Problems solved by technology
[0003] The fasteners used for steel pipe scaffolding are more common in life. For the steel pipe connection of scaffolding in the same direction in construction, butt fasteners are used for connection and fixation. When performing locking and fixing connection work, the staff usually use a wrench to tighten the screws. , in this process, on the one hand, when the space at the steel pipe connection of the scaffold is limited, it is troublesome to use a wrench to tighten the screws, which affects the working hours and reduces the efficiency of installation work; With a very good locking mechanism, under long-term use, the screws will inevitably loosen, thereby reducing the connection strength between scaffold steel pipes, and may even cause dangerous situations. Therefore, the present invention proposes a fast The removable locking device is used to solve the above problems

Embodiment Construction
[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below. The embodiments of the present invention and all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0029] see figure see Figure 1 to Figure 10 , the present invention provides a technical solution: a fast disassembly and assembly locking device for scaffold fasteners. The present invention includes a fastener main body 1, a first arc-shaped splint 2, a second arc-shaped splint 3, connecting posts 7 and Fixed locking mechanism 18;
[0030] The main body of the fastener 1 is connected with a first arc-shaped splint 2 and a second arc-shaped splint 3 through a pin shaft connection. The first arc-shaped splint 2 is integrally formed with a first connecting plate 4, and the second arc-shaped splint 3 is integrated. Forming is provided with a second con...

The invention discloses a rapidly-disassembled-and-assembled locking device for scaffold fasteners. When butt joint fasteners are installed, connecting through holes and limiting clamping grooves areformed in a first connecting plate and a second connecting plate, limiting clamping strips are arranged on connecting inserting columns, then lantern rings are fixed to sleeve connecting inserting columns, finally, and a movable locking clamping block in a fixing and locking mechanism is clamped and locked with a locking clamping groove in the side edge of a sleeve, so that clamping between a first arc-shaped clamping plate and a second arc-shaped clamping plate is firmer and more stable; and through the transmission effect among a control knob, a first transmission block and a second transmission block which are arranged in the fixing and locking mechanism, the fasteners are locked, fixed, disassembled and assembled more quickly and conveniently, on the premise that the connection firmness is guaranteed, the disassembling and assembling efficiency is improved, and the working economic benefits are guaranteed.
Description
technical field [0001] The invention relates to the technical field of scaffold fastener devices, in particular to a fast disassembly and assembly locking device for scaffold fasteners. Background technique [0002] Fasteners generally refer to the intermediate connecting parts connecting two components. In construction projects, they are mostly used to fix steel pipe scaffolding with an outer diameter of Φ48mm. Fasteners are divided into right-angle fasteners (cross fasteners and directional fasteners), rotary fasteners (movable fasteners and universal fasteners), docking fasteners (one-word fasteners and direct fasteners), etc.; there are many types of fasteners, mainly including new fasteners, steel pipe scaffold fasteners, cast steel fasteners, T-shaped Construction fasteners, concrete sleeper fasteners, wooden sleeper fasteners, rail fasteners, Vossloh fasteners, malleable steel fasteners, scaffolding fasteners, railway fasteners, steel plate stamping fasteners, butt fa...
