The utility model content
The utility model technical issues that need to address provide a kind of pulley 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:
Pulley of the present utility model is regulated the swivel chair pallet, comprise base, it is characterized in that described base both sides are connected with left sliding panel respectively, right sliding panel, left side sliding panel, the front and back end of right sliding panel respectively has a chute, left side sliding panel, be provided with first pulley in the chute of front end on the right sliding panel, be connected with first bearing pin between two first pulleys, left side sliding panel, be provided with second pulley in the chute of rear end on the right sliding panel, be connected with second bearing pin between two second pulleys, cross-under has seesaw on second bearing pin, left side sliding panel, the rear end of right sliding panel is provided with the inclined-plane, the place, inclined-plane is provided with the middle base that is obliquely installed, the upper surface of middle base is provided with two the 3rd pulleys, is connected with the 3rd bearing pin between two the 3rd pulleys.Individual inclined-plane is arranged on the middle base, and it is identical with the inclined-plane of left sliding panel, right sliding panel just, and the 3rd pulley on the 3rd bearing pin is slided on the inclined-plane.When pressing the seesaw activity, the pulley that can drive on first bearing pin and second bearing pin slides in chute, and the 3rd pulley that drives in passing on the 3rd bearing pin slides on the inclined-plane 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 middle base inclined-plane 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 middle base inclined-plane is also corresponding little, thereby the power that presses seesaw is also 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, the angle on described left sliding panel, inclined-plane, right sliding panel rear end is 30～40o, makes adjusting more comfortable.
As preferably, the chute of described left sliding panel, right sliding panel front end tilts to the front upper place, and the chute of left sliding panel, right sliding panel rear end tilts to the front lower place, can be when seesaw press down, and pulley is more smooth and easy slidably.
As preferably, the diameter of described first pulley is 25mm～35mm, and the diameter of second pulley and the 3rd pulley is 25mm～35mm, makes adjusting quick and portably.
Therefore, the utlity model has according to human body weight and regulate base and chair back pulley governor motion voluntarily, regulate characteristics such as lighter, quicker, more humane, simple and reasonable for structure.
