TECHNICAL FIELD
[0001] The application relates to the technical field of sofas, in particular to an anti-static zero-gravity sitting-feeling sofa. BACKGROUND
[0002] The zero-gravity sofa is a special sofa, which adjusts the position of the back and legs of a human body so that the knees and the heart of the human body are on the same horizontal line, thereby achieving a weightless state. When adjusting, the zero-gravity sofa usually rotates the backrest downward and rotates the leg rest upward, thereby adjusting the position of the back and legs of the human body.
[0003] However, in the process of rotating the backrest downward, the upper end of the backrest moves away from the sofa itself, so that when the sofa is placed, a space for the movement of the backrest needs to be left between the sofa and the wall, thereby easily causing the waste of space.
[0004] Therefore, a new technical scheme needs to be proposed to solve the above problems. CONTENT OF THE UTILITY MODEL

DETAILED DESCRIPTION
[0031] The application will be further described in detail below with reference to the accompanying drawings.
[0032] The anti-static zero-gravity sofa disclosed in the application, as shown in Figure 1 and Figure 2 , comprises a base 1 placed on the ground, a sliding seat 11 slidingly arranged on the base 1, a driving piece 12 for pushing the sliding seat 11 to move back and forth, a seat 2 arranged on the sliding seat 11, and a guide piece 3 for limiting the rotation angle of the seat 2. The sliding seat 11 is a rectangular frame structure, and is connected with the base 1 through guide rails and sliding blocks and slides on the upper surface of the base 1. The driving piece 12 is an electric push cylinder in this embodiment, and is arranged below the sliding seat 11. One end of the driving piece 12 is rotationally connected with the upper end surface of the base 1, and the other end of the driving piece 12 is hingedly connected with the end of the sliding seat 11 away from the driving piece 12. The seat 2 comprises a seat cushion 21 arranged horizontally, a backrest 22 arranged at one end of the seat cushion 21, and a leg support 23 arranged at the other end of the seat cushion 21. The backrest 22 is arranged above the seat cushion 21, and the leg support 23 is arranged below the backrest 22. The surfaces of the seat cushion 21, the backrest 22 and the leg support 23 are all covered with an anti-static fabric. The anti-static fabric in this embodiment is made of pure cotton and conductive fibers. The connection between the seat cushion 21 and the backrest 22 is close to the driving piece 12 and is rotationally connected above the sliding seat 11. The guide piece 3 comprises a fixed rod 31 fixedly installed on the base 1 and a movable rod 32 slidingly arranged on the fixed rod 31. The end of the movable rod 32 away from the fixed rod 31 is rotationally connected with the upper end of the side wall of the backrest 22 away from the seat cushion 21. The end of the fixed rod 31 away from the base 1 is inclined towards the seat cushion 21. When the driving piece 12 pushes the sliding seat 11 to move in the direction away from the driving piece 12, the upper end position of the backrest 22 is not easy to move horizontally, so that the whole seat 2 is rotated. When the seat 2 is rotated, the backrest 22 will not move towards the wall, so that the sofa can be directly leaned against the wall.
[0033] In order to avoid too much space between the backrest 22 and the wall when the seat 2 is not moved, a containing groove 221 is formed on the side wall of the backrest 22 close to the guide 3, the containing groove 221 penetrates the lower end surface of the backrest 22, and the guide 3 can be embedded in the containing groove 221, so that the backrest 22 can be closer to the wall and the space between the backrest 22 and the wall can be reduced when the seat 2 is not rotated.
[0034] As shown in Figure 3 the leg rest 23 is rotatably connected with the seat cushion 21, and the leg rest 23 and the seat cushion 21 are provided with a limiting assembly 4 for limiting the position of the leg rest 23. The limiting assembly 4 comprises a limiting plate 41 fixed below the seat cushion 21, a limiting piece 42 rotatably connected with the leg rest 23 close to the side wall of the base 1, and an elastic piece 43 for driving the limiting piece 42 to rotate towards the limiting plate 41. The limiting plate 41 is arranged parallel to the sliding direction of the sliding seat 11, and a plurality of limiting grooves 411 are formed on the lower end surface of the limiting plate 41 and penetrate the two side walls of the limiting plate 41 parallel to the length direction of the limiting plate 41. The inner walls of the limiting grooves 411 close to the leg rest 23 are provided with guide inclined surfaces 412, and the guide inclined surfaces 412 are inclined towards the leg rest 23 close to the lower end openings of the limiting grooves 411. The limiting piece 42 is in the shape of a rectangular frame, one end of the limiting piece 42 is rotatably connected with the leg rest 23, and the other end of the limiting piece 42 can be embedded in the limiting groove 411, so as to limit the relative position between the leg rest 23 and the seat cushion 21.
[0035] The leg rest 23 is provided with a pulling rod 5 close to the base 1, the sliding direction of the pulling rod 5 is perpendicular to the sliding direction of the sliding seat 11, one end of the pulling rod 5 close to the seat cushion 21 is rotatably connected with a connecting rod 51, the other end of the limiting piece 42 close to the leg rest 23 is fixed with an extension block 421, and the other end of the connecting rod 51 away from the pulling rod 5 is rotatably connected with the extension block 421. The elastic piece 43 is a spring in this embodiment, the elastic piece 43 is sleeved on the pulling rod 5, one end of the elastic piece 43 away from the seat cushion 21 is in abutment with the leg rest 23, and the other end of the elastic piece 43 is in abutment with the pulling rod 5, so as to drive the pulling rod 5 to move towards the seat cushion 21, and drive the connecting rod 51 to move the limiting piece 42 towards the limiting groove 411 and abut in the limiting groove 411.
[0036] As shown in Figure 2As shown, the end of the pulling rod 5 away from the cushion 21 is also provided with a handle 52, which is arranged close to the lower end of the leg rest 23 and on the side wall of the leg rest 23 close to the base 1. When the position of the leg rest 23 needs to be adjusted, pulling the handle 52 can drive the pulling rod 5 to move, so that the limiting piece 42 is separated from the limiting groove 411, thereby adjusting the position of the leg rest 23.
[0037] As shown in the drawings, Figure 4 As shown, the end face of the base 1 close to the leg rest 23 is also provided with a receiving groove 13, and the drawer 14 is slidably arranged in the receiving groove 13. The two side walls of the drawer 14 parallel to the sliding direction are both provided with an opening communicating with the inner cavity of the drawer 14. Therefore, when the drawer 14 is pulled out of the receiving groove 13, the articles can be directly taken out from the two sides of the drawer 14, and the position of the drawer 14 cannot be directly seen after the leg rest 23 is closed, so that the placement of valuable articles is safer.
[0038] The implementation principle of the embodiment is that when the seat 2 needs to be rotated, the driving piece 12 drives the sliding seat 11 to move, and the position of the upper end of the backrest 22 is limited, so that the entire seat 2 is rotated. When the leg rest 23 needs to be rotated away from the base 1, the leg rest 23 can be directly rotated. When the leg rest 23 needs to be moved towards the base 1, the pulling rod 5 can be pulled, so that the limiting piece 42 is separated from the limiting groove 411, and then the position of the leg rest 23 is adjusted. When the articles in the drawer 14 need to be taken out, a downward force is applied to the handle 52 to drive the limiting piece 42 to be separated from the limiting groove 411, and then the leg rest 23 is rotated upward to the limit position, and then the drawer 14 is pulled out of the receiving groove 13 to take out the articles.
[0039] The embodiments of the specific embodiment are the preferred embodiments of the application, but do not limit the protection scope of the application. Therefore, any equivalent changes made according to the structure, shape, principle of the application should be covered within the protection scope of the application.
