Description

Technical Field

[0001] The present invention relates to the technical field of anti-vibration rods, and specifically to reinforced anti-vibration rods.

Background Art

[0002] In this era when earthquakes occur frequently, it is very important to effectively protect indoor furniture from vibration. Especially for large furniture, if it topples during an earthquake, it can not only cause property losses but also pose a significant threat to people's safety.

[0003] Currently, there are some anti-vibration rods installed between furniture and the ceiling board in the market, aiming to prevent furniture from toppling during earthquakes. However, conventional anti-vibration rods have many drawbacks. On the one hand, their load-bearing capacity is low, they are difficult to withstand large pressures, and when the seismic intensity is high, they may not be able to effectively support the furniture, and the risk of the furniture toppling still exists. On the other hand, both ends of conventional anti-vibration rods have a small contact area as the supporting surface, resulting in low support stability. When the contact area is small, the local pressure becomes too large, which affects the fixing effect of the anti-vibration rod and at the same time makes it difficult to maintain a stable supporting state during the shaking of an earthquake.

[0004] To sum up, since conventional anti-vibration rods have obvious defects in terms of load-bearing capacity and support stability, there is an urgent need for a reinforced anti-vibration rod.
