Description

Bicycle folder

[technical field]

The utility model relates to a kind of bicycle, refers in particular to the folder on the Folding Bicycle.

[background technology]

Our country is a bikedom, and present stage, bicycle not only became people's walking-replacing tool along with the raising of people's living standard, also becomes people and removes the field body-building when movable, the tool movement of leisure such as go for an outing.In order to make bicycle be easy to carry, collect keeping, people have made light and handy Folding Bicycle attractive in appearance.But the folder structure more complicated of current Folding Bicycle, and lost efficacy easily, there is certain potential safety hazard, so be necessary fully to improve.

[utility model content]

The purpose of this utility model is to be to overcome the deficiencies in the prior art, and a kind of simple in structure and reasonable, safe and reliable bicycle folder is provided.

In order to solve the technical matters of above-mentioned existence, the utility model adopts following technical proposals:

The utility model is a kind of bicycle folder, it includes hinged preceding foldable base of an end and back foldable base, in the folding hole of the preceding foldable base other end, be provided with and rotate therein and axially movable folding actuating spindle, be respectively equipped with open slot and folding control punch in the both sides of this back foldable base other end; End at folding actuating spindle is provided with handle, and the other end can be inserted into when folded state in this folding control punch; On the folding actuating spindle of that section between the two folding holes of this preceding foldable base, be respectively equipped with spring and helical orbit, be provided with the track pin to this helical orbit guiding on this preceding foldable base, folding actuating spindle comes along this track pin spiral lifting by the helical orbit on it.

As improvement project to above-mentioned bicycle folder, on the folding actuating spindle that is positioned at this spring one side, be provided with pushing pin, on this back foldable base, be provided with the pushing block that can act on this pushing pin; One end of described spring just keeps off on this pushing pin.

As the improvement project to above-mentioned bicycle folder, described pushing block is the L-square that is welded on this back foldable base.

As the improvement project to above-mentioned bicycle folder, described helical orbit is a spiral groove.

Compared with prior art, 1), after the utility model is installed on the Folding Bicycle the beneficial effects of the utility model are:, when the collection bicycle, swing handle makes on the folding actuating spindle screw and skids off folding control punch up to control end, at this moment just bicycle folding can be got up place; When launching bicycle when using, earlier forward and backward foldable base is closed up, then rotate folding actuating spindle, get final product in the folding control punch after control end is inserted into again on the foldable base, so it is of the present utility model relatively simple for structure and reasonable, bring it simple to operate and easy to use, also more safe and reliable; 2), in prioritization scheme of the present utility model, because when closing up folder, folding actuating spindle its control end when spiral descends is inserted in the folding control punch of back foldable base automatically comes the auto lock folder, and when the unfolded device, can help folding control axial screw to rise by the antagonistic force between spring and pushing pin, can save the strength that turns handle like this, so the operation in preferred version of the present utility model is simple more, convenient.

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:

[specific embodiment]

The utility model is a kind of bicycle folder, it includes an end by adapter shaft 1 hinged preceding foldable base 2 and back foldable base 3, in the folding hole 21 of preceding foldable base 2 other ends, be provided with and rotate therein and axially movable folding actuating spindle 4, be respectively equipped with open slot 31 and folding control punch 32 in the both sides of these back foldable base 3 other ends; End at folding actuating spindle 4 is provided with handle 5, and the control end 41 of the other end can be inserted into when folded state in this folding control punch 32, and this moment, one section folding actuating spindle between handle 4 and preceding foldable base 2 was ensconced in this open slot 31; On the folding actuating spindle 4 of that section between the two folding holes 21 of this preceding foldable base 2, be respectively equipped with spring 6 and helical orbit 7, on this preceding foldable base 2, be provided with track pin 8 to this helical orbit 7 guiding, folding actuating spindle 4 by the helical orbit on it 7 along these track pin 7 spiral liftings.After this folder closed up, rotate folding actuating spindle 4 with handle 5, after making it spiral decline, the control end 41 of its lower end is inserted in the folding control punch 32 of back foldable base 3, locking securely after so just the forward and backward part of Folding Bicycle can being launched is ridden bicycle with that and is come body-building, lies fallow or ridden instead of walk.So of the present utility model relatively simple for structure and reasonable, bring it simple to operate and easy to use, also more safe and reliable.

Present embodiment also is provided with pushing pin 9 as preferable embodiment on the folding actuating spindle 4 that is positioned at these spring 6 one sides, be provided with the pushing block 10 that can act on this pushing pin 9 on this back foldable base 3; One end 61 of described spring 6 just keeps off on this pushing pin 9.Like this, when closing up folder, folding actuating spindle 4 its control end 41 when spiral descends is inserted in the folding control punch 32 of back foldable base 3 automatically comes the auto lock folder, and when the unfolded device, can help the spiral of folding actuating spindle 4 to rise by the antagonistic force of 9 of spring 6 and pushing pins, can save the strength that turns handle 5 like this, so the operation in preferred version of the present utility model is simple more, convenient.

Shown in Fig. 4,6, pushing block 10 is for being welded on the L-square on this back foldable base 3, and helical orbit 7 is the direct spiral groove that processes from folding actuating spindle 4 simultaneously, certainly, it also can be other structure, if can realize and track pin between spiral lifting.
