Specifically, fig. 1a and 1b are schematic views of an embodiment of a suspension back frame according to the present invention, which mainly show the back structure:
The back structure of the suspension back frame comprises a vertical rigid frame 1, a supporting rod 2 is arranged at the lower end of the vertical rigid frame 1, and a sliding rod 3 is arranged at the upper end of the vertical rigid frame 1. The support rod 2 is fixedly connected with the vertical rigid frame 1 and is used for bearing downward load when the hanging back frame carries heavy objects. The sliding rod 3 is fixedly connected with the vertical rigid frame 1 and is used for bearing force which is perpendicular to the direction of the sliding rod 3 and is generated by the fact that the gravity center deviates from the supporting rod 2 when the hanging back frame carries a heavy object. In order to ensure the stability of hanging the back frame to carry the heavy objects, the support rods 2 are at least arranged in two, left and right opposite sides are distributed, the load is stably borne, and the overturning is prevented, and the sliding rods 3 are at least arranged in two, left and right opposite sides are distributed, the force vertical to the sliding rods 3 is stably borne, and the overturning is prevented.
In some embodiments (as shown in fig. 1 b), the vertical rigid frame 1, the support bar 2, and the sliding bar 3 are a unitary structure, which is more convenient to produce.
In an embodiment, the first clamping assembly includes a hanging strip 61 and a fixing connection piece 62, the upper end of the hanging strip 61 is connected to the rear side of the waistband 63, the fixing connection piece 62 is disposed on the hanging strip 61, and the supporting rod 2 is connected with the hanging strip 61 through the fixing connection piece 62, so as to realize flexible hanging connection of the vertical rigid frame 1 and bear the load of the hanging back frame in the downward gravity direction.
