[0025] Such as Figures 1 to 4As shown in the figure, a double-layer folding bed with a linkage folding ladder is provided, which is convenient for unfolding and folding, and can realize the linkage between the upper and lower beds of the double-layer folding bed, facilitating the unfolding or closing of the double-layer folding bed, and effectively improving the unfolding and closing efficiency of the double-layer folding bed. The double-layer folding bed of this embodiment includes a cabinet body 1, an upper frame body 2, and a lower frame body 3. The middle positions of the upper frame body 2 and the lower frame body 3 are horizontally rotatably connected to the inner wall of the cabinet body 1, so that the upper frame body 2 and the lower frame body 3 can be rotatably unfolded or closed and stored in the cabinet body 1. Among them, the linkage folding ladder of this embodiment includes a folding ladder main body 4 connected between the upper frame body 2 and the lower frame body 3 and located on the side edge outside the cabinet body 1. When the upper frame body 2 or the lower frame body 3 rotates, it can drive the folding ladder main body 4 to rotate to achieve unfolding or folding. At the same time, under the drive of the folding ladder main body 4, the lower frame body 3 or the lower frame body 3 is driven to be unfolded and closed in a linkage manner, making the unfolding or closing of the double-layer folding bed more convenient.
[0026] Specifically, as Figures 1 to 2 shown, the folding ladder main body 4 of this embodiment includes a first upright post 41, a second upright post 42, and a plurality of cross-bar pedals 43 vertically arranged at equal intervals between the first upright post 41 and the second upright post 42 from inside to outside. After the double-layer folding bed is unfolded, the first upright post 41, the second upright post 42, and the cross-bar pedals 43 can be combined to form the folding ladder main body 4 connecting the upper frame body 2 and the lower frame body 3. Among them, the two ends of the first upright post 41 and the second upright post 42 of this embodiment are respectively rotatably connected to the side edges of the upper frame body 2 and the lower frame body 3, and the two ends of a plurality of cross-bar pedals 43 are respectively rotatably connected to the first upright post 41 and the second upright post 42. When the upper frame body 2 or the lower frame body 3 rotates and unfolds in the cabinet body 1, the first upright post 41 and the second upright post 42 can be vertically connected to the side edges of the upper frame body 2 and the lower frame body 3 from inside to outside under the drive of the upper frame body 2 or the lower frame body 3. At the same time, the cross-bar pedals 43 are horizontally connected between the first upright post 41 and the second upright post 42 under the drive of the first upright post 41 and the second upright post 42 and are combined to form the folding ladder main body 4 connecting the upper frame body 2 and the lower frame body 3, thus realizing the unfolding of the folding ladder main body 4 without manual operation, and the operation method is convenient; when the upper frame body 2 or the lower frame body 3 rotates and folds into the cabinet body 1, the first upright post 41 and the second upright post 42 can also rotate and approach under the drive of the upper frame body 2 or the lower frame body 3. At the same time, the cross-bar pedals 43 are longitudinally connected between the first upright post 41 and the second upright post 42 under the drive of the first upright post and the second upright post, so that the first upright post 41, the second upright post 42, and the cross-bar pedals 43 are all vertical on the side edges of the upper frame body 2 and the lower frame body 3, realizing the folding of the folding ladder main body 4 without manual operation, and the operation method is convenient. At the same time, when the upper frame body 2 or the lower frame body 3 rotates to be unfolded or closed, the first upright post 41 and the second upright post 42 can drive the lower frame body 3 and the upper frame body 2 to rotate synchronously, realizing the synchronous unfolding or folding of the upper and lower beds of the double-layer folding bed, and improving the unfolding and closing efficiency of the double-layer folding bed.
[0027] Further, as shown in Figure 1 and Figure 2 In order to reduce the volume of the folding ladder main body 4 after folding and improve the folding effect of the folding ladder main body 4 in this embodiment, mounting grooves 44 are provided on the opposite surfaces of the first upright post 41 and the second upright post 42 along their respective lengths. The thickness of the crossbar pedal 43 is adapted to the structure of the mounting grooves 44, and both ends of the crossbar pedal are respectively inserted into the mounting grooves 44 of the first upright post 41 and the second upright post 42. When the folding ladder main body 4 is folded, the crossbar pedal 43 can be driven by the first upright post 41 and the second upright post 42 to be longitudinally arranged and fitted into the mounting grooves 44, thereby effectively reducing the volume of the folding ladder main body 4 after folding and facilitating the hiding of the double-layer folding bed after folding.
[0028] As shown in Figures 1 to 4 In this embodiment, first rotating shafts 45 that are horizontally inserted into the mounting grooves 44 are provided on both the first upright post 41 and the second upright post 42. Both ends of the crossbar pedal 43 are rotatably connected to the first rotating shafts 45 in the first upright post 41 and the second upright post 42 respectively, thereby realizing the rotation of the crossbar pedal 43.
[0029] At the same time, second rotating shafts 5 are provided on the side walls of both the upper frame body 2 and the lower frame body 3 in this embodiment. The positions where the first upright post 41 and the second upright post 42 are connected to the upper frame body 2 and the lower frame body 3 are fixed through the second rotating shafts 5. When the upper frame body 2 or the lower frame body 3 rotates to be unfolded or folded, the first upright post 41 and the second upright post 42 can be driven to rotate, thereby realizing the unfolding or folding of the folding ladder body.
[0030] As shown in Figures 1 to 2 One end of the second upright post 42 connected to the lower frame body 3 in this embodiment extends to the bottom of the lower frame body 3 to form a support portion 421 for the folding ladder main body 4 after unfolding. An adjusting screw 422 for adjusting the support height is provided at the bottom of the support portion 421. Different ground conditions can be adapted through the adjusting screw 422, further enhancing the stability of the folding ladder.
[0031] As shown in Figures 1 to 2 In order to facilitate the unfolding or folding of the folding ladder body and the double-layer folding bed, a handle 46 for manually unfolding or closing the folding ladder main body 4 is provided at the front end of the second upright post 42 in this embodiment. The user can pull the handle 46 to rotate the first upright post 41 and the second upright post 42, thereby driving the upper frame body 2 and the lower frame body 3 to rotate and unfold in the cabinet 1, thus realizing the unfolding of the folding ladder and the double-layer folding bed; conversely, the user can push the second upright post 42 and the first upright post 41 to approach each other through the handle 46, so that the upper frame body 2 and the lower frame body 3 rotate and fold in the cabinet 1 to realize the closing of the folding ladder main body 4 and the double-layer folding bed, and the operation is simple.
[0032] Furthermore, in this embodiment, a driving mechanism 6 is also provided inside the cabinet body 1 for driving the folding ladder main body 4 and the double-layer folding bed to automatically unfold or close. The driving mechanism 6 is connected to the upper frame body 2 and the lower frame body 3, and can push the upper frame body 2 and the lower frame body 3 to rotate, thereby driving the folding ladder main body 4 to unfold or close. Specifically, the driving mechanism 6 of this embodiment includes a longitudinally arranged driving electric rod 61 and a linkage rod 62 whose two ends are respectively rotatably connected between the upper frame body 2 and the lower frame body 3. One end of the driving electric rod 61 is rotatably connected to the inner wall of the cabinet body 1, and the other end of the driving electric rod 61 is rotatably connected to one end of the upper frame body 2 located inside the cabinet body 1. When the driving electric rod 61 is activated, its telescopic rod pushes one end of the upper frame body 2 located inside the cabinet body 1 downward, so that the upper frame body 2 rotates inside the cabinet body 1 and the end located outside the cabinet body 1 flips into the cabinet body 1, realizing the closing of the upper frame body 2. At this time, the downward movement of the end of the upper frame body 2 located inside the cabinet body 1 drives the linkage rod 62 to move downward, thereby driving the end of the lower frame body 3 located inside the cabinet body 1 to move downward, and further realizing the flipping of the end of the lower frame body 3 located outside the cabinet body 1 into the cabinet body 1, thus realizing the automatic closing of the double-layer folding bed. At the same time, when the sides of the upper frame body 2 and the lower frame body 3 located outside the cabinet body 1 flip into the cabinet body 1, they drive the first upright column 41 and the second upright column 42 to rotate and approach each other, and make the crossbar pedal 43 fit into the installation groove 44 to realize the folding of the folding ladder main body 4, and further realize the automatic folding of the folding ladder main body 4; conversely, when the driving electric rod 61 is activated to pull the end of the upper frame body 2 located inside the cabinet body 1 upward, the automatic unfolding of the double-layer folding bed and the folding ladder body can be realized.
[0033] As Figure 2 and Figure 4 shown, longitudinal auxiliary cylinders 7 are provided at positions corresponding to the upper frame body 2 and the lower frame body 3 on the inner side wall of the cabinet body 1 of this embodiment. One end of the auxiliary cylinder 7 is rotatably connected to the inner side wall of the cabinet body 1, and the other end is rotatably connected to the side wall of the upper frame body 2 or the lower frame body 3. The auxiliary cylinder 7 can provide additional supporting force for the unfolding and closing of the double-layer folding bed and the folding ladder main body 4, making the folding and unfolding process smoother and safer.
[0034] In summary, the working principle of this embodiment is as follows: In this embodiment, a folding ladder main body 4 composed of the first upright column 41, the second upright column 42 and the crossbar pedal 43 therebetween is provided, and the two ends of the first upright column 41 and the second upright column 42 are respectively rotatably connected to the upper frame body 2 and the lower frame body 3. When the double-layer folding bed unfolds or closes, the folding ladder main body 4 can be driven to unfold or close, without the need to operate the folding ladder separately, which is convenient and fast; and the upper frame body 2 and the lower frame body 3 can be linked to unfold and close, which can effectively improve the unfolding and folding efficiency of the double-layer folding bed.
[0035] The embodiments described above are only the preferred embodiments of the present utility model, and the protection scope of the present utility model cannot be limited thereby.
