Abstract
The utility model discloses a safe quick-clipping fastener for a scaffold, and is characterized in that the center line of a spline arranged at the end surface of an existing hyperbolic press cap runs through the axle center of the eccentric axis of a T-shaped eccentric tension rod, and two adjoining tooth roots have the same distance with the eccentric axis. The utility model has the advantages of a simple and reasonable structure, a simple manufacturing process and safe, reliable and quick locking and positioning, effectively increases the price-performance ratio of the scaffold parts, and is suitable for substituting the existing scaffold parts.
Description
The utility model relates to scaffold clasp for building, and refering in particular to is a kind of safety fast clamping scaffold fastening.
At present, the steel pipe scaffold fastening clip that building trade is generally used, generally be to adopt the screw and nut fastening structure, when installation, demolition, time-consuming, effort, labor strength is big, and the recycling rate of waterused of fastener is lower, cause increasing of cost of production, occurred a kind of fast clamping scaffold fastening that is made of pedestal and hyperbola gland and securing member recently, it utilizes the pointed crosspiece of the teeth groove of hyperbola gland end face setting and T type eccentric links end to mesh soon and realizes quick fastening locking.The fast clamping scaffold fastening of this structure, in use have simple to operate, fastening fireballing advantage, but because the problem that exists on its structure design, its sharp type crosspiece is fast, and to mesh effect bad with teeth groove, it is fastening unreliable to cause.
The purpose of this utility model is to overcome the deficiency of prior art and a kind of rational in infrastructure, safety fast clamping scaffold fastening that processing and manufacturing is easy, easy to install is provided.
The utility model is to adopt following proposal to realize: it is that the axle center and adjacent two tooth roots to the distance between the eccentric shaft that make the center line of the teeth groove of existing hyperbolical gland end face setting pass T type eccentric links eccentric shaft are equal difference.
Concrete structure of the present utility model describes in detail below in conjunction with accompanying drawing:
Accompanying drawing 1 is the utility model front view.
Accompanying drawing 2 is an eccentric shaft structure schematic diagram in the utility model.
Accompanying drawing 3 is the A-A sectional view of accompanying drawing 2.
See accompanying drawing 1,2,3, the utility model is by pedestal 1, hyperbola gland 2, T shape eccentric links 3, eccentric shaft 4 is formed, described hyperbola gland 2 one ends are hinged on an end of pedestal 1, other end upper surface is provided with teeth groove 6, T shape eccentric links 3 is articulated in the pointed crosspiece 5 that the other end of pedestal 1 and its end be provided with by eccentric shaft 4 and can be embedded in the teeth groove 6, and the center line of teeth groove 6 passes the axle center of eccentric shaft 4, and adjacent teeth is equal difference apart from the distance in eccentric shaft 4 axle center.
Using method of the present utility model and operating principle are sketched in following; During the utility model use, only need pedestal and hyperbola gland cover are buckled on the scaffolding steel pipe, then, in the pointed crosspiece 5 embedding teeth groove 6 with T type eccentric links end, rotation eccentric axis 4 can reach the purpose that locking is located; The utility model is owing to guaranteed that the center line of teeth groove 6 passes the axle center of eccentric shaft 4, therefore, can avoid pointed crosspiece because of T type eccentric links end to contact positioning phenomenon with the flank of tooth and take place, guarantee that pointed crosspiece inlay card goes into the teeth groove root, so that safe and reliable position and lock to be provided; Simultaneously, because the distance in adjacent teeth root distance eccentric shaft axle center is equal difference, therefore the scaffold tube that changes to some extent for diameter also can realize safe and reliable clamping location, has promoted its ratio of performance to price effectively.
In sum, the utility model is simple and reasonable, processing technology is simple, the locking positioning security is reliable, rapidly, the effective ratio of performance to price of hoisting scaffold parts, be suitable for as the renewal product that has the scaffold parts now.
