Title:
DOVETAIL GROOVE INTERNAL LOCKING DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/100690
Kind Code:
A1
Abstract:
A dovetail groove internal locking device for external fixed positioning of a dovetail groove (4), comprising a first locking piece, a second locking piece pressing on the first locking piece, and a pin shaft (2) that penetrates and connects the first locking piece and the second locking piece, the pin shaft (2) fixing the first locking piece onto the dovetail groove (4). The present locking device is provided with a first locking piece, a second locking piece, and a pin shaft (2). The first locking piece touches and supports the dovetail groove (4). The pin shaft (2) exerts force on the first locking piece in the opposite direction from the direction in which the dovetail groove (4) exerts on the first locking piece. The second locking piece presses onto the inside of the first locking piece, thereby further increasing the force that the pin shaft (2) exerts on the first locking piece, and achieving the fixed positioning of the first locking piece and the dovetail groove (4). The present dovetail groove internal locking device has the following advantages: the stability of dismountable structures is enhanced, so such structures do not get deformed or fall apart easily during usage, and the invention is simple in structure, easy to use, and has strong locking force.
