[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example

[0029] See also Figure 1-Figure 4 , the utility model provides the following technical solutions:

[0030] The sealing structure between the sensor and the oil tank includes:

[0031] Sealing cover 1;

[0032] A sealing rubber ring 2, the sealing rubber ring 2 is fixedly connected to the circumferential surface of the sealing cover 1;

[0033] A matching slider 3, wherein two matching sliders 3 are provided, and both matching sliders 3 are fixedly connected to the lower end of the sealing cover 1;

[0034] A rebound slider 4, wherein two rebound sliders 4 are provided, and the two rebound sliders 4 are respectively slidably connected in the two matching sliders 3;

[0035] The pull handle 5 is provided with two pull handles 5 , and the two pull handles 5 are respectively fixedly connected to the upper ends of the two rebound sliders 4 .

[0036] In a specific embodiment of the utility model, the sealing structure of the oil level sensor 12 and the fuel tank ensures that the fuel tank is airtight and easy to operate and detect through a series of sophisticated mechanical designs, which are as follows: a sealing cover 1 covers the opening of the fuel tank, and a sealing rubber ring 2 is carried on its circumference to form the first leak-proof barrier; two matching sliders 3 are configured below, which are firmly fixed to the lower end of the sealing cover 1, laying the foundation for the sliding trajectory of the rebound slider 4. The two rebound sliders 4 are nested in the slider and can slide smoothly in a specific direction; a handle 5 is fixed on the top of each rebound slider 4 as a user interaction interface, so that the operator can drive the slider below by pulling the handle 5, thereby realizing easy opening and closing of the sealing cover 1. This linkage mechanism not only ensures the sealing of the fuel tank, but also can be easily opened during daily inspection or refueling, reducing the risk of leakage and improving safety and convenience of use.

[0037] For details, please refer to Figure 1-Figure 4 The front ends of the two rebound sliders 4 are respectively fixedly connected with two lockers 6, the two matching sliders 3 are respectively slidably connected with two lockers 6, and the upper ends of the sealing covers 1 are fixedly connected with a plurality of matching rotators 7.

[0038] In this embodiment: In this design, the locking devices 6 installed at the front ends of the two rebound sliders 4 interact with the corresponding locking devices 6 sliding inside the two matching sliders 3 to form a safety locking mechanism. When the rebound sliders 4 are pushed to the final position after the operation is completed, the locking devices 6 will engage with each other to fix the positions of the rebound sliders 4 and the sealing cover 1, ensuring the stability and durability of the sealing state of the oil tank. In addition, the multiple matching rotators 7 equipped on the upper end of the sealing cover 1 can further enhance the tightness of the system and the flexibility of operation through interaction with other components.

[0039] For details, please refer to Figure 1-Figure 4 Two rotating shafts 8 are rotatably connected in the multiple matching rotators 7, and the front ends of the two rotating shafts 8 are fixedly connected to two magnetic cover plates 9. Two magnetic cover plates 9 are provided on the upper side of the sealing cover 1.

[0040] In this embodiment: multiple shaft devices 8 built into the matching rotator 7 are connected to each other through rotational motion, forming a flexible transmission system. Two magnetic cover plates 9 are fastened to the front end of the shaft device 8, and these magnetic cover plates 9 are cleverly designed and arranged on both sides of the upper part of the sealing cover 1. When the shaft device 8 rotates with the matching rotator 7, the magnetic cover plate 9 also moves accordingly, and the opening and closing or closing control of the target area is achieved by using the principle of magnetic adsorption, which not only ensures the sealing effect of the fuel tank port, but also facilitates non-destructive inspection or quick access to the interior, improves the convenience of use and the efficiency of fuel tank management, and also maintains the integrity and safety of the fuel tank structure.

[0041] For details, please refer to Figure 1-Figure 4 Two sliding grooves 10 are provided in the sealing cover 1, and two pull handles 5 are slidably connected in the two sliding grooves 10 respectively. The lower end of the sealing cover 1 is fixedly connected with two supporting rods 11 respectively.

[0042] In this embodiment: the internal structure of the sealing cover 1 is integrated with an innovative design, and two sliding grooves 10 are specially provided. The two sliding grooves 10 serve as guide rails to accurately guide the sliding movement of the two pull handles 5 to achieve the control operation of the sealing cover 1. The interaction between the pull handle 5 and the sliding groove 10 not only ensures smooth and stable operation, but also facilitates the user to intuitively perform the opening and closing operation. In addition, two support rods 11 are fixedly installed at the lower part of the sealing cover 1. This structural design strengthens the overall stability and load-bearing capacity, ensuring that the sealing cover 1 maintains a stable posture when opened.

[0043] For details, please refer to Figure 1-Figure 4 The lower ends of the two support rods 11 are fixedly connected with an oil level sensor 12, and the front end of the oil level sensor 12 is rotatably connected with a rotating measuring rod 13.

[0044] In this embodiment: In this design, the lower ends of the two support rods 11 are stably mounted with an oil level sensor 12. As a key sensing element, the oil level sensor 12 is in direct contact with the inside of the oil tank to continuously monitor the change in the liquid level. More cleverly, the front end of the oil level sensor 12 is flexibly equipped with a rotating measuring rod 13. This mechanical connection method enables the measuring rod to rotate with the fluctuation of the oil level, and converts the vertical displacement of the liquid level into a rotation angle or an electrical signal in real time, which is then accurately captured by the sensor and converted into oil level data.

[0045] For details, please refer to Figure 1-Figure 4 The circumferential surface of the rotating measuring rod 13 is rotatably connected with a measuring float 14 , and the right end of the supporting rod 11 is fixedly connected with two oil pipes 15 .

[0046] In this embodiment: a ball-type measuring float 14 is mounted on the circumferential surface of the rotating measuring rod 13. As the oil level rises and falls, the float floats freely along the measuring rod and drives it to rotate, converting the liquid level change into precise mechanical displacement. This linkage mechanism does not need to directly invade the oil, reducing wear and maintenance requirements. At the same time, two oil pipes 15 are fixedly installed at the right end of the support rod 11. They serve as transmission channels for signals or fluids, and can guide the measured oil quantity information or fuel when necessary to the external control system or related components.

[0047] The working principle and use process of the utility model: The use process is as follows: First, the operator pulls the handles 5 located on both sides of the sealing cover 1, which will drive the rebound slider 4 to slide up and down along the matching slider 3. Since the sealing rubber ring 2 is installed on the sealing cover 1, the sealing of the oil tank opening can be ensured to be unaffected during the pulling process. Once the slider reaches the predetermined position, the locking device 6 at its front end will automatically engage with the corresponding part in the slider to achieve a firm lock of the oil tank to prevent accidental opening. Furthermore, the multiple matching rotators 7 equipped on the upper end of the sealing cover 1 are embedded with a shaft 8. The operator can drive the shaft 8 by rotating these rotators, thereby rotating the magnetic cover plate 9 fixed at the front end of the shaft 8. The movable design of the magnetic cover plate 9 not only facilitates the closing and opening of the oil tank, but also ensures that a good sealing effect can be maintained even in harsh environments, because the magnetic cover plate 9 can fit tightly on the designated position on the upper side of the sealing cover 1, and the magnetic force is used to enhance the overall sealing. By using this device, the problem that the traditional oil level sensor not only fails to achieve the quick installation function, but also its installation process is quite time-consuming and labor-intensive, and even requires external tools for assistance, which undoubtedly increases the complexity of the installation. However, the present device abandons these cumbersome steps and adopts a fully manual installation method, which not only simplifies the installation process and realizes quick installation, but also does not require the assistance of external tools at all. This improvement greatly improves the flexibility of use of the overall device and brings great convenience to users.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
