[0002] In the pneumatic system, the air pipe joint is an important connecting component, and its sealing performance directly affects the stability and working efficiency of the entire system; the air pipe joint has different structural characteristics according to the use requirements. Figure 1 , Figure 2 The utility model discloses an existing trachea joint, the end of which is converged inwards to facilitate clamping and fixing the male head, and a sealing ring 1 is arranged at the bottom of the trachea female head, and the diameter of the sealing ring is larger than the diameter of the end of the trachea female head. This design makes it very inconvenient to install the sealing ring. The current method is to compress the sealing ring to a smaller size first, and then insert it into the trachea joint, and then allow it to expand after the sealing ring is fully inserted. Although this method solves the problem of installation difficulties to a certain extent, it still has some shortcomings; firstly, during the compression and insertion process, the sealing ring is easily deformed or damaged, affecting the sealing effect; secondly, this process adopts manual operation with low production efficiency, and if the operation is improper, it may cause a gap between the sealing ring and the trachea joint, thereby affecting the sealing performance.

[0016] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0017] Reference Figure 3 The utility model provides a trachea joint sealing ring installation mechanism, including a base 2, on which a mounting seat 3, a sliding seat 4 and a curved arm support 5 are installed. A socket 301 matching the trachea joint is provided at the center of the mounting seat 3. The sliding seat 4 is located on one side of the mounting seat 3 and is fixedly connected to the base 2. The curved arm support 5 is located on the other side of the sliding seat 4, connected to the base 2 and used to support the curved arm 8.

[0018] A telescopic tube 6 is slidably installed on the sliding seat 4, and a circular ring 602 coaxial with the socket 301 is provided on one end of the telescopic tube 6 adjacent to the mounting seat 3. In actual applications, the inner diameter of the circular ring 602 is larger than the outer diameter of the trachea joint. A cutting bolt 603 is provided along its radial direction, and the cutting bolt 603 is threadedly matched with the circular ring 602. The lower end of the cutting bolt 603 is conical, and the distance between the lower end of the cutting bolt 603 and the circular ring 602 can be adjusted to adapt to trachea joints of different diameters. During operation, the circular ring 602 approaches the trachea joint installed on the mounting seat 3, and the lower end of the cutting bolt 603 is inserted into the clamping flap gap of the trachea joint. Since its end is converged inwardly, as the circular ring 602 approaches the mounting seat 3, the cone at the lower end of the cutting bolt 603 gradually penetrates into the clamping flap gap of the trachea joint, thereby opening the end of the trachea joint. In practical applications, in order to prevent the cutting bolts 603 from excessively stretching the air pipe joint and causing damage to the product, a limiting mechanism can be installed on the base 2 to limit the forward travel of the ring 602.

[0019] A loading column 7 is installed inside the telescopic tube 6. The length of the loading column 7 is greater than that of the telescopic tube 6. A boss is provided on one end of the loading column 7 adjacent to the mounting seat 3. The boss is used to install the sealing ring 1. When working, the sealing ring is placed on the boss. After the end of the trachea joint is stretched open, the sealing ring is pushed to the installation position inside the trachea joint as the loading column 7 moves. The outer ring of the sealing ring is tightly matched with the inner wall of the trachea joint. After the loading column 7 retracts, the sealing ring is installed in place.

[0020] A crank arm 8 is installed on the crank arm support 5, and the horizontal section of the crank arm 8 is rotatably arranged on the crank arm support 5. The first arc plate 801 and the second arc plate 802 are alternately installed on the horizontal section of the crank arm 8. The arc surface of the first arc plate 801 is opposite to the telescopic tube 6, and the arc surface of the second arc plate 802 is opposite to the loading column 7. When the crank arm 8 rotates, the first arc plate 801 first contacts the telescopic tube 6 and pushes it to move toward the mounting seat 3 to open the end of the air pipe joint. Then, the second arc plate 802 contacts the loading column 7 and pushes it to move toward the mounting seat 3 to install the sealing ring 1 in the telescopic tube 6.

[0021] In practical applications, the above structure can be replaced by a propulsion mechanism that achieves the same function, such as a cylinder, an electric push rod, etc.

[0022] Reference Figure 4 A slide groove 401 is provided at the bottom of the slide seat 4, a slider 604 is provided on the telescopic tube 6, a guide rod 402 is provided inside the slide groove 401, the slider 604 is provided in the slide groove 401, the guide rod 402 passes through the slider 604, and a return spring 403 is provided on the guide rod 402 between the slider 604 and the bottom of the slide groove 401. When the telescopic tube 6 moves toward the mounting seat 3, the return spring 403 is compressed. After the sealing ring 1 is installed, the return spring 403 pushes the telescopic tube 6 to reset so that the cutting bolt 603 is separated from the air pipe joint.

[0023] A buffer chamber 601 is provided on one end of the telescopic tube 6 adjacent to the crank arm support 5, an end cover 605 is provided on the outer edge of the buffer chamber 601, a pressure plate 701 is provided on the loading column 7 in the buffer chamber 601, and a buffer spring 606 is provided between the pressure plate 701 and the bottom of the buffer chamber 601. The buffer spring 606 is used to buffer the loading column 7 when the sealing ring is pushed into the inside of the trachea joint to avoid damage to the sealing ring or the trachea joint, and also has the function of resetting the loading column 7.

[0024] The specific implementation methods of the utility model described above do not constitute a limitation on the protection scope of the utility model. Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
