Title:
RECESSED LIGHT FIREPROOF STRUCTURE AND RECESSED LIGHT
Document Type and Number:
WIPO Patent Application WO/2017/140023
Kind Code:
A1
Abstract:
A recessed light fireproof structure and the recessed light thereof are provided. A fixed plate (2) of the fireproof structure is provided with a fixed column (2-1), a first limiting stud (2-2), and a fuse pin hole (2-4). One end of the fixed column (2-1) and one end of the first limiting stud (2-2) are both fixedly connected to or integrally formed with the fixed plate (2). The other end of the fixed column (2-1) and the other end of the first limiting stud (2-2) each have a threaded section. A first step surface (2-1-1) is disposed below the threaded section of the fixed column (2-1). The fixed column (2-1) has an axial cable through hole (2-1-3). A turntable (1) of the fireproof structure is provided with a fuse pin connection column (1-1), a fixed-column mounting hole (1-2), and a first limiting hole (1-3). One end of the fuse pin connection column (1-1) is fixedly connected to or integrally formed with the turntable (1). A torsion spring (3) is sleeved on the fixed column (2-1), one end of the torsion spring (3) abuts the fuse pin connection column (1-1), and the other end thereof abuts the first limiting stud (2-2). In the fireproof structure, a coil spring is replaced with a torsion spring, so that the structure is simple, and assembly is convenient. When the fireproof structure is applied to recessed lights, even if the torsion spring rusts due to the use environment, performance is not affected, thereby greatly improving reliability and safety of recessed light structures.
