Separating bolt based on multi-stage steel ball transmission

Abstract

A separation bolt based on multi-stage steel ball transmission comprises a connecting screw rod which comprises an outer sleeve and an inner sleeve, and an ignition socket is installed on the connecting screw rod; a first limiting steel ball and a second limiting steel ball are arranged on the limiting piston; and the separating nut is clamped on the connecting screw rod through a second limiting steel ball. The ignition powder is arranged in the connecting screw rod of the double-layer sleeve structure, noise generated by explosion of the ignition powder can be effectively reduced, the ignition powder is arranged in the inner sleeve of the connecting screw rod, the ignition powder can be prevented from being affected with damp, and it is guaranteed that the ignition powder is smoothly ignited. In addition, the device is simple and reasonable in structural design, has very stable controllability, and ensures that the connecting screw rod can be thoroughly separated from the separation nut under the condition that the ignition powder is ignited. Compared with the prior art, the separation bolt based on multi-stage steel ball transmission is an underwater release mechanism with high use reliability.

Description

Technical field [0001] The present invention belongs to the field of releasing the structure technology of aviation goods. More specifically, it involves a separate bolt based on multi -stage steel ball transmission. Background technique [0002] With the continuous deepening of ocean development, more and more unmanned submarines are applied to the field of underwater products. [0003] The use of underwater aircraft for equipment can greatly improve the concealment of the product. After reaching the preset point, the underwater aircraft will give the mobility signal to the delivery equipment. ThereforeIt is particularly important in this process. [0004] At present, the existing separation structures mostly use fireworks (explosive bolts, etc.), and rely on the weak area of the frying bolt to achieve separation.Low safety and other disadvantages.In addition, there is a method of removal release by electromagnetic magnets. Although this release method is less noisy, there is a ...

AI Technical Summary

Problems solved by technology

[0004]At present, most of the existing separation structures use pyrotechnics (explosive bolts, etc.), relying on explosives to break the weak area of ​​the bolts to achieve separation. The release method has disadvantages such as high noise, easy to be found, and low safety of transportation packaging operation.

In addition, there is also a method of releasing the pin by using an electromagnet. Although this release method is less noisy, it has the problem of poor reliability of the release of the pin, and when there is a lateral force on the pin, it is also prone to jamming. The hysteresis phenomenon causes the problem that the mechanism does not operate
