The shoulder 443 is located on the positioning tube 42.

Referring to FIGS. 3 and 4, the connecting pipe group 5 is used to connect the pipe plug 9 and the leak-proof gasket 4. The connecting pipe group 5 includes a through-hole 43 threaded through the leak-proof gasket 4 and the top end is screwed to The connecting pipe 51 of the pipe plug 9 and a nut 52 screwed to the connecting pipe 51 and accommodated in the large aperture section 442 of the through hole 43 of the leak-proof gasket 4. The connecting pipe 51 has a pipe body 511 passing through the through hole 43 and a stopper portion 512 extending radially outward from the pipe body 511 and higher than one of the inner flanges 221 of the saddle strap 2. The tube body 511 has a connecting external thread 513 and a fixed external thread 514 which are reversely arranged along the direction of the axis L. The connecting external thread 513 is higher than the baffle portion 512 and is screwed to the internal thread of the pipe bolt 9, and the fixed external thread 514 is lower than the baffle portion 512. The nut 52 is screwed to the fixed external thread 514 and abuts against the shoulder 443 of the leak-proof washer 4. Preferably, the nut 52 is only partially screwed to the connecting tube 51. Preferably, the connecting tube set 5 further includes a set of spacers 53 disposed on the tube body 511 and sandwiched between the baffle portion 512 and one of the saddle straps 2, which can be improved by the spacers 53 In other modified examples, the connection strength between the connection pipe 51 and the leak-proof gasket 4 can omit the gasket 53 and allow the stopper portion 513 to directly abut the tip of the leak-proof gasket 4.

The assembly steps of installing the first embodiment on the pipe member 8 and connecting the pipe plug 9 are described as follows:

First, the positioning tube portion 42 of the leak-proof gasket 4 is passed through the perforation 23 from the inner surface of one of the saddle straps 2 along the axis L, and the engagement ring groove 424 is engaged with one of the saddle straps 2 The inner flange 221, and the abutting curved surface 411 of the leakage preventing ring portion 41 abuts one of the inner surfaces of the saddle strap 2; Next, the gasket 53 is sleeved on the tube body 511 from the bottom side of the connection tube 51, and then the connection tube 51 and the gasket 53 are installed on the leak-proof gasket 4 together, and the gasket 53 is The clip is placed between the connecting tube 51 and one of the saddle straps 2. Next, the nut 52 is screwed to the connecting tube 51 from the direction of the inner surface of one of the saddle straps 2 so that the nut 52 abuts the shoulder 443 of the leak-proof washer 4 to make the leak-proof The washer 4 is assembled with one of the saddle straps 2. Next, one of the saddle strap 2, the leak-proof gasket 4 and the connecting pipe group 5 are installed together on the top side of the tube 8, and the other saddle strap 2 is butted into the bottom side of the tube 8 The saddle belt 2 is fixed to the saddle belt 2 through the fixing member groups 3 and clamped to the pipe member 8. At this time, the bottom plane 412 of the leak-proof gasket 4 is pressed and deformed by the locking force to be tight It is attached to the outer surface of the tube 8 to achieve a watertight effect. Finally, a drilling tool (not shown) is used to extend into the connecting pipe 51 along the axis L from the top side and an opening 81 is drilled on the top side of the pipe member 8 to make the through hole of the leak-proof gasket 4 43 Align the opening 81 of the pipe member 8, and then screw the pipe bolt 9 to the connecting external thread 513 of the connecting pipe 51 to complete the assembly.

With the new diverter device, the water in the pipe 8 can flow to the pipe plug 9, and at the same time, the inner flange 221 of the saddle belt 2 can be locked by using the snap ring groove 424 of the leak-proof gasket 4, and The abutting curved surface 411 of the leak-proof washer 4 abuts against the inner surface of one of the saddle straps 2, so that the present invention has the effect of being easy to assemble and having a better leak-proof effect. Therefore, it is indeed possible to achieve a new type of cost.
