The specific embodiment

Below in conjunction with drawings and Examples the utility model is described in further detail.

As Fig. 1, shown in 2, a kind of bicycle damping frame, have fixed support and travel(l)ing rest, pipe 1 before fixed support includes at least, cant beam or camber beam 3, standpipe 4, middle shaft adapter 20 and axis Connection Block 19, the connection pipe 16-1 of the back chain stay 16 of support bracket fastened axis Connection Block 19 and travel(l)ing rest is by adapter shaft 18 is hinged down, the top of standpipe 4 is connected with preceding Connection Block 5, travel(l)ing rest by back vent connect standpipe 15 two ends respectively medially with the connection pipe 16-1 of back chain stay 16 affixed and with affixed the forming in rear stays 13 upper ends, and two lower ends of rear stays 13 are affixed with two back stays 14 of back chain stay 16 respectively; Connection Block 5 after being connected with on the back vent connection standpipe 15 ', between back Connection Block 5 and the preceding Connection Block 5 rear shock absorber is installed, and the preceding Connection Block 5 of an end of rear shock absorber and standpipe 4 is hinged, the back Connection Block 5 that the other end is connected with back vent on the standpipe 15 is hinged.

As shown in Figure 1, 2, rear stays 13 tops are connected with upright fork bridge sheet 12, and the tail end of the connection pipe 16-1 of back chain stay 16 is connected with mud plate connecting strap 17, all has mudwing connecting bore 22 on upright fork bridge sheet 12 and the mud plate connecting strap 17.Upright fork bridge sheet 12 and mud plate connecting strap 17 can be used to install mudwing, owing to have mudwing connecting bore 22 on upright fork bridge sheet 12 and the mud plate connecting strap 17, so install very convenient.

As shown in Figure 1, 2, rear shock absorber is by sleeve pipe 9, axle 10, spring 8, setting nut 7 and suspension 11 are formed, setting nut 7 is threaded with sleeve pipe 9, spring 8 is sleeved on the sleeve pipe 9, and between setting nut 7 and suspension 11, captive joint with suspension 11 in the lower end of axle 10, and stretch in sleeve pipe 9 upper end of axle 10.When rear shock absorber was installed, the upper end of sleeve pipe and preceding Connection Block 5 were hinged, the lower end of suspension 11 and back Connection Block 5 ' and hinged.

As shown in Figure 1, 2, shaft adapter 20 two ends formed during axis Connection Block 18 was fixed in by two connecting straps, and the front portion of back chain stay 16 connection pipe 16-1 has following connecting bushing 16-2, and following connecting bushing 16-2 is installed between two connecting straps of axis Connection Block 18.Connecting bushing 16-2 can protect down adapter shaft 18 under adopting, and avoids down adapter shaft 18 to expose outside, suffers dust, rain erosion, influences hinged performance.

As shown in Figure 2, the upper end of standpipe 4 is fixed with clamp 6, can be used to install seat cushion.Be connected with connecting strap 2 on the camber beam 3, can be used for installing the storage battery seat, be applicable to Electrical Bicycle.
