Abstract
A circular hollow-hole spacer connection fastener comprises connectors and at least two fasteners. The two fasteners are arranged at two ends of the connectors, and each fastener is composed of two cylinders with circular through holes, wherein the two cylinders are arranged vertically. The edge of the lower cylinder is provided with a notch at the position distant from the connectors by 90 degrees in the circumferential direction. Small spacers can be connected to form a large spacer without limit by the aid of the connection fastener, and the connection fastener is simple in structure, firm and reliable.
Description
Technical field
The present invention relates to a kind of junction button, be specifically related to a kind of openwork hole pad junction button that is exclusively used in.
Background technique
A kind of circular openwork hole pad as shown in Figure 1, elementary cell is comprised of the circular openwork hole of the different sizes of upper and lower layers, elementary cell is connected by horizontal vertical lines connecting sheet again, because the size of this pad of restriction of conditions of manufacture is no more than 50cm, if obtain large-area pad, just need to such minipad be coupled together with junction button.
Summary of the invention
The object of the invention is the needs for above-mentioned connection pad, circular openwork hole pad junction button is provided.
The object of the invention is to realize by following technological means:
Comprise link, at least two fasteners, fastener is arranged on the two ends of link, and fastener is comprised of the cylinder with manhole of two upper and lower layers settings, and the edge week of lower floor's cylinder is upwards provided with breach in 90° position, distance join part interval.
Preferred scheme, link quantity is one, fastener quantity is two.。
Preferred scheme, link quantity is four, and fastener quantity is four, and link and fastener are quadrangular array, and link is positioned at tetragonal four positions, limit, and fastener is positioned at dot location.
Compared with prior art the present invention has following obvious advantage: utilize junction button minipad infinitely can be connected into large pad, and simple in structure, solid and reliable.
