The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail:

To shown in Figure 7, a kind of bicycle saddle cushion locking mechanism comprises: a hollow seat bar 10 as Fig. 3; One socket block 20 is fixedly arranged on the top of hollow seat bar 10; One location fixture block 30 is attached on the socket block 20; One clamp 40 is arranged at the top of locating fixture block 30; One loam cake 50 is attached at the top of clamp 40; One rotating mechanism 60 is in order to be articulated a side of socket block 20 and loam cake 50; One screw-joining structure 70 is in order to the opposite side of locking or loosen socket block 20 and loam cake 50.

The lower end of socket block 20 is a fixed part 201, directly be fixedly arranged in the hollow seat bar 10, the upper end is an arc-shaped depression portion 202, and arc-shaped depression portion 202 is provided with several horizontal tooth bars, two side ends is provided with a longitudinal hole 203 and a projection 204, and projection 204 is provided with a cross through hole 205.

The bottom of location fixture block 30 is the arc 301 with several horizontal tooth bars, fits in the arc-shaped depression portion 202 of socket block 20, and its upper end respectively is provided with first pair of draw-in groove 302 and second pair of draw-in groove 303, for the two seat cushion bars (80,81) of location seat cushion.

The top of clamp 40 is the arc 401 with several horizontal tooth bars, be arranged at the top of location fixture block 30, the lower end of clamp 40 clamps this to seat cushion bar (80,81) locating respectively to be provided with first pair of draw-in groove 402 and second pair of draw-in groove 403 with respect to two pairs of draw-in grooves (302,303) of location fixture block 30 to cooperate this draw-in groove (302,303).

Loam cake 50, its bottom is provided with one and has the arc-shaped depression portion 501 of several horizontal tooth bars, fit in the top of clamp 40, the arc top of clamp 40 is built in this arc-shaped depression portion 501, two side ends is provided with a longitudinal hole 502 and two contact pin (503,504), two contact pin (503,504) a fixed space 505 is situated between between, insert pivot joint for the projection 204 on the socket block 20, this two contact pin (503,504) be respectively equipped with a through hole (506 on, 507), align each other with the cross through hole 205 on the projection 204 of socket block 20, cooperate rotating mechanism 60 to penetrate again, one side of loam cake 50 and belled body 20 is articulated, and loam cake 50 can be pivoted up and down, the longitudinal hole 502 of its opposite side aligns each other with the longitudinal hole 203 of socket block 20, the penetrating of screw rod 701 that cooperates screw-joining structure 70 again, screw rod 701 lower ends screw and are locked in nut 702, and then rotate its holding rod 703 to locking state, thereby make

loam cake
