The utility model content
The utility model technical issues that need to address provide a kind of axis of rolling and regulate the swivel chair pallet, and it mainly is that the governor motion that solves existing in prior technology swivel chair pallet can not satisfy the technical problem of people's use of different weight with a swivel chair pallet.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
The axis of rolling of the present utility model is regulated the swivel chair pallet, comprise base, middle base, seesaw, it is characterized in that described base rear end has first mounting hole, the base middle part has second mounting hole, first mounting hole by first axis of rolling with base, middle base, seesaw cross-under together, second mounting hole by second axis of rolling with base, middle base cross-under together, the front end of middle base has the 3rd mounting hole, and the 3rd mounting hole by the 3rd axis of rolling with base, middle base cross-under together.When pressing the seesaw activity, meeting drives first axis of rolling and second axis of rolling rolls in the mounting hole of base, drives the 3rd axis of rolling in passing and rolls in the mounting hole of middle base, is welded with Taper Pipe on the middle base, be connected middle base transfixion when seesaw is movable with atmospheric pressure pole.When the power on being applied to base is big, the power that presses on the 3rd axis of rolling strengthens, the power that is pressed in simultaneously on the middle base mounting hole is also corresponding big, thereby the power that presses seesaw also needs greatly, when the power hour that applies on the base, the power that presses on the 3rd axis of rolling is also little, the power that is pressed in simultaneously on the middle base mounting hole is also corresponding little, thereby the power that presses seesaw is also corresponding little, promptly can finish the power of regulating base and backrest automatically according to human weight, thereby realize being applicable to that with a pallet the people of different weight uses, and realizes the versatility of product.
As preferably, described first mounting hole, second mounting hole, the 3rd mounting hole all are equipped with waist shape lining, and first axis of rolling, second axis of rolling, the 3rd axis of rolling all are through in the waist shape lining, wearing and tearing mounting hole edge when preventing to move.
As preferably, described first mounting hole, the 3rd mounting hole tilt to the front upper place, and second mounting hole tilts to the back upper place, can be when seesaw press down, and the axis of rolling is rollably more smooth and easy.
As preferably, described seesaw is provided with bearing pin, is provided with the disjunctor torque spring between the bearing pin and first axis of rolling, the seesaw after the work can be resetted.
As preferably, the angle of described disjunctor torque spring two arms is the 80-120 degree.
Therefore, the utlity model has the axis of rolling governor motion of regulating the base and the chair back according to human body weight voluntarily, regulate characteristics such as lighter, quicker, more humane, simple and reasonable for structure.
