Technical Field

[0001] The utility model relates to the technical field of fire extinguishing devices, in particular to a heptafluoropropane fire extinguishing device for preventing mis-starting. Background Art

[0002] Heptafluoropropane fire extinguishing device is a fire extinguishing device with high fire extinguishing efficiency. The heptafluoropropane fire extinguishing device is filled with a fire extinguishing agent of heptafluoropropane gas. The heptafluoropropane fire extinguishing agent in the heptafluoropropane fire extinguishing device is a colorless, odorless, non-conductive, and non-secondary polluting gas. It has the characteristics of cleanliness, low toxicity, good electrical insulation and high fire extinguishing efficiency. In particular, it has no damage to the ozone layer and has a relatively short residual time in the atmosphere. Its environmental protection performance is significantly better than that of halogenated hydrocarbons. It is a clean gas fire extinguishing agent that has been successfully researched and developed;

[0003] After searching, a Chinese patent with announcement number CN219878993U discloses a heptafluoropropane fire extinguisher. The utility model discloses a heptafluoropropane fire extinguisher, including a fire extinguisher bottle and a stabilizing mechanism. A bottle head valve is arranged on the top of the fire extinguisher bottle. The stabilizing mechanism includes a mounting ring, a support rod, a stabilizing plate, a mounting bolt and an adjusting component. The mounting ring is sleeved on the fire extinguisher bottle. Two support rods are symmetrically mounted on the surface of the mounting ring. Two L-shaped stabilizing plates are respectively located on the front and rear surfaces of the mounting ring. An adjusting component is arranged between the upper end of the stabilizing plate and the mounting ring. A mounting bolt is arranged at the lower end of the stabilizing plate. The utility model combines the fire extinguisher bottle and the stabilizing mechanism. Compared with the clamp installation, the utility model can adapt to fire extinguisher bottles of different sizes, increase the installation and use range of the stabilizing mechanism, and further support and stabilize the fire extinguisher bottle to avoid deformation and cracking of the connection between the fire extinguisher bottle and the external connecting pipe due to external force shaking, thereby increasing the installation and use stability of the fire extinguisher bottle.

[0025] The following is combined with Figure 1-4 The utility model is further described.

[0026] In order to solve the problems existing in the background technology, the present application proposes the following technical solution: a heptafluoropropane fire extinguishing device to prevent mis-startup.

[0027] The specific technical solution includes a fire extinguisher body 1 and an anti-misstart clamping assembly 2;

[0028] like Figure 1-4As shown, the fire extinguisher body 1 can extinguish the fire at the location of the fire, and can protect the safety of objects and people. A pressure gauge 101 is fixedly installed on the top of the fire extinguisher body 1. The pressure gauge 101 can monitor the pressure value inside the fire extinguisher body 1, which is convenient for observing whether the fire extinguisher body 1 is normal. A safety pin 102 is penetrated through the top side wall of the fire extinguisher body 1. The safety pin 102 can keep the fire extinguisher body 1 in a closed state. The anti-misstart clamping assembly 2, the fire extinguisher body 1 is clamped in the anti-misstart clamping assembly 2, the anti-misstart clamping assembly 2 is used to protect the starting device of the fire extinguisher body 1, the anti-misstart clamping assembly 2 includes a fixed box 201, a top cover 202, a limit plate 203, a spring 204 and a block 205, and the top cover 202 is welded on the top of the fixed box 201. The top cover 202 can limit the block 205. A limiting plate 203 is welded inside the fixed box 201. Two limiting plates 203 are provided, and the two limiting plates 203 are arranged opposite to each other. One end of the spring 204 is fixedly connected to the inner side wall of the fixed box 201, and the other end of the spring 204 is fixedly connected to the block 205. The block 205 is slidably connected to the fixed box 201, the top cover 202 and the limiting plate 203. There are two springs 204 and two blocks 205. The two springs 204 and the two blocks 205 are arranged opposite to each other. One block 205 is slidably connected to one limiting plate 203. Both the two blocks 205 are triangular, and the triangular tips of the two blocks 205 are opposite to each other. A slide groove 206 is provided on the bottom surface of the fixed box 201, and the fire extinguisher body 1 is snapped into the slide groove 206.

[0029] Pick up the upper and lower handles of the fire extinguisher body 1, hold the handles tightly, and the safety pin 102 of the fire extinguisher body 1 cannot be pulled. The air outlet pipe of the fire extinguisher body 1 faces the slide groove 206, and the bottleneck is stuck in the slide groove 206. Push the fire extinguisher body 1, and the pressure gauge 101 and the safety pin 102 of the fire extinguisher body 1 respectively squeeze the outward inclined surfaces of the blocks 205 on both sides. After the blocks 205 are squeezed, the spring 204 is squeezed, and the spring 204 contracts to generate elastic force. The spring 204 gives thrust to the blocks 205, and the two blocks 205 move away from each other. The distance between the two blocks 205 increases. When the pressure gauge 101 and the safety pin 102 pass over the tip of the block 205, the spring 204 Push the card block 205, the card block 205 resets, and the safety pin 102 is protected in the fixing box 201, which can prevent the safety pin 102 from being pulled out by mistake. When the fire extinguisher body 1 needs to be used, hold the handle tightly and pull the handle away from the fixing box 201. The handle drives the fire extinguisher body 1 to slide in the slide groove 206, and the fire extinguisher body 1 drives the pressure gauge 101 and the safety pin 102 to move. The pressure gauge 101 and the safety pin 102 squeeze the inward inclined surface of the card block 205. After the card block 205 is squeezed, the spring 204 is squeezed. According to the above steps of the card block 205 squeezing the spring 204, the two card blocks 205 move away from each other, so that the fire extinguisher body 1 can be quickly taken out and used.
