Abstract

The invention relates to a quick self-locking hook. The quick self-locking hook comprises an assembling part and a hook body which are connected with each other. The hook body comprises a rod body contact part at the upper section and an extension part at the lower section; and the assembling part is arranged below the extension part. The inner side of the rod body contact part is provided with an arc-shaped first curved surface. The extension part extends downwards in inclined mode so that gravity center of the hook body is located below a first curved surface, and the hook body is in a shape like a question mark . The free end of the rod body contact part is provided with an open groove. A rotating shaft penetrates through the middle of the self-locking piece to be pivoted to the open groove, and the self-locking piece can rotate around the rotating shaft. One end of the self-locking piece is an adjusting part embedded into one side of the open groove, and the other end of the self-locking piece is an abutting part used for fastening the rod body. The inner side of the self-locking piece is provided with an arc-shaped second curved surface which is concentric with the first curved surface and has the same diameter with the first curved surface. A central angle B corresponding to an arc projection formed after the first curved surface and the second curved surface are aligned is larger than 180 degrees. The hook can rapidly achieve automatic locking, is simple in structure, does not need to waste time and labor, and is high in working efficiency.

Description

technical field [0001] The present application relates to the technical field of stage lighting accessories, in particular to a quick self-locking hook. Background technique [0002] TV studios, theaters, performing arts halls, bars, mobile performance venues and other places need to use stage lamps to render the lighting environment. Since the stage lamps need to be adjusted frequently according to the content of the performance, the stage lamps are generally installed and fixed in a detachable way, and the lamps are hung on the suspenders or trusses through the hooks. [0003] Nowadays, the installation of stage lamps is generally to connect the hook body with the lamps through the connecting device and then hang them on the boom or truss. There are generally two installation methods of lamps: hanging installation and side hanging installation. For the two installation methods, the lamps are installed through the installation hooks, and the installation hooks are all clam...
