Abstract

The utility model relates to a magnetic shock absorber, comprising an upper part and a lower part, wherein, the upper part comprises an object bearing platform (1) positioned at the top, an upper shielding shell (2) which is shaped like a reverse Chinese character ''ao'' and is clung to the bottom surface of the object bearing platform (1) tightly, and an upper magnet (3) arranged in the groove of the upper shielding shell (2); the lower part comprises a base (5) arranged at the bottom, a lower shielding shell (6) which is shaped like a Chinese character ''ao'' and is clung to the upper surface of the base (5), and a lower magnet (7) arranged in the groove of the lower shielding shell (6); the polarity of the bottom surface of the upper magnet (3) is the same as the polarity of the upper surface of the lower magnet (7); certain distance is arranged between the upper part and the lower part due to repulsive force; a left positioning column (8) and a right positioning column (4) are inserted in the positioning holes on the corresponding sides of the object bearing platform (1) and the base (5). The utility model has the advantages of no need of maintenance and replacement, long service life, high sensitivity, low cost and wide application range.

Description

The magnetic vibration reducing device

Technical field

The utility model relates to a kind of vibration damper.

Background technique

Existing vibration damper is mostly made with metal spring, and metal spring is not suitable in extreme environments such as water medium and high temperature, high and cold, high pH value and uses, and it is not antirust, corrosion resistant, not low temperature resistant not.

Summary of the invention

The purpose of this utility model will provide a kind of Maintenance free, replacing, the life-span is long, highly sensitive, cost is low, purposes is wide magnetic vibration reducing device.

The technical solution of the utility model is achieved like this: a kind of magnetic vibration reducing device, be characterized in: it is made up of upper and lower two parts, top comprises the bearing table 1 that is positioned at the top, be close to the bearing table bottom surface fall shielding case 2 on " recessed " font, place the upper magnet 3 of the groove of shielding case 2; The bottom comprises the base 5 that is positioned at the bottom, be close to shielding case 6 under " recessed " fonts of base 5 upper surfaces, place down the lower magnet 7 of the groove of shielding case 6; The bottom surface of upper magnet 3 is identical with the polarity of lower magnet 7 upper surfaces, between top and the bottom because of repulsive force at a distance of certain distance, in bearing table 1 and base 5 corresponding both sides positioning holes, be inserted with left and right locating column 8 and 4.

Because the utility model is to utilize two magnets of former reason that the same sex repels each other to constitute, thus low cost of manufacture use down applicable to extreme environment, as under the water medium and high temperature, high and cold under, use in the high pH value environment, it is antirust, corrosion resistant, high-low temperature resistant; Because magnet is permanent magnetism, thus this vibration damper Maintenance free, replacing, life-span long, highly sensitive it can satisfy the demand (through preventing not having influence to external world after the magnetic treatment) of high-accuracy occasion.

Embodiment

From Fig. 1 as seen, this magnetic vibration reducing device divides upper and lower two-part to form, and the top on top is a bearing table 1, and the bearing table bottom surface is glued with down shielding case 2 on " recessed " font, is built-in with upper magnet 3 at last shielding case groove; The bottom of bottom is a base 5, be glued with shielding case 6 under " recessed " font at base 5 upper surfaces, groove at following shielding case 6 is built-in with lower magnet 7, the top of lower magnet 7 is identical with the below polarity of upper magnet 3, is all " S " utmost point or " N " utmost point, because the same sex is repelled each other, there is certain space between the upper and lower part, size distance between the two according to external force pressure on the bearing table changes thereupon,, thus play the buffering and the good result of damping.In the both sides positioning hole of bearing table 1 and base 5 correspondences, be inserted with left and right locating column 8 and 4.The last lower magnet of this device can be square or circular.

Claims

1, a kind of magnetic vibration reducing device, it is characterized in that: it is made up of upper and lower two parts, top comprises the bearing table (1) that is positioned at the top, be close to the bearing table bottom surface fall shielding case (2) on " recessed " font, place the upper magnet (3) of the groove of shielding case (2); The bottom comprises the base (5) that is positioned at the bottom, be close to shielding case (6) under " recessed " font of base (5) upper surface, place down the lower magnet (7) of the groove of shielding case (6); The bottom surface of upper magnet (3) is identical with the polarity of lower magnet (7) upper surface, between top and the bottom because of repulsive force at a distance of certain distance, in bearing table (1) and the corresponding both sides of base (5) positioning hole, be inserted with left and right locating column (8) and (4).

2, a kind of magnetic vibration reducing device according to claim 1, it is characterized in that: described upper and lower magnet is a square structure.
