The bolts and nuts are exposed to the air for a long time and are easily rusted by external influences, making it difficult to remove the top cover and inconvenient to repair the inside of the housing. Therefore, it is of great significance to design a corrosion-resistant water pump housing. Summary of the invention

[0004] The purpose of the utility model is to provide a corrosion-resistant water pump housing in view of the above problems existing in the prior art.

[0006] In the above-mentioned corrosion-resistant water pump housing, a movable groove is opened on the inner wall of the mounting plate, a pressure plate is slidably arranged in the movable groove, and the pressure plate is fixedly connected to the surface of the connecting rod, and a spring is arranged between the pressure plate and the movable groove.

[0007] In the above-mentioned corrosion-resistant water pump housing, a rotating block is fixedly connected to the top end of the connecting rod.

[0008] In the above-mentioned corrosion-resistant water pump casing, the surfaces of the water pump casing, top cover, connecting plate and mounting plate are coated with an anti-corrosion coating.

[0009] Compared with the prior art, the corrosion-resistant water pump casing of the present invention connects the water pump casing and the top cover by means of a positioning block and a snap-in groove, making the connection and disassembly of the top cover and the water pump casing more convenient, facilitating the maintenance of the water pump and improving the efficiency of the water pump maintenance work.

[0016] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0017] like Figure 1 , 2 As shown in Figures 3, 4 and 5, the corrosion-resistant water pump housing comprises a water pump housing 1, a top cover 2 is arranged on the water pump housing 1, a connecting plate 3 is fixedly arranged on the water pump housing 1, a mounting plate 4 is fixedly arranged on the top cover 2, a plurality of connecting rods 5 are movably arranged on the mounting plate 4, a positioning block 6 is fixedly connected to the bottom end of the connecting rod 5, a plurality of connecting grooves 7 corresponding to the positioning block 6 are provided on the connecting plate 3, a rotating groove 8 and a clamping groove 9 are provided in the connecting groove 7, the water pump housing 1 and the top cover 2 are clamped in the clamping groove 9 through the positioning block 6, so as to complete the connection between the top cover 2 and the water pump housing 1, and the rotating groove 8 is a circular groove, so that the positioning block 6 can rotate in the rotating groove 8.

[0018] Preferably, a movable groove 10 is opened on the inner wall of the mounting plate 4, and a pressure plate 11 is slidably arranged in the movable groove 10, and the pressure plate 11 is fixedly connected to the surface of the connecting rod 5, and a spring 12 is arranged between the pressure plate 11 and the movable groove 10. When the water pump housing 1 is connected to the top cover 2, the connecting rod 5 is pressed to make the positioning block 6 enter the rotating groove 8 through the connecting groove 7, and then the connecting rod 5 is rotated to make the positioning block 6 enter the clamping groove 9. When the connecting rod 5 is not subjected to external force, the force of the spring 12 squeezes the pressure plate 11, and then drives the positioning block 6 to be clamped in the clamping groove 9 through the connecting rod 5, thereby completing the connection between the water pump housing 1 and the top cover 2.

[0019] Preferably, a rotating block 13 is fixedly connected to the top end of the connecting rod 5 , and the rotating block 13 is used to control the rotation of the connecting rod 5 and the positioning block 6 .
