Lock buckle element for scaffold

Abstract

The invention discloses a lock buckle element for a scaffold in the technical field of the scaffold. The lock buckle element comprises a locking part arranged at a horizontal drawing pipe and a fixingpart arranged at an upright post, wherein the locking part comprises a rotating shaft rotationally penetrating through the end part of the horizontal drawing pipe; one end of the rotating shaft is fixedly connected with a second screw bolt; the periphery of the second screw bolt is fixedly connected with a rubber clamp element; the rubber clamp element is arranged into an elliptical cam; a firstlocking tooth is arranged in the position of each of two vertexes of the elliptical cam; the two groups of first locking teeth are in clockwise inclined arrangement; the fixing part comprises a U-shaped groove formed in the upright post; an installing block for being movably inserted and arranged in the U-shaped groove is arranged at one side of the upright post; a first ellipse is formed betweenthe installing block and the groove bottom of the U-shaped groove; the width size of the first ellipse is smaller than the length size of the elliptical cam; a second locking tooth is arranged at thegroove bottom of the U-shaped groove; a third locking tooth is arranged at one side, opposite to the groove bottom of the U-shaped groove, of the installing block; the second locking tooth and the third locking tooth are in anticlockwise inclination arrangement. Through the arrangement of the rubber clamp element, the dismounting is fast; the buckle locking is firm.

Description

technical field [0001] The invention relates to the technical field of scaffolding, in particular to a locking piece for scaffolding. Background technique [0002] Scaffolding refers to the various supports set up on the construction site for workers to operate and solve vertical and horizontal transportation. Scaffolding is generally used for temporary erection. It installs and fixes the columns and flat pipes with bolts, which is convenient for disassembly and installation. At the same time, it is convenient for transportation. However, during installation, tools are required to tighten the bolts. When disassembling, tools are still required Loose bolts are particularly inconvenient and time-consuming to use. Scaffolding is used for temporary erection at construction sites, which directly affects on-site construction. At the same time, for long-term use, bolts are tightened by nuts, which are easy to loosen, and the safety factor needs to be improved. Contents of the inv...
