Novel opening cover lock capable of being automatically closed

Abstract

The invention relates to a novel opening cover lock capable of being automatically closed. The novel opening cover lock comprises a base, a bolt, a fixed cap, a spring, a pin, an unlocking pin, top columns, self-locking nuts and a lock clamp. When the opening cover lock is in the state before locking, the bolt penetrates through the spring and is arranged in a bolt hole of the base through the fixed cap, the bolt slides and carries out limiting in the bolt hole of the base and is fixed with the spring through the pin, the top columns penetrate through an upper top column sliding cavity B in the base to drive an unlocking sliding component H to slide in the base, the unlocking pin is fixed with the bolt in a matched connection mode, and the spring is in the compressed state. When the opening cover lock is in the state after locking, the unlocking pin is separated from the bolt, and the bolt is popped out and is inserted into a hole of the lock clamp under the action of the spring. The opening cover lock capable of being automatically closed has the advantages of being high in automatic closing and locking reliability, high in three-dimensional bearing, small in impact, simple in structure, good in manufacturability, capable of testing various environments, suitable for being used by planar opening covers, arc-shaped opening covers, oval opening covers and opening covers in various shapes and the like.

Description

technical field [0001] The invention relates to a new type of automatic closing flap lock, in particular to a locking mechanism applied to the rocket body structure of an aerospace launch vehicle to automatically close the flap, specifically a locking mechanism that relies on the load generated during the automatic closing of the flap to realize The utility model relates to a small-sized large-load-bearing connection lock for locking and reliably connecting an opening cover, which belongs to the technical field of structures. Background technique [0002] Before the launch of the space launch vehicle, the launch tower needs to transmit control and measurement information with the rocket. There are multiple open operating hatches. The beam of the launch tower is automatically opened tens of seconds before the rocket is ignited to complete the information transmission cable. At this time, because the personnel have already evacuated from the safe area, the cover on the rocket ...

AI Technical Summary

Problems solved by technology

The problems with this structure are that the reliability of the automatic closing and locking of the cover is not high, the torsion of the torsion spring needs to be strictly controlled (the cover cannot be closed if the torque is too large or small), and the matching size between the bevel of the bolt and the lock card is strict, etc. Disadvantages. In reality, after the information cable is pulled out, the flaps often fall but cannot be locked. Due to the state of rotation and loitering, the launch procedure has already been executed and cannot be stopped. As a result, these flaps are not closed during the rocket flight, which is easy to cause multiple failures. Foreign matter enters the rocket body and affects the internal environment of the rocket
