Description
The utility model relates to a kind of nuclear magnetic resonance spectrometer rotating driving device, is applicable to that the fluid sample rotation of standard merchandise spectrometer drives, and belongs to the nuclear magnetic resonance spectrometer technology.
The sample rotor of nuclear magnetic resonance spectrometer, be to use nuclear magnetic resonance spectrometer to carry out the used critical component of sample analysis test, the rotation of general fluid sample is to blow rotor drive sample by pressurized air to be rotated, the speed of rotation generally at 10Hz between the 30Hz, sample hose is also subsidiary certain vibration.Such sample rotary system is applied in the conventional liquid high-resolution experiment usually, and with the configuration of the commodity wave spectrum spectrometer of standard, Bruker company as Switzerland, the magnetic resonance experimental apparatus that analysis apparatus manufactures such as the Varian company of the U.S. provide all provides this device, and has different size to sell as annex.The sample rotary system of this commercialization is to float rotor and blow the rotor rotation by pressurized air, rotor speed is controlled by air pressure, thereby the rotational stabilization of rotor is poor, and rotating speed is not high and can not accurately control, the postrotational state of sample can not accurately be grasped, and range of application is limited to.
The purpose of this utility model provides a kind of nuclear magnetic resonance spectrometer rotating driving device, and this device can be adjusted the sample rotational speed stably, easily, accurately grasps the motion state of fluid sample rotation.
In order to achieve the above object, the utility model is motionless by the spectrometer fluid sample rotor-support-foundation system that maintains the standard, and increases the rotation that the fluid sample rotating driving device comes the controlling liquid sample on standard spectrometer fluid sample rotor.The utility model is achieved in that sets up a rotor field spider of being made up of bracket, bottom bracket and fixed bar and the concentric support section of sample hose, a sample rotary driving part branch of forming by micromotor, drive link, swingle, micromotor links to each other with drive link by web member, drive link passes fixture central shaft concentric circles, link to each other with the sample swingle by web member again, the other end of sample swingle passes bottom bracket, is deep in the sample hose, and links to each other with stopper in the sample hose.In order to guarantee stable, the rotation with one heart of swingle, drive that fluid sample is in stable rotation status in the sample hose, bracket is made "T"-shaped cylindric, and top external diameter and magnet mouth external diameter coincide, and lower outer diameter and magnet internal diameter are identical, and just in time embed in the magnet.The top of bottom bracket is right cylinder, and its external diameter and magnet internal diameter coincide and just in time embed, and the bottom is a cylinder body, and the internal diameter of its external diameter and standard spectrometer sample rotor coincide and just in time embeds.Upper and lower carriage is connected and fixed with three fixed bars.Vertical in order to guarantee three fixed bars, the corresponding aperture center line of upper and lower carriage and fixture point-blank and all with the parts central axes.
The making separated into two parts of swingle, an end that outside sample hose, is connected, its diameter and drive link equal diameters with drive link, go deep into the rotary driving part branch in the sample hose, its diameter is managed the supporting making of specification per sample, and make the end " protruding " shape, embed in the interior stopper of pipe.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 is a kind of structural representation of nuclear magnetic resonance spectrometer rotating driving device.
Fig. 2 is the cut-open view and the vertical view of bracket.
Fig. 3 is the cut-open view and the vertical view of bottom bracket.
(1)-micromachine among the figure, (2)-electric machine support, (3A), (3B)-web member, (4)-and bracket, (5)-drive link, (6)-fixed bar, (7) fixture, (8)-and bottom bracket, (9)-swingle, (10)-rotor, (11)-stopper, (12)-and magnet, (4B) be the circular hole of the same ancient cooking vessel shape distribution of three sizes of bracket, (8B) be the round hole of the same ancient cooking vessel shape distribution of three sizes of bottom bracket.
According to Fig. 1, Fig. 2, Fig. 3 as can be known, the internal diameter of the lower outer diameter of bracket (4) and magnet (12) coincide and just in time embeds in the magnet, and its top external diameter is consistent with magnet (12) top external diameter, and whole carriage and magnet are combined into one.The top external diameter of bottom bracket (8) and magnet (12) internal diameter coincide and just in time embed, and the internal diameter of lower outer diameter and rotor (10) coincide and just in time embeds, and bottom bracket and rotor (10) are combined as a whole.Three fixed bars (6) pass bracket (4), fixture (7) by circular hole (4B), pin is gone in the round hole (8B) of bottom bracket (8), and be connected and fixed with bracket (4), fixture (7), the support (2) of support micromotor (1) is screwed the upper bottom surface in bracket (4), drive link (5) passes the center pit of bracket (4) and fixture (7) central axis, its upper end is connected with web member (3A) with the transmission shaft of micromotor (1), and its lower end is connected with swingle (9) by web member (3B).Swingle (9) passes the center pit of bottom bracket (8) central axis, and top links to each other with drive link (5) by web member 3 (B), and the bottom is goed deep in the sample hose, and its end embeds in the interior stopper (11) of pipe.Like this, upper and lower carriage is held together, add driving fit with magnet (12), fixture (7) has guaranteed the firm of fixed bar (6) and drive link (5) again, thereby both reached the stable of sample hose, guaranteed again micromotor (1) when driving specimen holder (9) rotation solution example around the at the uniform velocity rotation of sample hose central shaft.Present embodiment uses on Bruker MSL400 nuclear magnetic resonance spectrometer.
Use this device, simple in structure, easy for installation, easy operating by the control rotating speed of motor, is adjusted the rotational speed of swingle, any rotational speed (as 100Hz) that the sample rotational speed is allowed from 0Hz to the fluid sample, and can accurately grasp the rotation status of fluid sample in the sample hose, widen the range of application of former rice device, particularly can be applicable to the high-resolution and imaging (MRI) research of fluid sample dynamic behaviour.
