[0003] For example, the patent number CN220185241U is an oil-leakage-proof valve cover, which includes a cover body and an anti-leakage mechanism arranged at the bottom end of the cover body, wherein the mechanism includes a first connecting component, a second connecting component and a sealing component; the first connecting component includes a connecting hole and a first connecting plate, the top end of the cover body is provided with a connecting hole, and the bottom edge of the cover body is welded with a first connecting plate; the above document still has shortcomings. When in use, by setting a sealing cavity, the first connecting plate and the second connecting plate are tightly fitted, and the first sealing ring and the second sealing ring are used to form a sealing state in the sealing cavity at the connection part of the first connecting plate and the second connecting plate, thereby improving the sealing of the first connecting plate and the second connecting plate and avoiding oil leakage. However, the cover body in the above document is covered on the top of the air chamber to prevent oil leakage. When the air chamber moves with the vehicle, the cover body and the air chamber are easily separated in a state without a locking function, thereby causing oil leakage. At the same time, the air chamber in the above document is opaque, which makes it difficult to find out in time when the oil amount in the air chamber is insufficient. Utility Model Content

The structures and principles of the connecting block 11, the heat absorbing plate 12 and the heat sink 13 are the same as those in an oil leakage-proof valve cover with patent number CN220185241U.

[0024] The anti-leakage mechanism 3 includes a connecting ring 301, a rope body 302, a round cover 303, a locking rod 304, a disc 305, a notch groove 306 and a cylinder 307. The connecting ring 301 is fixedly connected to the outer wall of the second connecting plate 6. The connecting ring 301 moves together with the second connecting plate 6. The connecting ring 301 is fixedly connected to one end of the rope body 302. The rope body 302 tightens the connecting ring 301. The other end of the rope body 302 is fixedly connected to the round cover 303. The rope body 302 tightens the round cover 303. Two locking rods 304 are fixedly connected to the bottom of the round cover 303. The round cover 303 drives the two locking rods 304 to rotate.

[0025] The locking rod 304 is clamped with the outer wall of the disc 305. The locking rod 304 is clamped with the outer wall of the disc 30. The disc 305 is provided with a notch groove 306 inside. The notch groove 306 facilitates the separation of the locking rod 304 and the disc 305. A cylinder 307 is fixedly connected below the disc 305. The cylinder 307 supports and fixes the disc 305. The cylinder 307 is fixedly connected to the upper surface of the horizontal plate 2.

[0026] Hold the round cover 303 so that the two locking rods 304 correspond to the positions of the two notched grooves 306, press the round cover 303 downward, the lower ends of the two locking rods 304 are located below the disc 305 through the notched grooves 306, rotate the round cover 303, and the round cover 303 drives the locking rods 304 to rotate, the locking rods 304 are away from the positions of the notched grooves 306, the locking rods 304 are engaged with the disc 305, and the position of the round cover 303 is fixed. The round cover 303 fixes the position of the cover body 10 through the rope body 302 and the connecting ring 301. The cover body 10 and the air chamber 1 are not easily separated in a state with a locking function, and oil leakage will not occur.

[0027] The observation mechanism 4 includes a transparent tube 401, scale lines 402, a ring 403 and a screw 404. The outer wall of the end of the transparent tube 401 is fixedly connected to the air chamber 1. The transparent tube 401 is connected to the air chamber 1. The surface of the transparent tube 401 is provided with scale lines 402. The scale lines 402 facilitate observation of the liquid level of the oil in the transparent tube 401. The outer wall of the transparent tube 401 is slidably connected to the ring 403. The ring 403 slides on the outer wall of the transparent tube 401. The inner thread of the ring 403 is connected to the screw 404. The end of the screw 404 is pressed against the transparent tube 401 to fix the ring 403 on the outer wall of the transparent tube 401.

[0028] The liquid level of the oil in the transparent tube 401 is the same as the liquid level height of the oil in the air chamber 1. The scale line 402 is used to observe the liquid level of the oil. The sliding ring 403 slides on the outer wall of the transparent tube 401 so that the ring 403 is at the oil level where the oil is insufficient and needs to be supplemented. The screw 404 is turned and the screw 404 fixes the ring 403 on the outer wall of the transparent tube 401. When the liquid level of the oil in the transparent tube 401 is lower than the ring 403, it means that the oil needs to be supplemented in the air chamber, so that it is easy to find out in time when the oil in the air chamber 1 is insufficient.

[0029] Working principle:

[0030] When the oil-leakage-proof valve cover is in use, the air chamber 1 is filled with oil, the cover body 10 covers the air chamber 1, the second connecting plate 6 is fitted with the outer wall of the first connecting plate 5, and the first sealing ring 7 and the second sealing ring 8 increase the sealing between the first connecting plate 5 and the second connecting plate 6 to prevent oil leakage;

[0031] Cover locking stage:

[0032] After the cover body 10 is buckled on the top of the air chamber 1, the round cover 303 is held, the two locking rods 304 are aligned with the positions of the two notches 306, and the round cover 303 is pressed downward. The lower ends of the two locking rods 304 are located below the disc 305 through the notches 306. The round cover 303 is rotated, and the round cover 303 drives the locking rods 304 to rotate. The locking rods 304 are away from the notches 306, and the locking rods 304 are engaged with the disc 305, thereby fixing the position of the round cover 303. The round cover 303 fixes the position of the cover body 10 through the rope body 302 and the connecting ring 301. The cover body 10 and the air chamber 1 are not easily separated in a locked state, and oil leakage will not occur.

[0033] Air chamber use stage:

[0034] The heat absorbing sheet 12 absorbs the heat in the air chamber 1, and the heat sink 13 dissipates the heat absorbed by the heat absorbing sheet 12. The oil level in the transparent tube 401 is the same as the oil level in the air chamber 1. The scale line 402 is used to observe the oil level. The sliding ring 403 slides on the outer wall of the transparent tube 401 so that the ring 403 is at the oil level where the oil is insufficient and needs to be supplemented. The screw 404 is turned and the screw 404 fixes the ring 403 on the outer wall of the transparent tube 401. When the oil level in the transparent tube 401 is lower than the ring 403, it means that the oil needs to be supplemented in the air chamber, and it is easy to find out in time when the oil in the air chamber 1 is insufficient.

[0035] Example 2: Refer to the attached Figure 1-6: In this embodiment, a valve cover for preventing oil leakage, the anti-leakage mechanism 3 also includes a spring 3a1 and a circular plate 3a2. The model of the spring 3a1 is selected according to the actual implementation needs and can meet the working needs. The upper end of the spring 3a1 is fixedly connected to the circular cover 303. The spring 3a1 can drive the circular plate 3a2 to move under the elastic action, and the lower end of the spring 3a1 is fixedly connected to the circular plate 3a2.

[0036] Through the cooperation between the spring 3a1 and the circular plate 3a2, when the locking rod 304 is clamped on the outer wall of the disk 305, the lower end of the circular plate 3a2 fits against the disk 305, and the spring 3a1 is compressed. The spring 3a1 can drive the circular plate 3a2 to move under the elastic action, thereby making the round cover 303 have the force to move away from the disk 305, thereby increasing the stability of the clamping between the locking rod 304 and the disk 305.

[0037] Working principle:

[0038] When the locking rod 304 is engaged with the outer wall of the disc 305, the lower end of the circular plate 3a2 fits against the disc 305, and the spring 3a1 is compressed. The spring 3a1 can drive the circular plate 3a2 to move under the elastic action, thereby causing the circular cover 303 to have the force to move away from the disc 305, thereby increasing the stability of the engagement between the locking rod 304 and the disc 305.
