Detailed Description

The following describes the present invention in further detail with reference to the accompanying drawings.

A quick-release structure of an electromechanical starting device of a gasoline engine is shown in figures 2 and 3 and comprises a connecting seat 2 and a shell 3, wherein the connecting seat 2 is fixedly arranged at a starting port of the gasoline engine, and the shell 3 is detachably matched on the connecting seat 2. Referring to fig. 5, a starting motor 5 and a power supply 6 for supplying power to the motor 5 are arranged in the housing 3, the motor 5 is connected with a shift fork disc 4 through a speed reducing mechanism, and the shift fork disc 4 is used for driving the gasoline engine to start.

Referring to fig. 4 and 5, in the embodiment, the front section of the connecting base 2 is provided with a mounting hole 2a, and the connecting base 2 is fixed on the gasoline engine through a bolt. The rear end of the connecting seat 2 is provided with an annular flange 2b, and notches 2c are circumferentially distributed on the annular flange 2 b; the setting of 3 front ends of casing is the plug of notch cuttype shape, including big ladder section 3c and little ladder section 3d, sinks in connecting seat 2 rear end face in annular flange 2b to realize the cooperation of big ladder section 3c and the terminal lateral wall of connecting seat 2 rear end, set up seal ring groove 3c1 on big ladder section 3c, in order to realize the sealed cooperation of connecting seat 2 and casing 3. The outer diameter of the small step section 3d is smaller than that of the large step section 3c and is used for being inserted into an inner hole of the annular flange 2b, a clamping block 3e is circumferentially distributed on the small step section 3d, and the size of the clamping block 3e is matched with that of the notch 2 c; after the clamping block 3e passes through the notch 2c and rotates to the inner surface of the annular flange 2b, the relative fixation of the connecting seat 2 and the shell 3 is realized. To improve the ease of assembly, a sloped guide surface 2d is provided on the back of the annular flange 2b, and the guide surface 2d extends toward the notch 2c to facilitate the screwing of the latch 3 e.
