating contact of the wheels with the ground allows it to more effectively handle complex terrains such as uneven surfaces, small ditches, or stairs, resulting in smoother movement and less susceptibility to getting stuck.

[0009] The combination of slots, straps, and buckles provides double protection. The slots restrict movement at the bottom, while the straps restrain the upper part of the bottle, effectively preventing the fire extinguisher from tipping over, colliding, or even falling during rapid movement or bumpy conditions, thus ensuring safety during transportation.

[0010] The two placement seats can carry two fire extinguishers at the same time, which is very important for fighting initial fires. When one fire extinguisher is used up, the second one can be used immediately without returning to the storage point, thus improving fire fighting efficiency. Attached Figure Description

[0014] See attached document Figure 1-2 A portable fire extinguisher cart includes a mobile frame 1. The front and rear ends of the two mobile frames 1 are rotatably connected to a rotating shaft 2, which extends laterally. The left and right ends of the rotating shaft 2 extend through the mobile frame 1. Rotating brackets 3 are fixedly fitted onto the outer walls of the left and right ends of the rotating shaft 2. The rotating brackets 3 are triangular star-shaped frames, and three ends of the rotating brackets 3 are rotatably mounted with wheels 4. The tops of the front and rear ends of the mobile frame 1 are fixedly connected to the bottom of a diagonal brace 5. The tops of the two diagonal braces 5 are inclined to opposite sides. The bottom of the opposite side walls of the support frame 5 are vertically fixed with a support plate 6. The top of the two diagonal support frames 5 is fixedly connected with a top plate 7. The top of the two support plates 6 is fixedly connected with a placement seat 8. The placement seat 8 is U-shaped. Each placement seat 8 has an opening as a slot 9. The slot 9 extends upward through the top of the placement seat 8. The slot 9 contains a fire extinguisher 10. The bottom of the fire extinguisher 10 is located at the top of the support plate 6. The top center of the top plate 7 is fixedly connected with a push handle 13. The push handle 13 extends horizontally forward to the left and right sides.

[0015] One side edge of the placement seat 8 is fixedly connected to one end of two straps 11, which are distributed vertically. Two buckles 12 are embedded in the other side edge of the placement seat 8, and the movable ends of the two straps 11 are respectively engaged with the other ends of the two buckles 12.

[0016] The buckle 12 is a prior art device, and its structure will not be described in detail.

[0017] Working process and principle:

[0018] The fire extinguisher 10 is placed vertically on the tray 6, with the lower part of its body embedded in the slot 9 of the placement seat 8. The slot 9 serves to initially position and prevent slippage. Then, the movable end of the strap 11 is pulled out, wrapped around the body of the fire extinguisher 10, and fastened into the buckle 12 on the other side. The two straps 11 work together to firmly bind the fire extinguisher 10 to the placement seat 8, preventing it from tipping over or falling off during transportation.

[0019] When needed, the operator can quickly untie the connection between the strap 11 and the buckle 12, and directly pull the fire extinguisher 10 upward from the slot 9 to perform the fire extinguishing operation. The whole process is quick and simple and will not delay the fire extinguishing opportunity.

[0020] The diagonal brace 5 connects the movable frame 1 and the top plate 7, forming a sturdy triangular support structure, which greatly enhances the rigidity and stability of the overall frame, enabling it to withstand the weight of the fire extinguisher and vibrations during transportation.

[0021] The operator stands behind the push handle, holds the push handle 13 with both hands, and can push the entire device forward like a wheelbarrow, or pull it backward as needed.

[0022] During the pushing process, if it encounters stairs, the rotating bracket 3 fixed to the rotating shaft 2 will rotate accordingly, and the moving wheels 4 installed at its three ends will contact the steps in turn, forming a continuous and smooth rolling.

[0023] This star-shaped wheel design ensures good maneuverability and stability on both flat and uneven surfaces, easily transporting the fire extinguisher 10 to the optimal location near the fire scene.

[0024] The design of the triangular star-shaped rotating bracket 3 combined with multiple moving wheels 4 gives it a superior obstacle-crossing ability and ground adaptability compared to the current two-wheeled handcarts. The wheels alternately contact the ground, which can more effectively deal with complex terrains such as uneven roads, small ditches or stairs, making the movement more stable and less likely to get stuck. It can also hold two fire extinguishers 10.

[0025] The combination of the slot 9, strap 11, and buckle 12 provides double protection. The slot restricts movement at the bottom, while the strap restrains the upper part of the bottle, effectively preventing the fire extinguisher from tipping over, colliding, or even falling during rapid movement or bumpy conditions, thus ensuring safety during transportation.

[0026] The two placement seats 8 can carry two fire extinguishers 10 at the same time, which is very important for fighting initial fires. When one fire extinguisher 8 is used up, the second one can be used immediately without returning to the storage point, thus improving fire extinguishing efficiency.
