FIXING DEVICE AND FIXING METHOD, WHICH PROVIDE RELEASE OF RETAINED LINK AT SPECIFIED MAXIMUM FORCE VALUE

摘要

FIELD: mechanics. ^ SUBSTANCE: fixing device includes retaining link connected to the post and having the possibility of acting on retained link. Retaining link has threaded part to be screwed in the post; there is a protrusion on the end of retaining link. Contact area of retaining link with retained link is located on the protrusion of retaining link. Relative deformations of protrusion of retaining link are within the yield area of retaining link material. Fixing method with possibility of automatic release of retained link in which by means of retaining link connected to the post provides the action on retained link. Retaining link is rigidly connected to the post so that such value of action of retaining link on retained link is provided that relative deformations of retaining link are within yield area of retaining link material. ^ EFFECT: reliable automatic release of retained link at specified force value. ^ 9 cl, 2 dwg
