[0021] Example

[0022] See also Figures 1 to 4 In an embodiment of the utility model, a novel oxygen sensor plug-in assembly structure includes a base 1, a mounting plate 10 is arranged at the right end of the base 1, an oxygen sensor body is arranged on the mounting plate 10, and a plurality of through holes 9 are evenly arranged on the base 1. Through the action of the through holes 9, air can enter the interior of the base 1, so that the oxygen sensor body can detect oxygen in the gas, so that the oxygen sensor body can perform corresponding work.

[0023] The base 1 is also provided with a mounting frame 6, on which a cleaning plate 8 is slidably provided, and the cleaning plate 8 contacts the outer wall of the base 1. At this time, the cleaning plate 8 can be rotated to clean the impurities remaining on the through hole 9, thereby ensuring the cleaning quality of the cleaning plate 8 for the base 1, thereby ensuring the use efficiency of the through hole 9, and thereby ensuring the use efficiency of the aerobic sensor body. A motor 3 is also provided on the left side of the base 1 through a fixing plate 2. The power output shaft of the motor 3 passes through the left side plate wall of the base 1 and is rotatably connected with the plate wall. A gear 4 is provided on the power output shaft of the motor 3 through a key connection, and a gear ring 5 is sleeved on the outer side of the gear 4. The gear 4 can be used to drive the gear ring 5 to rotate through the motor 3. A connecting block 7 is provided on the side wall of the gear ring 5, and the end of the connecting block 7 is connected to the cleaning plate 8. At this time, under the action of the gear ring 5, the cleaning plate 8 can be driven to rotate on the base 1, so that the cleaning plate 8 cleans the outer shell of the base 1, thereby ensuring the use efficiency of the device, and thereby better ensuring the use efficiency of the aerobic sensor body.

[0024] A support plate 13 is further provided on the side wall of the mounting plate 10, and a block 14 is slidably provided on the support plate 13. A slot 16 used in conjunction with the block 14 is provided on the side wall of the base 1. When the base 1 is connected to the mounting plate 10, the aerobic sensor body can be better fixed on the base 1 under the action of the block 14 and the slot 16, thereby ensuring the use efficiency of the aerobic sensor body. A first spring 15 is also provided on the support plate 13, and the other end of the first spring 15 is connected to the block 14. Under the action of the first spring 15, the connection quality of the block 14 and the slot 16 is guaranteed, thereby ensuring the connection quality of the mounting plate 10 and the base 1, thereby ensuring the installation quality of the aerobic sensor body, so that the aerobic sensor body can better perform detection work.

[0025] A plurality of cavities are evenly arranged inside the mounting plate 10, in which a slide plate 11 is slidably arranged, a plug rod 12 is arranged on the side wall of the slide plate 11, and a socket for use with the plug rod 12 is arranged on the card block 14. Under the action of the plug rod 12 and the socket, the connection quality between the card block 14 and the card slot 16 is guaranteed.

[0026] A support rod 17 is also provided on the outer wall of the slide plate 11. The support rod 17 passes through the mounting plate 10 and is slidably connected to the mounting plate 10. A handle 1701 is also provided at the outer end of the support rod 17. By pulling the handle 1701, the slide plate 11 can be driven to move through the support rod 17, so that the insertion rod 12 releases the restriction on the block 14, which makes it convenient for the staff to remove the aerobic sensor body. A second spring 18 is also sleeved on the outer side of the support rod 17. One end of the second spring 18 is connected to the slide plate 11, and the other end of the second spring 18 is connected to the mounting plate 10. Under the action of the second spring 18, the fixing quality of the insertion rod 12 to the block 14 is guaranteed.

[0027] In actual use, when the aerobic sensor body needs to be installed, the staff will use the handle 1701 to drive the slide plate 11 to move through the support rod 17, so that the insertion rod 12 releases the restriction on the block 14. At this time, the block 14 can be lifted, and then the mounting plate 10 is aligned with the base 1 for installation. When the block 14 is aligned with the slot 16, the block 14 is released so that the first spring 15 drives the block 14 to move, so that the block 14 is inserted into the slot 16, and the handle 1701 is released under the action of the second spring 18, so that the insertion rod 1 2 is inserted into the insertion hole on the card block 14, thereby completing the installation of the aerobic sensor body. When the aerobic sensor body is in use, the gas enters the base 1 through the through hole 9. At this time, the aerobic sensor body can contact with the air, so that the aerobic sensor body can work accordingly. At the same time, the motor 3 can be started to use the gear 4 and the gear ring 5 to drive the cleaning plate 8 to move, so that the cleaning plate 8 cleans the impurities on the through hole 9, thereby ensuring the use efficiency of the through hole 9, thereby ensuring the use efficiency of the aerobic sensor body.
