And under the condition that the user keeps sitting posture for a long time, sweat can appear at the position that the cervical vertebra contacts with the arc-shaped headrest 801 because of long-time laminating, and it can lead to user's discomfort, can start the air pump 807 this moment, and the air pump 807 can transmit the outside air to the position that the cervical vertebra contacts with the arc-shaped headrest 801 through connecting trachea 806, ventilation cabin 8012, isolation air pipe 805 to make the cervical vertebra keep dry and comfortable state, through designing two cabins, both can realize that the laminating of arc-shaped headrest 801 supports, can also realize ventilative function and avoid secondary injury, effectively improve the comfort level of seat, make the prevention effect obtain further improvement.
And before and during the use of the chair, the chair can be adjusted by the condition and the feeling of the user; the height and the angle of the arc-shaped headrest 801 are adjusted, wherein the arc-shaped headrest 801 can rotate by taking a multi-gear adjusting block 703 as a center and a connecting rod 702 as a base through a connecting column 802, a rotating groove 8021 and a rotating hole 8022, so that the angle adjustment of the arc-shaped headrest 801 is realized, and the angle can be fixed or adjusted by screwing and unscrewing a locking bolt 803.
The height adjustment of the arc-shaped headrest 801 is realized by the up-and-down movement of the lifting rod 701, the lifting rod 701 slides up and down along the inner wall of the sleeve joint groove 6011, and the locking fixation of the lifting rod 701 can be realized by the mutual coordination of the telescopic fixed block 603, the compression block 604, the telescopic spring 605, the telescopic groove 6013 and the fixed hole 7011.
In addition, when the related structure is required to be maintained in the later maintenance of the chair, the locking mechanism 6, the connecting mechanism 7 and the supporting mechanism 8 can be disassembled; the lifting rod 701 is moved upwards to a state that the top end of the limiting block 705 is attached to the bottom end of the fixed sleeve 601, at the moment, the bottom end of the guide block 704 is flush with the top end of the fixed sleeve 601, namely, the guide block 704 is separated from the limiting groove 6012, at the moment, the lifting rod 701 is rotated to enable the limiting block 705 to rotate below the limiting groove 6012, then the limiting block 705 can be driven by the lifting rod 701 to move upwards along the inner wall of the limiting groove 6012, and when the limiting block 705 moves to the upper side of the fixed sleeve 601, the lifting rod 701 is detached, and the separation of the locking mechanism 6 and the connecting mechanism 7 is realized; unscrewing the locking bolt 803 completes the separation of the support mechanism 8 and the connection mechanism 7.
The foregoing description is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical solution of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
