Description

Technical Field

[0001] The utility model relates to the technical field of fire fighting devices, in particular to a fire fighting extinguishing bomb launching device. Background Art

[0002] Fire extinguishing bombs usually only extinguish fires through the dry powder contained inside. Not only is the fire extinguishing effect poor, but existing fire extinguishing bombs can only extinguish surrounding flames, and the fire extinguishing range is small, and they are not suitable for fires in a larger range.

[0003] China's authorization announcement number CN210433875U discloses a shoulder-supported fire-fighting extinguishing device, the rear end of the cylinder body of the push-bullet cylinder is detachably connected with a high-pressure gas cylinder, the internal chamber of the high-pressure gas cylinder and the push-bullet cylinder are connected, and a switch valve is arranged on the pipeline connected between the high-pressure gas cylinder and the internal chamber of the push-bullet cylinder, the gripping handle is vertically fixed on the cylinder body of the push-bullet cylinder, the trigger plate is elastically rotated and connected to the gripping handle by a torsion spring, and the upper end of the trigger plate is connected to the switch valve by a connecting rod mechanism; the internal chamber of the push-bullet cylinder is provided with a push-out mechanism, the front end of the push-bullet cylinder is fixedly connected with a cartridge, the fire-extinguishing bomb is stuck in the cartridge, and one end of the push-out mechanism extends into the cartridge and abuts against the bottom of the fire-extinguishing bomb. The purpose of the utility model is to solve the problem that the fire-extinguishing bomb cannot be launched to a far position in the prior art, the fire-extinguishing range is small, and it is not suitable for a large range. The technical effect achieved is: the long-distance launch of the fire-extinguishing bomb by artificial shoulder support is realized, and the fire-extinguishing effect is good.

[0004] However, the device has the following defects when in use: since the device uses a single-shoulder shoulder-supported launch method to launch fire-fighting bombs, and uses a high-pressure gas cylinder and a bullet-pushing cylinder to drive the launch, a large recoil will be generated during the launch, and the recoil is completely absorbed by the firefighter's single shoulder, which will cause pain to the firefighter's single shoulder, and the large recoil absorbed by the single shoulder is likely to cause the launcher to deviate from the track to a large extent. In view of the above defects: To this end, we propose a fire-fighting bomb launcher. Utility Model Content

[0016] Beneficial Effects

[0018] 1. The fire-fighting bomb launching device, by setting a lifting structure, places one end of the first lifting frame and the second lifting frame on the two shoulders of the firefighter respectively, and the other end is placed on the chest, and then uses the first restraint belt and the second restraint belt to fix the first lifting frame and the second lifting frame. When the fire-fighting bomb launching tube launches the fire-fighting bomb, the firefighter can hold the handle, and the recoil will be transmitted to the first lifting frame and the second lifting frame by the support frame and the oblique support respectively. Compared with the prior art, the device uses the shoulders and chest to share the recoil transmitted by the first lifting frame and the second lifting frame, and the hand-held handle can share the recoil transmitted by the handle, and can also reduce the shaking of the fire-fighting bomb launching tube, thereby reducing the pain caused by the recoil of the firefighter.
