Abstract
The utility model relates to a labor-saving device for bicycles, comprising a bicycle body, which is characterized in that: a unidirectional gear is arranged on a bicycle crank; a bearing and a locking device are positioned between a force-bearing frame and an axis; the force-bearing frame is connected with a unidirectional lock blade through a pin of the unidirectional lock blade; a spring is arranged between the force-bearing frame and the unidirectional lock blade; the unidirectional gear is fitted with the unidirectional lock blade. By adopting the structure, the utility model has the advantages of changing the transmission structure for pedals on the cranks, extending the force arm length without altering the size of the original standard piece, saving labor, and enjoying simple structure, functional reliability, and low cost.
Description
Affiliated technical field
The utility model relates to a kind of labour saver for bicycle.
Background technology
Bicycle is a kind of common common vehicle, develops so far, and technology is quite ripe., shortcoming is the not performance fully of effect of the stretcher of existing bicycle, does not reach labour-saving effect the most.
Summary of the invention
The purpose of this utility model provide a kind of can make stepping bicycle more the labour-saving labour saver for bicycle to remedy the deficiency of prior art.
The purpose of this utility model is achieved in that technical scheme: labour saver for bicycle, comprise bicycle body, and it is characterized in that the bicycle cripple is provided with ratchet; Between stressed and the axle bearing and latching device are arranged, go up for stressed and be connected with unidirectional locking plate by unidirectional locking plate pin, stressed is provided with spring with unidirectional locking plate, and unidirectional locking plate and ratchet cooperate.
Good effect of the present utility model is: the utility model has changed the drive mechanism of original bicycle cripple upper footboard because have said structure, under the situation that does not change original gauge member size, has increased the length of the arm of force, has reached the labour-saving effect.The utlity model has in addition simple in structure, functional reliability height, the characteristics that cost is low.
Description of drawings
Below by embodiment, and in conjunction with the accompanying drawings the utility model is further described:
Fig. 1 is the structural representation of embodiment of the present utility model;
Fig. 2 is the partial side view of Fig. 1.
The specific embodiment:
Embodiment:
In the drawings, the 1st, axle, the 3rd, tapered cup nut, the 4th, packing ring, the 5th, block nut, the 6th, stressed, the 7th, screw, the 8th, ratchet, the 9th, unidirectional locking plate, the 10th, unidirectional locking plate pin, the 12nd, cover plate, the 13rd, bicycle cripple.
During use, labour saver for bicycle has increased stressed 6 on original stretcher basis, ratchet 8, unidirectional locking plate 9 and pin 10, spring.Being installed in former stretcher both sides for stressed 6 has increased length, and ratchet 8 is installed in axle 1 front end and fastening.Unidirectional locking plate pin 10 is installed in stressed 6 and tightens.Spring connects stressed 6 and unidirectional locking plate 9.When the cripple is positioned at the dead ahead, labour saver for bicycle is stressed forward the time, by stressed 6, and unidirectional locking plate 9 and sell 10 and pin with ratchet 8 and to make labour saver for bicycle and cripple become an overall growth arm of force, thus laborsaving.When the cripple was positioned at the rear, people's pin was not exerted oneself, ratchet 8 with unidirectional locking plate 9 and sell 10 and do not have locking effect, the cripple separates with labour saver for bicycle, thereby can rotate smoothly.
