The specific embodiment
Below in conjunction with accompanying drawing the utility model is made concrete further instruction.A kind of novel chair back height adjuster, it is characterized in that: it comprises the pedestal 2 and the slide block 4 that with seat support 3 be connected fixedly connected with the chair back 1, slide block is installed in the chute in the pedestal and can slides up and down within it, described pedestal is provided with the gear groove 5 of two gang saw dentations, be movably hinged with the first locking button 41 and the second locking button 42 that can be snapped in the gear groove at slide block, be provided with elastic device and self-locking device 6 between two locking buttons, the two ends up and down of described gear groove 5 be respectively equipped with can make that self-locking device 7 locks and unblank on locked groove 51 and the groove 52 of unblanking.
The pivoted housing 43 of the described first locking button 41 and the second locking button 42 is provided with dislocation heavy stand 44, and the locking button can be hinged on the slide block 4 by rivet 45 with swinging.
Described elastic device is the compression spring 7 that is installed in the first locking button 41 and the second locking button, 42 inboards.
Described elastic device is the torque spring that is installed in the first locking button 41 and the second locking button, 42 inboards.The torsion spring snare of torque spring is on rivet.
Described self-locking device 7 is for being arranged on the cylindrical boss 71 on the first locking button 41 and being arranged on arc-shaped slot 72 on the second locking button 42, and the center of circle of described cylindrical boss 71 and arc-shaped slot 72 is positioned on the same circumference.
Described cylindrical boss 71 and arc-shaped slot 72 protrude from the madial wall setting of the first locking button 41 and the second locking button 42.Outstanding design makes the sidewall of arc-shaped slot unsettled, makes it can produce the effect of strain.
The lateral wall of the described first locking button 41 and the second locking button 42 is provided with anticreep boss 45.The anticreep boss is pressed on the surface of slide block, plays outwards to prevent the locking button and guide effect.
The described locked groove 51 of going up is for being arranged on the U-shaped groove of gear groove upper end, and the employing arc transition is connected between the gear groove of U-shaped groove and both sides,
