Abstract
Description
Technical Field
[0001] The utility model belongs to the field of engines and relates to an oil pan at the bottom of an engine cylinder body. Background Art
[0002] In the engine lubrication system, the engine oil pan plays a vital role. It is not only used to seal the crankcase, but also carries the storage and recovery functions of the engine oil to ensure that the engine components are continuously lubricated. However, as the engine runs longer, various impurities will gradually mix into the engine oil. These impurities mainly come from the wear and tear during the manufacturing process, assembly process or operation of the engine, such as iron filings, burrs, welding, rust, etc. The presence of these impurities will seriously affect the lubrication performance of the engine oil and even aggravate the wear of the engine, thereby affecting the overall performance and life of the engine. At present, in order to solve this problem, the drain bolt is made of magnets to absorb impurities in the engine oil. However, due to the relatively small size of the drain bolt, its adsorption capacity and speed are subject to certain limitations, resulting in poor adsorption effect. Utility Model Content

[0010] Compared with the prior art, the utility model has the following beneficial effects:
[0011] Firstly, the utility model uses the magnet strip on the oil guide cover to make the impurities in the oil flow along the oil guide cover quickly and efficiently, thereby preventing the impurities from affecting the lubricating performance of the oil;
[0012] Secondly, the oil guide cover can also prevent the oil in the oil pan from agitating, so that there is always sufficient oil at the bottom of the oil suction tank for the oil suction pump to suck and lubricate;
[0013] Thirdly, the anti-scouring oil retaining strip can prevent the dripping oil from directly washing away the impurities on the magnet strip, thereby preventing the impurities from being mixed into the engine oil again and affecting lubrication. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0019] The following is a further detailed description of an oil pan at the bottom of an engine cylinder block proposed by the utility model in combination with the accompanying drawings and specific embodiments. According to the following description, the advantages and features of the utility model will become clearer. It should be noted that the accompanying drawings are all in a very simplified form and are not in precise proportions, which are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the utility model. The same or similar reference numerals in the accompanying drawings represent the same or similar components.
[0020] Example, see Figure 1-4An oil pan at the bottom of an engine cylinder block includes an oil pan 1 with an opening at the upper end, a circle of mounting edges 2 is arranged at the edge of the upper end of the oil pan 1, and a plurality of mounting holes 3 are arranged through the mounting edges 2. A plurality of heat dissipation fins 4 are arranged at the bottom of the oil pan 1, and the heat dissipation fins 4 can dissipate the oil more quickly to prevent the oil temperature from being too high. The bottom of one end of the oil pan 1 is recessed downward to form an oil suction groove 5, and an oil drain hole 6 with internal threads connected to the bottom of the oil suction groove 5 is opened inwardly on the outer side of the oil pan 1. An oil drain bolt 7 is threadedly connected to the oil drain bolt 7, and a bolt head 8 is arranged at the outer end of the oil drain bolt 7. A circle of sealing rubber ring 9 is arranged on the side of the bolt head 8 close to the oil drain bolt 7 to prevent oil leakage from the oil drain hole 6.
[0021] An oil guide cover 10 with a small upper end and a large lower end is provided at the upper end of the oil suction groove 5. There is a gap between the lower end of the oil guide cover 10 and the bottom of the oil suction groove 5. An oil suction inlet 11 is opened at the upper end of the oil guide cover 10. The oil suction pipe of the oil suction pump is put into the bottom of the oil suction groove 5 from the oil suction inlet 11. The outer wall of the oil guide cover 10 is provided with a plurality of magnet strips 12 inclined from top to bottom. The magnet strips 12 are used to absorb impurities in the engine oil. An anti-scouring oil blocking strip 13 is provided at the upper end of each magnet strip 12 to prevent the engine oil pouring from the engine cylinder from washing away the impurities adsorbed on the magnet strip 12. The edge of the oil guide cover 10 is provided with a circle of connecting edges 14 connected to the inner wall of the oil suction groove 5. A plurality of oil leakage holes 15 are opened at the edge of the connecting edge 14, and each oil leakage hole 15 is directly opposite to the gap between the two magnet strips 12.
[0022] Working principle: The oil pump pumps the engine oil from the bottom of the oil suction groove 5 to various positions of the engine for lubrication. The engine oil dripping from the engine cylinder body falls on the oil guide cover 10 or the bottom of the oil pan 1. The engine oil on the oil guide cover 10 slides downward along the magnet bar 12. During the process, impurities in the engine oil are quickly adsorbed by the magnet bar 12. At the same time, the anti-scouring oil baffle 13 prevents the dripping oil from directly washing away the impurities on the magnet bar 12. Finally, the engine oil at the bottom of the oil guide cover 10 and the oil pan 1 falls into the bottom of the oil suction groove 5 along the oil leakage hole 15 and is sucked and used again by the oil suction pump.
[0023] It should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
[0024] The above description is only a description of the preferred embodiment of the utility model, and is not any limitation on the scope of the utility model. Any changes and modifications made by ordinary technicians in the field of the utility model based on the above disclosure shall fall within the scope of protection of the claims.
