AI Technical Summary
During the long rotation of the engine cylinder head, the gap is easily generated, causing the lubricating oil inside the cylinder to slowly flow out from the gap, causing leakage.
A leak-proof engine cylinder head is designed, with an inner groove and a shaft opening inside, and an oil removal component is provided in the shaft opening, including a rotating ring, a scraper and a restricting groove. The rotary ring is slidally connected to the shaft port, the scraper is installed inclinedly, and the bottom of the restriction groove is a triangular cut surface. When the lubricant oil falls into the restriction groove, the scraper rotates and throws it back into the inner groove to avoid leakage.
The lubricant is thrown back into the inner groove through the scraper, effectively preventing the lubricant from leaking from the shaft opening and solving the problem of oil leakage on the cylinder head.

Abstract
Description
Technical Field
[0001] The utility model belongs to the field of cylinder covers, and in particular relates to a leak-proof engine cylinder cover. Background Art
[0002] The cylinder head is installed on the top of the cylinder block, sealing the cylinder from the top and forming the combustion chamber. The cylinder head is also equipped with intake and exhaust valve seats, valve guide holes for installing intake and exhaust valves, and intake and exhaust channels. The cylinder head of a gasoline engine is machined with holes for installing spark plugs, while the cylinder head of a diesel engine is machined with holes for installing injectors. The cylinder head of an overhead camshaft engine is also machined with camshaft bearing holes for installing the camshaft.
[0003] At the location where the rotating shaft is installed, a gap will inevitably be generated due to its long-term rotation. At this time, the lubricating oil inside the cylinder will slowly flow out of this gap, causing leakage. Utility Model Content
[0004] The utility model aims at the deficiencies of the prior art and provides a leak-proof engine cylinder cover.
[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a leak-proof engine cylinder head, comprising a cylinder head, an inner groove is provided inside the cylinder head, and the characteristics are: an axis opening is provided at the center of the inner groove, and an oil removal component is provided inside the axis opening;
[0006] The oil removal assembly comprises a swivel rotating in the shaft opening, the swivel is provided with a connecting ring via a connecting shaft, at least two scrapers are provided on the connecting ring, and the scrapers are installed at an angle.
[0007] Optionally, a limiting groove is further provided at the bottom of the inner groove, and the cross-section of the limiting groove is triangular.
[0008] Optionally, the scraper is in close contact with a side of the limiting groove away from the shaft opening.
[0009] Optionally, the swivel is located on a side of the shaft opening close to the inner groove, and a surface of the swivel is higher than a plane of the shaft opening, and a sliding connection is formed between the swivel and the shaft opening.
[0010] In summary, compared with the prior art, the present invention has the following beneficial effects:
[0011] 1. Due to the setting of the oil removal component, the lubricating oil inside the limiting groove can be thrown back into the inner groove through the scraper to prevent the lubricating oil from continuing to leak out from the shaft mouth, effectively avoiding oil leakage from the cylinder head.

[0016] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.
[0017] As shown in Figure 1-3, a leak-proof engine cylinder head includes a cylinder head 10, an inner groove 11 is opened inside the cylinder head 10, an axial opening 12 is opened at the center of the inner groove 11, an oil removal component is arranged inside the axial opening 12, and the oil removal component includes a swivel 13 rotating in the axial opening 12, the swivel 13 is located on the side of the axial opening 12 close to the inner groove 11, and the surface of the swivel 13 is higher than the plane of the axial opening 12, the swivel 13 and the axial opening 12 are slidably connected, the swivel 13 is installed with a connecting ring 16 through a connecting shaft 17, and at least two scrapers 14 are arranged on the connecting ring 16, and the scrapers 14 are installed at an angle, and a limiting groove 15 is also opened at the bottom of the inner groove 11, and the cross-section of the limiting groove 15 is set in a triangle, and the scraper 14 is tightly attached to the side of the limiting groove 15 away from the axial opening 12.
[0018] When in use, the cylinder head 10 is directly installed on the cylinder body, the rotating shaft in the cylinder body will pass through the shaft opening 12, and the bearing thereon will have an interference fit with the shaft opening 12, while the bearing will not abut against the swivel 13. The swivel 13 abuts against the rotating shaft. When the rotating shaft rotates, the swivel 13 will be driven to rotate. The rotation of the swivel 13 drives the connecting ring 16 to rotate through the connecting shaft 17, thereby driving the scraper 14 to rotate. When the lubricating oil inside the cylinder body falls into the limiting groove 15, due to the triangular setting of the limiting groove 15, the lubricating oil will fall into the limiting groove 15. At this time, the rotation of the scraper 14 will scratch the lubricating oil in the limiting groove 15, and the lubricating oil inside the limiting groove 15 will be thrown back into the inner groove 11 to prevent the lubricating oil from continuing to leak out from the shaft opening 12, thereby effectively preventing oil leakage from the cylinder head.
[0019] Obviously, the described embodiments are only a part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
