Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, the utility model comprises fixed slider 6, movable slider 7, mandrel 3, location slip ring 1, locking screw 11 and dog screw 12.For easy for installation, be provided with fixed slider open holes 8 at fixed slider 6 peripheries, fixed slider 6 is installed on the three-dimensional micro-motion platform base of micromanipulator by fixed slider open holes 8 with screw.The vertical section of movable slider 7 is T-shape, and its underpart is minor axis; Offer through hole on the axis of minor axis, the periphery of minor axis is arranged with concentric location slip ring 1; Offer radially screw on the slip ring 1 of location, dog screw 12 radially is installed in the screw; Also be provided with the movable slider open holes at movable slider 7 peripheries, movable slider 7 be installed on the three-dimensional micro-motion platform of micromanipulator by the movable slider open holes with screw.The bottom of mandrel 3 is anchored on the fixed slider 6, and the top of mandrel 3 places in the through hole of movable slider 7 minor axises, and mandrel 3 and minor axis through hole are concentric(al) circles; For strengthening self-lubricating and the wear-resisting effect of fixed slider 6 and movable slider 7 contact surfaces, at the end face covering teflon gasket 2 of movable slider 7 minor axises; The steadiness that is connected by mandrel 3 for strengthening fixed slider 6 and movable slider 7 adds catch 5 in the through hole outside of movable slider 7 end faces, mandrel screw 4 is passed catch 5 be screwed in mandrel 3 threaded holes.Fixed slider 6 one ends are installed locking screw nail seat 9, and further, locking screw nail seat 9 is installed on the fixed slider 6 by locking screw nail seat mounting screw 10, and self-locking screw base 9 outsides are screwed into locking screw 11.
During installation, at movable slider 7 minor axis peripheries cover location slip ring 1, cover teflon gasket 2 at movable slider 7 short shaft end faces first.Then the bottom with mandrel 3 is anchored on the fixed slider 6, and the top of mandrel 3 placed in the through hole of movable slider 7 minor axises, after the through hole outside of movable slider 7 end faces adds catch 5, mandrel screw 4 is passed catch 5 to be screwed in mandrel 3 threaded holes, movable slider 7, location slip ring 1 and fixed slider 6 are connected as a single entity, and each other can be freely, smoothly rotation.Radially be screwed into dog screw 12 in the screw at location slip ring 1 again, only need screw dog screw 12, location slip ring 1 can be fixed on the minor axis of movable slider 7.By locking screw nail seat mounting screw 10 locking screw nail seat 9 is installed at fixed slider 6 at last, screws in locking screw 11 from locking screw nail seat 9 one ends, only need screw locking screw 11, fixed slider 6 and the relative position of movable slider 7 can be fixed.Thereby finish the combination that micromanipulator is used the rotary locating device of biaxial type.
In the process that reality is used, at first connect fixed slider 6 and the three-dimensional micro-motion platform base of cell micromanipulator with screw by fixed slider open holes 8, connect movable slider 7 and the three-dimensional micro-motion platform of cell micromanipulator with screw by the movable slider open holes.Movable slider 7 is put to the working position, unscrew dog screw 12, make location slip ring 1 and movable slider 7 compositions from state, rotation location slip ring 6, one end of locking screw nail seat 9 is served as a mark a little, when dog screw 12 is close to locking screw nail seat 9 one end, screw dog screw 12, make 7 one-tenth connection state of location slip ring 1 and movable slider, screw simultaneously locking screw 11, movable slider 7, location slip ring 1 and fixed slider 6 are connected as a single entity, can form the working position locating point, as shown in Figure 3.When needs are changed patch clamp electrode or microneedle, only need the Z axis platform of the three-dimensional micro-motion platform of cell micromanipulator is mentioned, make patch clamp electrode or microneedle break away from cell, unscrew locking screw 11, dog screw 12 is motionless, rotation movable slider 7 is then located slip ring 1 and the rotation of movable slider 7 one, can change easily patch clamp electrode or microneedle.Change complete after, with movable slider 7 cycle locating points, namely when dog screw 12 is close to locking screw nail seat 9 one end, screw locking screw 11, put down again the Z axis platform of the three-dimensional micro-motion platform of cell micromanipulator, this moment, patch clamp electrode or microneedle namely were positioned at the position before changing, and did not affect the continuity of test operation and the accuracy of work point.
In addition, mounting means and the position of this device on the display operation device is very flexible, is widely used, and is not limited to the listed mounting means of embodiment and position, also is adapted to the mechanism that other need to rotate the location.
