Description

Technical Field

[0001] This utility model relates to the field of gasoline generator technology, and in particular to a fuel tank cover for a gasoline generator. Background Technology

[0002] Among the many components of a gasoline generator, the fuel tank cap is crucial. Its main purpose is to seal the fuel tank, prevent fuel leakage, and ensure the generator can operate continuously and stably.

[0003] Currently, most gasoline generator fuel tank caps are directly exposed, lacking effective covering and protection. This design makes the fuel tank cap susceptible to various environmental factors. Regarding waterproofing, rainwater may seep into the fuel tank through the gap between the cap and the tank during rainy weather. When fuel is diluted by rainwater, its combustion performance is severely affected, leading to reduced generator output power, unstable operation, and potentially damage to engine components. In terms of dust prevention, exposed fuel tank caps easily attract dust and debris from the air. This dust and debris not only affects the appearance of the fuel tank cap but may also enter the fuel tank when refueling, contaminating the fuel. Once contaminated fuel enters the engine, it accelerates engine wear, reducing engine lifespan and performance.

[0004] In summary, the fuel tank cap of existing gasoline generators is directly exposed to the external environment and does not have waterproof or dustproof functions. Utility Model Content

[0005] The purpose of this utility model is to provide a fuel tank cover for a gasoline generator, which solves the problem that the fuel tank cover of existing gasoline generators is directly exposed to the external environment and does not have waterproof and dustproof functions.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0020] Please see Figures 1 to 4 This utility model provides a fuel tank cover for a gasoline generator. The fuel tank cover includes a fuel tank cover body 101, a shield, and a fixing protrusion 102. The fuel tank cover body 101 is installed at the fuel tank opening 103 (the fuel tank opening 103 of the gasoline generator, the overall structure of the gasoline generator is not shown in the figure). An integrally formed mounting base 104 is provided on the outside of the fuel tank opening 103. A protective protrusion 105 is also integrally formed on the periphery of the fuel tank opening 103. The protective protrusion 105 surrounds and is provided at the fuel tank opening 103. On the outside of the fuel tank cap body 101, the protective protrusion 105 has a recess 106 at one end away from the mounting base 104, and the fixing protrusion 102 is provided at the recess 106.

The connecting block 109 is fixedly provided at one end of the cover body 108 near the mounting base 104. The end of the connecting block 109 away from the cover body 108 is hinged between the two connecting ears 110.

[0023] In this embodiment, since the connecting block 109 is fixedly connected to the cover 108, the cover is manufactured using an integral molding technology, making the overall structure of the cover more robust.

[0024] Furthermore, a plurality of reinforcing ribs 111 are provided on the upper surface of the connection between the connecting block 109 and the cover 108, and the plurality of reinforcing ribs 111 are evenly arranged in the middle of the connecting block 109.

[0025] In this embodiment, the connection structure between the connecting block 109 and the cover 108 is made more robust by the arrangement of multiple reinforcing ribs 111.

[0026] Furthermore, a sealing strip 112 is provided at the inner edge of the shield, and the sealing strip 112 is in contact with the outer wall of the protective protrusion 105.

[0027] In this embodiment, the sealing strip 112 enhances the sealing performance of the shield when it is closed, effectively improving its waterproof and dustproof effect, and further protecting the fuel tank cap and fuel in the fuel tank from the influence of the external environment.

[0028] Furthermore, the mounting base 104 is provided with side baffles 113 on both sides of the side facing the fuel tank cap body 101, and both side baffles 113 are fixedly connected to the protective protrusion 105. The top baffle 114 is provided at the top of the side of the mounting base 104 facing the fuel tank cap body 101, and the top baffle 114 is located between the tops of the two side baffles 113. The cover 108 is disposed outside the protective protrusion 105, the two side baffles 113 and the top baffle 114.

[0029] In this embodiment, the side baffle 113 and the top baffle 114 are used to protect the connection between the shield and the mounting base 104, preventing dust or rainwater from entering the interior of the protective protrusion 105 through the connection between the shield and the mounting base 104, thereby further improving the protective effect of the shield on the fuel tank opening 103.

[0030] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
