For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] Example 1:

[0025] Please see Figure 1-4 This utility model provides a technical solution: a quick connection accessory for oxygen delivery pipeline of a centralized oxygen production station, including a support frame 1, a connecting pipe 2 fixedly installed on the top of the support frame 1, delivery pipes 3 at both ends of the connecting pipe 2, a connecting mechanism 4 on the outside of the delivery pipe 3, and an anti-accidental contact mechanism 5 on the outside of the delivery pipe 3.

[0026] Furthermore, the connecting mechanism 4 includes a tube 41, which is fixedly installed at one end of the delivery tube 3 near the connecting tube 2. A sealing ring 42 is fixedly installed on the inner side of the tube 41, and a sealing ring 43 is fixedly installed on the outer side of the delivery tube 3. Two fastening blocks 44 are fixedly installed on the outer side of each of the two delivery tubes 3. Four mounting blocks 45 are fixedly installed on the outer side of the connecting tube 2. A control block 46 is movably installed on the outer side of the mounting block 45. A retaining ring 47 is rotatably installed inside the control block 46. The retaining ring 47 is locked onto the outer side of the fastening block 44, thereby completing the installation of the delivery tube 3 and the connecting tube 2.

[0027] Furthermore, the retaining ring 47 is snapped onto the outside of the retaining block 44, and the sealing ring 43 is set between the connecting pipe 2 and the conveying pipe 3, which makes the installation of the connecting pipe 2 and the conveying pipe 3 more airtight and avoids the problem of oxygen leakage.

[0028] Furthermore, the insertion tube 41 is slidably installed inside the connecting tube 2, and the sealing ring 42 is set between the insertion tube 41 and the connecting tube 2. Two limiting blocks are fixedly installed on the outside of the insertion tube 41, and the limiting blocks are inserted into the inside of the connecting tube 2. The limiting blocks are aligned with the limiting grooves in the connecting tube 2 for positioning and insertion, so that the buckle 44 and the mounting block 45 correspond in position, which facilitates subsequent installation.

[0029] Example 2:

[0030] Please see Figure 5 Furthermore, in conjunction with Embodiment 1, it is further found that the anti-accidental contact mechanism 5 includes four arc-shaped rubber strips 51, all four arc-shaped rubber strips 51 are fixedly installed inside the support frame 1, and two anti-detachment rings 52 are fixedly installed on the outside of the two conveying pipes 3. A protective cover 53 is provided on the outside of the conveying pipes 3 to protect the installation of the buckle block 44 and its connected mechanism, thereby avoiding the problem of oxygen leakage caused by accidental contact and making it safer.

[0031] Furthermore, the protective cover 53 is positioned between the two anti-detachment rings 52 and is inserted between the two arc-shaped rubber strips 51, thus preventing the protective cover 53 from falling off the outside of the delivery pipe 3.

[0032] In actual operation, when this device is used, the moving conveying pipe 3 inserts the insertion tube 41 into the connecting pipe 2. Two limiting blocks are fixedly installed on the outside of the insertion tube 41. The limiting blocks are aligned with the limiting grooves inside the connecting pipe 2 for positioning and insertion, so that the buckle block 44 corresponds to the position of the mounting block 45, which facilitates subsequent installation. The conveying pipe 3 drives the insertion tube 41 to move until the side of the sealing ring 43 away from the insertion tube 41 contacts the connecting pipe 2. Then, the control block 46 is lifted to hang the buckle ring 47 on the outside of the buckle block 44. Then, the control block 46 is pressed down to reset, so that the buckle ring 47 is locked on the outside of the buckle block 44, thus completing the installation of the conveying pipe 3 and the connecting pipe 2. The other side is the same, which makes the installation of the conveying pipe 3 and the connecting pipe 2 more stable. Moreover, the installation of the buckle ring 47 and the buckle block 44 is relatively quick, so that the installation of the connecting pipe 2 does not require the use of additional tools. The operation is simple and efficient. Both the 4 and the mounting block 45 are bolted to the outside of the conveying pipe 3 and the connecting pipe 2, avoiding the problem of parts falling off during installation and disassembly. At this time, the sealing ring 2 43 is pressed between the conveying pipe 3 and the connecting pipe 2, and the sealing ring 1 42 is pressed between the insertion tube 41 and the connecting pipe 2, making the installation of the connecting pipe 2 and the conveying pipe 3 more airtight and avoiding the problem of oxygen leakage. After the conveying pipe 3 and the connecting pipe 2 are installed, the movable protective cover 53 slides on the outside of the conveying pipe 3 close to the support frame 1, so that the protective cover 53 is inserted into the inside of the two arc-shaped rubber strips 51, so that the position of the protective cover 53 is fixed, thereby protecting the installation of the buckle block 44 and its connected mechanism, avoiding the problem of oxygen leakage caused by accidental contact, and making it safer. The two anti-detachment rings 52 prevent the protective cover 53 from falling off the outside of the conveying pipe 3. The installation of the other conveying pipe 3 and the connecting pipe 2 is the same.
