AI Technical Summary
The existing oil-injection engine oil drum seals do not fit closely with the inner wall of the oil drum, resulting in poor sealing effect. The sealing ring is not suitable for oil drums of different sizes, and is poor in practicality.
A seal is designed including a first oil pressure pan, a second oil pressure pan and an inflatable sealing ring. Through the first air intake hole, the second air intake hole and the air outlet hole, gas is transported to the inflatable sealing ring, which expands and closely fits into the inner wall of the oil barrel. At the same time, by controlling the gas output, the sealing ring is adapted to the oil barrel of different sizes.
The sealing effect of the seal is improved and adapted to oil barrels of different sizes, which significantly improves the practicality of the seal.

Description
Technical Field
[0001] The utility model relates to the technical field of sealing components, in particular to an oil barrel sealing component for an oil filling machine. Background Art
[0002] Oiling machines are mainly used to transport lubricating oil in the lubrication systems of various mechanical equipment. The products are widely used in the lubrication systems of mechanical equipment in various industries such as CNC machinery, machining centers, elevators, production lines, machine tools, forging, casting, textiles, plastics, woodworking, rubber, mining, metallurgy, construction, printing, food, etc., as well as centralized lubrication systems of automobile chassis.
[0003] Most of the existing oil barrel seals for oil filling machines use traditional sealing rings to seal the oil barrels. This sealing method cannot fit tightly with the inner wall of the oil barrel, resulting in poor sealing effect. At the same time, the sealing ring is not suitable for oil barrels of different sizes and has poor practicality. Therefore, we propose an oil barrel seal for oil filling machines.

[0006] Preferably, the first air inlet hole is connected to the second air inlet hole and the air outlet hole, and the aperture of the first air inlet hole is larger than that of the second air inlet hole.
[0007] Preferably, the inflatable sealing ring is made of rubber material, and the inside of the inflatable sealing ring is hollow.
[0008] Preferably, the top of the inner surface edge of the inflatable sealing ring is arranged in a trapezoidal protrusion.
[0009] Preferably, the inflatable sealing ring is located between the first oil pressure plate and the third oil pressure plate.
[0010] Compared with the prior art, the beneficial effects of the utility model are as follows: first, the gas will be output from the first air inlet hole to the second air inlet hole, and then the second air inlet hole will output the gas to the inflatable sealing ring through the air outlet hole, thereby expanding the inflatable sealing ring and fitting tightly against the inner wall of the oil barrel, thereby improving the sealing effect of the seal, and at the same time, controlling the output of gas to the inside of the inflatable sealing ring, so that the seal can adapt to oil barrels of different sizes, thereby improving the practicability of the seal.

[0018] Furthermore, the first air inlet hole 11 is connected to the second air inlet hole 31 and the air outlet hole 32, and the aperture of the first air inlet hole 11 is larger than that of the second air inlet hole 31. The gas enters the second air inlet hole 31 from the first air inlet hole 11, and then inflates into the inflatable sealing ring 4 from the second air inlet hole 31 through the air outlet hole 32.
[0019] Furthermore, the inflatable sealing ring 4 is made of rubber, and the inside of the inflatable sealing ring 4 is hollow, so air can be inflated into the hollow inflatable sealing ring 4 .
