Embodiment Construction

[0012] like figure 1 and figure 2 As shown, in this embodiment, two parallel dead bolts 3 are housed in the lock body 1 , and a roller 17 is arranged below each dead bolt 3 . Dead bolt 3 is built-in with a spring mechanism, and a spring mechanism has two extension springs 12,13, and an end of extension spring 12 links to each other with dead bolt 3 and rocking arm 4, and the other end links to each other with lock body. One end of extension spring 13 links to each other with dead bolt 3, and the other end links to each other with rocking arm 4 and lock body 1. Cam mechanism comprises cam shaft 6, roller 5, rocking arm 4, and rocking arm 4 is contained on the rocking arm shaft 16, and roller 5 is contained in rocking arm 4 lower ends and contacts with cam shaft 6. The gear on the camshaft 6 meshes with the gear 7 of the reduction mechanism, and is connected with the external motor through gears 8, 9, 10. The fork 2 is connected to the handle 14 through the shift fork 18. Th...

Abstract

The invention relates to a lock structure. In order to solve the problem of aerospace vehicle locks, the invention discloses a catch lock, which includes a lock body, a lock tongue and a spring mechanism, and is characterized in that an automatic unlocking mechanism is arranged in the lock body. The automatic unlocking mechanism includes a deceleration mechanism and a cam mechanism, which can automatically unlock and lock. One side of the lock body is also provided with a manual unlocking mechanism for backup. The invention has the advantages of simple and compact structure, stable and reliable operation, and can realize the capture between two aerospace vehicles and keep the connection and separation of the two aircrafts.

Description

technical field [0001] The invention relates to the structure of a lock, in particular to a lock used on an aerospace vehicle. technical background [0002] There are many kinds of locks, and there are various locks with different structures according to different purposes. The basic structure of a known lock is composed of a dead bolt, a lock body, and a spring mechanism, which can realize the locking function. However, the existing locks that people are usually familiar with generally cannot be automatically unlocked, nor can they withstand a load of several thousand Newtons after being locked. Moreover, the requirements for the environment are not high, and it cannot work stably at a temperature of ±50°C in a vacuum state. Contents of the invention [0003] Aiming at the deficiencies in the prior art, in order to solve the locks used in aerospace vehicles, the invention provides a capture lock, which can be automatically unlocked and can bear a relatively large load. ...
