Then, the anti-slip pads on both sides of the vertical plate are pressed, and the limiting cylinder is pushed to move under the support of the support rod and disengage from the U-shaped rod's slot, allowing the U-shaped rod to slide. At this time, the extension tube can slide freely. The U-shaped rod is adjusted as needed to drive the connecting block and the extension tube to extend outward. After adjusting to the appropriate position, the vertical plate is released, and the fixing spring pushes the limiting cylinder to snap into the U-shaped rod's slot, preventing the U-shaped rod from moving and thus locking the extension tube, achieving the purpose of adjustable valve body size.

[0016] 2.

[0026] The limiting mechanism 4 includes a telescopic spring 41. Two telescopic springs 41 are fixedly installed on the left side of the inner wall of the box 3. The elastic coefficient of the telescopic springs 41 can be set according to the requirements. A movable frame 42 is fixedly installed between the right ends of the two telescopic springs 41. A U-shaped plate 43 extending to the right side of the box 3 is fixedly installed on the right side of the movable frame 42. A pressing block 44 is fixedly installed on the right side of the U-shaped plate 43. A limiting gear 45 is fixedly installed on the right side of the movable frame 42. An auxiliary gear 46 that meshes with the limiting gear 45 is fixedly installed on the outer side of the valve stem 9. The pressing unlocking requires manual operation to avoid accidental contact that could cause the turntable 10 and the valve stem 9 to loosen.

[0027] The inner top wall of the box 3 has a round hole that matches the valve stem 9. A valve ball located inside the valve seat 1 is fixedly installed at one bottom end of the valve stem 9. A rectangular groove is opened on the left side of the moving frame 42, and the telescopic spring 41 is fixedly installed inside the rectangular groove.

[0028] The extension pipe mechanism 5 includes an extension pipe 51. An extension pipe 51 extending to the outside of the pipe body 2 is slidably installed on the inner side of the pipe body 2. A connecting flange 52 is fixedly installed at one end of the extension pipe 51. The pipe length can be adjusted through the extension pipe 51 and the connecting flange 52 to adapt to different installation requirements.

[0029] The connecting mechanism 7 includes a connecting block 71. The top and bottom of the extension tube 51 are fixedly installed with the connecting block 71. The opposite sides of the upper and lower connecting blocks 71 are fixedly installed with U-shaped rods 72. The U-shaped rods 72 pass through the fixing plate 6. The front and rear sides of the U-shaped rods 72 are fixedly installed with limit strips 73. The upper and lower U-shaped rods 72 are fixedly installed with arc plates 74.

[0030] The snap-fit ​​mechanism 8 includes a mounting groove 81. The top of the fixing plate 6 has a mounting groove 81. A rectangular plate 82 is fixedly installed inside the mounting groove 81. Support rods 83 are fixedly installed on both the front and rear sides of the rectangular plate 82. A limiting cylinder 84 is slidably installed on the outside of the support rods 83 and is slidably connected to the bottom wall of the mounting groove 81. One end of the limiting cylinder 84 extends to the inside of the fixing plate 6 and snaps with the U-shaped rod 72. A vertical plate 85 extending to the top of the fixing plate 6 is fixedly installed on the top of the limiting cylinder 84. A fixing spring 86 fixedly connected to the rectangular plate 82 is fixedly installed on one side of the vertical plate 85.

[0032] During use, the telescopic spring 41 ensures that the limiting gear 45 meshes with the auxiliary gear 46, restricting the rotation of the valve stem 9. Pressing the U-shaped plate 43 disengages the limiting gear 45 from the auxiliary gear 46, allowing the valve stem 9 to rotate. After the operation is completed, release the U-shaped plate 43 and relock it. Press the vertical plate 85 to disengage the limiting cylinder 84 from the slot of the U-shaped rod 72. Push the extension tube 51 to the required position, ensuring that the connecting flange 52 is aligned with the external pipeline. Relock it, release the vertical plate 85, and the fixing spring 86 pushes the limiting cylinder 84 into the slot, fixing the extension tube 51, thus completing the overall installation of the valve.

[0033] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0034] In summary, this extended docking structure valve, through the setting of the extension tube mechanism 5, fixing plate 6, connecting mechanism 7, and locking mechanism 8, allows for valve size adjustment as needed. First, the locking mechanism 8 is released from its limiting position on the connecting mechanism 7. Then, the anti-slip pads on both vertical plates 85 are pressed, pushing the limiting cylinder 84 to move under the support of the support rod 83 and disengage from the slot of the U-shaped rod 72, allowing the U-shaped rod 72 to slide. At this time, the extension tube 51 can slide freely. The U-shaped rod 72 is adjusted as needed, causing the connecting block 71 and the extension tube 51 to extend outwards. After adjusting to the appropriate position, the vertical plate 85 is released, and the fixing spring 86 pushes the limiting cylinder 84 into the slot of the U-shaped rod 72, preventing the U-shaped rod 72 from moving and thus locking the extension tube 51. This achieves the purpose of adjustable valve body size, allowing for flexible adjustment of the valve size during pipeline installation. The valve is designed to be 1 inch long, reducing on-site cutting and welding work. By pressing the pressing block 44 on the right side of the U-shaped plate 43 through the limiting mechanism 4, the moving frame 42 is pushed to the left, causing the limiting gear 45 to disengage from the auxiliary gear 46. At this time, the valve stem 9 can rotate freely, and the valve can be opened and closed by operating the turntable 10. When the pressing block 44 is released, the telescopic spring 41 pushes the moving frame 42 to reset, and the limiting gear 45 re-engages with the auxiliary gear 46, locking the valve. This achieves the purpose of having a self-locking structure, solving the problem of the valve being of constant size and unable to adjust the valve body size. If there is a certain size difference during installation, it is inconvenient to connect and install with external pipelines. In addition, without a corresponding self-locking structure, it is easy for external personnel to accidentally touch the valve when it is located outdoors, causing the water valve to open or loosen, resulting in unnecessary trouble.
