Description

Technical Field

[0001] The utility model relates to the technical field of concrete testing instruments, and more specifically, to a Vicat instrument with a pre-tightening needle mechanism. Background Art

[0002] Vicat instrument, also known as cement consistency meter or cement consistency setting time tester, is an important testing instrument in the cement and concrete industry. It is mainly used to test the standard consistency water requirement and setting time of cement paste. It plays an important role in the quality control, production monitoring and research and development of cement and concrete. The preload needle mechanism of Vicat instrument is a mechanical structure designed in Vicat instrument to fix and preload the test needle. Through the preload needle mechanism, the test needle can be stably fixed on the Vicat instrument.

[0003] During the use of the traditional Vicat instrument, since the Vicat instrument has a poor mold restriction effect on the tested cement, mold slippage will cause deviations in the test data, reducing the accuracy of the test data.

[0004] After searching, a Chinese patent with application number CN202220609921.8 discloses a Vicat instrument with a pre-tightening needle mechanism. This avoids the problem that during the use of the traditional Vicat instrument body, the mold shifts during the test due to the poor restriction effect of the Vicat instrument body on the cement mold, which will cause deviation in the test data. The mold can be clamped by the clamping structure to effectively prevent the mold from sliding, thereby improving the stability of the mold and better assisting the test.

[0005] When the above-mentioned Vicat instrument with a pre-tightening needle mechanism is actually used, cement will remain on the test needle after the test, which will affect the contact between the test needle and the surface of the cement slurry during the next measurement, may cause the measured value to deviate from the true value, and will change the resistance of the test needle sinking into the cement slurry, affecting the accuracy of the measurement.
