Abstract

The utility model relates to a safety cranking bar for starting an automobile, comprising that a cranking bar is divided into a straight bar and a curved bar, and the middle parts of the straight bar and the curved bar are connected through a transmission device; the straight bar of the cranking bar is cranked into an automobile body; the curved bar is rotated by a hand; the straight bar is connected with a driven wheel with a movable jaw; the curved bar is connected with an external tooth ring outside of the driven wheel. When the driven wheel does the single rotation, the movable jaw is engaged with the internal tooth of the external tooth ring; after an engine is started through a hand cranking bar, the rotating speed of the straight bar suddenly accelerates; simultaneously, because the movable jaw can not be engaged with the external tooth ring or free rotate; the curved bar can keep still, which can assure that arms can not be damaged by the curved bar.

Description

Safety cranking bar for starting automobile

The utility model relates to the vehicle starting safety cranking-bar.

Use now the automobile of crank igniting, used crank, all as a whole, when crank is inserted in the car body motor car engine lighted after, motor can drive crank, and rotating speed is accelerated suddenly, at this moment, as crank in time not being extracted out, crank can be injured arm sometimes, so inadequately safely, conveniently.

The purpose of this utility model is that a kind of vehicle starting safety cranking-bar will be provided, and start-ups a car with it, can guarantee personal safety, and is easy to use.

The purpose of this utility model is achieved in that this vehicle starting safety cranking-bar, by the crank that is divided into straight-bar and curved bar two-section, the centre is connected with transmission device and constitutes, the straight-bar of crank inserts in the car body, holding curved bar rotates, straight-bar is connected with the driven wheel that has movable claw, curved bar then is connected with driven wheel external toothing outward, movable claw and external toothing internal tooth match when the unidirectional rotation of driven wheel, and after hand crank was lighted motor, the straight-bar rotating speed was accelerated suddenly, at this moment, because of movable claw can not be again with external toothing mutually interlock rotate freely, it is motionless that curved bar can keep, and guarantees that arm can not injured by curved bar.

The utility model has the advantages that to guarantee personal safety when using, and simple in structure, easy manufacturing.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof:

Fig. 1 is a transmission device internal structure schematic representation.

Fig. 2 is the A-A schematic cross-section.

Fig. 3 is the front cover plan view.

Fig. 4 is the front cover left view.

Fig. 5 is the rear end cover plan view.

Fig. 6 is the rear end cover left view.

Describe in detail below in conjunction with accompanying drawing.

With reference to Fig. 1～6, this vehicle starting safety cranking-bar is made of crank and transmission device, crank divides straight-bar 1 and curved bar 2 two-part, straight-bar 1 can directly be connected with motor mechanism, and 2 of curved bars are to rotate to use handle, curved bar 2 to be connected by transmission device with straight-bar 1; Transmission device is made of the driven wheel 6 in the external toothing 3 that is installed in 4 of front cover 2 and rear end covers, the external toothing 3, in the front cover 1 interior set annulus 9, rolling bearing 8 is installed, rear end cover 4 is provided with the groove of using as 1 one end fulcrums of straight-bar 10, front and rear cover and external toothing 3 fuse by screw 12, and rear end cover 4 welds mutually with curved bar 2; Driven wheel 3 is provided with groove, is provided with the movable tooth 5 with 11 tops of spring in groove, and when driven wheel 3 unidirectional rotations, the sawtooth on movable tooth 5 and external toothing 3 inner edges matches; Straight-bar 1 passes front cover 2, bearing 8 and is connected with driven wheel 6 with screw thread, and inserts in the groove 10 of rear end cover 4.Figure middle (center) bearing 8 is a drive fit with annulus 9, and the two ends of spring 11 then are directly installed in the groove that driven wheel 6 and movable claw 5 establish, and the bottom of movable claw is spherical, so that swing in the set groove of driven wheel 6.

During use, hold Fig. 1 curved bar 7 behind, during the clockwise direction rotation, then external toothing 3 drive movable claws 5 rotate in the same way, make straight-bar 1 rotation, when motor is lighted, driven wheel 6 is still made clockwise direction rapidly and is rotated, at this moment, the movable claw 5 on the driven wheel 6 can not rotate freely with external toothing 3 interlocks again, and the crank that is connected on the external toothing also just keeps motionless.

Claims

1, vehicle starting safety cranking-bar is made of crank and transmission device, it is characterized in that:
