Abstract
The utility model provides an adjustable shock damping rod for a saddle, and is characterized in that the lower end of a round inner core is fixedly connected with an inner rod whose cross section is in the shape of an internally tangent polygon, the outer lateral side is sheathed with a hollow round outer tube whose lower end is provided with a connecting head matched movably with the inner rod, and the upper and the lower ends of an extension spring are respectively matched and connected with the connecting head and the inner rod through screw thread. The utility model has the advantages of simple structure, convenient production and installation, long shock damping stroke, wide, flexible and convenient adjustment range of the elastic force, strong applicability, stable performance, reliability, long service life, etc., and can be used for reforming the existing shock damping mechanism for the saddle.
Description
The utility model relates to a kind ofly is located on the vehicle frame and the elasticity saddle annex of parallel motion up and down especially a kind of adjustable saddle decoupling rod of bicycle use.
The bicycle saddle great majority that use all adopt the shock-damping structure that mobile jib is fixed, the seat cushion bottom is provided with several compression springs now.Because the intensity of compressibi1ity spring and compressiblely all be restricted, and the short defective such as unadjustable again of compression stroke, its practical effect is not very good.Middle circle patent CN2217549Y discloses a kind of " bicycle elasticity saddle pipe ", its keystone configuration feature is to be with the sliding sleeve that is connected with body on the axle of keyway having, the axle bottom is inserted with the bottom and is connected with the push rod that hangs spring, and this top of hanging spring fixes on the body towards rivet clasp.Stretching, rebound performance that this elasticity saddle pipe hangs spring by up-and-down movement between axle and sliding sleeve and axle bottom come bumper and absorbing shock.Though it is more quite a lot of than traditional compressibi1ity spring saddle effect, structure is more complicated, and it is all convenient inadequately to make and install, it uses keyway and pin etc. in addition directed, stable inadequately, reliable, it is less thereby comformability is not strong to hang the spring force range of regulation, so its result of use still can not be satisfactory.
The purpose of this utility model just is to overcome above-mentioned the deficiencies in the prior art part, provide a kind of simple in structure, it is convenient to make and install, the damping stroke is longer, the elastic force adjusting range is big and regulate flexible, convenient, applicability is strong, and in-use performance is stable, reliable, the adjustable saddle decoupling rod of long service life.
The purpose of this utility model can reach by adopting following technical proposal: the lower end of a circular inner core be fixedly connected with transversal surface be inscribe polygonal in bar, its outside is with hollow circular outer pipe, the lower end of this outer tube is provided with the connector of inboard and above-mentioned interior bar running-fit, its underpart connects a drawing spring, lower end being connected with the screw thread activity of the lower end of this drawing spring and above-mentioned interior bar.Described circular inner core can be a pipe in the hollow circle, to alleviate overall weight, makes action more flexible; The transversal surface of bar preferably is the inscribe square in described, is convenient to processing, installs and rises directional tagging; The lower end of above-mentioned outer tube makes its positioning action stable, reliable with the described connector of the fixing assembling of welding manner; But packing lubrication grease in the formed cavity between by outer tube and interior bar to reduce the friction between inner core and interior bar and the outer tube, increases alerting ability.
Accompanying drawing 1 is the structural representation of the utility model embodiment.
Accompanying drawing 2 is an A-A generalized section among the utility model embodiment.
Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail: in a hollow circle pipe 1 lower end socket fix a cross-sectional plane be inscribe just tetragonal in bar 2, its outside is with hollow circular outer pipe 3, the lower end of this outer tube 3 is welded with the connector 4 of an inboard and above-mentioned interior bar 2 running-fits, the bottom of this connector 4 offers the outside thread 5 that matches with drawing spring 6 tops, and the outside thread 7 that the bottom of described drawing spring 6 is offered by interior bar 2 bottoms is connected with its activity.Be filled with machine oil in the cavity 8 between above-mentioned hollow circular outer pipe 3 and interior bar 2.When using the utility model product, only need common bicycle saddle is installed in the upper end of pipe 1 in the above-mentioned hollow circle, hollow circular outer pipe 3 has been fixed in the vehicle frame corresponding position just.For the personnel of different weight, only need by rotate above-mentioned drawing spring 6 make in the lower external thread 7 of bar 2 be in appropriate location on the drawing spring 6, just can adjust its effective length and obtain different elastic force.Since connector 4 inboard with the running-fit of interior bar 2 and the effects of machine oil, make above-mentioned in bar 2 in hollow circular outer pipe 3, be able to orientation, up-and-down movement neatly, play good damping effect.
The utility model is compared with technology with existing, has simple in structurely, and it is all convenient to make and install, damping Stroke is long, the wide and flexible adjustment, convenient of elastic force adjusting range, and applicability is strong, and serviceability is stable, reliable, The characteristics such as long service life especially are fit to improve existing bicycle saddle damping.
