Technical Field

The invention relates to the field of scaffold connecting buckles, in particular to a scaffold connecting buckle.

Background

Scaffolding refers to various supports erected on a construction site for workers to handle and solve vertical and horizontal transportation. The general term of the building industry refers to the places which cannot be directly constructed on the building site and are used for exterior wall, interior decoration or high floor height. The steel pipes are connected and bridged by the connecting buckles to form a three-dimensional frame structure, so that constructors can conveniently live up and down or a peripheral safety net enclosure, a high-altitude installation component and the like.

Present scaffold puts up connector link for example (application number 201821928849.5, a locking fastener), the upper portion one end of base sets up the stay mounting groove, and the upper portion other end of base sets up the screw rod mounting groove, and the one end and the stay mounting groove of stay rotate to be connected, and the screw rod rotates with the screw rod mounting groove to be connected, be corresponding to screw rod one end body coupling locking plate on the stay, be equipped with on the locking plate with screw rod matched with screw rod movable groove, the screw rod is arranged in the screw rod movable groove to the nut through threaded connection on the screw rod realizes the fastening of stay and base and is connected. Although the connecting mode of the connecting buckle can effectively realize the locking operation of workpieces of various specifications and models and has a wide application range, if the screw is stressed in the vertical axial direction in the using process, the screw can fall off from the screw movable groove possibly, and the fixing effect of the connecting buckle is influenced.

Disclosure of Invention

The invention aims to solve the problem that a screw rod of a connecting buckle is stressed in a vertical axial direction in the prior art, the screw rod possibly falls off from a screw rod movable groove, and the fixing effect of the connecting buckle is influenced, and the scaffold connecting buckle is provided.

The technical problem to be solved by the invention is realized by adopting the following technical scheme:

a scaffolding connector clip, comprising:

the two retaining rings are tangent to each other and connected through the connecting bolt to form a connecting buckle;

the retaining ring comprises a connecting seat and a rotating semi-ring, one side of the connecting seat is hinged to one side of the rotating semi-ring, the other side of the connecting seat is hinged to a fixing screw, the other side of the rotating semi-ring is provided with a bayonet, the fixing screw can rotate to the bayonet when rotating around a hinged joint, a positioning nut and a base plate are installed on the fixing screw, a pin is arranged on the base plate, a slot is formed in the bayonet, the base plate is extruded when the positioning nut rotates, and the pin on the base plate is inserted into the slot.

Furthermore, the pin is provided with a through hole, the side part of the bayonet is provided with a through hole, the through hole penetrates through the slot, and a positioning pin is arranged in the through hole and can penetrate through the through hole on the pin.

Furthermore, a hollow cavity is arranged on the base plate, a turntable is arranged in the hollow cavity, and the turntable is fixedly connected to the positioning nut.

Furthermore, the end of the fixing screw rod is provided with a limiting block.

Furthermore, an extrusion spring is arranged between the limiting block and the positioning nut and surrounds the fixing screw rod.

The invention has the beneficial effects that:

the fixing screw rod clamping device is simple in structure, the positioning nut on the fixing screw rod is rotated in the using process, the base plate is extruded towards one side of the bayonet by the positioning nut, the pin on the base plate is inserted into the slot of the bayonet in the extruding process to form positioning on the fixing screw rod, and when the fixing screw rod bears stress perpendicular to the axial direction, the base plate can effectively prevent the fixing screw rod from deviating and prevent the fixing screw rod from falling off from the bayonet.
