Embodiment Construction
[0004] attached figure 1 It is a structural schematic diagram of the two-way overriding mechanism of the present invention.
[0005] attached figure 2 It is a structural schematic diagram of the two-way override starting handle of the present invention.
[0006] attached image 3 It is a structural schematic diagram of Embodiment 2 of the present invention.
[0007] figure 1 Among them, the two-way overriding mechanism of the present invention is a ratchet meshing and roller extrusion mechanism. When the outer ring 9 of the one-way device is rotated clockwise, the outer ring 9 of the one-way device and the spring 10 squeeze the roller 7 to hold the transmission shaft 2 tightly. And drive the transmission shaft 2 to rotate the starting shaft of the internal combustion engine. After the internal combustion engine starts, the transmission shaft 2 and the internal combustion engine starting shaft will naturally surpass the clutch. At the wider part of the road, the transmiss...

The invention relates to a two-way surpassing starting handle relating to the technical field of internal-combustion engine handle starting and mainly comprising a transmission shaft, a one-way device outer ring, a ratchet ring, a movable pawl and a handle, wherein the ratchet ring is externally provided with a convex pin; the circumference of the one-way device outer ring is provided with a groove which is internally provided with the movable pawl, the lateral surface of the one-way device outer ring is provided with a roller path which is internally provided with a rolling column and a pressure spring, wherein the rolling column is rotationally matched with the movable pawl, the one-way device outer ring is rotationally matched with the ratchet ring and the transmission shaft, and the handle is fixedly connected with the one-way device outer ring; and the convex pin arranged on the ratchet ring is matched with a jacket arranged on a gear chamber cover of an internal-combustion engine. When the handle is rotated, the one-way device outer ring extrudes the rolling column to clasp the transmission shaft and drive the transmission shaft to rotate a starting shaft of the internal-combustion engine, after the internal-combustion engine is started, the transmission shaft naturally surpasses a clutch, if the internal-combustion engine reversely rotates, the movable pawl pushes the rolling column to a wider position of the roller path under the action of the ratchet ring, then the transmission shaft is separated from the one-way device outer ring, and the handle stops reversely rotating, therefore, injury accidents are prevented.
Description
technical field [0001] The invention relates to the technical field of internal combustion engines, specifically to the technical field of manual starting of internal combustion engines, and the international classification number is F02N 1 / 02. Background technique [0002] Known internal-combustion engine is easy to start reverse when starting with the handle at present, causes the handle to reverse with the starting shaft, causing personal injury accidents, and this problem has not been solved so far. Contents of the invention [0003] In order to eliminate potential safety hazards when the handle of the internal combustion engine is started, the present invention proposes a two-way overriding starter handle, which mainly consists of a transmission shaft, a one-way device outer ring, a ratchet ring, a movable pawl, and a handle. There are protruding pins on the outside of the ratchet ring, grooves are opened on the circumference of the outer ring of the one-way device, a...
