Detailed Description

The following describes the present invention in further detail with reference to the accompanying drawings.

Example 1:

as shown in fig. 1-2, a novel water pump base comprises a base body 1, a water inlet cavity 2 is formed at the lower end of the base body 1, a groove 3 is formed in the upper end of the base body 1 and is inwards recessed, a through hole 13 is formed in the bottom of the groove 3, and the through hole 13 is communicated with the groove 3 and the water inlet cavity 2. Recess 3 mainly is that cooperation water pump shell 6 forms a chamber that holds that is used for installing the impeller, and a plurality of opening has been seted up to the lateral wall of the lower half of base main part 1, and the opening link up external world and intake chamber 2, for the water source provides water inlet 11 in getting into the water pump, is provided with a plurality of bosss 7 in intake chamber 2 inboards, and boss 7 is evenly distributed at 2 inner walls of intake chamber, and is circumference setting. Set up a plurality of connection positions 4 at the lateral wall of base main part 1, the position that connection position 4 set up corresponds the setting with the position of boss 7, and set up in boss 7, the shape of connection position 4 can be the connecting hole, the bottom setting of connecting hole is in boss 7, the lower side leaf of water pump shell 6 is seted up a plurality of and is used for and is connected 4 complex connecting holes of position, during the installation, insert water pump shell 6 with base main part 1 upper end in, later pass water pump shell 6's connecting hole with the one end of connecting piece 5 again, be connected with connection position 4, the connection of water pump shell 6 and base main part 1 has been accomplished promptly.

The technical scheme of the utility model be the structure to base main part 1 improves, through setting up boss 7 at intake antrum 2, set up connection position 4 on boss 7, replace the technical scheme of original go-between with this scheme, the benefit of design like this can avoid reducing the diameter of 1 upper end of base main part, just so can not influence the diameter of impeller, can guarantee the normal volume flow of water pump, because the go-between has been saved simultaneously, the installation of go-between has been saved, make base and water pump shell 6 be connected convenient and fast more, it is also convenient to dismantle, only need to twist off connecting piece 5 can.
