Abstract
Description
Technical Field
[0001] The utility model relates to the field of tractor accessories, and specifically to an external fuel tank dipstick for a tractor that prevents rainwater from flowing back. Background Art
[0002] In an automobile, a dipstick is a commonly used control dipstick for checking the inventory of lubricating oil in the hole. Since there is a turning path in the dipstick insertion hole, it is required that the deformation of the dipstick during insertion can rebound and recover when it is pulled out. For equipment such as tractors that need to work in special environments for a long time, the fuel tank often needs to be exposed outside the equipment to facilitate replenishment of the fuel tank and viewing of the liquid level height. However, after working for a long time, the temperature inside the fuel tank rises, resulting in an increase in air pressure. Therefore, the dipstick of the tractor fuel tank needs to have a vent hole to achieve air pressure balance inside and outside the fuel tank, thereby preventing problems caused by abnormal air pressure. However, the existing vent holes, like the fuel tank of the dipstick, are all exposed outside the equipment. In the case of rainy weather or other situations with splashing water, water easily enters the fuel tank through the vent hole and contaminates the oil. Summary of the Utility Model
[0003] The purpose of the utility model is to overcome the deficiencies of the above traditional technologies, and provide an external fuel tank dipstick for a tractor that can prevent rainwater from flowing back, which can ensure air pressure balance inside the fuel tank without affecting the exhaust of the fuel tank, and can also prevent external rainwater from entering the fuel tank through the exhaust hole.
[0004] The purpose of the utility model is achieved by the following technical measures:
[0005] An external fuel tank dipstick for a tractor that prevents rainwater from flowing back, characterized in that: it includes a fixed mounting plate, the upper surface of the fixed mounting plate is fixedly connected with a disassembly and assembly bolt, an exhaust component for discharging excess air in the fuel tank is arranged inside the disassembly and assembly bolt, the lower surface of the fixed mounting plate is fixedly connected with a sealing mounting column, and the lower surface of the sealing mounting column is fixedly connected with a measuring dipstick for measuring the liquid level height of the oil in the fuel tank.
[0006] As an improvement: the exhaust component includes an exhaust groove, the exhaust groove is opened on the side surface of the disassembly and assembly bolt, and a drainage slope is opened on the lower surface of the exhaust groove.
[0007] As an improvement: an exhaust hole is opened in the exhaust groove, the exhaust hole sequentially penetrates through the disassembly and assembly bolt, the fixed mounting plate and the sealing mounting column, and one end of the exhaust hole is located at a high point on one side of the drainage slope.
[0008] As an improvement: the side surface of the sealing mounting column is fixedly connected with a connection thread for mating connection with the fuel tank.
[0009] As an improvement: a sealing rubber ring is fixedly connected to the lower surface of the fixed mounting plate, and the sealing rubber ring is a rubber sealing rubber ring.
[0010] Due to the adoption of the above technical solution, compared with the prior art, the advantages of the present utility model are:
[0011] The gas generated in the fuel tank can be effectively discharged through the provided exhaust holes, and the air pressure difference inside and outside the fuel tank can be balanced. The provided exhaust grooves are recessed inward, which can effectively prevent rainwater from easily flowing into the fuel tank through the exhaust holes. The provided drainage slopes can allow the water droplets splashed into the exhaust grooves to flow down, preventing the water droplets from entering the exhaust holes. The provided connecting threads can be better matched and connected with the fuel tank. The provided disassembly and assembly bolts facilitate the rotation operation of the connecting threads. The provided sealing rubber ring can play a sealing role, and the liquid level height in the fuel tank can be judged by the height of the oil adhering to the measuring dipstick.

[0017] Embodiment: As shown in the attached Figures 1 to 4 figure, an external fuel tank dipstick for a tractor that prevents rainwater from flowing back includes a fixed mounting plate 1. A disassembly and assembly bolt 2 is fixedly connected to the upper surface of the fixed mounting plate 1. An exhaust component 3 for discharging the excess air in the fuel tank is arranged inside the disassembly and assembly bolt 2. A sealing mounting column 5 is fixedly connected to the lower surface of the fixed mounting plate 1. A measuring dipstick 4 for measuring the liquid level height of the oil in the fuel tank is fixedly connected to the lower surface of the sealing mounting column 5. The liquid level height in the fuel tank can be judged by the height of the oil adhering to the measuring dipstick 4.
[0018] The exhaust assembly 3 includes an exhaust groove 31 which is formed on the side surface of the dismounting and mounting bolt 2, and a drainage slope 33 is formed on the lower surface of the exhaust groove 31. By arranging the exhaust groove 31 to be recessed inward, it can effectively prevent rainwater from easily flowing in through the exhaust hole 32.
[0019] An exhaust hole 32 is formed in the exhaust groove 31, and the exhaust hole 32 sequentially penetrates through the dismounting and mounting bolt 2, the fixed mounting plate 1 and the sealing mounting column 5. One end of the exhaust hole 32 is located at the high point on one side of the drainage slope 33. By arranging the exhaust hole 32, the gas generated in the fuel tank can be effectively discharged, and the air pressure difference inside and outside the fuel tank can be balanced. By arranging the drainage slope 33, the water droplets splashed into the exhaust groove 31 can flow down, preventing the water droplets from entering the exhaust hole 32.
[0020] A connection thread 7 for cooperating with the fuel tank is fixedly connected to the side surface of the sealing mounting column 5. By arranging the dismounting and mounting bolt 2, it is convenient to rotate the connection thread 7. The connection thread 7 can also serve the purpose of sealing the fuel tank and prevent the sealing mounting column 5 from falling off due to high-frequency vibration during the operation of the tractor.
[0021] A sealing rubber ring 6 is fixedly connected to the lower surface of the fixed mounting plate 1, and the sealing rubber ring 6 is a rubber sealing rubber ring. By arranging the sealing rubber ring 6, a sealing effect can be achieved. The sealing rubber ring 6 is in a ring structure and can better fit the shape of the fixed mounting plate 1, thereby achieving a better sealing effect.
