Abstract

The utility model relates to a bicycle vertical pipe, in particular to an aluminium vertical pipe of bicycle that is wear preventive. One end of the utility model is used for locking and fixing a frame, the other end of the utility model is used for locking and fixing a handlebar, and the utility model includes a pipe body, one end of the pipe body is provided with a base provided with a semicircular gripping surface; a fastening sleeve which is arranged on the other end of the pipe body and used for locking and fixing the frame; and a cover body which is provided with the semicircular gripping surface and can be locked and fixed on the base, thereby ensuring that the semicircular gripping surface of the cover body and the semicircular gripping surface of the base are formed into a trepan boring to clamp the handlebar; the utility model further includes an iron sheet that is semicircular by looking from a side view, the inner surface of the iron sheet is bestrewed by horizontal jugged stripes, the iron sheet is stuck to the base and at least one gripping surface of the cover body, the inner round surface of the iron sheet is contacted with the outer round surface of the handlebar directly. The outer surface of the iron sheet of the utility model is also bestrewed by horizontal jugged stripes. Compared with the prior art, the utility model has the advantages that the aluminium vertical pipe from scuffing and wearing by the jugged stripes used for performing handlebar can be prevented completely, the utility model can clamp the handlebar firmly all the time, and the performer can perform at ease.

Description

Bicycle aluminum standpipe with iron plate

Technical field

The utility model relates to a kind of bicycle profile tube, especially a kind of bicycle aluminum standpipe that provide protection against wear.

Background technology

Be illustrated in figure 1 as the scheme drawing of the bicycle aluminum standpipe 1 of prior art, the bicycle of general performance usefulness, its standpipe is to adopt aluminum metal to make and make without iron substantially, major cause is that aluminum standpipe material is lighter, flexibly light and handy during performance, iron standpipe is then heavier.Though the aluminum standpipe has the advantage of light weight, general performance bicycle, the time and jump onto, the time and jump off, even upset, these actions make performance bear great strength with bicycle handle 2 (general handle is all iron), though aluminium light weight matter is soft, the groove of this handle 2 is the clamping face of 4 meeting scratch pipe clamps 3 partly, the groove that causes the clamping handle 2 that pipe clamp 3 can not be tightly partly 4 has the possibility that gets loose, for the performing artist, not only influence performance, in addition also dangerous.

Summary of the invention

The utility model purpose is to provide a kind of bicycle aluminum standpipe with iron plate, can prevent fully that the aluminum standpipe from being performed the groove scratch of handle and wearing and tearing, and clamps handle all the time.

The utility model adopts following technical scheme for achieving the above object: have the bicycle aluminum standpipe of iron plate, the one end is in order to the locking vehicle frame, and the other end comprises in order to the locking handle: a body, and the one end is provided with the pedestal with a semicircle clamping face; One locking sleeve is located at the body other end in order to be locked in vehicle frame; And a lid, have a semicircle clamping face, can be locked on the pedestal, and make the clamping face of its clamping face and pedestal be combined into a circular trepanning with the clamping handle; It also further comprises the iron plate of the semicircular in shape of a side sight, and the iron plate inside face is covered with horizontal profile of tooth striped, and this iron plate adheres on pedestal and lid at least one clamping face wherein, and the iron plate inner headed face directly contacts with the handle periphery.

Bicycle aluminum standpipe with iron plate of the present utility model, the outside face of its iron plate also is covered with horizontal profile of tooth striped.

Bicycle aluminum standpipe with iron plate of the present utility model, the outside face of its iron plate can be polygon.

The utility model compared with prior art can prevent fully that the aluminum standpipe from being performed the groove scratch of handle and wearing and tearing, and clamps handle all the time, makes the performing artist feel at ease to perform.

The specific embodiment

At first, see also Fig. 2 and cooperate shown in Figure 3, the utility model includes the iron plate 20 of an aluminum standpipe 1 and a side semicircular in shape, wherein, this aluminum standpipe 1 comprise a body 101, a locking sleeve 102 be located at body 101 1 ends in order to be locked in vehicle frame (end shows among the figure), and a lid 103 have a semicircle clamping face 104.And body 101 other ends are provided with the pedestal 106 with a semicircle clamping face 105, and the surface of this clamping face 105 is covered with horizontal profile of tooth striped 100.This lid 103 is locked on the pedestal 106 by means of a plurality of bolts 107, and makes its clamping face 104 and the clamping face 105 of pedestal 106 be combined into a circular trepanning with clampingc car handle 2.And topmost two surfaces of this iron plate 20 that are characterised in that of the utility model all have horizontal profile of tooth striped 201,202.And semicircle iron plate 20 is inserted from clamping face 105 side in alignment tooth bars 100, and makes iron plate 20 adhere on clamping face 105.In case when cooperating lid 103 assemblings to go up handle 2, the profile of tooth bar 201 that just makes iron plate 20 directly with the profile of tooth striped of handle 2 partly 4 because iron plate 20 and handle 2 are all iron material matter, and iron material matter is harder, admittedly its contact surface that is difficult for fraying.

As shown in Figure 4, if also posted this iron plate 20 in the above described manner at the clamping face 104 of lid 103, then two clamping faces 104,105 all post iron plate 20, more can increase the effect of clamping handle 2.

No matter which kind of shape clamping face 105 is, as long as the surface of iron plate 20 cooperates with it, iron plate 20 can be adhered on clamping face 105.Please cooperate and consult Fig. 5, the outside face of this iron plate 20 also can be designed to polygon and adhere on the pedestal 106 (as Fig. 6) with polygon clamping face 105 with cooperation.Consulting Fig. 7 again is the scheme drawing that iron plate 20 is placed the polygonal clamping face 105,104 of pedestal 106 and lid 103 respectively.The utility model can prevent fully that the aluminum standpipe from being performed the groove scratch wearing and tearing of handle, clamps handle all the time, the person's safety, relieved that makes the bicycle.
