Description

Technical Field

[0001] This utility model relates to the field of folding bed technology, specifically a double-layer folding storage bed. Background Technology

[0002] A folding bed is a simple bed designed using the principle of joints. It can be folded and stored in various ways to save space and is convenient and practical for easy storage.

[0003] Currently used bunk beds or folding beds typically employ simple folding structures, which can only achieve planar folding of the bed board and cannot fully utilize vertical space for storage. Existing folding beds still occupy a lot of space when folded, or require complete disassembly for storage, making them inconvenient to use. Therefore, a double-layer folding storage bed is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a double-layer folding storage bed, which has the advantages of allowing the middle of the bed board to be arched and folded into the cabinet, saving indoor space, and being easy to store. It solves the problems of folding beds requiring complete disassembly, inconvenience in use, and large space occupation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a double-layer folding storage bed, comprising two support frames and a cabinet, wherein the support frame on the right is fixedly installed inside the cabinet, and two sets of left bed frames and a right bed frame are provided between the two support frames, and a bed frame connection structure for fixing the left bed frame and the right bed frame is provided at the connection between the two sets of left bed frames and the right bed frame;

[0006] Two sets of bed frame fixing ribs are fixed on the front and back of both support frames. The two sets of bed frame fixing ribs on the left support frame are rotatably connected to the left side of the two sets of left bed frames through a connecting shaft. The two sets of bed frame fixing ribs on the right support frame are rotatably connected to the right side of the two sets of right bed frames through a connecting shaft. Two wheel frames are installed at the bottom of the left support frame. Four hydraulic cylinders are inclined at the vertical angle between the opposite side of the two support frames and the bottom left and right bed frames. A climbing ladder structure is provided on the front of the two sets of left bed frames to facilitate climbing.

[0007] Furthermore, the two sets of left and right bed frames are arranged horizontally when unfolded, and the two sets of left and right bed frames are folded upwards and arched, so that the entire bed can be stored in the cabinet's storage space.

[0008] Furthermore, the bed frame connection structure includes two fixed discs, a shaft, and two sleeves. The two fixed discs are respectively fixedly installed on the front and back of the left bed frame. The shaft is movably installed between the two fixed discs through bearings. The two sleeves are both sleeved on the outer surface of the shaft, and the tops of the two sleeves are also fixed to the bottom of the right bed frame.

[0009] Furthermore, two support rods are movably mounted on the two fixed plates on the back of the two left bed frames via connecting shafts, and the bottom of the support rods is flush with the bottom of the support frame.

[0010] Furthermore, the ladder structure includes two ladder longitudinal bars and multiple ladder transverse bars. The two ladder longitudinal bars are vertically arranged on the front of the two left bed frames and are arranged in parallel. The multiple ladder transverse bars are movably installed between the two ladder longitudinal bars through a connecting shaft.

[0011] Furthermore, the bottom of the two ladder longitudinal bars is flush with the bottom of the support frame, and the two ladder longitudinal bars and the two left bed frames are movably installed via bearings. The multiple ladder crossbars are also movably installed between the two ladder longitudinal bars via bearings.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] 1. This double-layer folding storage bed uses an upward-pushing support rod to arch the fixed plate on the left bed frame and the sleeve on the right bed frame around the axis rod. At the same time, the connecting shaft between the left and right bed frames and the bed frame fixing ribs also allows the left and right bed frames to be flipped to achieve the folding effect. Finally, the fully folded support frame is pushed into the cabinet to achieve the function of conveniently folding the storage bed and saving indoor space.

[0014] 2. This double-layer folding storage bed uses a wheel frame at the bottom to facilitate the pushing and folding of the left support frame, and four hydraulic cylinder struts to support the left and right bed frames. Attached Figure Description

[0019] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 The double-layer folding storage bed in this embodiment includes two support frames 1 and a cabinet 4. The support frames 1 provide support for the entire storage bed. The cabinet 4 has an internal space to store the fully folded folding bed. The support frame 1 on the right side is fixedly installed inside the cabinet 4. Two sets of left bed frames 2 and right bed frames 3 are provided between the two support frames 1. The connection between the two sets of left bed frames 2 and right bed frames 3 is provided with a bed frame connection structure 5 for fixing the left bed frame 2 and right bed frame 3.

[0021] Two sets of bed frame fixing ribs 7 are fixed on the front and back of the two support frames 1. The bed frame fixing ribs 7 are the connecting parts of the two sets of left bed frames 2 and right bed frames 3 to the two support frames 1. The two sets of bed frame fixing ribs 7 on the left support frame 1 are rotatably connected to the left side of the two sets of left bed frames 2 through a connecting shaft. The two sets of bed frame fixing ribs 7 on the right support frame 1 are rotatably connected to the right side of the two sets of right bed frames 3 through a connecting shaft. Two wheel frames 8 are installed at the bottom of the left support frame 1 to facilitate the left support frame 1 to move closer to the right support frame 1. Four hydraulic cylinders 10 are inclined at the vertical angle between the opposite side of the two support frames 1 and the bottom left bed frames 2 and right bed frames 3 to support the left bed frames 2 and right bed frames 3. The front of the two sets of left bed frames 2 is provided with a climbing ladder structure 6 to facilitate climbing.

[0022] The two sets of left bed frames 2 and right bed frames 3 are arranged horizontally when unfolded. When unfolded, the two sets of left bed frames 2 and right bed frames 3 are folded upwards and arched, so that the entire bed can be stored in the storage space of the cabinet 4.

[0023] It should be noted that there is a certain gap between the left support frame 1 and the two sets of left bed frames 2, allowing the two sets of left bed frames 2 to have some room to move when folded. Similarly, there is a certain gap between the right support frame 1 and the two sets of right bed frames 3, allowing the two sets of right bed frames 3 to have some room to move when folded. Foldable anti-fall guardrails can be installed on the edges of the top left bed frames 2 and right bed frames 3. After folding, the anti-fall guardrails can be laid flat on the bed boards of the left bed frames 2 and right bed frames 3 without restricting the folding of the left bed frames 2 and right bed frames 3. When the bottom left bed frames 2 and right bed frames 3 are laid flat, the four hydraulic cylinders 10 underneath also reach the minimum range that can be shortened to provide support.

[0024] Specifically, when the storage bed needs to be folded or unfolded, the left support frame 1 can be pushed towards the right support frame 1 under the action of the wheel frame 8. This causes the connection between the two sets of left bed frames 2 and right bed frames 3 to arch upward at the bed frame connection structure 5. The bottom left bed frames 2 and right bed frames 3 will also pull the four hydraulic cylinders 10 on the two support frames 1 to unfold and no longer support the left bed frames 2 and right bed frames 3. At the same time, the ladder structure 6 will also tilt along with the two left bed frames 2 until the left support frame 1 is completely retracted into the cabinet 4, thus completing the entire storage process.

[0025] In this embodiment, the bed frame connection structure 5 includes two fixed plates 501, a shaft 502, and two sleeves 503. The two fixed plates 501 are fixedly installed on the front and back of the left bed frame 2, respectively. The shaft 502 is movably installed between the two fixed plates 501 through bearings. The two sleeves 503 are both sleeved on the outer surface of the shaft 502, and the tops of the two sleeves 503 are also fixed to the bottom of the right bed frame 3.

[0026] Among them, the two fixed plates 501 on the back of the two left bed frames 2 are movably mounted with support rods 9 via connecting shafts, and the bottom of the support rods 9 is flush with the bottom of the support frame 1.

[0027] It should be noted that the strut 9 being flush with the bottom of the support frame 1 can serve as an intermediate support.

[0028] Specifically, when the bed frame connecting structure 5 is needed to fold the left bed frame 2 and the right bed frame 3, the axle 502 at the bottom center of the left bed frame 2 and the right bed frame 3 serves as the central axis. While the central axis remains unchanged, the left bed frame 2 rotates with two fixed discs 501 as connectors, and the right bed frame 3 rotates with two sleeves 503 as connectors, thereby bending the middle of the left bed frame 2 and the right bed frame 3.

[0029] In this embodiment, the ladder structure 6 includes two ladder vertical bars 601 and multiple ladder horizontal bars 602. The two ladder vertical bars 601 are vertically arranged on the front of the two left bed frames 2 and are arranged in parallel. The multiple ladder horizontal bars 602 are movably installed between the two ladder vertical bars 601 through connecting shafts.

[0030] The bottom of the two ladder longitudinal bars 601 is flush with the bottom of the support frame 1. The two ladder longitudinal bars 601 and the two left bed frames 2 are movably installed through bearings. The multiple ladder cross bars 602 are also movably installed between the two ladder longitudinal bars 601 through bearings.

[0031] It should be noted that the bottom of the ladder vertical bar 601 is flush with the bottom of the support frame 1, which can also serve to support the left bed frame 2 and the right bed frame 3. When the two left bed frames 2 are folded and arched, the right side of the multiple ladder horizontal bars 602 rotates and tilts through the bearing.

[0032] Specifically, when a ladder structure 6 is needed for a user to climb onto the bed, the user can climb onto the bed by holding onto the ladder vertical bar 601 and stepping on multiple ladder horizontal bars 602.
