Preferably, the straight spur gear is engaged with tooth plate, is toothed around on the tooth plate, and on tooth plate the gear teeth length
Degree is equal with the height of tooth plate.
In the utility model, user opens driving motor when using this device, and first rotating shaft drives turntable rotation,
It then drives first connecting rod and second connecting rod to move, that is, drives the first limiting plate to move up and down in cavity, since connecting plate is recessed
In slot, the restriction effect with left and right directions, therefore the first limiting plate will not generate displacement in the horizontal direction, drive straight tooth column
Gear moves in the vertical direction, since the length of the gear teeth on tooth plate and the height of tooth plate are equal, that is, ensures straight tooth column tooth
Wheel engages always with tooth plate, and when back cushion is not bonded the waist of user, user utilizes the strength of waist to the side of back cushion
It slightly exerts oneself, then straight spur gear rotation is driven by connecting plate and the second shaft, then can adjust the height of back cushion both sides
Degree, the waist of user is bonded with this.The utility model overcome present in traditional computer chair without lumbar support or waist
The defect that can not be adjusted is supported, it makes back cushion in rotation by the design of adjustable lumbar support, and lumbar support can be close
It is bonded waist, be not in hanging or hanging part phenomenon has higher economic profit with extensive market application prospect
Benefit.
