Description

Technical Field

[0001] The utility model relates to a fixing device, in particular to a fixing pull rod assembly device for an exhaust pipe of a gas cylinder safety valve. Background Art

[0002] Currently, heavy-duty truck natural gas cylinders are typically top-mounted, secured to the vehicle frame behind the cab. The cylinder safety valve exhaust pipe is located at the rear of the cylinder, tapering downward at a 45-degree angle to the ground. For side-mounted cylinders, the cylinders on either side of the longitudinal beam are connected in series, requiring the exhaust pipes of the safety valves to be connected in series. Export regulations require these exhaust pipes to be routed to the rear of the vehicle and to the bulge in the cab. These long exhaust pipes are prone to shaking and breaking when the vehicle is operating in harsh conditions if not securely secured. Utility Model Content

[0003] The purpose of the utility model is to provide a heavy truck gas cylinder safety valve exhaust pipe fixing pull rod combination device, which adopts a pull rod structure and a support rod for fixed connection, and reliably fixes the safety valve exhaust pipe, thereby preventing the safety valve exhaust pipe from shaking and breaking during the vehicle's driving under harsh working conditions, and solves the current problem of heavy truck gas cylinder safety valve exhaust pipes being unfixed.

[0004] The utility model is realized by the following technical solutions:
