Embodiment Construction

[0020] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0021] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0022] It is to be understood that the terms "length", "width", "top", "bottom", "front", "rear", "left", "right", "vertical", "horizontal", "top" , "bottom", "inner", "outer" and other indicated orientations...

Abstract

The invention provides a method and device for ensuring in-chamber safety of small-caliber ammunition. The method comprises the steps that a the device used for ensuring the in-chamber safety is arranged in a small-caliber ammunition fuse, the device acts under the action of in-chamber recoil force in the shooting process for preventing a fuse isolating mechanism from moving, and then the fuse isolating mechanism is made in an isolated state; and after the ammunition is out of the chamber, the device is reset, and a restriction on the fuse isolating mechanism is removed. The device comprises a base, a limiting body, a safety pin, an elastic part, a containing groove, a first locating hole and a second locating hole, wherein a fastening part is arranged at one end of the containing groove, the elastic part enables the safety pin to be located in the containing groove or the containing groove and the first locating hole at ordinary times, and the safety pin compresses the elastic part to move under the action of the in-chamber recoil force to enable the first locating hole to be fixedly connected with the second locating hole in an inserted manner in the shooting process. According to the method and device for ensuring the in-chamber safety of the small-caliber ammunition, it is guaranteed that isolation cannot be removed through the fuse isolating mechanism in the chamber, and therefore an in-chamber explosion is avoided, and the in-chamber safety in the shooting process is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of ammunition safety control, and more specifically relates to a method and device for ensuring the safety in the bore of small-caliber ammunition. Background technique [0002] High safety is one of the basic requirements for ammunition. The ammunition must be designed to ensure the safety of the service process, launch process and ballistic trajectory. Since the fuze is responsible for making the ammunition act in a timely manner, the safety of the fuze has a great impact on the safety of the ammunition. has a vital impact. Small-caliber ammunition is limited by its own caliber. The fuze it is equipped with is small in size and the internal space of the fuze is very limited. It is difficult to design the safety mechanism used to ensure safety. It requires a simple structure and reliable function. If the fuze safety mechanism is in the chamber When the safety is completely released and the isolation mechan...
