Detailed Description
The present invention is described in detail below with reference to the attached drawings.
As shown in fig. 1-3, the leg rest stretching structure of the learning chair comprises a seat cushion 1 and a backrest structure arranged at one end of the seat cushion 1, wherein the bottom of the seat cushion 1 is provided with a leg rest structure 10, and the leg rest structure 10 is matched with the backrest structure capable of adjusting the inclination angle, so that students can relax the back and legs and obtain a better sleeping posture when having a rest, thereby effectively relieving fatigue; in order to make leg hold in palm structure 10 can adapt to more crowds better, leg holds in palm structure 10 and includes the fixing base 2 that sets up along 1 length direction of cushion, can be to the flexible ground that slides of front end install actuating lever 21 in the fixing base 2, actuating lever 21 end shaping has the level to the connecting block 22 of both sides extension, connecting block 22 horizontal shaping has the connecting hole 23 that runs through, it has dwang 24 to alternate through connecting hole 23 level on the connecting block 22, the leg layer board 3 that can overturn is installed respectively to the naked part in dwang 24 both ends, when supporting, leg layer board 3 can receive great gravity, consequently, adopt connecting block 22 to be used for improving the rotational stability and the support intensity of dwang 24, furthermore, the length that its stretches out can be adjusted to leg layer board 3 that has extending structure, can adapt to the crowd of different heights.
More specifically: leg layer board 3 is including the even shaping has the board body 31 of a plurality of bleeder vents 32, and the arch supporting part 37 that is used for supporting the shank is upwards protruding slightly in the middle part of the board body 31 middle part, and this body 31 edge of board is provided with the frame 33 that encloses that is used for the design along a week, and the leg layer board 3 of design like this can be better accords with the ergonomic design, when supporting the shank, can laminate the shank well.
