[0030] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0032] Furthermore, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments.

[0033] Example 1

[0034] Reference Figures 1-2 This embodiment provides a water pump pipe connector that is easy to install, including a connecting unit 100 and a connecting pipe 200. The connecting unit 100 is used to connect the water pipe 300 to the water pump interface.

[0035] The connecting unit 100 includes an adapter 101 and a fixing member 102 connected to the adapter 101. Both the adapter 101 and the fixing member 102 are rotating bodies. The adapter 101 is provided with a through first channel A, and the fixing member 102 is provided with a through second channel B.

[0036] The adapter 101 is provided with a connecting pipe 200 at the end away from the fixing member 102, and the connecting pipe 200 is integrally formed with the adapter 101.

[0037] Furthermore, the connecting pipe 200 is provided with an external thread 201, and the end of the connecting pipe 200 is provided with a tapered surface 202, on which the water pipe 300 is sleeved. That is, the water pipe 300 can be sleeved on the end of the tapered surface 202. The water pipe 300 is a flexible water pipe, and a fastening ring 400 is connected to the outside of the connecting pipe 200. The inner side of the fastening ring 400 is provided with an internal thread that mates with the external thread 201. The end of the water pipe 300 is located between the fastening ring 400 and the tapered surface 202. Therefore, when installing the water pipe 300, the fastening ring 400 is operated to connect with the connecting pipe 200 by thread, thereby securing the water pipe.

[0038] Preferably, a fastening ring 401 is provided on the inner side of the fastening ring 400 away from the adapter 101. The inner diameter of the fastening ring 401 is smaller than the outer diameter of the connecting pipe 200, but larger than the outer diameter of the small end of the tapered surface 202. Therefore, when the end of the water pipe 300 is fitted onto the tapered surface 202 of the connecting pipe 200, the gap between the fastening ring 401 and the tapered surface 202 is reduced by screwing in the fastening ring 400, thereby securing the end of the water pipe 300.

[0039] Preferably, the end of the fastening ring 400 away from the adapter 101 is fixedly connected to an anti-bending spring 402. The anti-bending spring 402 is sleeved on the outside of the water pipe 300. Therefore, after the water pipe leading out from the water pump interface passes through the anti-bending spring 402, due to the characteristics of the anti-bending spring 402, the water pipe will not bend excessively and affect the operation of the water pump.

[0040] In this embodiment, a connecting flange 500 is provided at the end of the fixing member 102 away from the adapter 101 for connecting to the interface flange on the water pump.

[0041] Example 2

[0042] Reference Figures 1-5 This is the second embodiment of the present invention, which is based on the previous embodiment and differs from the previous embodiment in that:

[0043] The adapter 101 has a plug shaft 101a at its end. The first channel A is located in the middle of the plug shaft 101a. The plug shaft 101a is cylindrical and has an annular groove 101b along its circumference. The fixing member 102 has a plug hole 102a, which is coaxial with the second channel B.

[0044] When connecting, the plug shaft 101a is inserted into the plug hole 102. The side of the plug hole 102a is provided with a radially extending guide groove 102b. A fixing block 103 is provided in the guide groove 102b. A first spring 104 is provided at the bottom of the fixing block 103 and the guide groove 102b. The fixing block 103 can be embedded in the annular groove 101b under the action of the spring.

[0045] The fixing block 103 has a chamfer 103a on its edge near the center end of the insertion hole 102a and near the opening of the insertion hole 102a, forming a bevel. When the insertion shaft 101a is inserted into the insertion hole 102, the insertion shaft 101a can push the chamfer 103a, causing the fixing block 103 to retract into the guide groove 102b. After the insertion shaft 101a is fully inserted into the insertion hole 102, the fixing block 103 pops out and is embedded in the annular groove 101b for fixation.

[0046] The fixed block 103 has a frustum 103b on both sides, and the guide groove 102b has a first long groove 102c extending along the moving direction of the fixed block 103. The frustum 103b is embedded in the first long groove 102c. The cooperation of the frustum 103b and the first long groove 102c can limit the moving range of the fixed block 103.

[0047] In this embodiment, the fixing block 103 and the guide groove 102b are symmetrically arranged in pairs.

[0048] The adapter 101 has a second long groove 101c extending radially inside. The position and number of the second long groove 101c are the same as those of the fixing block 103. The end face of the adapter 101 near the fixing block 102 has a third long groove 101d that penetrates the second long groove 101c. The outline of the third long groove 101d is smaller than that of the second long groove 101c, that is, the width of the third long groove 101d is smaller than that of the second long groove 101c.

[0049] A movable cylinder 105 is disposed within the second elongated groove 101c. The movable cylinder 105 is cylindrical and can move radially along the adapter 101 within the second elongated groove 101c. The movable cylinder 105 is provided with a through hole 105a, and a limiting pin 106 is disposed within the through hole 105a. The limiting pin 106 can move within the through hole 105a. The through hole 105a extends towards the axis from the side near the third elongated groove 101d to form a limiting edge. The inner diameter of the limiting edge is smaller than the inner diameter of the through hole 105a. The limiting pin 106 is located at one end of the through hole 105a to form a limiting block 106a, which prevents it from completely disengaging from the movable cylinder 105. In the initial state, the movable cylinder 105 and the limiting pin 106 are in a position close to the axis.

[0050] A second spring 106b is provided between the limiting block 106a and the end of the through hole 105a. Therefore, under the action of the second spring 106b, the limiting block 106a has a tendency to move outward.

[0051] The end of the fixing member 102 near the adapter 101 is provided with a strip groove 102d that intersects the guide groove 102b and extends radially. The position and size of the strip groove 102d correspond to the third long groove 101d. The fixing block 103 is provided with a limiting hole 103c. Therefore, when the adapter 101 and the fixing member 102 are connected, i.e., the fixing block 103 is embedded in the annular groove 101b, and the movable cylinder 105 and the limiting pin 106 are in a position close to the axis, the limiting hole 103c and the limiting pin 106 are coaxial. Under the action of the second spring 106b, the limiting pin 106 pops out and embeds into the limiting hole 103c, fixing the fixing block 103.

[0052] Furthermore, the adapter 101 has a circular groove 101e intersecting the second elongated groove 101c. An annular disk 107 is housed within the circular groove 101e, with a through hole at its center, making the entire interior of the adapter 101 permeable. The annular disk 107 has a spiral groove 107a. The annular disk 107 can rotate within the circular groove 101e, and the spiral groove 107a extends along the spiral path, with the spiral path of the spiral groove 107a centered on the center of the annular disk 107. The movable cylinder 105 passes through the spiral groove 107a. Therefore, when the annular disk 107 is rotated, the movable cylinder 105 can be driven to move radially. By default, in the initial state, the movable cylinder 105 is positioned near the center end within the spiral groove 107a.

[0053] The adapter 101 has a cylindrical groove 101f that communicates with the circular groove 101e. The annular disk 107 is connected to a cylinder 107b, which is integrally formed with the annular disk 107. The cylinder 107b is located inside the cylindrical groove 101f, and a spiral groove 107c is provided outside the cylinder 107b.

[0054] Correspondingly, the adapter 101 is provided with a fourth elongated groove 101g extending axially, which communicates with the cylindrical groove 101f. The adapter 101 is fitted with a disassembly ring 108, and a connecting rod 108a is provided inside the disassembly ring 108. The connecting rod 108a passes through the fourth elongated groove 101g and embeds into the spiral groove 107c. Therefore, by operating the axial offset of the disassembly ring 108, the cylinder 107b can be driven to rotate via the connecting rod 108a, thereby adjusting the position of the moving cylinder 105.

[0055] It should be noted that a protrusion 101h is provided on the outer periphery of the end of the adapter 101 near the fixing member 102, and a third spring 109 is provided between the protrusion 101h and the disassembly ring 108. That is, under the action of the third spring 109, the disassembly ring 108 is located away from the protrusion 101h and the fixing member 102, and at this time, the connecting rod 108a is located at the end of the spiral groove 107c, and the moving cylinder 105 is located at the end near the center in the spiral groove 107a.

[0056] When it is necessary to separate the adapter 101 and the fixing part 102, the disassembly ring 108 is operated to overcome the elastic force of the third spring 109 and move. Then, the connecting rod 108a drives the cylinder 107b to rotate. At this time, the annular disk 107 rotates and drives the moving cylinder 105 to move away from the adapter 101. Since the limiting pin 106 is embedded in the limiting hole 103c, the driving fixing block 103 is retracted into the guide groove 102b. At this time, the adapter 101 can be operated to make the connecting post 101a disengage from the insertion hole 102, thus completing the separation.
