[0024] The valve body 1 and the interface 14 used in this application are products that can be directly purchased on the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described here in detail.

[0025] A multi-way valve that is easy to disassemble, comprising: a valve body 1, a mounting groove 11 is provided on the top surface of the valve body 1, and an interface 14 is provided on the inner side of the mounting groove 11;

[0026] Insertion holes 12 are provided on the front and rear inner walls of the installation slot 11, and positioning slots 13 are provided on the left and right side walls of the installation slot 11;

[0027] The inner side of the mounting groove 11 is provided with a mounting structure 2, which includes a mounting plate 21. The mounting plate 21 is mounted on the inner side of the positioning groove 13 of the mounting groove 11. A movable groove 22 is provided on the front and rear surfaces of the mounting plate 21. Two sets of movable plates 23 are slidably mounted on the front and rear ends of the inner side of the movable groove 22. A card slot 24 is provided on the surface of the movable plate 23. A spring 25 and a card block 26 are fixedly connected to the two sides of the movable plate 23 respectively. A transmission rod 27 is movably mounted on the inner side of the movable groove 22 through a bearing. The transmission rod 2 Two sets of sector blocks 28 are fixedly connected to the middle of 7, and worm gears 29 are fixedly connected to both ends of the transmission rod 27. A hand-rotating worm 210 is movably installed on the top surface of the mounting plate 21 through a bearing. By rotating the hand-rotating worm 210, the movable plate 23 can be driven to telescope in the mounting plate 21 through the spring 25 and the transmission rod 27, so that the block 26 can be inserted into or pulled out of the socket 12, which can realize the convenient disassembly and assembly of the mounting plate 21 on the valve body 1, so that the interface 14 is exposed, which is convenient for maintenance of the interface 14.

[0028] Furthermore, the mounting structure 2 is installed inside the interface 14 , and the mounting structure 2 can be expanded inside the interface 14 to block the gap between the interfaces 14 , ensure the sealing of the inside of the mounting groove 11 , and extend the service life of the interface 14 .

[0029] Furthermore, the movable plate 23 is exposed inside the movable groove 22 , and the inner wall of the card slot 24 fits with the outer wall of the interface 14 . The movable plate 23 cooperates with the card slot 24 to ensure the tightness of the fit between the mounting structure 2 and the interface 14 and avoid the generation of gaps.

[0030] Furthermore, one end of the spring 25 is fixedly connected to the inner wall of the movable groove 22, and the block 26 is inserted into the inside of the socket 12. The spring 25 provides power for the movable plate 23 to reset inside the movable groove 22. The block 26 cooperates with the socket 12 to ensure the installation stability of the mounting plate 21 in the mounting groove 11.

[0031] Furthermore, the transmission rod 27 is located between the two groups of movable plates 23, and the two groups of fan-shaped blocks 28 are set at 180° to each other. The surface of the fan-shaped block 28 is in contact with the surface of the movable plate 23. The rotation of the fan-shaped block 28 can drive the two groups of movable plates 23 to move toward each other, so as to push the movable plate 23 to extend from the movable groove 22 to block the inner side of the mounting groove 11.

[0032] Furthermore, the bottom end of the hand-rotating worm 210 is engaged with the worm wheel 29 , and rotating the hand-rotating worm 210 can drive the worm wheel 29 to rotate, thereby providing power for the rotation of the sector block 28 .

[0033] Working principle: During installation, the mounting plate 21 is placed downwardly on the inner side of the positioning groove 13, and then the hand-rotating worm 210 is rotated. The hand-rotating worm 210 is threadedly connected to the worm gear 29. The rotation of the hand-rotating worm 210 drives the sector block 28 to rotate through the worm gear 29 and the transmission rod 27. When the sector block 28 rotates, the outer end will push the movable plate 23, so that the two sets of movable plates 23 move away from each other, and the movable plate 23 extends from the movable groove 22 and is blocked on the inner side of the mounting groove 11. The movable plate 23 cooperates with the movable groove 22 to protect the interior of the valve body 1 on the upper side, and the block 26 on the surface of the movable plate 23 will be inserted into the insertion hole 12, which can enhance the installation stability of the mounting structure 2 on the valve body 1 and avoid loosening. The card groove 24 will be stuck on the outer side of the interface 14, which can ensure that the movable plate 23 fits tightly with the interface 14 to avoid gaps.

[0034] When the docking port 14 needs to be repaired, the hand-rotating worm 210 is rotated in the opposite direction. The hand-rotating worm 210 drives the sector block 28 to flip through the worm gear 29 and the transmission rod 27. The sector block 28 releases the contact with the movable plate 23. The movable plate 23 slides along the inner end of the sector block 28, and the movable plate 23 is pulled into the movable groove 22 under the elastic action of the spring 25. The block 26 is pulled out from the socket 12, and the fixation of the mounting structure 2 on the valve body 1 can be released. The mounting structure 2 can be removed, so that the inner side of the mounting groove 11 is exposed, which is convenient for maintenance of the docking port 14, convenient operation, and more practical.
