Abstract

The utility model relates to a double-spring shock absorber for bicycle saddles, which is composed of main spring, a sleeve, a spring shaft and a spring base and an auxiliary spring. The main spring is arranged in an upright frame below a saddle tube and can be telescoped following the up/down slide of the saddle tube, and the sleeve is arranged and fixed at the outer side of the upright frame below the saddle. The spring shaft is sheathed in the sleeve, and the top end of the spring shaft is connected with the saddle through a connecting fork. The spring base is connected with the lower end of the spring shaft in a screwing mode and can be slid up and down in the sleeve following the spring shaft, and the bottom of the spring base is provided with a regulating sleeve. The auxiliary spring is sheathed on the spring shaft above the spring base arranged in the sleeve and can be telescoped following the slide of the spring base. The utility model has the advantages of simple structure and convenient assembly, and the double springs can effectively damp the up/down vibration of the saddle.

Description

Two-man act bicycle saddle bumper

The utility model relates to a kind of bicycle saddle shock absorption device, particularly relates to a kind of two-man act bicycle saddle bumper that comprises main spring and auxiliary spring.

When bicycle is ridden, to produce the vibrations of jolting inevitably on rugged road.Medium-to-high grade bicycles such as bicycle of the prior art, particularly mountain bike, its saddle is that direct mount is fixed in the bicycle stand, between and unnecessary shock absorption device.When riding jolting vibrations not only cause easily saddle damage, reduce its service life; but also may bicyclist's health be damaged; when particularly frequent or long distance is ridden; its nuisance vibration energy will be delivered to bicyclist's perineal position and be delivered to people's vertebra by perineal position by saddle, and vertebra, the cervical vertebra that makes human body is to cause head to come to harm.

The purpose of this utility model promptly is to provide a kind of bicycle saddle shock absorption device, makes it to slow down effectively the jolt vibrations of bicycle saddle in the process of riding, and then eliminates or alleviate bicycle nuisance vibration energy to the injury of human body with to the damage of saddle.

To achieve these goals, the utility model is nested with Seat pillar of bicycle in the bicycle stand and utilizes major and minor two springs to constitute a kind of two-man act bicycle saddle bumper.Main spring directly is sleeved in the stand of seatpillar below, and can be with seatpillar sliding up and down and flexible in stand, and auxiliary spring then is installed in the outside of stand by sleeve, spring axle and spring abutment, and can with seatpillar slide up and down and flexible.

So in the two-man act bicycle saddle bumper that constitutes, main spring and auxiliary spring replenish mutually, the vibrations of jolting that can slow down bicycle saddle effectively, thereby eliminate or alleviation bicycle nuisance vibration energy to the injury of human body with to the damage of saddle.Be described in further detail below in conjunction with the technical characterictic of specific embodiment the utility model two-man act bicycle saddle bumper.

Fig. 1 is the structural representation of the utility model two-man act bicycle saddle bumper.

With reference to the accompanying drawings 1, the utility model two-man act bicycle saddle bumper mainly is made of main spring and sleeve, spring axle, spring abutment and auxiliary spring.

Main spring 1 is a stage clip, be directly installed in the stand 3 of seatpillar 2 belows and can with seatpillar 2 in stand 3 slide up and down and flexible.Sleeve 4 is the cylindrical shape of lower ending opening, is fixed on stand 3 outsides of saddle (not marking among the figure) below, and its top is provided with the axis hole that is used for the install spring axle.Spring axle 5 is a circular shaft, the shaft hole sleeve that passes sleeve 4 tops is contained in the sleeve 4, its top links to each other with saddle (not marking among the figure) by shaft clevis 6 and can sliding up and down and move up and down with seatpillar 2, its lower end is provided with the screw thread of working in coordination with spring abutment, spring abutment 7 is cylindrical, also can slide up and down in sleeve 4 with spring axle 5 by the lower end of central screwhole spiro bonding in spring axle 5, its bottom is installed with the adjustment cover 8 that is used to adjust its position, and its side also is provided with fixing screw 9.Auxiliary spring 10 is a stage clip, be sleeved on the spring axle 5 of spring abutment 7 tops in the sleeve 4 and can with spring abutment 7 slide up and down and flexible.

By the structure of the above two-man act bicycle saddle bumper as can be known, but the vibration of main spring 1 and auxiliary spring 10 effective damping saddles, alleviate or the nuisance vibration energy when eliminating cycling to the injury of human body with to the damage of saddle.Therefore, the utility model is particularly suitable for the shock absorption device as bicycle saddle.
