Abstract
The invention provides a disengaging safety handle and relates to the technology field of internal-combustion engine handle starting, which consists of a starting shaft, a starting pin, a base, a ratchet mechanism and a handle; wherein, the base is provided with a pushing pin, a ratchet wheel is provided with a chute, and the handle and the ratchet are arranged together. When the handle is used for starting the internal-combustion engine, if starting reverse occurs, the handle and the starting shaft separate under the action of the starting, the ratchet mechanism and the base, thereby eliminating the potential safety hazard during manual starting and avoiding personal injury accidents.
Description
Technical field
Disengaging safety handle of the present invention relates to technical field of internal combustion engines, is specifically related to internal-combustion engine hand primer technical field, and international classification number is F02N1/02.
Background technique
The starting counter-rotating easily takes place in present known internal-combustion engine when using hand lever starting, cause handle to reverse with starting shaft, causes personal injury accidents.This problem does not have so far and is resolved.
Summary of the invention
Potential safety hazard during for elimination internal-combustion engine hand primer, the present invention proposes a kind of disengaging safety handle, mainly form by starting shaft, starting pin, base, distribution, ratchet mechanism, handle, it is characterized in that: internal-combustion engine turns clockwise, and starting shaft and handle are the fit form of overdrive clutch, and the stress surface of starting pin and starting shaft is a lineal shape, base is fixed on the gear chamber cover, distribution is set on the base, and ratchet mechanism and handle are installed together, and on the external member of ratchet mechanism skewed slot are set.When with the hand lever starting internal-combustion engine, handle cooperates with the overdrive clutch form with starting shaft, and the skewed slot on the external member cooperates with distribution on the base, shakes handle, and when internal-combustion engine obtained starting, the handle rotating speed was lower than the starting shaft rotating speed, and handle is released by starting shaft.As produce starting counter-rotating, starting shaft drives the handle counter-rotating, external member drives counter-rotating by inner member, ratchet, because the stress surface of starting shaft and starting pin is a lineal shape, under distribution on the base and the skewed slot effect on the external member, handle is pushed out, and breaks away from starting shaft, potential safety hazard when eliminating hand lever starting has been avoided the generation of handle counter-rotating casualty accident.

Embodiment
Among Fig. 1, ratchet structure among the present invention is a gear teeth meshing formula ratchet mechanism, be installed on the handle 5, on the external member 7 skewed slot be set, between inner member 8 and the external member 7 ratchet 9 is set, inner member 8 rotates simultaneously with handle 5, when handle 5 drove the rotation of inner member 8 clockwise directions, external member 7 is rotation thereupon not, when handle 5 drives inner member 8 inhour rotations, under ratchet 9 effects, external member 7 rotates thereupon.
Among Fig. 2, on the external member 7 skewed slot is set.
Among Fig. 3, base 2 is provided with promotes 6, so that cooperate with skewed slot on the external member 7.
Among Fig. 4, starting pin 4 is set on the starting shaft 3, when internal-combustion engine turned clockwise, the stress surface that starting shaft 3 cooperates with starting pin 4 was a lineal shape, and base 2 is fixed on the gear chamber cover 1, when adopting handle 5 cranking internal combustion engines, triangle skewed slot on the handle 5 cooperates for the overdrive clutch form with starting shaft 3, and the skewed slot on the external member 7 cooperates with distribution 6 on the base 2, when internal-combustion engine obtains starting, starting shaft 3 rotating speeds are released handle 5 greater than handle 5 rotating speeds.When internal-combustion engine produces the starting counter-rotating, starting shaft 3 drives handle 5 counter-rotatings, external member 7 reverses thereupon, because the triangle skewed slot on the starting shaft 3 and the stress surface of starting pin 4 are lineal shape, under the skewed slot effect on distribution on the base 26 and the external member 7, handle 5 breaks away from starting shaft 3 in very little reverse angle, thereby has avoided the generation of personal injury accident.
Ratchet structure among the present invention also can adopt the friction type ratchet structure.
As an alternative, the base among the present invention 2 also can be fixed on the handle bracket.
As replacement of the present invention, among Fig. 5, be provided with on the external member 7 and promote 6.
As replacement of the present invention, among Fig. 6, on the base 2 skewed slot is set.
Among the embodiment 2, when internal-combustion engine produced the starting counter-rotating, under 6 effects of the distribution on skewed slot on the base 2 and the external member 7, handle 5 separated with starting shaft 3.
