A flip ladder

Abstract

This utility model discloses a tilting ladder, including a base plate. The base plate has a fixing mechanism, which includes: fixing plates fixedly installed on both sides of the top of the base plate; rotating holes opened on the sides of the two fixing plates that are close to each other; a first rotating rod and a second rotating rod rotatably installed in the two rotating holes respectively; and both ends of the first and second rotating rods extending outside the rotating holes. This utility model adopts a fixed rod-hole mechanical locking structure, completely solving the problem of accidental unfolding caused by friction wear in traditional tilting ladders, significantly improving driving safety. The sliding block linkage mechanism allows for single-handed operation to fix / release the ladder frame. The rotating arm-top rod structure ensures that the ladder frame automatically positions itself to the optimal usage angle after unfolding. The modular design (fixed plates / rotating rods / sliding grooves, etc.) reduces maintenance costs, and the aluminum alloy material reduces weight while maintaining structural strength.

Description

Technical Field

[0001] This utility model relates to the field of flip ladder technology, specifically a flip ladder. Background Technology

[0002] To address the issue of the inability to install pull-out ladders in carriages or platforms, and to ensure convenient, quick, and safe access for operators to enter and exit carriages or platforms, a new type of tilting ladder has been developed. This tilting ladder can be vertically fixed after being folded up, occupies less space inside the carriage or platform, and can be applied in various fields.

[0003] Existing vehicle-mounted tilt ladders rely on the friction between the ladder frame and the fixed plate for opening and closing. However, with prolonged use, the friction between the ladder frame and the fixed plate will decrease, which may cause the tilt ladder to open automatically while the vehicle is in motion, potentially posing a danger.
