Abstract

The utility model relates to a hand starting safety device for an automobile. A base is fixed on the position which is inserted with a cranking bar of the bumper of the automobile through a fastening piece; a rotatable ratchet wheel and a pawl matching with the star wheel are arranged on the base; a hole matching with the insertion of a hand cranking bar for starting is arranged in the center of a ratchet wheel. When the hand cranking bar is used for starting, the cranking bar is rebounded when the ignition of the automotive engine is premature; the reversion of the ratchet wheel can be stopped by the pawl; the rebound of the hand cranking bar can be controlled; the personal safety of drivers can be effectively protected.

Description

Hand starting safety device for automobile

The utility model relates to a kind of automobile hand starting safety device.

Motor car engine is generally all used motor starting, but in cold season, starting torque increases, for the ease of starting, sometimes must be by hand crank, at this moment the lateral pin of the hand crank of starting termination is embedded in the starting dog of engine crankshaft front end, with the manpower turning crankshaft, start, but because motor is lighted a fire too early sometimes, the direction of gas pressure effect is opposite with the moving direction of piston, tend to occur hand crank counter-rotating, the driver to such an extent as to injure when fiercely rebounding, What is more kills the people, very dangerous.

The utility model provides a kind of when using hand crank to start at the problem of above-mentioned existence, and the hand starting safety device of control handle bounce-back can be protected driver's personal safety effectively.

This hand starting safety device has a pedestal, one rotating ratchet is installed on the pedestal, there is the hole that cooperates with starting handle setting-in at the center of ratchet, is fixed with the ratchet that cooperates with ratchet on pedestal, and this device is fixed on the position of the hand crank of former insertion on the bumper.

When needs start by hand crank, the hole that hand crank cooperates with hand crank setting-in by the ratchet center, the lateral pin of its termination embeds in the starting dog of engine crankshaft front end, shakes handgrip clockwise, ratchet follows crank to rotate, ratchet does not have resistance to ratchet, because engine ignition is too early, handle will reverse when rebounding, ratchet rotates round about, ratchet is given reaction force of ratchet, stops ratchet to running in the other direction, has also controlled the counter-rotating of hand crank.

This device has been controlled the bounce-back of hand crank, thereby has prevented owing to the crank bounce-back causes driver personnel's casualty accident, has protected driver personnel's safety effectively.

Be an embodiment of the present utility model and embodiment's accompanying drawing below.

Fig. 1 is a plan view of the present utility model.

Fig. 2 is the plan view of Fig. 1.

Fig. 3 is the left side view of Fig. 1.

Fig. 1,2, in 3, (1) is pedestal, (2) be ratchet, there is the hole (3) that cooperates with hand crank setting-in at the center of ratchet (2), between ratchet (2) and the pedestal (1) rolling bearing (4) is housed, ratchet (2) pedestal (1) relatively is rotatable, on pedestal (1), be fixed with the ratchet (5) that cooperates with ratchet (2), one end of ratchet (5) is fixing with pedestal (1) by spring (6) and Xiao Zi (7), ratchet (5) is also fixing by bolt (8) and pedestal (1), control ratchet (5) and ratchet (2) engagement and the cam that separates (9) are installed on pedestal (1), cam (9) is gone up by Xiao Zi (10) stationary cam operation handlebar (11), (12) be cap, the last capping of cap (12) is installed by rolling bearing (13) and ratchet (2), and the bottom of cap (12) is fixing by screw (14) and pedestal (1).(15), (16) be bolt, nut fastening piece, by bolt, nut fastening piece (15), (16) this device is fixed on the position that former handle inserts on the bumper.

Claims

1, a kind of automobile hand starting safety device, it is characterized in that having a pedestal (1), pedestal (1) is gone up a rotating ratchet (2) is installed, and there is the hole (3) that cooperates with starting handle setting-in at the center of ratchet (2), is fixed with the ratchet (5) that cooperates with ratchet (2) on pedestal (1).This device is fixed on the position that crank inserts on the bumper by fastening piece.
