[0002] A fire extinguisher is a portable fire-fighting device used to extinguish initial fires. It contains a specific extinguishing agent, which is propelled by compressed gas to control or extinguish the fire. Fire extinguishers are typically used to quickly respond to small-scale fires, especially those common in homes, offices, vehicles, and public places. To facilitate easy movement on flat ground and in stairwells, wheeled fire extinguishers are particularly suitable for warehouses, workshops, gas stations, and similar locations. Users do not need to carry heavy loads, allowing for rapid deployment of the fire-fighting equipment; therefore, wheeled fire extinguishers are necessary.
[0003] Wheeled fire extinguisher cylinders can be divided into several types, namely dry powder wheeled fire extinguishers, carbon dioxide wheeled fire extinguishers, and foam wheeled fire extinguishers. These different types of wheeled fire extinguishers are suitable for specific fire types and location needs, and can be selected according to the fire risk environment. Among them, dry powder wheeled fire extinguishers use dry powder extinguishing agents and are suitable for extinguishing solid, liquid, and gas fires. Dry powder has a highly efficient fire extinguishing effect and is suitable for flammable places such as petrochemical plants and warehouses.
[0004] However, a significant problem exists in existing technologies: when placing the cylinders on a trolley, they are prone to misalignment or detachment. This not only affects the stability of the fire extinguisher but can also cause inconvenience in emergency situations, increasing fire safety hazards. Therefore, improving the stability of wheeled fire extinguisher cylinders to prevent misalignment and detachment during movement has become an important direction for current technological development.

A locking block 9 is fixedly connected to one side of the limiting plate 6, engaging with a slot 4. The locking block 9 effectively locks the fire extinguisher bottle 2, preventing misalignment or detachment during movement. A pull ring 10 is fixedly connected to the outer wall of the limiting plate 6. The pull ring 10 allows for quick release of the lock when needed, improving operational convenience. The connecting assembly includes a support ring 3. The top of ring 3 is fixedly connected to the bottom of fire extinguisher bottle 2. The design of the support ring 3 ensures the stable connection between fire extinguisher bottle 2 and cart 1. At the same time, a slot 4 is provided inside to provide fitting space for the locking block 9. The reset component includes a first spring 8. The function of the first spring 8 is to provide restoring force so that the telescopic rod 7 can automatically return to its position after use, ensuring the stability and reliability of the fire extinguisher. One end of the first spring 8 and one end of the telescopic rod 7 are fixedly connected to the other side of the limiting plate 6. The other end of the first spring 8 and one end of the telescopic rod 7 are fixedly connected to the inside of the housing 5, forming an effective reset mechanism.
[0033] Specifically, during the installation and locking operation of the fire extinguisher bottle 2, the fire extinguisher bottle 2 is first securely placed in the designated position on the cart 1 by the support ring 3 at its bottom, ensuring that the fire extinguisher bottle 2 is in a stable state. Next, the locking block 9 located inside the housing 5 accurately engages with the slot 4 on the cart 1, forming a connection between the fire extinguisher bottle 2 and the cart 1. To maintain the stability of the locking block 9 inside the housing 5, the locking block 9 is limited and positioned by the limiting plate 6, ensuring that the locking block 9 will not move arbitrarily. Furthermore, the first spring 8 provides continuous tension support for the locking block 9, thereby firmly embedding the locking block 9 into the slot 4, preventing it from falling off or shifting. This design effectively locks the fire extinguisher bottle 2, ensuring its safety and stability on the cart 1.
[0034] Reference Figure 3The trolley 1 has a fixedly connected semi-ring 11 inside. One end of semi-ring 11 is rotatably connected to semi-ring 2 12. The design of semi-ring 11 allows the two semi-rings to be flexibly connected and disassembled, facilitating the installation and removal of the fire extinguisher bottle 2. The other end of semi-ring 11 is fixedly connected to a connecting block 13. The connecting block 13 has a locking groove 14 inside, which provides a secure fixing position for the connecting semi-rings, ensuring that the fire extinguisher bottle 2 will not accidentally fall off during use. The other end of semi-ring 2 12 is fixedly connected to a connecting block 2 15. The setting of connecting block 2 15 enhances the stability of the semi-rings, ensuring that the entire structure has good support when bearing load. The connecting block 2 15 has symmetrically arranged connecting plates 16 slidingly connected inside. The design of connecting plates 16 allows them to be flexibly adjusted as needed to accommodate fire extinguisher bottles 2 of different sizes. One side of connecting plate 16 is fixed. The connection includes a second locking block 17 and a pressure post 18. The second locking block 17 engages with the locking groove 14. The function of the second locking block 17 is to effectively lock the connection between the connecting plate 16 and the half ring, enhancing safety and preventing accidental detachment. The pressure post 18 allows users to release the lock with simple operation, facilitating the quick disassembly of the fire extinguisher bottle 2. The second connecting block 15 has a telescopic rod 19 inside. The design of the telescopic rod 19 allows for effective adjustment of the tightening force of the half ring during use. The outer wall of the telescopic rod 19 is fitted with a second spring 20. The function of the second spring 20 is to provide restoring force, ensuring that the connecting block can quickly return to its initial position after use, maintaining the stability of the connection. Both ends of the telescopic rod 19 and the second spring 20 are fixedly connected between the connecting plate 16, forming an effective support and reset mechanism, further improving the safety and convenience of the fire extinguisher bottle 2 on the cart 1.
[0035] Specifically, when it is necessary to disassemble the fire extinguisher bottle 2, simply press the pressure rod 18. This operation will cause the connecting plate 16 to separate the locking block 17 from the locking groove 14, allowing the locking block 17 to quickly disengage from the locking groove 14. This action directly releases the connection between the first half-ring 11 and the second half-ring 12, thus smoothly separating the second half-ring 12 from the first half-ring 11, facilitating the removal of the fire extinguisher bottle 2. After releasing the pressure rod 18, the telescopic rod 19 pushes the locking block 17 to automatically reset through its tension, ensuring that the locking block 17 returns to its initial position. This design achieves the effect of convenient disassembly of the fire extinguisher bottle 2, simplifies the operation of taking out and putting in the fire extinguisher bottle 2, and ensures the reliability of the structure during reset.
[0036] Working principle: When using this wheeled fire extinguisher cylinder, the first step is to lock the fire extinguisher cylinder 2. The fire extinguisher cylinder 2 is placed on the cart 1 via the bottom support ring 3. Then, the locking block 9 inside the housing 5 is inserted into the locking groove 4 to connect the fire extinguisher cylinder 2 to the cart 1. The locking block 9 is limited within the housing 5 by the limiting plate 6 and supported by the tension of the first spring 8, making it difficult for the locking block 9 to disengage from the locking groove 4, thus achieving the effect of locking the fire extinguisher cylinder 2. When it is necessary to disassemble the half ring 11 and half ring 12 of the fire extinguisher cylinder 2, simply press the pressure column 18, which will then drive the locking block 17 to separate from the locking groove 14 through the connecting plate 16, thereby separating the half ring 12 from the half ring 11, and the fire extinguisher cylinder 2 can be removed. Releasing the pressure column 18 will push the locking block 17 to reset under the tension of the telescopic rod 19, achieving the effect of facilitating the disassembly of the fire extinguisher cylinder 2.
[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
