[0030] The tee 103 is a pipe connector, which is mainly used to divert two branch pipes from a main pipe to achieve the diversion of the pipe. It can divide a pipe into two or more directions and control the flow in each direction.

[0036] When the water pipe 101 needs to be connected, the water pipe 101 is first inserted into one side of the tee pipe 103. A sealing ring is sleeved on the outside of the water pipe 101 to ensure the sealing of the water pipe 101 when it is connected. After the water pipe 101 is inserted into the tee pipe 103, the moving rod 201b is moved, and the moving rod 201b drives the block 201a to move, so that the block 201a moves to one side of the water pipe 101 to squeeze the water pipe 101, so that the water pipe 101 can be fixed.

[0037] Specifically, the mounting member 201 further includes a movable bar 201c and a movable frame 201d. The movable bar 201c is fixed to one side of the movable rod 201b. The movable frame 201d is sleeved on the outside of the movable bar 201c. The movable frame 201d and the movable bar 201c are movably connected.

[0038] When the moving rod 201b needs to be moved, the moving frame 201d is moved. The movement of the moving frame 201d can drive the moving bar 201c to move. At this time, the movement of the moving bar 201c can drive the moving rod 201b to move.

[0039] Specifically, the mounting member 201 further includes a rotating disk 201e, the rotating disk 201e is disposed on one side of the connecting pipe 102, and the moving frame 201d is fixed on one side of the rotating disk 201e.

[0040] The moving frame 201d can be driven to move by rotating the rotating disk 201e, and the movement of the moving frame 201d will drive the movable bar 201c to move. The rotating disk 201e can also support the moving frame 201d to prevent the moving frame 201d from deflecting.

[0041] Specifically, the mounting member 201 further includes a connecting bar 201f and a sliding block 201g. The connecting bar 201f is fixed to one side of the moving rod 201b, and the sliding block 201g is fixed to one end of the connecting bar 201f.

[0042] When the movable bar 201c moves, it will drive the connecting bar 201f to move, and the connecting bar 201f will drive the sliding block 201g to move. At this time, the movable bar 201c can be supported by supporting the sliding block 201g to prevent the movable bar 201c from deflecting.

[0043] Specifically, the mounting member 201 further includes a supporting frame 201h and a positioning block 201i. The supporting frame 201h is sleeved on the outside of the slider 201g.

[0044] A slot is also provided in the support frame 201h, and the slider 201g slides in the slot. When the connecting strip 201f drives the slider 201g to move, it will drive the slider 201g to slide in the slot. At this time, the slider 201g can be supported, and the rotating disk 201e can be supported to prevent the rotating disk 201e from falling off. The positioning block 201i is fixed to one side of the connecting tube 102. The support frame 201h can be supported by the setting of the positioning block 201i to prevent the support frame 201h from offset.

[0046] A limiting groove corresponding to the limiting rod 202b is provided on the limiting frame 202a. When the water pipe 101 is fixed, the limiting rod 202b can be driven to slide on the limiting groove by rotating the rotating disk 201e. After the water pipe 101 is fixed, the limiting rod 202b can be limited by the setting of the limiting groove, thereby preventing the rotating disk 201e from reversing and causing the fixation of the water pipe 101 to loosen.

[0047] Example 3

[0048] Reference Figure 4 and Figure 5 , which is the third embodiment of the utility model, and this embodiment is based on the first two embodiments.

[0049] Specifically, the limiting member 202 further includes a movable disk 202c and a fixed plate 202d. The movable disk 202c is fixed to one end of the limiting rod 202b. The fixed plate 202d is rotatably connected to one end of the movable disk 202c through a bearing. The fixed plate 202d is fixed to one side of the rotating disk 201e.

[0050] When the water pipe 101 needs to be removed, the movable disk 202c is rotated, and the rotation of the movable disk 202c will drive the limiting rod 202b to separate from the limiting groove. At this time, the limit on the rotating disk 201e can be released, so that the rotating disk 201e can be reversed. The fixed plate 202d is used to support the movable disk 202c to prevent the movable disk 202c from deflecting.

[0051] Specifically, the limiting member 202 further includes a torsion spring 202e, one end of which is fixed to one side of the movable disk 202c, and the other end of which is fixed to one side of the fixed plate 202d.

[0052] When the movable disk 202c is rotated, a torsional force can be applied to the torsion spring 202e. The rotation of the movable disk 202c will drive the limit rod 202b to separate from the limit groove. At this time, the limit on the rotating disk 201e can be released. After the water pipe 101 is removed, the movable disk 202c is loosened. At this time, the force of the rotation of the torsion spring 202e will drive the limit rod 202b to re-engage with the limit groove.

[0053] Specifically, the limiting member 202 further includes a spring 202f and a connecting plate 202g, the spring 202f is fixed to one side of the fixing plate 202d, the connecting plate 202g is fixed to one end of the spring 202f, and the connecting plate 202g is fixed to one side of the positioning block 201i.

[0054] When the rotating disk 201e is rotated, the fixed plate 202d will be driven to move. At this time, the movement of the fixed plate 202d will apply a pulling force to the spring 202f. The rotation of the rotating disk 201e will fix the water pipe 101. When the water pipe 101 needs to be removed, the limit on the rotating disk 201e is released. At this time, the rebound force of the spring 202f can drive the rotating disk 201e to rotate, so that the water pipe 101 can be removed. The connecting plate 202g is used to fix the spring 202f to prevent the spring 202f from deflecting.

[0055] During use, when the water pipe 101 needs to be installed, first insert the water pipe 101 into one side of the three-way pipe 103. At this time, the water pipe 101 needs to be fixed by rotating the rotating disk 201e. When the rotating disk 201e is rotated, the fixed plate 202d will be driven to move. At this time, the movement of the fixed plate 202d will apply a pulling force to the spring 202f. The rotation of the rotating disk 201e will drive the moving frame 201d to move. The movement of the moving frame 201d can drive the movable bar 201c to move. When the movable bar 201c moves, it will drive the connecting bar 201f to move. The connecting bar 201f will drive the slider 201g to move. When the connecting bar 201f drives the slider 201g to move, it will drive the slider 201g When sliding in the card slot, the slider 201g can be supported, and the rotating disk 201e can be supported to prevent the rotating disk 201e from falling off. The movable bar 201c can drive the moving rod 201b to move by moving, and the moving rod 201b drives the block 201a to move, so that the block 201a moves to the side of the water pipe 101 to squeeze the water pipe 101, and the rotating disk 201e will drive the limiting rod 202b to slide on the limiting slot when rotating. After the water pipe 101 is fixed, the limiting rod 202b can be limited by the setting of the limiting slot, thereby preventing the rotating disk 201e from reversing and causing the fixation of the water pipe 101 to loosen, thereby fixing the water pipe 101.

[0056] When the water pipe 101 needs to be removed, the movable disk 202c is rotated. When the movable disk 202c is rotated, a torsional force can be applied to the torsion spring 202e. The rotation of the movable disk 202c will drive the limit rod 202b to separate from the limit groove, thereby releasing the limit on the rotating disk 201e. At this time, the rebound force of the spring 202f can drive the rotating disk 201e to rotate, so that the water pipe 101 can be removed. After the water pipe 101 is removed, the movable disk 202c is released. At this time, the force of the rotation of the torsion spring 202e will drive the limit rod 202b to re-engage with the limit groove for next use.
