AI Technical Summary
The existing fuel tank cleaning cover is prone to displacement during frequent opening and closing, resulting in poor sealing or difficulty in proper installation, which increases the workload of maintenance personnel.
A fuel tank cleaning cover was designed. By setting a positioning block and a positioning slot on the mounting base, the cleaning cover, made of easily deformable material, is rotatably connected to the mounting base to ensure that the positioning block is inserted into the slot, avoiding misalignment and shaking. Combined with a sealing ring and guide, the sealing performance and stability are improved.
This design ensures the cleaning cover is stably positioned on the fuel tank, preventing dust and impurities from entering, guaranteeing a tight seal, reducing the risk of misalignment and loosening due to vibration or external force, and simplifying the installation process.

[0024] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0025] As Figures 1-6The utility model discloses a kind of misplacement-preventing oil tank cleaning covers, including oil tank 1 (the internal article of oil tank 1 is not drawn) and cleaning cover 2, under normal circumstances, oil tank 1 cleaning cover 2 is designed to prevent dust, moisture and other pollutants from entering oil tank 1, and does not directly contact oil, however, in some specific circumstances, it can contact oil, such as: when the vehicle is refueled if it is filled too full, fuel can overflow from the fuel filler, at this time, oil tank 1 cleaning cover 2 inside can contact oil;When oil tank 1 is maintained or repaired, such as replacing fuel filter or cleaning oil tank 1, cleaning cover 2 can be removed, at this time, if there is residual fuel or accidentally spilled fuel, it is also possible to contact cleaning cover 2;In extreme cases, such as vehicle rollover accident or experience very violent vibration, fuel can be splashed to the top area of oil tank 1 due to gravity, including cleaning cover 2 position etc., the cleaning port 11 is provided on the cleaning cover 2 corresponding to the oil tank 1, the projection of the cleaning port 11 falls on the cleaning cover 2, the cleaning cover 2 is detachably connected with the oil tank 1 by bolts, buckles and the like, the mounting seat 12 is integrally formed on the oil tank 1, the cleaning port 11 is located on the mounting seat 12 and is in communication with the inside of the oil tank 1, the mounting seat 12 is circumferentially spaced apart from a plurality of positioning blocks 121, the cleaning cover 2 is made of rubber and other materials that can easily deform and is rotatably installed on the mounting seat 12, the cleaning cover 2 is provided with a positioning slot 21 corresponding to each positioning block 121, 1. Since the mounting seat 12 is rotatably connected with the cleaning cover 2, and the cleaning cover 2 is provided with a positioning slot 21 corresponding to each positioning block 121 on the mounting seat 12, when it is necessary to open the cleaning cover 2 to clean the inside of the oil tank 1, the cleaning cover 2 is moved to deform and then the positioning blocks 121 and the corresponding positioning slots 21 are separated to rotate the cleaning cover 2 to make the cleaning port 11 leak out, and after cleaning, the cleaning cover 2 is rotated towards the cleaning port 11 to make the positioning blocks 121 fall into the corresponding positioning slots 21, i.e. the cleaning cover 2 is stably positioned on the mounting seat 12 to cover the cleaning port 11, avoiding the situation that dust and impurities from the outside fall into the cleaning port 11; 2. Since the cleaning cover 2 is located above the cleaning port 11, the positioning blocks 121 are inserted into the corresponding positioning slots 21 on the cleaning cover 2 at this time, the relative position of the cleaning cover 2 and the mounting seat 12 can be determined without external force, and the cleaning cover 2 cannot rotate with the mounting seat 12, so the cleaning cover 2 will not be misaligned with the mounting seat 12 during the process of rotating the cleaning cover 2 to make it fall on the mounting seat 12 to connect with the mounting seat 12, avoiding misalignment or loosening caused by vibration or other external forces, and achieving sealing between the cleaning cover 2 and the cleaning port 11.
[0026] Preferably, each positioning plug 121 is arranged in a ladder type with the upper part narrower than the lower part, and comprises a contact surface 1211 arranged from inside to outside from top to bottom. Since each positioning plug 121 is arranged in a ladder type, when the cleaning cover 2 is moved to be sleeved on the mounting seat 12, the outermost positioning plug 121 first enters the positioning slot 21 of the mounting seat 12. At this time, the contact surface 1211 enables the positioning plug 121 to be aligned with the corresponding positioning slot 21 more smoothly. Since the bottom surface of each positioning plug 121 is wider than the upper end surface, the cleaning cover 2 is difficult to pass the bottom of each positioning plug 121 without external force, thereby further improving the stability of the cleaning cover 2 sleeved on the mounting seat 12.
[0027] The outer side of the cleaning cover 2 located in the positioning slot 21 is provided with a cover plate 22 and a matching groove 23 located outside each cover plate 22. The existence of each matching groove 23 can reduce the wall thickness of the cleaning cover 2 at the position of each positioning slot 21, so that the cleaning cover 2 can be deformed more smoothly to realize cooperation and separation with the corresponding positioning slot 21. The existence of each cover plate 22 can prevent unrelated persons from seeing and touching each positioning plug 121 in the use state of the oil tank 1, thereby increasing the safety of use.
[0028] The cleaning cover 2 comprises a rotating part 24 and a cover body 25. Each positioning slot 21 is located on the cover body 25. The front and rear sides of the rotating part 24 are protrudingly provided with rotating shafts 241. The mounting seat 12 is provided with matching plugs 122 for accommodating the corresponding rotating shafts 241 on the front and rear sides of the rotating part 24. The bottom surface of the cover body 25 abuts against the top surface of each matching plug 122. By dividing the cleaning cover 2 into two parts of the rotating part 24 and the cover body 25, and arranging the rotating shafts 241 on the two sides of the rotating part 24, the rotating part 24 can be rotatably installed on the mounting seat 12. When the cover body 25 is sleeved on the mounting seat 12, the bottom of the cover body 25 abuts against the top of the mounting seat 12, so that the rotation track of the cover body 25 is limited.
[0029] The mounting seat 12 is fixedly provided with a first sealing ring 123 at the cleaning port 11. A second sealing ring 3 is integrally formed in the cover body 25. The circumferential surface of the second sealing ring 3 abuts against the inner wall of the first sealing ring 123. The first sealing ring 123 is arranged on the mounting seat 12, and the second sealing ring 3 is arranged in the cover body 25 and tightly contacts the first sealing ring 123, thereby greatly improving the sealing performance and effectively preventing the risk of oil leakage.
[0030] Preferably, the second sealing ring 3 is arranged in a top-down tapering manner, and the second sealing ring 3 is arranged in a top-down tapering manner, so that it can better fit the first sealing ring 123 when under pressure. At this time, if the oil falls between the second sealing ring 3 and the first sealing ring 123, it will first be limited by the bottom of the first sealing ring 123 and be difficult to reach between the first sealing ring 123 and the second sealing ring 3 upward. If the oil remains on the second sealing ring 3, due to the tapering of the second sealing ring 3, the outer wall is inverted cone, and under the action of gravity, the oil can flow downward away from the second sealing ring 3 and will not accumulate on the outer periphery of the second sealing ring 3.
