AI Technical Summary
Existing low-voltage withdrawable distribution cabinets use a sliding structure, which makes it difficult to pull out heavy objects when they are placed on the support plate. The structure is also unstable and prone to sliding out.
The guide rail employs anti-slip components, including a pressing plate, a straight spring, a rotating shaft, a spur gear, and an air chamber piston plate system. Through the friction between the pressing plate and the bearing plate and the limiting effect of the air chamber piston plate, combined with the design of rollers and slide plates, the bearing plate is stably clamped and limited.
It improves the ease of pulling out the load-bearing plate and its stability, avoids slippage, and enhances the safety and efficiency of the sliding structure.
