Technical Field

[0001] The utility model relates to the technical field of tee joints, and particularly relates to a tee joint assembly. Background Art

[0002] A tee joint is a type of pipe fitting, generally used for connecting between three pipe ports, enabling single-branch diversion or multi-branch confluence connection of liquids or gases.

[0003] In the prior art, the most commonly used tee joint has a T-shaped appearance. The main body of this tee joint is T-shaped, and the three ends of the T are interconnected. With the cooperation of valves, the opening and closing of each port on the tee joint can be controlled, facilitating the control of liquid or solid transmission.

[0004] However, in the current T-shaped tee joint, the orientation of the port perpendicular to the other two pipe heads cannot be adjusted. After the tee joint is firmly installed between pipes, the laterally protruding pipe head on the tee joint cannot be adjusted. Generally, it needs to be debugged before installation, and subsequent changes are not possible. The whole assembly needs to be disassembled and reinstalled for re-debugging, resulting in inconvenient use and low adaptability of the tee joint. Therefore, a tee joint assembly is proposed herein.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0025] The present invention provides a Figures 1-5 tee joint assembly as shown, including a double-pass tube 100, a connecting sleeve 103, a sealing assembly and a positioning mechanism. A positioning ring groove 102 is provided on the side wall of the double-pass tube 100. A plurality of connecting holes 106 communicating with the inner cavity of the double-pass tube 100 are arranged at intervals in a circumferential array on the inner wall of the positioning ring groove 102. The connecting sleeve 103 is sleeved inside the positioning ring groove 102. A connecting pipe head 104 communicating with the positioning ring groove 102 is fixedly connected to the outer wall of the connecting sleeve 103. The sealing assembly is arranged between the connecting sleeve 103 and the positioning ring groove 102, and the sealing assembly is used for sealing between the connecting sleeve 103 and the double-pass tube 100. The positioning mechanism is arranged between the connecting sleeve 103 and the double-pass tube 100, and the positioning mechanism is used for positioning the direction of the connecting pipe head 104. The connecting sleeve 103 can rotate in the positioning ring groove 102 on the outer wall of the double-pass tube 100. At the same time, in cooperation with the sealing assembly, the connecting holes 106 can be sealed, so that the connecting pipe head 104 rotates with the rotation of the connecting sleeve 103 for steering. It is possible to separately adjust the direction of the connecting pipe head 104 on the premise that the double-pass tube 100 has been installed, so that the connecting pipe head 104 can meet the connection of pipes in different directions on the same horizontal plane, thereby improving the adaptability of the tee joint assembly in use. At the same time, in cooperation with the positioning mechanism, the position can be locked after the direction of the connecting pipe head 104 is adjusted, so that the connecting pipe head 104 can maintain the stability of the connection between the double-pass tube 100 and the external pipe.

[0026] In a preferred embodiment, the sealing assembly includes a sealing ring 105, a sealing ring groove 101 matching the sealing ring 105 is opened in the middle of the inner side of the positioning ring groove 102, the sealing ring groove 101 is connected to the connecting hole 106, and the sealing ring 105 is fixedly connected to the middle of the inner side of the connecting sleeve 103; the connecting sleeve 103 and the positioning ring groove 102 are both provided with an assembly ring groove 107 at the top and bottom positions on the opposite side, and an O-ring 108 is provided at the inner position of the assembly ring groove 107 between the connecting sleeve 103 and the positioning ring groove 102. The sealing ring 105 on the inner side of the connecting sleeve 103 and the two-way pipe 100 are connected. The sealing ring groove 101 is adapted so that the connecting sleeve 103 can rotate on the two-way tube 100 while ensuring the sealing between the connecting sleeve 103 and the multiple connecting holes 106, so that the inner cavity of the two-way tube 100 can only be connected to the connecting pipe head 104 through the connecting holes 106 at the corresponding positions; in addition, by positioning the inner wall of the ring groove 102 and the inner wall of the connecting sleeve 103, an O-ring 108 can be assembled between the two-way tube 100 and the connecting sleeve 103 for sealing, thereby enhancing the sealing between the connecting sleeve 103 and the two-way tube 100.

[0027] Furthermore, the positioning mechanism includes a positioning plate 200 and a locking plate 201, the positioning plate 200 is fixedly connected to the outer wall of the connecting sleeve 103, the locking plate 201 is fixedly connected to the outer wall of the two-way tube 100, and a locking mechanism is provided between the positioning plate 200 and the locking plate 201; the locking mechanism includes a limiting screw 203, the bottom of the limiting screw 203 is rotatably connected to the side wall of the positioning plate 200, the end of the limiting screw 203 away from the positioning plate 200 is threadedly connected with a positioning nut 204, and the side wall of the locking plate 201 is provided with a limiting card groove 202 matching the limiting screw 203; there are multiple limiting card grooves 202 located at the side wall position of the locking plate 201, and the multiple limiting card grooves 202 are arranged in a ring array at intervals, and the multiple limiting card grooves 202 respectively correspond to the positions of the multiple connecting holes 106; in this embodiment, when the positioning plate 200 rotates with the connecting sleeve 103 When the locking plate 201 is in the locked position, the limit screw 203 on the positioning plate 200 corresponds to the position of the limit slot 202 of the locking plate 201. At this time, it is only necessary to manually lift the limit screw 203 so that the limit screw 203 can rotate upward around the connection with the positioning plate 200, so that the outer wall of the limit screw 203 is inserted into the limit slot 202 at the corresponding position on the locking plate 201, and then manually rotate the positioning nut 204 so that the positioning nut 204 can move downward while rotating on the limit screw 203 until the bottom end of the positioning nut 204 is in contact with the top end of the locking plate 201 and is squeezed, which can lock the limit screw 203 and the locking plate 201, so that the limit screw 203 cannot be detached from the locking plate 201, so as to achieve the fixation of the position between the connecting pipe head 104 and the two-way pipe 100, so as to ensure the stability of the three-way joint assembly during use.
