[0025] First, multiple groups of stepped bosses 301 are fixedly connected to the outer side of the plug 3, a first sealing ring 302 is sleeved on the rear end of the plug 3, and a sealing gasket 303 is sleeved on the rear end of the fixed sleeve 5 and on the outer side of the oxygen inlet pipe 2. When installing the display meter 1, the plug 3 is inserted into the oxygen outlet of the oxygen therapy device until the positioning ring 4 abuts against the outer side of the oxygen outlet. The multiple groups of stepped bosses 301 can improve the tightness of the insertion of the plug 3, and the first sealing ring 302 is used to seal the oxygen outlet and the plug 3. The interior of the fixed sleeve 5 is provided with an internal thread, and the outer side of the oxygen outlet of the oxygen therapy device is provided with an external thread adapted to the fixed sleeve 5. Tightening the fixed sleeve 5 can fix the plug 3, and the sealing gasket 303 can ensure the sealing of the fixed sleeve 5, so that the display meter 1 can be quickly installed on the oxygen therapy device. The display meter 1 has dials showing the oxygen flow rate and concentration respectively, so that the oxygen flow rate and concentration can be monitored. At the same time, the oxygen flow rate and concentration can be adjusted respectively by two groups of adjustment knobs on the outer side of the display meter 1, thereby greatly improving the convenience of installation operation.

[0026] Then, the outer side of the quick connector 7 is slidably connected with a movable sleeve 701, the outer side of the quick connector 7 and the inner sleeve of the movable sleeve 701 are provided with a first spring 702, the inner side of the quick connector 7 is movably provided with multiple sets of clamping balls 703, the front end of the movable sleeve 701 is provided with a movable groove 704, the outer side of the connector 8 is provided with an annular clamping groove 705 adapted for use with the clamping ball 703, the outer side of the movable sleeve 701 is provided with an anti-slip groove 706, the rear end of the first spring 702 is fixedly connected to the inner side wall of the quick connector 7, and the front end of the first spring 702 is fixedly connected to the movable sleeve 7 01's internal fixed connection will be displayed. After installation of Table 1, first slide the movable sleeve 701 outside the quick connector 7, and then insert the connector 8 into the interior of the quick connector 7. When the connector 8 is inserted, the multiple sets of snap balls 703 will first squeeze into the interior of the movable groove 704. After the connector 8 is fully inserted, release the movable sleeve 701, so that the first spring 702 pushes the movable sleeve 701 to snap the multiple sets of snap balls 703 into the interior of the annular snap groove 705, thereby quickly connecting the connector 8 and the quick connector 7, thereby facilitating the use of oxygen delivery and further improving the convenience of use.

[0027] Secondly, a second sealing ring 707 is provided on the outside of the quick connector 7 and at the rear end of the movable sleeve 701, and a third sealing ring 708 is provided on the front end of the outside of the quick connector 7. The second sealing ring 707 and the third sealing ring 708 can ensure the sealing of both ends of the movable sleeve 701.

[0028] Finally, a movable block 709 is slidably connected inside the quick connector 7, and the rear end of the movable block 709 is fixedly connected to the quick connector 7 by a second spring 710. Oxygen supply channels 711 are provided at the upper and lower ends inside the quick connector 7, and an oxygen supply through hole 712 is provided at a position corresponding to the oxygen supply channel 711 on the outside of the connector 8. The movable block 709 is slidably connected to the quick connector 7 through a limiting groove 713, and a sealing sleeve 714 is provided at the front end of the movable block 709. When the connector 8 is not inserted into the quick connector 7, the second spring 710 pushes the movable block 709 against the right end of the limiting groove 713, thereby closing the oxygen supply channel 711 to prevent oxygen leakage. After the connector 8 is inserted into the quick connector 7, the connector 8 presses against the movable block 709 to the left to connect the oxygen supply through hole 712 with the oxygen supply channel 711, thereby further improving the convenience of use for rapid oxygen supply.

[0029] In this embodiment, the implementation scenario is specifically as follows: when installing the display meter 1, the plug 3 is inserted into the oxygen outlet of the oxygen therapy device until the positioning ring 4 is against the outside of the oxygen outlet. The tightness of the insertion of the plug 3 can be improved by using multiple groups of stepped bosses 301. At the same time, the oxygen outlet and the plug 3 are sealed by using the first sealing ring 302. The interior of the fixing sleeve 5 is provided with an internal thread, and the outer side of the oxygen outlet of the oxygen therapy device is provided with an external thread adapted to the fixing sleeve 5. Tightening the fixing sleeve 5 can fix the plug 3. At the same time, the sealing gasket 303 can ensure the sealing of the fixing sleeve 5, so that the display meter 1 can be quickly installed on the oxygen therapy device to monitor the oxygen flow rate and concentration. After the display meter 1 is installed, it will slide first. The movable sleeve 701 on the outside of the quick connector 7 is then inserted into the interior of the quick connector 7. When the connector 8 is inserted, the multiple sets of locking balls 703 will first squeeze into the interior of the movable groove 704. After the connector 8 is fully inserted, the movable sleeve 701 is released, so that the first spring 702 pushes the movable sleeve 701 to lock the multiple sets of locking balls 703 into the interior of the annular locking groove 705, thereby quickly connecting the connector 8 to the quick connector 7. After the connector 8 is inserted into the interior of the quick connector 7, the connector 8 presses the movable block 709 to the left to connect the oxygen supply through hole 712 and the oxygen supply channel 711, thereby quickly supplying oxygen. The entire operation process is simple and convenient. The present invention can improve the convenience of installation operation and the convenience of use through design.
