Pear-shaped bottle liquid-preparation tray rack for chemical-physical laboratory

Abstract

The invention provides a pear-shaped bottle liquid-preparation tray rack for a chemical-physical laboratory. The pear-shaped bottle liquid-preparation tray rack comprises base plates, marking blocks and clamping nuts, wherein the base plates are vertical-plate structures with inner grooves, and an upper supporting plate and a lower supporting plate are respectively connected between the two base plates. The pear-shaped bottle liquid-preparation tray rack provided by the invention has the beneficial effects that an adjusting box and the lower supporting plate are arranged, the lower ends of springs abut against a bearing fixedly arranged on the plane of the bottom part of the adjusting groove and the upper ends of the springs just abut against the plane of the bottom part of a wing platform, so that the lower supporting plate can have certain cushioning performance in the process of up-down adjustment, convenience is provided for stability in the operation process, the adaptability to different specifications of pear-shaped bottles can be finally realized, the traditional single-fixing form is changed, and different specifications of pear-shaped bottles can be adapted only by replacing the upper supporting plate and adjusting the height of the lower supporting plate.

Description

technical field [0001] The invention relates to the technical field of laboratory appliances, more specifically, to a pear-shaped bottle liquid dispensing tray rack used in a chemical physics laboratory. Background technique [0002] At present, there are many kinds of racks used in laboratories such as school teaching and scientific research institutes, among which the style and type of pear-shaped bottle racks used to place pear-shaped bottles are rare; pear-shaped bottles are inverted conical The glass container used in the laboratory cannot be placed independently on the workbench, and a special shelf is required, such as a general-purpose chicken heart bottle shelf in the patent application CN201620476806.2, which belongs to the technical field of laboratory appliances; The invention can be used to place chicken heart bottles of different sizes, and has versatility; and in the experimental operation, it is convenient to observe the phenomenon and easy to use. The prese...

Problems solved by technology

[0006] In summary, the present invention provides a pear-shaped bottle liquid dispensing tray rack for chemical physics laboratories, through the improvement of structure and functionality, to solve the problem that the pear-shaped bottle is not easy to place due to the irregular structure of the pear-shaped bottle, and In the placement process, it is often necessary to configure the corresponding bench according to different specifications, which is costly and takes up a lot of space. However, the rack body in the above-mentioned patent solves the problem of different specifications by clamping. But it is not easy to mark, and it is easy to confuse the experimental process
