Therefore, the definition of "first" and "second" features can explicitly or implicitly include one or more of the features. In the description of the utility model, the meaning of "several" and "a number" is two or more, unless otherwise clearly and specifically defined.
[0022] The multifunctional three-way pipe connector of this embodiment includes a tubular body 1, a conversion member 2 and a fixing assembly 3. The tubular body 1 is provided with pipe interfaces 11 at both ends. The pipe interfaces 11 can be internal thread interfaces, external thread interfaces, flexible joints, or other common interface types.
[0023] A first conversion connection end 12 is provided in the middle of the tubular body 1, and a plurality of circles of first clamping edges 13 are provided on the outer circumference of the first conversion connection end 12. A positioning edge 14 is provided at the end of the first conversion connection end 12, which can be inserted into the conversion member 2, and the two are positioned; the conversion member 2 has multiple different types, and each conversion member 2 is provided with a second conversion connection end 21 at one end, and the second conversion connection end 21 can be connected to the first conversion connection end 12, and a plurality of circles of second clamping edges 22 are provided on the outer circumference of the second conversion connection end 21; and the other end of the conversion member 2 can be a small-diameter end 23, a large-diameter end 24, an equal-diameter end 25 or a bent end 26. Users can select a suitable type of conversion member for installation according to pipeline installation requirements, thereby obtaining three-way pipe fittings of different forms.
[0024] The fixing assembly 3 includes a sealing sleeve 31 and a locking sleeve 32. The sealing sleeve 31 is sleeved on the outside of the first conversion connection end 12 and the second conversion connection end 21. The sealing sleeve 31 is made of rubber material with a certain deformation ability. The inner diameter of the sealing sleeve 31 is the same as the outer diameter of the first conversion connection end 12 and the second conversion connection end 21 in an unstressed state. However, the outer diameters of the first clamping edge 13 and the second clamping edge 22 on the first conversion connection end 12 and the second conversion connection end 21 are slightly larger than the inner diameter of the sealing sleeve 31, which allows the first clamping edge and the second clamping edge to open the sealing sleeve, causing the sealing sleeve to deform and be clamped tighter.
[0025] The locking sleeve 32 is fixed on the outside of the sealing sleeve 31. The locking sleeve 32 includes a first locking piece 321 and a second locking piece 322 of a semi-cylindrical structure.

The sealing sleeve and the locking sleeve are positioned by the positioning rings to avoid misalignment and water leakage.
[0027] During installation, connect the pipe interfaces at both ends of the tubular body 1 to the main pipeline, and then select a suitable conversion piece 2 according to the design of the branch pipeline, first put the sealing sleeve 31 on the first conversion connection end 12, and then insert the second conversion connection end 21 of the conversion piece 2 into the sealing sleeve 31, adjust the position of the sealing sleeve 31 so that the sealing sleeve 31 is tightly clamped at the connection between the tubular body 1 and the conversion piece 2, and then put the locking sleeve 32 on the outside of the sealing sleeve 31 and fix it with fasteners.
[0028] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
