TECHNICAL FIELD

[0001] The present utility model relates to the technical field of a connecting part and a piece of furniture equipped therewith, in particular to a snap-in insert and a bed frame equipped therewith. STATE OF THE ART

[0002] Existing bed frames consist of a main body (including a headboard, bedside panels on both sides, and a bed end panel at the rear end), with adjacent main body parts of the bed frame directly connected by connectors. The position of the connectors is prone to deviation, so problems such as loosening, slippage, and even connection failure may occur due to insufficient connection accuracy, resulting in the bed frame main body being prone to abnormal noise or disintegration during use. It may then be necessary to adjust the arrangement position of the respective connector for reconnection or even replace the bed frame main body. This not only affects the normal use of the bed frame main body but also increases the risk and cost of replacing the bed frame main body. CONTENT OF THE PRESENT UTILITY MODEL

[0005] As a further improvement and supplementation of the above technical solution, the present utility model adopts the following technical measures: the outer side wall of the insert body has a circular-arc cylindrical surface and the circumferential rotation stop structure, wherein the circumferential rotation stop structure is a flat cut surface. The circular-arc cylindrical surface is advantageous for facilitating assembly during manufacturing, processing, and use and reducing the possibility of stress concentration of the insert body, while the flat cut surface is advantageous for effectively achieving the purpose of the circumferential rotation stop.When the snap-in insert is applied to the bed frame, the inner wall of the insert mounting cavity on the main body of the bed frame is positively fitted to the outer side wall of the insert body, which also features a circular cylindrical surface and a flat cut surface.
