Description

A kind of rotary buckle that freely stretches

Technical field

The utility model relates to fastener type steel pipe scaffold and sets up the connection area, is specially a kind of novel rotary buckle that can freely stretch that connects scaffold.

Background technology

The fastener of setting up the various models of needs of fastener type steel pipe scaffold, in the setting up of scaffold, rotary buckle one of the connector that is absolutely necessary, it is mainly used in the connection that two steel pipes are arbitrarily angled intersection, especially uses more when (comprising vertical bracing and horizontal cross brace) in that bridging is set.In setting up the scaffold process, because not at grade as two steel pipes of bridging, centre distance between the steel pipe is 48mm, so be used to set up the steel pipe of scaffold and be used to be provided with between the steel pipe of bridging always leave the space, the steel pipe that is used to be provided with bridging always can not closely be connected preferably with the steel pipe of setting up scaffold.With rotary buckle fixedly the time, the steel pipe that existing rotary buckle can only guarantee to be used to be provided with bridging closely is connected with scaffold, an other steel pipe will be crooked so that with rotary buckle bridging and scaffold are fixed, but so will install for bridging brings very big difficulty maybe bridging can't be installed, bring very big inconvenience not only for the integral construction of scaffold, have a strong impact on the scaffold building progress, and obviously reduce the supporting capacity of bridging, make it not reach designing requirement.In work progress, many building operations personnel bring hidden danger for the general safety of scaffold because bridging is installed difficulty even abandoned installing bridging, even cause scaffold to cave in and cause accident, cause serious casualties and property loss.

Summary of the invention

In order to overcome the shortcomings and deficiencies that prior art exists, the purpose of this utility model is, a kind of novel rotary buckle that can freely stretch is provided, and this novel rotary buckle can freely stretch, and can regulate the rotary buckle spacing, accurately fixing steel pipe scaffold.

In order to realize above-mentioned technical assignment, the utility model adopts following technical scheme:

A kind of rotary buckle that freely stretches, comprise first rotary body and second rotary body that shape is identical, it is characterized in that, described first rotary body and the second rotary body symmetry are positioned at the linkage both sides, be connected with first anchor clamps on first rotary body, be connected with second anchor clamps on second rotary body, first rotary body and second rotary body fuse by linkage.

Other characteristics of the present utility model are:

Linkage comprises screw rod, and the screw rod two ends have first nut and second nut respectively, and first nut is connected with first rotary body, and second nut is connected with second rotary body.

The first above-mentioned anchor clamps by rivet in first rotary body, one side, the first anchor clamps opposite side also is connected with a T type bolt, first nut that matches with a T type bolt is arranged on the one T type bolt, when first anchor clamps rotate to a T type bolt position, first anchor clamps are locked by first nut.

The second above-mentioned anchor clamps equally by rivet in second rotary body, one side, the second anchor clamps opposite side also is connected with the 2nd T type bolt, second nut that matches with the 2nd T type bolt is arranged on the 2nd T type bolt, when second anchor clamps rotate to the 2nd T type bolt position, second anchor clamps are locked by second nut.

The cavity that above-mentioned first rotary body and first anchor clamps locking back are constituted is for circular, and the cavity that second rotary body (2) and second anchor clamps (21) locking back are constituted is similarly circular.
