[0002] Dangerous goods refer to items that are prone to combustion, explosion, corrosion, poisoning or radioactivity, and are likely to cause personal injury and property loss during transportation and storage. Special protective facilities and measures must be taken for these goods. Transport vehicles are vehicles used to transport these dangerous goods. Moreover, most of these dangerous goods transport vehicles are relatively large in size, and are likely to be dangerous in the event of a collision. Therefore, special protective devices are required to protect the dangerous goods transport vehicles.

[0003] For example, Chinese patent application number CN201821470429.7 is a rear protective device for a dangerous goods transport vehicle, which relates to the technical field of dangerous goods transport vehicles and aims to solve the problem that when a foreign object hits the guardrail, the guardrail is deformed and the deformation cannot be restored, which still causes damage to the dangerous goods transport vehicle. The key points of its technical solution are that it includes a rear crossbeam and a bumper, a rear column is connected between the rear crossbeam and the bumper, and a buffer device is connected to the rear crossbeam. The buffer device includes an elastic member and a rectangular protective plate; the front of the rear crossbeam and the front of the bumper are connected to support rods, and the four corners of the protective plate are respectively connected to the support rods; an elastic member is arranged between the protective plate and the bumper. By setting a buffer device, the utility model is compressed when hit, and part of the kinetic energy of the vehicle is converted into the elastic potential energy of the elastic member, reducing the energy of the vehicle hitting the rear of the dangerous goods transport vehicle, thereby achieving the purpose of improving the protective performance.

[0004] However, in actual use, the above device provides protective support for the dangerous goods inside the transport vehicle through the protective plate, and the length of the rear column is fixed, which is inconvenient to be applied to the rear interior of transport vehicles of different sizes and has limitations.
