DEVICE FOR ATTACHMENT OF TWO PLATES Russian patent published in 2010 - IPC F16B5/10 F16B21/02 

FIELD: mechanics.

SUBSTANCE: device for attachment of two plates laid one on the other includes a long housing with bottom and upper part which includes the devices for keeping the second plate, and which is intended for crossing the hole in axial direction, which is provided in each plate, and equipped with locking devices brought into action during rotation, attachment devices of the bottom on the first plate by means of a clamp and compression devices which automatically bring the first and the second plates together during the locking process of assembly owing to rotation of long housing. Attachment devices using a clamp include an axial stop made together with long housing, and at least one support blade which is elastically deformed in transverse direction. Axial stop and support blade are made so that they can be supported with corresponding opposite surfaces of the first plate. Devices for retaining the second plate include at least one projection attached to upper part by means of elastically deformed connecting zone.

EFFECT: easy erection and reliability of keeping the plates.
