Multifunctional sofa iron stand

Abstract

The invention discloses a multifunctional soft iron stand. The multifunctional soft iron stand comprises a base, telescopic assemblies, connecting rods and a driving welding pipe, wherein the base is provided with a motor; both two sides of the base are connected with the telescopic assemblies; each telescopic assembly is provided with a connecting rod; two ends of the driving welding pipe are respectively connected with the connecting rods; the driving welding pipe is connected with a sliding block; the motor is used for pushing the sliding block to drive the driving welding pipe to do reciprocating movement and simultaneously pushing the connecting rods to unfold or fold the telescopic assemblies. Through the way, an existing driving mode is changed by the multifunctional soft iron stand disclosed by the invention; by pushing the connecting rods, functional movement of products is realized, more convenience and flexibility are realized, parts in the existing driving mode are omitted, and the product cost is reduced.

Description

technical field [0001] The invention relates to the technical field of sofas, in particular to a multifunctional sofa iron frame. Background technique [0002] At present, the existing movable sofa mechanical stretching device adopts the roller track structure, and the movable sofa mechanical stretching device adopting the roller track structure is cheaper than the mechanism that relies on the connecting rod device to provide motion to some extent, but the sofa adopting the roller track structure There are some deficiencies in the stretching device: there is a phenomenon of shaking during mechanical stretching, and the synchronization of the left and right mechanical stretching devices is poor, which affects the comfort of the electric sofa; the manufacturing requires tighter tolerances than the connecting rod structure; more frequent use is required The maintenance cost is higher than that of the linkage device. [0003] Some mechanical stretching devices are driven by mot...

Problems solved by technology

[0002] At present, the existing movable sofa mechanical stretching device adopts the roller track structure, and the movable sofa mechanical stretching device adopting the roller track structure is cheaper than the mechanism that relies on the connecting rod device to provide motion to some extent, but the sofa adopting the roller track structure There are some deficiencies in the stretching device: there is a phenomenon of shaking during mechanical stretching, and the synchronization of the left and right mechanical stretching devices is poor, which affects the comfort of the electric sofa; the manufacturing requires tighter tolerances than the connecting rod structure; more frequent use is required maintenance, which is more expensive than a linkage

[0003] Some mechanical stretching devices are driven by motors and sliders, but their connection structures are complicated, many parts are used, the weight of the whole machine is large, and the product cost is also high
