Description

The standpipe of bicycle combining device

Technical field

The present invention relates to the technical field of bicycle, refer to especially a kind ofly have in conjunction with the good standpipe of bicycle combining device of effect.

Background technology

The modern stresses day by day for stress-relieving activity, and the stress-relieving activity that the modern pursues, not only will be with leisure, motion, amusement etc. multi-functional, so wherein most popular recreation tool, be bicycle, it not only can be walking-replacing tool, has more above-mentioned multiple function, in addition, bicycle more has multiple use such as motion and match.

The standpipe of bicycle combining device of general traditional usefulness, as shown in Figure 7, it comprises cushion block 50, a vertical tube 60 and a capping 70 of several push pipe 10 peripheries that are sheathed on bicycle front tube 11 tops.These push pipe 10 central authorities are provided with a fixed plate 12, wherein, these push pipe 10 peripheries are arranged with a plurality of cushion blocks 50, and an end of this vertical tube 60 is provided with the c-shaped joint portion of a section 61, be sheathed on this push pipe 10 for this joint portion 61, and be positioned at this cushion block 50 tops, and cooperate, cooperate this capping 70 to be resisted against this vertical tube 60 end faces again sealed the tightening of these joint portion 61 opening parts, and spiral shell is provided with a bolt 71, run through this capping 70, and be locked in this fixed plate 12, and this vertical tube 60 is fixed in this push pipe 10.

But, still have its defective on the standpipe of bicycle combining device of its traditional usefulness, therefore using in the enforcement, because it is cylindrical that this vertical tube, cushion block are all established, and radially just tighten combination by the joint portion of this vertical tube, and following in the situation of using a period of time or not locking, make to produce between this vertical tube and this push pipe relative rotation is arranged, cause the deflection of vertical tube angle, cause the user to drive the wayward tap of bicycle, and the danger that drives easily.

For improving above-mentioned standpipe of bicycle combining device, also have the combining device of a kind of vertical tube that can effectively locate and outer tube on the market, checked and approved patent No. 5588336 as the U.S., though it can effectively locate the angle between this vertical tube and outer tube, and can adjust the height of this vertical tube with respect to this outer tube, but, and still have problem in conjunction with the effect deficiency because combination is tightened in the simple joint portion of this vertical tube of leaning on.

Summary of the invention

The present inventor still has in conjunction with poor effect because aforementioned conventional uses the standpipe of bicycle combining device on reality is used, and this vertical tube effectively shortcoming of orientation angle exists, and is redesigned.

Main purpose of the present invention is for providing a kind of standpipe of bicycle combining device, and it can effectively prevent to produce mutual rotation between this vertical tube and outer tube, has more in conjunction with the good effect of effect.

In order to reach aforesaid goal of the invention, the technological means that the present invention used is to provide a kind of standpipe of bicycle combining device, and it comprises:

One can be sheathed on the outer tube of bicycle push pipe, and the periphery of this outer tube is axially arranged with a profile groove; One vertical tube, an end of this vertical tube is provided with the joint portion of a hollow form, and this joint portion inner peripheral is the not relative combination of rotating with this outer tube; It is characterized in that,

Described outer tube one distal process is provided with a beam ring, and the opening part of this beam ring is one to be the opening that tight pencil is dwindled;

Described joint portion periphery cuts open and is provided with one and is the opening that tight pencil is dwindled, and makes this joint portion can tightly restraint the top side that is incorporated into this outer tube.

Wherein, the c-shaped shape of this outer tube section, and periphery differs from opening part and axially is equipped with a raised line, and be equipped with the beam ring of a ring in this bottom surface, and this vertical tube is provided with a position-limited trough that is embedded in this raised line relatively, but combine fixingly for this outer tube actv. with this vertical tube, make between this outer tube and this vertical tube can not produce relative rotation, increase between the two in conjunction with effect.

The present invention utilizes above-mentioned technological means, and after implementing, because this outer tube is provided with the raised line of standing shape, and the joint portion of this vertical tube is provided with this position-limited trough relatively, be concavo-convex chimeric for the raised line of this outer tube and the position-limited trough of this vertical tube, and can effectively prevent rotation between this outer tube and vertical tube, and be provided with the beam ring of a c-shaped shape by an end of this outer tube, tightly restraint for this beam ring, and this outer tube one end can be packed in this push pipe, cooperate the tight bundle of this vertical tube, reach firm this push pipe periphery that this outer tube is fixed in, and reduce the skew of this vertical tube angle, increase the steadiness of combination and the safety that use drives.
