The utility model content
The utility model provides a kind of eccentric wheel fine setting swivel chair pallet, it mainly is to solve existing in prior technology swivel chair pallet in use, the power of torque spring is unadjustable, and can not satisfy spring force to the swivel chair pallet has the technical problem of regulating the client that requires etc.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Eccentric wheel fine setting swivel chair pallet of the present utility model, comprise base, the base bottom is provided with lid, lid portion inside is hinged with seesaw by first bearing pin, and described seesaw is fixed with extension spring by second bearing pin, and the extension spring other end is fixed with adjustment sheet, adjustment sheet is hinged on the lid by the 3rd bearing pin, cross-under has adjusting rod on the lid, and adjusting rod is connected with eccentric wheel, eccentric wheel contact adjustment sheet.Lid can be an aluminium lid, and eccentric wheel is fixed on the aluminium lid after passing handwheel by adjusting rod, and when adjusting rod rotated, this moment, eccentric wheel and then rotated, and when eccentric wheel pushes adjustment sheet, will spur extension spring, thereby finish the extension spring trim process.
As preferably, described adjustment sheet is " C " type, its middle part contact eccentric wheel, and eccentric wheel is a hexagon, has 4 on it and effectively regulates limits.When eccentric wheel rotates, effectively regulate the limit for 4 on it and can both push adjustment sheet pulling extension spring, thereby realize many gears adjustings.
As preferably, effectively regulate the excentric 8～12mm that are of a size of of back gauge for described 4, wherein adjacent both sides differ 1mm respectively with distance apart from the center.Eccentric 4 distances of effectively regulating limit and center increase 1mm successively, and adjustable distance is identical, every switching one side, and the flexible 2mm of adjustment sheet pulling extension spring can regulate 4 grades altogether, and the longest pulling of extension spring 8mm makes adjusting quicker, more convenient.
As preferably, described base two ends are fixed by the 4th bearing pin, the 5th bearing pin and lid respectively, and lid has mounting hole, and the 4th bearing pin passes mounting hole, and the 5th bearing pin is installed with seesaw simultaneously, assembles fairly simple.
As preferably, described adjusting rod outer end is connected with handwheel, by handwheel rotary regulating lever comparatively easily.
Therefore, the utlity model has the governor motion that extension spring can be finely tuned voluntarily when swivel chair base and backrest remain static, have adjusting lighter, quicker, more humane, characteristics such as simple and reasonable for structure.
