[0023] The present utility model will be further elaborated in detail below in conjunction with the accompanying drawings.

[0024] Refer to Figures 1 to 10 .

[0025] An installation structure of an oxygen chamber observation window includes a door body 1 and an observation window body 2 installed on the door body 1. The observation window body 2 is made of transparent glass. It also includes an installation frame body 3 and a rear pressing frame 4. Front and rear installation grooves are respectively formed on the inner and outer sides of the door body 1. The installation frame body 3 is inserted into the front installation groove, and a fixing groove 5 is formed on the rear side of the installation frame body 3. The observation window body 2 is placed in the fixing groove 5, and the rear pressing frame 4 is placed in the rear installation groove 9. A plurality of threaded connecting rods 6 are connected to the rear side of the installation frame body 3. Specifically, eight threaded connecting rods 6 are connected to the rear side of the installation frame body 3. The rear ends of the eight threaded connecting rods 6 all sequentially pass through the door body 1 and are threadedly connected with locking nuts 7 on the rear pressing frame 4. The observation window body 2 is pressed between the rear pressing frame 4 and the installation frame body 3.

[0026] In the installation of the observation window body 2 of the present utility model, the observation window body 2 is placed in the fixing groove 5, and then the installation frame body 3 and the rear pressing frame 4 are installed on the door body 1. Specifically, the installation frame body 3 is inserted into the front installation groove, the rear pressing frame 4 is placed in the rear installation groove 9, and the rear ends of the eight threaded connecting rods 6 all sequentially pass through the door body 1 and are threadedly connected with their respective locking nuts 7 on the rear pressing frame 4. At this time, the observation window body 2 is fixed between the rear pressing frame 4 and the installation frame body 3, and the observation window body 2 is completed for fixing. When disassembling, the locking nuts 7 are unscrewed, and then the installation frame body 3, the rear pressing frame 4 and the observation window body 2 are taken off. The present utility model does not need to apply sealant during the installation of the observation window body 2, and does not need to scrape off the sealant first when disassembling. Therefore, it is relatively convenient for the installation and disassembly of the observation window body 2.

[0027] In order to prevent the observation window body 2 from directly falling out of the installation frame body 3 during disassembly, a limiting device for limiting the observation window body 2 in the fixing groove 5 is further installed on the rear side of the installation frame body 3. Specifically, limiting devices are connected to the four corners on the rear side of the installation frame body 3. The limiting device includes a limiting knob 12 for limiting the observation window body 2 in the fixing groove 5. An outlet 11 for facilitating the entry and exit of the observation window body 2 in the fixing groove 5 is formed on the outer periphery of the limiting knob 12. Rotating grooves 13 corresponding to the four limiting devices are respectively formed on the four corners on the rear side of the installation frame body 3. The limiting knob 12 is rotatably connected in the rotating groove 13. Specifically, when the observation window body 2 is limited (refer to Figure 7 ), at this time, the outlet 11 of the limiting knob 12 is located in the rotating groove 13, and the limiting knob 12 limits the observation window body 2 between the limiting knob 12 and the installation frame body 3, and the observation window body 2 cannot be loosened from the fixing groove 5. When the observation window body 2 needs to be taken out of the fixing groove 5, at this time, the limiting knob 12 is rotated toFigure 8 At this position, the observation window body 2 can be taken out through this outlet 11.

[0028] Preferably, a first sealing ring 21 is connected between the door body 1 and the installation frame body 3 of the present utility model, and the sealing performance between the door body 1 and the installation frame body 3 is increased through the first sealing ring 21; a second sealing ring 22 is connected between the observation window body 2 and the installation frame body 3, and the second sealing ring 22 is located on the front side of the observation window body 2, and the sealing performance between the observation window body 2 and the installation frame body 3 is increased through the second sealing ring 22.
