Electric machinery stretching device

Abstract

The invention provides an electric machinery stretching device which solves the technical problems that in an existing stretching device, a motor is connected with a motor front connection tube, fro-back movement of the motor needs to occupy larger installation space, a use effect is poor and the like. The electric machinery stretching device comprises a base and a function frame, wherein the function frame comprises power rods which are symmetrically arranged on the base, the power rods are arranged on the front side of the base, and a driving mechanism for driving the power rods to swing back and forth is arranged on the base; the driving mechanism comprises a linear push rod guiding rail motor, an installation rod and an installation seat; the linear push rod guiding rail motor comprises a motor head, a guiding rail and a sliding block, the sliding block is movably connected to the guiding rail, the guiding rail is connected to the motor head, the motor head is in hinge connection with the installation seat through a first detachable structure, the installation seat and the base are connected, the installation seat is arranged on the rear side of the base, the sliding block is in hinge connection with the middle of the installation rod through a second detachable structure, and the end of the installation rod is connected with the power rods. The electric machinery stretching device disclosed by the invention has the advantage of good use effect.

Description

technical field [0001] The invention belongs to the technical field of sofas, and relates to an electromechanical stretching device. Background technique [0002] At present, many furniture such as lounge chairs and sofas are equipped with electromechanical extension devices, on which backrests, seat cushions and leg rests are installed, and electromechanical extension devices are usually a combination of various mechanical connectors. The components are operable to provide various comfort features, such as independent reclining movement of the seat assembly, and actuation of the extendable leg rest assembly and associated tilting of the chair frame. [0003] After searching, for example, Chinese patent literature discloses an electromechanical stretching device for a movable sofa [application number: 201420245376.4; publication number: CN 203852053U]. This electromechanical stretching device for a movable sofa includes a mechanical stretching device and an electric device....

AI Technical Summary

Problems solved by technology

[0004] Although the cost of the stretching device disclosed in this patent is relatively low, the motor in the stretching device is connected to the connecting pipe in front of the motor. The motor needs to move back and forth to occupy a large installation space, and the use effect is poor. Therefore, an electric motor is designed. Mechanical stretching devices are necessary
