In the prior art, conventional operating room gas terminal boxes usually use bolts to achieve the installation and fixation between the components, and require the assistance of tools such as screwdrivers to open them. It is difficult to quickly open the terminal box, and it is not very convenient to inspect and maintain the internal gas terminal. At the same time, when the conventional gas terminal box is working without an external gas pipe, the gas outlet end of the gas terminal is often directly exposed to the air, which is easily contaminated by dust, bacteria, etc., resulting in impurities and bacteria in the subsequently supplied gas. Therefore, an operating room gas terminal box with a quick-disassembly structure is proposed to solve the above-mentioned problems. Utility Model Content

When the knob is pushed to move the lock post toward the inside of the box body, the rear end of the lock post will fit with the inner wall of the third limiting hole and squeeze the connecting block against each other, causing the spring to compress until the rear end of the knob fits with the front end of the cover plate. Turning the knob drives the lock block fixed on the lock groove to rotate synchronously. At this time, the outer wall of the lock block will fit with the inner wall of the lock groove, limiting and fixing the lock post, thus achieving the locking between the cover plate and the box body. When the knob is turned again, the lock block will be disengaged from the inner wall of the lock groove, and the lock post will be ejected outwards under the elastic action of the spring, thus releasing the lock between the cover plate and the box body, solving the problem that conventional gas terminal boxes are difficult to open quickly and the internal gas terminal can be inspected.

[0015] 3. A rotating plate is hinged on the hinge seat. When the terminal box is not in use, the rotating plate can be rotated so that the dust cover can wrap and protect the air outlet of the gas terminal body from the outside, preventing external dust and bacteria from invading the interior of the gas terminal body, thus solving the problem that dust and bacteria can easily contaminate the air outlet of the gas terminal.
