Description

Cannon machinery percussion safety device

Technical Field

The utility model belongs to the technical field of artillery, and particularly relates to an artillery mechanical firing safety device.

Background

The gun can be fired by operating a mechanical firing handle under any condition after ammunition filling is completed. In the course of daily training and exercise, the situation that shooting is performed without receiving a shooting instruction due to tension of a fighter, pulling of clothes or other misoperation occurs, and the situation is very dangerous. Therefore, a gun mechanical firing safety device needs to be designed, false firing is avoided, and the safety of equipment use is improved.

Disclosure of Invention

First, the technical problem to be solved

The utility model aims to solve the technical problems that: the gun is easy to be wrongly triggered, and the safety is affected.

(II) technical scheme

In order to solve the technical problems, the utility model provides an artillery mechanical firing safety device, which comprises a safety piece 1, a fixed pin shaft 2 and a retainer ring 3; the safety piece 1 is of a sheet structure, one side of the safety piece is provided with a cylinder part, the side opposite to the cylinder part is provided with a bending part, and the bending part is provided with an arc surface; the fixed pin shaft 2 is fixed at the adjacent position of the firing handle, and the cylinder part of the safety disc 1 is sleeved on the fixed pin shaft 2; the check ring is arranged at the end part of the fixed pin shaft 2; the side of the firing handle is provided with a groove which is matched with the arc surface on the safety disc 1.

The novel anti-theft device further comprises a bolt and a gasket 4, wherein the bolt and the gasket 4 are arranged on the outer side of the retainer ring 3.

After the arc on the safety piece 1 is attached to the upper groove of the firing handle, the firing handle cannot fire downwards.

Detailed Description

For the purposes of clarity, content, and advantages of the present utility model, a detailed description of the embodiments of the present utility model will be described in detail below with reference to the drawings and examples.

As shown in fig. 1 to 6, the gun mechanical firing safety device of the present embodiment includes a safety plate 1, a fixed pin shaft 2, a retainer ring 3, and a bolt and washer 4.

The safety piece 1 is of a sheet structure, one side of the safety piece is provided with a cylinder part, the side opposite to the cylinder part is provided with a bending part, and the bending part is provided with an arc surface.

The fixed pin shaft 2 is fixed at the adjacent position of the firing handle, and the cylinder part of the safety disc 1 is sleeved on the fixed pin shaft 2; the check ring is arranged at the end part of the fixed pin shaft 2 and used for blocking the safety piece 1, and the bolt and the gasket 4 are arranged at the outer side of the check ring 3 and used for fixing the check ring 3 on the fixed pin shaft 2.

Correspondingly, the side surface of the firing handle is provided with a groove which is matched with the arc surface on the safety disc 1.

The working process comprises the following steps: the safety plate 1 is stirred upwards, and after the arc on the safety plate 1 is attached to the groove on the firing handle, the firing handle cannot be fired downwards, so that the safety effect is achieved. When the safety piece is required to be released, the safety piece is stirred to the lower part, so that the firing handle can be fired downwards, and the safety is released.

The foregoing is merely a preferred embodiment of the present utility model, and it should be noted that modifications and variations could be made by those skilled in the art without departing from the technical principles of the present utility model, and such modifications and variations should also be regarded as being within the scope of the utility model.
