[0029] The mounting assembly 6 has a movable groove 61 reserved inside the rotating block 4, and the movable groove 61 is movably connected to the movable block 62 through a spring 1 63, and the movable block 62 matches the buckle groove 2 67 reserved inside the protrusion 3, and a pull rope 64 is fixedly connected to the end wall of the movable block 62, and the pull rope 64 is wound and connected with the rotating rod 65, and the rotating rod 65 is rotatably connected to the bottom wall of the groove 66 reserved inside the rotating block 4;

[0030] Auxiliary component 7, the outer ring of the rotating rod 65 is movably connected with a rotating disk 71, and the sliding groove 73 reserved inside the rotating disk 71 is rotatably connected with a sliding rod 74, the sliding rod 74 is movably connected to the vertical groove 76 through a spring 2 75, and the vertical groove 76 is connected to the channel 66.

[0031] The protrusion 3 is hexagonal, and the outer wall of the protrusion 3 is in contact with and slidably connected to the inner wall of the open buckle groove 5 at the bottom of the rotating block 4.

[0032] The movable block 62 is in a horizontal "T" shape. There are two movable blocks 62, and the two movable blocks 62 are symmetrically distributed with reference to the central axis of the rotating block 4 as the symmetry axis. The outer wall of the movable block 62 is in contact with the inner wall of the movable groove 61 and is slidably connected to ensure that the two movable blocks 62 move at the same time and match the second snap groove 67 reserved inside the protrusion 3, thereby ensuring the stability of the connection between the rotating block 4 and the valve stem 2.

[0033] One end of the spring 1 63 is fixedly connected to the "T"-shaped end wall of the movable block 62, and the other end of the spring 1 63 is fixedly connected to the inner wall of the movable groove 61 to ensure the subsequent movement and reset movement of the movable block 62.

[0034] The rotating rod 65 is composed of a square rod and a columnar rod that are fixedly connected, and a pull rope 64 is wrapped around the outer ring of the columnar rod. In this way, a special-shaped latch is required to drive the rotating rod 65 to rotate, thereby preventing the entire valve body 1 from being dismantled.

[0035] The outer wall of the turntable 71 is in contact with the inner wall of the groove 66 and is connected by sliding up and down. A square groove 72 is reserved inside the turntable 71, and the inner wall of the square groove 72 is in contact with the outer wall of the square rod in the rotating rod 65 and is connected by sliding up and down to ensure the rotation connection between the turntable 71 and the sliding rod 74. At the same time, the sliding rod 74 moves up and down to drive the turntable 71 to move and then open the top opening of the groove 66.

[0036] The sliding rod 74 is in a horizontal "T" shape. There are two sliding rods 74. The two sliding rods 74 are symmetrically arranged with reference to the central axis of the turntable 71 as the symmetry axis. The outer wall of the "T"-shaped end of the sliding rod 74 is in contact with the inner wall of the slide groove 73 and is slidably connected.

In the initial state of the second spring 75, the top of the groove 66 is in a closed state.

[0038] Working principle: when using an anti-disassembly valve, first, when the internal staff needs to disassemble the rotating block 4 and the valve body 1 for maintenance, they insert the special latch into the interior of the groove 66, and the lower end of the latch abuts against the turntable 71. At this time, the turntable 71 moves downward in the groove 66. Then, when the internal insertion hole of the latch matches the square rod of the rotating rod 65 for a distance, the latch can be rotated to mobilize the rotation of the entire rotating rod 65 (the rotation of the rotating rod 65 will mobilize the rotation of the entire turntable 71, and the turntable 71 is rotatably connected with the sliding rod 74, so as to ensure that the sliding rod 74 will not affect the rotation of the turntable 71). The rotating rod 65 rotates to reel in the pull rope 64 wound around the outer ring of the columnar rod of the rotating rod 65. At this time, the pull rope 64 pulls the movable block 62 to move toward the inside of the movable groove 61 and then leaves the inside of the buckle groove 5. At this time, it is convenient to remove the rotating block 4;

[0039] In the initial state, spring 2 75 applies force to support the sliding rod 74 at the top of the vertical groove 76, so that the turntable 71 slidably connected to the sliding rod 74 is at the top of the groove 66, and the top of the groove 66 is in a closed state. A special latch is required to assist the rotation of the special-shaped rotating rod 65, which has a good anti-dismantling effect. In this way, it can prevent dismantling from outsiders and ensure that internal staff do not interfere with each other when repairing the valve body 1.

[0040] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
