Description
Technical field
The utility model relates to a kind of bicycle profile tube, concrete relates to a kind of bicycle folding standpipe.
Background technology
Bicycle is popularized as a kind of traffic, tool movement already; Yet; Because all there is the problem that takies on the space in common bicycle when carrying or deposit; Therefore a kind of folding bicycle popularizing just slowly, described folding bicycle is modified as two sections or three sections through one or more fold mechanisms in general sense on vehicle body originally.
Existing fold mechanism; Basically be to constitute by following technical scheme; Comprise the last pivot part and the following pivot part that is used to be connected second standpipe that are used to connect first standpipe that are connected through the hinge; Also be provided with a blocking device between said upward pivot part and the following pivot part, can accomplish folding or being connected of first standpipe and second standpipe through opening or pin described blocking device.Yet the blocking device of existing fold mechanism, or complex structure, or the release phenomenon appears when collision.
The utility model content
For overcoming the problems of the prior art, it is a kind of simple in structure that the purpose of the utility model is to provide, and can not occur the phenomenon of false triggering release during collision.
In order to solve the problems of the technologies described above, realize above-mentioned purpose, the utility model has adopted following technical scheme:
A kind of bicycle folding standpipe comprises upper riser and lower standing tube, connects through a fold mechanism between said upper riser and the said lower standing tube; Said fold mechanism comprises on one foldable base and foldable base once; Said the same side of going up foldable base and following foldable base is connected through a rotating shaft is pivotable, the said upper riser said foldable base that goes up that is connected, the said lower standing tube said foldable base of descending that is connected; The said opposite side of going up foldable base is provided with a tapped bore; Be provided with a screw in the said tapped bore, the end of said screw is provided with a knob, is arranged with a fixed block on the screw rod body of said screw; The said opposite side of foldable base down is a Baltimore groove; Have gap on the said Baltimore groove; The said foldable base that goes up can be incorporated in the said foldable base down, and said screw is positioned at said opening position, and said fixed block can be fixed in the said Baltimore groove through the constantly tight supination of screw.
Further, the said screw end of inserting an end of said tapped bore is provided with a prominent circle.
Further, also be arranged with a spring on the screw rod body of said screw, an end of said spring is fixed on the said screw through a spring shim, the other end said fixed block that is connected.
Compared with prior art the utlity model has following advantage:
1, the bicycle folding standpipe of the utility model can simple and effectively will be gone up foldable base through fixed block and following foldable base is fixed; Because fixed block is through fixing foldable base and the following foldable base of going up of the tight supination of screw, therefore is not easy to produce the phenomenon that lock is misread in the collision back;
2, the screw end of inserting an end of said tapped bore is provided with a prominent circle, can prevent by actv. that screw is screwed out the phenomenon of position in unlocking process;
3, the setting of spring can guarantee that after last foldable base and following foldable base are incorporated into fixed block is realized contacting with the light of Baltimore groove through the elastic force of spring under free state, it is more convenient to make in operation.
Above-mentioned explanation only is the general introduction of the utility model technical scheme, in order more to know the technological means of understanding the utility model, and can implement according to the content of specification sheets, below with the preferred embodiment of the utility model and conjunction with figs. specify as after.The specific embodiment of the utility model is provided by following examples and accompanying drawing thereof in detail.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Label declaration among the figure: 1, upper riser, 2, lower standing tube, 3, go up foldable base, 301, tapped bore, 4, foldable base down, 401, Baltimore groove, 402, gap, 5, rotating shaft, 6, screw, 601, prominent circle, 7, knob, 8, fixed block, 9, spring shim, 10, spring.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the technical scheme of the utility model is further explained.
Referring to shown in Figure 1, a kind of bicycle folding standpipe comprises upper riser 1 and lower standing tube 2; Connect through a fold mechanism between said upper riser 1 and the said lower standing tube 2, said fold mechanism comprises on one foldable base 3 and foldable base 4 once, said on the same side of foldable base 3 and following foldable base 4 through 5 pivotable connections an of rotating shaft; The said upper riser 1 said foldable base 3 that goes up that is connected; The said lower standing tube 2 said down foldable base 4 that is connected, the said opposite side of going up foldable base 3 is provided with a tapped bore 301, is provided with a screw 6 in the said tapped bore 301; The end of said screw 6 is provided with a knob 7, is arranged with a fixed block 8 on the screw rod body of said screw 6; The said opposite side of foldable base 4 down is a Baltimore groove 401; Have gap 402 on the said Baltimore groove 401; The said foldable base 3 that goes up can be incorporated in the said foldable base 4 down; Said screw 6 is positioned at said gap 402 places, and said fixed block 8 can be fixed in the said Baltimore groove 401 through the constantly tight supination of screw 6.
