[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] In its specific implementation, such as Figures 1-4 The present invention provides a technical solution: a pipe fitting joint device for a ventilation duct, including a duct 1, and further including a connecting component 3, the connecting component 3 including a connecting cavity 301, the outer wall of the connecting cavity 301 being provided with a plurality of ball joint seats 302; The connecting component 2 includes a connecting pipe 205, one end of which is provided with a ball joint head 208, and the air duct 1 is sleeved on the outer wall of the connecting pipe 205, and the ball joint head 208 is connected to the connecting cavity 301 through the ball joint seat 302. It also includes: threaded seat 207, which is installed on the outer wall of connecting pipe 205; Threaded sleeve 204 is threadedly connected to threaded seat 207, and threaded sleeve 204 is fitted on the outer wall of air duct 1. It also includes: an extrusion block 206, which is disposed on the outer wall of the connecting pipe 205, and there are multiple extrusion blocks 206, and one end of the extrusion block 206 is provided with an inclined surface; The sealing ring 201 is sleeved on the outer wall of the connecting pipe 205, and the sealing ring 201 is located on one side of the extrusion block 206, and one side of the sealing ring 201 is provided with an inclined surface corresponding to the extrusion block 206. It also includes: a pull rod 202, one end of which is fixedly connected to the sealing ring 201, and the pull rod 202 is located in the gap between the extrusion blocks 206; The connecting ring 203 is installed at one end of the pull rod 202. By rotating the threaded sleeve 204, the air duct 1 can be moved, and the connecting ring 203 can be moved, thereby moving the sealing ring 201 and causing the sealing ring 201 to be inserted between the extrusion block 206 and the air duct 1.

[0021] Specifically, when connecting the air duct 1, the ball joint head 208 can be rotated within the ball joint seat 302 by rotating the connecting pipe 205, so that the connecting pipe 205 can be aligned with the air duct 1. Then, the air duct 1 is inserted into the outer wall of the connecting pipe 205, and one end of the air duct 1 contacts the connecting ring 203. Then, the threaded sleeve 204 slides from the outer wall of the air duct 1 to one end, and the threaded sleeve 204 is connected to the threaded seat 207. As the threaded sleeve 204 gradually goes deeper, it can drive the air duct 1 to move and push the connecting ring 203 to move. As the connecting ring 203 moves, it can drive the sealing ring 201 to move, so that the sealing ring 201 can gradually move between the extrusion block 206 and the air duct 1, thereby sealing the air duct 1. like Figure 4 As shown, the connecting component 3 also includes: a sealing gasket 303, which is disposed on the inner wall of the ball joint seat 302, and the inner side of the sealing gasket 303 is in contact with the ball joint head 208; It also includes: a shrink block 304, which is installed on one side of the ball joint seat 302, and multiple shrink blocks 304 are arranged around it; It also includes: a clamping ring 305, which connects the shrink blocks 304 together through the through holes provided inside the shrink blocks 304. The clamping ring 305 tightens the shrink blocks 304, which can clamp the sealing gasket 303 and the ball joint head 208. Specifically, after adjusting the connecting pipe 205, the shrink block 304 can be pulled by the fastening ring 305 to shrink, thereby squeezing the ball joint head 208 and the sealing gasket 303 through the shrink block 304, thus ensuring the sealing between the ball joint head 208 and the ball joint seat 302.

[0022] Working principle: When connecting the air duct 1, the ball joint head 208 can be rotated within the ball joint seat 302 by rotating the connecting pipe 205, so that the connecting pipe 205 can be aligned with the air duct 1. Then, the air duct 1 is inserted into the outer wall of the connecting pipe 205, with one end of the air duct 1 in contact with the connecting ring 203. Then, the threaded sleeve 204 slides from the outer wall of the air duct 1 to one end, and the threaded sleeve 204 is connected to the threaded seat 207. As the threaded sleeve 204 gradually goes deeper, it can drive the air duct 1 to move, which can push the connecting ring 203 to move. As the connecting ring 203 moves, it can drive the sealing ring 201 to move, so that the sealing ring 201 can gradually move between the extrusion block 206 and the air duct 1. After adjusting the connecting pipe 205, the shrink block 304 can be pulled by tightening the clamping ring 305 to shrink, which can squeeze the ball joint head 208 and the sealing gasket 303 through the shrink block 304.
