Description

Technical Field

[0001] The utility model relates to the field of water pump equipment, in particular to a quick docking structure between a water pump volute and a base. Background Art

[0002] In the field of water pump equipment, the pump volute and base are two important components of the pump. The accuracy of their connection directly affects the performance and efficiency of the pump. The pump volute and base are connected together with bolts. This connection method is simple, but the assembly process requires special attention to the coaxiality of the through-hole and the threaded hole. The existing water pump volute and base assembly process relies on the workers' experience to ensure the coaxiality of the through-hole and the threaded hole. This not only reduces the consistency of the assembly and increases the assembly time, but also makes it difficult to ensure the reliability of the assembly. Utility Model Content

[0003] The utility model makes structural innovation on the water pump volute and base, adds a positioning auxiliary function, plays a limiting role, can effectively reduce the misalignment phenomenon, and ensures the accuracy of assembly.

[0004] Firstly, the utility model adds a groove structure to the bottom of the water pump volute.

[0005] Secondly, a new structural design was carried out on the base. The base has a layout of six columns and three through holes. A raised structure was added to the outside of one of the columns with a through hole. The groove structure on the water pump volute and the raised structure on the base are distributed on a circle of the same diameter. The groove structure at the bottom of the water pump volute and the raised structure on the base have exactly the same geometric profile, which can achieve complete overlap between the concave profile of the groove structure and the convex profile of the raised structure. They can be interlocked during the assembly process to achieve a limiting effect.

[0006] Compared with the existing technology, the beneficial effects of this technical solution are as follows:

[0007] 1. Improve assembly efficiency: The utility model realizes the rapid positioning and connection of the water pump volute and the base by adding a groove structure on the water pump volute and a protruding structure on the base, which greatly reduces the alignment time of the through hole and the threaded hole during the assembly process and improves the assembly efficiency.

[0008] 2. Reduce assembly difficulty: The groove structure and protrusion structure design of the utility model make it possible to achieve the limiting effect during the assembly process by simply inserting the protrusion structure of the base into the groove structure of the water pump volute, avoiding the problem of paying special attention to the correspondence between the through hole and the threaded hole in the traditional method, reducing the assembly difficulty and thus reducing the possibility of errors during the assembly process.

[0009] 3. Improve water pump performance: Due to the groove structure and convex structure design of the utility model, the connection between the water pump volute and the base is more stable, thereby improving the performance and efficiency of the water pump. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The present invention will be described in detail below with reference to the accompanying drawings.

[0016] The utility model makes structural innovations for the water pump volute 1 and the base 4, adds a positioning auxiliary function, plays a limiting role, can effectively reduce the misalignment phenomenon, and ensure the accuracy of assembly.

[0017] Firstly, the present invention adds a groove structure 3 to the bottom of the water pump volute 1 in the structure.

[0018] Secondly, the new structural design on the base 4 is a layout of six columns 6 and three through holes. A protruding structure 7 is added to the outside of one of the columns 6 with a through hole. The groove structure 3 on the water pump volute 1 and the protruding structure 7 on the base 1 are distributed on a circle of the same diameter. The groove structure 3 at the bottom of the water pump volute 1 and the protruding structure 7 on the base 4 have exactly the same geometric profile, which can achieve complete overlap between the concave profile of the groove structure 3 and the convex profile of the protruding structure 7, and they can be interlocked during the assembly process to achieve a limiting effect.

[0019] As attached Figure 1 It can be clearly seen that there are three threaded holes 2 evenly distributed on the bottom surface of the water pump volute 1. A groove structure is set on the outside of one of the bolt holes 2. During the installation process, the position of the groove structure 3 can be directly determined.

[0020] By attaching Figure 3 It can be seen that the base 4 uses six columns 6, three of which have through holes 5, and a protrusion 7 is provided on the outside of one of the through holes 5. The groove structure 3 on the water pump volute 1 and the protrusion 7 on the base 4 are distributed on a circle with the same diameter.

[0021] During the installation process, the raised structure 7 of the base 4 is inserted into the groove structure 3 of the water pump volute 1 to achieve a limiting effect, thereby ensuring the coaxiality of the through hole 5 and the threaded hole 2, and then the water pump volute 1 and the base 4 are fastened together by long bolts.
