Description
Technical field
This utility model relates to gas spring technology field, especially relates to a kind of range-adjustable air spring.
Background technology
Air spring is mainly made up of the piston in cylinder barrel, cylinder barrel, piston rod and valve rod etc., and in cylinder barrel, storage has
Gas or storage have gas mixture.The volume in cylinder barrel has been occupied, so utilizing the horizontal stroke of piston rod due to piston
Sectional area is less than the cross-sectional area of piston thus the pressure differential produced is to realize the motion of piston rod.
Existing air spring cannot meet the occasion being continually changing at some stroke needs, operates comparatively laborious,
Affect work efficiency.
Utility model content
The technical problems to be solved in the utility model is: cannot meet at some row to solve existing air spring
Journey needs the problem of the occasion being continually changing, and now provides a kind of range-adjustable air spring.
This utility model solves its technical problem and be the technical scheme is that a kind of range-adjustable air spring,
Including cylinder body and the piston rod that is arranged on cylinder body one end, also include outer sleeve and lock-screw, described outer sleeve
Being slidably arranged on described cylinder body, described outer sleeve one end and described piston rod are fixing even away from one end of cylinder body
Connecing, described cylinder body axially offers groove along it, and described groove both sides are provided with projection, and described groove is positioned at institute
Stating the slide block that projection is provided above matching with it, described groove is positioned at below described projection and is provided with movable block,
Threaded with described slide block in one end of described lock-screw, the other end of described lock-screw and described activity
Block is rotationally connected, and described outer sleeve offers the chute matched with described slide block, and described slide block is arranged on
In described chute, by the position of adjusting slider, control the stroke of air spring, lock-screw fastening
Slide block, its simple in construction, convenient to operation, it is to avoid cannot to meet and be continually changing at some stroke needs
Occasion, operate comparatively laborious, the problem affecting work efficiency.
In order to prevent air spring inefficacy and piston rod from going out cylinder body, make outer sleeve and slide block when air spring lost efficacy
There is certain buffering effect, further, be provided with between described chute both ends of the surface and described slider contact surface
Flexible member, owing to being provided with flexible member between chute both ends of the surface and slider contact surface, it is ensured that air spring again
There is during inefficacy certain buffering effect.
In order to make that there is between outer sleeve and slide block good buffering effect, further, described flexible member
For spring, owing to flexible member is spring, spring is that one has good elastic part, and it has mutability
The characteristics such as shape, elasticity are big, and be widely used, it is ensured that there is good buffering to imitate between outer sleeve and slide block
Really.
The beneficial effects of the utility model are: this utility model range-adjustable air spring in use, by adjust
The position of joint slide block, controls the stroke of air spring, lock-screw is fastening slide block, its simple in construction,
Convenient to operation, it is to avoid cannot to meet the occasion being continually changing at some stroke needs, operate ratio
Problem that is cumbersome, that affect work efficiency；Owing to being provided with elastic unit between chute both ends of the surface and slider contact surface
Part, it is ensured that air spring had certain buffering effect when losing efficacy again；Owing to flexible member is spring, spring
Being that one has good elastic part, it has the characteristic such as greatly yielding, elastic, and is widely used,
Ensure that between outer sleeve and slide block, there is good buffering effect；This utility model can be as desired to regulate
The stroke of air spring, has certain buffering effect when air spring lost efficacy, and its simple in construction is easy to operate
Fast.

Detailed description of the invention
Presently in connection with accompanying drawing, the utility model is described in more detail.These accompanying drawings are showing of simplification
Being intended to, basic structure of the present utility model is described the most in a schematic way, therefore it only shows and this utility model
Relevant composition.
Embodiment 1
As shown in Fig. 1,2,3 and 4, a kind of range-adjustable air spring, including cylinder body 1 and be arranged on cylinder body
The piston rod 2 of 1 one end, also includes that outer sleeve 3 and lock-screw 4, described outer sleeve 3 are slidably arranged in institute
Stating on cylinder body 1, described outer sleeve 3 one end and described piston rod 2 are connected away from one end of cylinder body 1 is fixing,
Described cylinder body 1 axially offers groove 5 along it, and described groove 5 both sides are provided with protruding 6, described groove 5
Being provided above, in described protruding 6, the slide block 7 that matches with it, described groove 5 is positioned at below described protruding 6
Being provided with movable block 8, threaded with described slide block 7 in one end of described lock-screw 4, described lock-screw 4
The other end be rotationally connected with described movable block 8, described outer sleeve 3 offers and described slide block 7 phase
