Description
Technical Field
[0001] The utility model relates to the field of engine equipment, in particular to a novel motorcycle engine piston with high combustion efficiency. Background Art
[0002] The original meaning of engine refers to the "mechanical device that generates power", including internal combustion engines (such as gasoline engines, diesel engines, etc.), external combustion engines (such as Stirling engines, steam engines, etc.) and electric motors; among them, internal combustion engines usually convert chemical energy into mechanical energy; the engine can be used as a power generating device, or it can refer to the entire machine including the power device.
[0003] The piston of a motorcycle engine consists of a piston block and a connecting rod. When in use, the connecting rod drives the piston block to move inside the piston cylinder. When used for a long time, the piston and the piston cylinder contact, rub and wear, which can easily cause damage to the piston block. The piston block needs to be replaced in time to ensure the combustion efficiency of the engine. The piston block and the connecting rod are connected by a pin shaft. There is resistance between the pin shaft and the connection point to prevent the pin shaft from detaching. Therefore, a separate disassembly tool is required for disassembly, which makes disassembly time-consuming and labor-intensive, and makes it inconvenient to replace the piston block. Therefore, a device is urgently needed to solve the above problems. Utility Model Content

[0013] 2. When disassembling the present invention, first move the limit rod to squeeze the first spring, then move the movable rod to stretch the second spring, and at the same time, the limit block moves away from the bottom end of the card block, and then release the limit rod. At this time, the first spring drives the limit rod to disengage from the limit hole, and then squeeze the pin shaft to take it out. No additional disassembly tools are required, which greatly facilitates the disassembly work. BRIEF DESCRIPTION OF THE DRAWINGS
