[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0023] Please refer to Figures 1-6 The utility model provides a kind of technical scheme: a kind of oil tank liquid level measuring instrument, including pedestal 1, limiting mechanism 2, knob 201, rubber antiskid block 202, scale rod 3, bottom plate 4, float 5, sleeve 6, square bar 7, positioning sleeve 8 and collar 9, the end inner wall of pedestal 1 is installed with limiting mechanism 2, the end fixedly connected with scale rod 3 of pedestal 1 lower surface, and the lower end outer wall of scale rod 3 is equipped with bottom plate 4, the outer wall of scale rod 3 is movably connected with float 5, and the end fixedly installed with sleeve 6 of float 5 upper surface, and the inner wall of sleeve 6 is movably connected with square bar 7, and the lower end outer wall of square bar 7 is fixedly provided with positioning sleeve 8, while the outer wall of positioning sleeve 8 is equipped with collar 9.

[0024] Limiting mechanism 2 includes knob 201 and rubber antiskid block 202, and knob 201 is movably installed on the end inner wall of pedestal 1, and the end surface of knob 201 is fixedly connected with rubber antiskid block 202, to limit square bar 7 by limiting mechanism 2, to ensure the stability of float 5, and then facilitate user to take out the device from oil tank, and determine the oil tank liquid level height by the position of float 5.

[0025] Knob 201 is threadedly connected with pedestal 1, and rubber antiskid block 202 is attached to square bar 7, to facilitate user to rotate knob 201, so that knob 201 moves relative to pedestal 1, thereby driving rubber antiskid block 202 to move so that rubber antiskid block 202 tightly adheres to square bar 7, and then the limiting of square bar 7 is completed, at this time, float 5 and scale rod 3 are in relatively stable state.

[0026] Scale rod 3 and bottom plate 4 are threadedly arranged, to facilitate user to rotate bottom plate 4 to disassemble and assemble bottom plate 4, thereby facilitating user to move and disassemble float 5.

[0027] Float 5 and scale rod 3 form a sliding structure, and square bar 7 is slidably connected with pedestal 1, to facilitate the device to be inserted into oil tank for use, float 5 always floats on oil product along with scale rod 3, and float 5 drives square bar 7 to slide relative to pedestal 1 along with the movement of float 5.

[0028] The sleeve 6 and the square rod 7 are slidably connected, and the sleeve 6 and the positioning sleeve 8 are fitted together. The collar 9 is threadedly connected to the sleeve 6 and the positioning sleeve 8 respectively, and the collar 9 and the float 5 are fitted together. This allows the user to rotate the collar 9 to disengage it from the sleeve 6, thereby facilitating the user to move and disassemble the square rod 7, and thus facilitating the replacement of the damaged float 5.

[0029] Working principle: When using this oil tank level measuring instrument, firstly as follows... Figures 1-6 As shown, the user inserts the device into the oil tank. Then, the user moves the device so that the base plate 4 is flush with the bottom of the oil tank. At this point, the scale rod 3 is perpendicular to the bottom of the oil tank, ensuring measurement accuracy. Simultaneously, the float 5 floats on the surface of the oil using buoyancy. Next, the user rotates the knob 201, which moves relative to the base 1. Then, the knob 201 moves the rubber anti-slip block 202 so that it is pressed tightly against the square rod 7, thus limiting the square rod 7 and ensuring that the float 5 and the scale rod 3 are in a relatively stable state. Next, the user removes the device from the oil tank and observes the position of the scale rod 3 indicated by the lower surface of the float 5 to obtain the oil level in the tank. Then, the user rotates the knob 201 to disengage the rubber anti-slip block 202 from the square rod 7. Finally, the user inserts the device into a new oil tank as described above. This device is used to measure the liquid level of different oil tanks, thus facilitating the measurement of liquid levels in various oil tanks and improving its practicality. When the float 5 on the device is accidentally damaged, the user rotates and removes the base plate 4, then moves the float 5 to disengage it from the scale rod 3. Next, the user rotates the collar 9 to move it along the positioning sleeve 8 and disengage it from the retaining sleeve 6. Then, the user moves and removes the square rod 7 to complete the removal of the damaged float 5. The user then inserts the square rod 7 into the retaining sleeve 6 on the new float 5. Next, the user rotates the collar 9 in the opposite direction to fit the collar 9 onto the new retaining sleeve 6. Finally, the user tightens the collar 9 to fit the collar 9 against the new float 5, thus completing the replacement of the float 5. Therefore, the device facilitates the replacement of damaged float 5, thereby preventing damage to the float 5 from affecting the use of the device.
