[0002] In today's era with frequent earthquakes, it is crucial to provide effective shockproof protection for indoor furniture. Especially for large furniture, if it topples during an earthquake, it will not only cause property losses but also pose a serious threat to the safety of personnel.
[0003] Currently, there are some shockproof rods installed between furniture and the ceiling on the market, aiming to prevent furniture from toppling during an earthquake. However, the existing shockproof rods have many deficiencies. On the one hand, their load-bearing capacity is low and it is difficult to withstand large pressures. When the earthquake intensity is relatively large, they may not be able to effectively support the furniture, resulting in a risk of the furniture still toppling. On the other hand, the two ends of the existing shockproof rods serve as the supporting surfaces, and their contact areas are small, resulting in low supporting stability. The small contact area is likely to cause excessive local pressure, affecting the fixing effect of the shockproof rod, and it is also difficult to maintain a stable supporting state during the earthquake shaking.
