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

Embodiment Construction

[0016] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0017] Such as figure 1 , figure 2 , image 3 with Figure 4 Shown, the present invention is made of base 1, fuel tank 2, pull plate 3 and crankcase 4 etc. Wherein, the base 1 is integrally formed by injection molding, and the material is preferably PP plastic. The base 1 is in the shape of a flat bottom "U" and is composed of a bottom plate 1a, a front side plate 1b and a rear side plate 1c. One. There is an included angle of 110-120° between the front side panel 1b and the bottom panel 1a, and the specific size of the included angle can be determined according to actual needs. The left and right ends of the top of the front side plate 1b are symmetrically provided with lugs 1d, the lugs 1d are arranged in the vertical direction, the bottom of the lugs 1d is integrated with the top of the front side plate 1b, each lug 1d Via holes are opened along th...

Abstract

The invention discloses a petrol engine with an underneath type oil tank. A base (1) is used for wrapping an oil tank (2), and consists of a bottom plate (1a), a front side plate (1b) and a back side plate (1c); a screw inserted from front to back passes through a via hole on a front side plate support lug (1d), an installation hole on a pull disk positioning stage (31) and an assembly hole on an oil tank positioning block (21) for fixedly connecting the front side plate support lug (1d), the pull disk positioning stage (31) and the oil tank positioning block (21) together; and a screw inserted from bottom to top passes through an assembly hole on a back side plate boss (1e) and a via hole on an oil tank platform (22) and extends into an installation hole of a crankcase positioning rod (41) for fixedly connecting the back side plate boss (1e), the oil tank platform (22) and the crankcase positioning rod (41) together. The weight of the entire petrol engine is supported through the base, so that the supporting stability is high, deformation or wear of an oil tank can be prevented effectively, the service life of the oil tank is prolonged effectively, and the safety of the oil tank is enhanced effectively.

Description

technical field [0001] The invention belongs to the technical field of gasoline engines, and in particular relates to 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 by the oi...
