Description

Technical Field

[0001] This utility model relates to the technical field of pipeline connection devices, and in particular to a quick connection device for the inlet and outlet of a fluid electric pump. Background Technology

[0002] Currently, some traditional electric pumps on the market rely on flange connections for their inlet and outlet connections. This connection method uses bolts and nuts to fasten the flanges to the matching flanges at the ends of external pipes, and a gasket is installed between the two flange faces to achieve a seal.

[0003] However, in practical applications, there is a need to use hoses for connection. Traditional electric pumps are only equipped with flange connection mechanisms, but they cannot achieve quick connection, especially for hoses. Therefore, this needs to be addressed. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a quick docking device for the inlet and outlet of a fluid electric pump.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A quick docking device for the inlet and outlet of a fluid electric pump includes a coupling connector. The coupling connector is installed in the middle of the coupling pipe via an extension pipe. The coupling pipe is connected to the output port of the pump body. A sleeve for connecting a flexible hose is provided in the middle of one side of the coupling connector. A pair of extrusion blocks are slidably installed on both sides away from the sleeve. An inclined groove is provided on the side wall of the extrusion block. The upper part of the inclined groove is in extrusion contact with the extrusion rod provided at the bottom of the pressure plate. The pressure plate is driven to rise and fall by adjusting bolts.

[0006] In addition, a preferred structure is that one end of the connecting pipe is provided with a flange to realize the basic pipeline connection function, and a hand valve is installed in the middle of the connecting pipe.

[0007] Furthermore, in a preferred configuration, an extension pipe is obliquely connected to one side of the middle portion of the connecting pipe, and a second hand valve is installed in the middle of the extension pipe.

[0008] In addition, a preferred structure is that a connector is installed on one side of the extension tube, a connection interface is provided in the middle of the connector for screwing the sleeve, and an expansion connector assembly is provided on the outside of the connector.

[0009] In addition, a preferred structure is that a plurality of sliding grooves are provided on one side of the outer wall of the connector, and the sliding grooves are matched and connected with the protrusions provided on the outer wall of the extrusion block, so that the extrusion block can achieve lateral displacement through the sliding grooves.

[0010] In addition, a preferred structure is that an adjusting bolt is rotatably installed at the middle of the upper end of the connector, a pressure plate is screwed to the middle of the adjusting bolt, and limiting rods are provided on both sides of the bottom of the pressure plate and extend into the limiting holes opened in the upper wall of the connector.

[0011] Furthermore, in a preferred configuration, when the extrusion rod is in a vertical position, the bottom end of the extrusion rod presses against the inner wall of the inclined groove and generates a radial driving force to drive the extrusion block to move.

[0012] The beneficial effects of this utility model are as follows: In this invention, adjusting the bolt drives the pressure plate downward, which in turn moves a pair of extrusion blocks and extrudes and seals the hose fitted onto the sleeve, thereby achieving rapid connection and sealing of the hose and effectively improving the efficiency of pipe connection.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figure 1-4 A quick docking device for the inlet and outlet of a fluid electric pump includes a docking connector 42, which is installed in the middle of the docking pipe 4 via an extension pipe 41. The docking pipe 4 can be docked with the output port 2 or input port 3 of the pump body 1 via a flange and fasteners. Among them, a sleeve 9 for connecting a flexible hose is provided in the middle of one side of the connector 42, and a pair of extrusion blocks 6 are slidably installed on both sides away from the sleeve 9. The side wall of the extrusion block 6 is provided with a groove 13, and the upper part of the groove 13 is in contact with the extrusion rod 81 provided at the bottom of the pressure plate 8. The pressure plate 8 is driven to rise and fall by adjusting bolt 82. One end of the connecting pipe 4 is equipped with a flange to realize the basic pipeline connection function, and a hand valve 5 is installed in the middle of the connecting pipe 4. The fluid flow state inside the connecting pipe 4 is controlled by opening and closing the hand valve 5. An extension pipe 41 is installed obliquely on one side of the middle of the connecting pipe 4. A hand valve 10 is installed in the middle of the extension pipe 41. The fluid flow state inside the extension pipe 41 is controlled by opening and closing the hand valve 10.

[0017] One side of the extension tube 41 is connected to a connector 42, and a connector 12 is provided in the middle of the connector 42 to screw the sleeve 9. An expansion connector group 7 is provided on the outside of the connector 42, wherein the outer diameter of the sleeve 9 is adapted to a hose with a pipe opening size of DN20. The expansion connector assembly 7 includes a plate and multiple auxiliary sleeves. The outer diameter of each auxiliary sleeve is the same as that of standard hoses with diameters of DN15 and DN25, thus meeting the needs of some mainstream hose interfaces on the market. Each auxiliary sleeve is screwed onto the plate and can be disassembled and replaced by threads.

[0018] Multiple grooves 14 are provided on one side of the outer wall of the connector 42. The grooves 14 are matched and connected with the protrusions provided on the outer wall of the extrusion block 6. The extrusion block 6 achieves lateral displacement through the grooves 14.

[0019] An adjusting bolt 82 is rotatably installed at the upper middle part of the connector 42. A pressure plate 8 is screwed to the middle of the adjusting bolt 82. Limiting rods 15 are provided on both sides of the bottom of the pressure plate 8 and extend into the limiting holes 11 opened on the upper wall of the connector 12.

[0020] When the extrusion rod 81 is in the vertical position, the bottom end of the extrusion rod 81 is pressed against the inner wall of the inclined groove 13 and generates a radial driving force to drive the extrusion block 6 to move.

[0021] In this embodiment, the hose is fitted onto the sleeve 9, and the adjusting bolt 82 is rotated to drive the pressure plate 8 downward. The downward movement of the pressure plate 8 causes the extrusion rod 81 to match and engage with the inclined groove 13 of the extrusion block 6. Through the inclined groove structure of the inclined groove 13, the vertical displacement of the extrusion rod 81 is converted into the lateral displacement of the extrusion block 6, thereby driving the extrusion block 6 to move inward and extrude pressure on the outer wall of the hose fitted onto the sleeve 9 until the seal is deformed and fits against the outer wall of the hose to form a seal.

[0022] In addition, when conveying hoses through extension pipe 41, it is necessary to close hand valve 5 in the middle of the connecting pipe 4 and open hand valve 10. Conversely, when conveying and connecting normal flange fittings through connecting pipe 4, it is necessary to close hand valve 10 and open hand valve 5.

[0023] Alternatively, it can still be removed from the interface 12 by rotating the loose sleeve 9.

[0024] In addition, it should be noted that the inner wall of the extrusion block 6 is provided with a rubber sealing block. By applying radial clamping force, the rubber block undergoes elastic deformation and forms a tight contact with the outer wall of the sleeve 9, thereby achieving fastening and sealing of the connection.

[0025] Meanwhile, when different sizes of sleeve 9 are replaced, the stroke of the extrusion block will change accordingly (the stroke decreases when the pipe diameter increases, and increases when the pipe diameter decreases), but due to the good elasticity and deformation adaptability of the rubber material, it can still maintain effective contact pressure and sealing performance.

[0026] Of particular note is pump body 1, which is the electric pump body.

[0027] Therefore, compared to traditional electric pumps that can only achieve flange connections, this mechanism effectively improves docking efficiency by setting up a quick docking device specifically for connecting hoses in the connecting pipe.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
