Technical Field

The invention relates to the field of aviation lifesaving, in particular to a fixing device for pulling out lifesaving ammunition of an airplane from a sealed cavity and a using method thereof.

Background

Because the ammunition shell and the cavity are sealed by the sealing rubber ring, the contact surface of the ammunition shell and the cavity is tighter, the force application requirement is larger when the lifesaving ammunition is pulled out from the sealing cavity, the shape of the shell of the originally used ammunition locking shell is not beneficial to applying force by hand, and the pulling effect is not good. And the bullet locking machine is pulled out only by two claws to be fixed with the bottom edge 2 of the life-saving ammunition, so that the bullet locking machine is easy to separate from the ammunition when pulled out. And moreover, a firing pin mechanism is arranged in the ammunition locking machine and corresponds to the primer part of the ammunition, if the firing pin mechanism in the ammunition locking machine is released due to failure in the force application process, the possibility of ammunition fire escape accidents can be caused, and a large safety risk exists.

Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further explained below.

As shown in fig. 1 to 8, the fixing device for pulling out the life saving ammunition of the airplane from the sealed cavity comprises:

the fixing device is matched with the bottom edge 2 of the ammunition shell 3 and is used for uniformly transmitting force to the ammunition, so that the ammunition shell 3 can be reliably pulled out of the sealed cavity;

the portable device is matched with the fixing device, so that the fixing device is more reliably connected with the ammunition shell 3, and the problem of pulling out and disengaging cannot occur in the force application process.

The invention avoids the defect of inconvenient force application by using a bullet locking machine pulling mode in the traditional method, and thoroughly solves the problem that the ammunition is easy to drop off in the bullet locking machine pulling mode. The size of the fixing device is reduced as much as possible by considering the requirement of the use position on the size of the pulling device, so that the use feeling is better.

The force application mode of the handle is utilized, an operator can conveniently increase the required force application lever device to operate, the stop pin is installed at the proper position of the groove 4 at the bottom of the fixing device through a through hole, the possibility that ammunition is separated from the groove can be thoroughly solved, and the pulling operation is safer.

The reason for sinking a portion of the bottom plane of the fixture is to solve the problem of interference with the fixture when the individual ammunition primer planes will bulge out of the ammunition planes.

The fixing device comprises a groove 4 which is arranged on the fixing device and can be uniformly meshed with the bottom edge 2 of the ammunition shell 3 to transmit force to ammunition, a primer groove 5 which is separated from the primer 1 arranged on the bottom edge 2 and prevents the primer 1 from contacting with the ammunition shell 3, a plurality of groups of stop pin mounting holes 6 which are arranged on the side end surface of the fixing device and are matched with the stop pins to prevent ammunition from slipping from the groove 4 in the force application process, and a handle mounting hole 7 which is arranged on the upper end surface of the fixing device and is matched with a hand-held device to ensure that the connection is more reliable and the pulling-out cannot occur in the force application process.

The primer groove 5 made on the fixing device can effectively prevent the possibility that the primer contacts with the fixing device, and ensure the safety of ammunition when force is applied. The safety accident caused by the extrusion of the ammunition primer is prevented.

The groove 4 in the fixing device can be completely contacted with the ammunition bottom edge 2, so that force can be uniformly transmitted to the ammunition shell 3, and the ammunition can be smoothly pulled out of the sealed cavity; the problem that ammunition cannot slip from the groove 4 after being combined with the fixing device can be solved by the aid of the stop pin mounting holes 6 in the fixing device, so that pulling operation is safer, and the problem that clamping jaws and ammunition are easy to disengage and fall off when an original ammunition locking machine is used for pulling is solved.
