Description

A health chair

technical field

The invention belongs to the technical field of furniture and relates to a health-care chair.

Background technique

With the popularization of computers and the continuous increase of people's workload, there are more and more sedentary people. The normal human spine has three physiological curvatures at the neck, chest, and waist. When people sit on chairs or sofas, even if they are not working at their desks, they will naturally adopt a bent-back posture under the action of gravity. This is due to the natural posterior tilt of the pelvis and the protrusion of the lumbar spine. In this posture, it will inevitably cause the strain of intervertebral disc fibers and lumbar ligaments over time, induce low back pain, and even protrude lumbar intervertebral disc, compressing nerves and causing leg pain. Similarly, cervical strain can cause cervical spondylosis. Symptoms include pain in the neck, shoulders, and arms, difficulty moving the legs and feet, dizziness, and even fainting. Because there are no symptoms in the early stage, people do not realize the danger of this posture. Scientific research has confirmed that long-term sedentary is the main cause of spinal decline. Most modern chairs are not ergonomic. Sitting for a long time has caused many people to have prominent cervical and lumbar problems.

Contents of the invention

In order to overcome the deficiencies of the prior art, the present invention provides a comfortable and reliable health-care chair that conforms to ergonomics and can adjust multiple parts according to its own needs, effectively avoiding cervical spondylosis and lumbar spondylosis.

In order to achieve the above object, the technical scheme of the present invention is as follows:

A health-care chair, including chair legs, a chair surface and a chair back, the chair back is frame-shaped, and two vertical rods are installed on the chair back; symmetrical card slots are evenly provided on the vertical rods; the A neck pillow and a lumbar pillow are arranged on the vertical bar; the neck pillow and the lumbar pillow are respectively provided with connectors and fixed on the vertical bar.

The connectors described above include a pair of fixed pieces, a pair of fixed rods and a spring; the fixed pieces are provided with screw holes; the neck pillow and the lumbar pillow are respectively threaded with the fixed pieces with bolts or screws; A D-shaped slot is provided in the middle of the fixed piece, a spring is provided in the middle of the D-shaped slot, and a fixed rod that engages with the draw-in slot on the vertical bar is provided at both ends of the spring.

The above-mentioned fixed rods are all provided with protruding rods.

The above-mentioned chair surface is also provided with a cushion, and the cushion is connected and fixed with the chair surface in a conventional manner.

The above-mentioned neck pillow and the middle part of the lumbar pillow are all provided with grooves.

The card slot mentioned above is a square slot or a circular slot.

The above-mentioned chair back and the lower ends of the two vertical rods are equipped with telescopic sleeve mechanisms; the telescopic sleeve mechanisms include an outer sleeve, an intubation tube and a fastening screw; one end of the intubation tube is fixed on the chair surface , the other end can be freely retracted in the outer casing and fixed by the fastening screw on the outside of the outer casing.

working principle:

When in use, the neck pillow and lumbar pillow are respectively threaded and fixed with the fixing piece on the connecting piece, first press the dialing lever, the spring shrinks, thereby shortening the length of the fixing lever, place the fixing lever in the slot of the vertical rod of the back of the chair, and loosen it. When the lever is opened, the spring recovers, so that the fixed rod recovers its natural length, and is engaged in the draw-in slot on the vertical rod, so that the neck pillow or lumbar pillow can be reliably fixed on the vertical rod of the chair back. There are many pairs of zigzag slots on the vertical rod, which can adjust the position of the movable neck pillow or waist pillow according to the different heights and needs of the human body, and can also adjust the telescopic sleeve mechanism Ⅰ and telescopic sleeve mechanism Ⅱ. There are grooves on the neck pillow and lumbar pillow, and there is a cushion on the seat surface, which conforms to ergonomics and is convenient and comfortable to use.

Compared with the prior art, advantages and beneficial effects of the present invention are as follows:

1. The present invention is equipped with a neck pillow and a lumbar pillow, which can relieve the fatigue of sitting for a long time, reduce the symptoms of backache and neck pain, and can be adjusted up and down according to the height of different people, which is ergonomic.

2. The neck pillow and lumbar pillow of the present invention are detachably connected to the vertical bar through the connecting piece, which is easy to replace and clean, and is clean and hygienic to use.

3. The structure of the present invention is simple and reasonable, the connection is reliable, and it is convenient to move and adjust the position. It is suitable for various occasions such as homes and offices.
