Detailed ways

As shown in FIG. 1 , a foldable bed frame disclosed by the utility model includes two long poles 1 , and several "X" shaped cross support frames 2 are supported under the two long poles 1 . in:

Each long strut 1 is connected by two connecting rods 11, and the inner ends of the two connecting rods 11 are pivotally connected to the same connecting piece 3, thereby connecting the two together; the connecting piece 3 is formed by two triangular pieces 31 The inner ends of the two connecting rods 11 are pivotally connected to the two corners between the two triangular pieces 31, and one corner of the other two triangular pieces 31 is pivotally connected to a group of cross support frames 2 located in the middle of the bed frame. Both ends of the long pole 1 are pivotally connected to a set of cross support frames 2' through "L"-shaped locking pieces 4.

The support frame 2 in the middle of the bed frame is composed of two short rods 21, 22 and a long rod 23, and is connected by a "Z"-shaped pivot joint 24, wherein the upper end of a short rod 21 is pivotally connected to a long rod On the connector 3 of the rod 1, the other end is fixed at one foot of the pivotal member 24; at the other foot of the pivotal member 24, one end of the short rod 22 is fixed, and the other end of the short rod 22 is a free end; two short rods 21 , 22 are formed in a straight line direction; the upper end of the long rod 23 is pivotally connected to the connector 3 of the other long pole 1, and the middle part is pivotally connected between the two feet of the pivotal member 24, so that the support frame 2 is unfolded When forming an "X" shape, the two short rods 21, 22 form a stable support for the long rod 23 through the pivot joint 24.

The support frames 2' at both ends of the bed frame are also composed of two short rods 21', 22' and a long rod 23', and are connected by a "Z"-shaped pivot joint 24', and one of the short rods 21' The upper end is pivotally connected to the locking piece 4 of a long pole 1', and the other end is fixed to one foot of the pivoting piece 24'; the other foot of the pivoting piece 24' is fixed to one end of the short rod 22', and the short The other end of the bar 22' is a free end; two short bars 21', 22' are formed in a straight line; On the locking piece 4 of the other long pole 1, the middle part is pivotally connected between the two feet of the pivoting piece 24', so that the support frame 2' forms an "X" shape when unfolded, and the two short poles 21', 22' forms a stable support for the long rod 23' through the pivot joint 24', and at the same time, one end of the reinforcement sheet 5 is pivotally connected to the upper end of the outer casing rod 232', and the other end of the reinforcement sheet 5 is pivotally connected to another long rod 1 outside.

As shown in Figures 2 to 5, when the utility model is folded, firstly the two long poles 1 are concentrated together, and at the same time the rods of the support frame 2, 2' are also closed together (see Figure 2); secondly The support frame 2' located at both ends of the bed frame is close to the bottom of the long support rod 1 from the lower part of the long support rod 1. At the same time, the reinforcement sheet 5 pushes the outer sleeve rod 232' to expand relative to the inner sleeve rod 231' to meet the requirements of the support frame 2. 'Fold and close relative to the long pole 1 (see Figures 3 and 4); finally, the connecting rods 11 on both sides of the long pole 1 take the support frame 2' and rotate downward around the connecting piece 3 to clamp on the The two sides of the central cross support frame 2 (as shown in FIG. 5 ) complete the folding process. When the folding bed is unfolded, the unfolding function can be realized only by reversing the above actions.

To sum up, since the foldable bed frame of the present utility model has the "X"-shaped cross support frame 2' at both ends of the bed frame respectively provided with a reinforcement piece 5 pivotally connected with the long pole 1, the bed frame has an auxiliary support when it is unfolded. function to improve the firmness of the bed frame; in addition, the "X"-shaped cross support frame 2' at both ends of the bed frame and the setting of the structure of the inner and outer rods 231' and 232' make the reinforcement piece 5 realize the expansion of the bed frame. and folding, so that the bed frame can be easily and conveniently folded and unfolded.
