Abstract
The utility model relates to a damper used for a bicycle, comprising a damping rod body, and a damping housing with one opening end, one end of the damping rod body is disposed in the damping housing, a damping spring is disposed in the damping housing and between the damping rod body and the damping housing, the opening end of the damping housing is provided with a blocking nut, the central part of the inner wall of the damping housing is fixedly provided with a limiting loop, the damping rod body is provided with a limiting block, the damping spring comprises a first damping spring disposed on the damping rod body and between the limiting loop and the limiting block, a second damping spring disposed between the bottom end surface of the damping rod body and the bottom of the damping housing, and a damping assistant sealing device. The damper used for a bicycle is advantaged by simple structure, convenient use, good damping effect, and long service lifetime.
Description
Technical field
The utility model relates to a kind of vibration damper, is specifically related to a kind of bicycle use vibration damper.
Background technique
The vibration damper of existing vehicle such as bicycle use adopts spring hydraulic type vibration damper usually, and spring hydraulic type vibration damper combines spring shock absorption and two kinds of damping modes of hydraulic damping damping, and its shock-damping structure mainly is made of damping spring and damper.General vibration damper by a damping shell and the tubular shape damping body of rod and be arranged on the damping shell and the tubular shape king-rod between damping spring constitute.Vibration damper is after using a period of time; regular meeting's appearance causes the damage of damping spring greatly easily because of wearing and tearing; influence the shock-absorbing function of vibration damper; if untimely discovery is easy to cause the damage of whole vibration damper; and it is stressed when excessive at vibration damper; the damping body of rod is easy to swing in the damping shell, not only influences its damping effect and working life, and influences that it is attractive in appearance.
Summary of the invention
At the problems referred to above, the purpose of this utility model provides a kind of bicycle use vibration damper, and it has abrasion-proof structure, can guarantee that the damping body of rod can not swing in the damping shell, guarantees its shock-absorbing function.
The technological scheme that realizes the utility model purpose is as follows:
A kind of bicycle use vibration damper, comprise the damping body of rod, the damping shell of one end opening, the damping body of rod one end is arranged in the damping shell, between the damping shell internal damping body of rod and damping shell, be provided with damping spring, the opening end of damping housing is provided with locking nut, damping inner walls middle part is set with position limit cycle, the damping body of rod is provided with limiting stopper, described damping spring comprises and is arranged on position limit cycle, first damping spring between the limiting stopper on the damping body of rod, and be arranged on second damping spring between damping body of rod bottom end and the damping housing bottom, also comprise the damping auxiliary sealing device.
Described damping auxiliary sealing device comprises and is arranged on the damping auxiliary sleeve on the damping body of rod between limiting stopper and the locking nut.The damping auxiliary sleeve can guarantee that the damping body of rod can not swing in the damping housing, guarantee the giving full play to of shock-absorbing function of vibration damper.
Also comprise two stuffing box glands that are separately positioned on the auxiliary sleeve upper and lower.Two stuffing box glands guarantee that the Lubricants between the two can not leak, and can also play preventing that dust impurity from entering between the two in addition, and the function that influences the damping auxiliary sleeve is normally brought into play.
Adopt such scheme, be arranged on first damping spring on the damping body of rod between position limit cycle, the limiting stopper, and be arranged on second damping spring between damping body of rod bottom end and the damping housing bottom, can produce the function of damping simultaneously, improved the damping effect of vibration damper, when one of them damaged when two damping springs simultaneously, another damping spring can also continue to use.The damping auxiliary sleeve on the damping body of rod can guarantee that the damping body of rod can not swing between limiting stopper and the locking nut in the damping housing and be arranged on, and guarantees the giving full play to of shock-absorbing function of vibration damper.The utility model is simple in structure, easy to use, good damping effect, and long service life.
