Description

Technical Field

[0001] The utility model relates to the technical field of iron art beds, and specifically relates to a stable iron art bed. Background Art

[0002] Iron art beds are popular among the public because of their environmental protection, simple fashion and convenient disassembly and assembly. They are also one of the first choices for beds in families in today's society. Their lines are smooth, and different colors match the indoor decoration, giving people a noble and warm feeling. However, the disadvantages of iron art beds are also obvious. The connection methods of various parts of the bed frame of the iron art bed greatly affect the stability and sound insulation of the bed frame. The existing connection method of the iron art bed frame is to directly screw the screws on the bed legs, and the disadvantages are as follows: the weight bearing of the bed body is all on the screws, which is easy to make a squeaking sound, affecting the sleep quality. After a long time, the screws may become loose, and the weight bearing may become unstable.

[0003] The Chinese patent discloses an iron art bed (authorization publication number CN 206548212 U). The weight bearing of the iron art bed provided by this patented technology is not on the screws, ensuring the stability and sound insulation of the iron art bed. At the same time, the height of the bed frame can be adjusted to meet the usage requirements of different people. Because all the screws are inside, there are no traces of damage on the outer surface of the fixed bed body, making the bed body beautiful and generous. However, the screws connecting the metal feet and the side rods are exposed, which is not convenient for installation. Therefore, the utility model provides a stable iron art bed to solve the problems raised in the above background art. Content of the Utility Model
