[0023] A sliding bearing 22 is provided between the inner wall of the limiting sleeve 18 and the outer wall of the right end of the guide rod 12; the outer wall of the left end of the sliding bearing 22 is provided with a pressure portion 23 that fits with the left side wall of the locking portion 20; the cleaning spring 17 is located between the left side wall of the pressure portion 23 and the right side wall of the partition 9.

[0024] An auxiliary conical surface 24 is provided on the inner edges of both ends of the scraper 15 , and the diameter of the auxiliary conical surface 24 gradually decreases in the direction away from the middle of the scraper 15 .

[0025] The outer wall of the left end of the connector 2 and the outer wall of the right end of the connector body 1 are both provided with external threads 25 .

[0026] A screw hole 26 is provided at the center of the right side wall of the partition 9 , and the left end of the guide rod 12 is screwed into the screw hole 26 ; the limit head 13 is in a regular hexagon.

[0027] An annular sealing groove 27 is provided on the left side wall of the limiting portion 3 ; a matching sealing ring 28 is provided in the sealing groove 27 .

[0028] The outer diameter of the limiting head 13 is smaller than the outer diameter of the limiting sleeve 18 .

[0029] The method of using the utility model is as follows:

[0030] The outer wall of the left end of the connector 2 and the outer wall of the right end of the connector body 1 are both provided with external threads 25. This structural design facilitates the connection between the connector 2, the connector body 1 and the pipeline. It can be connected to one of the pipelines through the left end of the connector 2, and can be connected to another pipeline through the right end of the connector body 1. At this time, two independent pipelines are connected together.

[0031] When the water in the pipe connected to the joint body 1 flows into the joint body 1, the water will flow to the left toward the water hole 10 through the gap between the adjacent support rods 16. Under the elasticity of the reset spring 8, there is a gap between the right side wall of the limiting part 3 and the left end face of the joint body 1, so that there is a gap between the right end face of the connector 2 and the left side wall of the partition 9. At this time, the water in the joint body 1 can flow into the connector 2 through the water hole, the gap between the right end face of the connector 2 and the left side wall of the partition 9 in turn, and finally flow into the pipe connected to the connector 2 from the left end port of the connector 2, thereby realizing water transportation.

[0032] When it is necessary to clean the impurities adhering to the inner wall of the joint body 1, you can first rotate the connector 2 with a wrench that matches the positioning notch 11. Since the connector 2 is threadedly connected to the pipe end, after the connector 2 is rotated to a certain extent, the connector 2 still remains connected to the pipe end. At the same time, the right end face of the connector 2 continues to approach the left side wall of the partition 9, and the return spring 8 is compressed, and the left and right ends of the return spring 8 are respectively stuck at the bottom of the left limit groove 6 and the bottom of the right limit groove 7. At this time, the left limit groove 6 and the right limit groove 7 can be used to accommodate the compressed return spring 8, so that the right end face of the connector 2 can fit with the left side wall of the partition 9, thereby blocking and sealing the left end opening of the water hole 10 through the right end face of the connector 2. At this time, the water flow in the joint body 1 cannot be transported through the connector 2 to the pipe connected to the connector 2, and the water flow is retained in the joint body 1.

[0033] Next, the impurities adhering to the inner wall of the joint body 1 can be cleaned. Since the pipeline connected to the joint body 1 is responsible for water intake, there will be an on-off switch for controlling the water flow. By simply turning the on-off switch on and off, the sleeve 14 can slide left and right, thereby realizing the left and right sliding of the scraper 15. When the scraper 15 slides left and right, the impurities adhering to the inner wall of the joint body 1 will be scraped off, and then as the drain cover 30 is opened, the impurities cleaned out of the joint body 1 will be flushed out to the outside through the drain joint 29 with the water flow, achieving a cleaning effect. After the impurities are cleaned, the drain cover 30 is screwed onto the drain joint 29 again, and the connector 2 is moved left and reset, and the pipe joint can restore the effect of connecting the two pipes.

[0034] When the left end opening of the water hole 10 is blocked and sealed, as the water in the pipe connected to the joint body 1 rushes to the left into the joint body 1, the water will simultaneously impact the limit nut 21 and the support rod 16. At this time, under the impact force and the lubrication of the sliding bearing 22, the limit sleeve 18 will move the sleeve 14 to the left along the trajectory of the guide rod 12, and the cleaning spring 17 will be compressed and generate elasticity. When the sleeve 14 moves to the left, the scraper 15 moves to the left synchronously to scrape off impurities adhering to the inner wall of the joint body 1. When the water flow into the joint body 1 is closed and the water pressure is lost, the cleaning spring 17 will use its own elasticity to reset the scraper 15 to the right. During the right movement of the scraper 15, the impurities adhering to the inner wall of the joint body 1 will be scraped off again, thereby ensuring the cleaning quality to the greatest extent.

[0035] From the above, it can be seen that the utility model can adjust the position of the connecting head 2 through the positioning notch 11, close the joint body 1, and use the pressure of the water flow to realize the left and right movement of the scraper 15. During the movement of the scraper 15, the impurities adhering to the inner wall of the joint body 1 are scraped off, and finally the scraped impurities are discharged from the joint body 1 using the sewage discharge joint 29, effectively avoiding the impurities constantly adhering to the inner wall of the joint body 1 and causing the joint body 1 to be blocked, ensuring the normal transportation of water flow, and the entire process of cleaning impurities does not require separating the pipe joint from the ends of the two pipes, reducing a lot of trouble and effectively improving the cleaning efficiency. At the same time, it can effectively avoid the pipe joint being removed, causing the ends of the two pipes to be exposed to the outside world, thereby causing the inside of the pipe to be contaminated.

[0036] A rotary bearing 19 is provided between the outer wall of the limiting sleeve 18 and the inner wall of the sliding sleeve 14. The rotary bearing 19 can be made of plastic, ceramic or steel, etc., which can effectively ensure the service life of the rotary bearing 19 when used in water.

[0037] A sliding bearing 22 is provided between the inner wall of the limiting sleeve 18 and the outer wall of the right end of the guide rod 12. The sliding bearing 22 is a water-lubricated bearing, which can effectively ensure the smoothness of the limiting sleeve 18 and the sliding sleeve 14 when sliding along the guide rod 12, thereby ensuring the smoothness of the scraper 15 when removing impurities.

[0038] An auxiliary conical surface 24 is provided on the inner edges of the left and right ends of the scraper 15. The diameter of the auxiliary conical surface 24 gradually decreases towards the direction away from the middle of the scraper 15. The existence of the auxiliary conical surface 24 can make the two ends of the scraper 15 have sharp edges, which can more easily scrape off impurities on the inner wall of the joint body 1.

[0039] A screw hole 26 is provided in the center of the right side wall of the partition 9. The left end of the guide rod 12 is screwed into the screw hole 26. The limit head 13 is a regular hexagon. The limit head 13 can be easily rotated by using an Allen wrench that matches the limit head 13, so that the right end of the guide rod 12 can be easily unscrewed from the screw hole 26, thereby realizing rapid disassembly and assembly of the guide rod 12 and other components.

[0040] An annular sealing groove 27 is provided on the left side wall of the limiting part 3, and a matching sealing ring 28 is provided in the sealing groove 27. When the pipe joint is normally connected to the two pipes, the presence of the sealing ring 28 can effectively ensure the sealing between the left side wall of the limiting part 3 and the right side wall of the extrusion part 5, thereby ensuring the sealing between the connecting head 2 and the adjusting nut 4.

[0041] The outer diameter of the limiting head 13 is smaller than the outer diameter of the limiting sleeve 18, ensuring that the water flow can impact the limiting nut 21 to the left, and ensuring that the scraper 15 can move with the impact force of the water flow.
