Abstract
The utility model relates to a riding person driven wheeled vehicle field in operation, transportation mainly is applied to three cars of ordinary bicycle and manpower. The method is characterized in that: the middle section of the adjustable crank 4 is provided with a saw-shaped rack a with a plurality of gears and an elongated slot b; one side of the locking star wheel 5 is provided with a spring 3 and a spring pin 2; the plate spring 7 is fixed in a clamping groove arranged on the adjustable crank 4. The advantages are that: compared with the common bicycle, the bicycle can increase the force by more than 20 percent by adopting the technology; the structure is simple and the cost is low; the full-sealing technology is adopted, so that muddy water on the road is prevented from permeating; the product is durable; the new and old vehicles are installed and used without change. Has popularization value.
Description
The utility model relates to the wheeled car field that the rider in operation, the transportation drives, and is mainly used in ordinary bicycle and manual tricycle.
The Middle axle crank that the wheeled car that present various rider drives uses is fixed, and the cyclist steps on movable property precession power before death as circumference up and down with both feet.But driving force required when travels down changes along with the variation of condition of road surface, and as travelling on smooth road surface, the cyclist can feel relief freely, goes up a slope or against the wind the time, load increases, and will feel in the time of by bike that effort is until the driving difficulty if run into.The fixed type Middle axle crank can't solve and above-mentionedly change and vehicle load strengthens and causes difficult by bike problem because of road conditions.
The purpose of this utility model provides the wheel car Middle axle crank that a kind of scalable telescoping rider drives.It can keep the advantage of original fixed type Middle axle crank, can overcome road conditions again and change the vehicle load increase and can't reach the labour-saving weakness.
The purpose of this utility model is achieved in that
At present, the propulsive effort of the wheel car of riders drivings such as various bicycles or manual tricycle is to lean on cyclist's both feet to step pedal and pass to chain by Middle axle crank and hinge wheel.But the Middle axle crank of this car (being commonly called as pin turns) all is a real bar of fixing, and the power that it passes to chain is exactly the used power of cyclist, then firmly also wants corresponding increase as the load increase of car.According to lever principle, Middle axle crank is long more to be that the arm of force is big more just laborsaving more.The utility model goes out a kind of telescoping crank device that can freely elongate or shorten according to this principle design, adapts to complicated condition of road surface and wind speed to the difficulty that the cyclist brings with this, reaches laborsaving purpose.
The shortening and the elongation of its crank are finished like this:
Crank shortens: under dead ship condition not with a pin, for example left foot turns to bottom dead center position with the pedal on the left side and stops slightly, right crus of diaphragm is stepping under the right pedal of top dead point is exerted oneself slightly simultaneously, right crank promptly shortens, the length that shortens can be according to road conditions by cyclist's free hold, have 5 grades of selections, beating of each grade can obviously be felt by sole.Again left crank is shortened about 2～3 seconds of the control duration of two cranks as a same reason.
Crank elongation: when crank has been reduced to the shortest position, pedal go to top dead point with the homonymy sole to central axis direction with defeating, at this moment lock star-wheel 5 and will rotate counterclockwise about 60 ° of angles, free locking state, adjustable crank 4 is ejected into extreme length by the reaction thrust that is sleeved on the spring 3 on the spring pin 2 with it.Can hear this moment " clickly " one, show that then the crank adjusted puts in place.
Detailed structure of the present utility model is provided by embodiment and accompanying drawing.
Fig. 1 is the utility model monnolithic case structural representation.
Fig. 2 is the utility model inner structure scheme drawing.
Label among the figure is represented respectively: 1. crank socket; 2. spring pin; 3. spring; 4. adjustable crank; 5. locking star-wheel; 6. set pin; 7. leaf spring; 8. seal ring; 9. connecting bore; 10. connecting bore.
Now describe concrete structure of the present utility model in conjunction with the accompanying drawings in detail:
As shown in Figure 1 and Figure 2, it is made up of the connecting bore 9 and 10 at crank socket 1, spring pin 2, spring 3, adjustable crank 4, locking star-wheel 5, set pin 6, leaf spring 7, seal ring 8 and Middle axle crank two ends.It is characterized in that: adjustable crank 4 stage casings are provided with the serriform gear rack a of 5 gears, and have an elongated slot b; One side of locking star-wheel 5 is provided with spring 3 and spring pin 2.Leaf spring 7 is fixed in the draw-in groove that adjustable crank 4 is provided with.
Be with crank socket 1 on the adjustable crank 4, be rectangle; Adjustable crank 4 and crank socket 1 are passed locking star-wheel 5 by set pin 6 and are connected with aperture C on the crank socket 1; Bullet pin 2 is sleeved in the spring 3, and spring 3 is sleeved in the long endoporus d of adjustable crank 4, and the two ends of spring 3 compress mutually with the inwall of the long endoporus d of the inwall of crank socket 1 and adjustable crank 4 respectively.Be provided with sealing shroud 8 in crank socket 1 port.
The hole 9 at Middle axle crank 4 two ends and hole 10 are used to be connected axis, hinge wheel 11 and the pedal in right side and left side, do not change former method of attachment.
The action of this structure is such with effect:
Crank socket 1 is a rectangular steel pipe, adjustable crank 4 slides in this rectangular steel pipe so that adjust crank length, set pin 6 couples together crank socket 1 and adjustable crank 4, is fixed on the crank socket 1, and the sealing shroud 8 of port can prevent that muddy water from immersing from interface.Adjustable crank 4 stage casings are provided with the serriform gear rack a of 5 gears, and have a long slot bore b, allow set pin 6 pass the aperture C that locks on star-wheel 5 and the crank socket 1, and adjustable crank 4 is freely reciprocatingly slided along elongated slot b in crank socket 1.For adjustable crank can effectively be fixed on the desired position, be to slide and can be at the between cog on the adjustable crank 4 at auto lock on the tooth arbitrarily by locking star-wheel 5, leaf spring 7 is fixed in the draw-in groove that adjustable crank is provided with, purpose be by its elastic force compressing locking star-wheel 5 on tooth bar and limit it and freely rotate.
Advantage of the present utility model: 1. adopt and to regulate Middle axle crank and compare with ordinary bicycle The energy reinforcement is greater than 20%; 2. cost simple in structure low (comparing with the speed variable chain wheel car) adopts complete Sealing Technology has prevented that the muddy water on the road from infiltrating, and is durable in use not fragile; 3. can be general Reach on other associated vehicle on logical bicycle and the pedicab and install and use, need not to change former Any position on the car, it is good to promote the use of condition; 4. the length adjustment owing to every crank is easily capable, The cyclist is easy to grasp and adapt to the characteristics of present technique.
