[0002] The reinforced structure of a sofa bed refers to a series of structural design and reinforcement measures adopted in the design and manufacture of a sofa bed to improve its stability, safety, load-bearing capacity, and service life. These measures may include using stronger materials, adding support structures, and improving connection methods.

[0003] Currently, existing sofa bed reinforcement structures typically include strengthening the sofa bed's sturdiness, durability, safety, and functionality. Among these, the safety reinforcement structure usually uses guardrails to prevent people from falling, thus achieving the effect of enhancing the sofa bed's safety. Although guardrails can enhance the safety of the sofa bed, they are usually not convenient to fold and store, which can easily affect people when they are sitting or resting, and can also cause inconvenience when sitting or standing. Therefore, those skilled in the art provide a sofa bed reinforcement structure to solve the problems mentioned in the background art. Utility Model Content

[0004] In view of this, it is necessary to provide a reinforced structure for sofa beds to solve the problem of the inconvenience of folding and storing the guardrails.

[0005] According to one aspect of this utility model, a reinforcing structure for a sofa bed is provided, comprising two crossbeams, with a bed frame fixedly connected to the outer surfaces of the two crossbeams. A protective railing is rotatably connected to the outer surface of the bed frame. Two limiting blocks are slidably connected to the inner wall of the bed frame. The outer surface of each limiting block is slidably connected to the inner wall of the protective railing. A spring is fixedly connected to one side of each limiting block that is close to each other. The ends of each spring that are close to each other are fixedly connected to the inner wall of the bed frame. A rotating column is rotatably connected to the inner wall of each limiting block. A baffle is fixedly connected to one end of each rotating column that is close to each other. Two stops are fixedly connected to the upper surface of the bed frame.

[0006] According to some embodiments, each of the crossbeams is fixedly connected to a column on both the front and back sides, and each of the columns is fixedly connected to a base on its bottom surface.

[0007] According to some embodiments, each set of columns has a side support fixedly connected to the side of each column that is close to each other, and a storage frame fixedly connected to the side of each of the two side supports that is far from each other.

[0008] According to some embodiments, a bed frame is fixedly connected to the upper surface of each set of columns, and an anti-wear pad is fixedly connected to the outer surface of each bed frame.

[0009] According to some embodiments, a backrest is fixedly connected to the upper surface of one of the beams, and an anti-slip pad is fixedly connected to the left side of the backrest.

[0010] According to some embodiments, the inner wall of the bed frame is fixedly connected with three magnetic pieces, and the outer surfaces of the two crossbeams are jointly fixedly connected with eleven crossbars.

[0011] According to some embodiments, each of the crossbars has two reinforcing blocks fixedly connected to its front and back sides, and the bottom surface of each reinforcing block is fixedly connected to the upper surface of the crossbeam.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] By incorporating a guardrail and a limiting block, the limiting block effectively restricts the guardrail's movement, preventing falls and ensuring the sofa bed's safety. When the guardrail is no longer needed, the limiting block can be pulled back, causing it to move and disengage its pin from the guardrail until it is completely detached. This releases the guardrail from its restraint, allowing it to be easily folded and stored inside the bed frame. This solves the problem of existing guardrails being inconvenient to fold and store, preventing discomfort and discomfort when people are sitting or resting. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0021] Please see Figures 1 to 4 This utility model provides a reinforced structure for a sofa bed, including two crossbeams 1. The outer surfaces of the two crossbeams 1 are fixedly connected to a bed frame 2. The outer surface of the bed frame 2 is rotatably connected to a guardrail 13. The inner wall of the bed frame 2 is slidably connected to two limiting blocks 15. The outer surface of each limiting block 15 is slidably connected to the inner wall of the guardrail 13. The sides of the two limiting blocks 15 that are close to each other are fixedly connected to springs 16. The ends of the two springs 16 that are close to each other are fixedly connected to the inner wall of the bed frame 2. The inner wall of each limiting block 15 is rotatably connected to a rotating column 17. The ends of the two rotating columns 17 that are close to each other are fixedly connected to a baffle 18. The upper surface of the bed frame 2 is fixedly connected to two stops 19.

[0022] By using the baffle 18 and the stop block 19, it is convenient to block the guardrail 13 after the limit block 15 releases its limit, thus preventing the limit block 15 from resetting when the guardrail 13 is folded.

[0023] Furthermore, each crossbeam 1 is fixedly connected to a column 3 on both the front and back, and each column 3 is fixedly connected to a base 4 on its bottom surface. The column 3 serves as a support, connecting the crossbeam 1 to the base 4. The base 4 increases the stability of the entire sofa bed structure, preventing the sofa bed from wobbling or tipping over during use. This is because the crossbeam 1 is the lateral support of the entire structure, the column 3 provides vertical support, and the base 4 provides a solid bottom support for the entire structure, allowing the sofa bed to withstand greater weight and external forces, thus improving the sofa bed's durability.

[0024] Furthermore, each set of uprights 3 has a side panel 5 fixedly connected to the side of each pair of uprights 3 that is close to each other, and a storage frame 6 fixedly connected to the side of each pair of side panels 5 that is far from each other. The side panels 5 can enhance the connection between the uprights 3, making the whole structure more compact. The storage frame 6 fixedly connected to the side of each pair of side panels 5 that is far from each other provides users with extra storage space, which can be used to store some commonly used items, such as magazines and blankets, increasing the functionality of the sofa bed.

[0025] Furthermore, each set of uprights 3 has a bed frame 9 fixedly connected to its upper surface, and each bed frame 9 has an anti-wear pad 10 fixedly connected to its outer surface. The bed frame 9 can increase the protection effect at both ends of the sofa bed, and at the same time increase the overall integrity of the sofa bed. The anti-wear pad 10 can reduce the friction between the bed frame 9 and other items.

[0026] Furthermore, a backrest 7 is fixedly connected to the upper surface of one of the crossbeams 1, and an anti-slip pad 8 is fixedly connected to the left side of the backrest 7. The backrest 7 provides support for the user and increases the comfort of the sofa bed. The anti-slip pad 8 can prevent the user from sliding when leaning against the backrest 7, thus improving the safety and comfort of use.

[0027] Furthermore, three magnetic pieces 14 are fixedly connected to the inner wall of the bed frame 2, and eleven crossbars 11 are fixedly connected to the outer surfaces of the two crossbeams 1. The magnetic pieces 14 may be used to attract other magnetic components or to play a positioning role, so that the guardrail 13 can be attracted and limited after being folded. The crossbars 11 can enhance the connection strength between the crossbeams 1, making the entire sofa bed frame more stable and improving the overall strength of the structure.

[0028] Furthermore, two reinforcing blocks 12 are fixedly connected to the front and back of each crossbar 11. The bottom surface of each reinforcing block 12 is fixedly connected to the upper surface of the crossbeam 1. The reinforcing blocks 12 further enhance the connection between the crossbar 11 and the crossbeam 1. The bottom surface of each reinforcing block 12 is fixedly connected to the upper surface of the crossbeam 1, so that the crossbar 11 can better play its role in enhancing the structural strength and ensure that the entire sofa bed will not experience structural loosening or other problems during long-term use.

[0029] Working Principle: In use, the sofa bed's crossbeam 1, uprights 3, and side panels 2 form the basic frame. Side panels 2 have safety railings 13, which prevent falls and ensure the sofa bed's safety. When the safety railings 13 are not needed, the user pulls the limiting block 15 backward. The limiting block 15 moves under the pulling action, allowing its pin to be pulled out from inside the safety railing 13. Simultaneously, the movement of the limiting block 15 drives the rotating column 17 and the baffle 18 to move, compressing the spring 16 until the limiting block 15 moves to the point where its pin is completely disengaged from the safety railing 13, thus releasing it from its limiting position. Once the limiting block 15 reaches the released position... The position of the baffle 18 will also extend beyond the stop block 19. Then, the staff can rotate the rotating column 17 to adjust the baffle 18 to a suitable angle. This allows the baffle 18 and the stop block 19 to work together to block and prevent the limit block 15 from resetting. After that, the staff can easily release the limit on the other side of the guardrail 13 until both limits are released. Then, the guardrail 13 can be easily rotated, folded, and stored inside the bed frame 2. The magnetic piece 14 inside the bed frame 2 can easily attract the guardrail 13, preventing the guardrail 13 from shaking during storage. Since the guardrail 13 is made of metal, this solves the problem that the existing guardrail 13 is inconvenient to fold and store, and avoids affecting or making it inconvenient for people to sit or rest.
