Problems solved by technology

[0002] At present, because the known single-cylinder internal combustion engine has no safety protection measures for manual start, it is easy to cause personal injury accidents when the manual start is reversed. Stop the reverse rotation of the crankshaft after the gas is released, and control the reverse rotation of the crankshaft within a certain angle range
Chinese utility model patent 01277439.1, the safety device for manual start of internal combustion engine has taken the above measures to solve this problem, but its whole set of mechanism adopts the form of four linkages, which is complicated, difficult to install, difficult to adjust, and high in cost , The appearance performance is poor, the important thing is that its locking mechanism is complex, inconvenient to install, difficult to adjust, and the locking performance is unreliable, so there is still the possibility that the reverse angle of the crankshaft cannot be effectively controlled, and there is still the possibility of personal injury accidents

Embodiment 1

[0008] In the figure, the pawl body 5, the opening pawl 7, and the locking pawl 6 form a conjoined pawl. The positional relationship between the opening pawl and the locking pawl is that when the opening pawl is in the position where the valve is fully opened by the decompression shaft, the locking pawl is in the locked state. The position of the ratchet, the ratchet 8 is fixedly fitted on the crankshaft 9, the slideway 12 is arranged on the body 10, the front limiter 11 and the rear limiter 13 are set on the slideway 12, and the two ends of the push rod 3 are respectively connected to the decompression shaft 1 Cooperating decompression handle 2 and conjoined ratchet, buffer spring 4 is arranged between the rear limit block 13 and the conjoined ratchet.

[0009] When the internal combustion engine starts to start, pull the decompression handle 2 to make the decompression shaft 1 rotate, the decompression mechanism is in the decompression position, and the push rod 3 is opened t...

Embodiment 2

[0011] Ratchet 8 also can cooperate with other internal combustion engine gear shafts.

Embodiment 3

[0013] The slideway 12 can be arranged on the gear chamber cover.

Abstract

The safety apparatus of the internal combustion engine is comprised of the wheel, the detent sliding way, shaft, decompress shaft, decompress handle, the detent, starting pawl, lock pawl combine the connective detent, when reversion happening as hand to start the intenal combustion engine, the wheel pushes the connective detent, shaft, decompress handle and decompress shaft act, when opening valve, the expanded air is released from the cylinder to prevent the inertia reversion of the bend shaft. Setting the reverse angle of the handle to a harow range, the bodily injury accident of reversion is totally eliminated.

Description

technical field [0001] The invention relates to the technical field of internal combustion engines, in particular to the technical field of single-cylinder internal combustion engines. Background technique [0002] At present, because the known single-cylinder internal combustion engine has no safety protection measures for manual start, it is easy to cause personal injury accidents when the manual start is reversed. Stop the reverse rotation of the crankshaft after the gas is released, and control the reverse rotation of the crankshaft within a certain angle range. Chinese utility model patent 01277439.1, the safety device for manual start of internal combustion engine has taken the above measures to solve this problem, but its whole set of mechanism adopts the form of four linkages, which is complicated, difficult to install, difficult to adjust, and high in cost , poor appearance performance, the important thing is that its locking mechanism is comple...
