Pear-shaped bottle dosing tray rack for chemical physics laboratory

Abstract

The invention provides a pear-shaped bottle liquid dispensing tray frame for a chemical physics laboratory, comprising a base plate, a marking block and a clamping nut; the base plate is a vertical plate structure with an inner groove, and two of the base plates An upper support plate and a lower support plate are respectively connected therebetween. The invention provides a pear-shaped bottle liquid dispensing tray rack for chemical physics laboratory, the adjustment box and the lower support plate are arranged, and the lower end of the spring is against the bearing fixedly arranged on the bottom plane of the adjustment tank, while the upper end of the spring is It just hits the bottom plane of the fin platform, so that the lower support plate can have a certain cushioning performance in the process of adjusting up and down, which is convenient for stability during operation, and finally realizes pear-shaped bottles that can adapt to different specifications, changing the traditional single bottle. In the fixed form, it only needs to replace the upper support plate and adjust the height of the lower support plate to adapt to pear-shaped bottles of different specifications.

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
