[0002] Hanging dry powder fire extinguishers are a common type of fire-fighting equipment, widely used in various fields such as construction, industry, and transportation. They are used to extinguish initial fires. Dry powder fire extinguishers are generally composed of a steel cylinder, nozzle, pressure gauge, and operating valve. Dry powder is the main extinguishing agent and has a good extinguishing effect, capable of extinguishing solid, liquid, and gas fires.

[0003] Traditional hanging dry powder fire extinguishers consist of a cylinder, nozzle, pressure gauge, operating valve, and hook or bracket. The working principle is to spray dry powder onto the fire source by compressed gas, isolating oxygen and thus extinguishing the fire. The compressed gas propels the dry powder out, and the extinguishing dry powder inhibits the flame through physical and chemical means. It is suitable for various types of fires. The fire extinguisher is hung on the wall for easy access in an emergency.

[0004] Traditional suspended dry powder fire extinguishers are usually fixed to the wall with hooks. However, due to the insufficient stability of the hooks, they may loosen due to vibration, external impact, or prolonged use. This can cause the fire extinguisher to fall and become unusable in time, affecting its efficiency in emergency situations. Therefore, a suspended dry powder fire extinguisher is proposed to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A suspended dry powder fire extinguisher includes a bottle body, a fixed base fixedly connected to the top of the bottle body, a rotating ring rotatably connected to the inner wall of the fixed base, a hook fixedly connected to the top of the rotating ring, a connecting shaft rotatably connected to the outer wall of the hook, baffles fixedly connected to both ends of the connecting shaft, a spring fixedly connected to one side of the baffle, a stop head fixedly connected to the outer wall of the hook, and an adjustment component provided at the bottom of the bottle body.

[0008] As a further description of the above technical solution:

[0009] The adjustment component includes a connection port, the inner wall of which is threadedly connected to a nozzle connector, and the inner wall of the nozzle connector is fixedly connected to a temperature sensing ball.

[0010] As a further description of the above technical solution:

[0011] A connecting block is fixedly connected to the bottom of the nozzle connector, and a rotating nozzle is rotatably connected to the bottom of the temperature sensing ball.

[0012] As a further description of the above technical solution:

[0013] A pressure gauge is fixedly connected to the outer wall of the nozzle connector, and a pressure regulating valve is threadedly connected to the inner wall of the nozzle connector.

[0014] As a further description of the above technical solution:

[0015] One end of the spring is fixedly connected to the inner wall of the hook, and the outer wall of the baffle is in contact with the outer wall of the stop head;

[0016] As a further description of the above technical solution:

[0017] The bottom of the temperature-sensing ball is fixedly connected to the inner wall of the connecting block, and the top of the rotating nozzle is fixedly connected to the inner wall of the connecting block.

[0018] As a further description of the above technical solution:

[0019] The outer wall of the connection port is fixedly connected to the inner wall of the bottom of the bottle, and the temperature sensing ball is made of glass.

[0020] As a further description of the above technical solution:

[0021] The cross-section of the baffle is I-shaped, and the bottle body is made of aluminum alloy.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, by pushing the baffle inward, the baffle and the connecting shaft can rotate on the hook. The baffle and the connecting shaft rotate together, compressing the spring during the rotation. The spring force pushes the baffle back to its original position through the reaction force, realizing the self-locking function. By blocking the baffle head, excessive displacement of the baffle can be prevented, effectively locking the hook and preventing the device from falling off during use, which would cause the device to malfunction.

[0024] 2. In this utility model, when a fire occurs at the bottom of the hook, the temperature at the bottom of the hook reaches a certain value, and the liquid inside the temperature sensing ball expands due to heat and can break on its own. This allows the dry powder agent inside the hook to be sprayed out from the nozzle connector under the action of nitrogen. When the dry powder passes through the rotating nozzle, it can drive the rotating nozzle to perform transmission, thereby enabling the dry powder to rotate and spray, covering a larger area of ​​the fire source.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a suspended dry powder fire extinguisher, including a bottle body 1, which serves as the main container for storing extinguishing agent and compressed gas. It is the foundation of the entire fire extinguisher, ensuring the effectiveness and strength of the dry powder fire extinguisher. A fixed base 2 is fixedly connected to the top of the bottle body 1. The fixed base 2 ensures that subsequent components can be stably installed on the bottle body 1 through a fixed connection, playing a role in bearing and connecting. A rotating ring 3 is rotatably connected to the inner wall of the fixed base 2. The rotating ring 3 is rotatably connected to the inner wall of the fixed base 2, providing a certain degree of flexibility and allowing rotation around the bottle body 1. A hook 4 is fixedly connected to the top of the rotating ring 3. The hook 4 is a key component for suspending the fire extinguisher, allowing the fire extinguisher to be hung on a wall or bracket for easy access.

[0033] A connecting shaft 5 is rotatably connected to the outer wall of the hook 4. The connecting shaft 5 is used to connect subsequent components. Baffles 6 are fixedly connected to both ends of the connecting shaft 5. The baffles 6 prevent the hook 4 from loosening and ensure the stability of the fire extinguisher when it is hung. A spring 7 is fixedly connected to one side of the baffle 6. The spring 7 is used to provide the restoring force of the baffle 6 so that the hook 4 can be firmly hung on the installation position, making it easy to operate and preventing the fire extinguisher from falling off. One end of the spring 7 is fixedly connected to the inner wall of the hook 4. A stop 8 is fixedly connected to the outer wall of the hook 4, which can limit the movement range of the baffle 6 and prevent the baffle 6 from moving excessively. The outer wall of the baffle 6 contacts the outer wall of the stop 8. An adjustment component is provided at the bottom of the bottle body 1.

[0034] Reference Figures 1 to 3 The adjustment component includes a connection port 9, which serves as the connection point between the entire component and subsequent devices, providing connectivity. A nozzle connector 10 is threaded onto the inner wall of the connection port 9, ensuring a secure fit and preventing loosening or leakage. A temperature-sensing bulb 12 is fixedly connected to the inner wall of the nozzle connector 10, sensing changes in ambient temperature and automatically bursting when the temperature exceeds a set value. A connecting block 11 is fixedly connected to the bottom of the nozzle connector 10, further securing the entire component structure and ensuring stable connections between all parts. A rotating nozzle 13 is rotatably connected to the bottom of the temperature-sensing bulb 12. The rotating nozzle 13 can effectively adjust the spray direction or spray mode by rotating, thereby optimizing the spraying effect and meeting different needs. A pressure gauge 14 is fixedly connected to the outer wall of the nozzle connector 10. The pressure gauge 14 is used to monitor the pressure changes in the bottle 1 in real time to ensure that the operation is within a safe range and to avoid malfunctions or accidents caused by abnormal pressure. A pressure regulating valve 15 is threadedly connected to the inner wall of the nozzle connector 10. The pressure regulating valve 15 maintains the stability of the working pressure of the bottle 1 by adjusting the internal pressure, effectively preventing the pressure from being too high or too low, and ensuring the long-term safe operation of the equipment.

[0035] Working principle: By pushing the baffle 6 inward, the baffle 6 and the connecting shaft 5 can rotate on the hook 4. During the rotation, the baffle 6 can compress the spring 7 inward. The elastic force generated by the spring 7 during compression can push the baffle 6 in the opposite direction, so that the baffle 6 can self-lock. By blocking the stop head 8, the baffle 6 can be prevented from excessively deviating, effectively locking the hook 4 and preventing the device from falling off during use, which would cause the device to malfunction.

[0036] When a fire occurs at the bottom of hook 4, the temperature at the bottom of hook 4 reaches a certain value, and the liquid inside the heat-sensing bulb 12 expands due to heat and breaks on its own. This causes the dry powder agent inside hook 4 to be sprayed out from the nozzle connector 10 under the action of nitrogen. When the dry powder passes through the rotating nozzle 13, it can drive the rotating nozzle 13 to rotate and spray, covering a larger area of ​​the fire source and further improving the safety of the device.

[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.
