Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguishing bombs, in particular to a fire extinguishing bomb anti-mistaken collision protection structure. Background Art

[0002] The fire extinguishing bomb has low concentration, high fire extinguishing efficiency and fast fire extinguishing speed, and is widely used in fire extinguishing in various places. The fire extinguishing bomb can be installed on drones or airplanes as a forest airdrop fire extinguishing bomb.

[0003] The existing announcement number is CN210159118U, and the name is a hand-thrown fire extinguishing bomb, including a bomb body, a detonating tube, a firing pin, an impact part, a safety ring and a safety spring. The detonating tube extends into the cavity of the bomb body and is fixedly connected to one end face of the bomb body. One end of the firing pin is fixedly connected to the impact part, and the other end extends into the interior of the detonating tube. The two ends of the safety ring are respectively connected to the bottom of the impact part and the end of the bomb body. The safety spring is sleeved on the firing pin between the impact part and the detonating tube. The impact part impacts downward to drive the firing pin to move downward and impact the detonating tube to explode and disperse the fire extinguishing material in the bomb body to extinguish the fire.

[0004] However, the fire extinguishing bomb itself lacks a structure for limiting the impact part, and uses a spring to support the impact part. When the top of the fire extinguishing bomb is accidentally hit and squeezed, the bomb body sinks inward and squeezes the impact part, causing the spring to deform, thereby causing the fire extinguishing bomb to explode, thereby reducing the safety of the fire extinguishing bomb. Utility Model Content

[0005] The utility model aims to provide a fire extinguishing bomb anti-accidental collision protection structure, aiming to improve the above-mentioned problem.

[0006] The utility model is achieved in this way:

[0007] A fire extinguishing bomb anti-accidental collision protection structure comprises a fire extinguishing bomb and a collision piece, the fire extinguishing bomb comprises a shell, the interior of the shell is hollow, and the hollow cavity of the shell is filled with fire extinguishing dry powder, the collision piece comprises a powder cartridge, the powder cartridge is inserted into the shell, and the powder cartridge is filled with a powder column, one end of the powder cartridge is provided with a protection piece, the protection piece comprises a spiral ring, the spiral ring is connected and fixed to the end of the powder cartridge, and the other end of the spiral ring is connected and fixed to a spiral barrel, a collision column is slidably inserted in the spiral barrel, and a firing pin is vertically fixed to the bottom end of the collision column, an external thread is provided on the outer circumferential surface of the collision column, and the external thread of the collision column is assembled with the thread of the spiral barrel, a spiral shell is connected and fixed at the center of one end of the shell, and the spiral shell is assembled with the spiral ring thread.

[0008] Furthermore, a spring is vertically sleeved on the collision column, and one end of the spring is fixed to an end surface inside the spiral ring.

[0009] Furthermore, a hole seat is vertically fixed at one end of the screw barrel, and a pin rod is inserted and slidably penetrated in the hole seat horizontally.

[0010] Furthermore, a pin shaft hole is horizontally opened on the outer circumferential surface of the collision column, and the pin shaft hole is plugged into the end of the pin rod.

[0011] Furthermore, a sliding hole plate is horizontally fixed on the pin rod, and a plug column is vertically slidably inserted on the sliding hole plate of the pin rod.

[0012] Furthermore, a positioning hole plate is horizontally fixed on the hole seat, and the positioning hole plate is vertically slidably plugged with the plug post.

[0013] Furthermore, a hanging hole plate is vertically fixed to the end of the cartridge case.

[0014] Compared with the prior art, the utility model has the following beneficial effects: in order to avoid accidental collision with the collision column on the fire extinguishing bomb during transportation, the collision column is rotated in the screw barrel at the end of the screw ring before use. When the external thread on the collision column is assembled with the screw barrel thread, the collision column cannot slide in the screw barrel, which effectively avoids the accidental collision and squeezing of the collision column to ignite the gunpowder column in the gunpowder barrel. The explosion of the gunpowder column causes the shell to rupture, causing the fire extinguishing dry powder to fly out to extinguish the fire, thereby improving the safety of the fire extinguishing bomb.

In use, in order to avoid accidental collision with the collision column 233 on the fire extinguishing bomb 1 during transportation, the collision column 233 is rotated in the screw barrel 232 at the end of the screw ring 231 before use. When the external thread 237 on the collision column 233 is threadedly assembled with the screw barrel 232, the collision column 233 cannot slide in the screw barrel 232, which effectively avoids accidental collision and squeezing of the collision column 233 in the later stage to ignite the gunpowder column 22 in the gunpowder cartridge 21. The explosion of the gunpowder column 22 causes the cartridge case 11 to rupture, causing the fire extinguishing dry powder to fly out to extinguish the fire, thereby improving the safety of the fire extinguishing bomb.

[0024] See also Figure 4 The screw barrel 232 has a hole seat 238 fixed vertically at one end, and a pin rod 24 is inserted and inserted in the hole seat 238 for horizontal sliding. A pin shaft hole 234 is horizontally opened on the outer circumferential surface of the collision column 233, and the pin shaft hole 234 is inserted into the end of the pin rod 24. A sliding hole plate is fixed horizontally on the pin rod 24, and a plug column 241 is vertically slidably inserted on the sliding hole plate of the pin rod 24. A positioning hole plate 242 is fixed horizontally on the hole seat 238, and the positioning hole plate 242 is vertically slidably inserted with the plug column 241. In order to further maintain the safety of the fire extinguishing bomb 1 during use, the pin rod 24 on the sliding hole seat 238 is inserted into the pin shaft hole 234 of the collision column 233, and then the sliding hole plate on the pin rod 24 is vertically slidably inserted with the plug column 241 into the positioning hole plate 242, thereby further limiting the collision column 233 from sliding in the screw barrel 232, thereby improving the safety of the fire extinguishing bomb.

[0025] See also Figure 5 A hanging hole plate 14 is vertically fixed to the end of the cartridge case 11 for later hanging with the delivery equipment.

[0026] Working principle: In order to avoid accidental collision with the collision column 233 on the fire extinguishing bomb 1 during transportation, the collision column 233 is rotated in the screw barrel 232 at the end of the screw ring 231 before use. When the external thread 237 on the collision column 233 is assembled with the screw barrel 232 thread, the collision column 233 cannot slide in the screw barrel 232, which effectively avoids accidental collision and squeezing of the collision column 233 in the later stage to ignite the gunpowder column 22 in the gunpowder cartridge 21, and the explosion of the gunpowder column 22 causes the shell 11 to rupture. During use, the collision column 233 is rotated so that the collision column 233 can slide in the screw barrel 232. When being released, the collision column 233 is forced to slide in the screw barrel 232, and the firing pin 235 at the end of the collision column 233 is inserted into the gunpowder column 22 in the gunpowder cartridge 21, so that the gunpowder column 22 explodes and the shell 11 ruptures, causing the fire extinguishing dry powder to fly out to extinguish the fire.
