Abstract
Provided is a magnetic different-speed damper. The magnetic different-speed damper comprises a rotating shaft (2) and a permanent magnet (1), and is characterized in that two magnets are symmetrically arranged on the left and the right of the permanent magnet (1), the magnet (4) with strong magnetism is arranged on the left of the permanent magnet (1), and the magnet (3) with weak magnetism is arranged on the right of the permanent magnet (1). When the magnetic different-speed damper is used and people use stuff with turning covers, because the permanent magnet (1) has to be separated from the magnets when the magnetic different-speed damper is opened, force can be weakened, and people can easily open the stuff; when the magnetic different-speed damper is closed, high force is needed to open and close the permanent magnet (1) when the permanent magnet (1) repels the same magnetism of the magnet (4) with strong magnetism and the magnet (3) with weak magnetism, and thus a workpiece is well protected.
Description
Technical field
The present invention relates to mechanical engineering field, especially a kind of magnetic friction speed damper, better protecting some things of renovating for people.
Background technology
In existing technology, damper mostly is egg and forces the formula rotary damper, and single arm type rotating shaft requirement on machining accuracy is higher, otherwise in motion process, occur stressed not steadily, application life short phenomenon, also can cause the direct impaired phenomenon of workpiece.
Summary of the invention
The present invention's purpose: propose a kind of magnetic friction speed damper.
In order to realize the purpose of invention, intend by the following technical solutions:
Magnetic friction speed damper of the present invention, a kind of magnetic friction speed damper, structurally at least comprising the annulus circle forms with the rotating shaft that is arranged on annulus circle center, it is characterized in that: at annulus circle inwall, fixed symmetrical strong magnet and weak magnet, fixed a connecting rod in the rotating shaft of described annulus circle center, between permanent magnet in connecting rod one end away from rotating shaft has been fixed permanent magnet, be above-mentioned and strong magnet and weak magnet, the same sex is relative.
The present invention, by the particular design of countershaft body, makes the damping of product further improve, and stability is better, and reliability is higher, and extend application life.
The accompanying drawing explanation
Accompanying drawing has been illustrated structure embodiment of the present invention.
1: permanent magnet; 2: rotating shaft; 3: weak magnet; 4: strong magnet; 5: the annulus circle; 6: connecting rod.
The specific embodiment
Understand and implement the present invention for the ease of those of ordinary skills, below in conjunction with the drawings and the specific embodiments, the present invention being described in further detail.
Magnetic friction speed damper of the present invention, structurally at least comprising annulus circle 5 forms with the rotating shaft 2 that is arranged on annulus circle 5 centers, it is characterized in that: at annulus circle 5 inwalls, fixed symmetrical strong magnet 4 and weak magnet 3, fixed a connecting rod 6 in the rotating shaft 2 of described annulus circle 5 centers, between permanent magnet 1 in connecting rod 6 one ends away from rotating shaft 2 have been fixed permanent magnet 1, be above-mentioned and strong magnet 4 and weak magnet 3, the same sex is relative.
After above-mentioned embodiment; people are when renovating; while opening, because of permanent magnet 1, to separate with kicker magnet 4; power will weaken like this; become very light, but, when closing, permanent magnet 1 is under the mutual same sex of strong magnet 4 and weak magnet 3 is repelled; need larger power to open and close, so just better protected workpiece.
The specific embodiment of the above is better embodiment of the present invention; basis is non-limits the specific embodiment of the invention scope with this; scope of the present invention comprises and is not limited to this specific embodiment, and the equivalence that all shapes according to the present invention, structure are done changes all in protection scope of the present invention.
Claims (1)
1. a magnetic friction speed damper, structurally at least comprise annulus circle (5) and be arranged on the rotating shaft (2) of annulus circle (5) center, it is characterized in that: at annulus circle (5) inwall, fixed symmetrical strong magnet (4) and weak magnet (3), fixed a connecting rod (6) in the rotating shaft (2) of described annulus circle (5) center, between permanent magnet (1) in connecting rod (6) one ends away from rotating shaft (2) have been fixed permanent magnet (1), be above-mentioned and strong magnet (4) and weak magnet (3), the same sex is relative.
