[0077] In order to better illustrate the technical effects of the present invention, the present invention provides the following specific embodiments to illustrate the above technical process:

[0078] Example 1: An integrated lubrication pump cover, such as Figures 1 to 3 As shown, it includes a box cover 1, a cover plate 2, and an oil tank 3. The oil tank 3 has a built-in transmission shaft 10, a liquid level switch 5, a pressure switch 7, and a gear pump head 12. When the motor 6 is powered on, it outputs the lubricating oil stored in the oil tank to the lubrication point of the equipment.

[0079] At the same time, the built-in liquid level switch 5 will constantly monitor the oil level in the tank. When it is lower than the set point, it will send out an abnormal signal to remind you to refuel.

[0080] The built-in pressure switch 7 will always monitor the pressure during pump operation. When the pressure is lower than the set pressure value, it will send an abnormal signal to remind you to check the abnormality.

[0081] The advantages of using an integrated cover are low mold cost, low product unit price, simple assembly and easy maintenance.

[0082] The utility model integrates the power box 8 into the cover plate to form an integrated design, and integrates the motor 6, the detection device and the control system inside. The utility model has the advantages of simple assembly, few accessories, convenient maintenance and low cost.

[0083] The box cover 1 is installed on the top of the power box 8 through the positioning column 20. Three positioning columns 20 are installed on the inner wall of the power box 8, two of which are located around the two first notch portions 23, and the remaining positioning column 20 is located in the middle position of the inner front wall of the power box 8. The positioning column 20 is used to improve the assembly accuracy between the box cover 1 and the power box 8, and the assembly saves time and effort.

[0084] Cover plate 2 is mounted on top of fuel tank 3 via slots 29. Downward-extending outer and inner protrusions 27 and 28 are mounted on all four sides of the bottom of cover plate 2, forming slots 29. The four sides of the top opening of fuel tank 3 are inserted into slots 29. The diameter of slots 29 is larger than the thickness of the sidewalls of fuel tank 3, leaving a gap for movement and simplifying assembly. Fuel tank bolts are then passed through screw holes 32 in the cover plate and screwed onto connectors 31, securing cover plate 2 to fuel tank 3. The slots 29 and connectors 31 enhance the connection strength between cover plate 2 and fuel tank 3, simplifying subsequent maintenance and assembly.

[0085] The front side of the cover plate 2 is fixed to the fuel tank 3 by fuel tank bolts, and the power box 8 is arranged on the top rear side of the cover plate 2, and the power box 8 is wide at the bottom and narrow at the top. The gravity of the power box 8 is used to fix the rear side of the cover plate 2 to the fuel tank 3, which simplifies the connection structure between the cover plate 2 and the fuel tank 3 and ensures the connection strength; in addition, the first notch portion 23 of the power box 8 is adapted to the second notch portion 26 of the box cover 1, which facilitates the assembly of the box cover 1.

[0086] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present invention shall be covered by the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope of protection of the claims.
