[0002] Referring to the patent document with application number "CN202022671771.7" and titled "A valve connector with good sealing performance", this patent document can reduce the gap between the external connecting head and the water outlet and water inlet through the silicone pad. At the same time, through the cooperation of structures such as the second limit block and the first limit block, the stability of the silicone pad during connection can be greatly enhanced, and the silicone pad is prevented from loosening due to the impact of water flow, thereby further enhancing the sealing effect, effectively solving the problem of leakage after long-term use, and improving the use effect of the device.

[0021] Reference Figure 1-Figure 4 A high-sealing valve joint with an anti-loosening structure includes a main body 1. The main body 1 and the auxiliary body 2 are valve joints in the prior art. The auxiliary body 2 is connected to the pipeline itself, and the main body 1 is the main docking component of the valve joint. The closing ring 3 is a manual tightening component in the prior art. The connection between the main body 1 and the auxiliary body 2 can be tightened by rotating it to reduce water leakage between the main body 1 and the auxiliary body 2. The closing ring 3 is mostly made of plastic material, which is inexpensive and does not affect the later use cost.
[0022] The closed ring 3 is provided with a plurality of internal threads 4 for improving the connection effect between the main pipe body 1 and the auxiliary pipe body 2. The internal threads 4 are mainly provided on the closed ring 3 and cover the inner wall of the closed ring 3, so that the closed ring 3 can be quickly tightened to reduce the time wasted on the rotation angle. The main pipe body 1 is provided with an outer ring, which protrudes from the outer wall of the main pipe body 1 and is arranged as a whole on the side of the main pipe body 1 facing the auxiliary pipe body 2, so as to facilitate docking with the closed ring 3. The outer ring is provided with a plurality of external threads 5, which are in a protruding state and cover the outer wall of the outer ring. The external threads 5 are adapted to the internal threads 4. The external threads 5 are rotated on the auxiliary pipe body 2 through the main pipe body 1 so that they are clamped with the internal threads 4. In order to improve the sealing effect, raw rubber tape can be wrapped around the external threads 5 to improve the water-proof effect, and the outer ring is abutted against the inner wall of the closed ring 3. After the outer ring is docked with the closed ring 3, the outer wall of the outer ring is tightly abutted against the inner wall of the closed ring 3.
[0023] A plurality of arc rods 7 for connecting the auxiliary tube body 2 are provided on the main tube body 1. The arc rods 7 are in a semicircular shape and are mainly used for connecting the main tube body 1 and the auxiliary tube body 2 to improve the connection relationship between the two and reduce looseness. The arc rods 7 are fixedly connected to the main tube body 1 through support rods 6. The support rods 6 are auxiliary components and are mainly used to fix the arc rods 7 on the main tube body 1. The lengths of the support rods 6 and the arc rods 7 depend on the depth of the slide groove 9. The support rods 6 are fixedly connected to the main tube body 1 through fasteners. The fasteners are used in combination with traceless nails to fix the support rods 6 to the outer wall of the main tube body 1.
[0024] An arc groove 8 is provided on the arc rod 7 for the main body 1 to rotate on the auxiliary tube body 2. The arc groove 8 is opened for the arc rod 7 to slide in the slide groove 9. The arc groove 8 is opened on the inner side of the arc rod 7, and the arc groove 8 is opened on one side of the arc rod 7, and the arc groove 8 is not equal to the other side, so that the main body 1 can only be clamped and connected by clockwise rotation, and the arc groove 8 runs through the support rod 6. The length of the arc groove 8 extends to the support rod 6 on the outer wall of the main body 1, so that after the main body 1 is connected to the auxiliary tube body 2, the support rod 6 is adapted to the slide groove 9.
[0025] A rubber sheet 10 is provided on the auxiliary pipe body 2 to improve the sealing performance of the connection with the main pipe body 1. The rubber sheet 10 is used in the prior art to improve the sealing effect between the valve joint and the main pipe to reduce water leakage between the two. A circular groove is provided on the main pipe body 1. The circular groove is provided on the outer wall of the main pipe body 1 and is in an inwardly concave arc shape. The rubber sheet 10 is fixedly connected to the auxiliary pipe body 2 through a fastener. The fastener is a special fixing component for rubber products. The rubber sheet 10 is arc-shaped and matches the circular groove, which facilitates the main pipe body 1 to rotate on the auxiliary pipe body 2.
[0026] The auxiliary tube body 2 is provided with a clamping groove 12 for limiting the arc rod 7. The clamping groove 12 is used to limit the arc rod 7 so that the arc rod 7 is fixed to the clamping groove 12 in a rotating state, so as to prevent the main tube body 1 from being subjected to impact due to the external environment, causing the main tube body 1 to rotate in the opposite direction, resulting in looseness of the main tube body 1 and the auxiliary tube body 2, thereby causing water leakage and loosening of the device. A plurality of slide grooves 9 are provided on the auxiliary tube body 2. The slide groove 9 is used for the arc rod 7 to slide in the auxiliary tube body 2 and limit the arc rod 7 to reduce the disconnection between the main tube body 1 and the auxiliary tube body 2. A convex point 11 for the sliding of the arc groove 8 is provided on the slide groove 9. The convex point 11 is arranged at the front end of the slide groove 9 and extends along the curvature of the slide groove 9 to the clamping groove 12. The convex point 11 is adapted to the arc groove 8 of the arc rod 7, and the clamping groove 12 is connected to the slide groove 9.
[0027] The working principle of the utility model is as follows: first, the auxiliary pipe body 2 is fixed on the main pipe, and then the main pipe body 1 is manually removed, and the arc rod 7 on the main pipe body 1 is inserted into the slide groove 9, and the arc rod 7 is kept pressed to make the arc rod 7 slide deeper into the slide groove 9. When the arc rod 7 is pressed against the inner wall of the slide groove 9, the main pipe body 1 can be rotated to make the arc rod 7 slide in the slide groove 9 and reach the clamping groove 12 to complete the restriction. Finally, the connection between the main pipe body 1 and the auxiliary pipe body 2 is sealed by the closed ring 3.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
