Embodiment approach 1

[0029] Implementation mode one, refer to figure 1 , figure 2 , image 3 , Figure 5 , a fuel tank cap with metering function, including a cap body (1), a scale mark (11) is provided on the upper end of the cap body (1), and a transparent window (12) is provided on the side of the scale mark (11), and the transparent window ( 12) A scale slider (not shown in the figure) is placed in the scale groove (13) set below; a screen cylinder (not shown) is placed under the cover (1) corresponding to the scale slider (not shown in the figure). 2) The indicator rod (3) inside, the screen cylinder (2) is connected with the cover body (1); the indicator rod (3) is also covered with a floating body (4).

[0030] The material of the screen cylinder (2) is plastic or formed by wrapping metal sheets.

[0031] When in use, fill the fuel tank with oil, and then insert the fuel tank cap from the fuel tank port, because the screen cylinder (2) is located under the fuel tank cap body (1), and t...

Embodiment approach 2

[0033] Embodiment 2, based on Embodiment 1, the upper end of the cover (1) is also provided with a sealed transparent cover (not shown in the figure). A good second protection effect can be achieved by sealing the transparent cover (not shown in the figure), and the sealed transparent cover (not shown in the figure) can also be made in the form of a convex lens, which can protect the upper end of the cover (1) The scale mark (11) and the content in the transparent window (12) are enlarged to make the oil quantity display more intuitive.

Embodiment approach 3

[0034] Embodiment 3, based on Embodiment 1, the scale slider (not shown in the figure) is connected to the end of the indicator rod (3).

Abstract

A fuel tank cap with a metering function aims to solve the problems that the fuel quantity in a fuel tank can be known only through a sensor with a complex structure and the cost is high. The fuel tank cap comprises a cap body, and is characterized in that graduation marks are arranged at the upper end of the cap body; a transparent window is arranged on one side edges of the graduation marks; a scale sliding block is arranged in the scale trough arranged under the transparent window; an indication rod arranged in a screen stencil cylinder is arranged under the cap body in a position corresponding to the scale sliding block; the screen stencil cylinder is connected with the cap body; and a floating body is sleeved on the indication rod. The fuel tank cap is smart in structure, is designed reasonably, can measure fuel quantity accurately, occupies a small space, and is high in compatibility, low in manufacturing cost and strong in practicability. Therefore, requirements on fuel tank caps of various sizes can be met.

Description

technical field [0001] The invention relates to a fuel tank cap, in particular to a fuel tank cap with metering function, which belongs to the technical fields of international patent main classifications B60 and B62. Background technique [0002] Fuel tank cap refers to the sealing cover on the box for storing gasoline and diesel oil. The shape is square or round, made of stainless steel, and has good airtightness. The existing oil tank cap has simple structure and single function. [0003] When the oil tank is used as an oil supply device for mechanical equipment, if you want to know how much oil is in the oil tank, you can only know it through the oil quantity sensor installed in the oil supply port. Like a car, it can only be read from the dashboard when the car is started, and it is inconvenient to read the data. In addition, other equipment must be installed in the fuel tank, which increases the complexity of the entire fuel tank system. For some sensors such as gen...
