Description

Technical Field

[0001] The utility model relates to the technical field of fluidity measuring instruments, and specifically, to a cement mortar fluidity measuring instrument. Background Technique

[0002] A fluidity measuring instrument is a device used to measure the fluidity performance of substances. It is widely used in multiple fields such as chemical engineering, building materials, and transportation. Generally, a special funnel or a vibrating table structure is used to measure the spreading diameter or flow time of substances under constant temperature and fixed time conditions, so as to evaluate their fluidity performance;

[0003] For example, the Chinese utility model patent disclosed with the publication number CN218726369U: A cement mortar fluidity measuring instrument. In this application, a vibrating table is provided above the vertical shaft, the lower surface of the vibrating table is connected to the upper surface of the vertical shaft, and a truncated conical mold is provided above the vibrating table. When measuring the fluidity performance of cement mortar, the cement mortar needs to be poured into the truncated conical mold in two times, and after each pouring of the cement mortar, it is necessary to vibrate the cement mortar placed in the truncated conical mold with a vibrating rod. Since the truncated conical mold is directly placed on the vibrating table, when vibrating the cement mortar in the truncated conical mold, only one hand can press the truncated conical mold. However, in the actual operation process, because the operator's two hands need to hold the truncated conical mold and vibrate the cement mortar in the truncated conical mold respectively, and the surface of the vibrating table is relatively smooth, it is easy to cause the truncated conical mold to drive the cement mortar to displace when vibrating the cement mortar in the truncated conical mold, thus affecting the position of the cement mortar after flowing and spreading, making the scale on the transparent plate in this application unable to accurately measure the fluidity performance data of the cement mortar. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a cement mortar fluidity measuring instrument, which can effectively solve the problem in the background technique that when vibrating the cement mortar through the ring cup sleeve, it is easy to cause the ring cup sleeve to displace and affect the fluidity measurement data of the cement mortar.
