Description

Technical Field

[0001] The invention belongs to the field of anti-firing safety devices, and in particular relates to an anti-firing safety fork for an aircraft gun pod. Background Art

[0002] In modern military aviation operations, the aircraft gun pod is one of the important weapons and equipment of the fighter, and the anti-firing safety plays a vital role in the ground-mounted aircraft gun target shooting. However, during the loading process of the aircraft gun pod and the target shooting process, how to safely and effectively avoid the accidental firing of the aircraft gun has always been a difficult problem that has plagued the relevant fields. In the prior art, the traditional mechanical locking device may be loosened due to vibration or other factors in a complex environment, and the simple electronic safety may fail in some extreme cases, such as electromagnetic interference or electronic system failure, which poses a high safety risk. After the overall structure of the aircraft gun pod is installed, the aircraft needs to be powered on before the aircraft gun is loaded. Check the gun charging and gun firing lines. Personnel are not allowed to move in front of the gun muzzle after the shells are loaded. Therefore, the power plug of the starter car is not disconnected from the aircraft after the power is turned on for the first time, and only the on-board power switch is turned off. During the loading process of the gun, the aircraft may generate an electrical signal because the power plug of the starter car is connected, causing the trigger brake lever to rotate and release the firing shaft. Under the action of the firing spring, the firing shaft hits the hammer, the hammer hits the firing pin, and the firing pin hits the shell primer, causing the gun to fire accidentally. In addition, when the gun shell is loaded and the shell needs to be ejected, and when determining whether the number of shells and the loading number are the same after the shell is fired, the gun may fire accidentally. Summary of the invention

[0003] In view of the above problems, the object of the present invention is to provide an anti-firing safety fork which can improve the operational safety of workers when loading and unloading aircraft cannon shells and verifying that the number of firings and the number of loadings of the aircraft cannon are consistent.

[0004] The present invention is achieved through the following technical solutions: A fire prevention safety fork for an aircraft gun pod comprises a safety fork, a connecting piece and a handle; the front end of the safety fork is U-shaped, and the rear end is connected to the handle through a connecting piece; the handle is a rectangular body; the safety fork is made of metal; the handle is made of wood; the U-shaped opening end of the safety fork is provided with an arc surface; the connecting piece and the handle are connected through a mortise and tenon structure; a step is provided at the connection between the safety fork and the connecting piece; and a reinforcing rib is provided at the connection between the connecting piece and the handle.

[0005] Beneficial effects of the present invention: The invention can limit the left and right movement of the key firing shaft in the firing process of the aircraft gun to hit the hammer, thereby preventing the accidental firing of the aircraft gun shells and improving the operating safety of workers when loading and unloading the aircraft gun shells and checking the consistency between the firing number and the loading number of the aircraft gun.
