Embodiment
The invention will be further described below in conjunction with the accompanying drawings：
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 by fixed platform 1
Formed with balancing pole 2, the middle part of fixed platform 1 is provided with the through hole 11 passed through for the pillar 3 of chemical experiment iron stand platform, through hole
11 outsides are provided with four symmetrical semicolumns, and each semicolumn is provided with a pin hole 12；Balancing pole 2 is L-shaped, and its is short
Section, which is provided with, rotates latch 22, will rotate latch 22 and inserts in the pin hole 12 of fixed platform 1, enables balancing pole 2 around fixed platform 1
Make the rotation of 180 degree, the length section of balancing pole 2 and the pillar 3 of chemical experiment iron stand platform are mutually perpendicular to, covered in the length section of balancing pole 2
Balancing weight 23 is connected to, its outboard end is provided with lock nut 21, to prevent balancing weight 23 from sliding.The semicolumn side of fixed platform 1
The fixed screw 14 that the top pressure of pin hole 12 rotates latch 22 can be stretched into by being respectively equipped with, and be provided with to stretch between two semicolumns and run through
The lock screw 13 of the top pressure pillar 3 of hole 11.
In order to prevent balancing weight 23 from rotating, the length section of balancing pole 23 is set to square structure, the balancing weight 23 being socketed with it
It is correspondingly provided with the square opening 231 of matching.
In use, the through hole 11 of fixed platform 1 is enclosed on the pillar 3 of chemical experiment iron stand platform, fixed platform 1 can be
Slided on pillar, slide into after correct position by the top pressure pillar 3 of lock screw 13, fixed platform is locked, then
The rotation latch 22 of balancing pole 2 is inserted in the pin hole 12 of fixed platform 1, and latch is rotated by the top pressure of fixed screw 14
22, latch 22 is rotated with fixed, then balancing weight 23 is enclosed on balancing pole 2, lock nut 21 is finally screwed in the outer of balancing pole 2
Side.The present invention is by the turned position of adjustment bar 2 and the socket position of balancing weight 23, to realize regulation chemical experiment
The center of gravity of iron stand, balancing weight 23 can increase or subtract its weight or quantity as needed.
The concrete operations of apparatus of the present invention are as follows：
When have no occluder in center of gravity point of adjustment, operator is when operating instrument, first by chemical experiment iron stand platform
The through hole 11 that inserts in fixed platform 1 of pillar 3, fixed platform 1 is moved to the positions of needs, rotational lock screw 13,
Tighten fixation.The pin hole 12 that the rotation latch 22 of balancing pole 2 is inserted in fixed platform 1, by balancing pole 2 in the horizontal plane with
Pin hole 12 is that the center of circle is rotated to the position of needs, tightens fixed screw 14, fixes the position of balancing pole 2.Turn on balancing pole 2
The lock nut 21 of outboard end, one or more balancing weight 23 is assembled by the square opening 231 at the center of balancing weight 23 on demand
Upper balancing pole 2, and lock nut 21 is tightened to prevent balancing weight 23 from undesirably falling off, pass through the constantly regulate brandreth of self-balanced upper rotary 23
The center of gravity of platform is until balance.
When having shelter in center of gravity point of adjustment, the pillar 3 of chemical experiment iron stand platform is inserted in fixed platform 1 first
Through hole 11, fixed platform 1 is moved to the position of needs, rotational lock screw 13, tightens fixation.By two balancing poles 2
The pin hole 12 that latch 22 is inserted in fixed platform 1 is rotated, two balancing poles are located at the right and left of shelter respectively, respectively will
Two balancing poles 2 are in the horizontal plane that the center of circle is rotated to the position of needs with pin hole 12, the balancing pole of left and right two respectively with screening
The angle that block material is formed in the horizontal plane will be consistent, and tighten fixed screw 14, respectively consolidate the position of two balancing poles 2
It is fixed.The lock nut 21 of two outboard ends of balancing pole 2 is turned on respectively, on demand will by the square opening 231 at the center of balancing weight 23
One or more balancing weight 23 distinguishes two balancing poles 2 of fit on, and tightens lock nut 21 to prevent that balancing weight 23 is unexpected de-
From.By the center of gravity of the constantly regulate iron stand of balancing weight 23 on mobile two balancing poles 2 until balance.
According to circumstances, when not needing balancing pole, balancing pole 2 can be removed from fixed platform 1, it is not necessary to fixed disassembly
Platform.
When needing balancing pole, branched balancing pole and balancing weight can be applied in combination, the center of gravity of single unit system is reallocated,
Can solve the problems, such as due to instrument hinder and balancing pole can not adjust specified location, so as to reach optimum balance effect.
Simply presently preferred embodiments of the present invention described above, according to the thought of the embodiment of the present invention, in embodiment
In place of change is had in application, the content of this specification should not be construed as limiting the invention.
