Description

Technical Field

[0001] The utility model relates to the technical field of engines, in particular to an engine lubrication system. Background Art

[0002] The engine lubrication system is equipped with an oil filter at the inlet of the lubricating oil. The oil filter can filter the impurities in the engine lubricating oil, so as to avoid scratches on the relative sliding joint surfaces of the internal moving parts of the engine due to excessive impurities in the lubricating oil, causing the moving parts to fail and further affecting the failure of the whole machine. The current oil filter is composed of a body, a filter, a clamping hole, a sealing ring and other parts. The filter usually uses a high-density mesh structure, the body is made of injection molding materials, and the body and the filter are integrally injection molded. Install the sealing ring in the sealing ring groove of the body and it can be installed as a whole on the engine for use.

[0003] However, due to the limited structural space of the engine oil filter, the filter seat and filter body are generally made of integral injection molding. Therefore, they must be replaced as a whole after long-term use, which increases costs and causes waste of materials. In addition, when the oil temperature is too high after the engine is running, specifically up to 135°C or above, the size of the filter seat will be deformed due to the high temperature, so that the sealing ring cannot be well sealed, resulting in oil leakage. Utility Model Content

[0004] The purpose of the utility model is to provide an engine lubrication system to solve the problems in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] An engine lubrication system comprises an oil filter body and an oil filter seat, wherein a connecting portion is provided at one end of the oil filter body, a connecting port matched with the connecting portion is provided at one end of the oil filter seat, a sealing groove is provided on the outer ring of the connecting port, a sealing ring is sleeved on the sealing groove, a groove is provided inside the connecting port, a convex strip matched with the groove is provided outside the connecting portion, and an internal control barb is provided inside the oil filter seat.

[0007] Furthermore, the oil filter body is provided with a filter screen and an oil outlet.

[0008] Furthermore, a knob is provided at the other end of the oil filter seat.

[0009] Furthermore, a fixing portion is provided on the side of the oil filter seat between the connecting port and the knob, and a clamping bolt hole is provided on the fixing portion.

[0010] Furthermore, the oil filter seat is made of metal material.

[0011] Furthermore, the machine filter is made of plastic.

[0012] Beneficial effects:

[0013] The engine lubrication system in the present application adopts a split structure design with a simple structure. Due to the split structure, when the engine is used for a long time, the oil filter screen will be filled with impurities. The user can directly replace the filter screen part without replacing the entire oil filter, which causes waste of cost and materials. The oil filter seat part can also be recycled, and the oil filter seat is made of metal material to avoid deformation and oil leakage under high temperature. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0019] Example

[0020] An engine lubrication system, such as Figures 1 to 3 As shown, it includes an oil filter body 1 and an oil filter seat 2. The oil filter body 1 is hollow, and a connecting part is provided at one end of the oil filter body 1, and a connecting port matched with the connecting part is provided at one end of the oil filter seat 2. A circle of sealing grooves 5 are provided on the outer ring of the connecting port, and a sealing ring is sleeved on the sealing groove 5. A groove 9 is provided inside the connecting port, and a convex strip 10 matched with the groove 9 is provided outside the connecting part, and an internal control barb is provided inside the oil filter seat 2 (not shown in the figure).

[0021] Specifically, the engine lubrication system in this embodiment adopts a structure in which the oil filter body 1 and the oil filter seat 2 are separated. In order to ensure the sealing of the connection between the oil filter body 1 and the oil filter seat 2, a matching connection part and a connection port are provided, and a groove 9 is provided in the connection part, and a convex strip 10 is provided in the connection port, so that they can cooperate during installation to ensure that the oil filter body 1 and the oil filter seat 2 do not slide relative to each other. In addition, because the oil filter seat 2 is provided with internal control barbs, the oil filter body 1 is limited to avoid accidental pulling out or falling off. After the oil filter body 1 and the oil filter seat 2 are combined, in order to ensure the sealing, a sealing ring is set on the outer ring of the oil filter seat 2 through the sealing groove 5 to avoid oil leakage.

[0022] Preferably, the filter body 1 is provided with a filter screen 3 and an oil outlet 4. Because the filter screen 3 is a high-density mesh material structure, and the pores are smaller than the diameter of the impurity particles inside the oil, when the oil with impurity particles passes through, the impurities are blocked outside by the filter screen 3, so that clean oil is obtained, and finally enters the main oil channel of the engine through the oil outlet 4.

[0023] Preferably, a knob 7 is provided at the other end of the oil filter seat 2. The knob 7 facilitates the user to perform operations such as disassembly and installation.

[0024] Preferably, a fixing portion 6 is provided on the side of the oil filter seat 2 between the connection port and the knob 7, and a clamping bolt hole 8 is provided on the fixing portion 6. The clamping bolt hole 8 is used to insert a clamping bolt to fix the entire system.

[0025] Preferably, the oil filter seat 2 is made of metal material, specifically aluminum material, to ensure that the oil filter seat 2 will not deform with the increase of oil temperature, thereby preventing oil leakage. The oil filter body 1 is made of plastic for easy production.

[0026] Although the embodiments of the present invention are described in the specification, these embodiments are only for reference and should not limit the protection scope of the present invention. Various omissions, substitutions and changes within the scope of the present invention should be included in the protection scope of the present invention.
