However, for a six-cylinder engine, its intake pipe is long and has intake on one side. When spraying oil seal oil, the distances between each cylinder and the spray port of the air spray gun are inconsistent. The farther the distance, the less oil seal oil is sprayed. This results in uneven spraying of oil seal oil, unable to effectively protect the internal parts of the engine, causing engine rust, and in severe cases, the engine cannot be used, thus shortening the service life of the engine.

[0004] Therefore, how to extend the service life of the engine is a technical problem that needs to be solved urgently by those skilled in the art. Summary of the Utility Model

[0034] The core of the present invention is to provide an engine oil seal device to extend the service life of the engine.

[0035] To enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0036] Please refer to Figures 1 to 8 .

[0037] In a specific embodiment, the engine oil seal device provided by the specific embodiment of the present utility model includes a spray pipe 2 and a mounting table 4. The first end of the spray pipe 2 is blocked, and the second end of the spray pipe 2 is open.

[0038] As Figure 2 shown, the mounting table 4 is connected to the second end of the spray pipe 2. The mounting table 4 is provided with a mounting position for connecting to a spray gun, where the spray gun and the mounting table 4 can be non-detachably connected. Preferably, the spray gun and the mounting table 4 are detachably connected. Specifically, the mounting table 4 is connected to the spray gun through fasteners. To reduce the number of connecting components, preferably, the spray gun and the mounting table 4 are threadedly connected, that is, the mounting position is provided with a threaded mounting position, and the spray gun is threadedly connected to the threaded mounting position.

[0039] The inner cavity of the spray pipe 2 is provided with an oil injection channel 201 communicating with the opening. The oil injection channel 201 is used to accommodate the oil seal oil of the spray gun, and the spray gun can be an air spray gun. The oil injection channel 201 is a slender hollow pipeline to ensure sufficient pressure to spray out the oil seal oil. The spray pipe 2 is sequentially provided with a plurality of spray groups 3 along the flowing direction of the oil seal oil in the oil injection channel 201. The spray group 3 includes an oil seal hole 301. As Figure 4 shown, each spray group 3 can be provided with one oil seal hole 301. Preferably, when the spray pipe 2 is inserted into the intake pipe, the oil seal hole 301 is aligned with the cylinder of the engine.

[0040] The number of spray groups 3 is the same as the number of cylinders of the engine, and they are arranged in one-to-one correspondence. Preferably, the distance between the central positions of adjacent two spray color groups is equal to the distance between the central positions of adjacent two cylinders.

[0041] In a specific embodiment, the spray group 3 is provided with at least two oil seal holes 301, and the oil seal holes 301 are arranged around the outer circumference of the spray pipe 2.

[0042] As Figure 5 shown, each spray group 3 includes four oil seal holes 301, and the four oil seal holes 301 are evenly distributed around the circumference of the spray pipe 2 to ensure the oil seal atomization effect, and the corresponding number of positions are selected according to the number of engine cylinders. Specifically, two spray holes are drilled at 180° up and down at the same part of the spray pipe 2 along the flowing direction of the oil seal oil, and then after rotating 90°, two spray holes are drilled at 180° up and down at another position to form four oil seal holes 301.

[0043] As Figure 6As shown in the figure, in order to expand the spraying range of the oil seal hole 301, preferably, the oil seal hole 301 is a tapered hole, and the cross-sectional area of the oil seal hole 301 gradually increases along the oil spraying direction.

[0044] When the engine needs to be oil sealed continuously, the mounting table 4 is connected to the spray gun, the spray pipe 2 is inserted into the intake pipe, and the oil seal oil in the spray gun is sprayed into the corresponding cylinder and intake pipe of the engine through the spray pipe 2 and the spray group 3.

[0045] As can be seen from the above description, in the engine oil seal device provided in the specific embodiment of the present application, through the spray pipe 2 connected to the spray gun, by providing a spray pipe inserted into the intake pipe, and the number of spray groups 3 is the same as the number of cylinders of the engine and they are arranged in one-to-one correspondence, so that each cylinder in the engine is evenly oil sealed, reducing the rust problem caused by uneven spraying, and thus extending the service life of the engine.

[0046] In order to improve the spraying effect, preferably, the length of the spray pipe 2 is equal to the length of the intake pipe of the engine. When the spray pipe 2 is located in the intake pipe of the engine, the first end of the spray pipe 2 abuts against the end of the intake pipe of the engine.

[0047] In the present application, by providing the spray pipe 2, the spraying length of the spray gun is extended. With multiple groups of spray groups 3 designed for spraying, after the overall installation is completed, only this oil seal device needs to be extended into the internal intake pipe. When the first end of the spray pipe 2 abuts against the end of the intake pipe of the engine, it indicates that the spray pipe 2 is installed in place, and then the oil seal operation can be carried out. No matter what angle the operator uses for the oil seal operation, it can ensure that oil seal oil is atomized and sprayed out along with the air pressure in each section, so that the engine is evenly oil sealed, effectively solving the problem of uneven spraying, reducing rust, and extending the storage time of the engine.

[0048] Considering that the spray pipe 2 needs to move a certain distance when entering the intake pipe, in order to prevent the spray pipe 2 from scratching the inner wall of the intake pipe during the movement, preferably, the outer wall of the first end of the spray pipe 2 is an arc structure. For example, the first end of the spray pipe 2 is a spherical surface, or other arc surface structures, etc.

[0049] As Figure 3 As shown in the figure, in a specific embodiment, the engine oil seal device further includes a first positioning portion 1, the first positioning portion 1 is connected to the first end of the spray pipe 2, and a second positioning portion adapted to the first positioning portion 1 is provided at the end of the intake pipe. When the first positioning portion 1 and the second positioning portion are adapted, the oil seal hole 301 is aligned with the cylinder of the engine. At this time, it can be ensured that the positions of the oil seal hole 301 and the holes connecting each cylinder to the intake pipe are consistent.

[0050] One of the first positioning portion 1 and the second positioning portion can be a plate structure, and the other can be a hole structure. As Figure 7As shown, the first positioning portion 1 is a rectangular block. At this time, the first positioning portion 1 is a plate structure, and the second positioning portion is located in a rectangular groove adapted to the rectangular block. Since it is a rectangular structure, it is ensured that when the first positioning portion 1 and the second positioning portion are adapted, the oil seal hole 301 is aligned with the cylinder of the engine.

[0051] As Figure 8 shown, the first positioning portion 1 includes a mounting block 101 and a positioning block 102 connected to the mounting block 101. The second positioning portion is a positioning groove adapted to the first positioning portion 1. With such a setting, when the first positioning portion 1 is exactly engaged in the positioning groove, the oil seal hole 301 is aligned with the cylinder of the engine. Specifically, the mounting block 101 can be a circular block.

[0052] To improve the assembly efficiency, preferably, the first positioning portion 1 and the injection pipe 2 are integrally formed. Specifically, after the first positioning portion 1 and the injection pipe 2 are formed by casting, the oil seal hole is processed. Alternatively, the ends of the first positioning portion 1 and the injection pipe 2 are sealed by threaded connection.

[0053] Of course, the mounting table 4 and the injection pipe 2 can also be an integrally formed structure. Preferably, the outer periphery of the mounting table 4 is an annular structure that fits the inner wall of the intake end of the intake pipe, so as to position the injection pipe 2 after the injection pipe 2 extends into the intake pipe.

[0054] To facilitate the smooth flow of the oil seal oil in the injection pipe, preferably, the injection passage 201 is a straight bar-shaped passage. Specifically, the injection passage 201 can be a square passage, a rectangular passage, a cylindrical passage, etc. For ease of processing, preferably, the injection passage 201 is a cylindrical passage.

[0055] The engine oil seal device provided by the present application replaces the nozzle of the traditional spray gun and is used as a new nozzle. The overall structure is simple, the versatility is good, and the cost performance is high. A very small cost increase can solve major technical problems, and it is suitable for wide promotion and application.

[0056] Finally, it should also be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0057] The various embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0058] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present utility model. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present utility model. Therefore, the present utility model will not be limited to the embodiments shown herein, but rather to the broadest scope consistent with the principles and novel features disclosed herein.
