Gasoline engine base with underneath-type oil tank

Abstract

The invention discloses a gasoline engine base with an underneath-type oil tank. The gasoline engine base is provided with a base body (1), wherein the base body (1) is in a U shape with a flat bottom, and composed of a bottom plate (1a), a front side plate (1b) and a rear side plate (1c); support lugs (1d) are symmetrically arranged at the left end and the right end of the top of the front side plate (1b); through holes are formed on the support lugs (1d) along a front-and-rear direction; the bottom of the front side plate (1b) is fixedly connected with the front end of the bottom plate (1a), and the rear end of the bottom plate (1a) is fixedly connected with the bottom end of the rear side plate (1c); bosses (1e) are symmetrically arranged at the left end and the right end of the top of the rear side plate (1c), and the bosses (1e) are projected backwards; and assembly holes are formed on the bosses (1e) along an up-and-down direction. The gasoline engine base disclosed by the invention is used for supporting the weight of a whole gasoline engine, is good in support stability and capable of effectively preventing the deformation or the wear of the oil tank, thus effectively prolonging the service life of the oil tank and effectively improving the safety of the oil tank.

Description

technical field [0001] The invention belongs to the technical field of gasoline engines, and in particular relates to a base of an under-tank gasoline engine. Background technique [0002] At present, small gasoline engines such as 139F generally adopt a structure with a lower fuel tank, that is, the fuel tank is located at the bottom of the machine, and the fuel tank supports the weight of the entire machine. Because the fuel tank is a plastic part, its strength is limited, and it is not wear-resistant. The fuel tank is directly in contact with the ground. During long-term use, it is affected by the vibration of the whole machine, and the fuel tank is prone to deformation or wear, and the service life of the fuel tank is short. Once the fuel tank is damaged, it will cause fuel leakage, which not only wastes fuel, pollutes the environment, but also has potential safety hazards such as inflammability and explosion. Simultaneously, the weight of the whole machine is supported...

AI Technical Summary

Problems solved by technology

Since the fuel tank is a plastic part, its strength is limited and it is not wear-resistant. The fuel tank is directly in contact with the ground. During long-term use, it is affected by the vibration of the whole machine, and the fuel tank is prone to deformation or wear, and the service life of the fuel tank is short.

Once the fuel tank is damaged, it will cause fuel leakage, which not only wastes fuel, pollutes the environment, but also poses safety hazards such as inflammability and explosion.

At the same time, the weight of the entire machine is supported by the fuel tank, and the stability is poor
