Abstract

The utility model relates to a vibration absorber of a bicycle saddle, which is arranged between a bicycle frame vertical tube and a saddle tube and is characterized in that a pin 1 is arranged in the middle part of the bicycle frame vertical tube, a pin 3 is arranged in the middle part of the saddle tube, and a vibration absorbing spring 2 is arranged between two pins in the tube; a partition sleeve 4 is arranged in the middle of the connecting bolts of a shelf and the bicycle frame to ensure a clearance between the bicycle frame vertical tube and the saddle tube for the saddle tube to be telescopic up and down easily and to limit the saddle tube from swinging side to side. The height of the saddle tube is controlled by the position of the pin 3.

Description

The bicycle saddle shock absorption device

The utility model belongs to a kind of shock absorption device in the bicycle shock mitigation system.

Present bicycle structurally all changes on the appearance and modeling, also exists some shortcomings on Practical Performance.For example: bicycle saddle changes not quite decades, and harder saddle only leans on several extension springs and two very short stage clip dampings, poor effect.Make the cyclist very uncomfortable, run into uneven road surface cyclist the more severe of ripple of running.

The purpose of this utility model provides a kind of bicycle saddle shock absorption device.This device is that a kind of manufacturing is simple, installs easily, and easy to use, cost is low, the shock absorption device that the people that repairs just can install.

The purpose of this utility model is achieved in that at through hole of cycle frame standpipe drilled in middle, load onto a pin 1, through hole of saddle pipe drilled in middle, adorn a pin 3, damping spring 2 is contained between two pins, and just damping spring 2 tops are contained in the saddle pipe.Seat tube upper end rear side is opened a guide groove 5, and the pin 3 on the saddle pipe is contained in the guide groove 5.Adorn a spacer 4 in the middle of the attachment bolt of vehicle frame and shelf.

Further specify below in conjunction with accompanying drawing:

Fig. 1: expression bicycle saddle shock absorption device front view

Fig. 2: expression bicycle saddle shock absorption device is to view

In Fig. 1, the pin 1 on the seat tube can be riveted, but also bolt together; The diameter of damping spring 2 must guarantee spring normally compression in saddle pipe less than the saddle pipe internal diameter; Pin 3 one ends at saddle pipe middle part are not exceed the saddle pipe external diameter, guarantee saddle pipe stretching up and down in seat tube; The other end exceeds saddle pipe 2-3 millimeter, has promptly played positioning action, has controlled swinging of saddle again.Pin 3 welds with saddle pipe.

In Fig. 2, the length that the guide groove 5 of seat tube upper end rear side will be opened is a little, guarantee the flexible up and down distance of saddle pipe, width is greater than pin 0.5-0.8 millimeter, little clearance has promptly guaranteed flexible freedom, controlled again and swing, and people's deviation in the thigh motion to pedal the time has just in time been satisfied in a small amount of swing, makes more favourable to pedal.Spacer 4 is contained in the middle of vehicle frame and the shelf connected nut, has controlled the gap of seat tube and saddle pipe, has further guaranteed the flexible up and down of saddle pipe, has also controlled saddle pipe and has upwards gone here and there out.

The utility model can be installed when new car dispatches from the factory, and according to human body height difference, can be installed in different positions to the pin on the saddle pipe 3, guarantees height by bike.Select for use when supplying to purchase car.The utility model also can be installed on the old bike, and the people that repairs can install.

The applicant thinks that the utility model cost low (only using several yuans) just can change cyclist's traveling comfort, is a kind of simple shock absorption device really.The applicant does overtesting on many people's bicycle, effect is fine, receives an acclaim.Realize that best way of the present utility model is by convention of international trade, the Bicycle Plant in the whole nation all produces the bicycle that has shock absorption device.

Claims

1, a kind of bicycle saddle shock absorption device, its principal character is: a pin respectively is equipped with at seat tube middle part and saddle pipe middle part, and damping spring is loaded between two pins; Its top is contained in the saddle pipe; Seat tube upper end rear side has a guide groove; Adorn a spacer in the middle of the tie bolt of vehicle frame and shelf.

2, saddle shock absorption device according to claim 1 is characterized in that pin one end on the saddle pipe is consistent with the saddle pipe external diameter, and the other end exposes certain-length in guide groove.
