[0003] The water pump housing commonly found on the market is fixed and connected by structures such as bolts, but components such as screws may become stuck due to rust, and forced disassembly may damage the nuts, making disassembly difficult. Summary of the invention

[0004] The purpose of the utility model is to provide a new water pump housing which is easy to operate in view of the above problems existing in the prior art.

[0005] The purpose of the utility model can be achieved through the following technical solutions: a new type of water pump housing, characterized in that it includes a water pump body composed of a left housing and a right housing, the water pump body is provided with a plurality of mounting holes evenly distributed in an annular manner, the mounting holes are provided with locking pieces, the locking piece is provided with a central axis, the central axis is provided with a plurality of spiral portions evenly distributed in an annular manner, the mounting holes are provided with a clamping portion engaged with the locking piece, the locking piece is provided with a U-shaped rod, a cover bolt is provided on the left housing, the top end of the U-shaped rod is provided on the cover bolt 1, and the locking piece, the clamping portion and the cover bolt are all provided with insertion holes for the U-shaped rod to be clamped.

[0006] In the above-mentioned novel water pump housing, a plurality of protrusions are evenly distributed in an annular shape on the right housing, and a limit block is provided on the protrusion, and an open groove is provided on the limit block, and the ends of the U-shaped rods are all snap-fitted into the open groove.

[0007] In the above-mentioned novel water pump housing, guide parts are provided on both sides of the limit block, and guide grooves are provided on the protruding part.

[0008] In the above-mentioned novel water pump housing, limiting strips are provided on both sides of the side walls of the opening groove, and a clamping ring is provided on the U-shaped rod.

[0009] Compared with the prior art, the water pump housing of the present invention installs the water pump body through the spiral part on the locking piece, and then realizes the U-shaped rod through the cover bolt and the limit block to complete the locking. When disassembling, only the limit block is needed to remove the U-shaped rod, and then the disassembly can be completed by removing the locking piece, thereby reducing the problem of parts getting stuck due to rust.
