Abstract
The utility model belongs to a power assisted bicycle, in particular to a labor-saving and theftproof bicycle. According to the design proposal provided by the utility model, a front fork is connected on the front end of the frame of the bicycle, the head of the bicycle and a front wheel are connected on the upper end and the lower end of the front fork respectively, a rear wheel is connected on the rear end of the frame, an axle is installed on the lower part of the frame, a sprocket wheel is installed in the middle of the axle, and pedals are connected on the two ends of the axle respectively by cranks. The utility model is characterized in that the length of the crank is smaller than the radius of the sprocket wheel. Because the crank of the bicycle is short, the ride of the bicycle is labor-saving; besides, because the bicycle is provided with an anti-theft alarm device, the problem of being stolen is avoided effectively.
Description
Technical field
The utility model belongs to a kind of walking-replacing tool, and is specifically a kind of not only laborsaving, but also can theft-proof bicycle.
Background technology
Bicycle provides convenience for people's trip, but a stolen big problem that becomes the puzzlement people of bicycle.How could avoid the bicycle of oneself stolen effectively, be that the benevolent see benevolence and the wise see wisdom.The anti-theft appliance of Chu Xianing is of a great variety therefrom, in this numerous anti-theft appliance, reasonable cardinal principle can be divided into two classes, and a class is to pin the lock of headstock, and another kind of is the lock that pins trailing wheel, wherein the former turns to a side to headstock, key is stretched out tapered end and is stuck in outside the head tube, and headstock can't be rotated, and with this headstock is pinned, after but the robber goes home car steathily, with electric drill tapered end is bored several millimeters and just can solve the problem that headstock does not rotate; The lock of a kind of annular of The latter, because one side of something of this lock is a hollow tubular, the robber just can steal to after cutting off hollow tubular at the scene of stopping with car.Therefore all there is problem such as easy destruction in these two kinds of locks and does not have antitheft effect.In addition, existing bicycle all compares hard when riding.
Summary of the invention
The purpose of this utility model is a kind of morpet of design, and is because the crank of this bicycle is shorter, in the process of riding, more laborsaving; Because this bicycle has been installed antitheft alarm system, can avoid stolen problem effectively simultaneously.
According to design plan provided by the utility model, front end at vehicle frame connects front fork, upper/lower terminal at front fork connects headstock and front-wheel respectively, rear end at vehicle frame connects trailing wheel, axletree is installed in bottom at vehicle frame, sprocket wheel is installed at middle part at axletree, utilizes the crank connecting link step respectively at the two ends of axletree, and it is characterized in that: the length of crank is less than the radius of sprocket wheel.
Anti-joyride device is installed on headstock, in the shell of anti-joyride device lock body is arranged, driving lever is arranged on the lock body, hammer is arranged below lock body, the pronunciation rod is arranged below hammer, hammer utilizes bearing pin to be articulated on the shell.
The utility model has the advantages that: because the crank length of this car is less than the radius of sprocket wheel, when bicycle was in the cruising state, the rider was when scrunching pin, and the motion amplitude of its foot is smaller, original little of therefore used force rate.After being provided with anti-joyride device on the headstock, the microvibration that the robber produces when the stealing bicycle can cause that all anti-joyride device sends chimes of doom, reminds passerby to arrest the thief.
Description of drawings
Fig. 1 is bicycle structure figure.
Fig. 2 is the anti-joyride device constructional drawing.
The specific embodiment
As shown in the figure: the front end at vehicle frame 7 connects front fork 2, upper/lower terminal at front fork 2 connects headstock 3 and front-wheel 1 respectively, rear end at vehicle frame 7 connects trailing wheel 6, axletree is installed in bottom at vehicle frame 7, sprocket wheel 11 is installed at middle part at axletree, utilize crank 10 to connect step 9 respectively at the two ends of axletree, the length of crank 10 is less than the radius of sprocket wheel 11.In the time of by bike, the people is sitting on the saddle 5, and two pin constantly scrunch pin 9, and sprocket wheel 11 is rotated, and drives trailing wheel 6 by chain 8 and rotates, and drives bicycle and advances.Behind the contraction in length with crank, although may be harder than original long crank in the starting stage, in case behind the cruising, will feel very light, especially when trudging, the advantage of this car be more obvious.
Anti-joyride device 4 is installed on headstock 3, in the shell 12 of anti-joyride device 4 lock body 13 is arranged, driving lever 17 is arranged on the lock body 13, hammer 14 is arranged below lock body 13, pronunciation rod 15 is arranged below hammer 14, hammer 14 utilizes bearing pin 16 to be articulated on the shell 4.Among the figure 5 is saddle.When vibration takes place in bicycle, can cause the shake of hammer 14, the tup of hammering 14 ends into shape is beaten be positioned at following pronunciation rod 15, pronunciation rod 15 is 1 metal bar, can send sound when beaing, and reminds passerby to arrest cartheft.When oneself by bike the time, with key turns lock body 13, make the driving lever 17 on the lock body 13 push down the right-hand member of beating bar, force the left end of hammer stem to clockwise rotate, make tup can't beat pronunciation rod 15, anti-joyride device is locked.
