Description
Technical field
The present invention relates to the locking device and its application method of a kind of expandable type truss structure, and in particular to one kind works as purlin
When frame is deployed into designated state, can effectively latch-up structure.
Background technology
Deployable trusses structure is a kind of new type foldable structural system for growing up in recent years, in Aero-Space, mechanic
Have in journey and daily life and widely apply.The concept of deployable structure is familiar with already for people, such as daily life
Umbrella in work struts storage, and the expansion of folding seat uses the structure type of open-close type with folding and perhaps great stadiums
Etc., with the development of aerospace industry, deployable structure is due to the distinguishing feature with foldable expansion and wide application neck
Domain, increasingly receives the attention of various countries scientific worker, achieves huge development.
For deployable trusses, how to realize that locking function is a considerable problem, for this problem, both at home and abroad
Scholar expand substantial amounts of research.At present, the locking device applied on most of deployable trusses, main thought is in locked dress
Put installation and have the resilient and different open-cell material in two ends aperture, during expansion, as the Suo Dingqiu on steel wire rope
When passing through aperture, because upstream end aperture is big and material has elasticity, can be very good to squeeze through, but want when ball is locked
When returning in situ because return terminal aperture is smaller, lead to not it is return, so as to realize locking function.But this locking device,
Although locking function can be realized well, locking state cannot be released, so that for the later stage reclaims deployable trusses or folding
Folded deployable trusses increased difficulty.
For deployable trusses, realize that locked is essential with folded state conversion.
