Description

Technical Field

[0001] The utility model relates to the technical field of sofas, in particular to a sofa with a liftable bottom. Background Art

[0002] In modern home furnishings, a sofa refers to a chair with a backrest equipped with springs or thick foam plastic cushions, usually with armrests on both sides. The overall shape and function is to provide people with a comfortable space for sitting, lying or reclining. Sofas of different colors, materials, shapes and sizes can create different home atmospheres, making people feel warm, comfortable or fashionable. They not only provide people with a comfortable sitting and lying space, but are also an indispensable part of home design.

[0003] After searching, a Chinese patent with application number CN202222455951.0 discloses a sofa that prevents dust accumulation. For existing sofas, since the base of the sofa is directly fixed to the backrest of the sofa, when a person sits on the sofa and leans against the backrest of the sofa, the dust on the back of the clothes can easily fall from the gap between the seat cushion and the backrest to the connection between the backrest and the base. The connection between the backrest and the base of the sofa is difficult to clean after dust accumulates. Therefore, when a person sits on the sofa and leans against the backrest of the sofa, the dust on the back of the clothes will fall into the receiving groove along the dust leakage hole, and there will be no problem of dust accumulation at the connection between the backrest and the base of the sofa.

[0004] During use, the above-mentioned sofa is only convenient for cleaning accumulated dust, and the height of the bottom of the sofa is usually fixed, which makes it inconvenient to flexibly lift the bottom of the sofa according to the user's needs. Different users of the sofa usually have different heights, and when tall people use a fixed-height sofa, their legs are prone to curling up, which reduces the user's comfort and experience, thereby reducing the adjustability of the sofa.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] As attached Figure 1-6 As shown, the utility model provides an embodiment of a sofa with a liftable bottom, comprising a sofa body 1, a fixed frame 2 fixedly connected to the bottom of the sofa body 1, an outer frame 3 slidably connected to the outside of the fixed frame 2, an I-shaped frame 4 fixedly connected to the bottom of the sofa body 1 and the bottom of the outer frame 3, two fixed rods 5 fixedly connected to the rear of the I-shaped frame 4, a telescopic frame 6 hingedly connected to the inside of the two I-shaped frames 4, a plurality of sliding tubes 7 hingedly connected to the rear of the telescopic frame 6, the inner sliding of the sliding tube 7 is mounted on the outside of the fixed rod 5, and the middle of the bottom I-shaped frame 4 is fixed. A motor 8 is installed, and the output end of the motor 8 is fixedly connected to a screw 9. The external thread of the screw 9 is connected to a connecting rod 10. The two ends of the connecting rod 10 are fixedly connected to the middle of the two sliding tubes 7 at the bottom. Limiting grooves 11 are provided on both sides of the fixed frame 2. The internal sliding connection of the limiting groove 11 is limited. The bottom height of the sofa is conveniently lifted by the telescopic frame 6, which is conducive to adapting to users of different heights. The limiting block 12 slides inside the limiting groove 11 to improve stability during the raising process of the sofa.

[0032] As attached Figure 5 As shown, one side of the sofa body 1 is fixedly connected with a protrusion 13, the middle part of the protrusion 13 is rotatably connected with a screw rod 14, and one side of the protrusion 13 is rotatably connected with a table board 15. Two slide grooves 16 are provided at the bottom of the table board 15, and a plurality of threaded holes 17 are provided at the bottom of the table board 15. The external thread of the screw rod 14 is connected with a moving rod 18, and one side of the moving rod 18 is rotatably connected with two support rods 19. The other end of the support rod 19 is rotatably connected with a slider 20, and one side of the two sliders 20 is fixedly connected with a connecting plate 21, and a bolt 22 passes through the middle of the connecting plate 21. The cross-section of the slider 20 is set to be T-shaped. The table board 15 is convenient for users to place items that need to be placed at hand, and the support rod 19 is convenient for supporting the table board 15. The bolt 22 is convenient for fixing the two sliders 20 by screwing the bolt 22 into the corresponding threaded hole 17 after the connecting plate 21 is moved to an appropriate position, thereby fixing the support rod 19.

[0033] As attached Figure 1 As shown, one end of the screw rod 14 is fixedly connected to a knob 23 to facilitate the rotation of the screw rod 14.

[0034] As attached Figure 3As shown, one side of the two limiting blocks 12 is fixedly connected to both sides of the inner wall of the outer frame 3, so as to facilitate limiting when the fixed frame 2 slides inside the outer frame 3, thereby improving stability.

[0035] Working principle: When the bottom of the sofa needs to be lifted according to usage requirements, the motor 8 is first turned on so that the output end of the motor 8 drives the screw 9 to rotate. When the screw 9 rotates, the connecting rod 10 is driven to move from one end of the screw 9 to the other end. During the movement of the connecting rod 10, the telescopic frame 6 is driven to extend, so that the telescopic frame 6 drives multiple sliding tubes 7 to slide outside the fixed rod 5, thereby lifting the I-frame 4 on the top and driving the fixed frame 2 to slide inside the outer frame 3, which is conducive to lifting the sofa body 1 and is convenient for adjusting according to the height of different users. When the table top 15 needs to be used, the knob 23 is first turned so that the knob 23 drives the screw rod 14 to rotate When the screw rod 14 rotates, it drives the moving rod 18 to move from the top of the screw rod 14 to the bottom. When the moving rod 18 moves to the bottom end of the screw rod 14, it also drives one end of the two support rods 19 to move to the bottom end. When one end of the support rod 19 moves to the bottom end, it drives the other end of the support rod 19 to drive the slider 20 to slide from the left to the right inside the slide groove 16, and then the bolt 22 is passed through the middle of the connecting plate 21 and screwed into the corresponding threaded hole 17. By limiting and fixing the connecting plate 21, the positions of the two sliders 20 are limited and fixed. When the table top 15 is stored, the operation is reversed, which makes it convenient to place handy items when there is no coffee table around, thereby improving the convenience of using the sofa.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
