Description

Technical Field

[0001] This utility model relates to the field of bed technology, and in particular to a single-layer folding bed frame structure and a single-layer folding bed. Background Technology

[0002] In modern home life, folding beds are widely popular due to their space-saving, portability, and ease of use, especially in small apartments, temporary accommodations, and outdoor camping. In traditional single-layer folding bed frame designs, to enhance stability and load-bearing capacity, a central support is typically installed in the middle of the frame. This central support often uses a double-leg connection, meaning it's connected to the main frame via two independent legs. While this structure improves stability to some extent, it also has the following drawbacks:

[0003] (1) Complex structure: The double-leg connection method requires additional connectors and fixing devices, resulting in a complex overall structure and increasing the difficulty of production and assembly.

[0004] (2) High cost: Due to the complex structure, the required materials and production processes are costly, which is not conducive to the market competitiveness of the product.

[0005] (3) Complex installation for users: Users need to assemble multiple parts during installation, which is cumbersome and usually requires the use of tools. This is not only time-consuming and laborious, but also prone to installation errors, affecting the user experience. Utility Model Content

[0006] In view of the shortcomings of the prior art described above, the technical problem to be solved by this utility model is to provide a single-layer folding bed frame structure and a single-layer folding bed, so as to solve the technical problems of complex single-layer folding bed frame structure, complicated user installation and poor user experience in the prior art.

[0007] To achieve the above objectives, this utility model provides a single-layer folding bed frame structure, comprising:

[0008] A bed frame assembly comprising at least two single-layer bed frames hinged to each other;

[0009] The middle leg assembly includes multiple middle leg components and rotating components disposed on each of the middle leg components. Two adjacent single-layer bed frames are hinged to each other through the rotating components. The two adjacent single-layer bed frames rotate at the hinge points with the rotating components, allowing the bed frame assembly to switch between an unfolded position where each single-layer bed frame is flush with the others and a folded-down position where each single-layer bed frame is folded up and close together. In the unfolded position, each single-layer bed frame rotates to form a first preset angle with the corresponding middle leg component, clamping the middle leg component between the ends of the two adjacent single-layer bed frames. In the folded-down position, the two adjacent single-layer bed frames rotate to be close to the corresponding middle leg component.

[0010] Two side tube assemblies are disposed on the outside of the bed frame assembly. Each side tube assembly includes a side tube component and a locking component disposed on the side tube component. The side tube component is hinged to the outer single-layer bed frame. In the unfolded position, the side tube component is rotated to form a second preset angle with the outer single-layer bed frame and is limited by the locking component. In the stowed position, the locking component is released, and the side tube component is rotated to fit against the outer single-layer bed frame.

[0011] In a preferred embodiment, the side leg component includes two first legs, a first connecting rod connecting the two first legs, and two support members; the first legs are hinged to the outer single-layer bed frame; the support members are respectively hinged to the first connecting rod and the outer single-layer bed frame; and the locking component is disposed on the support member.

[0012] In a preferred embodiment, the support member includes a first support tube and a second support tube. The first support tube is slidably fitted onto the second support tube. The first support tube is hinged to the first connecting rod, and the second support tube is hinged to the outer single-layer bed frame. The first support tube has a mounting hole, and the second support tube has a positioning hole. The locking component passes through the mounting hole and the positioning hole in sequence and connects to the second support tube, and can move within the positioning hole. In the unfolded position, the locking component moves into the positioning hole to limit the side tube component. In the retracted position, the locking component leaves the positioning hole, and the side tube component rotates to fit against the outer single-layer bed frame.

[0013] In a preferred embodiment, the locking component includes a housing, a handle mounted on the housing, a spring pin connected to the handle, and a spring sleeved on the spring pin. The housing is mounted on the first support tube and has a through hole. The spring pin passes sequentially through the through hole, the mounting hole, and the positioning hole to connect with the second support tube and can move within the positioning hole. In the unfolded position, the spring pin moves into the positioning hole under the action of the spring to limit the side tube component. In the retracted position, turning the handle causes the spring pin to leave the positioning hole, and the side tube component rotates to fit against the outer single-layer bed frame.

[0014] As a preferred embodiment, a first fixed seat is provided on the first connecting rod, and a second fixed seat is provided on the outer single-layer bed frame. The first support tube is hinged to the first fixed seat, and the second support tube is hinged to the second fixed seat.

[0015] As a preferred embodiment, the diameter of the first support pipe is larger than the diameter of the second support pipe.

[0016] In a preferred embodiment, the middle leg component includes two second legs and a second connecting rod connecting the two second legs, and the rotating component is disposed on the second legs.

[0017] In a preferred embodiment, the rotating component includes two rotating seats that are hinged to each other. Both rotating seats are mounted on the second support leg, and one end of each rotating seat is connected to one of the two adjacent single-layer bed frames, while the other ends of the two rotating seats are hinged to each other.

[0018] As a preferred embodiment, anti-slip mats are also included, which are respectively fitted onto the bottom of the middle leg tube component and the side leg tube component.

[0019] To achieve the above objectives, this utility model also provides a single-layer folding bed, comprising:

[0020] The single-layer folding bed frame structure described above;

[0021] A flexible support bed sheet is respectively fitted onto each of the single-layer bed frames; when the single-layer folding bed frame structure is in the unfolded position, the flexible support bed sheet is stretched open by each of the single-layer bed frames; when the single-layer folding bed frame structure is in the stowed position, the flexible support bed sheet is stowed.

[0022] As described above, the single-layer folding bed frame structure and single-layer folding bed involved in this utility model have the following beneficial effects:

[0023] When folding, the locking component of this utility model releases the restriction on the side leg tube component, and after rotating the two side leg tube components to fit against the outer single-layer bed frame, each single-layer bed frame is folded towards the middle from both sides of the bed frame assembly by rotating the component, so that each single-layer bed frame is folded together. At this time, the single-layer folding bed frame structure is in the storage position, and the folded structure is all fitted together. The folded structure is more compact, occupies less space, and is easy to carry and store. When the single-layer folding bed frame structure is unfolded, each single-layer bed frame rotates to a first preset angle with its corresponding middle leg component via a rotating component. Simultaneously, the two side leg components rotate to a second preset angle with the outer single-layer bed frame. Then, a locking component limits the side leg components, preventing them from rotating. All single-layer bed frames are now aligned, and each middle leg component is clamped between the ends of its two adjacent single-layer bed frames, preventing them from swinging. This ensures stable support for the bed frame assembly from the two side leg components and each middle leg component. At this point, the single-layer folding bed frame structure is in its unfolded position, facilitating load-bearing. The load-bearing capacity is enhanced, improving the overall load-bearing capacity of the bed frame assembly. This allows the single-layer folding bed frame structure to be unfolded and folded without tools, achieved solely through the hinges of each individual bed frame, the hinges between the side leg tube components and the outer single-layer bed frame, and the limiting effect of the locking components on the side leg tube components. Users can complete the entire unfolding and folding process simply by rotating and locking, avoiding cumbersome installation steps. The overall structure is simpler, reducing the number of parts, lowering production costs, and reducing the difficulty of production and assembly. This makes assembly convenient for users, enhancing market competitiveness and user experience.

[0024] When in use, the single-layer folding bed of this utility model unfolds the single-layer folding bed frame structure, and the flexible supporting bed fabric is stretched out by each of the single-layer bed frames, quickly forming a flat resting space. It can be used as a temporary bed, a rest chair, or an outdoor camping bed, meeting various usage scenarios. When storing the single-layer folding bed, the single-layer folding bed frame structure is folded, and the flexible supporting bed fabric is stored inside the single-layer folding bed frame structure, avoiding the trouble of separately organizing and storing the bed fabric, meeting storage needs, reducing space occupation, and facilitating storage and carrying. The single-layer folding bed can be quickly unfolded and stored by simply using the hinges of each single-layer bed frame, the hinges between the side leg tube components and the outer single-layer bed frame, and the limiting effect of the locking components on the side leg tube components. It also achieves tool-less assembly. Users only need to complete the entire unfolding and storage process through simple rotation and locking operations, avoiding cumbersome installation steps. The simple structure reduces the number of parts, lowers production costs, and reduces the difficulty of production and assembly, which is conducive to improving market competitiveness and user experience.

[0025] In summary, the single-layer folding bed frame structure and single-layer folding bed of this utility model, through the hinge of two single-layer bed frames, the hinge of the side leg tube components and the limiting effect of the locking components on the side leg tube components, can achieve the goal of unfolding and storing without the use of tools, avoiding cumbersome installation steps, which is conducive to improving market competitiveness and user experience. It has the advantages of convenient assembly, simple structure, saving storage space, reducing costs, and quick opening and closing. Attached Figure Description

[0067] like Figure 1-12As shown, this utility model provides a single-layer folding bed frame structure, comprising:

[0068] Bed frame assembly 1, the bed frame assembly 1 comprising at least two single-layer bed frames 11 hinged to each other;

[0069] The middle leg assembly 2 includes multiple middle leg components 21 and rotating components 22 disposed on each of the middle leg components 21. Two adjacent single-layer bed frames 11 are hinged to each other through the rotating components 22. The two adjacent single-layer bed frames 11 rotate at the hinge point with the rotating components 22, so that the bed frame assembly 1 switches between an unfolded position where each single-layer bed frame 11 is flush with the others and a folded-up position where each single-layer bed frame 11 is folded up and close together. In the unfolded position, each single-layer bed frame 11 rotates to form a first preset angle with the corresponding middle leg component 21, and clamps the middle leg component 21 between the ends of the two adjacent single-layer bed frames 11. In the folded-up position, the two adjacent single-layer bed frames 11 rotate to be close to the corresponding middle leg component 21.

[0070] Two side tube assemblies 3 are arranged on the outside of the bed frame assembly 1. Each side tube assembly 3 includes a side tube component 31 and a locking component 32 disposed on the side tube component 31. The side tube component 31 is hinged to the outer single-layer bed frame 11. In the unfolded position, the side tube component 31 is rotated to form a second preset angle with the outer single-layer bed frame 11 and is limited by the locking component 32. In the folded position, the locking component 32 is released and the side tube component 31 is rotated to fit against the outer single-layer bed frame 11.

[0071] To better illustrate the single-layer folding bed frame structure of this utility model, the following specific application will be used as an example: When the single-layer folding bed frame structure is folded, the locking component 32 is released from the limit of the side leg tube component 31, and the two side leg tube components 31 are rotated to fit against the outer single-layer bed frame 11. Then, each single-layer bed frame 11 is folded towards the middle from both sides of the bed frame assembly 1 by rotating component 22, so that each single-layer bed frame 11 is folded together. At this time, the single-layer folding bed frame structure is in the storage position, and the folded structure is all fitted together. The folded structure is more compact, occupies less space, and is easy to carry and store. When the single-layer folding bed frame structure is unfolded, each single-layer bed frame 11 is rotated by the rotating component 22 to form a first preset angle with the corresponding middle leg tube component 21. At the same time, the two side leg tube components 31 are rotated to form a second preset angle with the outer single-layer bed frame 11. Then, the locking component 32 limits the side leg tube components 31, preventing them from rotating. The single-layer bed frames 11 are in a flat state, and each middle leg tube component 21 is clamped between the ends of the two adjacent single-layer bed frames 11, preventing them from swinging. This allows the two side leg tube components 31 and each middle leg tube component 21 to provide stable support for the bed frame assembly 1. At this time, the single-layer folding bed frame structure is in the unfolded state. The open position facilitates load bearing and enhances the overall load-bearing capacity of the bed frame assembly 1. Thus, by simply using the hinges of each single-layer bed frame 11, the hinges between the side leg tube component 31 and the outer single-layer bed frame 11, and the limiting effect of the locking component 32 on the side leg tube component 31, the single-layer folding bed frame structure can be unfolded and stored without the use of tools. Users can complete the entire unfolding and storage process with just simple rotation and locking operations, avoiding cumbersome installation steps, making the overall structure simpler, reducing the number of parts, lowering production costs, and reducing the difficulty of production and assembly. It is convenient for users to assemble, which is conducive to improving market competitiveness and user experience.

[0072] In this embodiment, the first preset angle and the second preset angle include 90°.

[0073] In this embodiment, taking two single-layer bed frames 11 and one middle leg tube component 21 as an example, the process of unfolding and storing the single-layer folding bed frame structure is explained:

[0074] (1) When the single-layer folding bed frame structure is folded, the locking component 32 is released from the limit of the side leg tube component 31, and the two side leg tube components 31 are rotated to fit with the two single-layer bed frames 11. The two single-layer bed frames 11 are folded towards the middle by the rotating component 22, so that the two single-layer bed frames 11 are gathered and fitted at the middle leg tube component 21. At this time, the single-layer folding bed frame structure is in the storage position, the overall volume is reduced, and it is easy to store and carry.

[0075] (2) When the single-layer folding bed frame structure is unfolded, the two single-layer bed frames 11 are rotated by the rotating component 22 to form a first preset angle with the middle leg tube component 21. At the same time, the two side leg tube components 31 are rotated to form a second preset angle with the single-layer bed frame 11. Then, the locking component 32 limits the side leg tube component 31, so that the side leg tube component 31 cannot rotate. The two single-layer bed frames 11 are in a flat state, and the middle leg tube component 21 is clamped between the ends of the two single-layer bed frames 11, so that it cannot swing. This allows the two side leg tube components 31 and one middle leg tube component 21 to provide stable support for the bed frame assembly 1. At this time, the single-layer folding bed frame structure is in the unfolded position, and the two single-layer bed frames 11 are unfolded flat to form a complete bed surface.

[0076] In this embodiment, taking three single-layer bed frames 11 and two middle leg tube components 21 as an example, the process of unfolding and storing the single-layer folding bed frame structure is explained:

[0077] (1) When the single-layer folding bed frame structure is folded, the locking component 32 releases the restriction on the side leg tube component 31. After the two side leg tube components 31 are rotated to fit against the outer single-layer bed frame 11, the three single-layer bed frames 11 are folded towards the middle in sequence through the rotating component 22. First, one of the outer single-layer bed frames 11 is folded towards the middle so that it fits against the middle single-layer bed frame 11. Then, the other outer single-layer bed frame 11 is folded towards the middle so that it fits against the middle single-layer bed frame 11, so that the three single-layer bed frames 11 are folded together. At this time, the single-layer folding bed frame structure is in the storage position, the overall volume is reduced, and it is easy to store and carry.

[0078] (2) When the single-layer folding bed frame structure is unfolded, firstly, the middle single-layer bed frame 11 is fixed in place. Then, the two outer single-layer bed frames 11 are unfolded outward by rotating component 22, so that they are aligned with the middle single-layer bed frame 11. The two outer single-layer bed frames 11 and the corresponding middle leg tube component 21 are at a first preset angle. At the same time, the two side leg tube components 31 are rotated so that they are at a second preset angle with the outer single-layer bed frame 11. The side leg tube component 31 is limited by locking component 32 to ensure that the angle between the side leg tube component 31 and the single-layer bed frame 11 is fixed. Both middle leg tube components 21 are clamped in the middle by the two single-layer bed frames 11 connected to them, ensuring that the middle leg tube component 21 cannot swing. The side leg tube component 31, the middle leg tube component 21 and the single-layer bed frame 11 form a stable support structure. At this time, the single-layer folding bed frame structure is in the unfolded position, and the three single-layer bed frames 11 are unfolded in parallel to form a complete bed surface.

[0079] In this embodiment, taking four single-layer bed frames 11 and three middle leg tube components 21 as an example, the process of unfolding and storing the single-layer folding bed frame structure is explained:

[0080] (1) When the single-layer folding bed frame structure is folded, the locking component 32 releases the restriction on the side leg tube component 31, allowing the side leg tube component 31 to rotate freely. After rotating the two side leg tube components 31 to make them fit against the outer single-layer bed frame 11, the four single-layer bed frames 11 are folded towards the middle in sequence through the rotating component 22: First, one of the outer single-layer bed frames 11 is folded towards the middle to make it fit against the adjacent single-layer bed frame 11. Then, the other outer single-layer bed frame 11 is folded towards the middle to make it fit against the adjacent single-layer bed frame 11. Finally, the two middle single-layer bed frames 11 are folded towards the middle to make them fit together. At this time, the four single-layer bed frames 11 are folded together, and the single-layer folding bed frame structure is in the storage position, with a reduced overall volume, making it easy to store and carry.

[0081] (2) When the single-layer folding bed frame structure is unfolded, firstly, the two middle single-layer bed frames 11 are unfolded outwards by rotating component 22. Then, the two outer single-layer bed frames 11 are unfolded outwards by rotating component 22, so that they are flush with the middle single-layer bed frame 11. Each single-layer bed frame 11 is rotated to form a first preset angle with the corresponding middle leg tube component 21. At the same time, the two side leg tube components 31 are rotated to form a second preset angle with the outer single-layer bed frame 11. The side leg tube components 31 are limited by locking component 32 to ensure that the angle between the side leg tube components 31 and the single-layer bed frame 11 is fixed. The three middle leg tube components 21 are clamped in the middle by the two single-layer bed frames 11 connected to them, ensuring that the middle leg tube components 21 cannot swing. The side leg tube components 31, the middle leg tube components 21 and the single-layer bed frame 11 form a stable support structure. At this time, the single-layer folding bed frame structure is in the unfolded position, and the four single-layer bed frames 11 are unfolded flat to form a complete bed surface.

[0082] It should be noted that the number of the single-layer bed frame 11 and the middle leg tube component 21 described above is only one embodiment of this utility model, mainly used for explanation and illustration, and not for limiting the scope of protection of this utility model. In actual application, the number can be set according to the actual situation.

[0083] In this embodiment, as Figure 1-2As shown in Figures 4 and 6-12, the side leg component 31 includes two first legs 311, a first connecting rod 312 connecting the two first legs 311, and two support members 313. The first legs 311 are hinged to the outer single-layer bed frame 11. The support members 313 are hinged to the first connecting rod 312 and the outer single-layer bed frame 11, respectively. The locking component 32 is disposed on the support member 313. In the unfolded position, rotating the first legs 311 causes the support members 313 to rotate. When the first legs 311 rotate to a second preset angle with the outer single-layer bed frame 11, the locking component 32 restricts the rotation of the support members 313, preventing the first legs 311 from rotating. Thus, the four first legs 311 form a stable support, effectively preventing the single-layer folding bed frame structure from shaking or tilting during use, ensuring the stability and safety of the single-layer folding bed frame structure. When the storage position is reached, the locking component 32 is released, the first support leg 311 is rotated, and the support member 313 is rotated. All four first support legs 311 and four support members 313 are rotated until they fit against the outer single-layer bed frame 11, thus completing the storage.

[0084] In this embodiment, as Figure 1 , 2 As shown, the support member 313 includes a first support tube 3131 and a second support tube 3132. The first support tube 3131 is slidably sleeved on the second support tube 3132. The first support tube 3131 is hinged to the first connecting rod 312, and the second support tube 3132 is hinged to the outer single-layer bed frame 11. The first support tube 3131 is provided with a mounting hole, and the second support tube 3132 is provided with a positioning hole. The locking member 32 passes through the mounting hole and the positioning hole in sequence and is connected to the second support tube 3132, and can move within the positioning hole. In the unfolded position, the locking member 32 moves into the positioning hole to limit the side leg tube member 31. In the retracted position, the locking member 32 leaves the positioning hole, and the side leg tube member 31 rotates to fit against the outer single-layer bed frame 11.

[0085] In this embodiment, as Figure 1 , 2 As shown, the diameter of the first support tube 3131 is larger than the diameter of the second support tube 3132. One end of the first support tube 3131 is slidably sleeved on one end of the second support tube 3132, the other end of the first support tube 3131 is hinged to the first connecting rod 312, and the other end of the second support tube 3132 is hinged to the outer single-layer bed frame 11.

[0086] In this embodiment, as Figure 3As shown, the locking component 32 includes a housing 321, a handle 322 disposed on the housing 321, a spring pin 323 connected to the handle 322, and a spring 324 sleeved on the spring pin 323. The housing 321 is disposed on the first support tube 3131 and has a through hole. The spring pin 323 passes through the through hole, the mounting hole, and the positioning hole in sequence and is connected to the second support tube 3132, and can move within the positioning hole. In the unfolded position, the spring pin 323 moves into the positioning hole under the drive of the spring 324 to limit the side tube component 31. In the retracted position, when the handle 322 is turned, the spring pin 323 leaves the positioning hole, and the side tube component 31 is rotated to fit against the outer single-layer bed frame 11.

[0087] In this embodiment, as Figure 1-12 As shown, when the single-layer folding bed frame structure is folded, the handle 322 is turned, which moves the spring pin 323 away from the positioning hole on the second support tube 3132. The first support leg 311 is rotated, which causes the first support tube 3131 and the second support tube 3132 to slide relative to each other. The first support tube 3131 rotates along the hinge with the first connecting rod 312, and the second support tube 3132 rotates along the hinge with the outer single-layer bed frame 11. This causes the four first support legs 311 and the four support members 313 to rotate until they are in contact with the outer single-layer bed frame 11. Then, each single-layer bed frame 11 is folded from both sides of the bed frame assembly 1 towards the middle through the rotating component 22, so that each single-layer bed frame 11 is folded together and stored. At this time, the spring 324 on the spring pin 323 is in a compressed state, and the folded structure is all in contact with each other, with a small space ratio, making it easy to carry and store. When in use, each single-layer folding bed frame 11 is rotated by the rotating component 22 to form a first preset angle with the corresponding middle leg component 21. Then, the first support leg 311 is rotated, causing the first support tube 3131 and the second support tube 3132 to slide relative to each other. The first support tube 3131 rotates along the hinge with the first connecting rod 312, and the second support tube 3132 rotates along the hinge with the outer single-layer bed frame 11. When the first support leg 311 rotates to form a second preset angle with the outer single-layer bed frame 11, the spring 324 releases its elastic force, causing the spring pin 323 to move into the positioning hole on the second support tube 3132 to lock the first support tube 3131 and the second support tube 3132, so that the first support tube 3131 and the second support tube 3132 stop rotating, and each first support leg 311 and each second support leg 211 form a stable support. In this way, users can complete the entire unfolding and folding process simply by rotating and locking, without the need for additional tools and avoiding complicated operation steps, making installation convenient and saving users installation time.

[0088] In this embodiment, as Figure 1 , 4 As shown in Figure 6-11, a first fixed seat 3121 is provided on the first connecting rod 312, and a second fixed seat 111 is provided on the outer single-layer bed frame 11. The first support tube 3131 is hinged to the first fixed seat 3121, and the second support tube 3132 is hinged to the second fixed seat 111. The other end of the first support tube 3131 is hinged to the first fixed seat 3121, and the other end of the second support tube 3132 is hinged to the second fixed seat 111. When the spring pin 323 moves into the positioning hole on the second support tube 3132 under the action of the spring 324, it locks the first support tube 3131 and the second support tube 3132. The first support tube 3131 cannot rotate along the hinge point with the first fixed seat 3121, and the second support tube 3132 cannot rotate along the hinge point with the second fixed seat 111, so that the first support leg 311 can be stably supported. When the spring pin 323 leaves the positioning hole under the action of external force, the first support tube 3131 and the second support tube 3132 slide relative to each other, and drive the first support tube 3131 to rotate along the hinge with the first fixed seat 3121, and the second support tube 3132 to rotate along the hinge with the second fixed seat 111, so that the first leg 311 rotates to fit against the outer single-layer bed frame 11.

[0089] In this embodiment, as Figure 1 , 4 As shown in Figure -12, the middle leg component 21 includes two second legs 211 and a second connecting rod 212 connecting the two second legs 211. The rotating component 22 is disposed on the second legs 211. There are two rotating components 22. Each rotating component 22 includes two hinged rotating seats 221, both of which are disposed on the second legs 211. One end of each rotating seat 221 is connected to one of the two adjacent single-layer bed frames 11, and the other ends of the two rotating seats 221 are hinged to each other. In the unfolded position, the two adjacent single-layer bed frames 11 rotate through the rotating seats 221 to form a first preset angle with the second legs 211, clamping the corresponding two second legs 211 in the middle, preventing them from swinging. Under the weight of the single-layer bed frame 11, the second legs 211 are stably clamped by the single-layer bed frame 11. The heavier the single-layer bed frame 11, the more stable the clamping. Each first leg 311 and each second leg 211 provides stable support for the bed frame assembly 1. In the storage position, two adjacent single-layer bed frames 11 can be rotated via the swivel base 221 until they are in contact with the corresponding second support leg 211. Users can easily unfold and fold each single-layer bed frame 11 with a simple rotation operation.

[0090] In this embodiment, as Figure 1-2As shown in Figures 4 and 6-12, the system also includes anti-slip pads 4, which are respectively fitted onto the bottom of the middle leg tube component 21 and the side leg tube component 31. The anti-slip pads 4 are fitted onto the bottom of each first leg 311 and each second leg 211 to increase the friction between the middle leg tube component 21 and the side leg tube component 31 and the ground, preventing the single-layer folding bed frame structure from sliding during use and improving the stability of the single-layer folding bed frame structure.

[0091] This utility model also provides a single-layer folding bed, comprising:

[0092] The single-layer folding bed frame structure described above;

[0093] A flexible support bed sheet is respectively fitted onto each of the single-layer bed frames 11; when the single-layer folding bed frame structure is in the unfolded position, the flexible support bed sheet is stretched open by each of the single-layer bed frames 11; when the single-layer folding bed frame structure is in the stowed position, the flexible support bed sheet is stowed.

[0094] To better illustrate the single-layer folding bed of this utility model, the following specific application will be used as an example: When in use, the single-layer folding bed frame structure is unfolded, and the flexible supporting bedclothes are stretched out by each of the single-layer bed frames 11, quickly forming a flat resting space. It can be used as a temporary bed, a rest chair, or an outdoor camping bed, meeting various usage scenarios. When storing, the single-layer folding bed frame structure is folded, and the flexible supporting bedclothes are stored within the single-layer folding bed frame structure. This avoids the hassle of separately organizing and storing the bedclothes, meets storage needs, reduces space occupation, and facilitates storage and portability. By simply connecting the individual single-layer bed frames 11, connecting the side leg tube components 31 to the outer single-layer bed frame 11, and limiting the side leg tube components 31 with the locking component 32, the single-layer folding bed can be quickly unfolded and stored, achieving tool-free assembly. Users can complete the entire unfolding and storage process with just simple rotation and locking operations, avoiding cumbersome installation steps. The simple structure reduces the number of parts, lowers production costs, and reduces the difficulty of production and assembly, which is conducive to improving market competitiveness and user experience.

[0095] In summary, the single-layer folding bed frame structure and the single-layer folding bed of this utility model have the following advantages:

[0096] (1) Space saving and portability: When the single-layer folding bed frame structure is folded, each single-layer bed frame 11 is folded in half to the middle through the rotating part 22 and snug together. The folded structure is more compact and has a small space ratio, making it easy to carry and store. It is especially suitable for scenarios with limited space (such as camping, temporary accommodation, etc.), which improves the portability and applicability of the bed frame.

[0097] (2) Easy to operate and improve user experience: Users can unfold and store the bed frame by simply rotating and locking it without using tools, avoiding tedious installation steps. The operation is simple, saving users' assembly time and improving the user experience. It is especially suitable for non-professional users to operate quickly.

[0098] (3) Simple structure and reduced cost: Through the hinge of the single-layer bed frame 11, the hinge of the side leg tube component 31 and the limiting effect of the locking component 32, the overall structure is simpler, the number of parts is reduced, the production cost is reduced, and the difficulty of production and assembly is simplified, which is conducive to improving market competitiveness.

[0099] (4) Stability and load-bearing capacity: In the unfolded position, each single-layer bed frame 11 unfolds horizontally, the middle leg tube component 21 is clamped between two adjacent single-layer bed frames 11, and the side leg tube component 31 is limited by the locking component 32 to form a stable support structure, which enhances the overall load-bearing capacity of the bed frame assembly 1, enabling it to bear a larger load and improve the practicality and durability of the bed frame.

[0100] (5) Multifunctionality and applicability: The single-layer folding bed frame structure and the single-layer folding bed are suitable for a variety of scenarios, such as home, camping, temporary accommodation, etc. Through simple structural design, the use needs of different scenarios are met, and the multifunctionality and market adaptability of the product are improved.

[0101] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
