Technical field

The utility model relates to folding bicycle folder technical field, relates in particular to a kind of folding bicycle folder of strengthening locking action that has.

Background technology

At present, be equiped with folder on the folding bicycle between the pipe fitting through being everlasting, use the jackknife action between the operation pipe fitting, common folder is installed on the main car frame and (is beneficial to vehicle frame folding), between handlebar stem and the front fork tube on (being beneficial to handlebar stem downwards folding) or the seat bar (being beneficial to seat cushion downwards folding), the position that the contexture aspect of folder and installing are used is a lot of.In the prior art, the folder of installing on the folding bicycle generally is that branch has left and right housing, and wears and articulate by an axostylus axostyle in a side, makes can close up between the left and right housing or be that the axle center is done and launched action with this axostylus axostyle; Non-pivot joint side between left and right housing then is provided with a quick detach group, this quick detach group can be when left and right housing closes up, left and right housing is produced locking action, left and right housing can't be thrown off voluntarily easily, therefore must come the unlocked effect via this quick detach group of operation, the side is able to left and right housing is launched.So the folder of installing on the folding bicycle can be distinguished into following two kinds of states in the use at present:

(no matter the locking of quick detach group or non-locking) do not done folding when 1, the left and right housing of folder closed up between two pipe fittings that folder is set up.

When 2, the left and right housing of folder launched, the quick detach group must be non-locking, and had done folding between two pipe fittings set up of folder.

At present, the folder of installing on the folding bicycle produces locking action with the left and right housing to folder when left and right housing is closed up and via this quick detach group of operation, and the general locking action that quick detach group itself is produced is called first and re-locks effect.Because general quick detach group all has a lever, produce locking action or unlocked effect with handled easily quick detach group, that is no matter be to produce locking action or want the unlocked effect, this lever is operated in the capital, therefore only have the folder of first weight (substance) locking action on reality is used, can exist this lever easily because being shaken or being touched the misgivings that (or hitting) is offset (unlocked) unintentionally, especially folding bicycle is the movement of advancing in the environment for use of regular vibrations, if so this lever skew suddenly and locking of untiing folder probably will cause the rider to produce serious disaster in incognizance.

Therefore just there was the folding bicycle folder of tool double locking effect to produce afterwards, be the folding bicycle folder of first kind of tool double locking effect commonly used as shown in Figure 1, this folder has a left shell 11 and a right shell body 12, engages with first and second car pipe fitting 111,121 respectively; Left and

right housing

11,12 wears and articulates by an axostylus axostyle in a side, makes left and

right housing

11,12 to close up or is that the axle center is done and launched action with this axostylus axostyle; Then be provided with a quick detach group 13 in left and

right housing

11,12 non-pivot joint side, its outside obviously has an operating handle 131, namely uses in order to the intraware change of operating this quick detach group 13; When left and

right housing

11,12 closes up, can close up to the second car pipe fitting, 121 directions by pulling this operating handle 131, so that producing first to left and

right housing

11,12, the intraware of this quick detach group 13 re-locks effect; Then be installed with a card body 14 in addition in these second car pipe fitting, 121 outsides, for tool is upheld elastomeric material forming, the opening part of card body is done recessed shape, when this operating handle 131 can touch this card body 14 when the second car pipe fitting, 121 directions are closed up, and inwardly clamp-ons to do the location; Therefore reaching second by grasping of 14 pairs of operating handles 131 of this card body re-locks effect.But the weak point of this double locking is that this card body 14 is not weather-proof, and the long period is blocked the extension elasticity of body with rapid drawdown when using, thereby causes second effect of re-locking loose.

Shown in Figure 2 then is the folding bicycle folder of second kind of tool double locking effect commonly used, and folder has a left shell 11 and a right shell body 12 equally, engages with first and second car pipe fitting 111,121 respectively; Left and

right housing

11,12 wears and articulates by an axostylus axostyle in a side, makes left and right sides housing 11,12 to close up or is that the axle center is done and launched action with this axostylus axostyle; Then be provided with a quick detach group 13 in left and

right housing

11,12 non-pivot joint side, its outside is by the change action of an operating handle 131 these quick detach group 13 intrawares of operation; When left and

right housing

11,12 closes up, pull this operating handle 131 and close up the intraware that can make this quick detach group 13 to the second car pipe fitting, 121 directions and left and

right housing

11,12 is produced first re-lock effect; In addition, offer a jack 132 on this operating handle 131, can pull the work registration device 15 of deflection up and down and be equiped with one at these second car pipe fitting, 121 contiguous these jack 132 places, be mainly its bottom and have a clipping block 151, therefore when this operating handle 131 closes up fully to the second car pipe fitting, 121 directions, can pull this registration device 15 to operating handle 131 direction deflections, as shown in Figure 3, make this clipping block 151 support into this jack 132 and do the location; Therefore reaching second by the clip of 151 pairs of operating handles 131 of this clipping block re-locks effect.But the weak point of this double locking is that this registration device 15 is for simply being articulated on this second car pipe fitting 121, therefore regular vibrations of use kind meeting and easily loose, cause when the operation folding bicycle is done jackknife action, must have on the other hand turning round and look at this registration device 15 and do not fall, make the operation folding bicycle do folding action and become and very have some setbacks.Moreover, when this registration device 15 is loose, also may occur in the process of driving, because the clipping block 151 of this registration device 15 jumps out of this jack 132, and second effect of re-locking is removed suddenly, relatedly cause unpredictable danger.
