Abstract
The utility model provides a pneumatic spring for connecting strokes, having constant size and adjustment pressure, whose pressure adjusting screw sleeve and pressure adjusting piston system are locked by a connecting clip spring, wherein the pressure adjusting screw sleeve is provided with a guide screw and is provided in a special guide slot of back seal in a sliding type, a pressure adjusting screw rod is provided at the inner side of the back seal, the front of the pressure adjusting screw rod is screwed into the internal screw of the pressure adjusting screw sleeve, the pressure adjusting screw rod is clipped by the clip spring at the outer side of the back seal, a pressure adjusting hand wheel is provided on the pressure adjusting screw rod and is screwed and pressed firmly by a connecting fixing screw. The utility model is suitable for large equipments and can be designed according to the stroke and the allowance maximum size of the installment position, the length of the pressure adjusting space is 1/2 or more of the stroke.
Description
Technical field
The utility model relates to a kind of air spring, the constant adjustable in pressure air spring of particularly a kind of stroke Conncetion cimension.
Background technique
Existing a kind of its deficiency of pressure regulation air spring is on the market: 1. can only do the trace adjustment of F1 bearing pressure when low, and be can only raise on former power value basis; 2. it has changed the original stroke of air spring when adjusting.
The model utility content
The utility model provides a kind of stroke Conncetion cimension constant adjustable in pressure air spring.
In order to solve above technical problem, the constant adjustable in pressure air spring of a kind of stroke Conncetion cimension of the present utility model, be connected together and form complete air spring cylinder body by cylinder body and back soldering and sealing, built-in piston and relief piston system in described air spring cylinder body, described piston is connected with fixed piston rod by O type circle and pilot seal system, described relief piston system is connected with the pressure regulation screw mandrel, described pressure regulation silk braid locks by being connected jump ring with the relief piston system, on the pressure regulation silk braid, pacify guide screw, the pressure regulation silk braid is slidably mounted in the specific guiding groove of back envelope, the inside front cover side is debug the silk pressing bar in the back, described pressure regulation screw mandrel front screws in the internal thread of pressure regulation silk braid, the pressure regulation screw mandrel is blocked by jump ring in the envelope outside, back, and the pressure regulation handwheel is positioned on the pressure regulation screw mandrel, is screwed by the connection fastening screw to fasten.
Described relief piston system is made up of back air cavity Sealing and piston seal.
But described relief piston system is positioned at 1/2 pressure regulation travel position the best.
The advantage of above structure is: the utility model is at relatively using on the main equipment, as the mold open of injection machine, and the demoulding discharging of stretcher etc.This air spring can design according to the overall dimensions that required stroke and mounting point allow, the pressure regulation space length to guarantee running length 1/2 or longer.
Description of drawings
Figure is a structural representation of the present utility model.
Embodiment
As shown in the figure, piston rod 4 is built in the cylinder body 5, and with 1 sealing of pilot seal system, piston 2 mounting means O type circles 3, piston rod 4 is to be riveted together with piston 2, cylinder body 5 welds together with back envelope 12 forms complete air spring cylinder body, relief piston system 6 is become one by back air cavity Sealing and piston, pressure regulation silk braid 8 and relief piston system are fitted together, by connecting jump ring 7 lockings, guide screw 9 is positioned on the pressure regulation silk braid 8, adjusts length pressure regulation silk braid 8 can be slided in the specific guiding groove of back envelope 12, pressure regulation screw mandrel 10 is contained in envelope 12 inboards, back, the front screws in the internal thread of pressure regulation silk braid 8, and pressure regulation screw mandrel 10 is blocked by jump ring 13 in envelope 12 outsides, back, and only rotating not can axial motion, pressure regulation handwheel 11 is positioned on the pressure regulation screw mandrel 10, is screwed by connection fastening screw 14 to fasten.Pressure regulation of the present utility model is exactly the size that changes the volume of air cavity, carries out the compression and the amplification of volume on the strong basis of the inflatable chamber level pressure of original per unit volume, has effectively changed the size of internal pressure.But the optimum state of the inflatable chamber of original per unit volume is positioned at 1/2 pressure regulation travel position for well with relief piston system 6, and the internal pressure size is adjusted equal scope is arranged on this position, also can set the highest as required or nil-norm is determined.
Claims (3)
1. constant adjustable in pressure air spring of stroke Conncetion cimension, be connected together and form complete air spring cylinder body by cylinder body and back soldering and sealing, built-in piston and relief piston system in described air spring cylinder body, described piston is connected with fixed piston rod by O type circle and pilot seal system, described relief piston system is connected with the pressure regulation screw mandrel, it is characterized in that: described pressure regulation silk braid locks by being connected jump ring with the relief piston system, on the pressure regulation silk braid, pacify guide screw, the pressure regulation silk braid is slidably mounted in the specific guiding groove of back envelope, the inside front cover side is debug the silk pressing bar in the back, described pressure regulation screw mandrel front screws in the internal thread of pressure regulation silk braid, the pressure regulation screw mandrel is blocked by jump ring in the envelope outside, back, the pressure regulation handwheel is positioned on the pressure regulation screw mandrel, is screwed by the connection fastening screw to fasten.
