Description

Technical Field

[0001] The utility model relates to the technical field of drainage pipe connection, in particular to a drainage pipe connector. Background Art

[0002] As the lifeline for transporting domestic water, water pipes have injected vitality and convenience into society. The relay of the drainage pipe system has built an invisible channel for wastewater discharge, ensuring the hygiene of the environment and the health of residents. The two together maintain the cleanliness and comfort of modern life. In this precise water circulation mechanism, drainage pipe connectors play an indispensable role. They are like delicate "hubs". Through the turning of elbows and the sealing of joints, they ensure that every node of the drainage network can be closely connected and operate smoothly. The sophisticated design and layout of these connectors not only overcome the complexity of the building structure, but also effectively prevent water leakage and pollution, improve the overall efficiency and durability of the drainage system, and further consolidate the modern concept of rational use of water resources and environmental protection.

[0003] As time goes by, the connecting parts of the drainage pipe system will face the problem of dirt gradually accumulating on the inner wall. Day after day, grease, debris, mineral deposits, etc. continue to accumulate inside the pipe, especially in complex structural parts such as elbows and joints, which are more likely to become hiding places for dirt. These accumulated dirt will not only gradually reduce the inner diameter of the pipe, affecting the smooth flow of water, but in severe cases will completely block the pipe, resulting in poor drainage and causing great inconvenience to family life. In addition, small objects such as rings, earrings and other commemorative items may occasionally fall into the pipe accidentally in daily life, causing property losses and making people very upset. How to invent a drainage pipe connector to improve these problems has become an urgent problem to be solved by technicians in this field. Utility Model Content

[0025] Reference Figure 4-Figure 8The cleaning mechanism includes a short plate 12 fixedly connected to the outer wall of the central shaft 7, a through-hole scraper 11 is fixedly connected to the outer wall of the central shaft 7, a plurality of hexagonal through holes 14 are provided on the surface of the through-hole scraper 11, an elastic scraper 10 is slidably provided on the outer wall of the short plate 12, the elastic scraper 10 and the short plate 12 are elastically connected by a spring 16, a wire drawing 15 is fixedly connected to one side of the short plate 12, the end of the wire drawing 15 is fixedly connected to the elastic scraper 10, the outer contours of the elastic scraper 10 and the through-hole scraper 11 are blade-shaped, which brings a better cleaning effect, the blade-shaped outer contour of the elastic scraper 10 is slidably set with the inner wall of the circular cavity 13, the blade-shaped outer contour of the through-hole scraper 11 is slidably set with the inner wall of the circular cavity 13, and the central shaft 7 is driven to rotate by turning the knob 3. The through-hole scraper 11 and the elastic scraper 10 rotate, further driving the through-hole scraper 11 and the elastic scraper 10 to rotate. The elastic scraper 10 performs preliminary processing on the inner wall of the circular cavity 13. The knob 3 is rotated to the position of the second scale 5, and the through-hole scraper 11 begins to intervene and scrape the inner wall of the circular cavity 13. The overall design of the through-hole scraper 11 makes the structure more stable, and the hard dirt remaining on the inner wall of the circular cavity 13 is cleaned more thoroughly, reducing the problem of water pipe blockage caused by dirt accumulation; after the cleaning is completed, when the knob 3 is rotated to the position of the third scale 6, the through-hole scraper 11 and the elastic scraper 10 block the water flow channel, and the water flow can only flow out from the hexagonal through holes 14 of the through-hole scraper 11, blocking valuables that accidentally fall into the water pipe and preventing them from entering the urban public sewage system, thereby avoiding property loss.

[0026] The working principle of the drainage pipe connector is as follows: water flows in from the water inlet 17 and is discharged from the water outlet 18. Dirt is easily accumulated at the turning point of the curved pipe. The knob 3 is turned clockwise to drive the central axis 7 to rotate, and further drive the through-hole scraper 11 and the short plate 12 to rotate. The short plate 12 drives the elastic scraper 10 to rotate. The elastic scraper 10 scrapes and cleans the inner wall of the circular cavity 13 during the rotation process. When encountering hard dirt accumulated, the dirt surface squeezes the elastic scraper 10, and the elastic scraper 10 squeezes the spring 16 to avoid damage to the elastic scraper 10. Continue to rotate the knob 3 to the position of the second scale 5, and the through-hole scraper 11 starts to scrape the inner wall of the circular cavity 13. The through-hole scraper 11 The inner wall of the shaped cavity 13 is cleaned more thoroughly. After the cleaning is completed, when the knob 3 is rotated to the position of the third scale 6, the through-hole scraper 11 and the elastic scraper 10 block the water flow channel, and the water flow can only flow out from the hexagonal through hole 14 of the through-hole scraper 11, thereby blocking valuables that accidentally fall into the water pipe to prevent them from falling into the public sewage system; rotate the knob 3 clockwise, the elastic scraper 10 pushes the elastic shock rod 19 to store force for the torsion spring 21 on the shock rod pin 20, and after the elastic scraper 10 passes over the elastic shock rod 19, the torsion spring 21 on the shock rod pin 20 will push the elastic shock rod 19 to rebound downward and hit the through-hole scraper 11, and the dirt on the through-hole scraper 11 falls off through vibration, thereby maintaining the cleanliness of the through-hole scraper 11.

[0027] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.
