Four columns 10, a base 13, four corner connectors 1 are centered on the base 13, symmetrically distributed above the base 13, and two long-side handrails 2 are connected by handrail connectors 7 to form a frame. The long side is installed between the adjacent top corner connectors 1, and the two short side handrails 3 are connected by the handrail connector 7 to form a short side of the frame, and the short side and the long side are connected to each other when the frame is fully expanded Vertical, parallel to each other when the frame is completely folded, and connected by the top corner connector 1, similarly assemble the other two long-side handrails 2 and short-side handrails 3 through the top corner connector 1 and the handrail connector 7 to form a For the rectangular frame shown in Fig. 1, when the above-mentioned armrest and the corner connector 1 are installed, the way of flexible connection is selected, and the hinged connection is mostly used, so that the armrest can rotate around the corner connector 1. Four uprights 10 are respectively fixedly connected under the four corner connectors 1, as shown in Fig. The upper end of the slide bar 9 is fixedly connected with the lower part of the corner connector 1, and the lower end is fixed on the foot seat 15 and is connected with the bottom frame retractable rod 11 through the retractable connector 16. The frame structure in this embodiment uses the slide rod 9 And lifting slide block 8 replaces the traction rope and the gear that transmission frame adopts, and its structural stability is stronger, and also safer, also reduces production cost simultaneously, and saves the traction rope threading into standpipe during installation, in Pipe end positioning and other steps, thereby improving the production efficiency of the frame;

Wherein, there is a rectangular groove at the connection between the bottom frame retractable rod-11 and the retractable connector 16, which is used to place the retractable connector 16. The retractable connector 16 is connected with the slide bar 9 and the bottom frame retractable rod-11. Both are hingedly connected, and the other end of the bottom frame retractable rod-11 is hingedly connected with the base 13. At the end where each slide bar 9 connects with the corner connector 1, there is a lifting slider 8 matched with the slide bar 9. The lifting slider 8 is sleeved on the slide bar 9 and can move up and down along the slide bar 9. . Lifting connectors are arranged between the lifting slider 8 and the short-side handrail 3 and the long-side handrail 2 .

The following is an introduction to the frame retraction operation method in this embodiment:

The method of receiving the frame is as follows:

Pull up the base 13 upwards, since the base frame retractable rod-11, the slide bar 9 and the base 13 are hinged, the base frame retractable rod-11 will be driven to move upward during the upward movement of the base 13;
