[0002] Gasoline engine water pump is a centrifugal pump, which consists of a water pump and a bracket. It has low cost, light weight, easy maintenance, low manufacturing cost and low noise. The common gasoline engine water pump is a centrifugal pump. The working principle of the centrifugal pump is that when the pump is full of water, the engine drives the impeller to rotate, thereby generating centrifugal force. The water in the impeller groove is thrown to the periphery and flows into the pump casing under the action of centrifugal force, so the pressure at the center of the impeller is reduced. This pressure is lower than the pressure in the water inlet pipe. Under the action of this pressure difference, water flows from the suction pool into the impeller. In this way, the water pump can continuously absorb water and continuously supply water.

[0003] A gasoline engine water pump generally includes a bracket, a gasoline engine and a water pump, wherein a plate for connection is installed at the ends of the gasoline engine and the water pump. The cross-section of the plate is generally quadrilateral, and through holes are opened at the four corners of the plate. When connecting the gasoline engine and the water pump, the bolts are inserted into the through holes of the plate on the gasoline engine and the water pump, and the connection of the gasoline engine and the water pump is completed through the threaded cooperation of the bolts and nuts. This connection method is more troublesome to operate when connecting the gasoline engine and the water pump, and it is necessary to operate multiple pairs of bolts and nuts one by one.

The elastic member includes a first spring 13 and a limit block 14. The limit block 14 is movably arranged in the groove of the moving block 12. One end of the limit block 14 is an inclined surface facing the gasoline engine 3. Since one end of the limit block 14 is in an inclined structure, the inclined surface of the limit block 14 can move into the groove of the moving block 12 when it is squeezed from the outside, which is convenient for limiting.
