Document Type and Number:
WIPO Patent Application WO/2005/083278
Kind Code:
A1
Abstract:
This invention relates to a loose-proof method and an associated device, which locks a fastened object through the actions of bolt or nut or the like. According to this invention, at least one stop wheel can be rotatably provided in a locating hole formed in at least one contacting face of the fastening device. When an action force for loosing said fastening device is applied on fit in one directüon, a torque will be created. Said torque will bring the stop wheel finto rotation and make a stop tooth of the stop wheel protrude beyond the contacting face and penetrate finto a surface closely opposed to said contacting face to prevent the fastening device from loosing. The device of this invention can be used repeatedly and is adapted for left-hand screw and right-hard screw, therefore this invention can be used widely and create a desirable loose-proof effect.
