Abstract
The utility model discloses a magnetic force buffer, comprising a pair of strong magnets, a guiding plunger piston, a guiding sleeve and a columnar cylinder; wherein, the pair of strong magnets are positioned in the columnar cylinder in opposite, one magnet is arranged on the bottom of the columnar cylinder, the other magnet is arranged on the end of the guiding plunger piston in the columnar cylinder, and the magnetic pole of the adjacent ends of the two magnets are same; the guiding sleeve is arranged on the upper part in the columnar cylinder, and the guiding plunger piston can slide in the guiding sleeve. Owing to the adoption of the technical theory of static magnetic repulsion, the utility model has the advantages of simple structure, low cost, good damping and buffering effect, and long service life.
Description
One, technical field
The utility model relates to a kind of magnetic buffering device.
Two, background technique
Magnet (permanent magnet or electromagnet) is divided into N, S the two poles of the earth, repels mutually between the homopolarity, attract each other between the heteropole, and be the natural law of everybody knows.But, really this character is applied in the engineering reality, how long but do not have.And the overwhelming majority is used and still to be conceived to the characteristic that attracts each other between the heteropole.For example, magnetic force shaft joint, magnetic seal etc.Magnetic suspension train is that homopolar-repulsion character is used for one of industrialized less example of seeing, belongs to dynamic magnetic repulsion technology.
Buffer also has multiple, mostly is liquid (gas) greatly and presses buffering, spring buffer and the synergy of liquid (gas) pressing spring etc.Liquid (gas) compression buffer has the cost height, seal failure causes defectives such as dielectric leakage, maintenance cost height easily, and the defective of bullet is lost in spring buffer existence meeting because of spring fatigue.
Three, model utility content
Goal of the invention of the present utility model is to overcome the defective that prior art exists, and utilizes static-magnetic repulsion know-why, and a kind of magnetic buffering device is provided.
The utility model magnetic buffering device is made of a pair of strong magnets, pilot spool, guide sleeve and cylindrical barrel body; Wherein a pair of strong magnets is staggered relatively in cylindrical barrel body, and one is arranged on the cylindrical barrel body inner bottom part, and another piece is arranged on the end that pilot spool is positioned at cylindrical barrel body, and the end magnetic pole that two blocks of magnet is adjacent is identical; Guide sleeve is arranged at the cylindrical barrel body internal upper part, and pilot spool can slide in guide sleeve.
Another technological scheme of the utility model magnetic buffering device is basic identical in such scheme, and different is that described cylindrical barrel body is magnetic conduction not.
The utility model magnetic buffering device is owing to adopt static-magnetic repulsion know-why, and is simple in structure, cost is low, damping, buffering is effective, long service life.
Four, description of drawings
Fig. 1 is the utility model magnetic buffering device structural representation.
Five, embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As Fig. 1, the utility model magnetic buffering device is made of the cylindrical barrel body 4 of a pair of strong magnets 1, pilot spool 2, guide sleeve 3 and plexiglass material; Wherein a pair of strong magnets is staggered relatively in cylindrical barrel body 4, and one is arranged on cylindrical barrel body 4 inner bottom parts, and another piece is arranged on the end that pilot spool 2 is positioned at cylindrical barrel body 4, and the end magnetic pole that two blocks of magnet is adjacent is identical; Guide sleeve 3 is arranged at cylindrical barrel body 4 internal upper parts, and pilot spool 2 can slide in guide sleeve 3.
In the practicality, when external force acted on the upper end of pilot spool 2, pilot spool moved downward, and under the effect of strong magnetic repulsion, the downglide motion of pilot spool 2 stops gradually, thereby plays the bumper and absorbing shock effect.
Claims (2)
1, a kind of magnetic buffering device, constitute by a pair of strong magnets (1), pilot spool (2), guide sleeve (3) and cylindrical barrel body (4), it is characterized in that: a pair of strong magnets (1) is staggered relatively in cylindrical barrel body (4), one is arranged on cylindrical barrel body (4) inner bottom part, another piece is arranged on the end that pilot spool (2) is positioned at cylindrical barrel body (4), and the end magnetic pole that two blocks of magnet is adjacent is identical; Guide sleeve (3) is arranged at cylindrical barrel body (4) internal upper part, and pilot spool (2) can slide in guide sleeve (3).
2, magnetic buffering device according to claim 1 is characterized in that: described cylindrical barrel body (4) is magnetic conduction not.
