Description
Technical Field
The invention relates to the technical field of chemical experiments, in particular to an iron stand platform for chemical experiments.
Background
The iron stand platform is the apparatus that chemistry laboratory often used, and the iron stand platform that uses now includes the base that a monoblock iron plate was made, fixedly connected with branch on the base, is provided with the retainer plate on the branch, and the iron stand platform is used for fixing and supports various instruments, and the iron ring can replace the funnel stand to use, is generally commonly used for experimental operation such as filtration, heating, titration, is one of the most extensive instrument of use in physics, chemistry experiments, often uses with the cooperation of alcohol burner.
The existing iron stand has some disadvantages when in use: on one hand, the alcohol lamps of different models cannot be stably fixed; on the other hand can't carry out stable centre gripping to the test tube of different models, also is convenient not to adjust wantonly the height of test tube. Therefore, we propose an iron stand for chemical experiments.
Disclosure of Invention
The invention aims to solve the defects in the prior art and provides an iron stand for a chemical test.
In order to achieve the purpose, the invention adopts the following technical scheme:
the utility model provides an iron stand platform for chemistry experiment, includes the base, the welding of the top outer wall of base has the control box, and has pegged graft along vertical direction in the control box and have the lead screw, the thread bush has been cup jointed on the lead screw, and the lateral wall welding of thread bush has the connecting rod, the welding of the one end outer wall of connecting rod has the ring of placing, and places the intra-annular test tube of having placed, it is equipped with two fixture to place the intra-annular, and two fixture all include along the horizontal direction spiro union at the screw rod of placing the ring with the arc grip block of being connected through bearing and screw rod one end, the standing groove has been seted up at the top center of base, and is equipped with two fastening device in the standing groove, two fastening device all includes the spring of welding.
Preferably, two the opening part of arc grip block is central symmetry distribution, and the one side outer wall that two arc grip blocks are close to each other all contacts with the outer wall of test tube.
Preferably, an alcohol burner is placed in the placing groove, and the outer wall of one side of the two pressing plates, which are close to each other, is in contact with the outer wall of the alcohol burner.
Preferably, a slide way is arranged on one side of the operating box, and the outer wall of the connecting rod is connected with the inner wall of the slide way in a sliding manner.
Preferably, the lead screw passes through two bearings and is connected with the top inner wall and the bottom inner wall of control box respectively, and the top outer wall welding of lead screw has the carousel, and the top outer wall welding of carousel has the crank.
Preferably, the outer wall of the bottom of the base is provided with suckers distributed at equal intervals, and one side of the base is provided with a drawer.
The invention has the beneficial effects that:
1. due to the arrangement of the spring and the pressing plate, alcohol lamps of different models can be stably fixed, so that normal operation of experiments is facilitated;
2. owing to set up lead screw, thread bush and connecting rod, the lead screw rotates and drives the thread bush and remove, and final connecting rod slides in the slide, so can adjust wantonly placing the height of placing the test tube on the ring to adjust the interval between two arc grip blocks through rotating the screw rod, thereby can carry out the centre gripping to the test tube of different models.
