DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The embodiment of the present application solves the problem of not taking the elderly and people with bad waist and legs into consideration by providing a seat frame for an elderly chair. When these people need to stand up from their seats, they cannot do so by relying on their own waist and legs and need external force or help from other people, which results in poor practicality. When the person using the chair needs to stand up, the cylinder 7 is started by pressing a button on the seat frame 1 to push the rotating seat 701 to move. The movement of the rotating seat 701 pushes the fixed frame 5 to rotate. The fixed frame 5 is limited by the rotation of the second rotating rod 8 and the first rotating rod 6. At this time, the rotation of the fixed frame 5 drives the seat frame 1 to rotate, so that the seat frame 1 is tilted, which makes it convenient for people to stand up and makes it effortless for the elderly to stand up. The chair is suitable for people with bad waist and legs who have difficulty standing up after sitting down.

[0024] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] The utility model embodiment discloses a seat frame of an elderly chair.

[0026] According to the attached Figure 1-4 As shown, it includes a seat frame 1, a seat cushion 2 is fixedly mounted on the seat frame 1, a fixing frame 5 is fixedly connected to the bottom of the seat frame 1, a bottom frame 4 is arranged directly below the fixing frame 5, and between the bottom frame 4 and the fixing frame 5 are arranged:

[0027] The adjusting unit includes a cylinder 7, a rotating seat 701 and a pushing rod 702. The cylinder 7 is rotatably connected to the base frame 4, and the pushing rod 702 is fixedly connected to the inner wall of the fixed frame 5. The output end of the cylinder 7 is connected to the rotating seat 701, and the rotating seat 701 is rotatably connected to the pushing rod 702. The adjusting unit is used to adjust the inclination angle of the fixed frame 5 and the seat frame 1. When the person using the seat needs to get up, the button on the seat frame 1 is used to start the cylinder 7 to push the rotating seat 701 to move. Under the movement of the rotating seat 701, the fixed frame 5 is pushed to rotate. Under the rotation of the second rotating rod 8 and the first rotating rod 6, the rotating path of the fixed frame 5 is limited. At this time, the rotation of the fixed frame 5 drives the seat frame 1 to rotate, so that the seat frame 1 is tilted, which is convenient for people to get up and stand, and makes it effortless for the elderly to get up. It is suitable for people with bad waist and legs who have difficulty standing up after sitting down.

[0028] The seat cushion 2 is rotatably connected with a footrest 201 and a backrest 202, which are driven to rotate by an electric telescopic rod. The footrest 201 is rotated to a suitable angle for placing legs, and the backrest 202 is rotated to a suitable angle for people to lie down.

[0029] A lumbar support pad 3 is placed on the seat cushion 2, and the lumbar support pad 3 is convenient for improving the comfort of people lying down.

[0030] A connecting seat 703 is fixedly connected to the top of the base frame 4 , and the cylinder 7 is rotatably connected to the connecting seat 703 . The rotation path of the cylinder 7 on the base frame 4 is limited, and the rotation of the cylinder 7 is related to the position of the push rod 702 .

[0031] The second rotating rod 8 is rotatably connected to the outer wall of the bottom frame 4 , and the second connecting rod 801 is rotatably connected to the inner wall of the second rotating rod 8 .

[0032] The second connecting rod 801 is fixedly connected to the fixing frame 5 , the second rotating rod 8 is rotationally connected to the fixing frame 5 via the second connecting rod 801 , the second rotating rod 8 is rotationally connected between the base frame 4 and the fixing frame 5 , and a rotation path is limited.

[0033] The top end surface of the bottom frame 4 is fixedly connected with a fixed seat 401 , the inner wall of the rotating seat 701 is rotatably connected with a first rotating rod 6 , and the inner wall of the first rotating rod 6 is rotatably connected with a first connecting rod 601 .

[0034] The first connecting rod 601 is fixedly connected to the fixing frame 5, the first rotating rod 6 is rotatably connected to the fixing frame 5 through the first connecting rod 601, the first rotating rod 6 is rotatably connected between the base frame 4 and the fixing frame 5, and the rotating path is limited;

[0035] When the fixing frame 5 rotates, the first rotating rod 6 and the second rotating rod 8 are driven to rotate simultaneously. Under the restriction of the first rotating rod 6 and the second rotating rod 8, the rotation path of the fixing frame 5 is limited;

[0036] Thus, when the cylinder 7 is driven to push the push rod 702 to move, the fixed frame 5 is pushed, driving the fixed frame 5 to rotate. At this time, under the action of the first rotating rod 6 and the second rotating rod 8, the fixed frame 5 moves along the specified path;

[0037] At this time, the fixing frame 5 moves up and rotates, driving the seat frame 1 to rotate, so that the seat frame 1 is tilted, which is convenient for people to stand up and makes it effortless for the elderly to stand up. It is suitable for people with bad waist and legs who have difficulty standing up after sitting down.

[0038] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
