Abstract
The production method of safe quickly-clamping scaffold fastener is characterized by that it ensures that the central line of tooth groove set on one end of double-curve press cover is passed through the centre of eccentric shaft of T-shaped eccentric drawber, and the distances of adjacent two tooth roots to shape centre of the above-mentioned eccentric shaft are equidifferent. Said fastener is safe, reliable, and its production process is simple.
Description
The invention discloses a kind of production method of scaffold clasp for building, refering in particular to is a kind of production method 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 objective of the invention is to according to simple for a kind of processing technology, as effectively to guarantee the reliable position and lock of safety fast clamping scaffold fastening safety fast clamping scaffold fastening production method.
The present invention adopts following proposal to realize: it is to be equal difference in axle center and adjacent two tooth roots to the distance between the eccentric shaft that the center line that adds the teeth groove that guarantees the setting of hyperbolical gland end face man-hour passes T type eccentric links eccentric shaft.
Concrete process of the present invention describes in detail below in conjunction with embodiment:
Accompanying drawing is the front view of the embodiment of the invention.
See accompanying drawing, the production method of the present invention---a kind of safety fast clamping scaffold fastening is to guarantee that the center line 7 of the teeth groove 6 that is provided with on hyperbola gland 2 one ends passes the center of the eccentric shaft 4 of T shape eccentric links 3, and adjacent two tooth roots are equal difference apart from the distance in eccentric shaft 4 axle center.
Using method of the present invention and operating principle are sketched in following: the present invention is owing to guaranteed that the center line 7 of teeth groove 6 passes the axle center of eccentric shaft 4, therefore, can avoid contacting the positioning phenomenon generation with the flank of tooth because of the pointed crosspiece side of T type eccentric links end, 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.The embodiment of the invention only needs pedestal and hyperbola gland cover are buckled on the scaffolding steel pipe in use, and 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;
In sum, the production method processing technology of the present invention---a kind of safety fast clamping scaffold fastening is simple, can effectively guarantee the reliable position and lock of safety fast clamping scaffold fastening, the locking positioning security is reliable, rapidly, the effective ratio of performance to price of hoisting scaffold parts, be suitable for as having the new production technology of scaffold clasp now.
