Abstract
The utility model relates to a controllable air-powered power storing lifting machine which is equipment used for supporting articles of seat backrest. The utility model is mainly composed of a front ejecting sleeve, a control valve seat, a control valve core, an internal pipe, an external pipe, a plunger, sealing rings, a piston rod, a piston rod seat, a lubricating felt, a rear axle housing and a supporting sleeve. The utility model is characterized in that both end surfaces of the plunger are respectively provided with a V-shaped groove; three sealing rings are arranged between the internal pipe and the external pipe; four movable sealing rings are arranged between an oil seat and the valve core; the lubricating felt is dealt by soaking in oil; tetrafluoroethylene material is adopted in the supporting sleeve. The diameters of one end surface of the control valve core are respectively 8.5 mm and 6 mm. The utility model has the advantages of controllable stroke, convenient operation, safety, durability and reliability.
Description
What the utility model provided is a kind of support seat back equipment---the pneumatic accumulation of energy lift device of controllable type.
Prior art, as CN90209427.0, CN91208083.3, the former major character is that oil guide pipe one end and piston join.The other end slips under the lubricant oil liquid level, thereby makes the movable sealing structure of controlled air spring can obtain lubricated fully.The latter's major character is to be provided with the oil gas separator mutually closely connected with cylinder inboard wall in cylindrical shell, and oil and high pressure air are separated.Above-mentioned two kinds of common defectives are to need two kinds of media, thus complex structure, manufacture cost height, stroke limiting system.
The purpose of this utility model is the problem at above-mentioned existence, and it is adjustable to propose a kind of stroke, and is easy and simple to handle, safe and reliable, the pneumatic accumulation of energy lift device of durable controllable type.
Technical solution of the present utility model: structure as shown in drawings.Form by sinciput cover 2, control valve seat 3, control spool 4, piston 6, seal ring 13, piston rod 7, piston pole socket 9, rear axle housing 11, supporting sleeve 12 two ends end sockets.The circulation plenum chamber that is provided with is made up of interior pipe 5, outer tube 8, the outside of pipe 5 in outer tube 8 is provided in a side of, biend at piston 6 respectively is provided with a V-shaped groove, between interior pipe 5 and outer tube, be provided with three static seal circles, four dynamic seal rings are located between control spool and control valve seat, inner chamber at control valve seat 3 has three seal grooves, control spool 4 big end surface are established an O RunddichtringO, and the endoporus that pushes up cover 11 in the back is provided with lubricating felt of handling through immersion oil 10 and the supporting sleeve 12 that adopts the tetrafluoroethylene material to make.The Outside diameter of control spool 4 is 8.5mm, and end diameter is 6mm.
Accompanying drawing is a structural representation of the present utility model
1 is switch axle, the 2nd among the figure, sinciput cover, the 3rd, control valve seat, the 4th, control spool, the 5th, interior pipe, the 6th, piston, the 7th, piston rod, the 8th, outer tube, the 9th, piston pole socket, the 10th, lubricating felt, the 11st, top, back cover, the 12nd, supporting sleeve, the 13rd, seal ring.
Provide their working procedure below in conjunction with accompanying drawing.
Outer tube 8 carries out seal isolation with interior pipe 5 by control valve seat 2 and piston pole socket 9 and piston rod 7 usefulness O RunddichtringOs, and inner chamber is full of pressurized gas and a certain amount of lubricant oil, because interior pipe 5 inner chamber air pressure force control spool 4 to be in closed condition all the time.Tube cavity and outer tube bore store pressurized gas by inside and outside the pipe in small stair and 1 aperture of the interior pipe the other end form in the middle of aperture in the control valve seat and the control spool in when applied force promotes the control spool, piston 6 left and right sides air-flows are ganged up, at this moment because the side face of piston ring product moment forces the piston rod elongation, as long as when moving to Len req, unclamp the control spool, because air pressure forces spool to be closed automatically in the interior pipe, piston rod 7 promptly is locked on the given location, this moment, piston rod 7 can bear required buffer load, (required load is according to the inner chamber inflation pressure), otherwise as wanting, be in open mode as long as promote the control spool, outer tube applies a little external force again, piston rod 7 shortens thereupon, loosens the control spool and promptly is in closed condition, and piston rod is by lock control.
Advantage of the present utility model:
Improved the Pneumatic lifting/lowering device sealing reliability. Because improving the sealing of piston 5, material structure improves 3.5 times with wearability than other material. Haul distance can increase 5～8 times. Not limited by any direction. Reliability and durability reaching 100,000 times, the step test performance is intact.
Claims (2)
1, the pneumatic accumulation of energy lift device of controllable type, by sinciput cover 2, control valve seat 3, control spool 4, piston 6, seal ring 13, piston rod 7, piston pole socket 9, rear axle housing 11, supporting sleeve 12 two ends end sockets are formed, it is characterized in that the circulation plenum chamber that is provided with is a pipe 5 in having, outer tube 8 is formed, the outside of pipe 5 in outer tube 8 is provided in a side of, biend at piston 6 respectively is provided with a V-shaped groove, between interior pipe 5 and outer tube, be provided with three static seal circles, four dynamic seal rings are located between control spool and control valve seat, inner chamber at control valve seat 3 has three seal grooves, control spool 4 big end surface are established an O RunddichtringO, and the endoporus that pushes up cover 11 in the back is provided with lubricating felt of handling through immersion oil 10 and the supporting sleeve 12 that adopts the tetrafluoroethylene material to make.
2, the pneumatic accumulation of energy lift device of controllable type according to claim 1, the Outside diameter that it is characterized in that controlling spool 4 is 8.5mm, end diameter is 6mm.
