Abstract

The invention discloses a non-firework fusing type two-way connection and separation device, the upper end of a fusing release device is provided with a fusing release device base and a separation system front end, a connecting screw rod is connected to the upper end of the fusing release device, the lower end of the fusing release device is connected with the upper end of an ejector rod sliding block, and a sleeve is fixed with the fusing release device base; the lower end of the sleeve is fixed to the bottom cover, the sleeve is provided with a steel ball mounting hole in the radial direction, the ejector rod sliding block is mounted in the sleeve, the middle cylindrical face of the ejector rod sliding block is in sliding fit with the inner wall of the sleeve, and the outer wall of the middle cylindrical face of the ejector rod sliding block is provided with a steel ball locking groove in the circumferential direction. The lower part of the ejector rod sliding block is provided with a small spring supporting rod. A small spring is installed between the bottom cover and the ejector rod sliding block in a pressing mode, a shell is fixed to the rear end of the separation system, a sleeve is installed in the shell and is in sliding fit with the outer wall of the sleeve, a steel ball locking groove is formed in the inner cylindrical face of the shell in the circumferential direction, and a large spring is installed between the inner end face of the shell and the bottom cover in a pressing mode. The non-firework fusing type two-way connection and separation device is low in unlocking impact, high in safety, small in size and capable of being repeatedly used.

Description

technical field [0001] The invention relates to the technical field of aerospace separation systems, in particular to a non-pyrotechnic fuse type two-way connection and separation device. Background technique [0002] Connection and separation technology has always been widely concerned as a key technology in the field of aerospace separation system technology. At present, pyrotechnic connection and separation devices are widely used, but when the pyrotechnic device is unlocked and separated, the explosive force will generate a large impact force, which will cause damage to the surrounding area of ​​the device. Therefore, it is urgent to study the use of low-impact non-pyrotechnic connection and separation technology. With the vigorous development of my country's aerospace industry, there is a greater demand for low-impact connection and separation technology products. At present, the disadvantages of the non-pyrotechnic fusible unlocking technology are that the equipment i...
