Document Type and Number:
WIPO Patent Application WO/2022/073228
Kind Code:
A1
Abstract:
A petrol engine capable of preventing petrol leakage, comprising a main body (1), a power compartment (2), a base (3), and an output tube (4), the power compartment (2) being arranged on one side inside the main body (1), and a stabilising structure (9) being mounted on the bottom end of the base (3); the externally connecting part of the petrol engine is sealed and reinforced by means of a sealing structure (6); an externally connecting oil delivery pipe (603) is vertically inserted into the top end of an oil injection pipe (5) and then the externally connecting oil delivery pipe (603) is rotated such that a threaded groove on the inner side wall of an outer pipe sleeve (602) connects in a threaded manner to an outer wall thread (601) to slowly fix the outer pipe sleeve (602) to the top end of the outer side wall of the oil injection pipe (5), the bottom end of a sealing ring (604) also being slowly inserted into the inside of the oil injection pipe (5) at the same time; after the rotation of the externally connecting oil delivery pipe (603) is complete, the outer wall thread (601) is firmly secured to the outer pipe sleeve (602), and the sealing ring (604) at the bottom end of the outer side wall of the externally connecting oil delivery pipe (603) is tightly attached to the inner side wall of the oil injection pipe (5) such that the gap between the outer side wall of the externally connecting oil delivery pipe (603) and the inner side wall of the oil injection pipe (5) is blocked, preventing the occurrence of oil petrol leakage.
