The longitudinal buffer assembly 3 comprises a buffer column 31 for installation, a connecting piece 34 for installation is arranged on one end of the buffer column 31, an installation table 32 for reinforcement is arranged on the other end of the buffer column 31, a buffer spring 33 for buffering the door frame 1 is arranged on the installation table 32, and a roller 35 for sliding is further arranged on the installation table 32. A placing groove 12 for cooperation with the longitudinal buffer assembly 3 is further arranged on the door frame 1, and a transverse buffer assembly 2 for further buffering the roller 35 is further arranged in the placing groove 12.

[0023] In actual use, when the staff needs to close the door, the door body 11 can be pushed to displace the door frame 1, and in the displacement process of the door body 11, the longitudinal buffer assembly 3 can be driven to displace, and in the process of the longitudinal buffer assembly 3 gradually approaching the door frame 1, the roller 35 will first contact the placing groove 12, and then in the process of the door body 11 continuously approaching, the included angle between the buffer column 31 and the door body 11 will change, so that the mounting table 32 can compress the buffer spring 33, and under the action of the buffer spring 33, the impact force generated during the closing of the door body 11 can be effectively unloaded, thereby effectively reducing the impact force of the door body 11, and in the process of the continuous displacement of the door body 11, the roller 35 can be driven to displace towards the transverse buffer assembly 2, and when contacting the transverse buffer assembly 2, the transverse buffer assembly 2 can further unload the roller 35, until the buffer column 31 is folded and can be completely received in the door body 11, and at this time the door body 11 is closed.

[0024] The technical effects brought by the above embodiment are: by arranging the transverse buffer assembly 2 and the longitudinal buffer assembly 3, the impact force generated when the door body 11 is closed can be effectively resolved, avoiding the direct transmission of the large impact force generated during closing to the wall, which can cause cracks, looseness and other problems in the wall, thereby affecting the stability and safety of the entire civil engineering project.
