Two-way rotation control mechanism for ratchet of gasoline and diesel engine starting device

Abstract

The invention relates to a safety mechanism of a gasoline-diesel engine starting device, in particular to a bidirectional rotation control mechanism for the ratchet of the gasoline-diesel engine starting device. The bidirectional rotation control mechanism comprises the shell of the starting device, the ratchet and a pawl, wherein the ratchet is mounted on the shell through a ratchet shaft, the pawl is mounted on a sleeve through a pawl shaft penetrating the sleeve, a spring II is disposed between the pawl and the shell, and the pawl swing along the pawl shaft under external force; a reset control mechanism is disposed below the middle of the pawl. By the bidirectional rotation control mechanism, potential safety hazard during ratchet bidirectional rotation control is eliminated effectively, and safety is increased.

Description

technical field [0001] The invention relates to a safety mechanism of a starting device for a gasoline and diesel engine, in particular to a bidirectional rotation control mechanism for a ratchet wheel of a starting device for a gasoline and diesel engine that eliminates potential safety hazards and improves safety. Background technique [0002] Existing gasoline and diesel engines (people habitually refer to gasoline engines and diesel engines as gasoline and diesel engines) are started by means of a starting device. [0003] Chinese patent 2014202063458 discloses a manual starter device for small gasoline engines and small diesel engines, which effectively solves the time-consuming and laborious startup problems of manual starters, electric starters and hand starters in the existing market, and the inability to automatically find the start point However, the engine is damaged greatly, the use cost is high, the service life is short, the starting operation is unsafe and mai...

Problems solved by technology

[0003] Chinese patent 2014202063458 discloses a manual starter device for small gasoline engines and small diesel engines, which effectively solves the time-consuming and laborious startup problems of manual starters, electric starters and hand starters in the existing market, and the inability to automatically find the start point However, there are technical problems such as large damage to the engine, high use cost, short service life, unsafe start-up operation and difficult and unsafe maintenance.

However, in actual use, when looking for the starting point of the engine, it is necessary to manually pull the control block of the pawl, and manually reset the control block after finding the starting point of the engine. According to the strict operation process, there will be no Safety issue; however, if a worker forgets to reset the control block, there will be a safety hazard that could damage the engine starter or the engine

[0004] In summary, there are potential safety hazards in the hand-operated starting devices for small gasoline engines and small diesel engines of the prior art, and the safety is low.
