However, during the assembly process, we found that the connection between these two components lacks a positioning structure, and the sealing performance between them is low, affecting the overall service life. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a novel sealing connection structure for a booster pump, achieving the advantages of reliable positioning connection and efficient sealing.

[0004] The objective of this utility model can be achieved through the following technical solution: A novel sealing connection structure for a booster pump, comprising a pump body and a drive unit disposed on the pump body, characterized in that the pump body has a docking box, the bottom of the drive unit has an L-shaped docking plate, the end of the docking box has two positioning grooves extending inward therein, the L-shaped docking plate has two positioning protrusions extending into the corresponding positioning grooves, the shape of the positioning protrusions is the same as the groove shape of the positioning grooves, the end face of the docking box has an encircling sealing groove structure, and the sealing groove structure wraps the two positioning grooves within its inner circle, the sealing groove structure has a sealing device embedded therein, and two screw holes are also provided between the positioning grooves and the sealing groove structure, the L-shaped docking plate is fixed to the docking box by long rod screws.

[0005] In the aforementioned novel sealing connection structure for a booster pump, the positioning groove includes an extension groove protruding outward from its groove wall, and the longitudinal section of the extension groove is a trapezoidal structure.

[0006] In the above-mentioned novel sealing connection structure for a booster pump, the sealing groove structure has multiple sealing grooves around its inner ring wall, and the sealing device has multiple sealing protrusions embedded in the sealing grooves.

[0007] In the above-mentioned novel sealing connection structure for a booster pump, a sealing gasket is sandwiched between the top of the docking box and the bottom of the L-shaped docking plate.

[0008] Compared with existing technologies, this new sealing connection structure of the booster pump has the advantages of positioning and installation, stable connection, and improved sealing performance of the product after connection. Attached Figure Description

[0012] In the diagram, 1 is the pump body; 2 is the drive unit; 3 is the docking box; 4 is the L-shaped docking plate; 5 is the positioning groove; 6 is the positioning protrusion; 7 is the sealing groove structure; 8 is the screw hole; 9 is the extension groove; 10 is the sealing groove; 11 is the sealing gasket; and 12 is the long rod screw. Detailed Implementation

[0013] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0014] like Figure 1 , Figure 2 , Figure 3 As shown, this novel sealed connection structure for the booster pump includes a pump body 1 and a drive unit 2 mounted on the pump body 1. The pump body 1 has a docking box 3, and the bottom of the drive unit 2 has an L-shaped docking plate 4. The end of the docking box 3 has two positioning grooves 5 extending inward. The L-shaped docking plate 4 has two positioning protrusions 6 that extend into the corresponding positioning grooves 5. The shape of the positioning protrusions 6 is the same as the groove shape of the positioning grooves 5. The end face of the docking box 3 has an encircling sealing groove structure 7, which encloses the two positioning grooves 5 within its inner ring. A sealing device is embedded in the sealing groove structure 7. Two screw holes 8 are also provided between the positioning grooves 5 and the sealing groove structure 7. The L-shaped docking plate 4 is fixed to the docking box 3 by long screws 12, thereby fixing the pump body 1 and the drive unit 2 together.

[0015] To elaborate further, the positioning groove 5 includes an extension groove 9 that protrudes outward from its groove wall, and the longitudinal section of the extension groove 9 is a trapezoidal structure; similarly, the positioning convex plate 6 is in the same shape as the positioning groove 5, so the convex ridge with the trapezoidal structure on the positioning convex plate 6 engages with the extension groove 9 to improve the axial stability in the vertical direction.

[0016] To elaborate further, multiple sealing grooves 10 are formed around the inner wall of the sealing groove structure 7, and the sealing device has multiple sealing protrusions embedded in the sealing grooves 10, which realizes the stability of the sealing device installation, makes it less prone to displacement, and improves the sealing performance.

[0017] To improve sealing performance in all aspects, a sealing gasket 11 is sandwiched between the top of the docking box 3 and the bottom of the L-shaped docking plate 4.

[0018] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0019] Although this document frequently uses terms such as pump body 1, drive unit 2, docking box 3, L-shaped docking plate 4, positioning groove 5, positioning protrusion 6, sealing groove structure 7, screw hole 8, extension groove 9, sealing groove 10, sealing gasket 11, and long rod screw 12, the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
