Universal adjusting fixing device for chemical experiments

Abstract

The invention discloses a universal adjusting fixing device for chemical experiments. The universal adjusting fixing device comprises an operation table and support plates; first fixing plates are fixedly connected to two sides of the top surface of the operation table, a group of first lead screws are rotationally connected between the first fixing plates; a driving motor is fixedly connected tothe outer sides of the supporting plates, and the output shaft of the driving motor is connected to one of the first screw rods through a first transmission mechanism; a first sliding seat is furtherconnected to the two first lead screws in a threaded mode, two ends of the top surface of the first sliding seat are fixedly connected to second fixing plates respectively, a second lead screw is rotationally connected between the second fixing plates, and a second sliding seat is connected to the second lead screw in a threaded mode; the end part of one end of the first sliding seat is further fixedly connected to a speed reducing motor, and an output shaft of the speed reducing motor is fixedly connected to the end part of the second screw; and the top surface of the second sliding seat is fixedly provided with a pneumatic telescopic mechanism, the output shaft of the pneumatic telescopic mechanism is connected to a connecting plate, and one side of the connecting plate is fixedly connected to a universal clamp. According to the universal adjusting fixing device, the problems that an existing fixing mechanism is complex in operation and inaccurate in position are solved.

Description

technical field [0001] The invention relates to the technical field of chemical instruments, in particular to a universal adjustment and fixing device for chemical experiments. Background technique [0002] The instruments used in chemical experiments are called chemical instruments. Materials can be metered or reacted. It is mainly divided into measuring instruments and reaction instruments. Combine the instruments in a specific way to form a device to achieve the purpose of the experiment. [0003] Since most of the chemical equipment are general-purpose equipment, they can only be used in a specific experimental process, and cannot achieve the general purpose. However, most of the existing position fixing mechanisms are mechanical structures, the fixing operation is cumbersome, and the fixing position is not accurate.
