Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described:
As shown in Figure 1, Figure 2 and Figure 3, the gravity adjusting device of chemical experiment iron stand platform of the present invention is mainly made up of fixed platform 1 and the gimbal lever 2, the middle part of fixed platform 1 is provided with mean for the through hole 11 of pillar 3 traverse of chemical experiment iron stand platform, being provided with four symmetrical semicolumns outside through hole 11, each semicolumn is provided with a pin hole 12; The gimbal lever 2 is L-shaped, its short section is provided with rotation latch 22, rotation latch 22 is inserted in the pin hole 12 of fixed platform 1, make the rotation that the gimbal lever 2 can make 180 degree around fixed platform 1, the long section of the gimbal lever 2 and the pillar 3 of chemical experiment iron stand platform are mutually perpendicular to, being socketed with balancing weight 23 in the long section of the gimbal lever 2, its outboard end is provided with lock nut 21, to prevent balancing weight 23 landing. The semicolumn side of fixed platform 1 is respectively equipped with the fixed screw 14 that can stretch into pin hole 12 top pressure rotation latch 22, is provided with the lock screw 13 that can stretch into through hole 11 top pressure pillar 3 between two semicolumns.
In order to prevent balancing weight 23 from rotating, the long section of the gimbal lever 23 is set to square structure, and the balancing weight 23 being socketed with it is also correspondingly provided with the square opening 231 mated.
During use, the through hole 11 of fixed platform 1 is enclosed within the pillar 3 of chemical experiment iron stand platform, fixed platform 1 can be slided on pillar, pillar 3 is pressed by lock screw 13 top after sliding into correct position, fixed platform is made to be locked, then the rotation latch 22 of the gimbal lever 2 is inserted in the pin hole 12 of fixed platform 1, and rotate latch 22 by fixed screw 14 top pressure, with fixing rotation latch 22, again balancing weight 23 is enclosed within the gimbal lever 2, finally lock nut 21 is screwed in the outboard end of the gimbal lever 2. The present invention passes through the turned position of adjustment bar 2 and the socket position of balancing weight 23, and to realize regulating the center of gravity of chemical experiment iron stand platform, balancing weight 23 can increase as required or deduct its weight or quantity.
The concrete operations of apparatus of the present invention are as follows:
When have no occluder in center of gravity point of adjustment, the pillar 3 of chemical experiment iron stand platform, when operating instrument, is first inserted the through hole 11 in fixed platform 1, fixed platform 1 moves to the position of needs, rotational lock screw 13, tightens fixing by operator. The latch 22 that rotates of the gimbal lever 2 is inserted the pin hole 12 in fixed platform 1, the gimbal lever 2 is rotated to the position needed for the center of circle with pin hole 12 in the horizontal plane, tightens fixed screw 14, make the position of the gimbal lever 2 fix. Turn on the lock nut 21 of the gimbal lever 2 outboard end, as desired, by the square opening 231 at balancing weight 23 center by one or more balancing weight 23 fit on gimbal lever 2, and tighten lock nut 21 to prevent balancing weight 23 from undesirably falling off, constantly regulate the center of gravity of iron stand by self-balanced upper rotary 23 until balancing.
When center of gravity point of adjustment has shelter, first the pillar 3 of chemical experiment iron stand platform is inserted the through hole 11 in fixed platform 1, fixed platform 1 is moved to the position of needs, rotational lock screw 13, tightens fixing. The latch 22 that rotates of the Liang Zhi gimbal lever 2 is inserted the pin hole 12 in fixed platform 1, the Liang Zhi gimbal lever lays respectively at the right and left of shelter, respectively the Liang Zhi gimbal lever 2 is rotated with pin hole 12 for the center of circle in the horizontal plane to the position needed, the angle that the left and right Liang Zhi gimbal lever is formed in the horizontal plane with shelter respectively to keep consistent, tightening fixed screw 14, the position of the Shi Liangzhi gimbal lever 2 is fixed respectively. Turn on the lock nut 21 of the Liang Zhi gimbal lever 2 outboard end respectively, as desired, by the square opening 231 at balancing weight 23 center by one or more balancing weight 23 respectively fit on Liang Zhi gimbal lever 2, and tighten lock nut 21 to prevent balancing weight 23 from undesirably falling off. The center of gravity of iron stand is constantly regulated until balancing by the balancing weight 23 in the mobile Liang Zhi gimbal lever 2.
According to circumstances, when not needing the gimbal lever, the gimbal lever 2 can be taken off fixed platform 1, it is not necessary to fixed disassembly platform.
When the needs gimbal lever, the branched gimbal lever and balancing weight can being combined and use, the center of gravity of single unit system being reallocated, it is possible to resolve the gimbal lever cannot be adjusted to the problem specifying position owing to instrument hinders, thus reaching optimum balance effect.
The above is presently preferred embodiments of the present invention, according to the thought of the embodiment of the present invention, all has change part in detailed description of the invention and range of application, and the content of this specification should not be construed as limitation of the present invention.
