Rapidly assembled/disassembled fastener

Abstract

The invention relates to a fastener for fixing scaffolds and an assembling / disassembling tool. A rapidly assembled / disassembled fastener is composed of an upper-half fastener and a lower-half fastener, the upper-half fastener is in damped hinge with the lower-half fastener by rivets, and the structures of the upper-half fastener and the lower-half fastener are the same; the upper-half fastener comprises a base, a cover plate, a draw bar, a lock lever and a safety lock; the left end of the base is hinged with the left end of the cover plate, and the right end of the cover plate is provided with a U-shaped open slot; a safety-lock clamp, a washer of the safety lock and a locking bit are fixed on the upper surface of the cover plate; the washer of the safety lock is hinged with the safety lock by a pin shaft and a torsional spring; when moving anticlockwise, the safety lock can be hung by the safety-lock clamp, thereby facilitating the operation of the lock lever; the right end of the base is hinged with the lower end of the draw bar, the upper end of the draw bar is eccentrically hinged with an arc head at the lower end of the lock lever, the draw bar is embedded in the U-shaped open slot of the cover plate, and the arc head at the lower end of the lock lever is pressed on the upper right end of the cover plate; and the locking bit is provided with a stepped locked groove, and the opening of the locked groove is shielded by the safety lock. The assembling and disassembling of the fastener are time-saving and labor-saving without fearing of being exposed to the sun and rain.

Description

technical field [0001] The invention relates to a fastener for fixing a scaffold. Background technique [0002] At present, the scaffolding fasteners used in the construction industry are fixed with bolts and nuts, which are time-consuming and laborious to install and disassemble, affecting the construction period. In addition, the fasteners are exposed to the sun and rain, which is easy to rust, which brings more trouble to disassembly and assembly. SUMMARY OF THE INVENTION [0003] In order to overcome the shortcomings of the prior art, the present invention provides a fast assembling and disassembling fastener, which saves time and labor for installation and disassembly, and is not afraid of the sun and rain. [0004] The technical solution adopted by the present invention to solve the technical problem is as follows: a quick-loading and dismounting fastener is composed of upper and lower half-fasteners, the upper and lower half-fasteners are connected with damping hin...
