In use, the positioning device 20 and the buffer unit 40 are accordingly run with the rotation of the outer tube 11,
For the positioning device 20, the cord 2 is pulled down by the operating parts 3, the cord 2 moves down exhibition
It opens, the outer tube 11 drives the outer housing 31, actuator 224 and the hydraulic damper 223 to be rotated counterclockwise,
The tightening of main spring 221 generates elastic force, and the lock pin 32 of the outer housing 31 drives the locating piece 34 to rotate, the lock
Pin 32 is relatively mobile from second positioning area 344 to first positioning area 343, in first positioning area 343,
The lock pin 32 drives the locating piece 34 to keep rotating counterclockwise, as shown in Figure 11 A；
If be deployed into the height of anticipation, half, pause drop-down movement, the outer housing 31, actuator 224 is such as unfolded
And hydraulic damper 223 stops rotating counterclockwise, due to the elastic force of the main spring 221, the outer housing 31 drives institute
It states lock pin 32 and carries out rotating clockwise slightly, meanwhile, the locating piece 34 makes since inertia continues to rotate counterclockwise
It obtains the lock pin 32 and is relatively moved to third positioning area 345 from first positioning area 343, it is as shown in Figure 12 B, described fixed
Position part 34 slides axially, close to the non return part 33, until the protruding portion 348 locks in the non-return portion 331, Jin Ersuo certainly
The fixed locating piece 34 and the lock pin 32, the coupling mechanism force payment after loosing one's grip, between the locating piece 34 and the non return part 33
The elastic force of the main spring 221 is realized so that the cord 2 is held in stop place and quickly stops arbitrary height；
When pulling down again, the rotation counterclockwise of lock pin 32, while driving the locating piece 34 to rotate, the lock pin
32 are relatively moved to first positioning area 343 from the third positioning area 345, as indicated in fig. 12 c, the locating piece 34
It is mobile to be axially displaced from the non return part 33, until the protruding portion 348 is detached from the non-return portion 331, the lock pin 32 and described
Locating piece 34 is in the unlocked state, and the outer tube 11 rotates again；
After loosing one's grip, the cord 2 rises automatically, and by the release of elastic force, the main spring 221 pushes the outer tube
11 rotate clockwise, and the hydraulic damper 223 reduces the rate of climb of the cord 2, so that the cord 2 slowly rises,
The lock pin 32 is relatively moved to second positioning area 344 from first positioning area 343, in second positioning area
In 344, the lock pin 32 drives the holding of locating piece 34 to rotate clockwise, as indicated in fig. 12d.
For buffer unit 40, when pulling down the cord 2, the buffering nut 42 turns with the outer tube 11
It is dynamic to deviate the movement of stationary contact portion 412, until the outer tube 11 stops movement；When the cord 2 rises, the buffering spiral shell
Mother 42 rotates backward with the outer tube 11 close to the stationary contact portion 412, until the buffering nut 42 is butted on the stationary contact
Portion 412, so that the outer tube 11 stops operating, according to the default spacing of the buffering nut 42, the operating parts 3 is risen to
Reserved height is out of service.
