Description

Technical Field

[0001] The utility model relates to the technical field of oil tanks, in particular to an oil tank with excellent sealing performance. Background Art

[0002] An oil tank is a container specially used to store liquid fuel or other liquid chemicals, and is widely used in the petroleum, chemical, transportation and other industries. According to the different uses, materials and installation methods, oil tanks can be divided into many types. Publication No. CN220164726U discloses an oil tank device, which includes a tank body, an oil inlet valve, an oil outlet valve and an oil inlet pipe. The oil inlet pipe is arranged in the tank body. The oil inlet pipe includes a first end and a second end arranged oppositely. The oil enters the first end through the oil inlet valve and enters the tank body through the second end. When using the oil, the oil outlet valve is opened to take the oil so that the oil flows into the transformer. The oil flowing into the transformer then passes through the oil inlet valve and the oil inlet pipe in turn and enters the tank body to complete the oil circulation. Since the oil inlet pipe includes a first end and a second end that are relatively arranged, the first end is arranged close to the lower wall of the tank body, the second end is arranged close to the upper wall of the tank body, and the oil inlet valve is connected to the first end, and the oil outlet valve is arranged between the oil inlet valve and the lower wall of the tank body, the oil enters the first end from the oil inlet valve and enters the tank body from the second end. This oil filling method allows the oil to flow from the upper part of the tank body to the lower part, effectively preventing debris from settling at the tail of the oil tank device, and facilitating the cleaning of the tank body. However, the traditional oil tank has deficiencies in terms of sealing and ease of operation. The connection between the feed port and the lid often cannot achieve an ideal sealing effect, which easily leads to liquid leakage. During operation, the lack of a stable sealing structure and guide design makes the opening and closing operation of the oil tank more cumbersome, increases the difficulty of use and the risk of operation, and has poor practicality, which needs to be improved.

[0022] Embodiment 2

[0023] See also Figure 1 , 2 A protective frame 19 is fixedly installed on the surface of the shell 2 to protect the surface of the shell 2. A reinforcing rib 20 is fixedly installed on the side of the protective frame 19 to reinforce the protective frame 19. A protective pad 21 is fixedly installed on the surface of the protective frame 19 to play a buffering role. The protective frame 19 is fixedly connected to the base 1 so that the protective frame 19 is clamped and fixed on the base 1. The reinforcing rib 20 is fixedly connected to the shell 2 so that the protective frame 19 is fixed on the shell 2 more stably and firmly.

[0024] Working principle: First, when filling oil is needed, first grasp the turntable 12 so that the turntable 12 drives the threaded rod 11 to rotate from the inside of the fixed block 9, and then grasp the handle 13 and pull it, so that the handle 13 drives the cover 4 to rotate on the surface of the feed port 3, and then infuse. When the infusion is completed, grasp the handle 13 to close the cover 4, and grasp the position of the turntable 12 to rotate it, so that the turntable 12 drives the threaded rod 11 to rotate from the inside of the block 10 to the inside of the fixed block 9, and then grasp the rotating head 15 to rotate it, so that the rotating head 15 drives the screw rod 14 to rotate. When the screw rod 14 rotates, it can drive the sealing plate 16 to slide from the position of the feed port 3 to the position of the gear ring 8, so that the gear ring 8 and the sealing plate 16 are pressed tightly to play a sealing role. The sealing effect is achieved. When the sealing plate 16 moves, it will drive the guide rod 17 to slide inside the cover 4, so that the moving position of the sealing plate 16 can be observed through the scale groove on the guide rod 17. At the same time, the sealing ring 7 and the sealing plate 16 can achieve a double sealing effect. The worker can also observe the internal situation through the position of the observation window 5. When the oil needs to be discharged and transported, the oil can be transported out through the position of the discharge valve 6. The surface of the outer shell 2 can be protected by the protective frame 19 to reduce the risk of the outer shell 2 being hit. The position of the reinforcing rib 20 can make the protective frame 19 more stably fixed and the mounting frame more firmly fixed. The protective pad 21 can buffer the collision to avoid large vibration and shaking caused by the collision.
