[0024] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0025] A connection structure for connecting pipelines and water pumps, as shown in the reference. Figure 1 , Figure 2 and Figure 4 As shown, the device includes a water outlet connector 1 and a connecting pipe 2. The water outlet connector 1 is located on a water pump or other equipment that requires water output. One end of the connecting pipe 2 is connected to the water outlet connector 1, and the other end of the connecting pipe 2 is used to connect to a water pipe. The water outlet connector 1 is provided with a water outlet hole 3, and the connecting pipe 2 is provided with a connecting end 4 that is inserted into the water outlet hole 3. The water outlet hole 3 is circular, and the shape of the connecting end 4 is adapted to the water outlet hole 3.

[0026] A fixing ring 5 and a positioning part 6 are circumferentially arranged on the outer wall of the connecting end 4. The fixing ring 5 and the positioning part 6 are distributed along the axial direction of the connecting end 4, and a positioning groove 7 is formed between the fixing ring 5 and the positioning part 6. In one embodiment, the positioning part 6 includes a plurality of positioning blocks, which are evenly distributed along the circumferential direction of the connecting end 4. A positioning groove 7 is formed between the end of the positioning block and the fixing ring 5, and the upper surface of the positioning block abuts against the inner wall of the water outlet connector 1.

[0027] An abutment ring 8 is provided on the connection end 4, which is used to abut against the end face of the water outlet connector 1.

[0028] Reference Figure 3 As shown, at least one sealing groove 9 is provided on the connecting end 4. The sealing groove 9 is used to install the sealing ring. In this embodiment, there are two sealing grooves 9. The two sealing grooves 9 are distributed along the axial direction of the connecting end 4. The sealing groove 9 is closer to the end of the connecting end 4 than the fixing ring 5.

[0029] Thus, by fitting the sealing ring into the sealing groove 9, inserting the connecting end 4 into the water outlet hole 3 of the water outlet connector 1, abutting ring 8 abutting against the end face of the water outlet connector 1, and the upper surface of the positioning block abutting against the inner wall of the water outlet connector 1, the sealing ring waterproof seals the connection between the connecting end 4 and the water outlet hole 3. The connection between the connecting end 4 and the water outlet connector 1 is achieved through the above structure.

[0030] In order to prevent axial detachment between the connecting end 4 and the water outlet connector 1.

[0031] Reference Figure 1 and Figure 2 As shown, at least one snap-fit ​​groove 10 is provided on the water outlet connector 1. The snap-fit ​​groove 10 is elongated. In one embodiment, there are two snap-fit ​​grooves 10, which are respectively provided on both sides of the water outlet connector 1.

[0032] After the connecting end 4 is inserted into the water outlet hole 3, the snap-fit ​​groove 10 is opposite to the positioning groove 7. A snap ring 11 is fitted onto the water outlet connector 1. The snap ring 11 is semi-enclosed, and the lower end of the snap ring 11 is provided with a locking slot. The snap ring 11 can be opened outward through the locking slot, and then fitted onto the water outlet connector 1. The inner wall of the snap ring 11 is provided with locking feet 12. The number of locking feet 12 is the same as the number of snap-fit ​​grooves 10. The locking feet 12 are located on the inner walls of both sides of the snap ring 11.

[0033] When the retaining ring 11 is sleeved on the water outlet connector 1, the retaining foot 12 is inserted into the retaining groove 10 and extends into the positioning groove 7. The retaining foot 12 engages the positioning groove 7, thereby achieving axial anti-detachment between the connecting end 4 and the water outlet connector 1.

[0034] It is worth noting that the water outlet connector 1 is circumferentially provided with a first limiting ring 13 and a second limiting ring 14. The first limiting ring 13 and the second limiting ring 14 are arranged one after the other in the axial direction of the water outlet connector 1, forming a limiting gap between them. When the retaining ring 11 is received in the limiting gap to be sleeved on the water outlet connector 1, the aforementioned retaining groove 10 is provided in the limiting gap. The first limiting ring 13 has a movable opening 15, and limiting baffles 16 are provided on both sides of the movable opening 15. The retaining ring 11 is provided with a gripping piece 17, which is received in the movable opening 15. The gripping piece 17 and the movable opening 15 are used to limit the rotation range of the retaining ring 11 on the water outlet connector 1.

[0035] The locking foot 12 has guide edges 18 on both sides, and the locking groove 10 has guide slopes 19 on its groove wall. In one embodiment, both sides of the locking groove 10 have guide slopes 19. In another embodiment, one side of the locking groove 10 has a guide slope 19, and the other side of the locking groove 10 has a guide slope 19.

[0036] When it is necessary to connect the connecting pipe 2 to the water outlet connector 1, the connecting end 4 is inserted into the water outlet hole 3. At this time, the positioning groove 7 and the snap-fit ​​groove 10 are opposite each other. The snap ring 11 is sleeved on the water outlet connector 1, and the snap foot 12 on the snap ring 11 is inserted into the snap-fit ​​groove 10 and then extends into the positioning groove 7, thereby realizing the connection between the connecting pipe 2 and the water outlet connector 1. The installation is highly convenient.

[0037] When it is necessary to remove the connecting pipe 2 from the water outlet connector 1, simply remove the retaining ring 11 from the water outlet connector 1 or rotate the retaining ring 11 to disengage the retaining foot 12 from the positioning groove 7, and the connecting pipe 2 can be separated from the water outlet connector 1. The removal is also very convenient.

[0038] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
