Description

Technical Field

[0001] The utility model relates to the technical field of measuring cylinders, in particular to an improved pharmaceutical experiment measuring cylinder. Background Art

[0002] A graduated cylinder is a measuring instrument used in laboratories. It is mainly made of glass, and a few (especially large ones) are made of transparent plastic. It is used to measure liquids quantitatively by volume. It is one of the measuring instruments that measures a certain volume of liquid. The graduated cylinder generally has low accuracy. It cannot be used as a reactor, absolutely cannot be heated, and cannot be used to prepare solutions or dilute solutions.

[0003] For example, the Chinese patent with application number 202020470899.4 only reinforces the measuring cylinder to prevent it from tipping over. However, during medical experiments, since the fixing frame can only fix a single measuring cylinder, it is impossible to control the changes in the experimental variables during the medical experiment, and it is also extremely inconvenient to take the measuring cylinder during use.

[0004] At present, most pharmaceutical laboratory measuring cylinders on the market are only single measuring cylinders, which is extremely inconvenient when controlling variables in experiments. Since the experimental samples are placed in the measuring cylinder, it is also very inconvenient to take them out. Utility Model Content

[0005] The purpose of the utility model is to overcome the above technical defects and provide an improved pharmaceutical experiment measuring cylinder.

[0006] In order to solve the above technical problems, the technical solution provided by the utility model is: an improved pharmaceutical experiment measuring cylinder, comprising a support rod, a measuring cylinder frame is inserted into the top of the support rod, measuring cylinder grooves are evenly arranged on the outer ring of the measuring cylinder frame, the measuring cylinder is inserted into the measuring cylinder, a hinge is arranged at one end of the measuring cylinder frame, the hinge is fixedly connected with a transparent dust cover, a rolling bearing is inserted into the bottom of the support rod, the bearing drives the measuring cylinder frame at the upper end of the support rod to rotate, and the outer ring of the rolling bearing is fixedly connected to the base.

[0007] Furthermore, an annular limit block is provided at the top of the measuring cylinder to prevent the measuring cylinder from falling off, so that the measuring cylinder will not fall out of the measuring cylinder groove.

[0008] Furthermore, the outer ring of the measuring cylinder groove is provided with a rubber ring to prevent the measuring cylinder from being damaged.

[0009] Furthermore, the measuring cylinder is provided with six grooves, which can be used to control the variables of the experiment.

[0010] Furthermore, the measuring cylinder rack is detachable and can be disassembled and replaced with measuring cylinder racks of different sizes during different experiments.

[0011] Compared with the prior art, the utility model has the following advantages: during the experiment, the measuring cylinders in the multiple measuring cylinder slots can control the variables of the experiment; since the rolling bearing is installed at the bottom, the rotation of the support rod drives the measuring cylinder rack to rotate, which improves the convenience of the experimenter in selecting different measuring cylinders as targets during the experiment, and the control of the variables by the multiple measuring cylinders is also easier; the detachable measuring cylinder rack meets the use of measuring cylinders of different sizes; the transparent dust cover protects the experimental product, and it is also easier to see the situation in the measuring cylinder.

[0017] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0018] In the description of the embodiments of the present utility model, it should be noted that if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate an orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, or the orientation or position relationship in which the utility model product is usually placed when in use, it is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0019] In addition, the terms "horizontal", "vertical", "overhanging" and the like do not mean that the components must be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.
