Abstract
The utility model discloses a bicycle gravity transfer frame, comprises a bicycle frame of the bicycle, a saddle tube and a back axle. The space between the two shifting forks of the back axle of the bicycle frame of the bicycle and the saddle tube is respectively provided with a lever. One end of the lever is connected with the saddle tube by a fastener and the other end of the lever is connected with the front portion of the two shifting fork holes of the back axle of the bicycle frame by a supporting axle of the lever. The supporting axle of the lever is arranged on the bicycle frame with 6 to 8 cm to the front portion of the two shifting fork holes of the back axle. The beneficial effect of the utility model is that the bicycle gravity transfer frame makes use of the saddle tube and the lever respectively provided between the two shifting forks of the back axle of the bicycle frame of the bicycle to enable the rider's weight to be partially converted into the motive power assisting the bicycle to advance. The rider has buoyancy and labor saving in ride.
Description
Technical field
The utility model relates to the structure of cycle frame, particularly a kind of bicycle force of gravity vehicle frame that shifts bicyclist's deadweight.
Background technology
At present, the bicycle that people ride on market all adopts traditional body frame structure for automotive, though various informative, all be vehicle frame to be linked together, and be connected with front and back wheel with the method for welding.Bicyclist's deadweight itself has been a kind of burden when riding, and it has increased the resistance of riding when advancing.When riding, the human weight major part drops on the trailing wheel of car, because trailing wheel is a drive wheel, this just need just can make car move ahead with bigger power.
Summary of the invention
The purpose of this utility model provides a kind of deadweight with bicyclist itself and is converted to the power that auxiliary car moves ahead, and makes bicyclist's labour-saving bicycle force of gravity vehicle frame more.
To achieve these goals, the technical solution adopted in the utility model provides a kind of bicycle force of gravity vehicle frame, include cycle frame, seatpillar and rear axle, wherein: between two rear axle shift forks of seatpillar and cycle frame, be respectively arranged with lever, one end of lever is connected with seatpillar by clip, and the other end of lever is connected the front portion in two rear axle shift fork holes of vehicle frame by the lever pivot shaft.
Described lever pivot shaft is located on the vehicle frame at the anterior 6-8cm place in two rear axle shift fork holes.
Effect of the present utility model is the lever of this bicycle force of gravity vehicle frame by being provided with respectively between the two rear axle shift forks of seatpillar and cycle frame, make bicyclist's a deadweight part itself be converted to the power that auxiliary car moves ahead, the bicyclist is brisk and laborsaving when riding.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is for connecting the partial enlarged drawing of lever segment.
Among the figure:
1, seatpillar 2, clip 3, lever
4, lever pivot shaft 5, rear axle shift fork 6, vehicle frame
The specific embodiment
Reaching embodiment in conjunction with the accompanying drawings is illustrated bicycle force of gravity vehicle frame of the present utility model.
As shown in Figure 1, 2, the structure of bicycle force of gravity vehicle frame of the present utility model is for including cycle frame, seatpillar and rear axle, between two rear axle shift forks 5 of seatpillar 1 and cycle frame, be respectively arranged with lever 3, one end of lever 3 is connected with seatpillar 1 by clip 2, the other end of lever 3 is fastened on the front portion in two rear axle shift fork holes of vehicle frame by lever pivot shaft 4, and lever pivot shaft 4 is located on the vehicle frame at the anterior 6-8cm place in two rear axle shift fork holes.
Bicycle force of gravity vehicle frame of the present utility model is achieved in that at first the saddle tube with bicycle unclamps, and makes it up and down can be movable, then with saddle tube and clip 2 are connected and fixed, and still inserts in the standpipe of vehicle frame.One end of lever 3 is connected with seatpillar 1 by clip 2 respectively, and the other end of lever 3 is fastened on the vehicle frame at anterior 6-8cm place in two rear axle shift fork holes of vehicle frame by lever pivot shaft 4 respectively.When the bicyclist takes car and rides, its weight will directly be depressed into saddle tube, be depressed into lever 3 again by saddle tube, gravity reaches on the vehicle frame 6 by the pivot shaft 4 of lever, by vehicle frame 6 power has been transferred on the front-wheel of bicycle by leverage, thereby the gravity that trailing wheel is born alleviates.And transmit the power of coming that shifts, the angle by the car front fork is captiveed joint with front axle has become a kind of auxiliary power that moves ahead to the weight of this part deadweight of bicyclist just, makes the bicyclist reach not hard labor-saving effect when riding.
Claims (2)
