Abstract
The utility model relates to the technical field of air springs with high sealing performance, in particular to an air spring with high sealing performance, wherein the air spring is capable of improving the sealing performance. The air spring comprises a steel barrel, a tail block part, a piston rod assembly, a valve assembly and a partition piston, wherein the piston rod assembly is arranged inside the steel barrel, the valve assembly is connected with the piston rod assembly, one end of the steel barrel is connected with the piston rod assembly, the other end of the steel barrel is connected with the tail block part, the other end of the tail block part is provided with a connecting piece, a through hole is formed in the center of the tail block part, and a conical steel needle parallel to the through hole is arranged inside the through hole. The air spring is simple in structure, the steel needle and the through hole are sealed in a plane mode, the air sealing effect is tight, air leakage cannot happen easily, and accordingly the normal operation of the air spring with the high sealing performance is guaranteed.
Description
Technical field
The utility model relates to the technical field of the air spring with high leak tightness, especially a kind of air spring with high leak tightness that can improve sealability.
Background technique
At present, the sealing that the great majority that use on market have between the stifled and steel cylinder of the tail of air spring of high leak tightness is all that steel ball is sealed, there is following shortcoming in such sealing effect: the effect of envelope gas is poor, and easily gas leakage, cause the air spring with high leak tightness normally not use.
The model utility content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, a kind of air spring with high leak tightness that can improve sealability is provided.
The utility model solves the technological scheme that its technical problem adopts: a kind of air spring with high leak tightness, comprise that steel cylinder, tail block up, are arranged on piston rod assembly, the valve component be connected with piston rod assembly and the piston separator in steel cylinder, one end of steel cylinder is connected with piston rod assembly, its the other end is connected with tail is stifled, the stifled the other end of tail is provided with link, the stifled center portion of described tail has through hole, is provided with the taper draw point be arranged in parallel with through hole in through hole.
The diameter of described draw point and the equal diameters of through hole.
The beneficial effects of the utility model are: the utility model is simple in structure, employing face sealing between draw point and through hole, and its envelope gas effect is tight, is difficult for gas leakage, thereby has guaranteed to have the normal operation of the air spring of high leak tightness.
The accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
In figure: 1. steel cylinder, 2. tail is stifled, 21. through holes, 22. taper draw point, 3. piston rod assemblies.
Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
The air spring with high leak tightness as shown in Figure 1, comprise that steel cylinder 1, tail block up 2, are arranged on the piston rod assembly 3 in steel cylinder 1, valve component and the piston separator be connected with piston rod assembly 3, one end of steel cylinder 1 is connected with piston rod assembly 3, its the other end is connected with tail stifled 2, the other end of tail stifled 2 is provided with link, the center portion of tail stifled 2 has through hole 21, is provided with the taper draw point 22 be arranged in parallel with through hole 21 in through hole 21, the equal diameters of the diameter of draw point 22 and through hole 21.
The parallel insertion through hole 21 by taper draw point 22, the seal action that can replace steel ball, taper draw point 22 with respect to the envelope gas better effects if of steel ball, can guarantee to have the air spring normal operation of high leak tightness with through hole 21 formation face sealings, the envelope gas effect of face sealing.
Above-mentioned mode of execution is only explanation technical conceive of the present utility model and characteristics; its purpose is to allow the person skilled in the art can understand content of the present utility model and be implemented; can not limit protection domain of the present utility model with this; all equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed in protection domain of the present utility model.
