Problems solved by technology

When the chain with this structure is hoisted, the notch is a weak link. When the chain is subjected to gravity or instantaneous impact, the notch of the buckle will open. Even if it is welded together, the notch will still break.

Embodiment Construction

[0019] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0020] Please refer to figure 1 , is a three-dimensional schematic diagram of the first embodiment of the chain provided by the present invention. The chain 1 includes a plurality of chain pieces 11 connected in series, each of the chain pieces 11 is formed by folding metal sheets 111 with through holes 1111 at both ends, and each adjacent chain piece 11 is the next chain piece 11 After the previous chain piece 11 is folded in half, pass through the corresponding two through holes 1111 and connect together in series.

[0021] In this embodiment, since the adjacen...

Abstract

The invention discloses a chain and an anti-loosening structure of a lamp. The chain comprises a plurality of tandem chain sheets; each chain sheet is formed by folding a metal sheet, the two ends of which are provided with through holes; and the adjacent chain sheets are connected in series together in a mode that the rear chain sheet passes through the corresponding two through holes after the front chain sheet is folded. When the chain with the structure is hoisted, the stressed part between the chain sheets is a bending part of the chain sheets serving as a whole; the bearing capacity of the chain is only related with the material strength and the thickness of the chain sheets; on the premise that the material strength and the thickness meet the requirements, because a notch or a welding point on a common chain does not exist, the chain does not break even in gravity or instantaneous impact, so the chain is more reliable and convenient to use; meanwhile, the chain is more convenient to assemble and disassemble in an active buckling mode of assembly by means of bending of the chain sheets; and when the chain structure is applied to the anti-loosening structure of the lamp, the lamp is firmer and more reliable to hoist.

Description

technical field [0001] The invention relates to a lifting piece, more specifically, to a chain and a lamp anti-loosening structure. Background technique [0002] Existing chains are generally formed by connecting multiple metal rings in series. When connecting in series, a gap needs to be opened on each metal ring. After connecting in series, the gap is fastened or welded. When the chain with this structure is hoisted, the notch is a weak link under force. When the chain is subjected to gravity or instantaneous impact, the fastened notch will open. Even if it is welded together, the notch will still break. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a chain with good load-bearing effect, not easy to break, safe to use and reliable. [0004] In order to solve the above technical problems, the technical solution of the present invention is to provide a chain, which includes a plurality of chain pieces connecte...
