The float 5 moves up and down within the internal limit rod 2 and the external limit rod 3 as the liquid level in the oil tank changes. The connecting rope 7 passes through the reserved opening at the top of the oil tank. The float 5 drives the comparison photo 20 up and down through the connecting rope 7. The liquid level inside the oil tank is indicated by the comparison photo 20 and the scale marks 27 on the outside of the external comparison plate 17 and the internal comparison plate 18.
[0020] Several groups of fixing holes 9 are provided inside the outer limiting rod 3, and the lower part of the outer limiting rod 3 is set as a connecting structure to prevent the oil from staying inside the outer limiting rod 3. A fixing screw 10 that matches the fixing hole 9 is installed on the internal thread of the lower side of the inner limiting rod 2. By moving the inner limiting rod 2 up and down along the outer limiting rod 3, the fixing screw 10 is installed in the appropriate fixing hole 9, so as to adjust the range of up and down movement of the float 5 according to the height of the oil tank box; hooks 8 are provided at both ends of the connecting rope 7, and the hooks 8 are an integral winding structure of the connecting rope 7, which does not affect the buoyancy of the float 5. The connecting rope 7 is fixedly connected to the first connecting seat 6 and the second connecting seat 21 through the hook 8, which is convenient for adjusting the height of the oil tank box. The connecting rope 7 of different lengths can be replaced; the upper mounting plate 11 is installed on the outer side of the upper part of the oil tank box, and its installation corresponds to the lower mounting plate 1. A connecting hole 12 is opened in the middle of the upper mounting plate 11 and the lower mounting plate 1. A mounting bracket 13 is fixedly welded on the upper part of the upper mounting plate 11, and a baffle 14 is fixedly welded on the upper part of the mounting bracket 13. A first roller group 15 facing the connecting hole 12 is rotatably installed inside the mounting bracket 13. The first roller group 15 ensures that the connecting rope 7 moves vertically up and down inside the oil tank box to ensure the balance of the float 5 and prevent the connecting rope 7 from being damaged by friction. Two sets of second roller groups 16 are rotatably installed on one side of the mounting bracket 13 near the outer control plate 17. In order to change the direction of the supporting connecting rope 7, the connecting rope 7 is arranged inside the first roller group 15 and the second roller group 16; four groups of mounting plates 22 are fixedly welded on the front side of the upper part of the outer control plate 17 and the lower part of the inner control plate 18, and two groups of rear outer sliding rods 26 are slidably installed on the rear inner side of the photo 20.

By sliding the front inner sliding rod 24 along the front outer sliding rod 23 and moving the rear inner sliding rod 25 along the rear outer sliding rod 26, the moving range of the alignment photo 20 corresponds to the float 5. At the same time, one side of the alignment photo 20 remains connected to the outer sliding rod to prevent the alignment photo 20 from getting stuck at the point where the inner sliding rod enters the outer sliding rod; the outer control plate 17 and the inner control plate 18 are fixedly welded with a mounting piece 19 on the rear side, which facilitates the installation of the outer control plate 17 and the inner control plate 18 on the surface of the oil tank box and can ensure that their upper and lower heights are the same as the internal height.
[0021] Working principle: When the utility model is in use, the upper mounting plate 11 is installed on the upper outer side of the oil tank, and the lower mounting plate 1 is installed on the inner upper wall of the oil tank. The two are installed and aligned. By moving the inner limiting rod 2 up and down along the outer limiting rod 3, the fixing screw 10 is installed in the appropriate fixing hole 9, so as to adjust the range of the float 5 to move up and down according to the height of the oil tank. By moving the inner control plate 18 along the inner side of the outer control plate 17, the outer control plate 17 and the inner control plate 18 are installed on the surface of the oil tank through the mounting piece 19, and can ensure that they are up and down. The height is the same as the internal height. A connecting rope 7 of appropriate length is selected. The float 5 changes with the liquid level in the tank and moves up and down within the inner limit rod 2 and the outer limit rod 3. The connecting rope 7 passes through the reserved opening at the upper part of the tank and is positioned and redirected by the first roller group 15 and the second roller group 16. The float 5 drives the comparison plate 20 to move up and down along the inner sliding rod and the outer sliding rod through the connecting rope 7. The liquid level inside the tank is indicated by the comparison plate 20 and the scale marks 27 on the outside of the outer and inner comparison plates 17 and 18.
