Utility model content
The utility model is in view of the above-mentioned problems, provide a kind of cantilever pump connection structure.
The purpose of this utility model can be realized by following technical proposals: a kind of cantilever pump connection structure, including pump
Body, pump cover, motor, long threaded rod, nut and gasket；The rear side of the pump housing is pump cover installing port, and the outer wall on rear side of the pump housing is along week
To a circle flange projection is equipped with, the flange projection is arranged concentrically with pump cover installing port, is distributed along the circumference in flange projection more
A threaded hole；The front end of the pump cover is equipped with first boss seam allowance corresponding with pump cover installing port, the front end of pump cover and the pump housing
Rear side by the cooperation positioning of first boss seam allowance and pump cover installing port, the rear end of pump cover is equipped with groove seam allowance, the motor
Front side be equipped with integral type motor mounting plate, the motor mounting plate be equipped with second boss corresponding with groove seam allowance stops
Mouth and multiple holes corresponding with multiple threaded holes in flange projection, the rear end of the pump cover and the motor on front side of motor are installed
Plate is positioned by the cooperation of groove seam allowance and second boss seam allowance, the flange projection on rear side of the pump housing and the motor on front side of motor
Mounting plate is connected by long threaded rod, nut with gasket, and one end of the long threaded rod and the threaded hole of flange projection connect, long spiral shell
The Kong Houyu nut that the other end of column passes through on motor mounting plate is connected with gasket.
Compared with prior art, the utility model has the beneficial effects that having modified pump cover structure, the spiral shell at pump cover both ends is eliminated
Bolt connecting structure, pump cover both ends are positioned using seam allowance, are directly connected to the pump housing and motor by long threaded rod and nut, tighten long threaded rod
And pump cover is pressed between the pump housing and motor after nut；A set of long threaded rod, nut and pad are only needed when installation, maintenance, disassembly
Piece not only reduces the quantity of original fastener, has also unified the specification of fastener, staff is facilitated to install, improved work
Make efficiency；Due to reducing the radial dimension of pump cover, reduces the acknowledgment copy quantity of fastener, save pump cover material and fastening
The cost of part.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the prior art.
Fig. 2 is the overall structure diagram of the utility model.
Fig. 3 is the partial structural diagram of the utility model.
Part numbers are as follows in Fig. 1:

Specific embodiment
Specific embodiment of the present utility model is described in detail below in conjunction with attached drawing, becomes apparent from those skilled in the art
How ground understanding practices the utility model.Although describing the utility model in conjunction with its preferred embodiment, these
Embodiment only illustrates, rather than limits the scope of the utility model.
Referring to figs. 2 and 3, a kind of cantilever pump connection structure, including the pump housing 1, pump cover 2, motor 3, long threaded rod 4,5 and of nut
Gasket；The rear side of the pump housing 1 is pump cover installing port, and the outer wall of 1 rear side of the pump housing is circumferentially arranged with a circle flange projection 101, institute
It states flange projection 101 to be arranged concentrically with pump cover installing port, multiple threaded holes is distributed along the circumference in flange projection 101；The pump
The front end of lid 2 is equipped with first boss seam allowance 201 corresponding with pump cover installing port, and the front end of pump cover 2 and the rear side of the pump housing 1 pass through
