Specific embodiment
With reference to the accompanying drawing, illustrate specific embodiment of the present utility model.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the simple electric bicycle front fork structure of the present embodiment, including standpipe
1, the bottom of standpipe 1 is equipped with lower linking plate 3 by limiting steering block 2, and the both ends of lower linking plate 3 are symmetrically installed with downwards front fork branch
Bar between two front fork struts and is located at the bottom of lower linking plate 3 and is provided with mud plate bracket 6;The structure of single front fork strut are as follows: packet
Aluminum barrel 8 is included, stepped hole is provided in the middle part of aluminum barrel 8, stepped hole is interior inserted with accurate handle pipe 5, and the top of accurate handle pipe 5 is equipped with silently
4, it silently 4 is connect with lower linking plate 3, passes through oil sealing 11 and dustproof cover 10 between 8 top inner wall face of aluminum barrel and accurate 5 outside wall surface of handle pipe
Connection, for accurate 5 bottom of handle pipe inside aluminum barrel 8 inserted with piston rod 18, the lower part of piston rod 18 is fixed by positioning seat 19
Position, bottom are locked by seabed screw 20, and 18 head outer ring of piston rod is cooperated by the inner wall of piston ring 12 and accurate handle pipe 5 and connected
