The utility model relates to a two-dimensional adjustable lifting lug self-locking type glass lifting clamp mechanism. The mechanism comprises a connector and clamping plates, wherein the connector is a U-shaped connector which is composed of a base plate and left and right two lateral plates; the base plate horizontally extends out of the lateral plates, thereby forming raised edges; vertical slot holes are formed at the middle parts of the left and right two lateral plates; the left and right two lateral plates are connected with a lifting lug steel plate which is fixed at the bottom of a cross beam at the top of a building; the base plate is connected with the clamping plates; a self-locking anti- sliding rubber mat is respectively arranged between a lower buckle edge of each of the two clamping plates and the glass; and each self-locking anti-sliding rubber mat is of a wedge-shaped structure with a wide upper part and a narrow lower part. When the two-dimensional adjustable lifting lug self-locking type glass lifting clamp mechanism provided by the utility model is used for lifting a conventional full-glass curtain wall, the quantity of required lifting clamps is greatly reduced and the mounting is more convenient. When the mechanism is applied to a large and ultra-thick full-glass curtain wall, the stressing requirement of the curtain wall is met without reducing the glass separation or increasing the quantity of the lifting clamps, and the curtain wall is efficiently prevented from sliding and the construction is safer. The two-dimensional adjustable lifting lug self-locking type glass lifting clamp mechanism provided by the utility model can be widely applied to various glass curtain walls, especially to the large and ultra-thick full-glass curtain walls.
