Device for conveying high-pressure gas cylinders in tightening manner

The invention discloses a device for conveying high-pressure gas cylinders in a tightening manner. The device for conveying the high-pressure gas cylinders in the tightening manner comprises a base, wherein the base is connected with a carriage plate by vibration dampers; a fixing rack is arranged on the base; a plurality of threaded holes which are distributed equidistantly are formed in the fixing rack; threads which correspond to the threaded holes are arranged on cylinder bodies of the high-pressure gas cylinders; and the high-pressure gas cylinders are tightened in the threaded holes in a threaded manner and then are connected with the fixing rack. By the device for conveying the high-pressure gas cylinders in the tightening manner, the high-pressure gas cylinders can be fixed in a carriage, the circumstance that the high-pressure gas cylinders shake and collide with one another in a running process of an automobile is avoided, meanwhile, jolt vibration to the high-pressure gas cylinders in a running pro
