The invention discloses gas cylinder inflation equipment for hydrogen production in the technical field of inflation equipment, which comprises a base, a vertical plate is arranged on one side of the base, a fixed arm is arranged on the vertical plate, a mounting plate is vertically and rotatably connected to the fixed arm through a rotating shaft, a valve body opening and closing mechanism is connected to the mounting plate, a support arm is arranged on one transverse side of the vertical plate, and a valve body opening and closing mechanism is connected to the valve body opening and closing mechanism. A translation air cylinder is horizontally installed on the supporting arm, an inflation head is connected to the translation air cylinder in a driving mode, the inflation head is communicated with external gas conveying equipment through a pipeline, a plug is coaxially connected to the inflation head in a penetrating mode, a pressing mechanism is arranged on the plug, and the inflation head drives the valve body opening and closing mechanism to rotate through a driving mechanism. Due to the fact that the switching valve does not need to be operated manually, the inflation head does not need to be inserted into the quick insertion connector manually, automatic inflation is achieved, in addition, due to the fact that the inflation head moves, the valve body opening and closing mechanism can tighten or open the switching valve, and the automation degree is high.
