[0055] The two corner positions at the left end of the upper outer frame of the rectangular frame 1 and the two corner positions at the right end of the upper outer frame of the rectangular frame 2 are covered with anti-collision corner pads 1G;

[0056] The right ends of the front and rear sides of the upper outer frame of the rectangular frame 1 and the left ends of the front and rear sides of the upper outer frame of the rectangular frame 2 are both covered with anti-collision foot pads 2N.

[0057] The utility model is a folding bed with good lying comfort. The use principle is as follows:

[0058] When the folding bed is folded and stored, the operator grasps the handle 6 on the rectangular frame 1 with one hand and the handle 6 on the rectangular frame 2 with the other hand, and flips the bed frame body I to a state where one side of the roller 5 is at the bottom and one side of the handle 6 is at the top; flips the support leg 13 to a folded state that fits the corresponding rectangular frame 1 or rectangular frame 2, and then drags the rectangular frame 1 and the rectangular frame 22 toward the middle until the two fit together, at this time, the free end of one support arm 4-2 on the support leg 24 abuts against the rectangular frame 1, and the free end of the other support arm 4-2 abuts against the rectangular frame 22; finally, insert the locking pin O into the corresponding plug hole 1-2 and the plug hole 2 H-1, so that the rectangular frame 1 and the rectangular frame 22 are locked and connected to each other (see attached Fig.10 ).

[0059] When the folding bed is unfolded for use, the locking pin O is pulled out from the corresponding plug hole 1-2 and the plug hole 2 H-1; the rectangular frame 1 and the rectangular frame 2 are unfolded to the same horizontal plane, and then the support legs 3 at the left and right ends of the bed frame body Ⅰ are opened; the operator grasps the handle 6 on the rectangular frame 1 with one hand and the handle 6 on the rectangular frame 2 with the other hand, and turns the bed frame body Ⅰ to a horizontal state with the mattress body Ⅱ located above. At this time, the support legs 3 at the left and right ends of the bed frame body Ⅰ are opened to form an "eight" shape distribution structure (see attached Figure 3 ).

[0060] The folding bed of the utility model has good lying comfort. By setting the length dimensions of the rectangular frame 1 and the rectangular frame 2 in the left-right direction to a ratio range of 6:4 to 5.5:4.5, when an adult user lies on the folding bed in a flattened state, the buttocks are completely located on the rectangular frame 1 with the longer left-right length dimension. The structural design conforms to the principle of ergonomics, thereby significantly improving the lying comfort when the folding bed is used. The overall structural design is simple, the preparation and implementation feasibility is high, and the practicability is strong.

[0061] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
