52, mobile jib 3 can be driven to be moved away from sleeve pipe 4, so as to drive the crush seal circle 2 of casting die 1, limiting section 513 can limit handle 52
The maximum angle of rotation, so as to limit the crush seal circle 2 of casting die 1 at utmost, now turns on joint and reaches self-locking state.
Referring to Fig. 6, holding Handheld Division 522, the casting die 1, sealing ring 2, the sleeve pipe leading portion 41 that turn on joint are inserted tested
Survey in passage 01, the positioning end face 411 is fixedly connected with the end face of the detected passage 01.It is understood that described
The internal diameter of casting die 1, sealing ring 2, the external diameter of sleeve pipe leading portion 41 and detected passage 01 matches.The casting die 1 and sleeve pipe leading portion
41 external diameter can be less than or equal to the internal diameter of the detected passage 01, and the external diameter of the sealing ring 2 can be slightly less than
Or equal to the internal diameter of the detected passage 01.The external diameter of described sleeve pipe back segment 42 is more than the interior of the detected passage 01
Footpath, in order to which the positioning end face 411 is fixedly connected with the end face of the detected passage 01.Now, described in 1 pair of the casting die
Sealing ring 2 is without extruding force.
Also referring to Fig. 5 and Fig. 7, because the internal diameter of described sleeve pipe leading portion 41 is less than the external diameter of the mobile jib back segment 33,
Described sleeve pipe leading portion 41 limits the mobile jib back segment 33 and moved towards sleeve pipe leading portion 41.The mobile jib rear end face 302 with it is described
The distance between casing joints 43 are less than the length that the swivel bearing 51 is connected with the straight line of installation portion 52 so that described
Swivel bearing 51 and the installation portion 52 can only broken line be connected.So the first rotating hole 512, first positioning hole 431 and institute
State the first advance and retreat hole 524 mobile jib 3, installation portion 521, swivel bearing 51, casing joints 43 link together, form triangle
Structure.Second positioning hole 511 is one in front and one in back distributed on the axis of mobile jib 3 respectively with the first advance and retreat hole 524, and the first rotation
Turn hole 512 is located between first positioning hole 431 and the first advance and retreat hole 524, and below the axis of mobile jib 3.Wherein
Mobile jib 3 is longest edge, and installation portion 521 and swivel bearing 51 are two short sides.Under this state, the Handheld Division 522 and the master
It is at an acute angle between bar 3.
Also referring to Fig. 6 and Fig. 7, in use, the positioning end face 411 abuts the detected passway so that institute
State the position of sleeve pipe 4 to fix, the pair of handle 52 is rotated in a clockwise direction centered on first rotating hole 512, drive
First rotating hole 512 rotate counterclockwise centered on second positioning hole 511, pulls the first advance and retreat hole 524 to carry on the back
Moved from described sleeve pipe 4, so as to drive the mobile jib back segment 33 to be moved away from described sleeve pipe 4, to drive the casting die 1 towards institute
State sleeve pipe 4 to move, extrude the sealing ring 2, the pair of handle 52 is rotated to when abutting the locating part 513, now described
The radial dimension of sealing ring 2 is maximum, and the conducting joint reaches self-locking state, to block detected passage.
Also referring to Fig. 7 to Fig. 9, in the present embodiment, joint will be turned on and be installed on the logical of the detected passage
Behind road junction, and detection tracheae is connected to conducting joint.Hold Handheld Division, it is ensured that the positioning end face of conducting joint, which is abutted, to be detected
The channel end surface and position of sleeve pipe 4 is motionless, Handheld Division is turned clockwise according to a directions shown in Fig. 7.Due to the second positioning hole
511 is fixed, and the first advance and retreat hole 524 can only move along a straight line vertically, then the revolving force drive the first rotating hole 512 along
B is moved in direction upwards, so as to promote the first advance and retreat hole 524 to be moved backward relative to sleeve pipe 4 along c directions.Due to described spacing
The inhibition in portion 513, when first rotating hole 512 rises to and second positioning hole 511, the first advance and retreat hole
524 point-blank when, reach conducting joint self-locking state.First rotating hole described in during the self-locking state of conducting joint
512nd, second positioning hole 511, the position relationship of the first advance and retreat hole 524 are as shown in Figure 8.Conducting joint during self-locking state
Overall structure diagram is as shown in Figure 9.
Fig. 8 to Figure 11 is referred to, after self-locking state is reached, the first advance and retreat hole 524 is connected to the second mobile jib back segment
332 rear end, the motion backward in the first advance and retreat hole 524 drives the mobile jib 3 to move backward, the motion band backward of the mobile jib 3
The casting die 1 is moved to move backward relative to sleeve pipe 4.Now, the positive stop lug boss 335 of the mobile jib back segment 33 no longer with described sleeve pipe
Second bearing surface 412 of leading portion 41 is abutted against, but produces certain gap with described sleeve pipe leading portion 41, its effect such as Figure 10 institutes
Show.
Fig. 8 to Figure 11 is referred to, referring to figure(to write out, be also above) after self-locking state is reached, casting die 1 is along axle
Moved to sleeve pipe 4, and described sleeve pipe 4 is fixed, so as to cause to be folded in close between the casting die 1 and described sleeve pipe 4
Seal 2 is extruded and produces deformation, causes the radial diameter of sealing ring 2 to increase, so as to seal and conduct joint and detected passage
Between gap, it is ensured that conducting joint and detected passage sealing it is good.Sealing ring 2 produces deformation sealing and is detected passage effect
Fruit is as shown in figure 11.When being passed through gas in detection tracheae, the hollow passageway of the gas from conducting joint, which is flowed into, is detected passage
In, because conducting joint is good with detected passage sealing, detection tracheae can be achieved and is turned on the air pressure in detected passage,
Complete the sealing propertytest process of detected passage.
Fig. 6 to Fig. 9 is referred to, ibidWhen turning on joint unblock, along counterclockwise centered on first rotating hole 512
Direction moves the pair of handle 52, drives the dextrorotation centered on second positioning hole 511 of the first rotating hole 512
Turn, promote the first advance and retreat hole 524 to be moved towards described sleeve pipe 4, so as to drive the mobile jib back segment 33 towards described sleeve pipe 4
Motion, to drive the casting die 1 to be moved away from described sleeve pipe 4, discharges the sealing ring 2, the mobile jib back segment 33 be moved to and
When described sleeve pipe leading portion 41 is abutted against, the radial diameter of the sealing ring 2 is recovered, and the conducting joint reaches released state, no
Conducting joint can be extracted in the detected passage and be detected passage by tight seal again.
In summary, although the utility model is disclosed above with preferred embodiment, but the preferred embodiment and it is not used to
The utility model is limited, one of ordinary skill in the field is not being departed from spirit and scope of the present utility model, can make each
Plant and change with retouching, therefore protection domain of the present utility model is defined by the scope that claim is defined.
Described above is preferred embodiment of the present utility model, it is noted that for the ordinary skill of the art
For personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and moistened
Decorations are also considered as protection domain of the present utility model.
