Abstract

The invention discloses an anti-motion fluid timing device and a universal suspension structure thereof. The inner ring is fixed with the inner kettle body, is provided with a horizontal transverse shaft in rotary fit with the outer ring, and the two shafts are mutually perpendicular in horizontal direction. The stroke of the inner kettle body is 77mm (which is counted by one third of Chinese ruler), the inner diameter is 42mm, and the aperture of the flow port is 0.90mm. The inner pot has dual mode timing functions of 180 seconds (push-in type) and 450 seconds (drain type). The weight center of the inner kettle is regulated by a counterweight or a mounting height, so that the weight center is always lower than the transverse axis, and the inner kettle is automatically aligned and kept plumb when being inclined. The device was suspended from the horses bridle and the vertical disturbances were eliminated by damping Ma Gengbu. Theoretical calculation verifies that the double-mode timing error is less than 9 seconds, and can be used for teaching demonstration, museum restoration, military timing and literature products.

Description

Anti-motion fluid timing device and universal suspension structure thereof Technical Field The invention relates to the technical field of timing instruments, in particular to a fluid timing device capable of keeping timing precision in a motion environment and a universal suspension structure for realizing the function, which are particularly suitable for the motion timing requirement of ancient double-mode etching (such as Han-Ying-wrong-car-horse-copper-leakage). Background Ancient gimbal structures (e.g., the Tang Dynasty silver sachet) achieve horizontal retention of spherical containers in motion, but their structural design is highly dependent on the symmetry of the spherical container. The copper kettle of Han dynasty is carved with the leak and is cylindrical, its inner space distribution has essential difference with spherical container, can't apply the existing gimbal structure directly. How to realize universal balance in the cylindrical kettle body and ensure the accuracy of water discharge timing at the same time becomes a technical problem to be solved urgently. Of particular note, the Chinese silver staggered horse copper drain (Chinese staggered silver) is a unique dual mode timer which can achieve 0.2 (180 seconds) timing by push-in (static) and 0.5 (450 seconds) timing by drain (dynamic). The dual-mode design has extremely high requirements on levelness of the kettle body, and the accuracy can not be ensured during dynamic use (draining). Therefore, a structure that can maintain both the level in motion and the timing accuracy is required. The sports biomechanics research shows that the stability of the head of a horse is obviously better than that of the trunk when the horse runs, namely, the neck effectively isolates the trunk oscillation caused by the movement of the forelimbs through a muscle and ligament system, so that the head can be kept relatively stable. The measured data indicate that the vertical acceleration of the head is only about 1/5 of the torso during fast and running gait, a characteristic that provides a natural basis for stable operation of the device （Dunbar DC, Macpherson JM, Simmons RW, Zarcades A.
