[0021] Advantages:

[0022] Compared with the prior art, the present application has the following advantages:

[0023] The present application comprises a fixed ring fixedly installed in the middle of the tank body, four lifting frames slidably sleeved on the circumference of the fixed ring at equal angles, a support block fixedly installed on the top of the lifting frame, a top plate fixedly installed on the top of the tank body, a pressing plate slidably installed on the top of the top plate and controlled by a torsion spring, a reset top block on the inner side of the pressing plate to keep the pressing plate horizontal, a support plate fixedly connected with the top plate at the bottom of the pressing plate through a top rod on the top of the support block, and the support block with the pressing plate sinking elastically supported by the top rod.

[0024] This invention features fixed rods at equal angles at the bottom of the nozzle, with lifting plates slidably installed between adjacent fixed rods. A sliding groove is formed on the side wall of the nozzle, and the lifting plates are slidably engaged within the groove. Four lifting plates are then fixedly connected via connecting rings, which are fixed to the bottom of the lifting frame. When the fire extinguishing device is not suspended, the lifting plates enclose the heat-sensing glass tube, protecting it. When the fire extinguishing device is suspended at the bottom of the mounting plate, the lifting plates move upwards along with the lifting frame, exposing the heat-sensing glass tube. Upon heating, the glass tube expands and cracks, releasing the powder from the canister. During transportation and storage, the lifting plates effectively protect the heat-sensing glass tube.

A sealing gasket is snapped into the bottom of the limiting ring, and the bottom of the sealing gasket is supported by a heat-sensing glass tube. The bottom end of the heat-sensing glass tube is supported on the top of the spray head. When the top plate is suspended to the bottom of the hanging plate, the lifting plate rises with the lifting frame and is located in the middle of the heat-sensing glass tube. This guides and concentrates the powder sprayed from the nozzle. Then, the cone shape at the top of the spray head spreads the powder evenly in all directions. This concentrates the powder while allowing it to be sprayed evenly in all directions, thus improving the fire extinguishing effect. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] like Figures 1 to 8 As shown, the present invention provides a suspended dry powder fire extinguishing device, including a tank body 1 and a hanging plate 6. A top plate 2 is fixedly installed on the top of the tank body 1. A lifting groove 201 is opened at an equal angle on the top of the top plate 2. A support plate 8 is slidably installed inside the lifting groove 201. A pressure plate 802 is rotatably installed on the top of the support plate 8 through a torsion spring 801. A reset top block 803 is fixedly installed on the inner side of the pressure plate 802.

[0037] A fixing ring 4 is fixedly installed on the outer side of the middle part of the tank body 1. Four lifting frames 5 are slidably sleeved on the surface of the fixing ring 4 at equal angles. A support block 7 is fixedly installed on the top of the lifting frame 5. A top rod 701 is fixedly installed on the top of the support block 7. A support spring 702 is sleeved on the top rod 701. The top rod 701 is fixedly connected to the bottom of the support plate 8. The top of the support spring 702 is fixedly connected to the bottom of the top plate 2.

[0038] Four hooks 601 are fixedly installed at equal angles in a ring at the bottom of the hanging plate 6, and the hooks 601 are snapped into the bottom of the pressure plate 802.

[0039] When installation and disassembly are required, simply push the lifting frame 5 upwards to move the pressure plate 802 upwards and rotate it inwards under the action of the torsion spring 801. At this time, the hook 601 at the bottom of the hanging plate 6 can be attached to the top surface of the top plate 2. Then, under the action of the top rod 701, the lifting frame 5 sinks downwards, causing the pressure plate 802 to lock the hook 601. Conversely, the hook 601 can be directly removed from the top of the top plate 2, thus facilitating the installation and disassembly of the fire extinguishing device.

[0040] like Figure 1 , Figure 2 andFigure 7 As shown, the top and bottom of the fixed ring 4 are respectively provided with a push ring 501 and a reinforcing ring 502, both of which are fixedly installed on the four lifting frames 5.

When the fire extinguishing device is not suspended, the lifting plates 306 will wrap the temperature-sensitive glass tube 304 on the inner side at this time, which can protect the temperature-sensitive glass tube 304. When the fire extinguishing device is suspended at the bottom of the hanging plate 6, the lifting plates 306 will move upward by a distance with the lifting frames 5 at this time. At this time, the lifting plates 306 will leak out the temperature-sensitive glass tube 304. The temperature-sensitive glass tube 304 will expand and break after being heated, so that the powder can be sprayed out of the tank body 1. In the process of transportation and storage, the lifting plates 306 can protect the temperature-sensitive glass tube 304.
