Abstract:
A fastening structure (100), comprising a fastening member (1) and a fastening body (2); the fastening body (1) comprises a first fastening portion (12) extending axially, and the fastening body (2) is provided with a connection hole (3) fitting the fastening member (1), the connection hole (3) being provided with locking portions (31) and avoidance portions (32), wherein the perpendicular distance between each locking portion (31) and the axis of the connection hole (3) is less than the radius of the first fastening portion (12), and the perpendicular distance between each avoidance portion (32) and the axis of the connection hole (3) is greater than the radius of the first fastening portion (12). A lamp (200), comprising a surface cover (4), a housing (5), a lighting module (6) and a fastening structure (100); the lighting module (6) is fastened and connected to the housing (5) by means of the fastening structure (100), and the surface cover (4) is located at the side of the lighting module (6) away from the housing (5) and is fixedly connected to the housing (5). By means of such an arrangement, by providing the connection hole having no thread on the fastening body, the machining cost is reduced, and the production efficiency is increased. By providing the locking portions and the avoidance portions on the connection hole, the torque is reduced, and the locking and fixing for a die-casting member are easily and conveniently achieved. Providing the big-end-up connection hole on the fastening body facilitates pressing-in and locking of the locking member.
