Description

Technical Field

[0001] The utility model relates to the technical field of generators, in particular to a structure for facilitating the disassembly and assembly of a generator oil tank inspection cover. Background Art

[0002] The core component of an outdoor generator is the engine, typically a gasoline or diesel engine. Regular checks of engine oil and fuel levels are required to ensure proper operation. Consequently, the generator's fuel tank access panel must be frequently opened. To ensure the generator's strength, the access panel is typically constructed of steel. Specific dimensions are also required, and they cannot be too small. This results in a relatively heavy weight, typically between 5kg and 15kg. Consequently, maintenance personnel require two people to remove or install the access panel, making it difficult for one person to simultaneously support and install the panel. This results in inconvenient installation and low maintenance efficiency. Utility Model Content

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model for which protection is sought, but merely represents the selected embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Example

[0038] Combine Figures 1 to 8 , this embodiment provides a structure for facilitating the disassembly and assembly of the generator oil tank inspection port cover. Specifically, an oil tank inspection port is provided near the bottom of the generator body 1, and the inspection port cover is installed on the oil tank inspection port. The inspection port cover includes a bottom plate 2, a cover plate 3 and a sealing member 4. The bottom plate 2 is fixedly connected to the generator body 1, and the cover plate 3 is connected to the bottom plate 2 by screws 5. The sealing member 4 is arranged between the bottom plate 2 and the cover plate 3. A bearing portion 11 is provided along the outer wall of the generator. The bearing portion 11 has a bearing surface 111 provided in the horizontal direction. The cover plate 3 is configured to be positioned in the vertical direction by being placed on the bearing surface 111 during disassembly and assembly.

[0039] For example, when installing the cover plate 3, the operator first places the cover plate 3 on the bearing portion 11 so that the cover plate 3 is positioned vertically by the bearing surface 111, and then moves the cover plate 3 horizontally along the bearing surface 111 so that the mounting hole 31 on the cover plate 3 is aligned with the screw hole 21 on the base plate 2, and then the cover plate 3 and the base plate 2 can be directly locked with the screws 5.

[0040] It should be noted that in this embodiment, the support portion 11 is provided so that the cover plate 3 can be directly placed on the support portion 11 during assembly and disassembly, thereby positioning it vertically. This reduces the number of positioning steps and frees the operator's hands from supporting the cover plate 3. Without the need to support the cover plate 3 with their hands, the cover plate 3 can be assembled and disassembled by one person, resulting in highly efficient assembly and disassembly. Furthermore, the cover plate 3 does not need to be held for extended periods, saving time and effort and providing a convenient and quick solution.

[0041] In a preferred embodiment, a limiting surface 112 perpendicular to the bearing surface 111 is provided on the bearing portion 11, and a channel for inserting the cover plate 3 is formed between the limiting surface 112 and the outer wall of the generator body 1. For example, the cross-sectional shape of the bearing portion 11 is L-shaped. The cover plate 3 can be inserted vertically from the opening of the bearing portion 11, or inserted from the side of the bearing portion 11. There is no restriction on the insertion method, which is convenient for the operator to flexibly adjust it in combination with the maintenance site. At the same time, the setting of the limiting surface 112 can further restrict the cover plate 3, avoid the cover plate 3 from falling when it is mounted on the bearing portion 11, and ensure the stability of the cover plate 3 when mounted on the bearing portion 11. Among them, the bearing portion 11 can be integrally formed with the generator body 1, or it can be fixed to the generator body 1 by assembly, welding, gluing, etc., without specific limitation.

[0042] Preferably, two bearing portions 11 are provided below each fuel tank access opening to support both ends of the cover plate 3 to ensure balanced force on both ends of the cover plate 3. In other embodiments, multiple bearing portions 11 may be arranged along the periphery of the fuel tank access opening to ensure stability of the cover plate 3 when mounted.

[0043] In an alternative embodiment of the present invention, based on the above-mentioned embodiment, a protective portion 12 is provided as a raised portion on the outer wall of the generator body 1. Preferably, the protective portion 12 extends vertically along both sides of the access opening and is positioned higher than the cover plate 3. This prevents collisions during outdoor movement or use of the generator, which could cause the cover plate 3 to misalign or the screws 5 to break. Furthermore, the triangular cross-section of the protective portion 12 reduces the material required to form the protective portion 12 and prevents scratches between the protective portion 12 and external components.

[0044] In another embodiment, a sealing groove 22 is provided on the base plate 2, and a sealing member 4 is installed in the sealing groove 22. The sealing member 4 is in a racetrack shape, and a sealing portion 41 is provided on a side facing the cover plate 3. For example, the sealing member 4 is made of silicone or rubber, and the cross-section of the sealing portion 41 is semicircular. The provision of the sealing portion 41 can enhance the sealing between the sealing member 4 and the cover plate 3, thereby preventing oil leakage from the fuel tank.

[0045] In other embodiments, the base plate 2 is secured to the generator body 1 by welding, and the screws 5 on the cover plate 3 are evenly distributed along its periphery to ensure balanced force on the cover plate 3. Furthermore, the cover plate 3 is provided with countersunk holes, and the screws 5 are countersunk screws or hexagon socket screws. The screws 5 are fitted with spring washers 6 and flat washers. When the screws 5 are tightened, the screw heads press against the spring washers 6, preventing the screws 5 from loosening and ensuring a reliable connection between the cover plate 3 and the base plate 2.

[0046] The above are only preferred implementations of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention fall within the protection scope of the present invention.
