Lid opening mechanism of throwing type launching tube

Abstract

The invention relates to a lid opening mechanism of a throwing type launching tube. The lid opening mechanism comprises a front lid, a tube opening ring, a launching tube body, a rotating shaft, a sealing flat gasket, a base, an explosive bolt, a mounting seat, a bottom plate, an O-shaped sealing ring, etc., wherein the lower end of the front lid is hinged with the rotating shaft through a U-shaped open slot, the upper end of the front lid is fixed on the explosive bolt through threads, and an annular sealing gasket slot is formed in the end surface of the front lid; the inner molded surface of the tube opening ring is in sleeve joint with the outer molded surface of the front end of the launching tube; the explosive bolt is mounted in the mounting seat, and the mounting seat is mounted on the bottom plate; and the base is mounted below the tube opening ring, and the rotating shaft is mounted in a through hole in the front end of the base. The lid opening mechanism adopts the technical scheme of single explosive bolt-open hinge, the pollution-free explosive bolt is selected as a lid throwing power source, the lid opening mechanism has the advantages of small unlocking impact, no pollution, simple structure and the like, the technical problems of unstable performance, complex mechanism, too large size and pollution of the lid opening mechanism in the prior art are effectively solved, and the lid opening mechanism is applicable to mass production of weapon systems.

Description

technical field [0001] The invention belongs to the technical field of missile launch, and in particular relates to a cover opening mechanism for a throwing launcher, especially suitable for small-diameter tactical missile launchers with high requirements on weight and volume. Background technique [0002] The barrel cover mechanism is an important part of the missile launch tube, which is divided into a front cover and a rear cover. In the storage and transportation state, the lid is closed and the launch cylinder forms a sealed container, which can not only provide a good storage and transportation environment for the missile, make the missile less susceptible to external damage, but also prevent the inert protective gas in the launch cylinder from leaking out. When the missile is launched, the cylinder cover can be quickly opened to avoid the passage of the missile flight and the gas flow. At present, the rear cover is mostly opened by the engine gas jet, while the front...
