Description of the embodiments

In the description of the present utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings are merely for convenience in describing the present utility model and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present utility model.

Referring to fig. 1 to 3, a ceiling plug expansion joint comprises a counter-pulling joint 1 and an expansion iron sleeve 2, wherein the counter-pulling joint 1 comprises a connecting section 3 and a counter-pulling section 4, the bottom of the connecting section 3 is connected with the top of the counter-pulling section 4, the diameter of the connecting section 3 is larger than that of the counter-pulling section 4, the lower part 41 of the counter-pulling section 4 is cylindrical, the diameter of the upper part 42 of the counter-pulling section 4 is gradually increased from bottom to top, and the connecting section 3 and the counter-pulling section 4 are integrally formed. The expansion iron sleeve 2 is sleeved on the periphery of the reverse pulling section 4, the height of the expansion iron sleeve 2 is lower than that of the reverse pulling section 4, three upper notches 5 are formed in the periphery of the upper portion of the expansion iron sleeve 2, the upper portion of the expansion iron sleeve 2 is divided into three expansion pieces 6 by the three upper notches 5, reverse pulling convex portions 7 are arranged on the outer side face of each expansion piece 6, and screw holes 31 are formed in the bottom of the connecting section 3. The counter-pulling convex portion 7 of each expansion sheet 6 includes a small counter-pulling convex portion 71 and a large counter-pulling convex portion 72, and the large counter-pulling convex portion 72 is located below the small counter-pulling convex portion 71.
