Abstract
The utility model provides an ultra-long-stroke rigid locking adjustment level type gas spring, which comprises an ejection rod, a piston rod, a cylinder barrel, a small valve, a piston and an isolation piston and is characterized in that an inner cylinder barrel is additionally arranged in the cylinder barrel, the piston and the piston rod are arranged at one end of the inner cylinder barrel, a valve body and the ejection rod are arranged at the other end of the inner cylinder barrel, and the small valve is arranged on the valve body and can move in the valve body. The ultra-long-stroke rigid locking adjustment level type gas spring has the beneficial effects that since the small valve is arranged on the valve body, the locking and unlocking of the gas spring can be controlled via controlling the opening and closing of a channel in the valve body. The small valve can be ejected by the ejection rod without penetration of the ejection rod through the middle part of the piston rod, and the structural length of the ejection rod is not related to the stroke of the gas spring. The piston rod can be made into a solid piston rod which can be processed easily, and thus the ultra long stroke and rigid locking of the adjustment level type gas spring can be realized.
Description
Technical field
The utility model relates to a kind of rigid locking adjustable lever air spring, especially relates to a kind of rigid locking adjustable lever air spring of overlength stroke.
Background technique
Traditional rigid lock adjustment bar air spring is used widely in all trades and professions at present, and its structure is seen Fig. 1, comprising: push rod 1 ', piston rod 2 ', cylinder barrel 3 ', little moveable door 4 ', piston 5 ', separator piston 6 '.Working principle is: in cylinder barrel 3 ', inject hydraulic oil, and by separator piston 6 ' pressurized gas and hydraulic oil are isolated.Gas pressure intensity acts on separator piston 6 ', and process hydraulic oil is transmitted to the both ends of the surface of piston 5 ', by the difference in areas of rod chamber and rodless cavity, forms the thrust output of piston rod 2 '.When little moveable door 4 ' was closed, piston 5 ' two ends hydraulic oil were not connected, and the adjustable lever air spring is in locking state; Open little moveable door 4 ' when promoting push rod 1 ' to the right; At this moment, piston 5 ' two ends hydraulic oil intercommunications, the adjustable lever air spring is in open mode; Piston rod 2 ' drives piston 5 ' and externally moves right under the thrust, or under the internal pressure effect, is moved to the left.
As can beappreciated from fig. 1, its working stroke of traditional rigid lock adjustment bar air spring directly depends on the length of piston rod 2 ' and the length of valve push rod 1 '.At present, the external diameter of traditional rigid lock adjustment bar air spring piston rod is generally 8mm-12mm, and the internal diameter of piston rod is 4mm, and the valve push rod external diameter is 4mm.When the stroke overlength of air spring, the difficulty of processing of elongated orifices piston rod and cost all will sharply increase, and valve push rod length receives the influence of linarity and rigidity when surpassing certain limit, can not accomplish the proper functioning of backing down valve.
Summary of the invention
In order to overcome the above-mentioned deficiency of conventional rigid lock adjustment bar air spring, the utility model provides a kind of overlength stroke rigid locking adjustable lever air spring of brand new.The piston rod that it can become rigid locking adjustable lever air spring becomes solid stock by the hollow thin stock; Valve push rod no longer passes through the piston rod center, thereby the stroke of realizing air spring is not limited by conventional construction piston rod inner elongate center hole processing restriction and the elongated valve push rod linearity and the not enough restriction of rigidity.
The technological scheme of the utility model is; A kind of overlength stroke rigid locking adjustable lever air spring, it comprises: push rod, piston rod, cylinder barrel, little moveable door, piston, separator piston is characterized in that: in cylinder barrel, set up an inner cylinder tube; Said piston and piston rod are arranged on an end of inner cylinder tube; Valve body and said push rod are arranged on the other end of inner cylinder tube, and said little moveable door is installed on the valve body, can in said valve body, move.
Further, piston rod adopts solid construction.
Further, the stroke of adjustable lever air spring can be the overlength stroke.
The beneficial effect of the utility model is: because the design of brand new, little moveable door is installed in the valve body, opens and closes through the passage that control valve body is inner, controls the locking of air spring and opens.Push rod need not pass through the middle part of piston rod and remove the top little moveable door, and the stroke of its structure length and air spring is irrelevant.Therefore, the piston rod of this kind structure can be made the solid piston bar that is easy to process, thereby realizes adjustable lever air spring not only overlength stroke but also rigid locking.
Description of drawings
Fig. 1 is the structural representation of traditional rigid lock adjustment bar air spring.
Fig. 2 is the structural representation of the overlength stroke rigid locking adjustable lever air spring of the utility model.
Embodiment
As shown in Figure 2; A kind of overlength stroke rigid locking adjustable lever air spring of the utility model comprises: push rod 1, piston rod 2, cylinder barrel 3, little moveable door 4, piston 5, separator piston 6; In cylinder barrel 3, set up an inner cylinder tube 8, piston 5 and piston rod 2 are arranged on an end of inner cylinder tube 8, and valve body 7 and push rod 1 are arranged on the other end of inner cylinder tube 8; Little moveable door 4 is installed on the valve body 7, can in valve body 7, move.Adopt inside and outside cylinder barrel structure, guaranteed that the adjustable lever air spring still keeps locking rigidity.
Piston rod 2 adopts solid construction.Make the length of piston rod can require any increase according to the stroke to air spring, promptly air spring can be the overlength stroke, and is not limited by conventional construction piston rod inner elongate center hole processing restriction and elongated valve push rod linarity and the not enough restriction of rigidity.
Its working principle is: separator piston 6 is kept apart pressurized gas and hydraulic oil between inner cylinder tube 8 and the cylinder barrel 3, guarantees that inner cylinder tube 8 inside are full of hydraulic oil.Gas pressure intensity acts on separator piston 6, and process hydraulic oil is transmitted to the both ends of the surface of piston 5, by the difference in areas of rod chamber and rodless cavity, forms the thrust output of piston rod 2.Little moveable door is installed on the valve body 7 for 4 this moments, and the open and close of the inner passage of control valve body 7.When little moveable door 4 was closed, the inner passage on the valve body 7 was closed, and the hydraulic oil in the inner cylinder tube 8 must not flow, and the adjustable lever air spring is in locking state.Open little moveable door 4 if promote push rod 1 left, at this moment, the inner passage on the valve body 7 is opened.When piston rod 2 externally drove piston 5 under the thrust and moves right, the hydraulic oil in the inner cylinder tube 8 flowed to the space of formation between cylinder barrel 3 and the inner cylinder tube 8 through the passage in the valve body 7; When under pressure action, when piston 5 drive piston rods 2 were moved to the left, the passage of hydraulic oil in valve body 7 flowed back to the inside of inner cylinder tube 8 again.Guaranteed the rigid locking of adjustable lever air spring when little moveable door 4 is closed, and when little moveable door 4 is opened, the moving freely of piston rod.
Because the little moveable door 4 of the overlength stroke rigid locking adjustable lever air spring of brand new is installed in the valve body 7, and opens and close, control the locking of air spring and open through control valve body 7 inner passages.Owing to little moveable door 4 no longer need be along with the displacement of piston 5 be moved, push rod 1 need not pass through the middle part of piston rod yet and remove top little moveable door 4, and the stroke of its structure length and air spring is irrelevant.Therefore, the piston rod of this kind structure just can be made the solid piston bar that is easy to process, and realizes overlength stroke rigid locking adjustable lever air spring.
