Embodiment Construction

[0011] according to figure 1 , figure 2 , image 3 and Figure 4 , the portable bed includes a waist ring 1, a foot bar 2, a side bar 3, a flat connecting plug 4, a cylindrical connecting plug 5, a circlip 6, a foot cover 7, a flat cover 8 and a nylon cloth bed surface 9 ;

[0012] The waist ring 1 is a circular piece made of nylon injection molding. There are four arc-shaped depressions on the inner side of the waist ring 1. Each of the four arc-shaped depressions of the waist ring 1 has a circular perforation. The four circular perforations of the circle 1 circle are distributed into quarters, the arc-shaped depression of the waist ring 1 is located above the circular perforation to form a V shape, and the arc-shaped depression of the waist ring 1 is located below the circular perforation to form an inverted V shape, the arc-shaped concave V-shape and inverted V-shape of the waist ring correspond to the wavy bends when the legs are stretched and folded.

Abstract

A portable bed comprises a middle ring, four bottom rods, four side rods, two flat connecting plugs, four cylindrical connecting plugs, four -shaped circlips, four bottom covers, four flat blank caps and two nylon fabric bed parts. The side of the middle ring is provided with four circular through holes. The bottom rods are made by stamping and bending metal round tubes. The middle corrugated outer side of each bottom rod is provided with a circular hole riveted to the corresponding circular through hole of the middle ring. Each bottom rod is provided with a transverse slot in which the corresponding -shaped circlip is connected. Two of the flat connecting plugs are plugged into the rear ends of front two of the side rods by riveting. The flat blank caps cover the front ends of two front side rods and the rear ends of two rear side rods. The four front side rods are entered into bags on two sides of the two nylon fabric bed parts, respectively. Each cylindrical connecting plug comprises a rivet nut and a nylon tubular member. The four rivet nuts are riveted to the middle bottom faces of the four side rods, respectively. The four nylon tubular members are screwed to the four rivet nuts through four bolts, two front side rods are connecting with two rear side rods, and the nylon tubular members on the four side rods are entered into tube holes in the tops of the four bottom rods and are positioned with the four -shaped circlips.
