Problems solved by technology

[0002] The rope-drawn engine uses a rope to start the work. When the rope pulls the rope to rotate, it drives the engine to start through the transmission mechanism. In the existing design, there is no vent on the air guide cover, so that the rope will In the process, since the air guide cover is closed, the air in it cannot circulate with the outside world, which will produce a certain resistance to the pull rope, which will bring inconvenience to the pull rope and affect the starting of the engine.

Abstract

The invention relates to the technical field of support equipment of engines, in particular to an air director for a pull rope type engine. The air director comprises a disc-shaped outer disk with a containing cavity, a disk drawing shaft for mounting a pull rope disk is arranged at the bottom of the containing cavity, a through hole is formed in the side wall of the containing cavity of the outer disk, a pull rope penetrates the through hole, a bottom ventilation opening is formed in the bottom of the containing cavity of the outer disk, an outer wall ventilation opening is formed in the outer wall of the outer disk, so that air in the air director and outside air can be circulated in real time, resistance on the pull rope is avoided in the rope drawing process, and smooth work of the pull rope is ensured.

Description

technical field [0001] The invention relates to the technical field of supporting equipment for engines, in particular to a wind guide cover for a pull-cord type engine. Background technique [0002] The rope-drawn engine uses a rope to start the work. When the rope pulls the rope to rotate, it drives the engine to start through the transmission mechanism. In the existing design, there is no vent on the air guide cover, so that the rope will In the process, since the air guide cover is closed, the air therein cannot circulate with the outside world, which will generate certain resistance to the stay rope, which will cause inconvenience to the stay rope and affect the starting of the engine. Contents of the invention [0003] In view of the above technical problems, the present invention provides a wind guide cover for a pull-cord type engine, which is provided with an air vent, and the gas in the wind guide cover can communicate with the outside air, so that the pull rope ...
