Description

Technical Field

[0001] The utility model relates to the technical field of furniture rotating mechanisms, in particular to a rotating sliding plate for sofa armrests. Background Art

[0002] With the improvement of living standards, people have put forward more requirements for the functions of furniture, and many functions and structures that are different from traditional models have emerged. For example, the armrests of a sofa can be transformed into seats by rotation and other means, which plays a role in expanding the sitting surface and can be used by more people. To achieve this function, a certain rotation mechanism or other mechanical structure is required, such as a sliding rotating disk disclosed in the existing patent 202021696557.0, in which, in the initial state, the positioning pin is stuck in the slot to fix the rotating plate. When rotation is required, the slider is pushed away from the positioning pin. At this time, the spring is gradually stretched, and then the rotating plate is rotated so that the other slot on the rotating plate faces the positioning pin. Then, under the action of the spring, the slider drives the rotating plate to move in the direction of the positioning pin, and finally the positioning pin is stuck in another slot. However, this patent sets an I-shaped slide rail in the middle and springs on both sides. When sliding, the rotating plate is prone to swing to the left and right of the slide rail. The stability is not high enough and it is also easily damaged after long-term use. Utility Model Content
