Detailed Description

The utility model is further illustrated by the following figures and examples, which are not intended to be limiting.

Examples. A modular sofa, constructed as shown in figures 1-3, comprising:

the sofa body 1 is internally provided with a placement cavity 2 at the front side, and a footstool 3 which can move relative to the sofa body 1 is arranged in the placement cavity 2;

The footstool 3 comprises a base 5 with casters 4, and a chair surface 6 which is controlled to rise and fall by a lifting mechanism is arranged on the base 5;

The lifting mechanism comprises guide rails 12 arranged on two sides of the interior of the footstool 3 and two sides of the lower end of the seat 6, a group of fixed blocks 13 and a group of movable blocks 14 capable of sliding relative to the guide rails 12 are arranged in the guide rails 12, X-shaped supporting legs 15 are arranged on the fixed blocks 13 and the movable blocks 14, the upper ends of the X-shaped supporting legs 15 are connected with the seat 6, and a height adjusting mechanism for adjusting the opening size of the lower ends of the X-shaped supporting legs 15 is arranged in the X-shaped supporting legs 15;

the first driving mechanism is used for driving the footstool 3 to move relative to the sofa body 1.

The driving mechanism comprises a first hinging seat 7 arranged at the innermost side of the arrangement cavity 2 and at the lower end of the two sides of the arrangement cavity 2, and a second hinging seat 10 arranged at the two sides of the footstool 3 and at the lower end of the footstool 3, wherein a mounting shaft 16 which is horizontally arranged and the end part of which penetrates through the sofa body 1 is arranged between the first hinging seats 7, a first rotating rod 8 which can rotate relative to the first hinging seat 7 is arranged on the mounting shaft 16, a second rotating rod 11 which can rotate relative to the second hinging seat 10 is arranged on the second hinging seat 10, the first rotating rod 8 is rotatably connected with the second rotating rod 11, and a rocking handle 17 which can drive the first rotating rod 8 to rotate is arranged at the end part of the first rotating rod 8.

The height adjusting mechanism comprises two groups of mounting plates 9 which are arranged between the X-shaped supporting legs 15 and horizontally arranged in parallel, the mounting plates 9 can rotate relative to the X-shaped supporting legs 15, screw holes are formed in the middle of the mounting plates 9, screw rods 19 which can rotate relative to the screw holes are arranged in the screw holes, telescopic sleeve rods 20 with two ends fixed on the mounting plates 9 are arranged outside the screw rods 19, and driving handles 21 are arranged at the end parts of the screw rods 19.

The screw 19 is provided with two groups of thread sections corresponding to the screw holes on the two groups of mounting plates 9, and the thread directions are opposite.

The utility model has the principle that when the sofa is used, the footstool 3 is generally received in the placement cavity 2 of the sofa body 1, which is beneficial to saving space, and when feet or legs are needed to be put on, the footstool 3 can be driven to move by the first driving mechanism, so that the sofa has better applicability and comfort. The first driving mechanism drives the first rotating rod 8 to rotate towards the footstool 3 through the rocking handle 17 and the mounting shaft 16, the mounting shaft 16 is fixedly connected with the first rotating rod 8 and can be connected in the forms of keys, welding and the like, when the first rotating rod 8 rotates, the second rotating rod 11 is driven to rotate, and as the height of the connecting point between the first rotating rod 8 and the second rotating rod 11 is continuously reduced, namely, the angle between the first rotating rod 8 and the second rotating rod 11 is continuously increased, the distance between the footstool 3 and the bottom of the placement cavity is also continuously increased, and the position of the footstool 3 is adjusted. Because friction exists between the footstool 3 and the ground, the footstool 3 is not easy to move when the legs and feet are placed on the footstool, the self-locking structure is not arranged, and furthermore, the two-way ratchet mechanism coaxially arranged on the mounting shaft 16 can be arranged to realize self-locking. Compared with a conventional footstool which is placed in the placement cavity 2 of the sofa body 1 and cannot be adjusted in height, the footstool 3 is more comfortable, and the legs are lifted by properly lifting the leg heights, so that the blood circulation of the legs can be promoted, and the symptoms of muscle tension, pain and the like of the legs can be relieved. And after the legs are lifted, the blood reflux can be promoted, the blood supply of the heart and the brain is increased, the situation of leg edema is relieved, and the benefit to the human body is relatively great. The lifting mechanism of the utility model utilizes the height adjusting mechanism to drive the opening sizes of the upper end and the lower end of the X-shaped supporting leg 15 to change, namely the fixed block 13 is fixed, the movable block 14 slides along the guide rail 12, so that the height of the chair surface 6 is changed, the principle is similar to that of the existing X-shaped lifting platform, but the existing X-shaped lifting platform usually adopts hydraulic equipment to realize height lifting adjustment, the footrest adopts the hydraulic equipment to realize relatively high cost, and has a certain potential safety hazard. Firstly, a group of rotating shafts are fixed on opposite sides of two groups of X-shaped brackets, the rotating shafts can adopt single-head bolts, a thread section is screwed into X-shaped supporting legs 15, then mounting plates 9 are fixed on the single-head bolt polished rod section, the mounting plates 9 can rotate relative to the rotating shafts, telescopic loop bars 20 are arranged between the mounting plates, screw holes are arranged in the mounting plates 9, screw rods 19 are arranged in the screw holes, the mounting plates 9 move in opposite directions or deviate from each other through the rotation of the screw rods 19, the adjustment of the height of a chair surface is realized, the arrangement of the telescopic loop bars can further ensure that the two groups of mounting plates 9 are kept horizontal and parallel, and the reliability is better. The utility model can easily realize the moving out or the retracting of the footstool, and the height of the footstool is adjustable, thereby having good comfort.
