[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figure 1 and Figure 2 As shown, the utility model provides a technical solution for a variable diameter oblique pipe joint, including a joint body 1, a main pipe interface 2 is provided at one end of the joint body 1, and a branch pipe interface 3 is provided at the other end of the joint body 1, and a sealing mechanism 4 is connected to the branch pipe interface 3. The sealing mechanism 4 includes a connecting sleeve 401 fixedly installed on the branch pipe interface 3, and a rubber hollow sealing ring 402 is fixedly installed in the connecting sleeve 401. A positioning mechanism 5 is provided on the connecting sleeve 401. By cooperating with the positioning mechanism 5 and the sealing mechanism 4, branch pipes of different diameters can be connected to the main pipe, which is convenient for users to install.

[0022] like Figure 2 and Figure 3 As shown, the sealing mechanism 4 includes a connecting sleeve 401 fixedly mounted on the branch pipe interface 3, a rubber hollow sealing ring 402 fixedly mounted in the connecting sleeve 401, an exhaust pipe port 403 and an air inlet pipe port 404 fixedly mounted on the rubber hollow sealing ring 402, a one-way valve 405 is provided in the air inlet pipe port 404, a sealing end cover 406 is provided on the exhaust pipe port 403, an inlet and outlet notch 407 is opened on the connecting sleeve 401, and the exhaust pipe port 403 and the air inlet pipe port 404 both extend out of the connecting sleeve 401 through the inlet and outlet notch 407.

[0023] Specifically, branch pipes of different diameters can be inserted into the connecting sleeve 401. After the branch pipe is inserted into the connecting sleeve 401, air can be inflated into the rubber hollow sealing ring 402 through the air inlet pipe port 404, and the rubber hollow sealing ring 402 is used to expand. After the rubber hollow sealing ring 402 expands, the branch pipe will be sealed in the connecting sleeve 401 to ensure the sealing performance of the joint body 1.

[0024] like Figure 2 and Figure 4 As shown, the positioning mechanism 5 includes a positioning threaded sleeve 501 fixedly mounted on the connecting sleeve 401, a limiting screw 502 is installed on the internal thread of the positioning threaded sleeve 501, a slot 505 is provided at one end of the limiting screw 502, and a cutting blade 503 is provided at the edge of the other end of the limiting screw 502, an annular glue bag 504 is preset in the connecting sleeve 401, a positioning through hole 507 is provided on the connecting sleeve 401, and the positioning threaded sleeve 501 is installed on the connecting sleeve 401 through the positioning through hole 507.

[0025] Specifically, a screwdriver can be used to rotate the limiting screw 502, causing it to move forward and come into contact with the branch pipe, thereby fixing the connector body 1 on the branch pipe. When the limiting screw 502 moves forward, the cutting blade 503 will cut the annular glue bag 504, causing the glue inside it to flow out and fill the connecting sleeve 401, further improving the sealing performance of the connector body 1.

[0026] Working principle: When in use, the connector body 1 is fixed to the main pipe using the main pipe interface 2. After the connector body 1 is fixed to the main pipe, branch pipes of different diameters can be inserted into the connecting sleeve 401. After the branch pipes of different diameters are inserted into the connecting sleeve 401, air can be inflated into the rubber hollow sealing ring 402 through the air inlet pipe port 404. The rubber hollow sealing ring 402 is used to expand. After the rubber hollow sealing ring 402 expands, the branch pipe will be sealed in the connecting sleeve 401. At the same time, the user can loosen the sealing end cover 406. After loosening the sealing end cover 406, the gas in the rubber hollow sealing ring 402 will be discharged. After the gas in the rubber hollow sealing ring 402 is discharged, it will shrink, which is convenient for the user to adjust the branch pipe in the connecting sleeve 4 01, after the branch pipe is sealed in the connecting sleeve 401, the screwdriver can be connected to the slot 505. After the screwdriver is connected to the slot 505, the limiting screw 502 can be rotated. After rotating the limiting screw 502, it will move forward and abut against the branch pipe, so that the connector body 1 remains fixed on the branch pipe. Since the limiting screw 502 is installed on the connecting sleeve 401 through the positioning thread sleeve 501, and the limiting screw 502 is aligned front to back with the annular glue bag 504, the cutting blade 503 will cut the annular glue bag 504 when the limiting screw 502 moves forward. After the annular glue bag 504 is cut, the glue inside it will be filled into the connecting sleeve 401, further improving the sealing performance of the connector body 1.

[0027] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
