Detailed ways

Below in conjunction with accompanying drawing, the present invention will be further described by specific embodiment:

See Fig. 1, Fig. 2, Fig. 3, a footrest for a seat, including a seat connecting rod 1, a fixed rod 2 connected to the seat connecting rod 1, a footrest connected to the fixed rod 2 The base 3, the limit lock 4 fixedly connected to the fixed rod 2 and the limit action mechanism 5 arranged on the footrest base 3, the seat connecting rod 1 is provided with a horizontal chute 11, and the two ends of the fixed rod 2 Slidingly connected in the horizontal chute 11, the seat connecting rod 1 can be connected to the bottom of the seat base, and the seat connecting rod 1 can be moved by setting the connecting slide rail, and the seat connecting rod 1 is also sleeved with a connecting rod length adjustment section 12. The two can slide relative to each other; both sides of the footrest base 3 are provided with a folded side stop 31 that is rotatably connected with the fixed rod 2, and the folded side stop 31 is provided with a guide groove 32 for the movement of the limit action mechanism; The footrest base 3 has a storage station between the seat connecting rods 1 and a use station extending from one end of the seat connecting rod 1. The storage station is usually folded under the seat bottom of the chair when it is idle. When the work position is to rest the feet, the footrest base 3 is stretched out of the seat bottom of the chair; the limit lock 4 is provided with a first locking notch 41 on one side and a second locking notch on the other side 42; the guide groove 32 and the limit action mechanism 5 cooperate with the first locking notch 41 to make the footrest base 3 in the storage position as shown in Figure 1, the guide groove 32 and the limit action mechanism 5 cooperate with the second lock notch 42 to make the footrest Foot base 3 is in use station as shown in Figure 2. The footrest base 3 includes a component installation front 33 and a component installation back 34 , the flip side stopper 31 is vertically folded toward the component installation back 34 , and the limit action mechanism 5 is arranged on the component installation back 34 .

The limit action mechanism 5 includes a limit rod 51 whose two ends are inserted into the guide groove 32, at least one pair of reset fixing pieces 52 arranged on the footrest base 3, and fixedly connected to the limit rod 51 and passing through the reset fixing piece. The tie rod 53 of 52. The limit action mechanism 5 also includes a return spring 54 sleeved on the pull rod 53 and located between the reset and fixed pieces 52. One end of the pull rod 53 is provided with a blocking portion 511 against the return spring 54, and the blocking portion 511 can be on the pull rod 53. A ring piece, the blocking part 511 is used to squeeze the return spring 54 after the limit rod 51 is pulled, and then the return spring 54 is stretched back to its position. The pull rod 53 is also connected with a pull handle 55 . The position of the limit rod 51 is adjusted by pulling the pull rod 53, and then the entire footrest 3 is driven to rotate in the circumferential direction. The limit lock 4 can be a sheet piece, which itself is welded and fixed on the fixed rod 2 . The limit lock 4 is also provided with one of the rotating arc surfaces 43 and two of the rotating arc surfaces 44 between the first locking notch 41 and the second locking notch 42 with the fixed rod 2 as the rotating shaft; The radius of one 43 and the second 44 of the arc of rotation relative to the fixed rod 2 is greater than the minimum radius of rotation of the guide groove 32 relative to the fixed rod 2 and less than the maximum radius of rotation of the guide groove 32 relative to the fixed rod 2, so that the design makes the limit The rod 51 can be stuck in the first locking notch 41 or the second locking notch 42, and by pulling the pull rod 53, the limit rod 51 can break away from the first locking notch 41 or the second locking notch 42 and move along the One of the arcs of rotation 43 or two of the arcs of rotation 44 are free to rotate in the circumferential direction. The first locking notch 41 is provided with a first horizontal blocking portion 411 and a first vertical blocking portion 412 for cooperating with the limit action mechanism 5 to prevent the rotation of the footrest base 3 , and the second locking notch 42 is provided for cooperating with the position limiting The action mechanism 5 prevents the second horizontal blocking portion 421 and the second vertical blocking portion 422 from rotating the footrest base 3 , and these blocking portions are used to block the limit rod 51 , thereby controlling the rotation of the footrest 3 . The first horizontal blocking portion 411 and the second horizontal blocking portion 421 are provided with anti-slip concave surfaces; the first horizontal blocking portion 411 and the second horizontal blocking portion 421 are provided with anti-slip blocking ends. These anti-slip designs prevent the use of the entire footrest 3 from being accidentally detached from the fixed state due to external force, and are convenient to realize manual control by manpower.
