This invention relates to the field of air conditioning and refrigeration engineering technology, specifically to a plug structure, an air conditioner housing, and an air conditioner. The problem this invention solves is that the plug structure cannot completely secure a wire mesh cover. An embodiment of this invention provides a plug structure connected to a plug groove located in an air conditioner. The plug structure comprises: a plug body that engages with the plug groove, at least a portion of which enters the plug groove; a first connecting portion connected to the plug body, at least a portion of which contacts the wire mesh cover, and the first connecting portion is located on the side of the wire mesh cover closer to the air conditioner; and a stop portion connected to the first connecting portion, which contacts the air conditioner. The first connecting portion is rotatable relative to the plug groove, and the stop portion contacts the air conditioner during rotation.

This utility model discloses a sleeve device for controlling the position of crushed stone piles during construction, relating to the field of building construction technology. It includes a cylinder with a support ring on its upper surface, which is welded and fixed to the cylinder. A base plate is located below the outer wall of the cylinder and is fixedly connected to the cylinder. Multiple circular holes are opened inside the base plate. A circular ring is located below the inner wall of the cylinder, and a flared cylinder is provided on its upper surface, fixedly connected to the circular ring. By installing the base plate on the outside of the cylinder, with circular holes in the base plate, collision bolts can be installed in the holes, allowing for precise fixing of the sleeve position and ensuring accurate placement of the crushed stone pile. Installing connecting parts, wheels, rubber rings, flared cylinders, and shafts inside the cylinder provides a stable channel for crushed stone pile construction, reduces cylinder friction during construction, and ensures the verticality of the crushed stone pile.
