This utility model discloses a railing device, relating to the field of railing technology. The device includes a post, a crossbar, and a wooden wedge-shaped locking strip. The post has a rectangular groove on its side; the crossbar has an insertion part at its end, with a wedge-shaped groove at its top; the locking strip has a right-angled trapezoidal cross-section and achieves mechanical self-locking by inserting its inclined surface downwards into the wedge-shaped groove. When the locking strip is inserted, its inclined surface presses against the inner wall of the wedge-shaped groove, forcing the insertion part to expand inwards and press against the inner wall of the rectangular groove, forming a horizontal compressive force; simultaneously, the top of the locking strip presses against the upper edge of the rectangular groove, resisting vertical pull-out force. This device uses an all-wood structure, eliminating the risk of corrosion from metal nails and extending its service life; at the same time, the wedge-shaped self-locking structure provides strong resistance to pull-out and impact, preventing loosening, and is suitable for outdoor scenarios such as parks and boardwalks.
