Abstract
The invention provides a force changeable, cyclic and reversible angular motion gas spring. A cylinder body and a rear sealing pressure regulating system are weld together to form an enclosed gas spring cylinder body, an O-shaped ring and a directional floating piston are combined with a positioning convex groove of the cylinder body to generate friction force for an angular shaft under the action of power source nitrogen gas, meanwhile, the volume of a gas chamber is changed by the rear sealing pressure regulating system to change the value of the friction force, thus realizing cyclic and reversible motion and angular motion. The rotation friction force of the novel gas spring is changeable and adjustable, and an adjustment angle is cyclic and reversible, which can realize unlimited adjustment of a cyclic angle and can realize fixed value adjustment of the cyclic angle, and meets requirements of a certain emerging and specific products and industries.
Description
Technical field
The present invention relates to a kind of air spring, particularly a kind of gas spring with variable force value and circulating and reversible rotation angle.
Background technique
The pattern of air spring motion in the past is the single pressure stretch motion of contracting, and the air spring of the type is owing to function singleness, application is limited, can not satisfy for example medical apparatus angle adjustment especially, computer monitor, TV-set carriage angle adjustment or the like some emerging certain products and industries.
Summary of the invention
The invention provides a kind of gas spring with variable force value and circulating and reversible rotation angle.
In order to solve above technical problem, a kind of gas spring with variable force value and circulating and reversible rotation angle of the present invention, forming built-in directed floating piston in smooth rotation output unit, cylinder body, the cylinder body, power source and back envelope voltage-regulating system by the advancing slip pearl in corner axle and the cylinder body forms, described cylinder body welds together with back envelope voltage-regulating system forms airtight air spring cylinder body, described directed floating piston in the air spring cylinder body, is the power source region with O type ring seal device between described directed floating piston and back envelope voltage-regulating system.
Described corner shaft rear end can be that cone also can be the plane.
When described corner shaft rear end is the plane, the corner positioning bead is installed on this plane.
Described directed floating piston front can be that taper hole also can be the plane.
When described directed floating piston front was the plane, a basic circle had been established many equal angles in this upper edge, plane, symmetrical pit.
The advantage of above structure is: this gas spring with variable force value and circulating and reversible rotation angle welds together with back envelope voltage-regulating system by cylinder body forms airtight air spring cylinder body, O type circle and directed floating piston, in conjunction with the location tongue of cylinder body under the effect of power source nitrogen, the corner axle is produced frictional force, and change the size of frictional force simultaneously by the volume of back envelope regulating system change air cavity.Realize that like this circulating and reversible rotates, the corner motion, and this novel air spring rotation friction variable adjustable, and the angle modulation circulating and reversible.Can realize that not only cycle perspective is infinitely adjustable, can also realize that the cycle perspective definite value is adjustable.Its appearance will have been satisfied some emerging certain products and industries.It can be widely used in some occasion work light illumination direction adjusting etc.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention 1;
Fig. 2 is the structural representation of the embodiment of the invention 2.
Embodiment
Specific embodiment 1:
As shown in Figure 1, the rear end of corner axle 1 is a cone, form smooth rotation output with advancing slip pearl 3, cylinder body 2 welds together with back envelope voltage-regulating system 7 forms airtight air spring cylinder body, there is the directed floating piston 5 of taper hole O type circle 4 and front, under the effect of power source nitrogen 6, the awl end of corner axle 1 is produced frictional force in conjunction with the location tongue of cylinder body 2, back envelope regulating system 7 is the sizes that change frictional force by the volume that changes air cavity.Selecting corner axle 1 and directed floating piston 5 to be the tapered sleeve friction type in Fig. 1, is in order to strengthen the effect of frictional engagement face stable center.It is applicable on the apparatus of any change angle.
Specific embodiment 2:
As shown in Figure 2, corner axle 1 is formed smooth rotation output with advancing slip pearl 3, different is with corner axle among Fig. 11, corner axle 1 rear end is not that cone is the plane among Fig. 2, corner positioning bead 8 is just installed on this plane, cylinder body 2 welds together with back envelope voltage-regulating system 7 forms airtight air spring cylinder body, O type circle 4 is contained on the directed floating piston 5, different is that directed floating piston 5 fronts have been not taper holes, be the plane and processed many equal angles along certain circle, the symmetry pit, in conjunction with the location tongue of cylinder body 2 under the effect of power source nitrogen 6, corner axle 1 ear end face is implemented thrust, and corner positioning bead 8 at this moment just should drop on the front-end face of directed floating piston 5 in the symmetrical grooves, and corner power size is born object gravity+outer active force.Back envelope regulating system 7 is the sizes that change thrust or corner power by the volume that changes air cavity.It is applicable to the air spring of this circulating and reversible angle of Fig. 2 definite value adjustable structure on the apparatus of definite value angle modulation.
