Abstract
The utility model relates to a bicycle damping device which is arranged in the B pipe of the bicycle frame of the bicycle and is composed of a lifting guiding pipe, a lifting pipe, a spring, regulating screws and regulating nuts. The utility model is characterized in that the lifting guiding pipe is arranged in the B pipe of the bicycle frame, the regulating screws and the regulating nuts are arranged in the pipe at the bottom end of the lifting guiding pipe, a damping spring is arranged on the lifting guiding pipe, the lifting pipe is arranged at the upper part of the spring, and the outward extending pipe end of the lifting pipe is connected with a seat pad. The seat pad is in elastic connection with the bicycle frame through the structure, so the seat pad can automatically flex up and down with the irregular change of the road surface for damping in the running course of the bicycle; the utility model has the advantages of simple structure, reasonable design and low manufacture cost, and can be widely used in various kinds of bicycles.
Description
The utility model relates to a kind of bicycle shock absorption device.
At present, the shock absorption device of bicycle realizes that by divide into one group of spring at the car cushion damping rate of this shock absorption device is very little, and only suitable bicycle drives at moderate speed on the flat road of light.Another kind of shock absorption device is to establish a spring damper on the seat thick stick outside, though the damping effect of this shock absorption device is good, has defective on its structure design.
The purpose of this utility model is: provide a kind of reasonable in design, the bicycle shock absorption device that damping effect is good.
The bicycle shock absorption device is made up of lifting catheter, fall way, spring, governing screw and setting nut, it is characterized in that: lifting catheter is located in the vehicle frame b pipe, and the bottom pipe of lifting catheter is provided with a coaxial governing screw, is furnished with setting nut on it; Setting nut top is provided with a spring, and fall way is located at spring top, and the overhanging end of fall way is connected with seat cushion.Fall way is provided with the axial location groove, and locating dowel pin is located at the top of lifting catheter, and joins platform with positioning groove.
The utlity model has the advantage of following two aspects:
One, simple in structure, reasonable in design, low cost of manufacture can be widely used in various types of bicycles.
The predetermincd tension of two, the good reliability of this shock absorption device, and damping spring can be regulated according to cyclist's body weight, has good damping effect.
Description of drawings:
Fig. 1 is the utility model body frame structure for automotive scheme drawing,
Fig. 2 is the enlarged drawing at I place among Fig. 1,
Fig. 3 is the detail drawing of fall way.
Below in conjunction with drawings and Examples the utility model is described further.
As shown in Figure 1 and Figure 2, shock absorption device of the present utility model is installed in the cycle frame b pipe 5, and this shock absorption device is made up of lifting catheter 4, fall way 3, spring 7, governing screw 9 and setting nut 8.Lifting catheter 4 is installed in the vehicle frame b pipe 5, by a spacers one coaxial governing screw 9 is arranged in the lower end pipe of lifting catheter 4, be furnished with setting nut 8 on it, damping spring 7 is installed on setting nut 8 tops, fall way 3 is contained in spring 7 tops, between spring 7 and fall way 3 pad 6 is housed.Have the axial location groove on the fall way 3, locating dowel pin 2 passes the top that positioning groove is fixed on lifting catheter 4, and the pipe end of lifting catheter 4 has sidewindered outside thread outward, and clamping nut 1 is housed on it.
Fall way 3 can slide up and down along lifting catheter 4 by positioning groove on it.The unloaded compressive force of spring 7 can be regulated by setting nut 8.
The said structure design makes between seat cushion and the vehicle frame and has realized resilient connection.Bicycle in the process of moving, its seat cushion can be with the rugged variation in road surface freely flexible up and down, reach the purpose of damping.
