Problems solved by technology

However, in the traditional firing mechanism in the fuze chamber, whether the firing pin is fixed and the firing cap recoils or the cap is fixed and the firing pin recoils, the accidental firing of the cap will ignite the subsequent agent along the established fire transmission path, causing the fuze to accidentally ignite. Fire and explode (or disable the fuze), posing a safety hazard

Embodiment Construction

[0012] A detailed and complete description will be made below in conjunction with the accompanying drawings of the present invention.

[0013] combine figure 1 , a kind of fuze in-bore ignition mechanism adopting the principle of detonator and space explosion-proof according to the present invention comprises a body 1, an acupuncture detonator 2, a detonator seat 3, a preload spring 4, and a fire tube; from the center of the bottom surface of the body 1 upwards There is a three-step stepped blind hole, which is the first stepped hole, the second stepped hole and the third stepped hole from top to bottom. In the stepped hole, the peripheral outer wall of the detonator seat 3 is in clearance fit with the wall of the second stepped hole, and a second-stage through hole is opened downward from the top surface of the detonator seat 3, and the fourth stepped hole and the fifth stepped hole are sequentially arranged from top to bottom. The acupuncture detonator 2 is fixed in the fif...

Abstract

The invention discloses an in-bore ignition mechanism of a fuze adopting the principle of detonator and space explosion-proof, comprising a body, an acupuncture detonator, a detonator seat, a pre-compressed spring, and a fire transmission tube, which includes a fire transmission tube shell, a powder transmission powder and a fire transmission tube. The cover sheet is provided with an upward firing pin in the center of the top surface of the fire transfer tube shell. The sensitive explosive element for ignition is a needle-punched detonator, and the needle-punched detonator is located on the detonator seat, which is a relatively moving part, while the firing pin located on the upper end of the fire tube shell is a fixed part, and a pressure relief space is formed between the body and the detonator seat. The preloaded spring can adopt two parallel structures to increase reliability, and the propellant is insensitive igniter boron / potassium nitrate. In the assembled state, the acupuncture detonator is far away from the propellant, and the propellant is sealed in the propellant shell, so even if the needle detonator accidentally ignites, it is impossible to ignite the propellant, which can be used for propellant time fuze or self-destructing powder disc launch Time to ignite. The invention has the characteristics of good safety, compact size, simple structure and low price.

Description

technical field [0001] The invention relates to the technical field of fuze ignition, in particular to an in-bore ignition mechanism of a fuze adopting the principle of a detonator and a space flameproof. Background technique [0002] The ignition mechanism in the fuze chamber is a typical firing mechanism. Since the working environment it utilizes is a launch environment, which is relatively stable, its function is relatively reliable. It has been widely used in various gunpowder principle fuzes, such as gunpowder time fuze, gunpowder delayed release insurance fuze and gunpowder self-destruct fuze. However, in the traditional firing mechanism in the fuze chamber, whether the firing pin is fixed and the firing cap recoils or the cap is fixed and the firing pin recoils, the accidental firing of the cap will ignite the subsequent agent along the established fire transmission path, causing the fuze to accidentally ignite. It will ignite and explode (or make the fuze invalid),...
