A mounting shell is fixedly connected to the output end of the electric pump body. An inner mounting shell is coaxially and fixedly connected inside the mounting shell. Three sliding grooves are arranged on the inner wall of the mounting shell in a circumferential array. Clamping rods are slidably connected in the sliding grooves. A clamping block is fixedly connected to the end of the clamping rod away from the mounting shell. Multiple clamping rods move synchronously through a clamping assembly. A regulating box is fixedly connected to the side end of the mounting shell. A regulating assembly for driving the clamping assembly to work is arranged in the regulating box.

One ends of the plurality of variable-diameter joints close to the output end have the same outer diameter, and the other ends have different outer diameters. When the runner is rotated, the plurality of variable-diameter joints are sequentially and respectively attached to the output end;

[0010] Furthermore, a sealing ring is arranged at the junction of the output end and the reducing joint.

[0011] Furthermore, one end of the sealing ring is fixedly connected with an annular convex block, and an annular groove for the annular convex block to be embedded is opened at one end of the output end close to the reducing joint.

[0012] Furthermore, the clamping mechanism includes an upper clamping plate and a lower clamping plate hinged at the end.

Such a setting can quickly adapt to external pipelines with different diameters by rotating the runner, improving the applicability and flexibility of the pump. At the same time, through the locking assembly and the clamping mechanism, the stability and safety of the connection are ensured. It effectively improves the problem that the clamping block cannot fully fit the surface of the pipeline when the electric pump adapts to pipelines of different sizes, affecting the sealing effect.

Specific implementation manner

[0021] The technical solutions of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0022] An embodiment of the present application discloses an efficient electric pump. Refer to Figures 1 to 3 , an efficient electric pump includes an electric pump 1 body and an output end 2 provided on the electric pump 1 body. A mounting shaft 3 is horizontally and fixedly connected to one side of the electric pump 1 body close to the output end 2. A runner 31 is rotatably mounted on the mounting shaft 3. A plurality of mounting sleeves 32 arranged along its width direction are fixedly connected to the inner peripheral wall of the runner 31. A reducing joint 33 is arranged in the mounting sleeve 32. One ends of the plurality of reducing joints 33 close to the output end 2 have the same outer diameter, and the other ends have different outer diameters. When the runner 31 is rotated, the plurality of reducing joints 33 are sequentially and respectively attached to the output end 2;

[0023] Convex rings 21 are provided at one ends of the output end 2 and the reducing joint 33 facing each other. A locking assembly for locking the output end 2 and one of the reducing joints 33 is provided between the two opposing convex rings 21. A clamping mechanism for fixing an external pipe is provided at one end of the reducing joint 33 facing away from the output end 2.

[0024] When connecting an external pipe, first find a reducing joint 33 suitable for the current diameter of the external pipe, then rotate the runner 31 to make the selected reducing joint 33 fit with the output end 2, then use the locking assembly to lock the output end 2 and the reducing joint 33, and finally use the clamping mechanism to fix the reducing joint 33 and the external pipe. This setting can quickly adapt to external pipes of different diameters by rotating the runner 31, improving the applicability and flexibility of the pump. At the same time, through the locking assembly and the clamping mechanism, the stability and safety of the connection are ensured. Effectively improves the problem that the clamping block cannot fully fit the surface of the pipe when the electric pump 1 adapts to pipes of different sizes, affecting the sealing effect.

[0025] Specifically, refer to Figures 1 to 3, the locking assembly includes an inner screw cylinder 22 rotatably sleeved on one of the convex rings 21, and the inner screw cylinder 22 is threadedly sleeved on the outer periphery of the other opposite convex ring 21. The rotation of the inner screw cylinder 22 realizes the locking of the output end 2 and the reduced-diameter joint 33, ensuring the stability of the connection.

[0026] And referring to Figures 1 to 3 , a sealing ring 4 is provided at the junction of the output end 2 and the reduced-diameter joint 33, further improving the sealing performance of the connection part.

[0027] And referring to Figures 1 to 3 , one end of the sealing ring 4 is fixedly connected with an annular convex block 41, and an annular groove 23 for the annular convex block 41 to be embedded is opened at one end of the output end 2 close to the reduced-diameter joint 33. When the reduced-diameter joint 33 and the output end 2 are locked by the inner screw cylinder 22, the annular convex block 41 will be squeezed into the annular groove 23. Due to the elasticity of the sealing ring 4, the annular convex block 41 can tightly fill the annular groove 23, thus forming an additional sealing barrier between the two connecting components and increasing the stability of the connection part at the same time.

[0028] Furthermore, referring to Figure 1 , the clamping mechanism includes an upper clamping plate 5 and a lower clamping plate 51 with hinged ends. Both the upper clamping plate 5 and the lower clamping plate 51 are arc-shaped and form a ring after enclosing. Convex blocks 52 are provided at the free ends of the upper clamping plate 5 and the lower clamping plate 51, and a fixing component for fixing the two is arranged between the two convex blocks 52. The upper and lower clamping plates 51 can be opened and closed through the hinged design, which is convenient for installing and disassembling external pipelines. The arc-shaped design enables the clamping plates to closely fit the outer surface of the circular pipeline. When the upper and lower clamping plates 51 are closed, they form a complete ring structure, which can evenly distribute the pressure and avoid causing local damage to the pipeline. [[ID=X]] [[ID=Y]]

[0029] At the same time, referring to Figure 1 , the fixing component includes a fixing bolt 6 and a fixing nut 61. A fixing hole adapted to the insertion of the fixing bolt 6 is penetrated through the convex block 52, which can provide adjustable clamping force to adapt to pipelines of different materials and thicknesses. At the same time, the operation is simple and it is convenient for installation and disassembly.

[0030] In addition, referring to Figure 1 , a handle 311 is fixedly connected to the runner 31 along its width direction, further improving the convenience and efficiency of operation.

[0031] The implementation principle of an efficient electric pump 1 in the embodiment of the present application is as follows:

[0032] When connecting an external pipe, first find a reducing joint 33 suitable for the diameter of the current external pipe. Then rotate the rotating wheel 31 to make the selected reducing joint 33 fit with the output end 2. Next, use the locking component to lock the output end 2 and the reducing joint 33. Finally, use the clamping mechanism to fix the reducing joint 33 and the external pipe. Such a setting can quickly adapt to external pipes of different diameters by rotating the rotating wheel 31, improving the applicability and flexibility of the pump. At the same time, through the locking component and the clamping mechanism, the stability and safety of the connection are ensured. It effectively improves the problem that the clamping block cannot fully fit the surface of the pipe when the electric pump 1 adapts to pipes of different sizes, affecting the sealing effect.
