[0002] When connecting a water pump to a generator, a bolt hole is usually drilled in the water pump casing, and bolts are used to fasten it to the generator bracket. However, due to limited operating space, the bolt hole installation method requires workers to reach into the gap between the water pump and the generator to operate, which is quite inconvenient. Utility Model Content

[0003] To address the shortcomings of the prior art, this utility model provides a water pump housing that is easy to mount on an engine bracket. This utility model adds a boss so that the bolt holes are higher than the pump housing, making it easy to operate, convenient to use, and low in cost.

[0004] To achieve the above technical objectives, the present invention adopts the following technical solution: a water pump housing that is easy to mount on an engine bracket, comprising a pump housing body, wherein the edge of the pump housing body is provided with a boss;

[0005] The boss includes a boss body, and the bottom end of the boss body is provided with an outwardly flared edge, which is used to fix and connect the pump housing body.

[0006] The top of the boss body is provided with bolt holes and stepped holes. The bolt holes and stepped holes are coaxial. The diameter of the bolt holes is smaller than the diameter of the stepped holes. The bolt holes are used to fasten the engine bracket with bolts, and the stepped holes are used to embed and accommodate the steps of the engine bracket.

[0007] The boss body has a cylindrical structure, the outer expansion edge has a cylindrical structure, and the boss body and the outer expansion edge are provided with fixing holes for bolts to be fastened to the pump housing body.

[0008] The outer expansion edge is welded and fixed to the pump casing body.

[0009] The stepped hole is cylindrical, and the step is cylindrical.

[0010] In summary, this utility model achieves the following technical effects:

[0011] This invention features a boss on the pump casing, which makes the bolt holes higher, facilitating the fixing of the bracket and making it easier for workers to operate. Attached Figure Description

[0020] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0021] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0023] Example:

[0024] Figure 1 It is a water pump housing that is easy to mount on an engine bracket, including a pump housing body 1, and the edge of the pump housing body 1 is provided with a boss 2.

[0025] This utility model provides a boss 2 on the pump casing body, which facilitates the installation of the generator bracket 3 and increases stability.

[0026] Figure 2 This is a diagram of a boss. Figure 3 yes Figure 2 A cross-sectional schematic diagram, Figure 4 This is a schematic diagram of the generator support. Figure 5 This is a schematic diagram of the generator bracket connection boss. The boss 2 includes a boss body 201. The bottom end of the boss body 201 is provided with an outwardly expanding edge 202. The outwardly expanding edge 202 is used to fix and connect the pump housing body 1.

[0027] The boss body 201 adopts a cylindrical structure, and the outer expansion edge 202 adopts a cylindrical structure, which facilitates processing.

[0028] The outer flank 202 of this utility model can be fixed in two ways: First, the boss body 201 and the outer flank 202 are provided with fixing holes 205 for bolts to be fastened to the pump housing body 1.
