[0033] Please refer to the attached Figure 1-5In one embodiment of the present invention, an electronic water pump that is easy to connect to a pipeline includes an electronic water pump body 40, one end of the electronic water pump body 40 is convexly provided with a tube body 410, and the tube body 410 is used to connect to an external water pipe 50, and also includes a connecting sleeve 30, a connecting assembly 10 and a plurality of pressure plate assemblies 20 for abutting against the tube body 410 and the external water pipe 50. First of all, it should be noted that, unlike the electronic water pump in the prior art, when it is connected to the external pipeline, it needs to be connected to the external pipeline through a strapping belt, which causes the problem of slow connection efficiency, and after the connection, the sealing performance is poor, which easily leads to water leakage. The present application solves the above-mentioned defects in the prior art by providing an electronic water pump that is easy to connect to the pipeline. The details are as follows:

[0034] The connecting sleeve 30 is sleeved at the connection between the tube body 410 and the external water pipe 50; the connecting assembly 10 is connected to the inner side of the connecting sleeve 30, and the connecting assembly 10 is provided with a plurality of radial channels arranged at intervals along the circumference of the connecting sleeve 30, and each of the radial channels is provided with a pressure plate assembly 20, and the pressure plate assembly 20 is connected to the radial channel and is movably arranged radially along the connecting sleeve 30.

[0035] Specifically, the electronic water pump for easy pipe connection in the present application includes an electronic water pump body 40, and a pipe body 410 is convexly formed at one end of the electronic water pump body 40, and the pipe body 410 is used to connect with an external water pipe. The connection method of the joint 510 can be used to make the connection more stable and have good sealing, and a sealing ring 520 is added to further improve the sealing; and it also includes a connecting sleeve 30, a connecting assembly 10 and a plurality of pressure plate assemblies 20, the connecting sleeve 30 is used for the installation of the connecting assembly 10, and at the same time, the connection between the external water pipe and the pipe body 410 is enclosed to improve the sealing, so it is sleeved on the connection between the pipe body 410 and the external water pipe 50; the connecting assembly 10 is used for the installation of the pressure plate assembly 20, which is connected to the inner side of the connecting sleeve 30, and the pressure plate assembly 20 is used to tighten the connection between the external water pipe 50 and the pipe body 410, so that it is different from the binding belt and its connection is more stable and convenient.

[0036] Among them, the connecting assembly 10 is provided with a plurality of radial channels arranged at intervals along the circumference of the connecting sleeve 30, and the radial channels are used for the installation and connection of the pressure plate assembly 20, so that the pressure plate assembly 20 is movably connected in the radial direction of the connecting sleeve 30 in the radial channel, so that when a reinforced connection is required, the pressure plate assembly 20 is moved radially inward to abut against the pipe body 410 and the external water pipe 50, so as to achieve the purpose of reinforcing the connection and provide a better fixing effect.

[0037] As a preferred embodiment of the present invention, the connecting assembly 10 includes an outer cylinder 111, an inner cylinder 112 and a plurality of connecting plates 113 arranged at intervals along the circumference of the outer cylinder 111. The outer cylinder 111 and the inner cylinder 112 are connected by the connecting plates 113 to form a swivel 110. The inner cylinder 112 is provided with the radial channel, and the connecting plate 113 is provided with a slide groove 1131. One end of the pressure plate assembly 20 is slidably connected to the slide groove 1131 so as to be movably arranged in the radial channel.

[0038] It should be noted that the outer cylinder 111 is used to connect to the inner side of the connecting sleeve 30, and the inner cylinder 112 is used for the installation of the pressure plate assembly 20. Therefore, the radial channel is opened on the inner cylinder 112, so that the outer cylinder 111 and the inner cylinder 112 are spaced to form a spacing space for the pressure plate assembly 20 to move radially. The two are connected and fixed by the connecting plate 113 to form an annular swivel 110 structure, which is more convenient for the pressure plate assembly 20 to slide, and at the same time has enough spacing space to facilitate one end of the pressure plate assembly 20 to be connected to the slide groove 1131 opened on the connecting plate 113, so as to cooperate with the slide groove 1131 when sliding.

[0039] As a preferred embodiment of the present invention, each of the pressure plate assemblies 20 includes an extrusion plate 210 and a movable plate 220, wherein the movable plate 220 is connected to one end of the extrusion plate 210 away from the tube body 410 and the external water pipe 50, and the movable plate 220 is protruded upward to form a sliding column 221, and the sliding column 221 is matched and connected in the slide groove 1131.

[0040] It should be noted that the extrusion plate 210 is used to squeeze the connection between the external water pipe 50 and the tube body 410, so as to strengthen the connection, and the movable plate 220 serves as a sliding body to drive the extrusion plate 210 to move, so it is connected to the end of the extrusion plate 210 away from the tube body 410 and the external water pipe 50, so as to be arranged close to the connecting plate 113. For the convenience of connection, a sliding column 221 is formed on the movable plate 220 to protrude upward, and the sliding column 221 is used to match and cooperate with the slide groove 1131 to play a role in limiting movement.

[0041] As a preferred embodiment of the present invention, the rotating ring 110 itself is rotatably arranged, and the connecting plate 113 and the sliding groove 1131 are both inclined.

[0042] It is worth mentioning that the rotating ring 110 is arranged to be rotatable in the circumferential direction so that when it rotates, it can drive the sliding column 221 on the movable block to move by rotating to cooperate with the sliding groove 1131, thereby driving the extrusion block to move radially. Considering that the rotating ring 110 rotates in the circumferential direction, the connecting plate 113 and the sliding groove 1131 are also arranged to be inclined, so as to push the sliding column 221 to slide and drive the extrusion plate 210 to slide when rotating.

[0043] As a preferred embodiment of the present invention, it also includes a tooth plate 120, a cover shell 310 and a screw rod 311, and a groove is opened on the connecting sleeve 30, wherein the tooth plate 120 is connected to the outer cylinder 111 and is located at the groove, the cover shell 310 is connected to the connecting sleeve 30 and is covered in the groove, the screw rod 311 itself is rotatably connected in the cover shell 310, and the screw rod 311 is meshed with the tooth plate 120.

[0044] It is worth noting that the tooth plate 120 is used to cooperate with the screw 311 to facilitate the technician to rotate the rotating ring 110. In order to facilitate the installation of the tooth plate 120, a groove is opened on the connecting sleeve 30, so that the tooth plate 120 can be connected to the outer cylinder 111 at the groove, and the cover 310 is covered in the groove to avoid the connection being exposed to the outside. The screw 311 is installed in the cover 310 and meshed with the tooth plate 120. In this way, by rotating the screw 311, the thread rotation transmits a rotational force to the tooth plate 120, thereby driving the entire rotating ring 110 to rotate, providing convenience for technicians.

[0045] Furthermore, the extrusion plate 210 is arranged in an arc shape at one end close to the tube body 410 and the external water pipe 50 .

[0046] It should be noted that since the end of the extrusion plate 210 close to the tube body 410 and the external water pipe 50 is used to abut against the external water pipe 50 and the tube body 410, and the pipeline is usually a round tube, it is set in an arc shape to match the round tube, so as to strengthen the connection more firmly.

[0047] Furthermore, one end of the extrusion plate 210 close to the tube body 410 and the external water pipe 50 is connected with a rubber block.

[0048] It should be understood that the provision of the rubber block can reduce the extrusion damage to the tube body 410 and the external water pipe 50, and play a protective role. In addition, the rubber also has a certain waterproof performance and improves the sealing performance.

[0049] Furthermore, the number of the pressure plate assemblies 20 is six, and the six pressure plate assemblies 20 are arranged at intervals along the circumference of the connecting sleeve 30 .

[0050] It should be noted that the number of the pressure plate assemblies 20 can be determined according to the diameter of the inner cylinder 112. In the present application as a preferred embodiment, the number of the pressure plate assemblies 20 is six, and those skilled in the art can set it according to actual needs.

[0051] Furthermore, a knob is included, and the knob is connected to one end of the screw rod 311 .

[0052] It can be understood that the knob can make it easier for technicians to turn the screw 311, thereby improving operational convenience.

[0053] To facilitate understanding by those skilled in the art, the operation flow of this application is briefly described as follows:

[0054] In actual application, the external water pipe 50 is moved to the inside of the connecting sleeve 30. At this time, the joint 510 of the external water pipe 50 (which can be pre-inserted on the external water pipe 50) is inserted into the inside of the tube body 410, and the sealing ring 520 contacts the tube body 410. Then the screw 311 is rotated, and the meshing transmission between the screw 311 and the tooth plate 120 drives the entire rotating ring 110 to rotate. During the rotation of the entire rotating ring 110, the middle connecting plate 113 rotates synchronously, so that the slide groove 1131 squeezes the slide column 221 to drive the movable plate 220 to move, and the extrusion plate 210 connected to the movable plate 220 moves synchronously in the radial direction toward the middle, so that the extrusion plate 210 is fixed to the external water pipe 50 and the tube body 410, and there is no need for the staff to fix it with a binding belt, thereby improving the efficiency of fixing the external water pipe 50 and reducing the labor intensity of the staff to fix the external water pipe 50.

[0055] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
