Electric mechanical stretching device applied to movable sofa

Abstract

The invention relates to the technical field of sofa stretching devices, and discloses an electric mechanical stretching device applied to a movable sofa, the electric mechanical stretching device comprises base frames, first placing plates are fixedly mounted at the top ends of the two adjacent base frames, and a supporting box, an air cylinder, a first supporting plate and a second motor are fixedly mounted at the top end of each first placing plate; through rotation of a second motor, the second motor can drive a second threaded column to rotate, the second threaded column can drive a second moving block to move by height when rotating, in this way, the second moving block can drive a fourth pin shaft base to move by height when moving, and through mutual cooperative use of third limiting blocks, the height of the fourth pin shaft base can be adjusted. A fourth pin shaft seat can drive a second sliding block to slide on the outer side of a third supporting column through a first connecting rod and a fifth pin shaft seat, and a foot pad plate is driven to change the angle through matched use of a first pin shaft seat, so that angle adjustment of the foot pad plate is achieved, and the comfortable use effect of the sofa is achieved.

Description

Technical field [0001] The present invention relates to the technical field of sofa stretching device, specifically a kind of electric mechanical extension device applied to the movable sofa. Background [0002] At present, many consumer health care places in life in the convalescence due to the process of the need for people will switch between sitting and lying fingers, in the past are needed to be people back and forth between the chair and the bed, it seems too troublesome, so there is a stretchable sofa, the current device although the sofa to achieve the electric stretch function, but has the common disease of the stretch sofa, that is, for the protection of the front stretch frame, usually when used, the front frame is only used to support the part that will not be too heavy, and it can not carry too much weight due to the stretching reasons. However, in real use, this weight is not easy to grasp, so it often causes damage to the front shelf, and the height of the sofa ca...

Problems solved by technology

[0002] At present, in many consumer sanatoriums in life, people will switch between sitting and lying fingers due to the process of recuperation. In the past, people needed to switch back and forth between chairs and beds, which seemed too troublesome, so there is a stretchable Although the current device enables the sofa to realize the electric stretching function, it has the common problem of stretching the sofa, which is the protection of the front stretching frame. Usually, the front frame is only used to support the parts that will not be too heavy. It can't carry too much weight due to stretching, but in actual use, this weight is not easy to grasp, so it often causes damage to the front frame, and the height of the sofa cannot be adjusted
