Description

Technical Field

[0001] This utility model relates to the field of folding beds for camping cabins, and in particular to a self-locking mechanism for folding beds for camping cabins. Background Technology

[0002] Camping modular folding beds are specifically designed for camping, featuring a high-strength metal frame and durable, breathable fabric, offering strong load-bearing capacity. Most are two- or multi-fold structures for easy and quick unfolding and storage, and are compact in size. Some bed frames have storage space, and some are height-adjustable, suitable for various scenarios such as military, emergency rescue, and field training.

[0003] In camping cabin scenarios, folding beds are widely used due to their portability and space-saving features, but the issue of securing them after folding has consistently impacted the user experience. Currently, most folding beds on the market lack a dedicated self-locking mechanism after folding. Once folded, they are easily unfolded accidentally by external force, not only taking up extra space but also potentially posing a risk of injury to nearby people. Even those few products that do have a self-locking mechanism often use a single buckle or a simple pin design, resulting in a rudimentary structure. This type of self-locking method only provides preliminary restriction of the folded state; during transport bumps or when subjected to lateral forces, buckles are prone to detachment and pins to loosen, leading to poor self-locking stability and failing to meet the safety and reliability requirements of camping cabins for equipment storage.

[0004] Based on this, a self-locking mechanism for folding beds in camping cabins is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a self-locking mechanism for a camping cabin folding bed in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A self-locking mechanism for a camping cabin folding bed includes a connecting block. One end of the connecting block is rotatably connected to a second folding hinge. One side of the second folding hinge is rotatably connected to a first folding hinge. One side of the connecting block is connected to a mountain-shaped positioning buckle. One side of the mountain-shaped positioning buckle is connected to a mountain-shaped fixing buckle. A limiting member for limiting the position of the connecting block is provided below the mountain-shaped fixing buckle.

[0007] Preferably, one end of the connecting block is connected to a rotating shaft, which is rotatably connected to the second folding hinge.

[0008] Preferably, the folding hinge is fixedly connected to a column on one side of the folding bed, and the column and the folding bed are fixedly connected.

[0009] Preferably, the mountain-shaped fixing buckle is fixedly connected to one side of the folding bed, and the mountain-shaped fixing buckle has a slot that cooperates with the mountain-shaped positioning buckle.

[0010] Preferably, the limiting component includes a support rod and a hook, a fixed support frame is connected to the support rod, and an elastic plate is rotatably connected to the fixed support frame, the elastic plate being rotatably connected to one side of the folding bed.

[0011] Preferably, the folding bed is connected to a hinge frame, the elastic plate is rotatably connected to the hinge frame, and the hinge frame is located below the mountain-shaped fixing buckle.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: 1. This application adopts a double mountain-shaped snap-fit ​​structure that combines a mountain-shaped positioning snap-fit ​​with a mountain-shaped fixing snap-fit. This structure can be accurately embedded into the slot to achieve initial stable locking in the folded state. Compared with existing single snap-fit ​​or simple pin, it greatly improves the fit of the structure, effectively avoids loosening problems caused by transportation bumps or lateral forces, and enhances self-locking stability.

[0013] 2. This application further strengthens the folded state by adding a double limiting mechanism with elastic plates, connecting rods and hooks, on the basis of the mountain-shaped locking. The elastic return characteristics of the elastic plates can ensure that they fit the bed body without interfering with use when not in operation. At the same time, the double locking can completely prevent accidental unfolding caused by external force, which not only avoids space occupation, but also eliminates the risk of personnel bumping into each other, thus meeting the safety use requirements of the camping cabin.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-3 This utility model provides a technical solution: A self-locking mechanism for a camping cabin folding bed includes a connecting block 3. One end of the connecting block 3 is rotatably connected to a second folding hinge 2. One side of the second folding hinge 2 is rotatably connected to a first folding hinge 1. One side of the connecting block 3 is connected to a mountain-shaped positioning buckle 9. One side of the mountain-shaped positioning buckle 9 is connected to a mountain-shaped fixing buckle 4. A limiting member for limiting the position of the connecting block 3 is provided below the mountain-shaped fixing buckle 4. When the folding bed is opened, the connecting block 3 can be folded by rotation to achieve storage without taking up space and without touching the user.

[0018] Specifically, such as Figure 4 As shown, one end of the connecting block 3 is connected to a rotating shaft 8, which is rotatably connected to the folding hinge 2.

[0019] Specifically, such as Figure 1 and Figure 3 As shown, folding hinge 1 is fixedly connected to the upright on one side of the folding bed, and the upright and the folding bed are fixedly connected.

[0020] Specifically, such as Figure 4 As shown, the mountain-shaped fixing buckle 4 is fixedly connected to one side of the folding bed. The mountain-shaped fixing buckle 4 has a slot 10 that cooperates with the mountain-shaped positioning buckle 9. The mountain-shaped positioning buckle 9 completes the limitation of the structure when the folding bed is folded, thereby improving the stability of the folded state.

[0021] Specifically, such as Figure 4 and Figure 5 As shown, the limiting component includes a support rod 12 and a hook 7. A fixed support frame 6 is connected to the support rod 12. An elastic plate 5 is rotatably connected to the fixed support frame 6. The elastic plate 5 is rotatably connected to one side of the folding bed. The connection between the elastic plate 5 and the hinge frame 11 has an elastic mechanism, which ensures that the elastic plate 5 can fit against one side of the folding bed when there is no external force, so as not to affect the user's getting up and down.

[0022] Specifically, such as Figure 4 As shown, a hinge frame 11 is connected to the folding bed, and an elastic plate 5 is rotatably connected to the hinge frame 11. The hinge frame 11 is located below the mountain-shaped fixed buckle 4. The stability of the rotatable connection of the elastic plate 5 is improved by setting the hinge frame 11.

[0023] In summary, the self-locking mechanism of the camping cabin folding bed provided in this embodiment maintains the folded state of the folding bed and causes the second folding hinge 2 to rotate around the first folding hinge 1. At the same time, the connecting block 3 rotates on the second folding hinge 2, so that the mountain-shaped positioning buckle 9 is engaged in the slot 10 of the mountain-shaped fixing buckle 4.

[0024] Then flip the elastic plate 5 upwards to engage the rod 12 connected to one end of the fixed frame 6 with the buckle hook 7. Then flip the elastic plate 5 downwards to a vertical position to complete the self-locking of the camping cabin folding bed.

[0025] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
