摘要

An arc-shaped lock catch (200) and an LED display screen with same. The arc-shaped lock catch (200) comprises an angle adjusting assembly (210) and a locking assembly (220). The angle adjusting assembly (210) comprises a fastening base (211), a radian plate (212), and a multi-connecting-rod mechanism (213) for enabling the radian plate (212) to move in an arc with respect to an inclined surface of the fastening base (211). The multi-connecting-rod mechanism (213) further comprises a first long connecting rod frame (2132), a second long connecting rod frame (2133), a first short connecting rod frame (2134), and a second short connecting rod frame (2135). The first long connecting rod frame (2132) and the second long connecting rod frame (2133) are rotatably arranged in a staggered manner. The first long connecting rod frame (2132) and the first short connecting rod frame (2134) are sequentially connected between a first edge of the inclined surface and a second edge of the radian plate (212), the second long connecting rod frame (2133) and the second short connecting rod frame (2135) are sequentially connected between a first edge of the radian plate (212) and a second edge of the inclined surface, and all connections are rotatable connections. The radian plate (212) is provided with a lock hole (2121) coordinating with the locking assembly (220) for locking.
