Description

Double driving bicycle

The utility model relates to a kind of bicycle, especially double driving bicycle.

At present, the employed bicycle of people all is that pin is stepped on the driving bicycle.This class bicycle type of drive is single, just can't start once the pin step on device is malfunctioning, makes troubles for the people that goes out to drive a vehicle.

The purpose of this utility model provides a kind of double driving bicycle, increases the hand-drive function under the prerequisite that keeps the foot-on device, reaches two purposes that drive.

The purpose of this utility model is achieved in that the structure that changes handgrip in the bicycle that comprises vehicle frame, steel rope, handgrip, brake handle, front-wheel, trailing wheel, foot pedal apparatus, seat cushion, and hand driving device is installed.Its structural feature is: sprocket wheel is installed on handgrip, and handgrip is connected with front-wheel with chain by sprocket wheel; Handgrip is divided into driving lever and follower lever, and pipe link and spring are housed in driving lever, and driving lever is stretched out at pipe link two, on the pipe link of driving lever afterbody contiguous block is installed, and the through hole locking piece is housed on the driving lever outer wall, is set with fix shaft on the locking piece; Be set with locating dowel pin and little spring on the fix shaft, its afterbody is equipped with locked cock; Driving lever is connected with driven member by contiguous block, is set with locating bush on driving lever and follower lever, is set with sleeve between two locating bushs, and sleeve is welded on the vehicle frame.

The utility model can make the sprocket wheel rotation by rotating driving lever and follower lever, and sprocket wheel drives front-wheel by chain and rotates, and advances thereby drive bicycle.

Adopt such scheme, compact conformation, easy to use, drive flexibly, both fit wellly step on driving, but also driven by shaking has been expanded the bicycle driving mode, and has been had the effect of body-building concurrently.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is integral structure figure of the present utility model;

Fig. 2 is the component diagram of Fig. 1, and it mainly is the constructional drawing of hand driving device part;

Fig. 3 is the A-A cutaway view of Fig. 2;

Fig. 4 is the B-B cutaway view of Fig. 2;

Fig. 5 is the C-C cutaway view of Fig. 2.

As seen from Figure 1, Figure 2: the utility model is made up of vehicle frame 14, steel rope 17, handgrip 23, locking handle 18, front-wheel 19, trailing wheel 21, foot pedal apparatus 20, seat cushion 22, sprocket wheel 10, chain 11 etc., their annexation and architectural feature are: sprocket wheel 10 is installed on handgrip 23, and handgrip 23 is connected with front-wheel 19 with chain 11 by sprocket wheel 10; Handgrip 23 is divided into driving lever 1 and follower lever 12, pipe link 16 and spring 15 are housed in driving lever 1, driving lever 1 is stretched out at pipe link 16 two, on the pipe link 16 of driving lever 1 afterbody, contiguous block 8 is installed, on driving lever 1 outer wall, through hole locking piece 4 is housed, be set with fix shaft 2 on the locking piece 4, be set with locating dowel pin 3 and little spring 5 on the fix shaft 2, its afterbody is equipped with locked cock 6; Driving lever 1 is connected with driven member 12 by contiguous block 8, is set with locating bush 7 on driving lever 1 and follower lever 12, is set with sleeve 9 between two locating bushs 7, and sleeve 9 is welded on the vehicle frame 14.

As can be seen from Figure 2: do not hold at the follower lever 12 that links to each other with driving lever 1 to have the groove that adapts with contiguous block 8.

As shown in Figure 4: be distributed with the knock hole 24 that adapts with locked cock 6 in the side of the locating bush 7 that is connected with fix shaft 2.

As shown in Figure 5: the central through hole of locking piece 4 is a cross-hole.

The utility model can realize that pin drives and two kinds of functions of hand-drive.Wherein pin drives and follows known technology the same, here repeats no more; Hand-drive is finished like this:

One. start

1. pulling fix shaft 2, make on the fix shaft 2 locating dowel pin 3 protruding locking pieces 4 and with locking piece 4 on cross-hole not on same plane, fix shaft 2 and locked cock 6 broke away from locating bushs 7 and moved no longer inwards this moment.

2. be pulled outwardly the bar 16 that is dynamically connected, contiguous block 8 breaks away from follower lever 12, pulls driving lever 1, makes driving lever 1 and follower lever 12 not in same orientation, and becomes 180 °; Decontrol pipe link 16 then, at spring 15 effect lower connecting rod 16 and contiguous block 8 rapid returns, contiguous block 8 inserts in the groove of follower lever 12, and driving lever 1 is connected with follower lever 12; One holds driving lever 1, and another holds follower lever 12, makes circumference respectively and rotates, and handgrip 23 rotates, and the sprocket wheel 10 on the handgrip 23 rotates thereupon, and sprocket wheel 10 reaches bicycle front-wheel 19 by chain 11 with power, and bicycle front-wheel 19 obtains power and rotates.

Two. the location

1. be pulled outwardly the bar 16 that is dynamically connected, contiguous block 8 breaks away from follower lever 12; Rotate driving lever 1, making driving lever 1 and follower lever 12 is on the same direction in same orientation, decontrols pipe link 16 again, and contiguous block 8 is rapid return under spring 15 effects, and contiguous block 8 enters the groove interior (as shown in Figure 2) of follower lever 12.

2. pulling fix shaft 2 makes the locating dowel pin 3 on the fix shaft 2 parallel with locking piece 4, fix shaft 2 rapid returns under the effect of little spring 5, and locked cock 6 inserts in the knock hole 24 of locating bush 7, has promptly realized the location.

Three. brake

Brake modes of the present utility model is identical with the brake modes of existing bicycle, only need pull brake handle 18, can realize brake by steel rope 17.
