Abstract

The utility model belongs to a starting device for a vehicle, which is a safety vehicle initiator driven by manpower. The primary structure is that a cranking bar is arranged in a casing; the cranking bar is divided into two sections; a combination device of obverse rotation and a disengagement combination device of reverse rotation are arranged on the cranking bar. When the vehicle is started by manpower, the combination of two sections of cranking bar can be automatically disengaged under the condition of the sudden reverse rotation; the part holding by hand of the cranking bar can not reversely rotate concomitantly; the accident of injury of people caused by the reverse rotation of the cranking bar can be prevented. The utility model has simple structure, small volume (the volume is only the same as the volume of a fist), convenient operation and safety.

Description

Safety vehicle initiator driven by manpower

The utility model belongs to the vehicle starting device, is a kind of automotive safety hand-operated starter.

At present, various automobiles generally use hand starting under the situation of starter motor conk-out.Because common hand-operated starter does not have safety installations, it is excessive to work as ignition advance angle during hand starting, reversing appears in motor when (premature ignition), motor drive this moment crank reverses fast, because speed is fast, strength is big, is difficult to control injure people's accident of therefore crank and occurs repeatedly, and real is handling safety hidden danger.

The present utility model purpose is to provide a kind of hand-operated starter of safety type, can prevent effectively that crank from reversing the people's that injures accident generation.

The utility model is to realize like this.

In a housing, crank is housed, two parts about separated being divided in the crank, has left engagement pawl on the crank, right engagement pawl, left and right sides engagement pawl has left tooth embedding outward, two-way tooth embedding, right tooth embedding, tooth embedding both sides have left spring and right spring respectively, and left engagement pawl is fixed as one with pin and crank, the pin head stretches out partly and links for key and left tooth embedding keyway, left tooth embedding can be endwisely slipped on left engagement pawl, and right engagement pawl is connected with the crank right part and can endwisely slips on crank with key, is connected and can endwisely slips with key between right tooth embedding and housing, the housing left side has locking-type plug, and the crank front end has twist pin.

During work, crank is inserted on the bumper in the crank way to motor, simultaneously locking-type plug is inserted together in crank way both sides lateral opening, housing is fixed on the bumper, positive hour hands shake crank just can make vehicle starting, if rocking-turn motor generation premature ignition, motor produces suddenly and reverses when driving the crank reverse, a cover that drives in the housing is thrown off the work of interlock mechanism, two engagement pawls are thrown off interlocking pattern about making, make the crank right part not continue together to execute commentaries on classics, take place thereby finish the accident of avoiding crank to hurt sb.'s feelings.

The utility model has following advantage compared with the prior art:

One, now generally use the anti-reversing gearbox of common hand-operated starter, therefore operate dangerously, use of the present utility model can prevent effectively that crank from reversing the unsafe problems of hurting sb.'s feelings.

Two, the utility model is simple in structure, volume is little, and (having only the fist size) is in light weight, and cost is low, is easy to promote.

Three, the design of the utility model locking-type plug utilizes the lateral opening of crank way both sides on the bumper, does not need any transformation and increases device.

Four, flexible operation, easy to use

The utility model concrete structure and embodiment are provided by the following drawings:

Fig. 1, be that the utility model general structure is cutd open and shown schematic representation

Fig. 2, be that the utility model housing cuts open and shows and tooth embedding schematic representation directly perceived

Fig. 3, be that the embedding of the utility model housing tooth is cutd open and shown and engagement pawl schematic representation directly perceived

Fig. 4, be that the utility model Fig. 2 A-A cuts open and shows schematic representation

Fig. 5, be that the utility model Fig. 2 B-B cuts open and shows schematic representation

Fig. 6, be that the A of the utility model Fig. 2 is to schematic representation

Below in conjunction with accompanying drawing to further auspicious the stating of the utility model concrete structure and embodiment

Shown in accompanying drawing:

Crank left part 13 is housed in housing 1, crank right part 12, about two ones be off state, can execute commentaries on classics.

Left engagement pawl 4 is housed on crank left part 13, on left engagement pawl 4, be with left tooth embedding 3, left side pin key 6 passes crank left part 13 and is fixed with left engagement pawl 4 and is one, pin key 6 two, a left side pass keyway for of bonding and left tooth embedding 3 endoporus and link and make left tooth embedding 3 rotate the whiles with left engagement pawl 4 to endwisely slip, on the engagement pawl 4 of a left side left spring 2 is arranged, right-hand member withstands on the left side of left tooth embedding 3.

On crank right part 12, be with right engagement pawl 8, right pin key 9 passes the keyway that stretches out for key and right engagement pawl 8 endoporus at crank two and links, making right engagement pawl 8 rotate with crank can endwisely slip simultaneously, there is key to make right tooth embedding can not rotate and to endwisely slip being with on the right engagement pawl 8 between right tooth embedding 7 it and the housing 1, on right engagement pawl 8 right sides right spring 10 is arranged, in the middle of left tooth embedding 3 and right tooth embedding 7, two-way tooth embedding 5 is housed, can radially rotate with axle and ask slip, the left side of housing 1 is provided with fixedly skewer head 14, during work, crank is inserted in the crank way to motor, fixedly skewer head 14 inserts simultaneously in crank way both sides lateral opening housing 1 is fixed on the bumper simultaneously, positive hour hands are to shaking crank, crank right part 12 drives right engagement pawl 8 by right pin key 9 and rotates, because the elastic force effect of right spring 10 makes right engagement pawl 8 move right interlock left side knot pawl 4 and rotates (referring to Fig. 3) simultaneously, left side engagement pawl 4 and the 13 left tooth embeddings 3 of crank left part have left pin key 6 to link and together rotation, this moment is owing to right spring 10 design elasticity rate left springs 2 are twice, and right tooth embedding 7 can not be rotated under the restriction of key 17, blocking two-way tooth embedding 5 simultaneously can not rotate, rotation makes inclined-plane between left tooth embedding 3 and two-way tooth embedding produce end thrust left and compresses the interlocking pattern (referring to Fig. 2) deviate from behind the left spring 2 with two-way tooth embedding, thereby the positive hour hands of crank left part are rotated until the rocking-turn motor.

When if crank left part 13 reverses suddenly, drive left engagement pawl 4 and left tooth embedding 3 reverses together, left side tooth embedding 3 is because the left side tooth of the two-way tooth embedding 5 of its tooth interlock of promotion of left spring 2 also reverses it together, the tooth of two-way tooth embedding 5 is embedded in the right tooth embedding 7, right tooth embedding 7 can not radially be rotated and can only move axially owing to there being key 17 to connect with housing 1, because two-way tooth embedding 5 is rotated and the ramp effect generation end thrust of tooth makes the right engagement pawl 8 of right tooth embedding 7 promotions move right simultaneously, the interlocking pattern of throwing off left engagement pawl 4 and right engagement pawl 8, crank right part 12 is not rotated simultaneously with crank left part 13, thereby finish the anti-reverse journey that turns over.

The left spring 2 of design is littler than right spring 10 elastic force, can not promote the disengagement that moves to right of whole disengagement interlock mechanism by the thrust of left spring 2, the strength that makes its disengagement mainly is that to drive the thrust that two-way tooth embedding 5 produces by left tooth embedding 3 rotation radial forces more much bigger than the elastic force of right spring 10, therefore can throw off.
