Problems solved by technology

But this kind of sofa has higher requirements on the strength of the rigid rod 108, and the rigid rod 108 will be bent or even broken after long-term use; secondly, because the electromagnetic reversing valve 203 adopts the function of an O-shaped slide valve, the magnets at both ends are powered off and the oil pump does not work. The pressure on the port P of the reversing valve 203 is too high when it is stopped, which may easily cause damage to the electromagnetic reversing valve; in addition, the sofa can only be powered by a DC power supply, so the scope of application is relatively narrow

Embodiment Construction

[0016] Such as figure 1 As shown, the height-adjustable sofa of the present invention has a sofa body 1, and the sofa body 1 includes a sofa cushion 2, a sofa backrest 3 and an armrest 4, a sofa base 5, and the sofa base 5 is located below the sofa cushion 2, and the sofa base 5 A height adjustment mechanism 100 is arranged inside.

[0017] The height adjustment mechanism 100 includes a hydraulic cylinder 201 and a linkage mechanism driven by a piston rod 210 of the hydraulic cylinder 201 . The hydraulic cylinder 201 is horizontally fixed at the middle part of the sofa base 5 . as attached figure 2 As shown, the obtuse angle vertex of the triangular rigid support 108 is fixedly connected with the extended end of the piston rod 210 of the hydraulic cylinder 201, and the other two vertices are fixedly connected with the rigid middle rod 107a on both sides of the sofa and the midpoints 108a and 108b of the rod 107b. The lengths of the two sides of the triangular rigid support...

Abstract

The invention relates to an electronically-controlled hydraulic sofa with adjustable height, which comprises a sofa body (1), a height adjusting mechanism (100), a hydraulic control system and a control circuit. A sofa cushion can adjust the height through the effect of a connecting bar in the height adjusting mechanism; the height adjusting mechanism is controlled by a hydraulic control system and a person using the sofa can randomly control the height of a sofa seat through simple pressing operation, thus being convenient for people with different heights, the old or disabled to use.

Description

technical field [0001] The present invention generally relates to a height-adjustable sofa, and more specifically, the present invention relates to a height-adjustable sofa that is actuated by electric control hydraulic pressure in public places or at home. Background technique [0002] At present, most existing sofas cannot be raised and lowered. People with different heights have different requirements for the height of the sofa. The above-mentioned ordinary sofas cannot meet the needs of people with different heights. Some handicapped people have difficulty standing up from the sofa, so there is a need for a height-adjustable sofa. [0003] In the prior art, there is a sofa whose height is adjusted by electronically controlled hydraulic means, as described in Chinese patent application CN101167619A. But this kind of sofa has higher requirements on the strength of the rigid rod 108, and the rigid rod 108 will be bent or even broken after long-term use; secondly, because t...
