Description
Technical field
The utility model relates to a kind of fold locking mechanisms of folding bicycle, belongs to the bicycle part field.
Background technology
Bicycle is one of vehicle of using always of people, in order to save the space, be convenient for carrying, people have developed folding bicycle on the basis of ordinary bicycle, and concerning folding bicycle, need be with bicycle handle bar and brake, the combination of preceding bar of bicycle and front fork is unclamped successively and is folded up, and under the bicycle state, must reliably above-mentioned parts be locked, therefore fold locking mechanisms is extremely important parts, be related to the folding comfort feature of whole folding bicycle, reliability, therefore the utility model applicant improves the fold locking mechanisms of bicycle in the prior art, has proposed a kind of later-model design concept.
The utility model content
The purpose of this utility model is to solve the above-mentioned technical matters that prior art exists, and a kind of simple in structure, failure-free fold locking mechanisms is provided.
The purpose of this utility model is achieved through the following technical solutions:
A kind of fold locking mechanisms, be used to lock or unclamp the vehicle frame of folding bicycle, described vehicle frame comprises preceding vertical rod, back vertical rod, be positioned at before vertical rod top the handle connecting rod and connect the intermediate bar of forward and backward vertical rod, described fold locking mechanisms comprises the key lever that is vertically fixed on the described intermediate bar, described back vertical rod is provided with a breach, described key lever enters or withdraws from described breach movably, described fold locking mechanisms also comprises a locking piece and controls the button of this locking piece that described locking piece prevents that key lever from withdrawing from from described breach.
Further, described locking piece is one to have the dead bolt of wedge surface.The bottom butt of described dead bolt has a spring, and described dead bolt is slidably disposed in the described back vertical rod, and the other end of described spring is against in the described back vertical rod.
Again further, described back vertical rod is two straight-bars that be arranged in parallel, and described locking piece is slidably disposed in one of them back vertical rod.
Further, be provided with projection in the breach of described another back vertical rod.
Again further, described folding bicycle includes baggages, and described key lever withdraws from the back and accommodated in the described baggages from described back vertical rod.
The beneficial effects of the utility model are mainly reflected in: adopt dead bolt and spring to control key lever and enter or withdraw from the back vertical rod, and simple in structure, convenient and reliable operation.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Fig. 1 is the block diagram of the utility model folding bicycle.
Fig. 2 is the scheme drawing of the utility model first back vertical rod place fold locking mechanisms.
Fig. 3 is the scheme drawing of the utility model second back vertical rod place fold locking mechanisms.
The specific embodiment
The utility model has disclosed a kind of folding bicycle 100, as shown in Figure 1, comprising: the driver train 5 that bicycle rack 1, front-wheel 2, trailing wheel 3, vehicle seat 4 and driving trailing wheel rotate.The utility model folding bicycle 100 can be in two states: (1) bicycle state, and at this moment, the bicycle rack 1 of folding bicycle 100, front-wheel 2 and trailing wheel 3 all are opened, and front-wheel 2 is positioned at same plane with trailing wheel 3; (2) folded state, at this moment, related components such as the bicycle rack 1 of folding bicycle 100, front-wheel 2 are accommodated in baggages 6 that are positioned at folding bicycle 100 rears.
The bicycle rack 1 of folding bicycle 100 comprises preceding vertical rod 11, back vertical rod 12, be positioned at before vertical rod 11 tops and connect handled handle connecting rod 13 and connect the intermediate bar 14 of forward and backward vertical rod.The two piece straight-bars 121,122 of back vertical rod 12 described in the utility model for be arrangeding in parallel, baggages 6 are fixed on these two straight-bars 121,122.
In conjunction with Fig. 1, Fig. 2 and shown in Figure 3, fold locking mechanisms of the present utility model is used to lock or unclamp the vehicle frame 1 of folding bicycle, described fold locking mechanisms comprises the key lever 8 that is vertically fixed on the described intermediate bar 14, respectively be provided with a breach 1211,1221 in the described back vertical rod 121,122, described key lever 8 enters or withdraws from described breach 1211,1221 movably.
Described fold locking mechanisms also comprises a locking piece 1212 and controls the button 9 of this locking piece 1212 that described locking piece 1212 prevents that key lever 8 from withdrawing from from described breach 1211.In this preferred embodiment, described locking piece 1212 is one to have the dead bolt of wedge surface.Described dead bolt 1212 is slidably disposed in the first back vertical rod 121, and the bottom butt of described dead bolt 1212 has a spring 1213, and the other end of described spring 1213 is against in the first back vertical rod 121.And be provided with projection 1222 in the breach of the described second back vertical rod 122.
When folding bicycle when the bicycle state exchange becomes folded state, need press the button 9, drive dead bolt 1212 downward compression springs 1213, dead bolt 1212 is accommodated in the first back vertical rod 121, thereby key lever 8 is withdrawed from from described breach 1211, and key lever 8 also withdraws from from the breach 1221 of the second back vertical rod 122 of opposite side simultaneously.Like this, folding again other vehicle frame part just can all be accommodated described baggages 6 to preceding vertical rod 11, handle connecting rod 13, intermediate bar 14 and the rotation section 7 that is positioned at the rear end of described intermediate bar 14, thereby be made folding bicycle convert folded state to.
When folding bicycle when folded state converts the bicycle state to, in baggages 6, pull out vehicle frame, this moment, key lever 8 entered into the breach 1221 of the first back vertical rod 122, because the top of dead bolt 1212 is wedge surfaces, therefore key lever 8 makes dead bolt 1212 simultaneously downward compression springs 1213 in the process that enters, finally make key lever 8 enter into the breach 1221 of the first back vertical rod 122, and dead bolt 1212 is returned to initial position under the effect of spring 1213.Owing to be provided with projection 1222 in the breach 1221 of the second back vertical rod 122 of opposite side, guarantee that key lever 8 can not withdraw from when the bicycle state from the breach 1221 of the second back vertical rod 122.
The utility model available metal, carbon fibre or plastic production are particularly suitable for using the alloy in lightweight material, to alleviate the weight of folding bicycle, are convenient for carrying.Except that above-mentioned preferred embodiment, the utility model still has multiple concrete embodiment.All employings are equal to replacement or equivalent transformation and all technical schemes of forming, all drop within the claimed scope of the utility model.
