Abstract
The utility model relates to the field of air spring technology, and particularly relates to an ultra-long air spring, comprising a cylinder body, a piston and a piston rod, one end in the cylinder body is successively provided with a guiding sleeve and a spacer sleeve, the other end in the cylinder body is provided with a back plug, the internal of the cylinder body is provided with a piston, an O-shaped sealing ring is disposed between the piston and the inner wall of the cylinder body, one end of the piston rod extends into the internal of the cylinder body to successively go through the guiding sleeve and the spacer sleeve, after the end portion and the piston are in a screw thread connection, a hexagonal nut is used for fixation. The ultra-long air spring is advantageous in that, double guidance of the piston rod is performed via the guiding sleeve and the spacer sleeve, greatly improving operation stability of the piston rod in a telescoping process, thereby facilitating realization of ultra-long disposing of the ultra-long air spring, and widening the application field and the application scope of the ultra-long air spring.
Description
Technical field
The utility model relates to the air spring technical field, particularly a kind of overlength air spring.
Background technique
Air spring is as the conventional machinery component unit, and common for people institute, it is widely used in every field such as medical apparatus, furniture and auto parts machinery, in the air spring generally with oil, gas or gas mixture as transmission medium.Existing air spring is reasonable inadequately because of structure is provided with, and the length setting receives certain limitation, and existing air spring generally is no more than one meter, so inevitable application and application area that influences air spring.So existing air spring is carried out the structure innovation to be necessary in fact.
The model utility content
The purpose of the utility model is defective and the deficiency to existing technology, the overlength air spring that a kind of compact structure is provided, operates steadily.
For realizing above-mentioned purpose, the utility model adopts following technological scheme:
The described a kind of overlength air spring of the utility model comprises cylinder body, piston and piston rod; An end is established guide sleeve and spacer successively in the said cylinder body, and the other end is provided with the back shutoff in the cylinder body, is provided with piston in the said cylinder body; Be provided with the O RunddichtringO between piston and the inboard wall of cylinder block; Said piston rod one end stretches into and passes guide sleeve and spacer in the cylinder body successively, and its end is fixed with hexagon nut with after piston thread is connected.
Further, be provided with seal ring between said guide sleeve and the spacer.
Further, said back shutoff is provided with annular slot along perisporium, the corresponding bulge loop that is provided with on the said cylinder body one end inwall.
Further, an end end of shutoff was provided with joint after said cylinder body was provided with.
After adopting said structure; The utility model beneficial effect is: the utility model carries out two guiding through guide sleeve and spacer to piston rod; Greatly improved traveling comfort in the piston rod telescopic process; Thereby be effective in the overlength setting that realizes model utility, widened the utility model application and application area.
Description of drawings
Fig. 1 is the sectional structure schematic representation of the utility model.
Among the figure:
1, piston rod 2, guide sleeve 3, seal ring 4, spacer;
5, piston 6, cylinder body 7, back shutoff 8, joint;
9, annular slot; 10, bulge loop 11, hexagon nut; 12, O RunddichtringO.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, the described a kind of overlength air spring of the utility model comprises cylinder body 6, and piston 5 and piston rod 1 also are cylinder body 6, and piston 5 and piston rod 1 constitute the utility model agent structure.
An end is established guide sleeve 2, seal ring 3 and spacer 4 successively in the said cylinder body 6, is provided with piston 5 in the said cylinder body 6, is provided with O RunddichtringO 12 between piston 5 and cylinder body 6 inwalls.Said piston rod 1 one ends stretch into and pass guide sleeve 2, seal ring 3 and spacer 4 in the cylinder body 6 successively and be connected with piston 5.Guide sleeve 2 plays leading role to piston rod 1 together with spacer 4, smooth running when guaranteeing that piston rod 1 is flexible.Need to prove, fixing after said piston rod 1 end is threaded with piston 5 with hexagon nut 11 welding, guarantee tightness and fastness that piston rod 1 is connected with piston 5.After adopting this structure, the utility model can realize that length reaches about two meters, has greatly widened the application and the application area of the utility model.
The other end is provided with back shutoff 7 in the said cylinder body 6; Said back shutoff 7 is provided with annular slot 9 along perisporium; The corresponding bulge loop 10 that is provided with on the said cylinder body 6 one end inwalls; Said bulge loop 10 is arranged in annular slot 9, guarantees that back shutoff 7 under high pressure moves can not break and influence the utility model overall quality.
The end end that said cylinder body 6 is provided with back shutoff 7 is provided with joint 8, is used to connect fixedly the utility model.
The above only is the preferred embodiments of the utility model, so all equivalences of doing according to the described structure of the utility model patent claim, characteristic and principle change or modify, includes in the utility model patent claim.
