Abstract
The utility model discloses a shock preventing seat pipe for a bicycle, which has the advantages of swing prevention of a cushion and simple structure. The utility model is composed of an outer pipe, an inner pipe, a sliding sleeve, a dust preventing sleeve and a damping spring, wherein the outer pipe and the inner pipe are hollow pipe bodies, the damping spring and the inner pipe are assembled in the outer pipe, the inner pipe periphery which is arranged outside the outer pipe is provided with the telescopic dust preventing sleeve and the inner pipe periphery which is arranged inside the outer pipe is provided with the sliding sleeve. Furthermore, a section of pipe diameter is expanded on the lower side of the inner pipe after the outer pipe is assembled with the inner pipe and the damper spring is abutted to an opening of the pipe diameter after expansion in a pressing way. The utility model with the structure can effectively solve the technological problem that the seat pipe for a bicycle can swing after long time use because an expanding pipe is used for processing after the assembly of the outer pipe and the telescopic inner pipe.
Description
Technical field
The utility model relates to a kind of bicycle saddle tube, specifically a kind of have prevent seat cushion beat and automatic shock-proof seat pipe simple in structure.
Background technology
The current bicycle saddle tube of commonly using, be connected with bicycle saddle cushion on the top, the bottom generally is located on the standpipe of cycle frame, also is provided with other damping parts of damping spring, interior pipe or the like in the present pipe, and interior pipe is pressed against abutment pad damping, buffering effect on the damping spring.Because each component part of seat pipe all is to adopt movable connection, part is more in the assembling, more complicated, and cost is corresponding also can be increased.In use manage upper and lower slip damping in the seat pipe and can make a person feel pleasant, but after the time grown, can make seat cushion generation beat slippage in various degree, mainly be because interior pipe and seat pipe all adopt straight circular body, after processing, be assembled into one again earlier, in order to prevent that beat from generally adopting cap bag to screw the connecting element that mode is fixed or other is equal to mutually in the caliber periphery and fixing, exterior connecting element run into for a long time vibrations can produce loosening, thereby influence the seat cushion beat.
Summary of the invention
The purpose of this utility model is to provide a kind of bicycle saddle tube, it can solve effectively that existing bicycle saddle tube is long-time can beat after using technical barrier, and can reduce parts, be easy to assembling.
In order to achieve the above object, the utility model is realized by following technical scheme.
A kind of bicycle saddle tube, form by outer tube, interior pipe, sliding sleeve, dust protecting cap, damping spring, wherein, outer tube, interior pipe are hollow tube, assembling damping spring, interior pipe in the outer tube, interior pipe place the outer pipe periphery of outer tube to be provided with scalable dust protecting cap, and interior pipe places the pipe periphery in the outer tube to be provided with sliding sleeve, it is characterized in that: pipe back one section caliber of expansion below interior pipe in the outer tube assembling, damping spring is pressed against the caliber mouth after the expansion;
The caliber periphery of pipe after expansion do not have the sliding sleeve of establishing in described.
The utility model beneficial effect is, adopted the bicycle saddle tube of the utility model structure, since outer tube with scalable in pipe assembling back use expander process, interior pipe will be fixed in the outer tube and move, be exactly to use for a long time, can not get loose yet, can solve the technical barrier of meeting beat after bicycle saddle tube uses for a long time effectively.And total lacked the excessive zero parts that interior pipe and outer tube tighten up, and reduced integral vehicle cost, and is simple in structure, is easy to assembling.
Description of drawings

The specific embodiment
Below in conjunction with description of drawings the specific embodiment of the present utility model is further elaborated.A kind of bicycle saddle tube as shown in Figure 1 mainly is made up of outer tube 5, interior pipe 2, sliding sleeve 4, dust protecting cap 3, damping spring 6.Wherein, outer tube 5, interior pipe 2 are hollow tube, and the inner tubal wall of outer tube 5 can be set as polygon, and interior pipe 2 outer tube walls also are provided with the polygon that matches with the inner tubal wall of outer tube 5.The top of interior pipe 2 is equipped with a plug 1 and sets firmly with bicycle saddle cushion.An end of assembling damping spring 6, interior pipe 2 in the outer tube 5.The interior pipe 2 pipe peripheries that place outer tube 5 to expose are provided with scalable dust protecting cap 3, and interior pipe 2 places the pipe peripheries in the outer tube 5 to be provided with sliding sleeve 4.Sliding sleeve 4 is to be arranged with in outer tube 5 inwalls by a barb salient point 41, and barb salient point 41 is to be used to tighten up sliding sleeve 4.Pipe 2 backs one section caliber 21 of expansion below interior pipe 2 in outer tube 5 assemblings, from Fig. 1, can clearly show, caliber 21 peripheries of interior pipe 2 after expansion do not have the sliding sleeve of establishing 4, make its caliber 21 after expansion can utilize sliding sleeve 4 to come blocking to live, corresponding interior pipe 2 just can not deviate from outer tube 5 after sliding sleeve 4 blockings.One end of damping spring 6 is pressed against the caliber mouth after the expansion, and the other end is pressed against the inboard of outer tube bottom 8 by a pad 7, and outer tube bottom 8 outsides are fixing with a C type ring 9.What adopt in 6 accompanying drawings 1 of damping spring is omissive representation, and the effect of damping spring 6 is not on the basis of beat, can reach an effect of person's shock-absorbing at the control seat cushion again.
Claims (4)
1, a kind of bicycle saddle tube, form by outer tube, interior pipe, sliding sleeve, dust protecting cap, damping spring, wherein, outer tube, interior pipe are hollow tube, assembling damping spring, interior pipe in the outer tube, interior pipe place the outer pipe periphery of outer tube to be provided with scalable dust protecting cap, and interior pipe places the pipe periphery in the outer tube to be provided with sliding sleeve, it is characterized in that: pipe back one section caliber of expansion below interior pipe in the outer tube assembling, damping spring is pressed against the caliber mouth after the expansion.
