Measuring cylinder vertically-arranged and collision avoidance structure

Abstract

The invention discloses a measuring cylinder vertically-arranged and collision avoidance structure which comprises a neck sleeve sleeved at an upper end of a measuring cylinder and a base where a bottom end is rotatably inserted. The neck sleeve is an elastomer construction member with an annular opening, and an inner hole of the neck sleeve is tied on an outer wall of the measuring cylinder. The base is a flange-shaped construction member with 4-8 edges, a bottom hole with an upward middle part is a screw hole, and an inner diameter of the screw hole is equal to an outer diameter of the measuring cylinder. A notch is arranged on an outer round edge of an upward bottom hole on the base opposite to degree scales at a bottom end of the measuring cylinder. Radius of the neck sleeve is smaller than a vertical distance between an outer edge of the base and a centre, the horizontally-arranged measuring cylinder is low in opening part and high in bottom part, and washing liquid can be conveniently discharged along a slope. The abducent neck sleeve and the base form a radial protection structure of the outer wall of the measuring cylinder, positions between outer walls of the measuring cylinders are separated by the neck sleeve and the base during washing in batch, collisions can be avoided, possibilities of damage are greatly reduced, and the measuring cylinder vertically-arranged and collision avoidance structure is suitable for measuring cylinder configuration with various specifications.

Description

technical field

[0001] The invention relates to a protective structure for glassware, in particular to an anti-collision structure for measuring cylinders standing upright. Background technique

[0002] Measuring cylinder is a traditional volumetric measuring equipment, which is widely used in medical, chemical, pharmaceutical and other industries for measurement and testing in laboratories and laboratories. Measuring cylinders are usually made of glass. In addition to being transparent and easy to observe, glass measuring cylinders have stable chemical properties, high mechanical strength, and strong corrosion resistance. The structural form of most glass measuring cylinders is a thin-walled slender equal-diameter tube, which is simple in structure, easy to manufacture, and accurate in measurement. Glass measuring cylinders are fragile and should be handled with care when using them. The exposed measuring cylinders should not be cleaned in batches after use, as they may co...
