Offseted with the bottom of chamber 358 of shell accommodating cavity；
Spacing stopper 359 is provided with the shell accommodating cavity 354；
When the bottom face 308 of the base portion of the expansion link offsets with spacing stopper 359, it is maximum that the expansion link 302 is in retraction
Position；
When the bottom land 341 of the removable pin 305 and side channel offsets, the expansion link 302, which is in, stretches out maximum position；
The expansion link 302 is stretching out motion between maximum position and retraction maximum position；
High-end the 325 of first tilting section are connected with the upper end 326 of changeover portion by the first arc section 360, and this second inclines
Tiltedly high-end the 329 of section it is connected with descending section of head end 315 by the second arc section 361, the circle at the place of first arc section 360,
The radius of circle and removable pin 305 where second arc section 361 is equal；
When the arc section 360 of removable pin 305 and first or the second arc section 361 offset, the bottom of the base portion of the expansion link
End face 308 offsets with spacing stopper 359；The technical scheme can cause the removable pin and first by setting spacing stopper 359
When arc section or the second arc section offset, the bottom face 308 of base portion just also offsets with spacing stopper 359, can so carry
The stability and reliability of high expansion link motion, for example, avoid expansion link from occurring clamping stagnation in relative movement with removable pin and show
As and cause expansion link not move；
When removable pin 305 is in side channel 320, the valve element 20 is in the open position；
When removable pin 305 rests in the centre position 332 of lower groove side of upper lead segment, the valve element 20 is in close stance
Put.
The compression spring 303 has makes expansion link 302 from retraction maximum position to becoming that stretching maximum position is moved all the time
Gesture.
The operation principle of the telescoping mechanism of the present invention is as follows：
As illustrated in fig 16 a, when removable pin 305 is in side channel 320, and application external force (not shown in figure, the external force of the application
Can act on expansion link 302) drive expansion link 302 to overcome the active force of compression spring 303 and into shell accommodating cavity 354
Make retraction campaign, removable pin 305 first imports and exports 342 from side channel and enters lower lead segment 319, then the with the upper groove side of lower lead segment
Three tilting sections 334 offset (as shown in fig 16b), and by the upper groove side of lower lead segment the 3rd tilting section 334 guiding to up
The head end 318 (as shown in figure 16 c) of section, then move to up section of end 314 from up section of head end 318 along up section 313
And enter upper lead segment 316, then offseted with the first tilting section 321 of the upper groove side of upper lead segment, and by the upper groove of upper lead segment
First tilting section 321 of side is guided to the first arc section 360 and offseted (as shown in figure 16d) with the first arc section 360, now should
The bottom face 308 of the base portion of expansion link offsets with spacing stopper 359, and expansion link 302 is in retraction maximum position.In revocation external force
Afterwards, the effect of compressed spring 303, compression spring 303 drives expansion link 302 to make to stretch out motion, removable pin 305 and upper lead segment
Lower groove side 362 offset that (as shown in figure 16e, especially removable pin 305 and the right-hand member 331 of the lower groove side from upper lead segment is supreme
The lower groove side of one section of upper lead segment between the centre position 332 of the lower groove side of lead segment offsets), by the lower groove side of upper lead segment
The centre position 332 of the 362 lower groove side for being directed to lead segment, and finally rest in the interposition of the lower groove side of lead segment
332 (as shown in Figure 16 f) are put, now the body 215 of filling in of sealing-plug is inserted in the sealing ring perforation 503 of sealing ring, at valve element 20
In closed position.
As shown in Figure 16 f, when removable pin rests in the centre position 332 of lower groove side of upper lead segment, apply external force (figure
Not shown in, the external force of the application can be acted on expansion link 302) drive expansion link 302 to overcome the effect of compression spring 303
Power and make retraction again into shell accommodating cavity 354 and move, the second tilting section of removable pin 305 first with the upper groove side of upper lead segment
323 offset (as shown in Figure 16 g), and are guided by the second tilting section 323 of the upper groove side of upper lead segment to the second arc section 361 simultaneously
Offseted (as shown in Figure 16 h) with the second arc section 361, now the bottom face 308 of the base portion of the expansion link and the spacing phase of stopper 359
Support, expansion link is in retraction maximum position, the removable pin 305 enters descending section of head end 315.It is compressed after revocation external force
The effect of spring 305, compression spring 305 drives expansion link 302 to make to stretch out motion, and removable pin 305 is from descending section of the edge of head end 315
Move to for descending section 312 descending section end 317 and enter lower lead segment 319 (as shown in Figure 16 i), and with lower lead segment
The outer arc segments 337 of groove side offset, and are guided by the outer arc segments 337 of the lower groove side of lower lead segment to side channel and import and export 342 (as schemed
Shown in 16j), and (as shown in Figure 16 a or Figure 16 k) is fallen into side channel 320 from side channel import and export 342, as shown in Figure 16 K, when
When the bottom land 341 of removable pin 305 and side channel offsets, the expansion link 302, which is in, stretches out maximum position.
The technical scheme can simplify the structure of telescoping mechanism by rail groove reasonable in design, be easy to manufacture, just
In realizing telescopic movable to expansion link, and stretching motion has higher stability and reliability；
The technical scheme is by setting stop collar to be easy to activity in order to the assembling of removable pin and stop collar and expansion link
Pin stretches into cooperation in rail groove, by setting stop collar chute to carry out spacing activity to removable pin on stop collar.
It is in the open position in valve element 20, under the enlarged diameter section 210 of the outer end 356 in the push rod portion of expansion link and lower mandrel
End is offseted, and valve element projection 202 offsets with valve element locking plate 105, and removable pin 305 is in side channel 320 but the not bottom land 341 with side channel
Offset (as illustrated in fig 16 a)；The technical scheme can cause valve element to be in the thrust of the outer end in the push rod portion by expansion link all the time
Effect, it is to avoid valve element loosens, improves the precision coordinated.
The section of the base portion 306 of the expansion link is square, and the stop collar 304 is square sleeve, can so cause stop collar
Activity progress to expansion link is spacing；
The two opposite side surfaces 310 of the base portion of the expansion link are respectively equipped with a rail groove 311, with setting on the stop collar 304
The corresponding side wall 352 in side 310 for having the base portion of the expansion link of rail groove is respectively equipped with a stop collar chute 353, each stop collar
Chute 353 is respectively provided with a removable pin 305；One rail groove 311, a stop collar chute 353 and a removable pin 305 constitute one group and stretched
Contracting activity operations unit, the technical scheme distinguishes one group of telescopic movable operating unit by the opposite sides of the base portion in expansion link
The reliability and stability of motion can be improved；
The shell 301 is put together by two structure identical half-shells, in order to the dismounting of telescoping mechanism；
The convex portion 364 in a ring of shell aperture 355 is provided around on the shell 301；
The telescoping mechanism also includes the flexible sealing shroud 365 of rubber being placed on outside the push rod portion of expansion link, and the rubber stretches close
One end of big envelope 365 is installed on convex portion 364, and the other end of the flexible sealing shroud 365 of the rubber is installed in the push rod of expansion link
On the outer end 356 in portion.The technical scheme prevents water from entering shell by setting the flexible sealing shroud of rubber to play waterproof effect
