[0032] like Figures 1 to 7 As shown in the figure, this embodiment provides a fuel tank for a generator set. The fuel tank for a generator set includes a fuel tank body 1, a level gauge 11 located on the surface of the fuel tank body 1, an oil return port 12 located on the top of the fuel tank body 1, a cover plate 13, and a filling pipe 14. The surface of the filling pipe 14 is provided with a sealing element 2.

[0033] The sealing element 2 includes a sealing cap 21 fitted onto the surface of the refueling pipe 14. The inner side of the sealing cap 21 has an internal threaded groove 22. A telescopic rod 23 and a first spring 24 are fixedly connected inside the sealing cap 21. The first spring 24 is arranged in a circular array. The telescopic rod 23 is located inside the first spring 24. A sealing ring 25 is fixedly connected to the bottom of the telescopic rod 23 and the first spring 24. The two ends of the first spring 24 and the telescopic rod 23 are fixedly connected to the inner side of the sealing cap 21 and the sealing ring 25, respectively. The sealing ring 25 is located inside the sealing cap 21 and is movably connected to it. The first spring 24 can enhance the sealing effect of the sealing ring 25, thereby improving the tightness and stability of the connection and reducing the possibility of oil leakage.

[0034] An inner ring 26 is fixedly connected to the inner side of the refueling pipe 14, and an external thread 27 is installed on the outer side of the refueling pipe 14.

[0035] The sealing cap 21 and the refueling pipe 14 are connected by an internal thread groove 22 and an external thread 27. The threaded fixing structure helps to increase the sealing effect of the connection point and improve the sealing performance of the refueling pipe 14.

[0036] The sealing ring 25 is located on the surface of the inner ring 26 and is movably connected to it. The overall diameter of the inner ring 26 is the same as the diameter of the sealing ring 25, so that the sealing ring 25 can be firmly attached to the inner ring 26, thereby achieving a good sealing effect.

[0037] The outer surface of the sealing cover 21 is fixedly connected with anti-slip strips 28. The anti-slip strips 28 are arranged in a circular array. The anti-slip strips 28 can help the staff to complete the sealing operation better.

[0038] A ladder 3 is installed on the other side of the fuel tank body 1. A connecting rod 31 is movably connected to one side of the fuel tank body 1. There are two sets of connecting rods 31, located on both sides of the ladder 3. The connecting rods 31 are movably connected to the ladder 3 to ensure the stability of the ladder 3. (See also...) Figure 5 In the deployed state, connecting rod 31 is perpendicular to the fuel tank body 1, and the ladder 3, connecting rod 31, and fuel tank body 1 form a stable triangular structure. Additionally, Figure 4 The ladder 3 is in the retracted state, which reduces the floor space occupied. The inner sides of both ends of the ladder 3 are sloped, which makes it more stable.

[0039] The surface of the ladder 3 has a groove 32. A chain 33 is installed on one side of the oil tank body 1, inside the connecting rod 31. The chain 33 and the groove 32 are on the same horizontal plane. A triangular block 34 is fixedly connected to the outer side of the top of the ladder 3. A positioning piece 35 is installed on one side of the oil tank body 1, at the top of the connecting rod 31. (Refer to...) Figure 5The triangular block 34 can position the ladder 3 when it is unfolded. When the ladder 3 is unfolded, the triangular block 34 is located at the bottom of the positioning member 35, as shown in the reference. Figure 4 The chain 33 and the groove 32 are on the same horizontal plane, which makes it easy to position the ladder 3 when it is retracted. When the ladder 3 is retracted, the triangular block 34 is located on top of the positioning part 35.

[0040] A fixing rod 331 is fixedly connected to one side of the fuel tank body 1. The fixing rod 331 is movably connected to the chain 33. A bolt 332 is movably connected to the other end of the chain 33.

[0041] A nut 333 is fixedly connected to one side of the fuel tank body 1, at the bottom of the fixing rod 331. One end of a bolt 332 is located inside the nut 333 and is movably connected to it. When connecting the two, simply tighten the bolt 332 slightly to make it threadedly connected to the nut 333, avoiding the chain 33 from winding. Figure 4 As shown, this state allows the stowed ladder 3 to be positioned, as follows. Figure 6 As shown, this state allows the ladder 3 to be easily retracted and placed inside the groove 32, preventing the chain 33 from hanging straight down and making it inconvenient to pass through the groove 32.

[0042] The positioning component 35 includes a housing 351 fixed to one side of the oil tank body 1. The housing 351 is located on both sides of the ladder 3. A sliding groove 352 is provided inside the housing 351. A second spring 353 is fixedly connected inside the housing 351. A positioning block 354 is movably connected inside the housing 351. The other end of the second spring 353 is fixedly connected to the positioning block 354, which allows the positioning block 354 to be telescopic, so as to position the triangular block 34.

[0043] Both sides of the positioning block 354 are fixedly connected to limit rods 355. The limit rods 355 are located inside the slide groove 352 and are movably connected to it. The limit rods 355 extend to the outside of the housing 351 through the slide groove 352. The outer surface of the limit rods 355 is provided with a concave surface 356. The setting of the limit rods 355 can prevent the positioning block 354 from being disconnected from the housing 351, and at the same time can make it move more stably inside the housing 351.

[0044] Limiting blocks 357 are fixedly connected to both sides of the housing 351. Two sets of limiting blocks 357 are provided, located at the top and bottom of the slide groove 352 respectively. A bolt 358 is movably fitted inside the limiting block 357. Figure 4 In the middle, the plug 358 fits against the concave surface 356, so that the positioning block 354 is completely inside the housing 351, so that the positioning of the triangular block 34 can be canceled.

[0045] In use, the sealing cap 21 is fitted onto the surface of the refueling pipe 14, and the sealing cap 21 is rotated so that it is threadedly connected to the external thread 27 through the internal thread groove 22. During this process, the sealing ring 25 is located on the surface of the inner ring 26. Through the continuous rotation of the sealing cap 21, the sealing ring 25 will transmit pressure to the surface of the first spring 24 and the telescopic rod 23. The first spring 24 is compressed and deformed, which can make the connection between the sealing ring 25 and the inner ring 26 more stable. In this way, the sealing effect of the sealing ring 25 can be strengthened, thereby improving the tightness and stability of the connection and reducing the possibility of oil leakage. At the same time, the use of threaded fixing helps to increase the sealing effect of the connection point and improve the sealing performance of the refueling pipe 14.

[0046] Additionally, during maintenance of the return port 12, cover plate 13, and filler pipe 14, the bolt 332 can be rotated in the opposite direction to disconnect it from the nut 333, thus canceling the positioning of the ladder 3. Then, the ladder 3 can be pulled directly to form a connection via the connecting rod 31. Figure 5 In this process, the connecting rod 31 flips from a state parallel to the fuel tank body 1 to a vertical state. At the same time, the ladder 3 flips so that it flips around the connection point with the connecting rod 31 until its top is in contact with one end of the housing 351, that is, the bottom of the positioning block 354 is in contact with the connection point of the housing 351. The bottom of the ladder 3 is in contact with the ground, and the triangular block 34 is located at the bottom of the housing 351. The unfolding operation can be completed, which makes it convenient for the staff to carry out maintenance and repair work on the fuel tank body 1.

[0047] Compared to a generator set fuel tank patent with publication number CN216691294U, the ladder 3 mentioned therein is set vertically, and the ladder 3 needs to be installed and disassembled when in use or not in use; this method can save floor space and is simpler to operate. In addition, by tilting the ladder 3 during use, it is more in line with ergonomic principles and is easier to climb, making the operation more comfortable for the staff.

[0048] When restoring the ladder 3, the limiting rod 355 can be pulled to move it along the inside of the slide 352 until it is located at the other end of the slide 352. Then, the plug 358 is inserted into the inside of the limiting block 357 so that one side of it is located on the surface of the concave surface 356. At this time, the positioning block 354 is completely located inside the housing 351. At this time, the positioning of the triangular block 34 can be canceled, which makes the restoration of the ladder 3 convenient.

[0049] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
