Novel engine recoil starter structure

Abstract

The invention relates to a novel engine recoil starter structure. The novel engine recoil starter structure comprises a starting cover, a base, a starting ratchet, an auxiliary spring, a starting ropewheel, a starting spring, a handle, a base screw and a starting pull rope. Under the structure of the external starting spring, the flexibility of rotation of the starting rope wheel can be met, andit can be guaranteed that the starting spring cannot break down due to unhooking in the working process of an engine. In this way, the problems in a conventional starting structure on the market thatan outer hook of a starting spring pops up when a set gap is large, a rope wheel is not flexible enough to rotate when the set gap is small, and a starting handle cannot be reset smoothly are solved,the failure rate is greatly reduced, equipment maintenance and use are facilitated, time and labor are saved, and the starting structure is more user-friendly.

Description

technical field [0001] The invention relates to the technical field of engine recoil starting, in particular to a novel engine recoil starter structure. Background technique [0002] The small gasoline engine with pull-start is simple in structure and light in weight, and is widely used in hand-held garden tools. The crankshaft started to rotate under the external force of the hand starter to the whole process of the automatic idling of the engine is called the starting process of the engine. A general recoil starter is composed of a starter cover, a return coil spring, a starting handle, a pull rope, and a starting sheave. Can close, flywheel is fixed on the crankshaft. When starting the engine, hold the starter handle tightly and pull the pull rope, the pull rope drives the starter rope wheel to rotate, the starter rope wheel drives the return coil spring to shrink, the claw on the starter rope wheel and the pawl on the flywheel drive the flywheel to rotate, Then the cr...

AI Technical Summary

Problems solved by technology

In order to ensure the flexibility of the moving parts, the fit clearance between the fitting parts should not be too small, if the clearance is too small, the starter spring cannot be reset normally due to the friction between the parts, but it should not be too large, the fit clearance is too large Large, when the engine is working, due to the vibration of the engine, the starting spring will over time start the sheave from the original installation position or the starting cover will come out or the spring will explode, resulting in the failure of the starting function
