[0019] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.
[0020] according to Figure 1-3 As shown, this embodiment proposes a pipe mouth connection device for processing a liquid reservoir, including a copper sleeve 1, a first sealing reinforcement component 2, a second sealing reinforcement component 3 and a limiting ring 4, one end of the copper sleeve 1 is connected to a butt joint 7 of a liquid reservoir 6 through a connecting piece 5, a limiting ring 4 is provided on the upper part of the copper sleeve 1, a first reinforcement groove 8 is symmetrically opened on the left and right outer walls of the lower end of the copper sleeve 1, a first sealing reinforcement component 2 is arranged in the first reinforcement groove 8, a second reinforcement groove 9 is symmetrically opened on the front and rear outer walls of the copper sleeve 1 above the first sealing reinforcement component 2, and a second sealing reinforcement component 3 is arranged in the second reinforcement groove 9;
[0021] The first sealing reinforcement component 2 and the second sealing reinforcement component 3 have the same structure, and both include a fixed plate 10, a driving member and an elastic reinforcement block 11.

Elastic reinforcement blocks 11 are movably provided inside the first reinforcement groove 8 and the second reinforcement groove 9, and the driving member is connected to the elastic reinforcement block 11. The shape of the inner wall of the elastic reinforcement block 11 is adapted to the shape of the outer wall of the docking pipe 7.
[0022] When the pipe mouth connecting device of the utility model is used to connect the connecting pipe with the docking pipe port 7 of the liquid reservoir 6, the copper sleeve 1 is first connected to the docking pipe port 7 by using the connecting piece. In order to improve the connection sealing between the copper sleeve 1 and the docking pipe port 7, the driving part of the first sealing reinforcement component 2 is first driven to move and squeeze the elastic reinforcement block 11 toward the outer wall of the docking pipe port 7, and then the driving part of the second sealing reinforcement component 3 is driven to move and squeeze the elastic reinforcement block 11 toward the outer wall of the docking pipe port 7, so as to improve the connection sealing between the copper sleeve 1 and the docking pipe port 7 from the upper and lower positions, and then the connecting pipe is inserted into the inside of the docking pipe port 7 from the upper end of the copper sleeve until the limiting ring 4 limits the insertion depth of the connecting pipe, and then the connecting pipe and the copper sleeve 1 are welded and fixed.
[0023] The driving member includes a driving bolt 12 and a bearing. The driving bolt 12 is threadedly connected to the middle of the fixing plate 10. One end of the driving bolt 12 is rotatably connected to one end of the elastic reinforcement block 11 through the bearing. The elastic reinforcement block 11 movably installed in the first reinforcement groove 8 and the second reinforcement groove 9 is driven to move by rotating the driving bolt 12.
[0024] The fixing plate 10 is threadedly connected with reinforcing bolts 13 at the four corners, and the elastic reinforcing block 11 is provided with threaded connection holes 14 adapted to the positions of the reinforcing bolts 13.

One end of the copper sleeve 1 is connected to the external thread on the outer wall of the connecting pipe port 7 through the internal threaded connecting sleeve, and the internal threaded connecting sleeve and the copper sleeve 1 are an integrally formed structure.
[0028] The length of the arc surface of the inner wall of the elastic reinforcement block 11 is greater than 1 / 4 of the length of the arc surface of the outer wall of the butt joint 7. There is a sealing reinforcement overlapping area in the vertical direction between the elastic reinforcement block 11 of the first sealing reinforcement component 2 and the elastic reinforcement block 11 of the second sealing reinforcement component 3 which are arranged up and down. The above arrangement can ensure the sealing between the copper sleeve 1 and the butt joint 7.
[0029] The utility model arranges a first sealing reinforcement component 2 in a first reinforcement groove 8 on the copper sleeve 1, and arranges a second sealing reinforcement component 3 in a second reinforcement groove 9. After the copper sleeve 1 is connected to the docking port 7, a driving member drives the elastic reinforcement block 11 to move and squeeze toward the outer wall of the docking port 7, so that the sealing between the copper sleeve 1 and the docking port 7 is effectively improved, and the connection stability between the copper sleeve 1 and the docking port 7 is effectively improved, thereby effectively improving the connection quality of the connecting pipe on the liquid reservoir 6 and improving the performance of the liquid reservoir 6.
