Description

Technical Field

[0001] This utility model relates to a compression sofa, specifically a portable compression sofa, and belongs to the technical field of sofas. Background Technology

[0002] Sofas, filled with high-density foam, springs, and other materials, are designed to conform to the curves of the human body, providing a relaxing sitting or lying experience. For example, American-style sofas emphasize a sense of envelopment, while upholstered sofas use soft materials to reduce body fatigue. Some sofas also have their depth adjusted according to ergonomics (such as 95cm, suitable for people under 1.7 meters tall) to further enhance back support. They are versatile and practical, and sofas are not only for rest but can also be expanded to have multiple uses. For example, sofas with storage compartments can save space, some sofas can be converted into beds to meet temporary sleeping needs, and upholstered sofas can also be freely spliced ​​and combined to flexibly adapt to different apartment layouts.

[0003] However, existing sofas are relatively heavy due to their large structure and size, making them inconvenient to move and relocate, especially when frequent relocations or moving to higher floors are required. This makes handling difficult and increases the risk and workload of moving the sofa. To address these issues, we provide a portable compression sofa. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a portable compression sofa, the specific technical solution of which is as follows:

[0005] A portable compression sofa includes a base plate, a sponge pad on the upper surface of the base plate, a sponge backrest fixedly connected to the outer surface of the sponge pad, a sponge armrest fixedly connected to the outer surface of the sponge pad, the outer surface of the sponge armrest being fixedly connected to the outer surface of the sponge backrest, a sponge cover plate slidably connected to the outer surface of the sponge pad, a back panel slidably connected to the outer surface of the base plate, and legs provided on the bottom surface of the base plate.

[0006] Preferably, the upper surface of the sponge pad has a cavity, the cavity contains a spring pack, and the outer surface of the sponge cover is slidably connected to the inner wall of the cavity.

[0007] Preferably, the outer surface of the base plate is provided with a groove, the inner wall of the groove is slidably connected with a concave plate, and the outer surface of the concave plate is fixedly connected to the outer surface of the back plate.

[0008] Preferably, a fixing groove is formed on the outer surface of the base plate, and a fixing plate is slidably connected to the inner wall of the fixing groove, with the outer surface of the fixing plate in contact with the outer surface of the concave plate.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This portable compression sofa utilizes the interplay of a sponge pad, sponge cover, back panel, legs, and spring packs. When transporting the device, the sponge pad, backrest, and armrests are removed from the top surface of the base plate, compressed, and then the back panel is slid off the base plate, separating the back panel from the base plate into two sections. The legs are then unscrewed from their threaded sleeves. This allows the sofa to be disassembled for easy transport. This solution addresses the problem of existing sofas being too large and heavy, making them inconvenient to move, especially during frequent relocations or when moving to higher floors, increasing the risk and workload of transport.

[0014] 2. This portable compression sofa uses the cooperation between the base plate, through groove, sponge pad and protrusion to place the sponge pad on the upper surface of the base plate and to lock the protrusion inside the through groove. This prevents the sponge pad from sliding on the upper surface of the base plate and causing misalignment between the base plate and the sponge pad, thus facilitating the fixing and disassembly of the sponge pad.

[0021] The present invention will now be further described with reference to the accompanying drawings.

[0022] Please see Figure 1-5 As shown, a portable compression sofa includes a base plate 1. A sponge pad 2 is provided on the upper surface of the base plate 1. The sponge pad 2 is a high-density sponge pad. The high-density sponge achieves high support and resilience through a tightly arranged micro-pore structure, which can effectively disperse pressure and conform to the body curve. Its high density means small gaps and high hardness, but the softness and hardness can be adjusted by adding additives, so as to balance the support and comfort of the sofa. A sponge backrest 3 is fixedly connected to the outer surface of the sponge pad 2.

[0023] The bottom surface of the base plate 1 is provided with a through groove 14, and the bottom surface of the sponge pad 2 is connected with a protrusion 15. The outer surface of the protrusion 15 is slidably connected to the inner wall of the through groove 14. One through groove 14 corresponds to one protrusion 15. When the sponge pad 2 is placed on the upper surface of the base plate 1, the protrusion 15 is locked inside the through groove 14, which can prevent the sponge pad 2 from sliding on the upper surface of the base plate 1 and causing misalignment between the base plate 1 and the sponge pad 2.

[0024] A sponge armrest 4 is fixedly connected to the outer surface of the sponge pad 2. The outer surface of the sponge armrest 4 is fixedly connected to the outer surface of the sponge backrest 3. A sponge cover plate 5 is slidably connected to the outer surface of the sponge pad 2. The sponge backrest 3, sponge pad 2, sponge armrest 4 and sponge cover plate 5 are all made of high-density sponge. There are two sponge armrests 4, which are symmetrically distributed.

[0025] The upper surface of the sponge pad 2 has a cavity 8, and a spring pack 9 is installed inside the cavity 8. The outer surface of the sponge cover plate 5 is slidably connected to the inner wall of the cavity 8. A spring is installed inside the spring pack 9. Several spring packs 9 form a whole, and the outer surface is covered with sponge. The combination of sponge pad 2 and spring pack 9 can greatly enhance the cushioning performance. The sponge has a porous structure and has good shock absorption performance, while the spring inside the spring pack 9 can absorb energy through its own elastic deformation. Therefore, the combination of sponge and spring can effectively absorb external impact and provide a better cushioning effect.

[0026] A back plate 6 is slidably connected to the outer surface of the base plate 1. A groove 10 is formed on the outer surface of the base plate 1. A concave plate 11 is slidably connected to the inner wall of the groove 10. The outer surface of the concave plate 11 is fixedly connected to the outer surface of the back plate 6. The concave plate 11 is aligned with the groove 10 and pushed in to install it. This allows the back plate 6 to be installed together with the base plate 1, which facilitates installation. Lubricating oil is applied to the outer surface of the concave plate 11 to reduce the friction between the concave plate 11 and the groove 10, making it easier for the concave plate 11 to slide on the inner wall of the groove 10. Long grooves are formed on the outer surface of the back plate 6 and are evenly distributed to ensure the breathability of the sponge backrest 3.

[0027] A fixing groove 12 is provided on the outer surface of the base plate 1. A fixing plate 13 is slidably connected to the inner wall of the fixing groove 12. The outer surface of the fixing plate 13 is in contact with the outer surface of the concave plate 11. By fixing the fixing plate 13 in the inner wall of the fixing groove 12, the two ends of the concave plate 11 can be restricted, preventing the concave plate 11 from sliding on the inner wall of the groove 10 and limiting the movement of the concave plate 11.

[0028] The bottom surface of the base plate 1 is provided with four legs 7, which are symmetrically distributed. The bottom end of the legs 7 is connected to a rubber pad to prevent noise when moving the sofa. The bottom surface of the base plate 1 is connected to a threaded cylinder 16, and the threaded cylinder 16 is connected to a threaded rod 17. The bottom end of the threaded rod 17 is connected to the top end of the legs 7. By unscrewing the threaded rod 17 from the threaded cylinder 16, the legs 7 can be separated from the base plate 1, and the sofa can be disassembled for easy packing and transportation.

[0029] There are two fixing plates 13, which are symmetrically distributed on the outer surface of the base plate 1. The fixing plates 13 are rectangular in shape, and one fixing groove 12 corresponds to one fixing plate 13. There are two fixing grooves 12, located at both ends of the base plate 1.

[0030] When using this utility model: When the device needs to be transported, the sponge cover plate 5 is removed from the inside of the sponge pad 2, the spring pack 9 is removed, and the sponge pad 2, sponge backrest 3 and sponge armrest 4 are a whole. The whole is removed from the upper surface of the base plate 1. At this time, the protrusion 15 will slide on the inner wall of the through groove 14 to compress the sponge pad 2, sponge backrest 3 and sponge armrest 4. Then, the fixing plate 13 is removed from the inner wall of the fixing groove 12, and the back plate 6 is slid out of the base plate 1. At this time, the concave plate 11 slides on the inner wall of the groove 10 to separate the back plate 6 and the base plate 1 into two pieces. Then, the threaded rod 17 is unscrewed from the threaded cylinder 16 to separate the support leg 7 from the base plate 1. The sofa can be disassembled for easy packing and transportation.
