Abstract

The utility model relates to a hand crank preventing damage caused by reverse rotation, which is used for starting an engine of an automobile or adjusting and repairing the engine of the automobile. The utility model is mainly composed of a hand crank shaft, a crank arm shell, a handle shaft, two ratchet wheels in the crank arm shell and a coupling steel wire. The hand crank overcomes the defect that when the phenomenon of reverse rotation occurs in the engine, the hand crank also generates the reverse rotation for damaging users when an existing hand crank of the automobile is used; the hand crank can also be used for taking a spare tyre of the automobile.

Description

Hand crank preventing damage caused reverse rotation

The utility model relates to a kind of crank, particularly a kind of motor or motor car engine is adjusted, can be prevented when repairing the anti-anti-car Cranking bar for automobile of crank counter-rotating of being used to start-up a car.

Can't pilot engine when the electrical equipment of automobile, mechanical part damage, battery power is not enough or driver, miantainers to motor car engine adjust, when repairing, all need to use Cranking bar for automobile, sometimes also need to utilize manpower to pass through crank drive engine rotation earlier before the vehicle starting in the winter time, pump plays each lubricant housings that lubricant oil removes lubricating engine, with the friction damage that prevents to cause because of the unexpected high-speed starting running of motor, thereby prolong working life of motor without each parts of pump oil lubrication.

The existing motor crank of start-uping a car, generally form by stepped shaft crank axle and taper knob, in engine misses or repairing, adjustment need be piloted engine, driver or miantainers are with in the crank starting process, sometimes because rocket ignition time is too early, make the inflammable mixture premature ignition of Piston Compression, cause engine inversion, thereby also driven the whole crank that is inserted in the engine start pawl in a few percent high speed reverse rotation in second, anti-car phenomenon promptly takes place, the user of service is damaged, by the hand of being injured, the phenomenon of the leg or the face of injuring of injuring happens occasionally, make driver and miantainers' safety can not get ensureing, some senior luxury car is equipped with Cranking bar for automobile for this reason and not, though ensured user's personal safety like this, maybe need keep in repair when motor car engine breaks down, when adjusting motor, the driver, miantainers feel inconvenience again very much because of no crank.

The purpose of this utility model is to overcome the above-mentioned defective of existing Cranking bar for automobile, and a kind of Cranking bar for automobile that in use can resist anti-car is provided, to guarantee user of service's safety.

Anti-the anti-reverse of anti-car crank is achieved through the following technical solutions; Crank is mainly by crank shaft (1); Rocking arm front and rear casing (3); (4) and Handle axis (5) form; Two ends in rocking arm front and rear casing (3) (4) are equipped with respectively two ratchets; Be ratchet (2) and directed handle ratchet wheel (10); The former is fastened on the crank shaft (1); By clockwise ratchet (8) can with rocking arm shell (3); (4) rotate together; Or with crank shaft (1) in rocking arm shell (3); (4) idle running in; The latter is enclosed within on the Handle axis (5); Control ratchet (15) is housed in the Handle axis (5) to be meshed with directed handle ratchet wheel (10); Be fixed with steel wire backguy (21) on the face of the outer garden of directed handle ratchet wheel (10); Steel wire backguy (21) other end links to each other with the clockwise ratchet (8) that inserts ratchet (2); When anti-car phenomenon takes place when; The Handle axis that is held in the hand (5) is by control ratchet (15) the rotational orientation handle ratchet wheel (10) in it; By steel wire backguy (21) counter-rotating ratchet (8) and ratchet (2) are thrown off again; Ratchet (2) and crank shaft (1) are just in rocking arm shell (3); (4) do anti-car idle running with automobile engine in; Rocking arm shell (3); (4) then do not rotate with Handle axis (5), thereby prevented the injured generation of phenomenon of user.

Fig. 1 is the complete section plan view of anti-anti-car crank in the Figure of description;

Fig. 2 is Fig. 1 sectional view;

Fig. 3 is Fig. 2 crank front end enlarged view.

Describe the concrete structure and the working principle of anti-anti-car crank in detail below in conjunction with accompanying drawing.

Work as the driver, when miantainers use crank, earlier the suitable counter-rotating fork on the crank is pulled out clockwise position to (17), by making corotation thimble (11) promote drawing-pressing spring frame (14) along counter-rotating fork (13), force control ratchet (15) to enter the working position that prevents anti-car by work stage clip (28), shake motor with carrying out clockwise direction in the starting dog of crank axle (1) by pawl pin (19) insertion motor car engine then, this moment handle shaft (5), hadle (6), corotation thimble (11), drawing-pressing spring frame (14), control ratchet (15), control ratchet returning pull-spring (27), spring plug (33), control ratchet pressure spring (28), corotation thimble location pellet shot from a slingshot (29) and corotation thimble are located stage clip (30) all around the axis of handle shaft (5), before rocking arm, back cover (3), (4) make the counterclockwise direction corotation, when anti-car takes place in motor car engine, engine crankshaft counter-rotating has suddenly driven clockwise ratchet (8) by crank axle (1) and ratchet (2), before ratchet holder (7) and the rocking arm, back cover (3), (4) counter-rotating simultaneously, but in more than percent seconds zero point, when reverse angle reaches 5 °, be held in the hadle (6) in user's hand, handle shaft (5) and control ratchet (15) wait to center on handle shaft (5) axis with respect to rocking arm before, back cover (3), (4) make the clockwise direction corotation, control ratchet (15) just drives directed internal clickwork (10) and clockwise rotates, by connecting steel wire backguy (21) thereon, clockwise ratchet (8) on the ratchet holder (7) is tightened up, make it to throw off with ratchet (2), ratchet (2) just follows motor car engine before rocking arm with crank axle (1) like this, back cover (3), (4) idle running in, before making rocking arm, back cover (3), (4) and handle shaft (5), hadle (6) is unlikely to and then engine inversion, avoid the generation of the anti-car phenomenon of crank, guaranteed user's safety.

(20) are positioning key among the figure, and (25) are pressure spring, and (26) are rivet, and (22) are the steel wire gate button, and (18) are the thimble protecting cover, and (31) are the protecting cover screw, and (32) are 24 ° of positioning pin holes, and (34) are the fork lateral pin, and (16) are the fork supporting base.

When using this crank inhour to rotate the spare tyre that reaches on the automobile, to pull out backward position along counter-rotating fork (13) earlier, control ratchet (15) is inserted in the directed internal clickwork (10), hadle (6) clockwise direction is rotated 24 °, by control ratchet (15) rotational orientation ratchet (10), clockwise ratchet (8) and ratchet (2) are thrown off, the lock pin (12) that will reverse simultaneously inserts in 24 ° of positioning pin holes (32) to pin directed internal clickwork (10) and clockwise ratchet (8), drive ratchet (2) and crank axle (1) counter-rotating by the counter-rotating ratchet (9) that is pressed in by 3 springs (24) on the ratchet (2) this moment, reaches the spare tyre on the spare wheel moulding bed.

Anti-anti-car crank of the present utility model compared with prior art has the following advantages:

1. owing in this Cranking bar for automobile, be provided with the anti-anti-mechanism of car such as ratchet, ratchet, overcome unsafe defective in the existing Cranking bar for automobile use, ensured driver and maintenance mans' personal safety.

2. make some the senior luxury car that is not equipped with crank because of the Security of worrying existing Cranking bar for automobile, can be equipped with anti-anti-car crank relievedly, be very easy to driver and miantainers.
