Further improved as the utility model, the straight line output unit is arranged under the fixed supporting beam
Side, the movement portion and the end of the extension are hinged.
Further improved as the utility model, the lead is flexibly connected with the third connecting rod, described to lead
It can be rotated to column relative to the third connecting rod.
Further improve two, including two sets of link mechanisms being arranged in parallel as the utility model, the fixed part with
The fixation supporting beam connection of two sets of link mechanisms.
Further improved as the utility model, the movement portion while the extension with two sets of link mechanisms
End it is hinged.
Compared with the prior art, the utility model has following beneficial technique effect：
A kind of hoisting mechanism, including link mechanism, the link mechanism include fixed supporting beam and are propped up with the fixation
The hinged first connecting rod of beam is supportted, the other end and the second connecting rod of the first connecting rod are hinged, the other end of the second connecting rod
It is hinged with lifting unit, being also horizontally disposed with along the length direction of the fixed supporting beam in the fixed supporting beam has guide groove,
One end of third connecting rod is provided with lead, and the lead inlay card is in the guide groove and can be along the guide groove water
Translation is dynamic, and the other end of the third connecting rod and the lifting unit are hinged, the position between the first connecting rod both ends
Position between the third connecting rod both ends is hinged.The lead of third connecting rod is promoted to be moved left and right in guide groove
The elevating movement of lifting unit is can be realized as, this structure has been fully met in the backrest adjustment of face sofa, sofa backrest
The gap site of side needs a component lifted to be filled into the gap formed between sofa adjustment rear waist and sofa backrest,
Still there can be the requirement of relatively good user experience so as to ensure user after sofa adjustment.At the same time itself rational in infrastructure and
Occupy little space, can very easily set into furniture such as sofas.Hoisting mechanism is further included to be connected with the third connecting rod
The linear motion output unit connect.The linear motion output unit includes fixed part and the fortune moved relative to the fixed part
Dynamic portion, the movement portion is connected with the third connecting rod.Movement portion drives third connecting rod movement to can be realized as foregoing lifting
Movement, so by controlling linear motion output unit just can easily control elevating movement.The third connecting rod further includes
The extension and the body of top being arranged on below the lead, the extension are connected with the movement portion.Described
Body portion and extension setting in a certain angle.Angle between the body and the extension is right angle.This knot
Structure reduces the volume of hoisting mechanism, facilitates its installation, while accepting uniformly such a construction ensures entirety, extends use
Service life.The straight line output unit is arranged on the lower section of the fixed supporting beam, the movement portion and the end of the extension
It is hinged.The lead is flexibly connected with the third connecting rod, and the lead can be relative to the third connecting rod
Rotate.So so that the operation of hoisting mechanism is more smooth, the appearance of interim card situation is avoided.Hoisting mechanism is parallel including two sets
The link mechanism of setting, the fixed part are connected with the fixation supporting beam of two sets of link mechanisms.The movement portion at the same time with
The end of the extension of two sets of link mechanisms is hinged.Two sets of link mechanisms pass through a linear motion output unit
To drive, it can ensure that lift adjustment process is more reliable and more stable.
