Technical Field

The invention relates to a lifting device, in particular to a dynamic adjusting method and a dynamic adjusting device for a projector position.

Background

The use rate of the projector in offices and families is higher and higher, so that people cannot leave the projector in work, life and study. The time consumed by people on a television and a computer every day is counted by figures for three to four hours, and a comfortable posture that the head is not raised or lowered is difficult to achieve when a projector screen is watched. When the device works for a long time, the device needs to move the head and neck for 1 hour, so that ligament and muscle of the neck can be properly rested, the operation and the rest are combined, the exercise of the muscle of the neck and the shoulder is strengthened, and the excessive backward bending or the excessive forward bending of the head and neck is avoided. For long-term workers on a desk, the head and the neck are purposefully rotated left and right for a plurality of times within 1-2 hours, the head and the neck are rotated gently and slowly during rotation, the maximum movement range in the direction is reached, and staff in a workplace are difficult to take out time to rest and exercise.

If we sit in the office for a long time, our posture, in the case of long-term malaise, can cause muscle imbalance, or we have the first bone in our neck, we have 7 bones in our neck, and these 7 bones are fixed to physiological positions, and this bone position is abnormal for a long time and can stress nerves over time. We know that this problem exists, first, to keep our body position as correct as possible; secondly, the patient does not stay in the same poor posture for too long, which is a good prevention; third, we need to do some more exercise, neck exercise, correct exercise to strengthen our muscle strength, which we can bear our head if it is strong enough, and it does not work over time if we support our head in a bad posture. If the force we are subjected to is not so severe, the conditions of our injury or fatigue are relatively reduced.

For example our projector always has such a position so our movements are with the chin forward, head forward, sternum forward, head up posture. Poor posture is fatigued easily, which often lasts for a long period of time, one day or two days, but after a long time, the recovery is started if the patient is limp and tired.

The projector is in one place, and people sit on the same side, so that the chance of contracting the muscles on the other side is avoided, the muscles on one side are shorter and shorter, and the muscles on the other side are longer and longer, and various neck and shoulder diseases can occur in the past.
