This utility model discloses a scratch-resistant dining table, including a tabletop, a height adjustment mechanism, a mounting and locking mechanism, and a locking auxiliary mechanism. The height adjustment mechanism includes an anti-scratch plate, a bottom support plate, a top support plate, a hinge frame, and a hydraulic cylinder. The mounting and locking mechanism includes a locking tube, a locking rod, an annular groove, an embedded plate, a turntable, and a driving plate. The height adjustment mechanism improves the wear resistance and service life of the tabletop by setting an anti-scratch plate on the top of the tabletop. The use of paired hinge frames and hydraulic cylinders ensures smooth and stable lifting. The locking rod and locking tube can be quickly inserted. The embedded plate and the annular groove complete stable locking, improving assembly efficiency. The spring support pin provides continuous pushing force to the rotating ring, making the rotation of the plate more stable and reliable. The clamping ring clamps the driving plate through a threaded adjustment method to prevent rotational loosening and improve the overall locking force of the connection.
