Abstract

The utility model relates to a reversion-proof safety cranker for starting and striking fire used in vehicles or other machines, comprising a cranker body with a positioning bolt. A rocker of the cranker body is fixedly provided with a rotating wheel with a ratchet mechanism; the front end of the rotating wheel is provided with a blocking tooth which is matched with a reinforcing jack plate of a bumper. After the reinforcing jack plate of the bumper is fixed on the bumper of an automobile, when the automobile strikes fire and starts, the cranker is inserted in a jack of the bumper. The cranker is rolled, and an inner wheel is driven to rotate by the cranker body. When electricity return phenomenon occurs, because of the function of the ratchet mechanism, the reversion of the cranker is stopped so that people-hurting accidents caused by the reversion of the cranker can be avoided.

Description

The anti-contrarotation security crank

The utility model relates to a kind of vehicle or other machinery uses crank to start the novel anti-contrarotation security crank of sparking usefulness.

When the accumulator electric-quantity that uses when automobile was not enough, the phenomenon that is difficult to start often appearred in motor car engine.This whenever situation takes place, and the driver starts motor car engine with regard to handy crank.When using crank to start, because of produce power-returning phenomenon firing time too early, crank is reversed as motor, fast because of speed reversal, moment is too late to dodge casualty accident will take place.Therefore, existing crank exists hidden danger.

The purpose of this utility model be development a kind of safe, flexibly, anti-contrarotation security crank easily, the generation of the phenomenon of hurting sb.'s feelings when avoiding producing the counter-rotating of power-returning phenomenon crank because of motor.

The technical solution of the utility model is as follows: the anti-contrarotation security crank comprises the crank body of being with positioning bolt.Be characterized in being fixed with the runner that has anti-reverse ratchet mechanism on the inserted link of crank body, the front end of runner has to be reinforced female receptacle with bumper and cooperates and keep off tooth.This reality is made novel employing said structure, can realize its goal of the invention.

During use, bumper of the present utility model is reinforced jack place on the bumper that female receptacle is fixed on automobile, and then the inserted link of crank of the present utility model inserted the jack of bumper, and make the retaining tooth of its runner be stuck in bumper to reinforce female receptacle hole clipping place.Like this, when using the utility model to start up the car, interior wheel rotates under the drive of crank body.When power-returning phenomenon appears in motor car engine, when the crank body produced counter-rotating, interior wheel was desired counter-rotating thereupon, because of ratchet is blocked by ratchet, because the effect of runner retaining tooth has stoped the counter-rotating of this crank, so just can avoid because of the reverse casualty accident of generation of crank.

Below in conjunction with accompanying drawing the utility model is described further:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the assembling schematic representation of each part of the present utility model;

Among the figure, 1 is bumper reinforcing female receptacle, during use it is installed in the jack place of bumper.Positioning bolt 2 usefulness pins 3 are fixed on inserted link 23 front ends of crank body, and 21 is positioning bolt 2 jacks, and 22 is pin 3 jacks.The runner that has anti-reverse ratchet mechanism is to be made of runner shell 5, interior wheel 11, ratchet 17, ratchet 9; Race 10 places of wheel 11 in ratchet 9 is fixed on by spring 8, outside the wheel 11, its ratchet and pawl was formed ratchet mechanism in the internal tooth ratchet 17 of interior dress sand grains 16 was placed in, and two sides are used

baffle plate

7,19 cappings respectively; The runner shell 5 of band retaining tooth 4 be placed in and be fixed on ratchet 17 outer constitute prevent the runner that reverses.14 is packing ring, and 15 is ratchet 17 internal tooths, is shaped as slope shape.18 is the seaming of ratchet 17, is meshed with the recess 6 of runner shell 5.In wheel

fixed hole

12,24 to be arranged on 11 be the fixed hole of inserted link 23, interior wheel 11 is to rotate with the crank body with fixed hole 24 places that bolt 13 is fixed on inserted link 23 afterbodys.Crank body of the present utility model by inserted link 23, curved 25, handle 29 adopts the connections of socket types to constitute; Curved is 25 2 ends square opening, and an end is placed in the square button place of inserted link 23 ends and uses nut 27 and plunger end spiral marking connection, and the square button place that its other end is placed in handle 29 ends connects with nut 27 and handle 29 end thread.26 is packing ring.Curved 25 and the junction of inserted link 23 spring 20 is housed, to adjust its flexible distance.Crank body of the present utility model is that the socket type connects, and disassembly and assembly voluntarily are with handle sleeve 28 on handle 29, and it can reduce the frictional force that handle produces when rotated with the shaking and rotate of crank.The utility model dismounting runner down is exactly existing common crank, and installing runner is exactly the anti-contrarotation security crank.The utility model also can be applicable to the machinery of other crank type sparking starting.

Claims
