A gas cylinder transport trolley

Abstract

This utility model discloses a gas cylinder transport trolley, belonging to the field of trolley technology. It includes a main body, a support plate fixed to the main body, and self-locking wheels installed at the lower part of the main body. The main body is equipped with a clamping and fixing mechanism, which includes a clamping structure comprising at least two symmetrically arranged clamping pinions. This gas cylinder transport trolley utilizes a synchronous opening and closing and automatic locking mechanism formed by the clamping pinions, gear rack, pedal linkage, and top frame limit, allowing the operator to lock and release the gas cylinder without any tools by flipping the top frame and stepping on the pedal, significantly shortening loading and unloading time. The continuous restoring force provided by the hook spring and the flexible contact of the rubber pad maintain a tight clamping grip throughout the transport process, effectively suppressing slippage and coating damage caused by road bumps. When the top frame falls, its edge directly pushes the limit pin to complete the mechanical locking, forming a double constraint to prevent the clamping pins from accidentally releasing.
