An adjustable angle anti-fall sign

By using structural components such as hinge blocks, connecting rods, and clamping frames, as well as designs such as worm gears, worm wheel teeth, and rotating tables, stable clamping, multi-angle adjustment, and smooth movement of the signs are achieved. This solves the problems of low installation efficiency, inconvenient observation, and easy tipping of signs, ensuring the continuity of safety warnings.

AI Technical Summary

Technical Problem

The existing signs are inefficient to install, replace, and dismantle; their fixed angles make them difficult to observe; they are easily lost or tipped over; and they are difficult to see clearly in complex environments, affecting the continuity of safety warnings.

Method used

The mechanical clamping of the signboard is achieved by using structural components such as hinge blocks, connecting rods, and clamping frames. Multi-angle adjustment is achieved by combining structures such as worm gears, worm wheel teeth, and rotating tables, and stable movement of the equipment is ensured by brake wheels.

Benefits of technology

It improves the connection strength and installation efficiency of signs, allows for flexible adjustment of display posture, reduces labor time, avoids tipping and loss, and ensures the continuity of safety warnings.

Abstract

This utility model relates to the field of public facilities technology and is an adjustable-angle anti-fall sign. It solves the technical problems of signs being easily lost or tipped over, inconvenient observation due to non-adjustable angles, and low efficiency in disassembly and displacement. The sign includes a placement box at the rear. Side rectangular grooves are provided on both sides of the front of the placement box, with limit blocks slidably installed in each groove. Side grippers are fixedly installed at the ends of the limit blocks. An upper rectangular groove is provided on the front surface of the placement box, with a limit plate slidably installed in it. An upper gripper extending to the front of the placement box is fixedly installed at the end of the limit plate. By incorporating structural components such as hinge blocks, connecting rods, and clamping frames, this utility model allows for simultaneous movement of the upper push rod and clamping frame by simply moving a lever, enabling the side grippers and upper grippers to clamp or open the sign synchronously. This effectively solves the technical problem of signs being difficult to disassemble and replace.
