Description

Technical Field

[0001] The utility model relates to the technical field of sofas, in particular to a sofa with adjustable armrests. Background Art

[0002] A sofa is a cushioned multi-seat chair. It is a backrest chair equipped with springs or thick foam plastics, with armrests on both sides. It is a kind of soft furniture.

[0003] In the prior art, there is a functional sofa with adjustable armrest spacing, which is published as CN220713438U. The sofa adopts the scheme of "comprising: a frame, comprising a support seat, a seat is fixedly connected to the surface of the support seat, a backrest is movably connected to the surface of the seat, and an armrest is slidably connected to the outer surface of the seat; a folding mechanism, comprising a control motor, and the control motor is fixed to the inner side of the seat". The scheme realizes the separation of the insertion rod and the adjustment groove through the connection of the pinch rod and the insertion rod, so that the backrest can be folded on the seat, and the seat cushion on the seat will not affect the angle of the backrest. The overall size of the support seat can be changed to facilitate transportation. Under the connection of the pull rope and the movable disk, the position of the movable disk in the connecting rod is changed, thereby changing the action position and angle of the push rod in the connecting rod, so as to achieve the separation of the push rod and the seat, and realize the movement and fixed control of the position of the connecting rod.

[0004] However, the above scheme still has some shortcomings. For example, although the sofa can adjust the distance between the two armrests during actual use, the actual adjustment process requires personnel to pull and turn a small pull plate, and the operation is very inflexible. Moreover, when the sofa is used by people with taller heights or different habits, the height of the armrests cannot be adjusted. That is, the technical scheme proposed by the above patent technology has the defect that the distance and height of the sofa armrests cannot be automatically adjusted.

[0005] In view of this, the utility model provides a sofa with adjustable armrests. Utility Model Content

The spacing adjustment component 400 includes a rectangular cavity opened inside the sofa base 100, and two symmetrical sliding plates 401 slidably arranged on the inner wall of the rectangular cavity. Two symmetrical L-shaped support tubes 402 that penetrate the sliding plate 401 are fixed to the side of the sliding plate 401. Two sliding holes are opened on the inner walls on both sides of the rectangular cavity, and the inner walls of the two sliding holes are respectively slidably connected to the outer surfaces of the two L-shaped support tubes 402.

[0039] The sofa armrests 300 are arranged at the ends of two L-shaped support tubes 402, and the spacing adjustment assembly 400 also includes a double-axis motor 403 fixed on the bottom wall of the rectangular cavity, and threaded columns 404 fixed on the two output ends of the double-axis motor 403, and the sides of the two sliding plates 401 are respectively provided with threaded holes threadedly connected to the outer surfaces of the two threaded columns 404;
