Title:
CHAIN RING, CHAIN TYPE LAMP, ASSEMBLY METHOD FOR CHAIN TYPE LAMP AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/040059
Kind Code:
A1
Abstract:
A chain ring, a chain type lamp, an assembly method for the chain type lamp and an application thereof. The chain ring comprises a light source (200), at least two ring formation members (300) capable of forming a ring structure, and a cover body (100). The ring structure is used as a basic connection member for a chain type lamp. In the chain type lamp, the lengths of outgoing lines of adjacent chain rings are greater than the distance between adjacent ring structures, such that the adjacent chain rings have a relative movement space. The chain type lamp can be applied to a safety guardrail, and the safety guardrail comprises vertical columns (400) and a protective chain between the vertical columns. The protective chain is a chain type lamp or at least partially chain rings. During assembly, the ring formation members are first mounted at the peripheral side of the light source, and are then assembled into the ring structure. The ring body is high in strength, and the chain rings can be fitted into each other to form a chain, so that the lamp has not only a decorative function but also a protective effect. The ring formation members are connected by means of ends, such that the ring structure has certain connection elasticity and tensile strength, and the protective effect of the lamp is improved.
