Description

A kind of band for truss is from the pleated sheet structure of lock function

Technical field

The present invention relates to a kind of band for truss from the pleated sheet structure of lock function.

Background technology

Truss is a kind of supporting traverse structure being formed by connecting by welding, riveted joint or bolt by rod member, truss rod member mainly bears axial tension or pressure, thus make full use of the intensity of material, save material when span is bigger than real web grider, alleviate deadweight and increase rigidity. Truss in the middle of all kinds of engineer applied process, truss-frame structure existed connect between node insecure, it is easy to produce the situation of viscous deformation in truss-frame structure, cause truss-frame structure unstable, implement for ease of engineering meanwhile, need truss to fold, it is convenient to transport and stores.

Summary of the invention

It is an object of the invention to provide a kind of band for truss from the pleated sheet structure of lock function, by band firm connection between node from the pleated sheet structure of lock function realizes between truss-frame structure node, and the folding of truss rod member can be realized, present configuration is simple, connect closely, securely, folding convenient and saving space, can be applicable to large-scale truss, and it is applied to folding and spells in the mobile performing device product such as stage, movable chorus platform.

For achieving the above object, the present invention is achieved by the following technical solutions: a kind of band for truss is from the pleated sheet structure of lock function, comprise folding head I, folding head II and from lock set, it is characterized in that, described is made up of bolt, card hook, nut and spring from lock set, described bolt is fixed by nut locking after folding head I, card hook and folding head II, and spring is between card hook and bolt. Described band, from the pleated sheet structure of lock function, is realized described card hook and described folding head I, the self-locking folding head II and unlocking function by the interaction of described card hook, bolt and spring.

One end I of described folding head I is hollow cylindrical configuration, and the other end II both sides are the fold latch ear I respectively having a tape punching I, and there is a hole clipping I on folding head I top; Folding head II is end III is hollow cylindrical configuration, and respectively there is the fold latch ear II of a tape punching II the other end IV both sides, and there is a hole clipping II on folding head II top;Fold latch ear I and fold latch ear II can be fitted together to mutually.

Described is made up of bolt, card hook, nut and spring from lock set, and card hook is the hollow structure that centre has perforation III, has clamp I and clamp II outside the perforation III of card hook, has projection with clamp I and clamp II with inner side on one side.

Described fold latch ear I and fold latch ear II is fitted together to mutually, when truss is expansion state, the superimposed alignment of end IV of the end II and folding head II of folding head I, bolt is by nut locking after perforation I, perforation III and perforation II, and projection is buckled in spring one end, spring is between projection and bolt, clamp I card enters hole clipping I, and clamp II card enters hole clipping II, and clamp II protrudes outside hole clipping II, folding head I and folding head II linearly self-locking state, thus ensure that the firm of truss deployed configuration; When pinning clamp II, clamp I can leave hole clipping I, and folding head I or folding head II can rotate 180 degree in released state, and now truss is in folding rounding state, is convenient to transport and the storage of truss-frame structure.
