Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

As shown in Figures 1 and 2, it is a portable movable frame for carrying heavy objects, including four loading plates 1, movable wheels 2, variable splints 3 and adjustable connecting brackets 4;

Wherein, the loading board 1 is distributed in rectangular apex angles, and the movable wheel 2 is installed at the center of the bottom of the loading board 1 through a 360-degree rotating shaft 5; A rotating sleeve 6 is installed on the column, and the variable splint 3 on the adjacent two sides of the apex is connected through the rotating sleeve 6;

The adjustable connection bracket 4 includes a telescopic sleeve 41, telescopic control clips 42 on both sides and connecting rods 43, and the connecting rods 43 on both sides are sleeved in the telescopic sleeve 41, and the telescopic control clips 42 at both ends of the telescopic sleeve 41 Realize the telescopic fixing of the connecting rod 43 and the telescopic sleeve 41; the middle part of the outer side of the variable splint 3 is affixed with the mounting plate 7, and the connecting rod 43 passing through the mounting plate 7 is threaded and fastened by the fastening nut 8.
