The invention relates to a buckle type conversion layer hanging part. The hanging part comprises upper hanging part bodies and a lower hanging part body, the upper hanging part bodies are connected with the lower hanging part body, the buckle type conversion layer hanging part comprises a damping device, each upper hanging part body comprises a first plate body and a buckling portion, the lower hanging body comprises second plate bodies, the first plate bodies and the second plate bodies are each provided with a perforating portion, each upper hanging part body is arranged on the side face of the lower hanging part body, the upper hanging part bodies are connected with the lower hanging part body through fixing components, a groove is formed in the lower hanging part body, the second plate bodies are arranged at the two sides of the groove, and the damping device is arranged in the groove and can extend and contract. By means of the hanging part, the efficiency of installing a ceiling conversion layer is improved, it does not need plenty of manpower and material resources to conduct the welding and rust-proof treatment, and the construction cost is reduced; in addition, a ceiling can be subjected to uniform stress, and ceiling cracking caused by uneven sedimentation due to the gravity is avoided.
