DETAILED DESCRIPTION

The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

As shown in FIGS. 1 to 5 , an adjustable multifunctional sofa comprises a support plate 1, a support leg 2 is arranged on the bottom surface of the support plate 1 to support and fix the sofa, the support leg 2 is arranged to support a fixing rod 201 on the bottom surface of the support plate 1, and a connecting rod 202 is arranged between the two fixing rods 201 to connect the two to improve the supporting effect, a groove 203 arranged on the bottom surface of the fixing rod 201 is supported on the ground through a bottom plate 204, a cushion 3 arranged on the surface of the support plate 1 is connected to a buffer component 4 through a fixing plate 301, and the buffer component 4 is provided with a fixing frame 40 The connecting slide bar 402 cushions the seat cushion 3 on the surface of the fixed plate 301, the handles 5 fixedly connected to the two sides of the support plate 1 support the user's arms through the soft cushions 501, and the inner side of the fixed cylinder 6 fixedly connected to one end of the support plate 1 is provided with an adjustment component 7, and the adjustment component 7 is provided with a stepping motor 701 to drive the driving rod 702 to rotate, so that the special-shaped tooth block 703 on the surface of the driving rod 702 can drive the rotating rod 708 to adjust the angle through the gear 705, and the supporting angle of the backrest cushion 8 is adjusted through the adjustment plate 709 on the surface of the rotating rod 708.

An adjustment hole 205 is set on the inner side of the groove 203 to fix the position of the fixed rod 201 through a shift rod 206. A stopper 207 is set on the surface of the shift rod 206 to slide on the inner side of the fixed rod 201. The position of the shift rod 206 is adjusted by a spring 208, and the shift rod 206 can slide in a straight groove 209 fixed on the surface of the groove 203.

Through the above technical solution, under the action of the spring 208, the shift rod 206 can be extended and retracted inside the fixed rod 201, thereby ensuring that one end of the shift rod 206 can be clamped inside the adjustment hole 205, adjusting the height of the fixed rod 201, and allowing the length of the supporting leg 2 to be adjusted arbitrarily to ensure the levelness of the sofa.

Damping members 403 fixed to the inner side of the fixing frame 401 are provided at the upper and lower ends of the sliding rod 402 .

Through the above technical solution, under the action of the damping member 403, it is ensured that the sliding rod 402 can provide obstruction to the upper fixing plate 301 during the sliding process inside the fixing frame 401, thereby ensuring the comfort of the seat cushion 3.

The stepping motor 701 fixedly connected to one end of the inner side of the fixing cylinder 6 is controlled by a control board 710 fixed on the surface thereof.

Through the above technical solution, by controlling the control panel 710 located outside the fixed cylinder 6, the stepper motor 701 can be used as a driving member of the adjustment component 7 to drive the adjustment component 7 to adjust the angle of the backrest cushion 8.

Limiting blocks 704 are provided at both ends of the special-shaped tooth block 703 to limit the position of the gear 705, so that the gear 705 can move under the limit of the adjusting member 707 through the fixing blocks 706 on the surface during the circular rotation.

Through the above technical solution, under the adjustment limit of the adjustment member 707, it is ensured that the gear 705 can rotate around the special-shaped tooth block 703, so as to adjust the support angle of the adjustment plate 709 on the surface of the rotating rod 708 inside the gear 705.

When in use, when the user uses the adjustable multifunctional sofa, the sofa is moved to the desired position. According to the inclination of the ground, the shift rod 206 is moved. Under the elastic force of the spring 208, one end of the shift rod 206 can be separated from the adjustment hole 205, so that the shift rod 206 can slide inside the straight groove 209, and the length of the support leg 2 is adjusted to ensure that the four support legs 2 can be supported on the ground with different flatness, so as to ensure the levelness of the sofa. When the user sits on the sofa, the downward pressure of the cushion 3 can make the fixing plate 301 pass through the fixing plate 301. The sliding rod 402 slides on the inner side of the fixed frame 401, and with the assistance of the damping member 403, the pressure on the seat cushion 3 is relieved. When adjusting the support angle of the backrest cushion 8, the button on the surface of the control panel 710 is pressed, and the driving rod 702 is driven to rotate by the stepper motor 701, so that the special-shaped tooth block 703 on the surface of the driving rod 702 is limited by the limit block 704, and the driving gear 705 rotates around the special-shaped tooth block 703, so that the rotating rod 708 on the inner side of the gear 705 can drive the backrest cushion 8 on the surface of the adjustment plate 709 to change the support angle.
