Abstract
The invention relates to a steel pipe scaffold fastener. The technical scheme which is adopted by the invention for solving the technical problem lies in that the steel pipe scaffold fastener is a cross-shaped base integrally cast by malleable iron, a T-shaped tightening latch is loaded in a cast groove formed in the upper part of the cross-shaped base, a sleeve nut is screwed in the right end of the tightening latch, the right end of the sleeve nut and an eccentric wheel pressing rod are movably riveted together by using a rivet, a rolling edge is cast at the lower part of the cross-shaped base, the rolling edge and an opening slot formed in the lower part of a cover tile are movably riveted together by using a rivet, another opening slot is formed in the upper part of the cover tile, a circular arc matched with the eccentric wheel pressing rod is cast at the right end of the opening slot in the upper part of the cover tile, and an eccentric wheel and a pressing rod are cast into one body. When the steel pipe scaffold fastener is used, scaffold steel pipes are placed in the semi-circular arc part of the cross-shaped base, and then the cover tile is closed, the T-shaped tightening latch is screwed in the sleeve nut, the right end of the sleeve nut and the eccentric wheel pressing rod are movably riveted and clamped in the upper opening slot of the cover tile, the eccentric wheel is in the circular arc of the right end of the cover tile, and the eccentric wheel pressing rod is pressed to complete a fastening task. The eccentric wheel pressing rod is pried up when a steel pipe scaffold is disassembled, the cover tile and the cross-shaped base are separated from steel pipes, and the assembly and disassembly are quick and convenient.
Description
Technical field
The present invention relates to a kind of building service apparatus, especially steel tube scaffold clasp.
Background technology
At present, be the cramps for steel scaffold that the present inventor declares for 1996 with the novel close prior art of the present invention, namely the patent No. is the patent of 962277703.Although this patent has done larger improvement to traditional scaffold jig, set up inside and outside adapter sleeve, interior fastening sheathed armful of tooth, blank structure is processed in inner-outer sleeve joint portion, cover tile, pull bar have innovation, but due to complex structure, manufacture craft is more loaded down with trivial details, cost is relatively high, is unfavorable for that suitability for industrialized production is applied.
Summary of the invention
In order to overcome the deficiency of existing cramps for steel scaffold, the invention provides a kind of novel steel tube scaffold clasp.This steel tube scaffold clasp, structure is simple, can quick adjustment, the Novel scaffold fastener that fastening, fast assembling and disassembling convenient, bearing capacity is large, solid and reliable, cost of production is low.
The technical solution adopted for the present invention to solve the technical problems is: steel tube scaffold clasp, it has malleable iron cross-shaped base cast in block, top casts out loading T-shaped tightening latch in groove, tightening latch right-hand member is screwed into sleeve nut, together with sleeve nut right-hand member is movably riveted on eccentric wheel depression bar rivet, cross-shaped base bottom casts out the ears or side handles of a utensil, open slot is cast out with cover tile bottom, be movably riveted on together with rivet, cover tile top casts out open slot, open slot right-hand member casts out the circular arc coordinated with eccentric wheel depression bar, eccentric wheel and depression bar cast solid.
Patent of invention steel tube scaffold clasp, in use, scaffolding steel pipe is placed in cross-shaped base semi arch and buckles cover tile, T-shaped tightening latch is screwed into sleeve nut, the right-hand member of sleeve nut and the activity of eccentric wheel depression bar are riveted and are snapped in cover tile upper shed groove, eccentric wheel is in cover tile right-hand member circular arc, and the fastening task of pressure eccentric wheel depression bar completes.
Lever up eccentric wheel depression bar during steel pipe scaffold dismounting, cover tile and cross-shaped base and steel pipe depart from.
This steel tube scaffold clasp, structure is simple, can Quick fastening, fast assembling and disassembling is convenient, bearing capacity is large, solid and reliable, cost of production is low, solve that the old fastener of tradition is drenched with rain, collides, a flimsy difficult problem of getting rusty.
