[0002] The engine oil pump is a device that raises the oil pressure to a certain level in the lubrication system and then delivers the oil to the surfaces of various engine parts. The oil delivery by the engine oil pump ensures excellent lubrication of the engine.

[0003] The engine oil pump cover is a sealing component for the oil pump body, which is usually installed inside the oil pan of the engine. The existing engine oil pump cover is mainly fixed to the pump body through the threaded holes opened on the cover body and external bolts. In order to ensure the normal and safe operation of the oil pump, regular inspection and maintenance are required. Therefore, the threaded holes and bolts on the oil pump cover are prone to repeated rotation and friction, which can easily cause wear due to excessive friction. The worn threaded holes cannot be used anymore, and the cover body needs to be reprocessed or replaced, which affects the normal use of the oil pump, shortens the service life of the oil pump cover, and also increases the cost of using the oil pump cover. Therefore, in order to solve the above problems, an engine oil pump cover is proposed. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] The utility model provides Figure 1-3An engine oil pump cover shown includes a pump cover body 100, which includes a cover body 101, a mounting hole 102 and a threaded hole 103. The mounting hole 102 and the threaded hole 103 are both opened on the cover body 101, and the threaded hole 103 is set on the side of the mounting hole 102. The connecting hole 202 is located below the threaded hole 103, and the connecting hole 202 is connected to the inner cavity of the threaded hole 103. A connecting structure 200 is provided on the pump cover body 100, and the connecting structure 200 includes a connecting plate 201 and a sealing member. The connecting plate 201 is fixedly arranged at the bottom end of the pump cover body 100, and a connecting hole 202 is opened on the connecting plate 201. The sealing member is movably arranged at the bottom end of the connecting plate 201, and the sealing member is used to fasten the position of the pump cover body 100 when it is connected to the engine oil pump body.

[0021] Specific reference Figure 1 and Figure 2 The cover 101 is used in conjunction with the engine oil pump body. The mounting hole 102 opened on the cover 101 is convenient for fitting with the engine oil pump body, and the threaded hole 103 cooperates with the external bolt to fix the cover 101 on the engine oil pump body. The number of threaded holes 103 is multiple, and the specific number is processed according to the actual installation requirements. In this embodiment, the connecting plate 201 is installed and fixed to the bottom of the cover 101 by welding. The inner wall of the connecting hole 202 opened on the connecting plate 201 is provided with an internal thread, so that the external bolt and the screw can be fixed to the cover 101. After the threaded hole 103 is inserted, it can be threadedly connected to the connecting hole 202, thereby providing double protection for the connection between the bolt and the cover body 101. After the threaded hole 103 is worn out due to long-term rotational friction with the bolt, the installation of the connecting plate 201 can be used to provide the bolt with a connection space for the connecting hole 202, thereby making the direct connection between the cover body 101 and the engine oil pump body more secure, and at the same time reducing the probability of replacing the cover body 101, extending the service life of the pump cover body 100, and reducing the replacement cost of the pump cover body 100.

[0022] The sealing component includes a first sealing gasket 203 and a second sealing gasket 204, which are movably connected to each other, and the top of the first sealing gasket 203 is movably connected to the bottom end of the connecting plate 201. A plurality of protrusions are fixedly provided at the bottom end of the first sealing gasket 203, and a plurality of grooves are provided at the top end of the second sealing gasket 204. The plurality of protrusions are respectively embedded in the inner cavities of the plurality of grooves. Double-sided adhesive is fixedly provided between the first sealing gasket 203 and the connecting plate 201, and the first sealing gasket 203 and the second sealing gasket 204 are both elastic rubber.

[0023] Specific reference Figure 2 and Figure 3The first and second sealing gaskets 203 and 204 are provided to strengthen the tightness of the installation connection between the pump cover body 100 and the engine oil pump body. Because the first and second sealing gaskets 203 and 204 are made of elastic rubber material, when the pump cover body 100 is connected to the engine oil pump body, the first and second sealing gaskets 203 and 204 can be used to increase the friction between the pump cover body 100 and the engine oil pump body. The first and second sealing gaskets 203 and 204 are connected by the embedding of the protrusions and the grooves. Because the second sealing gasket 204 is located between the pump cover body 100 and the engine oil pump body when they are connected, the friction loss suffered by the second sealing gasket 204 is greater than the friction loss suffered by the first sealing gasket 203. 04 is replaced more frequently than the first gasket 203, and a detachable structure is embedded between the first gasket 203 and the second gasket 204, which facilitates the disassembly and replacement of the second gasket 204, effectively improving the convenience and flexibility of replacing the second gasket 204. At the same time, the first gasket 203 and the connecting plate 201 are installed and fixed by double-sided adhesive, so that the first gasket 203 and the connecting plate 201 can also be replaced. Through the setting of the first gasket 203 and the second gasket 204, it is also possible to avoid damage to the connecting plate 201 and the engine oil pump body due to friction, effectively improving the safety of the use of the connecting plate 201, and further enhancing the effectiveness and firmness of the installation and fixation of the pump cover body 100 and the engine oil pump body.

[0024] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
