Independent backrest adjusting device of sofa iron stand

Abstract

The invention discloses an independent backrest adjusting device of a sofa iron stand, belonging to the technical field of sofas. The independent backrest adjusting device can achieve the free adjustment of the angle of a sofa backrest, and in the adjustment process, the phenomenon that the transmission structure is stuck is not easy to occur, meanwhile, a rubber gasket is arranged in a sofa ironstand connecting structure, so that the influence of vibration generated in the adjusting process of structures such as an iron base frame on bolts for connection is greatly reduced, the blot is not easy to loosen, the overall connection of the sofa iron stand is more stable and is not easy to loosen, a backrest support is provided with a back cushion filled with a spiral framework and a filling fluff, the possibility that a user is knocked in the sofa using process is reduced, meanwhile, the multiple pieces of filling fluff are interwoven and entangled together to form multiple cavities, andthe influence of vibration and noise generated by vibration generated by structural adjustment of the iron base frame and the like on the user can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of sofas, in particular to an individual backrest adjustment device for a sofa iron frame. Background technique [0002] The sofa is one of the seats that people generally like. It is widely used in reception rooms, hotels, homes and leisure places. The main components of the sofa include steel skeletons, cushions and decorative skins. Among them, the steel skeleton is the most important for maintaining the shape of the sofa. Parts, while structures such as cushions and decorative skins are designed to make the sofa more comfortable and enhance the user experience. [0003] In particular, bolts and nuts are often used to achieve fixed connections between steel frameworks. In order to prevent the bolts and nuts from loosening, anti-skid pads are usually installed between the screw heads of the bolts and the iron frame to prevent the bolts and nuts from slipping and loosening.

AI Technical Summary

Problems solved by technology

[0004] Existing sofa electromechanical devices use a set of motors to realize the mutual switching between sitting, standing, and lying positions of the sofa. Since the existing sofa transmission structures are mostly realized by structures such as rack and pinion or ratchet, the above-mentioned transmission structure Stepless adjustment cannot be realized during the transmission process. During the adjustment process, the transmission structure is likely to be stuck, or the transmission structure emits excessive noise, which affects the user's experience. Moreover, the sofa backrest adjustment angle is limited and cannot be adjusted separately, which affects the The overall comfort of the sofa cannot meet the needs of the majority of users, especially the steel frame is prone to loud noises during the transmission process of rack and pinion or ratchet structures, which seriously affects the user experience
