Referring to fig. 1 and 2, a folding bed includes a bed frame having an unfolded state and a folded state, and a locking mechanism for locking the bed frame in the unfolded state, the bed frame includes a foldable upper enclosure frame and more than three vertical rods 2 supported at the bottom of the upper enclosure frame, all the vertical rods 2 extend in the up-down direction and are sequentially arranged in the circumferential direction, and a stay bar mechanism 3 for driving the two vertical rods 2 to relatively approach or separate from each other is arranged between any two adjacent vertical rods 2. In the unfolded state, the frame has a plurality of sides, each of which has two uprights 2, and a set of strut mechanisms 3 arranged between the two uprights 2.

The stay mechanism 3 includes two diagonal stays 31 which intersect each other and are rotatably connected at the intersection, the diagonal stays 31 extend obliquely in the up-down direction, one end portion of each diagonal stay 31 is rotatably connected to one of the uprights 2, and the other end portion of each diagonal stay 31 is provided on the other upright 2 so as to be relatively slidable in the up-down direction while being relatively rotatable. Specifically, the lower end of the diagonal member 31 is pivotally connected to the lower portion of one of the vertical rods 2, the upper end of the diagonal member 31 is pivotally connected to the sliding member 4, and the sliding member 4 is provided on the other vertical rod 2 so as to be capable of sliding in the vertical direction. In this embodiment, the vertical rod 2 includes a vertical rod body 20, an upper rod seat 21A fixed at the upper end of the vertical rod body 20, and a lower rod seat 22A fixed at the lower end of the vertical rod body 20, the lower end of the diagonal rod 31 is pivotally connected to the lower rod seat 22A, and the sliding member 4 is a sliding sleeve slidably sleeved on the vertical rod body 20 and located between the upper rod seat 21A and the lower rod seat 22A.

The lengths of the two diagonal braces 31 in each set of brace bar mechanisms 3 are the same, and/or the lengths of the diagonal braces 31 in two adjacent sets of brace bar mechanisms are different. In this embodiment, the lengths of the two diagonal braces 31 in each set of brace bar mechanisms 3 are the same, and the lengths of the diagonal braces 31 in the two adjacent sets of brace bar mechanisms are the same.

The upper enclosing frame comprises a plurality of enclosing rods 1 which are sequentially arranged along the circumferential direction, when the frame is in an unfolded state, all the enclosing rods 1 are sequentially connected along the circumferential direction and are enclosed to form a closed frame shape, in the embodiment, the upper enclosing frame comprises four enclosing rods 1 which are sequentially arranged along the circumferential direction, the four enclosing rods 1 are enclosed to form a quadrilateral frame, and the extending directions of two adjacent enclosing rods 1 are mutually vertical when the bedstead is in the unfolded state; correspondingly, there are four of the uprights 2 and four sets of the strut mechanisms 3 are correspondingly provided. In other embodiments, the number of the surrounding rods 1 can be three, and the three surrounding rods 1 surround to form a triangular frame; the number of the surrounding rods 1 can be five, and five surrounding rods 1 surround to form a pentagonal frame; the number of the surrounding rods 1 can also be six, seven, eight and the like.

Each enclosing rod 1 comprises a first rod 11 and a second rod 12 which are connected along the length direction, and the length of the second rod 12 is larger than that of the first rod 11. In this embodiment, the lengths of the two second rods 12 in the two adjacent surrounding rods 1 are the same, and the lengths of the two first rods 11 in the two adjacent surrounding rods 1 are also the same. In some other embodiments, the lengths of the two second rods 12 in two adjacent surrounding rods 1 may also be set differently, so that the total lengths of the two surrounding rods 1 are different, that is, the widths of two surrounding edges adjacent to the upper surrounding frame are different.

In each of the surrounding rods 1, one end of the first rod 11 is rotatably connected to one end of the second rod 12 about a first rotation center line a, which is perpendicular to the vertical rod 2 and extends in the horizontal direction, and the other end of the first rod 11 is fixed to the upper portion of the vertical rod 2. In any two adjacent enclosing rods 1, the end part of the first rod 11 of one enclosing rod 1, which is not rotatably connected with the second rod 12, is fixedly arranged on the upper part of the vertical rod 2, and the other enclosing rod 1 can be arranged on the upper part of the vertical rod 2 along the length extending direction of the other enclosing rod 1 in a relatively sliding manner. Specifically, the upper portion of each vertical rod 2 is provided with a through hole 211 penetrating along the horizontal direction, and one surrounding rod 1 of two adjacent surrounding rods 1 can be slidably arranged in the through hole 211 along the length extending direction thereof.

When the frame is in the unfolded state, the end of the second rod 12 is inserted into the through hole 211; when the bed frame is converted from the unfolded state to the folded state, referring to fig. 3 and 6, each upright rod 2 slides relatively along the length extending direction of the surrounding rod 1 through the through hole 211, the upright rods 2 gradually approach each other until the rod body of the second rod 12 completely extends to the outer side of the through hole 211, the rotating connection part between the first rod 11 and the second rod 12 extends to the outer side of the through hole 211, the interference of the upper rod seat 21A on the downward rotation of the second rod 12 around the first rotation center line a is eliminated, at this time, the second rod 12 rotates downward around the first rotation center line a, and the second rod 12 and the upright rods 2 are relatively folded in a fitting manner. The first rotation center line a extends along the horizontal direction perpendicular to the upright rod 2, so that the second rod 12 can be attached to and folded in the upright rod 2, and the arrangement that the length of the second rod 12 is greater than that of the first rod 11 is combined, so that the width of the folded bed frame in the circumferential direction is greatly reduced when the bed frame is unfolded, and the folded bed frame is convenient to store and transport.

The outer end of the second rod 12 is further fixedly provided with a limiting member 13, see fig. 7 and 8, and the limiting member 13 is used for enabling the upright rod 2 to be positioned on the inside of the limiting member 13 on the girt 1. Specifically, when the bedstead is in the unfolded state, the limiting part 13 is abutted against the through hole 211, the limiting part 13 is in a cylindrical shape with an outer diameter larger than the aperture of the through hole 211, and the limiting part 13 does not have the size condition of passing through the through hole 211, so that the surrounding rod 1 is prevented from slipping out of the through hole 211.

When the bedstead is in an unfolded state, referring to fig. 1 and 2, a first rod 11 and a second rod 12 of the same enclosing rod 1 extend along the same horizontal direction, all the enclosing rods 1 are sequentially connected along the circumferential direction and are enclosed to form a closed frame shape, the extending directions of two adjacent enclosing rods 1 are mutually vertical to provide a stable support for the bedstead, two adjacent upright rods 2 are respectively arranged at two end parts of the same enclosing rod 1 in the length direction, and the enclosed space of the upper enclosing frame and the upright rods 2 reaches the maximum; when the bedstead is changed from the unfolded state to the folded state, as shown in fig. 3 and fig. 6, the locking mechanism is unlocked to the bedstead, the upright bars 2 are pushed inwards, the sliding members 4 slide upwards along the length direction of the upright bar bodies 20, so that the supporting bars 31 and the upright bars 2 are gradually folded relatively, and synchronously, the upper bar bases 21A are relatively slidingly closed along the length direction of the enclosing bar 1, so that the four upright bars 2 are gradually relatively closed; when the frame is in the folded state, as shown in fig. 7 and 8, two adjacent vertical rods 2 are located on the same first rod 11, and the second rod 12 rotates downward around the first rotation center line a, so that the second rod 12 extends in the up-down direction and is folded outside the corresponding vertical rod 2, the width of the frame in the circumferential direction is significantly reduced when the frame is unfolded, the upper end of the sliding member 4 abuts against the lower end of the upper rod seat 21A, and the supporting rod 31 and the vertical rod 2 are folded relatively.

In conclusion, the folding bed of the utility model occupies small space after being folded, is convenient for storage and transportation, and has simpler folding operation.
