Problems solved by technology

[0003] The first type of folding bed, such as figure 1 As shown, it includes a bed surface module, two bed frames A and middle support legs B; the bed surface module includes two bed frame frames C, and the inner sides of the two bed frame frames C are rotatably connected to the middle support leg B; the bed frames A and The first connecting rod D1 and the second connecting rod D2 are connected between the bed frame C to form a four-bar linkage mechanism. The four-bar linkage mechanism can be changed to choose between the folded state and the supporting state. In the folded state, the bed frame A is folded On the back of the bed frame C, in the support state, the upper part of the bed frame A protrudes above the bed frame C to form a gear part. The bed frame C is supported on the first connecting rod D1, so there are the following deficiencies: First, The bed frame C, the two connecting rods and the bed frame A in the supporting state are still in the state of four connecting rods, and the supporting strength needs to be strengthened; secondly, the bed frame C is supported on the first connecting rod D1, and the first connecting rod D1 The supporting weight is supported by the pivot connected by the first connecting rod D1 and the bed frame A, and the strength needs to be strengthened; thirdly, the distance between the two bed frames A is far away, and the supporting strength needs to be strengthened
[0004] The second type of folding bed includes a bed surface module, support legs on both sides, a middle support leg and a locking mechanism; The supporting legs are rotatably connected to the bed frame and the locking mechanism connects the side supporting legs and the bed frame to keep in the locked state, so there are following deficiencies: one, a locking mechanism must be provided to keep in the locked state; , the gravity of the bed frame is supported by the side support legs and the pivot of the bed frame, and the strength needs to be strengthened

Embodiment 1

[0049] Please check Figure 1 to Figure 16 , the folding bed includes a bed surface module 1 , two first supporting legs 2 and a second supporting leg 3 . The bed surface module 1 includes two bed surface frames 11 , the inner sides of the two bed surface frames 11 are rotatably connected to the second support legs 3 , and the two bed surface frames 11 are respectively connected with a first support leg 2 . In this implementation, two bed top frames are provided, and the two bed top frames are connected by the second supporting legs. The bed top frames can also be bed boards as required.

[0050] The first connecting rod 41 and the second connecting rod 42 are connected between the bed frame 11 and the first support leg 2, and the two ends of the first connecting rod 41 are respectively hinged on the bed frame 11 and the first support leg 2, and the second Both ends of the connecting rod 42 are hinged to the bed frame 11 and the first support leg 2 respectively. The bed surf...

Embodiment 2

[0056] Please check Figure 17 to Figure 21 , it differs from Embodiment 1 in that: the bed surface frame 11 and the first support leg 2 are provided with a locking mechanism 6 that can lock the first support leg 2 in the supporting state or unlock the above-mentioned locking, so as to further improve safety performance. The locking mechanism 6 includes a card 61 that can be slid on the back of the bed frame 11, an elastic body 62 against the card 61, and a post 22 protruding from the first support leg 2. The card 61 is provided with a hook 611 and The hook 611 cooperates with the post 22 to control the locking or unlocking of the locking mechanism 6 by sliding the card 61 . Furthermore, the card 61 is provided with a guide surface 612, and the protrusion 22 can be pushed against the guide surface 612 to push the hook to slide through the movement of the supporting legs, so as to realize automatic locking, and press to overcome the elastic body to realize unlocking. In the s...

Embodiment 3

[0058] Please check Figure 22 and Figure 23 , it differs from the second embodiment in that: the second supporting leg 3 is slidably connected with a sliding sleeve 32, the second ends of the two poles 51 are pivotally connected to the sliding sleeve 32, and the second supporting leg 3 is provided with There is a limiting projection 33 for limiting the maximum sliding position of the sliding sleeve 32 upwards.

Abstract

The invention discloses a folding bed. The folding bed comprises a bed surface module and a first supporting leg, wherein a first connecting rod and a second connecting rod are connected between the bed surface module and the first supporting leg; the bed surface module, the first supporting leg, the first connecting rod and the second connecting rod form a four-bar mechanism; a folding state or asupporting state can be selected through the change of the four-bar mechanism; in the folding state, the first supporting leg is folded on the back surface of the bed surface module; and in the supporting state, the top end surface of the first supporting leg supports the bottom surface of the bed surface module, and the first connecting rod and the second connecting rod are matched with the bedsurface module and the first supporting leg to form a triangular supporting structure. The folding bed has the advantages of high supporting strength, high stability and long service life; self-locking can be realized under the action of gravity, and the self-locking is in an unfolding state, so that the folding bed is more stable after bearing; and the layout is reasonable, and the structure is compact after folding.

Description

technical field [0001] The invention relates to the technical field of household articles or camping articles, in particular to a folding bed. Background technique [0002] There are two main types of existing folding beds: [0003] The first type of folding bed, such as figure 1 As shown, it includes a bed surface module, two bed frames A and middle support legs B; the bed surface module includes two bed frame frames C, and the inner sides of the two bed frame frames C are rotatably connected to the middle support leg B; the bed frames A and The first connecting rod D1 and the second connecting rod D2 are connected between the bed frame C to form a four-bar linkage mechanism. The four-bar linkage mechanism can be changed to choose between the folded state and the supporting state. In the folded state, the bed frame A is folded On the back of the bed frame C, in the support state, the upper part of the bed frame A protrudes above the bed frame C to form a gear part. The be...
