Water-bath fixing frame with adjustable size

Abstract

The invention provides a water-bath fixing frame with an adjustable size. The water-bath fixing frame comprises a plurality of circular rings with adjustable radii and a plurality of vertical rods; the vertical rods are arranged on the circumference of the circular rings to form a cylindrical cup rack, and the tail ends of the vertical rods bend towards the outer side of the cylindrical cup rack to form supporting feet; two ends of each circular ring are respectively provided with a sawtooth part, the tail end of each sawtooth part is provided with a spring cord fastener, and the sawtooth parts at the two ends of circular ring are movably connected through the spring cord fasteners; a plurality of telescopic rods are arranged at the bottom of the cup rack, each telescopic rod is composed of two cross bars, one end of each cross bar is connected with the circular ring located at the bottom of the cup rack, the other end of each cross bar is provided with a buckle, and the two cross bars mutually pass through the buckles and are movably connected through the buckles; and counterweight blocks are arranged below the supporting feet. The water-bath fixing frame is used for water-bath heating of a drug or reagent, can fix a beaker or test tube, prevents shaking or inclination caused by boiling of water, allows the beaker or test tube to be suspended, avoids uneven heating, can adjust the size of the cup rack and is applicable to single water-bath heating of beakers or test tubes of different sizes.

Description

technical field [0001] The invention relates to a fixing device for water bath heating, in particular to a size-adjustable water bath fixing device. Background technique [0002] In geological experiments, it is often necessary to heat medicines or reagents in a water bath. In the traditional water bath method, when the water boils, it is easy to shake and tilt the beaker or test tube, and even the boiling water splashes into the medicine or reagent, resulting in contamination of the medicine or reagent. If you always hold the beaker or test tube in the water bath by hand, it is time-consuming, laborious and easy to burn. However, the existing water bath fixing frame can only place beakers or test tubes of fixed size usually, and when changing the water bath device of different size, it is necessary to be equipped with a corresponding fixing frame in addition. Some water bath fixtures are only suitable for batch water bath heating, not suitable for single water bath heatin...
