Description
Technical field
The present invention relates to magnetic suspension tellurian technical field, in particular to a kind of magnetic suspension tellurians being easily installed.
Background technology
Magnetic suspension tellurian is the tellurion using magnetic levitation technology, and different from common tellurion, it is passed through without shaft
Sphere can be suspended in the air, more vividly really present form of the earth in space, had very high appreciation and made
The property used.Magnetic suspension tellurian in the prior art includes mainly sphere and pedestal, and operation principle is as follows：Magnetic there are one being set in sphere
Iron, pedestal is interior to be equipped with wire coil, control circuit board and Hall detector, and wire coil will become electromagnet by electric current,
Repulsive force between electromagnet and sphere internal magnet can offset gravity suffered by tellurion, therefore tellurion floatability is used in the air
Hand gently touches tellurion and causes a deviation from equilbrium position, and hand removes rear tellurion still and can return to that equilbrium position is unlikely to be fallen, Hall
Detector can detect the changes of magnetic field of sphere internal magnet, and when sphere deviates equilbrium position, Hall detector detects magnet
Changes of magnetic field will generate a compensation electric current, and when compensation electric current flows to wire coil, wire coil magnetic field increases, can be by the earth
Instrument retracts equilbrium position.
There is no any ancillary equipment between sphere and pedestal in the prior art, is indicated without specific installation site, ball
The distance between body and pedestal need artificial control, and installation is relatively difficult, when installation site deviates, are susceptible to sphere and pedestal
The phenomenon that being sucked suddenly, finger can be clamped damage at this time, so structure in the prior art not only installs inconvenience, peace
Full performance is also relatively low.
Invention content
The technical problem to be solved by the present invention is to overcome the above technological deficiency, provides and a kind of facilitate installation, security performance high
Magnetic suspension tellurian.

To pedestal.
The advantages of the present invention over the prior art are that：When mounted, Sphere orientation axis can be made to stretch by driving mechanism
Go out, directly sphere can be located on Sphere orientation axis when placing sphere, or placed by object of reference of Sphere orientation axis, is put
Sphere orientation axis is retracted to base interior again after the completion of setting, such structure does not need user and slowly adjusts searching sphere and pedestal
Between equilibrium distance, installation speed is fast, easy to use, and security performance is high.
As an improvement, Sphere orientation axis upper end be moved to balance of the distance outside pedestal between sphere and pedestal away from
From the height that Sphere orientation axis stretches out is that sphere is directly placed on by the equilibrium distance between sphere and pedestal without adjusting
Sphere orientation axis, quick and precisely.
As an improvement, the pedestal includes mutually matched upper shell and lower housing, it is between upper shell and lower housing
Be detachably connected, upper-lower casing structure facilitates the installation of whole device all parts, be detachably connected relationship it is easy to disassemble and dimension
It repaiies.
As an improvement, the middle handle is hinged in pedestal, and one end and Sphere orientation axis connection, the other end are stretched
Go out to pedestal, is directly the position of adjustable Sphere orientation axis in external pressing handle, it is easy to operate.
As an improvement, the Sphere orientation axis is the cylindrical structure with ring baffle, the pedestal is equipped with
With the matched through-hole of cylinder, set is equipped with spring on Sphere orientation axis, and one end of Sphere orientation axis and handle are hinged, annular
Baffle plays the position-limiting action to Sphere orientation axis, and the diameter of ring baffle is more than the diameter of through-hole, and the setting of spring can make ball
Body locating shaft automatically resets, overall structure simple and compact, and using effect is good.
As an improvement, being equipped with handle fixed frame in the pedestal, it is convenient for fixed handle.
As an improvement, the driving mechanism includes motor, the motor is located in pedestal, and motor is electrically connected with pcb board component
It connects, and is equipped with changement between motor and Sphere orientation axis and is sequentially connected；The pedestal is equipped with to be slided with Sphere orientation axis
The through-hole of cooperation；The pedestal is equipped with the control switch of control motor operating；Then in this way after setting, user need to only pass through control
The lifting of control sphere locating shaft can be realized in system switch, and ease of use is more preferable, and whole parts are less, manufacturing cost phase
To relatively low.
As an improvement, the changement includes screw rod, the output axis connection of the screw rod and motor；The Sphere orientation
The lower end of the nearly motor of axis is equipped with the threaded hole screwed with screw rod；Control switch is by compressing switch or inductive switch；Then screw rod
The structure of lead screw is formed with threaded hole, such simple in structure, manufacturing cost is relatively low, and operation is also relatively steady, and use reliability is good.
As an improvement, the Sphere orientation axis is prismatic structures；Or the Sphere orientation axis is cylindrical structure, sphere
The peripheral surface of locating shaft is equipped with guide pad, and the hole wall of through-hole is equipped with the guide groove being oriented to guide pad cooperation；Then use rib
When column construction, other guiding mechanism is not needed, prepares simplicity, use is also more convenient；And when using cylindrical structure, it is whole
Harmony it is preferable, aesthetics is good.
As an improvement, the end of the Sphere orientation axis is to make sphere with the matched globoidal structure of sphere, such structure
Facilitate placement and sphere will not roll sideslip.
