Description

Technical Field

[0001] The utility model relates to the technical field of pipe fittings, in particular to a three-way joint which can rotate after being inflated. Background Art

[0002] A known three-way joint is a kind of pipe joint used to connect three different pipes to allow the three pipes to communicate. Existing three-way joints are mostly cast in one piece, and the joint cannot be rotated or replaced. When the joint part is damaged, the existing joint needs to be completely replaced, which is very wasteful. For example, a Chinese utility model patent with authorization announcement number CN204879209U discloses a three-way joint that can rotate at multiple angles, including a base, a first groove and a second groove are provided in the base, and a first through hole is provided on the second groove; a first internal thread is provided in the first through hole, and a first connector is installed in the second groove, the first connector includes a fixed seat and a threaded connector, the threaded connector is screwed to the first internal thread, and the threaded connector extends outside the base; the fixed seat is clamped with the second groove, and a sealing ring is also installed in the second groove, and the sealing ring is placed on the first connector. In this structure, movable connectors are installed on the first connection end and the second connection end, which can rotate at multiple angles, wherein the first connector includes a fixed seat and a threaded connector, the threaded connector is screwed to the first internal thread, and the threaded connector extends outside the base. Although the threaded connector in the first connector can rotate, the sealing is poor and sometimes there is a leakage problem, so it cannot meet the use requirements, so it is necessary to make improvements based on this defect.

[0025] Example 1: See Figure 1 and Figure 2 A three-way joint that can be rotated after inflation includes a three-way main body 1 and a first joint 11, a second joint 12 and a third joint 13 arranged on the three-way main body 1. The third joint 13 is provided with an air pipe 2, and a rotating component 3 and a sealing component 4 are provided between the air pipe 2 and the third joint 13. The air pipe 2 can be rotated 360 degrees through the rotating component 3 after being connected, and has good sealing performance through the sealing component 4, which effectively solves the leakage problem and is more conducive to meeting the use requirements.

[0026] Embodiment 2: It can be explained on the basis of embodiment 1, such as Figure 1 As shown in FIG. 2 , the rotating assembly 3 includes an inner groove 31 arranged on the inner wall of the third joint 13 and an outer groove 32 arranged on the outer wall of the trachea 2. Steel balls 33 are installed in the inner groove 31 and the outer groove 32 corresponding to each other. The steel balls 33 can realize 360° rotation, and the arrangement is simple, which is also convenient for production and installation.

[0027] Embodiment 3: It can be described on the basis of Embodiment 1 or Embodiment 2, such as Figure 1 As shown in FIG. 2 , the sealing assembly 4 includes at least one groove 41 provided on the outer wall of the trachea 2, and a sealing ring 42 is installed in each groove 41, which is conducive to improving the sealing performance between the trachea 2 and the inner wall of the third joint 13. It should be noted that the sealing ring 42 is made of rubber material, which is convenient for production and manufacturing. In this embodiment, two grooves 41 are used, and a sealing ring 42 is installed in each groove 41, which greatly improves the sealing performance.

[0028] like Figure 1 As shown in Figure 2, after the air pipe 2 in the utility model is connected to the air, due to the expansion of the air in the air pipe 2, the air pipe 2 is sealed and fixedly connected to the third joint 13 through the sealing component 3, which is also beneficial for the air pipe 2 to rotate through the rotating component 3, which not only greatly improves the sealing performance and avoids the occurrence of leakage problems, but also helps to meet the use requirements of adjustment.

[0029] Embodiment 4: It can be described on the basis of Embodiment 1, Embodiment 2 or Embodiment 3, such as Figure 1As shown in Figure 2, the trachea 2 includes an inner tube portion 21 arranged inside the third joint 13, a middle tube portion 22 is arranged on the inner tube portion 21, the middle tube portion 22 is connected to the outer tube portion 23, and the middle tube portion 22 is located on the end face of the third joint 13, which is conducive to the rapid installation of the inner tube portion 21. The diameter of the middle tube portion 22 is larger than the diameter of the inner tube portion 21, and the diameter of the middle tube portion 22 is larger than the diameter of the outer tube portion 23. The inner tube portion 21, the middle tube portion 22 and the outer tube portion 23 are integrally formed, which greatly improves the firmness of the structure and has better sealing performance.
