AI Technical Summary

Technical Problem

The connection of the existing folding ladder for municipal construction is unstable, which causes the device to shake easily during use, reducing safety.

Method used

Two sets of first support plates and two sets of second support plates are designed. By setting a card block, a card slot and a positioning pin structure between the first connecting plate and the second connecting plate, and using the rebound force of the adjustment component and the spring, the stable connection of the card block is achieved, and the stability between the connecting plates is improved.

Benefits of technology

Enhance the stability of the folding device in the expanded state and improve the safety of use.

Abstract

The utility model discloses a load-bearing municipal construction folding equipment, including two sets of first support plates and two sets of second support plates, the two sets of second support plates rotate on one side of the two sets of first support plates, one side of the two sets of first support plates is rotatably provided with a first connecting plate, and the first connecting plate is rotatably installed on one side of the two sets of first support plates by pulling a pull rod. The pull rod drives the base plate fixedly connected with the pull rod to move, the base plate drives the two clamping blocks to move, so that the two clamping blocks move towards the interior of the cavity, then the first connecting plate and the second connecting plate adjacent to the first connecting plate are rotated, and the pull rod is loosened after the first connecting plate and the second connecting plate are located on the same horizontal plane; two groups of clamping blocks can move under the action of resilience force of two groups of springs, the two groups of clamping blocks are respectively clamped in two groups of clamping grooves, and then positioning pins are inserted in a second connecting plate and the two groups of clamping blocks to limit the two groups of clamping blocks, so that the stability between the first connecting plate and the second connecting plate is improved; and the stability of the device is improved.
