A protective cap for a viscosity machine

Abstract

The invention discloses a protective cap of a viscosity meter. The protective cap is formed by mixed connection of a cap base, a connecting base and a boss, wherein the cap base is cylindrical; a circumferential edge of a lower round surface of the cap base is turned into a circle of outer round angle; the connecting base is cylindrical and located above the cap base; a lower round surface of the connecting base is connected with an upper round surface of the cap base in a mixed manner; the boss is cylindrical and located above the connecting base; a lower round surface of the boss is connected with an upper round surface of the connecting base in a mixed manner; a lower round hole is dug upwards in the lower round surface of the cap base; a circumferential edge of a lower hole surface of the lower round hole is turned into a circle of inner round angle; a connecting hole is dug upwards in an upper hole surface of the lower round hole and communicated with the lower round hole; a middle round hole is dug upwards in an upper hole surface of the connecting hole and communicated with the connecting hole; and an upper round hole is dug downwards in the middle of an upper round surface of the boss and communicated with the middle round hole.

Description

technical field [0001] The invention relates to a protective cap of a viscosity machine, in particular to an important part of a new instrument for measuring the viscous resistance of a liquid and the absolute viscosity of a liquid—the viscosity machine. Background technique [0002] Viscometer is widely used to measure the viscosity of oil, paint, food, medicine, adhesive and other fluids. Usually, it is required to measure the viscosity of various fluids in order to understand, grasp and improve the quality of the product, and to achieve this purpose, it is most necessary to complete the measurement with a viscosity machine with good performance. The existing viscosity machines are imported and expensive; some of the domestic ones have large errors, are inconvenient to use, and fail to achieve the purpose; our company has innovated and manufactured a new, practical and low-cost new type of viscometer in years of research and experiments. The viscosity machine has good qua...

Problems solved by technology

[0003] In order to overcome the defects of the protective cap of the ordinary viscosity machine, such as unstable operation, inaccurate measurement, large error, and influence on product quality caused by wrong design and unreasonable structure, the present invention provides a protective cap for the viscosity machine. The protective cap is an important part of the viscosity machine. The design is correct and the structure is reasonable, which can make the viscosity machine work stably, ensure accurate measurement, stable performance, high precision, and detection in place.
