Problems solved by technology

This support mechanism has the following disadvantages: 1. The telescopic tube includes at least two pipe fittings. Even if there are two pipe fittings, the material used is large and the cost is high; 2. When the folding bed frame is in the unfolded state, the telescopic pipe is in the minimum length state When in the folded state, the telescopic tube is in the maximum length state, which is limited by the requ

Embodiment 1

[0037] Please refer to Figure 1 to Figure 5 , the collapsible support mechanism includes a pivotal frame, and the pivotal frame includes two connecting rods 10 and a support rod 20 . The middle parts of the two connecting rods 10 are pivotally connected together. The pivotal connection is realized by riveting the middle parts of the two connecting rods 10 with rivets, for example, or connecting the two connecting rods 10 with a pivot seat. The middle part in this embodiment refers to the non-connecting rod ends. , including the midpoint but not limited to the midpoint, the illustration is based on the midpoint as an example; but it is not limited to this, according to needs, the following structure can also be adopted, the ends of the two connecting rods are pivotally connected together, or, The end of one connecting rod is pivotally connected with the middle part of the other connecting rod. The two connecting rods 10 are all slidably connected with sliding seats 11, and th...

Embodiment 2

[0043] Please check Figure 6 , It differs from Embodiment 1 in that: the connecting rod 10 is provided with a protruding portion 13 , and the sliding seat 11 can slide between the connecting seat 12 and the protruding portion 13 along the connecting rod 10 . The protruding portion 13 is realized by, for example, a bump protruding from the outside of the connecting rod or a solid seat fixed on the outside of the connecting rod. As shown in the figure, one or two bumps are used, and when in the folded state, the two sliding seats are in contact with the bumps.

Embodiment 3

[0045] Please check Figure 7 to Figure 10 , the foldable bed frame includes a plurality of foldable bracket mechanisms, the structure of which is as described in the first embodiment. The ends of the connecting rods 10 of every two adjacent support mechanisms are connected together by being pivotally connected to the connecting seat 13 . The plurality of support mechanisms are divided into a first support mechanism and a second support mechanism. The plurality of first support mechanisms are connected into three rows of series pivoted support groups 40 spaced left and right, and each adjacent two rows of support groups 40 The second bracket mechanism is pivotally connected. The upper connecting seat 13 also has the function of connecting the bedcloth or air blowing mattress, and the lower connecting seat 13 also has the function of a base stably supported on the ground.

Abstract

The invention discloses a folding support mechanism, a folding bed stand and a folding seat bracket. The folding support mechanism comprises a pin joint rack which includes two connecting rods in pin joint; the folding support mechanism further comprises a support bar; the two connecting rods are slidably connected with a sliding seat respectively, two ends of the support bar are rotatably connected with the sliding seats of the two connecting rods respectively, and maximum rotation unfolding angles of the support bar relative to the two connecting rods are no more than 90 DEG. According to the invention, since the maximum rotation unfolding angles of the support bar relative to the two connecting rods are no more than 90 DEG, the support bar is rotary relative to the two sliding seats; thus, the phenomenon of deadlocking is avoided, it is guaranteed that the support bar moves to a position where the support bar abuts against the two connecting rods so as to maintain unfolding, and the following beneficial effects are obtained: a) unfolding can be maintained by only using one support bar, so the advantages of saving of materials, low cost and light weight are obtained; b) demands for unfolding and folding can be satisfied at the same time; c) unfolding and folding are convenient and smooth, and the folding support mechanism has a long service life; and d) strength of the connecting rods are not influenced.

Description

technical field [0001] The invention relates to a foldable bracket mechanism, a foldable bed frame and a foldable chair frame. Background technique [0002] The foldable support mechanism is widely used in leisure products such as folding bed frames and folding chair frames. For example, the folding bed frame introduced in US Pat. It includes a pivot frame, the pivot frame includes two connecting rods, the middle parts of the two connecting rods are pivotally connected together, and the ends of the connecting rods of every two adjacent support mechanisms are connected together by being pivotally connected to the connecting seat. In order to increase the support strength, a telescoping tube that can expand and contract is also connected between the upper and lower connecting seats in the bracket mechanism. This support mechanism has the following disadvantages: 1. The telescopic tube includes at least two pipe fittings. Even if there are two pipe fittings, the material used ...
