Abstract

The utility model relates to a bicycle vertical pipe used for fixedly locking a fork pipe 40 and a handlebar 50 of a bicycle. The utility model comprises a horizontal pipe 10 and restriction members 20, 30 which are connected to both ends 101, 102 of the horizontal pipe 10. The utility model is characterized in that the end 102 of the horizontal pipe 10 welded with the restriction member 30 used for fixedly locking the handlebar is in a pipe expanding design, namely, two opposite edges of the end 102 are outwards extended with convex rings 103, 104, the pipe opening of the end 102 is widen and expanded to be equal with the lateral length L of the restriction member 30, and the end 102 can be completely matched with the restriction member 30; the welding line of the end and the restriction member is lengthened, the weld strength is enhanced, and both ends of the restriction member can not be formed with salients; thereby, the appearance is beautiful, and the clothing can not be hooked easily.

Description

Bicycle profile tube

A kind of parts of the relevant what bicycle of the utility model are specifically related to a kind of bicycle profile tube of gaining in strength and having made it associative perception.

Existing Regular Bicycle standpipe is the bundle young 20,30 that comprises a transverse tube 10 and establish what transverse tube 10 two ends substantially as shown in Figure 1.Wherein bundle young 20 is in order to locking handle (not shown) in order to locking breeches pipe 40 and restraint young 30.Must earlier transverse tube 10 be made the draw before this transverse tube 10 and young 30 welding of bundle and handle, just transverse tube 10 calibers be diminished, cause so that young two ends of bundle 4,5 are horizontal to be gone out outside the what, not only profile is unbecoming, and easy what is hooked to thing.Especially draw processing is feasible less with the young 30 bonding area A of bundle, and intensity is relatively poor.In addition, the standpipe that has also cooperates outside locking nut 6, the 7 exposed whats, and young 30 water caltrops of whole bundle are too many.

Deficiency at above-mentioned known bicycle profile tube, the purpose of this utility model is to provide a kind of can strengthen the transverse tube of bicycle profile tube and the weld strength between the bundle son widely, and can with bundle son's screw and locking nut is covered and exposed what outside, the two ends of restrainting the son do not have coign thereby can not be hooked to the bicycle profile tube of anything fully.

Bicycle profile tube in order to lock respectively bicycle branch pipe and handle of the present utility model, system comprises that a transverse tube and two connects the bundle son at the both ends of what transverse tube respectively, wherein a branch of young locking breeches pipe, another bundle is young in order to the locking handle, its characteristic is the expander design in the transverse tube end system of the young welding of bundle of what and locking handle, be two relative edge's edge of end prominent rings that respectively stretch out, the lateral length that expands and restraint with making its end cross width widen the son to is suitable, make this end and this bundle son's weld line extend, and the unlikely two ends that should restraint the son form coign.

Compare with existing bicycle profile tube, bicycle profile tube of the present utility model, because the expander design is adopted in the end of transverse tube, make the transverse width of end widen, such widening Design clearly makes the end of transverse tube and the young weld line of bundle that the locking handle is used extend, strengthened transverse tube and the weld strength of bundle between the son widely, and bundle son's screw can have been covered by the end of transverse tube and do not expose outside the what; And two ends form coign, constitute a circular arc with the transverse tube end on the contrary, can not be hooked to anything fully.Also very attractive in appearance.

Below in conjunction with accompanying drawing bicycle profile tube of the present utility model is described further:

Fig. 1 is the cutaway view of known bicycle profile tube.

Fig. 2 is the cutaway view of bicycle profile tube of the present utility model.

Fig. 3 is the schematic perspective view of bicycle profile tube of the present utility model.

As shown in Figures 2 and 3, bicycle profile tube of the present utility model is identical with known bicycle profile tube shown in Figure 1, also comprise a transverse tube 10 and connect the bundle young 20 of what horizontal villous themeda 10 both

ends

101 and 102 respectively, 30, equally, the young 20 locking breeches pipes 40 of bundle, and bundle young 30 is in order to locking handle 50, the feature of bicycle profile tube of the present utility model is that then the end 102 of this transverse tube 10 is to be the expander design, the two relative edge's edge that the are about to end 102 prominent ring 103 that stretches out, 104, it is suitable to make its end mouth of pipe expand and restraint with widening young 30 lateral length L to, make this end 102 can with 30 perfect fittings, welded again.Because the expander design is adopted in the end of transverse tube 10 102, make the transverse width of end 102 widen, such widening Design clearly makes increases weld strength therebetween by the young 30 weld line B lengthening of this end 102 and bundle widely; Second the screw 301,302 of bundle young 30 can be covered by end 102 and exposed what outside; Thirdly, the design of the transverse width of end 102 is isometric with bundle young 30, and the two ends 303,304 of unlikely bundle young 30 form coign, constitutes a circular arc with end 102 on the contrary, can anything by hook fully.

Claims

A kind of bicycle profile tube, breeches pipe (40) and handle (50) in order to the bicycle that locks respectively, comprise a transverse tube (10) and connect the horizontal villous themeda of what (10) both ends (101) respectively, (102) bundle young (20), (30), bundle young (20) locking breeches pipe (40), and bundle young (30) is in order to locking handle (50), it is characterized in that the end (102) of transverse tube (10) with bundle son (30) welding of locking handle is to be expander design, the two relative edge's edge that are about to end (102) the prominent ring (103) that stretches out, (104), it is suitable to make the mouth of pipe of its end (102) expand and restraint with widening son's (30) lateral length L to, make this end (102) can with young (30) perfect fitting of bundle, welded again.
