[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] Referring to Figure 1 - Figure 3 , an embodiment provided by the present invention: a quickly rotatable oil tank cover, which includes an oil tank 1. A cover plate 2 is slidably connected to the top end of the oil tank 1. The sliding connection method allows the cover plate 2 to slide smoothly on the top end of the oil tank 1, so as to facilitate opening and closing. A turning handle 3 is rotatably connected to the inner wall of the cover plate 2. When the operator rotates the turning handle 3, it rotates accordingly and drives the subsequent components to rotate, thereby driving the opening and closing mechanism of the entire oil tank cover. A disc 4 is fixedly connected to the bottom side of the turning handle 3 to limit the turning handle 3 and prevent it from slipping. Two support columns 5 are fixedly connected to the top side of the inner wall of the cover plate 2 to provide support force for the subsequent components. A circular plate 6 is fixedly connected to the bottom side of the two support columns 5 to provide a support platform;

[0033] Square frames 7 are fixedly connected to the left and right ends of the top side of the circular plate 6 to limit the subsequent components from making linear displacement. Rotating components for driving the subsequent components to displace are fixedly connected to both the left and right sides of the turning handle 3. The rotating component includes side plates 8. The left and right sides of the turning handle 3 are respectively fixedly connected to the adjacent sides of the two side plates 8. When the turning handle 3 rotates, the side plates 8 will drive the subsequent components to displace, thereby realizing the preliminary movement of the opening and closing of the oil tank cover. Rotating plates 9 are rotatably connected to the far ends of the two side plates 8 to transmit the force of the rotation of the side plates 8 to the rotating plates 9. Open blocks 10 are rotatably connected to the far ends of the two rotating components. Fixed plates 11 are fixedly connected to the far sides of the two open blocks 10 for passing through the oil tank 1 and engaging inside the cover plate 2.

[0034] Referring to Figure 2 - Figure 4, the outer parts of the two fixing plates 11 are respectively slidably connected to the left and right ends of the top of the oil tank 1 to restrict the oil tank 1. The outer parts of the two fixing plates 11 are respectively slidably connected to the inner walls of the left and right ends of the cover plate 2 to fix the cover plate 2 and complete the connection between the oil tank 1 and the cover plate 2. The far ends of the two rotating plates 9 are respectively fixedly connected to the inner walls of the two opening blocks 10 to restrict the rotating plates 9 so that the rotating plates 9 can rotate. The outer part of the fixing plate 11 is slidably connected to the inner wall of the square frame 7 so that the fixing plate 11 can perform linear displacement. The bottom side of the fixing plate 11 is fixedly connected to an adapter block 12 to transmit the force of the linear displacement to the adapter block 12. The inner wall of the adapter block 12 is slidably connected to a fixing rod 13 to restrict the adapter block 12 so that the adapter block 12 can slide horizontally. A first spring 14 is sleeved on the outer part of the fixing rod 13 to restrict the first spring 14 so that the first spring 14 can be evenly stressed. A fixing ring 15 is fixedly connected to the top end of the inner wall of the oil tank 1 to provide a supporting force.

[0035] Referring to Figure 1 , Figure 2 and Figure 5 , both the front and rear ends of the top side of the circular plate 6 are fixedly connected with strip plates 16 to provide a supporting force for the strip plates 16. A reset assembly for resetting subsequent components is fixedly connected to the top end of the inner wall of the strip plates 16. The reset assembly includes a fixing rod 17. The outer part of the fixing rod 17 is fixedly connected to the top end of the strip plate 16. A second spring 18 is sleeved on the outer part of the fixing rod 17 to restrict the second spring 18 so that the second spring 18 can be stressed. Triangular blocks 19 are slidably connected to both the left and right ends of the reset assembly. The adjacent sides of every two triangular blocks 19 are respectively fixedly connected to the left and right ends of one of the second springs 18 to transmit the reset force to the triangular blocks 19. The inner walls of every two triangular blocks 19 are respectively slidably connected to the left and right end inner walls of one of the fixing rods 17 so that the triangular blocks 19 can slide horizontally;

[0036] T-shaped openings 20 are formed in the far sides of every two triangular blocks 19 to restrict the displacement of subsequent components. A sliding rod 21 is slidably connected to the inner wall of the triangular block 19 to achieve force transmission. L-shaped plates 22 are fixedly connected to the far sides of every two sliding rods 21. The top ends of the L-shaped plates 22 are slidably connected to the inner wall of the triangular block 19. Connecting plates 23 are fixedly connected to the bottom sides of every two L-shaped plates 22 to provide a supporting force for the L-shaped plates 22. Square blocks 24 are fixedly connected to both the left and right ends of the bottom side of the connecting plate 23 to restrict the square blocks 24 to prevent the square blocks 24 from falling. The outer parts of multiple square blocks 24 are respectively slidably connected to the inner walls of the four corners of the circular plate 6. A sealing plate 25 is fixedly connected to the bottom side of multiple square blocks 24. The bottom side of the sealing plate 25 is in contact with the top side of the fixing ring 15 to improve the overall sealing performance of the device. Limit blocks 26 are fixedly connected to both the front and rear sides of the top end of the oil tank 1 to facilitate the clamping and sliding with the cover plate 2.

[0037] Working principle: By holding the throttle grip 3 and applying a rotational force, the throttle grip 3 will drive the two side plates 8 to rotate, thereby driving the two rotating plates 9 to displace and rotate. The two rotating plates 9 are respectively restricted by the opening blocks 10, and the square frame 7 is restricted by the fixing plate 11, causing the fixing plate 11 to perform a linear displacement. When the rotating plate 9 rotates, it will drive the opening block 10 to rotate and displace and drive the fixing plate 11 to slide horizontally. During the sliding process of the fixing plate 11, it will drive the connecting block 12 to slide and squeeze the fixing rod 13, enabling the fixing rod 13 to store elastic potential energy, and then giving the connecting block 12 a force in the opposite direction. Then, it will push the fixing plate 11 to slide and engage inside the cover plate 2. When the two fixing plates 11 slide out of the inside of the cover plate 2 respectively, and then slide out of the inside of the oil tank 1, at this time, by holding the handle on the top side of the cover plate 2, the cover plate 2 can be quickly opened and closed without repeatedly rotating complex threads, thereby improving work efficiency;

[0038] When the cover plate 2 is covered on the oil tank 1, the cover plate 2 will drive the sealing plate 25 to fit with the fixing ring 15. After the sealing plate 25 contacts the fixing ring 15 and as the cover plate 2 continues to press down, the sealing plate 25 will receive a reaction force at this time, and then transmit the force to multiple square blocks 24. Through the two pairs of square blocks 24, both will push the connecting plate 23 to slide. Each connecting plate 23 will push two L-shaped plates 22 to slide, and the L-shaped plates 22 will drive the sliding rod 21 to slide and exert a thrust against the triangular block 19. At this time, the vertical force received by the triangular block 19, due to the inclined surface where it fits with the sliding rod 21, after the vertical force is transmitted to the triangular block 19, the triangular block 19 will perform a horizontal displacement and slide. Then, each pair of triangular blocks 19 will slide towards the adjacent side and push and squeeze the second spring 18. At this time, the second spring 18 will store elastic potential energy, and then the rebounding force will be transmitted to the sealing plate 25 through multiple components, enabling the sealing plate 25 to fit more tightly with the fixing ring 15, thereby improving the sealing performance of the device.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
