Make.
Its working principles are as follows:
A normal state is shown in that Fig. 7, spring are cased with the power F1 of a pushing to bias, can compress eccentric bushing and axle sleeve, when
When gas spring pops up, eccentric bushing can generate the downward frictional force in direction, active force and reaction force principle to gas spring push rod, partially
Heart set will receive upward reaction force f1, offset spring downward power, so that eccentric bushing and axle sleeve is released impaction state, gas spring can
Pop-up;When giving the power F2 of one retracted orientation of gas spring push rod, eccentric bushing can make one upward frictional force of gas spring bar
Firmly with reaction force principle, eccentric bushing will receive downward reaction force f2;Pushing eccentric bushing, tighter, frictional force is bigger.
Gas spring is prevented to retract.
Purposes: to mounting table above lifting device, table top weight is greater than gas spring elastic force, under normal state, gas
The push rod of spring is only popped up and can not be retracted;Weight is then put on table top to be declined, since table top weight is greater than gas spring bullet
Power, table top will not rise;Rise table top only and need and lifts table top upwards and can rise.Needing to decline table top then pulls gas spring to draw
Hand, table top decline.
B pull rod driving status is shown in Fig. 8: driving change to rotate (pull rod power is F3) around rotating shaft when pull-rod operator pulls, turns
Ring inclination, the corresponding end surface drive respective side of change biases eccentric bushing, so that eccentric bushing can be detached from axle sleeve, eccentric bushing
Inner wall compress gas spring push rod, wherein pull rod power F3 be greater than spring force;When gas spring pops up, eccentric bushing can be to gas
The push rod of spring generates downward frictional force, active force and reaction force principle, and eccentric bushing will receive upward reaction force
F3 makes eccentric bushing the more press the more tight with gas spring push rod, and gas spring can not pop up;When gas spring retract when, eccentric bushing will receive to
Under active force f4, so that eccentric bushing and the push rod of gas spring is released impaction state, gas spring regracting;To which pull-rod operator is drawn
Under dynamic state, the push rod regracting of gas spring can not be popped up.
Specific embodiment of the utility model is described in detail above, but content is only what the utility model was created
Preferred embodiment should not be construed as limiting the practical range of the utility model creation.All create according to the utility model is applied
All the changes and improvements made by range etc., shall still fall within the scope of this patent.
