[0022] See also Figures 1 to 4 The present embodiment discloses a fuel filler cap capable of adjusting the oil detection height, comprising a fuel filler cap body, wherein the upper section of the fuel filler cap body is a knob section 1, and the lower section is an external thread section 2, and the fuel filler cap body is threadedly mounted with the fuel tank through the external thread section 2. The fuel filler cap body is provided with a vertically penetrating sliding channel, and an adjusting rod 3 is slidably arranged in the sliding channel of the fuel filler cap body, the bottom of the adjusting rod 3 extends out from below the bottom of the fuel filler cap body and is connected to a liquid level detection sensor 4, the top of the adjusting rod 3 extends out from above the top of the fuel filler cap body, and the adjusting rod 3 is locked at different height positions through an adjusting locking mechanism 5 arranged at the top of the fuel filler cap body.

[0023] The adjustment locking mechanism 5 includes positioning rods 6 symmetrically arranged on the left and right sides of the adjustment rod 3. Each positioning rod 6 is slidably supported by a fixed block 7 fixed on the oil cover body. The positioning rod 6 can elastically extend and retract along the left and right directions of the fixed block 7. In the natural state, the positioning rod 6 elastically extends toward the direction close to the adjustment rod 3. The left and right sides of the adjustment rod 3 are respectively provided with multiple locking grooves 8 of different heights. The left and right positioning rods 6 are respectively engaged with the locking grooves 8 on the left and right sides of the adjustment rod 3 to achieve locking of the height position of the adjustment rod 3.

[0024] The outer end of the positioning rod 6 extends out of the fixed block 7 and is provided with a mounting block 9. The outer section of the positioning rod 6 is provided with a tension spring 10. The inner and outer ends of the tension spring 10 are respectively connected to the fixed block 7 and the mounting block 9. In the natural state, under the tension of the two tension springs 10, the two positioning rods 6 elastically extend in the direction close to the adjusting rod 3.

[0025] The adjustment locking mechanism 5 also includes a pressure ring 11, which is slidably supported by two vertical guide rods 12 located on the front and rear sides of the adjustment rod 3. The two vertical guide rods 12 are fixed on the oil cover body. A limit plate 13 is provided on the top of the vertical guide rod 12 to limit the upper limit position of the pressure ring 11. The mounting blocks 9 at the outer ends of the two positioning rods 6 are respectively connected to the upper pressure ring 11 through connecting rods 22. The upper and lower ends of each connecting rod 22 are respectively hinged to the pressure ring 11 and the mounting block 9 on the corresponding side. The two positioning rods 6 can be driven away from each other by moving the pressure ring 11 downward.

[0026] A clamping mechanism for clamping the liquid level detection sensor 4 is provided at the bottom of the adjusting rod 3. A mounting groove 14 is provided at the bottom of the adjusting rod 3. The liquid level detection sensor 4 is placed in the mounting groove 14. A vertical escape passage 15 is provided in the center of the adjusting rod 3. The connecting line of the liquid level detection sensor 4 is led upward through the escape passage 15. The clamping mechanism includes two groups of clamping components symmetrically arranged on the left and right sides of the mounting groove 14. Each group of clamping components includes a clamping sleeve 16 that can be elastically extended and retracted left and right. The clamping sleeve 16 is an arc-shaped sleeve. The left and right sides of the liquid level detection sensor 4 are clamped by the two clamping sleeves 16. A rubber pad is provided on the opposite side of the two clamping sleeves 16 to avoid damaging the liquid level detection sensor 4 clamped therein, and at the same time, it can increase the friction between the two clamping sleeves 16 and the liquid level detection sensor 4 to ensure the stability of the clamping.

[0027] The clamping assembly also includes a movable rod 17, a compression spring 18, and a support frame 19. The support frame 19 is fixed on the outside of the adjusting rod 3. The movable rod 17 extends in the left and right directions and is slidably supported on the support frame 19. The inner end of the movable rod 17 passes through the adjusting rod 3 and extends into the mounting groove 14 and is fixedly connected to the clamping sleeve 16. The outer end of the movable rod 17 extends out of the support frame 19 and is provided with a handle 20. A limiting ring 21 is provided in the middle section of the movable rod 17. The compression spring 18 is sleeved on the movable rod 17, and the inner and outer ends of the compression spring 18 are respectively connected to the limiting ring 21 and the support frame 19. In the natural state, under the elastic pressure of the compression spring 18, the movable rod 17 is in the inner limit position, so that the two clamping sleeves 16 are close to each other.

[0028] The liquid level detection sensor 4 may be a capacitive intelligent liquid level sensor of model FST700-204. The liquid level detection sensor 4 may be used to know the liquid level of the lubricating oil in the oil tank in real time.

[0029] When installing the liquid level detection sensor 4, pull the two handles 20 outward to drive the two movable rods 17 away from each other, so that the two clamping sleeves 16 are away from each other, and then place the liquid level detection sensor 4 in the installation groove 14, and lead the connecting line of the liquid level detection sensor 4 upward through the avoidance channel 15 of the adjustment rod 3, so that the liquid level detection sensor 4 is located between the two clamping sleeves 16, and then release the two handles 20. Under the action of the two compression springs 18, the two clamping sleeves 16 automatically reset to achieve stable clamping of the liquid level detection sensor 4.

[0030] When the height position of the liquid level detection sensor 4 needs to be adjusted, the pressure ring 11 is first pressed down, and the pressure ring 11 drives the two connecting rods 22 to move synchronously. Since the upper and lower ends of the connecting rod 22 are respectively hinged with the pressure ring 11 and the mounting block 9, the two positioning rods 6 are driven away from each other, so that the inner ends of the two positioning rods 6 are separated from the locking grooves 8 of the adjusting rod 3, and the adjusting rod 3 is unlocked. At this time, the adjusting rod 3 can be moved to adjust its vertical position. After adjustment, the pressure ring 11 is released again. Under the elastic force of the two tension springs 10, the two positioning rods 6 are reset until the inner ends of the two positioning rods 6 are engaged with the locking grooves 8 of the corresponding heights on the left and right sides of the adjusting rod 3. That is, the convenient adjustment of the height position of the liquid level detection sensor 4 is completed, which can meet the liquid level detection requirements of oil tanks of different specifications.

[0031] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
