The corresponding pipe air valve hole 102 in the position of air valve hole 312, air valve 4 is set in end socket air valve hole 312 and pipe air valve hole 102, end socket sheet
The bosom horizontal injection of body 31 has central dividing plate 318, and shape is distinguished between central dividing plate 318 and two end socket air valve holes 312
Into an enterprising stomata 316 and a lower air admission hole 317, enterprising stomata 316 is located at the top of central dividing plate 318, lower air admission hole 317
Positioned at the lower section of central dividing plate 318.
At least one set of stroke dog fixing hole 103, outer tube 1 and inner tube are offered on described outer tube 1 and the tube wall of inner tube 2
2 outside is fixed with stroke dog 91 by stroke dog fixing hole 103, and the inner side of stroke dog 91 is provided with insertion stroke gear
The fixing lug boss 913 of block fixing hole 103, the top of stroke dog 91 is set to collide side 911, and the lower section on collision side 911 is opened
Provided with some damping troughs 912, the bottom both sides of stroke dog 91 are disposed as inclined hypotenuse 915.
The outside of described end socket main body 31 offers seal groove 313 and lower seal 314, upper seal groove 313
Sealing ring 71 is inside arranged with, upper sealing ring 71 is contacted with the inwall of inner tube 2, and lower seal is arranged with lower seal groove 314
81, lower seal 81 is contacted with the inwall of outer tube 1.
Described air valve 4 includes air valve body 41, and the outer end of air valve body 41 offered air drain 412, the inner sleeve of air valve body 41
Provided with steel ball 51 and the steel ball spring 61 of holding one's breath, one end top pressure of steel ball spring 61 is holding one's breath on steel ball 51, other end top pressure is in end socket
The inner in air valve hole 312, steel ball 51 of holding one's breath is pressed in the valve seal groove 413 in air valve body 41 by the elastic force of steel ball spring 61,
The buckle 411 of outwardly convex is provided with the outer wall of air valve body 41, buckle 411 is buckled in enterprising stomata 316 or lower air admission hole 317
It is interior.
The outside of described end socket main body 31 is molded with brace rod piece 315 vertically.
After upper sealing ring 71 and lower seal 81 are adjacent to the inwall of inner tube 2 and outer tube 1 respectively, on central dividing plate 318
The air of side can only be by the unidirectionally controlled entrance of enterprising stomata 316 and air valve 4.The air of lower section can only pass through lower air admission hole
317 and air valve 4 enter.
Steel ball 51 hold one's breath under the effect of steel ball spring 61 in the seal groove 413 that is close in air valve body 41, when air is from upper
When air admission hole 316 or lower air admission hole 317 enter air inlet valve 4, air pressure forces what steel ball 51 of holding one's breath more stepped up to be fitted in air valve body 41
Seal groove 413 in, air can not be discharged.When air flows from air valve 4 into end socket main body 31, air pressure, which is forced, holds one's breath
Steel ball 51 is moved to the direction of steel ball spring 61, and steel ball spring 61 is compressed, and steel ball 51 of holding one's breath departs from seal groove 413, and air can
To enter from air valve 4.
End socket main body 31 and the entirety of air valve 4 are assembled in inner tube 2 and the lower end of outer tube 1, the insertion outer tube 1 of inner tube 2, in inner tube 2
A closed cavity is formed between bottom and the bottom of outer tube 1, when inner tube 2 is moved to the bottom of outer tube 1, air is first from outer tube 1
Steam vent 101 discharge rapidly, the translational speed of inner tube 2 is unaffected.When the end socket main body 31 of the lower end of inner tube 2 is crossed on outer tube 1
Steam vent 101 after, air can not be discharged quickly, and inner tube 2 is moved down by resistance, and speed slows down.
When the bottom of inner tube 2 is moved up from the bottom of outer tube 1, air enters in closed cavity via air valve 4, inner tube
2 translational speeds are unaffected.So as to often save one section of slow drop stroke when realizing that section of ladder is drawn in, when pulling open, and not by closed gas
The influence of chamber.
Stroke dog 91 is fixed on outer tube 1 or the outside of inner tube 2 by stroke dog fixing hole 103 and fixing lug boss 913
On wall, after the insertion outer tube 1 of inner tube 2, the fixing lug boss 913 that the inwall of outer tube 1 is limited on stroke dog 91 is solid from stroke dog
Determine to deviate from hole 103, it is ensured that what stroke dog 91 can be consolidated all the time is fixed on the lateral wall of inner tube 2.
When inner tube 2 is moved up and down in outer tube 1, the stroke dog 91 in inner tube 2 follows inner tube 2 to move up and down, when inner tube 2
Move up after certain distance, the collision side 911 of the top of stroke dog 91 can be collided with preset retention device, prevent stroke from keeping off
Block 91 is continued to move up, so as to prevent inner tube 2 from moving up.
The damping trough 912 of the lower section of side 911 is collided, the impulsive force that part collision is produced can be eliminated, stroke dog 91
Bottom both sides are disposed as inclined hypotenuse 915, convenient for assembly, the contact area of increase stroke dog 91 and pipe.
