Said elastic device is an annular gasket.
Offer several roughly Y-shaped holes on its circumferential direction of said annular gasket upper edge; Three sections of this hole are all curved; And all concentric with annular gasket, away from the radian of the segmental arc in the hole in the center of circle greater than near excessively semicircle between the radian of the segmental arc in the hole in the center of circle and this two segmental arc.
Offer three roughly Y-shaped holes on its circumferential direction of said annular gasket upper edge.
Said groove is a kidney slot.
Said driven hanging apparatus comprises that rotating the weak point that the minor axis in the pedestal is set and links to each other with minor axis overlaps, and short cover is positioned at the pedestal downside.
The beneficial effect of the utility model is: the quality change when the crystal production gear of said structure can be monitored crystal growth automatically; And crystalline rotation and do not move up and down and can influence its monitoring effect; The rotation of lift shaft simultaneously realizes that through the promotion of ball when lift shaft was blocked, ball was extruded by force from the groove of lift shaft; Make lift shaft lose motivating force, avoid lift shaft to rotate and cause the device damage by force.

Embodiment
Below in conjunction with accompanying drawing, describe the specific embodiments of the utility model in detail.
As shown in Figure 1; The described a kind of device that is used to monitor crystal growth of the utility model; Comprise that support 1 and the lift shaft 2, the support 1 interior top that are arranged in the support 1 are provided with LOAD CELLS 3; The lower end of said LOAD CELLS 3 is set with pedestal 4, rotates in the pedestal 4 and is provided with driven hanging apparatus.Driven hanging apparatus comprises that rotating the weak point that the minor axis 5 in the pedestal 4 is set and links to each other with minor axis through bearing overlaps 6, and short cover 6 is positioned at pedestal 4 lower ends.When actual production, minor axis 5 also can be one-body molded with weak point cover 6.The upper end of lift shaft 2 is arranged on through bearing and is provided with in the short cover 6.Be arranged with drive sleeve 7 on the lift shaft 2, and the upper end of drive sleeve 7 is positioned at short cover 6 outsides, and is fixedly linked through elastic device between the upper end of drive sleeve 7 and the short cover 6.Because the device that the utility model is used to monitor crystal growth when mounted; Drive sleeve 7 has small skew in vertical direction with short cover 6; And installation dimension is fixed, and can offset the influence of squinting and bringing so link to each other through elastic device between the upper end of drive sleeve 7 and the short cover 6.As shown in Figure 2, elastic device can be annular gasket 8.The preglabellar field of annular gasket 8 is fixedly connected with the outer wall of short cover 6, and the outward flange of annular gasket 8 is fixedly connected with the inwall of drive sleeve 7.Offer several roughly Y-shaped holes 9 on its circumferential direction of said annular gasket 8 upper edges; Three sections of this hole 9 are all curved; And all concentric with annular gasket 8, away from the radian of the segmental arc in the hole 9 in the center of circle greater than near excessively semicircle between the radian of the segmental arc in the hole 9 in the center of circle and this two segmental arc.When actual production, the quantity in hole 9 can require to set according to reality.The drive unit (because of prior art, not shown) that the lower end of drive sleeve 7 passes from support 1 and rotates in the driven drive sleeve that is positioned at support 1 outside 7 links to each other.As shown in Figure 3; The outer surface portions that said lift shaft 2 is positioned at short cover 6 axially is provided with kidney slot 10 along lift shaft 2, is provided with ball 11 in the kidney slot 10, and short cover 6 is provided with spring 12; One end of this spring 12 is against ball 11 in the kidney slot 10, and the lower end of lift shaft 2 also passes in support 1.
The working process of the utility model is: because in crystal pulling method and rotational method; Crystal needs rotation and moves up and down in the crystalline process; So utilizing drive unit to drive drive sleeve 7 rotates; Drive sleeve 7 drives short cover 6 through annular gasket 8 and rotates, and short cover 6 drives minor axis 5 again and in pedestal 4, rotates, and LOAD CELLS 3 is not influenced by the rotation of minor axis 5 when measuring crystal weight.Simultaneously, short cover 6 also drives lift shaft 2 through the ball 11 that is propped up by spring 12 and rotates, and along with the rotation of lift shaft 2, the crystal that hangs over lift shaft 2 lower ends also begins to rotate.Crystalline moves up and down then through moving up and down the device and the drive unit that are used to monitor crystal growth and realizes.In the above-mentioned working process, LOAD CELLS 3 is unaffected, can well monitor the crystalline weight change, thereby to crystallization condition a good reference is provided.If in operating process, the crystal of the lower end of lift shaft 2 rotates when being obstructed because of running into crucible, can by force ball 11 be extruded from kidney slot 8, avoid lift shaft 2 by drive sleeve 7 by force driven rotary and cause crystal damage or whole device impaired.
