Embodiment 1
[0034] see Figure 1-Figure 3 , two-way torsional swing butterfly seat, including a rotating shaft 7, the rotating shaft 7 is a hollow circular tubular structure, a pair of vertically arranged seat bows 5 are fixed on the bottom of the rotating shaft 7, and the seat bows 5 can cooperate with seat cushion fixing fixtures commonly used in the prior art, Thus, the entire saddle is fixed on the seat post, and the seat post is fixed in the seat tube of the bicycle through the seat tube clamp; the side shaft 8 is arranged on one side of the middle position of the rotating shaft 7, and the two seat bows 5 are symmetrically arranged on both sides of the side shaft 8, The side shaft 8 is a cylindrical structure arranged radially along the rotating shaft 7 , and the axial direction of the side shaft 8 forms an acute angle with the horizontal plane where the axis of the rotating shaft 7 is located.
[0035] A pair of rotating drums 3 are sleeved on the rotating shaft 7. The rotating drum...
Embodiment 2
[0040] see Figure 4 and Figure 5 , two-way torsion butterfly seat, the only difference from Embodiment 1 is that the reversing device includes a side shaft 8 arranged radially along the shaft 7 on one side of the shaft 7, the side shaft 8 is arranged between the two rotating cylinders 3, and the side shaft 8 One end away from the rotating shaft 7 is connected with a transmission rod 14 in rotation, and the transmission rod 14 is vertically arranged with the side shaft 8; the transmission rod 14 is a cylindrical rod whose axis is perpendicular to the axis of the side shaft 8, and the transmission rod 14 is sleeved with a sleeve 12; The middle position of the transmission rod 14 is provided with a through hole arranged radially along the transmission rod 14 and matched with the side shaft 8. The side shaft 8 is set through the transmission rod 14, and the side shaft 8 is also provided with a limiter for the transmission rod 14 to move along the side shaft 8. A limit mechanism...
Embodiment 3
[0043] see Figure 6-Figure 8 , two-way torsion butterfly seat, the only difference from Embodiment 1 is that the turntable 4 is a fan-shaped plate structure, the axis of the turntable 4 and the axis of the turntable 7 are coaxially arranged, and the outer ring of the turntable 4 is evenly distributed with a plurality of first engagement columns 10, The first engaging column 10 is arranged radially along the turntable 4; the reversing disc 6 is a circular plate-shaped mechanism coaxially arranged with the side shaft 8, and the outer ring of the reversing disc 6 is evenly distributed with the first engaging column 10. Two engagement columns 11, the second engagement column 11 is arranged radially along the reversing disc 6; the first engagement column 10 and the second engagement column 11 are both cylindrical structures.
