Abstract
The utility model discloses a semi-automatic bicycle ladder used for two-wheeled bicycles. A shaft (3) and a clamp (7) are arranged on a fixing frame (4); a fan-shaped chain wheel (5) is installed on one end of the shaft (3); the other end of the shaft is provided with a supporting rod (2); a wheel (1) is installed on the other end of the supporting rod (2); when the utility model is used, the clamp (7) is clamped on two wheels of a bicycle; in the process of riding a bicycle or parking or slowing down, chains are inverted backwards; the wheel (1) falls down; two wheel are added with an auxiliary wheel (equaling to a tricycle); when the bicycle is ridden, the wheel (1) is driven to automatically lift by the chains; when the bicycle is parked at an ending point, the utility model can be used as an ordinary bicycle ladder for use.
Description
The utility model belongs to the Semi-automatic mean providing for stabilised ride using additional wheel that a kind of two-wheel car uses;
Existing two-wheel car ladder has single angle car ladder and two angles car ladder, and these two kinds of car ladders can only use in the terminal point parking;
The purpose of this utility model provides a kind of Semi-automatic mean providing for stabilised ride using additional wheel, and it is made common car ladder and uses when terminal point stops; Automatically rise and fall during temporary term stop midway, make two-wheel car add an auxiliary wheel (being equivalent to three-wheel vehicle);
The purpose of this utility model is achieved in that this Semi-automatic mean providing for stabilised ride using additional wheel comprises wheel, strut bar, axle, fixed mount, fan-shaped sprocket, spring, fixed mount is provided with axle and clamp, one end of axle is installed fan-shaped sprocket, the other end is installed strut bar, the strut bar other end is installed wheel, both ends of the spring is hung on fixed mount and the strut bar, fan-shaped sprocket has long tooth and starts tooth, with clamp Semi-automatic mean providing for stabilised ride using additional wheel is fixed on the two-wheel car, fan-shaped sprocket can mesh with the chain upper inner, this Semi-automatic mean providing for stabilised ride using additional wheel and the same use of common car ladder when terminal point stops, car travel when on the way going slowly in (as bustling highway section) or stopping (as red light time), do not need to get off, this moment is the chain of falling the two-wheel car backward, the top chain is lax, startup tooth on the fan-shaped sprocket and chain engages drive fan-shaped sprocket and rotate, driving axle when long tooth and chain engages rotates, strut bar and wheel fall, and make two-wheel car add a support wheel (being equivalent to three-wheel vehicle), and beginning to overtake, chain transmission forward drives the fan-shaped sprocket rotation, Semi-automatic mean providing for stabilised ride using additional wheel is mentioned, and long tooth separates with chain, and fan-shaped sprocket separates with chain, because the chain in tension started tooth and can not contact with chain this moment.
The utility model has the advantages that: (1) is simple in structure, easy to use, and (2) stop steady, and it is fast to open car, ensures safety relief of traffic.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:
Fig. 1 is that to look scheme drawing Fig. 2 be that to look scheme drawing Fig. 3 be that to start tooth be that the utility model Semi-automatic mean providing for stabilised ride using additional wheel fan-shaped sprocket separates scheme drawing with chain with chain engages scheme drawing Fig. 4 to the utility model Semi-automatic mean providing for stabilised ride using additional wheel for the left side of the utility model Semi-automatic mean providing for stabilised ride using additional wheel to the master of the utility model Semi-automatic mean providing for stabilised ride using additional wheel
This Semi-automatic mean providing for stabilised ride using additional wheel is by Fig. 1 and Fig. 2 as can be known: it comprises wheel (1), strut bar (2), axle (3), fixed mount (4), fan-shaped sprocket (5), spring (6), fixed mount (4) is provided with axle (3) and clamp (7), one end of axle (3) is installed fan-shaped sprocket (5), the other end is installed strut bar (2), strut bar (2) other end is installed wheel (1), spring (6) two ends are hung on fixed mount (4) and the strut bar (2), fan-shaped sprocket (5) has long tooth (8) and starts tooth (9), with clamp (7) Semi-automatic mean providing for stabilised ride using additional wheel is fixed on the two-wheel car, fan-shaped sprocket (5) can mesh with chain (10) upper inner, this Semi-automatic mean providing for stabilised ride using additional wheel and the same use of common car ladder when terminal point stops, car travel when on the way going slowly in (as bustling highway section) or stopping (as red light time), do not need to get off, this moment is the chain of falling the two-wheel car (10) backward, top chain (10) relax (Fig. 3), startup tooth (9) on the fan-shaped sprocket (5) and chain (10) engagement drive fan-shaped sprocket (5) and rotate, driving axle when long tooth (8) meshes with chain (10) rotates, strut bar (2) and wheel (1) fall, make two-wheel car add a support wheel (being equivalent to three-wheel vehicle), beginning to overtake, chain (10) transmission forward drives fan-shaped sprocket (5) rotation, Semi-automatic mean providing for stabilised ride using additional wheel is mentioned, long tooth (8) separates with chain (10), fan-shaped sprocket (5) separates with chain (10), because chain (10) in tension (Fig. 4) started tooth (9) and can not contact with chain (10) this moment.
