Description

Triangular flask anchor clamps suitable for constant temperature water-bath

Technical Field

The invention relates to the field of experimental tools, in particular to a triangular flask clamp suitable for a constant-temperature water bath kettle.

Background

The constant temperature water bath is a common instrument for biochemical experiments and is also an important instrument in assay and inspection. It can provide a stable temperature environment for experiments, and the reaction result has higher linear relation or higher correlation. When the triangular flask is heated at constant temperature, the current mainstream method is to place the triangular flask filled with the reagent in a constant-temperature water bath, and directly heat the triangular flask at constant temperature, the triangular flask can be easily overturned in boiling water, the triangular flask can not be stably placed in water, an experimenter generally needs to wear heat-insulating gloves and gas masks to hold the triangular flask, the labor intensity of the experimenter can be greatly increased, in some experiments with long time, the hand holding is not scientific, secondly, the triangular flask is directly placed at the bottom of the constant-temperature water bath, the temperature at the bottom of the triangular flask is too high, the whole triangular flask is heated unevenly and is easy to crack, and the reagent flows out, and then, a person clamps the bottleneck of the triangular flask through a traditional test tube, so that the triangular flask is suspended in the constant-temperature water bath, and is also needed to be held by hands, and the traditional test tube clamp can only clamp one triangular flask, under the condition of carrying out a plurality of sample experiments simultaneously, need use a plurality of test tube holders, too much test tube holder not only is not good to be taken and shift, and in boiling water heating process, if the test tube holder directly hangs the wall built-up of constant temperature water bath, often can lead to the triangular flask to overturn the reagent because of the unable light triangular flask of stable quality of test tube holder, and the rising of boiling water leads to the triangular flask.

Disclosure of Invention

The present invention is directed to a triangular flask clamp for a constant temperature water bath, which solves one or more of the problems of the prior art and provides at least one of the advantages.

The technical scheme adopted for solving the technical problems is as follows:

the utility model provides a triangular flask anchor clamps suitable for constant temperature water-bath, includes two splint, extend the setting around splint are, and relative parallel arrangement about two splint are, and the articulated elements that extend about the rear end of two splint is through the axis is articulated, installs the retaining member between the front end of two splint, the retaining member is used for locking the relative position between two splint, is provided with a plurality of semicircular double-layered grooves on two splint lateral walls in opposite directions all, and interval arrangement sets up around a plurality of double-layered grooves are, and the double-layered groove one-to-one on two splint corresponds, and two double-layered groove butt joints of correspondence form the axis and be the tight round hole of clamp that extends from top to bottom, are provided with fixture on one of them splint, fixture include the relative clamp splice that sets up around two being, drive clamp splice or reverse movement's centre gripping drive assembly.

The invention has the beneficial effects that: when using, the bottleneck to the triangular flask sets up between two double-layered grooves that correspond one by one, two splint rotate around the articulated elements, make two double-layered groove butt joints of corresponding press from both sides tight round hole that forms, through the relative position between two splint of retaining member locking, make the triangular flask press from both sides tightly in pressing from both sides tight round hole, rethread centre gripping drive assembly drives two clamp splice in the front and back direction in opposite directions or reverse movement, press from both sides tightly on constant temperature water bath through two clamp splices, need not the handheld anchor clamps of experimenter, make a plurality of triangular flasks can soak simultaneously and heat in constant temperature water bath, a plurality of tight round holes of clamp can correspond a plurality of triangular flasks, and can keep the relative position between a plurality of triangular flasks, avoid when boiling water bath heating, bump between the triangular flask and lead to the triangular flask to break, also avoid appearing the triangular flask come-up and appear beating the condition of turning over reagent.
