Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
A height-adjustable wooden sofa comprises a sofa seat board 2, a sofa back board 1, armrests 3 and a height adjusting mechanism 6, wherein the sofa seat board 2 is horizontally arranged, and the sofa back board 1 is vertically connected with the rear side of the sofa seat board 2; the handrail 3 comprises a handrail table 4 arranged along the horizontal direction and two supporting columns 5 arranged along the vertical direction; the supporting columns 5 are respectively fixedly connected with two sides of the lower surface of the handrail 3; the two sides of the sofa seat board 2 are respectively and fixedly connected with the supporting columns 5 vertically, so that the purpose of fixing the sofa seat board 2 and the armrests 3 together is achieved, and the lower parts of the supporting columns 5 are provided with inner thread grooves 7 with downward openings.
Four height adjusting mechanisms 6 are arranged, each height adjusting mechanism 6 comprises a base 11, the bases 11 are horizontally arranged, external thread struts 13 are rotatably arranged above the bases through bearings, and the upper parts of the external thread struts 13 are in threaded connection with the internal thread grooves 77; the lower part of the external thread strut 13 is provided with an external gear 14;
