Abstract
The utility model relates to a chair tray with an adjustable elastic force and overcomes the defects that a torsion force of a torsion spring is lowered due to the fact that a tilting elastic force between a tray big plate and a tray middle plate is supplied by the torsion spring on the hinged portion between the tray big plate and the tray middle plate, and the torsion force can not be easily adjusted in the prior art. The chair tray with the adjustable elastic force comprises the tray big plate and the tray middle plate, wherein the tray big plate is hinged with an internally arranged spring mechanism, one end of the spring mechanism abuts against the interior of the tray middle plate, the spring mechanism comprises a T-shaped support, a spring sleeved on a vertical part of the support, and a worm wheel which is in spiral connection with the end portion of the vertical part of the support and presses the spring tightly, a worm rod meshed with the worm wheel is arranged inside the tray middle plate, and the worm rod is connected with an elastic adjusting handle extending out of the tray middle plate. As the spring mechanism provides the elastic force for chairs, the elastic force can be conveniently adjusted by adjusting the length of the spring. The worm wheel of an elastic force adjusting mechanism is in spiral connection with a middle rod of the support, so rotating the worm wheel can change the distance between a top head and a transverse part of the support so that the length of the spring can be changed and adjustment of the elastic force can be achieved.
