Description
Technical field
The utility model is related to a kind of bicycle shock absorbers, are suitable for the damping of modern bicycle and other dampings
Purposes.
Background technology
Currently, the damper of existing bicycle is largely spring shock absorption.Although spring shock absorption can reduce bicycle
Vibrations make spring-compressed have the function that damping by what pressure was added in both ends of the spring, but spring is easy to fail, spring
Damping effect it is not apparent enough, be now badly in need of a kind of device of significantly damping, after adding pressure up and down, above and below the system of damping
The larger device that more comfortable damping experience can be generated to loading of amplitude.Overcome current damping effect is bad to be stranded
It is difficult.
Invention content
The utility model provides a kind of bicycle damper, is a kind of reasonable for structure, device of good damping effect.
The utility model includes top shell, and the interior nested encryptions mobile rack by sliding slot and locating piece of shell is mobile
It is provided with below rack on car axle hole centre and is provided with locating piece, gear hole is provided among the shell, gear hole is embedded with cylinder
Gear, the mobile rack are intermeshed with roller gear, and the roller gear both ends are equipped with jackshaft, and jackshaft is provided with installation
The jackshaft in hole, the both ends stretches out shell by gear hole, and the spiral of some strength is equipped on the jackshaft at the both ends
Shape clockwork spring, centre and the mounting hole of spiral shape clockwork spring embed connection, the raised pin on the other end and shell of spiral shape clockwork spring
Connection.
Be equipped among the spiral shape clockwork spring as needed circular columns be embedded in the mounting hole of roller gear realize and
The mutual movement of roller gear, damping reasonable for structure are reliable.

Specific implementation mode：
Specific embodiment below, utility model further elucidated above.
The utility model includes top shell 1, the interior nested encryptions mobile rack by sliding slot 11 and locating piece 22 of shell 1
2, the lower section of mobile rack 2, which is provided on 21 centre of car axle hole, is provided with locating piece 31, and gear hole 12, tooth are provided among the shell 1
Wheel bore 12 is embedded with roller gear 4, and the mobile rack 2 is intermeshed with roller gear 4, and 4 both ends of the roller gear are equipped with
Jackshaft, jackshaft are provided with mounting hole 41, and the jackshaft at the both ends stretches out shell 1 by gear hole 12, in the both ends
The spiral shape clockwork spring 3 of some strength, centre and the embedded connection of mounting hole 41, the spiral shape of spiral shape clockwork spring 3 are installed on countershaft
The other end of clockwork spring 3 is connect with the raised pin 13 on shell 1.
When the damper work of bicycle, the heavy burden end of 1 top connection bicycle of shell, the car axle hole 21 of mobile rack 2
The axle of bicycle is connected, when cycling moves, shell 1 and mobile rack 2 move toward one another, and mobile rack 2 passes through gear
The rotation of roller gear 4 inside the engagement drive of rack, roller gear 4 drive clockwork spring 3.Clockwork spring 3 is tightened up curling and becomes at this time
Small, gear generates axial moment of resistance, and to the elastic force for keeping the generation of clockwork spring 3 and shell 1 opposite, clockwork spring 3 and shell 1 are opposite
The distance of movement is bigger, on the moment of resistance that clockwork spring 3 crimps bigger generation is bigger, and bicycle generates during movement is jolted
Under different power size, offseted with the crimp force of clockwork spring 3, to realize the function of damping.
