[Red sandalwood pavilion style Big Bell]
Red sandalwood pavilion style Big Bell, Qing Palace Office, Qing Qianlong, height 330 cm, base 145 × 96 cm
On the front of the pavilion on the first floor of the clock is a two-needle clock dial, with five upper chord holes arranged from left to right for clock keeping, clock keeping, clock leaving, clock carving, and clock making. They use the lead weight hanging from the string of the sheep’s intestines as the power source. After the string is wound, the lead weight falls down to generate power, driving the gear transmission system. The three bronze bells that were buckled on the second and third floor pavilions are used for striking the clock, timing, and engraving from top to bottom. There is a hammer next to the clock, which is connected to the core transmission system.
