Slider-type safety isolation mechanism based on hot-melting safety mechanism

Abstract

The invention discloses a slider-type safety isolation mechanism based on a hot-melting safety mechanism. The slider-type safety isolation mechanism based on the hot-melting safety mechanism comprisesa body (1), a slider (2), a cover plate (8) and the hot-melting safety mechanism (6). The hot-melting safety mechanism (6) comprises a limiting rod (601) and a hot-melting expansion structure. A sidegroove (202) is formed in the big end face of the slider (2), and the head of a pin pusher (5) is pressed on a steel ball installed in the side groove (202). A second blind hole (204) is formed in the other side of the big end face of the slider (2). The head of the limiting rod (601) sequentially penetrates through the second blind hole (204) and a first step hole (105). Holes used for mountingan initiating explosive device are formed in the body (1), the slider (2) and the cover plate (8), and the hole in the body (1), the hole in the cover plate (8) and the hole in the slider (2) in a released state coincide in the vertical direction. The slider-type safety isolation mechanism based on the hot-melting safety mechanism has a good explosion-proof isolation effect and is compact in structure and high in safety.

Description

technical field [0001] The invention belongs to the technical field of safety isolating devices, and more particularly relates to a slider-type safety isolating mechanism based on a thermal fuse. Background technique [0002] Pyrotechnics is a general term for a one-time action device that is equipped with gunpowder or explosives and explodes or burns to ignite the gunpowder or explosives after being stimulated by the outside world. The pyrotechnics are usually designed with an isolation mechanism, and its function is to make the explosion sequence The sensitive pyrotechnic components in the device are usually isolated from the next-level pyrotechnic components to ensure that the sensitive pyrotechnic components will not detonate the next-level pyrotechnic components when they are accidentally activated, thereby ensuring the safety of personnel and equipment during duty processing. [0003] At present, there are pyrotechnics insurance institutions, rod-type explosion-proof i...

AI Technical Summary

Problems solved by technology

[0003] At present, there are pyrotechnics insurance institutions, rod-type explosion-proof institutions, isolated rotor explosion-proof institutions and slider-type explosion-proof institutions, but the existing two-stage insurance explosion-proof institutions are large in size, low in versatility, and complex in structure , low reliability

The above defects limit the use of the slider type isolation mechanism, which has a certain impact on the practicability of the slider type isolation mechanism
