Specifically, the handle 52 can be rotated to move the main rod 3 away from the sleeve 4, thereby driving the pressing member 1 to press the sealing ring 2. The limiting portion 513 can define the maximum angle of rotation of the handle 52, thereby limiting the pressing of the pressing member 1. The maximum extent of the sealing ring 2, at which point the conduction joint reaches the self-locking state.

Referring to FIG. 6, the hand holding portion 522 inserts the pressing member 1, the sealing ring 2, and the sleeve front portion 41 of the conduction joint into the detected channel 01, and the positioning end surface 411 is fixed to the end surface of the detected channel 01. connection. It can be understood that the outer diameter of the pressing member 1, the sealing ring 2, and the front portion 41 of the sleeve match the inner diameter of the detected passage 01. The outer diameter of the pressing member 1 and the front portion 41 of the sleeve may be smaller than or equal to the inner diameter of the detected passage 01, and the outer diameter of the sealing ring 2 may be slightly smaller than or equal to the inner diameter of the detected passage 01. The outer diameter of the sleeve rear section 42 is larger than the inner diameter of the detected passage 01, so that the positioning end surface 411 is fixedly connected to the end surface of the detected passage 01. At this time, the pressing member 1 has no pressing force on the sealing ring 2.

Referring to FIG. 5 and FIG. 7, since the inner diameter of the sleeve front section 41 is smaller than the outer diameter of the main rod rear section 33, the sleeve front section 41 limits the main rod rear section 33 toward the front of the casing. 41 sports. The distance between the rear end surface 302 of the main rod and the sleeve connecting member 43 is smaller than the length of the linear connection of the rotating bearing 51 and the mounting portion 52, so that the rotating bearing 51 and the mounting portion 52 can only Polyline connection. Therefore, the first rotating hole 512, the first positioning hole 431, and the first advancing and retracting hole 524 connect the main rod 3, the mounting portion 521, the rotary bearing 51, and the sleeve connecting member 43 together to form a triangular structure. The second positioning hole 511 and the first advancing and retreating hole 524 are respectively distributed on the axis of the main rod 3, and the first rotating hole 512 is located in the first positioning hole 431 and the first advancing and retreating hole 524.

In this state, the hand portion 522 and the main rod 3 have an acute angle.

Referring to FIG. 6 and FIG. 7 together, in use, the positioning end surface 411 abuts the detected passage opening, so that the sleeve 4 is fixed in position, and the first rotating hole 512 is centered in a clockwise direction. Rotating the pair of handles 52 to rotate the first rotating hole 512 counterclockwise around the second positioning hole 511, pulling the first advancing and retracting hole 524 to move away from the sleeve 4, thereby driving the The main rod rear section 33 moves away from the sleeve 4 to move the pressing member 1 toward the sleeve 4 to press the sealing ring 2, When the pair of handles 52 are rotated to abut the limiting member 513, the radial dimension of the sealing ring 2 is maximum at this time, and the conductive joint reaches a self-locking state to block the detected channel.

Referring to FIG. 7 to FIG. 9 together, in the embodiment, the conduction joint is installed after the passage opening of the detected passage, and the detection air pipe is connected to the conduction joint. The hand grip portion is fixed, and the positioning end surface of the conduction joint abuts against the end surface of the detected passage and the sleeve 4 is not moved, and the hand portion is rotated clockwise in the a direction shown in FIG. Since the second positioning hole 511 is fixed, the first advancing and retracting hole 524 can only move linearly in the axial direction, and the rotating force drives the first rotating hole 512 to move upward along the b direction, thereby pushing the first advancing and retracting hole 524 along The c direction moves rearward relative to the sleeve 4. Due to the obstruction of the limiting portion 513, when the first rotating hole 512 rises in line with the second positioning hole 511 and the first advancing and retracting hole 524, the self-locking of the conduction joint is reached. status. The positional relationship of the first rotating hole 512, the second positioning hole 511, and the first advancing and retracting hole 524 in the self-locking state of the through joint is as shown in FIG. 8. The overall structure of the conductive joint in the self-locking state is shown in FIG.

Referring to FIG. 8 to FIG. 11 , after reaching the self-locking state, the first advancing and retracting hole 524 is connected to the rear end of the second main pole rear section 332 , and the backward movement of the first advancing and retracting hole 524 drives the main rod 3 . Moving backwards, the rearward movement of the main rod 3 causes the pressing member 1 to move rearward relative to the sleeve 4. At this time, the limiting boss 335 of the rear section 33 of the main rod no longer abuts against the second abutting surface 412 of the front section 41 of the sleeve, but generates a certain gap with the front section 41 of the sleeve. The effect is shown in Figure 10.

Please refer to Figure 8 to Figure 11, see figure? (to be written, the above is also), after reaching the self-locking state, the pressing member 1 moves axially toward the sleeve 4, and the sleeve 4 is fixed, thereby causing the pressing member 1 to be sandwiched between The sealing ring 2 between the sleeves 4 is pressed and deformed, resulting in an increase in the radial diameter of the sealing ring 2, thereby sealing the gap between the conducting joint and the detected passage, ensuring that the conductive joint is sealed from the detected passage. Good sex. The sealing ring 2 produces a deformation seal. The effect of the detection channel is as shown in FIG. When the gas is introduced into the trachea, the gas flows into the detected channel from the hollow channel of the conducting joint. Since the sealing joint is well sealed with the detected channel, the gas pressure in the detecting trachea and the detected channel can be detected. The leak detection process of the detected channel is completed.

Please refer to Figure 6 to Figure 9, ibid. When the conductive joint is unlocked, the pair of handles 52 are pivoted counterclockwise around the first rotating hole 512, and the first rotating hole 512 is rotated clockwise around the second positioning hole 511. Pushing the first advancing and retracting hole 524 toward the sleeve 4 to move the main rod rear section 33 toward the sleeve 4 to drive the pressing member 1 away from the sleeve 4 Moving, releasing the sealing ring 2, when the main rod rear section 33 is moved to abut against the sleeve front section 41, the radial diameter of the sealing ring 2 is restored, and the conduction joint reaches an unlocked state, Then tightly sealed to the detected channel, the conductive connector can be pulled out of the detected channel.

The embodiments of the present application have been described in detail above, and the principles and implementations of the present application are described in the specific examples. The description of the above embodiments is only used to help understand the method of the present application and its core ideas; A person skilled in the art will have a change in the specific embodiments and the scope of the application according to the idea of the present application. In summary, the content of the present specification should not be construed as limiting the present application.
