Abstract
The utility model discloses a concentric rotation type bicycle handlebar folding device. One end of one rotary movable block and one end of the other movable block are respectively connected with transverse pipes of a left and a right handlebars. The other end of each of the rotary movable blocks is movably connected with the same end of a fixed head of a vertical pipe. An eccentric quick dismounting component is penetrated in the two rotary movable blocks. The utility model can effectively balance the two handlebars, so that the utility model has the advantages of uniform dispersed stress, no occurrence of swing phenomenon, and safe, reliable and convenient use. Simultaneously, the quick dismounting component of the utility model is divided into a separation type quick dismounting component and a no separation type quick dismounting component. The separation type eccentric quick dismounting component can be carried off after folded for performing the certain function of theft protection. The no separation type eccentric quick dismounting component is rapid, simple and convenient when used.
Description
Technical field
The utility model relates to a kind of concentric running formula bicycle cross handle folding device.
Background technology
In the prior art, about the folding technical scheme of bicycle handle, generally adopt the quick detach assembly that the handle of bicycle is folded, and wherein so that Fast detachable unit to be installed on the standpipe, as ZL00268393.8 and ZL03267722, the quick detach assembly all is arranged on the standpipe.Bicycle so that this folding mode constitutes in use owing to the effect of human body weight, can cause the overbalance of handle.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned defective, and a kind of safe and reliable concentric running formula bicycle cross handle folding device is provided.
In order to achieve the above object, two rotary moveable pieces, standpipe fixed head and eccentric quick detach assemblies about folding device of the present utility model comprises; Eccentric quick detach assembly is provided with double-screw bolt, and the one end is the quick detach handle, the sheathed nut of the other end; One end of two rotary moveable pieces is connected with left and right sides handle transverse tube respectively, and the same end of the other end and standpipe fixed head flexibly connects; Eccentric quick detach assembly is located in two rotary moveable pieces.
Owing to adopted such scheme, folding device of the present utility model to be arranged on the bicycle cross handle, balance both sides handle makes stressed being uniformly dispersed effectively, can not produce the phenomenon of waving, and uses safer, reliable, convenient.Simultaneously quick detach assembly of the present utility model divides disengaged and two kinds of disengageds not, and the eccentric quick detach assembly of disengaged can be taken away after folding, and plays certain antitheft effect; Disengaged is then faster in use not easy.

Fig. 3 is the constitution diagram of device after folding of Fig. 1;
Fig. 4 is the constitution diagram of the another kind of embodiment of the utility model after folding;
Fig. 5 is the structure of right rotation movable block;
Fig. 6 is the constructional drawing of anticlockwise movable block among Fig. 4.
The specific embodiment
As shown in Fig. 1 and Fig. 2, left rotation and right rotation movable block 2 and an end of 3 are captiveed joint with the mode of left and right sides handle transverse tube 1 and the welding of 4 usefulness respectively, and the same end of the fixed head 6 of the other end and stem 15 is by roller pin 7 flexible connections.As shown in Figure 5, the rotary moveable piece is provided with the screens 14 of protrusion at the roller pin coupling end, and the standpipe fixed head is provided with corresponding positive stop lug boss 12, but the rotation of screens and positive stop lug boss mutual action restraint piece; Also be provided with counterbore fluting 13 on the movable block, among the embodiment of Fig. 1, about two rotary moveable pieces be equipped with fluting.An end of double-screw bolt 9 is a quick detach handle 8 in the quick detach assembly 5, the sheathed nut 10 of the other end, and the quick detach assembly is located on two rotary moveable pieces by double-screw bolt 9 and fluting 13.
Pull the quick detach handle when folding, unclamp locking, whole quick detach assembly is taken out from the counterbore fluting movable head; Inside then rotary moveable piece, when the rotary moveable piece touched the positive stop lug boss of fixed head, rotation stopped, and finished jackknife action.When needing to use bicycle, outside rotary moveable piece, when screens touched positive stop lug boss, rotation stopped; Put into the quick detach assembly in the counterbore from fluting this moment, mixes up the position of nut, utilizes eccentric action to lock two rotary moveable pieces again, prevents its rotation.
Fig. 4 and shown in Figure 6 be the another kind of embodiment of the utility model, most of structure is identical with embodiment 1, but on two rotary moveable pieces, one of them is provided with counterbore fluting 13, and another is provided with rotation axis hole 16, is provided with S. A. 11 in the position of rotation axis hole, in order to use smoothly, generally the counterbore fluting is arranged on the right rotation movable block, the rotation axis hole then is arranged on the anticlockwise movable block.S. A. 11 reality are the member in the eccentric quick detach assembly 5, are set in an end of close nut 10 on the double-screw bolt 9.Need hold the quick detach handle when folding, drive double-screw bolt and in S. A., be rotated, make the quick detach assembly can break away from the counterbore fluting of right rotation movable block, and stay on the anticlockwise movable block; Open when folding and move on the contrary.
