The invention discloses an iron stand for chemical test. The iron stand comprises a base, an operation box is welded to the outer wall of the top of the base, a lead screw is inserted into the operation box in the vertical direction, the lead screw is sleeved with a threaded sleeve, a connecting rod is welded to the side wall of the threaded sleeve, a containing ring is welded to the outer wall ofone end of the connecting rod, and a test tube is placed in the containing ring; and two clamping mechanisms are arranged in the placing ring, each clamping mechanism comprises a screw rod connectedto the placing ring in a threaded mode in the horizontal direction and an arc-shaped clamping block connected with one end of the screw rod through a bearing, and a placing groove is formed in the center of the top of the base. Due to the arrangement of the screw rod, the threaded sleeve and the connecting rod, the screw rod rotates to drive the threaded sleeve to move, and finally the connectingrod slides in the slide way, so that the height of a test tube placed on the placement ring can be adjusted at will, and the distance between the two arc-shaped clamping blocks is adjusted by rotatingthe screw rod; therefore, test tubes of different models can be clamped.
Description
technical field [0001] The invention relates to the technical field of chemical experiments, in particular to an iron stand for chemical experiments. Background technique [0002] The iron stand is an instrument often used in chemical laboratories. The iron stand used now includes a base made of a whole piece of iron plate. A support rod is fixedly connected to the base. And support various instruments, the iron ring can be used instead of the funnel rack, generally used in experimental operations such as filtration, heating, titration, etc. It is one of the most widely used instruments in physical and chemical experiments, and is often used in conjunction with alcohol lamps. [0003] The existing iron stand has some disadvantages in use: on the one hand, it is impossible to stably fix different types of alcohol lamps; on the other hand, it is impossible to stably clamp different types of test tubes, and it is also inconvenient to adjust the height of the test tubes arbitrar...
