According to above-mentioned utility model design, the utility model adopts following technical proposals:
A kind of chair stool stabilometer, comprise framework, moving beam, loading head parts and load headstock, described moving beam coordinates with a moving leader on described framework by being arranged on the linear bearing at its two ends, load headstock and be installed on moving beam, loading head parts are fixed on and load on headstock.
Described framework is that aluminium section bar lower and upper cross-member and left and right pillar connect and compose a rectangular parallelepiped framework, has a base plate to be installed on the crossbeam of base of frame; Described moving leader is installed on below the entablature of framework, has a test specimen fixed block to be threaded connection and is fixed on base plate.
Described moving beam is installed on the moving leader of framework, totally 2 ~ 5; There is line slideway to be installed on moving beam.
Described loading head parts comprise a pull bar and extension rod; Employing is threaded; Pull bar 9 lower ends are connected with scale pan, have counterweight to be put on scale pan, scale pan and pull bar chain connection; Counterweight comprises 1 initial counterweight, 17 10kg counterweights, and 2 5kg counterweights, 2 2.5kg counterweights, wherein initial counterweight and loading head and correlated parts quality sum are 10kg.
The structure of described loading headstock is: load headstock inside straight-line guide rail slide block is housed, coordinate with line slideway on moving beam; And there is a cylinder to be connected with a loading head seat board by a cylinder mounting plate; Between the pull bar upper end of cylinder boom and loading head, there are some clasps to be connected.
Compared with prior art, the utility model is real following apparent substantive distinguishing features and advantage: the loading procedure of stability test is more reliable and stable, and more vivid simulation the loading procedure of chair stool in the time that reality is used.Dwindled the overall dimensions of testing machine, shortened the stroke of cylinder, overall dimensions of the present utility model can be 1340 × 2260 × 2717mm, and cylinder stroke is 300mm, and being suitable for chair stool altitude range is 300 ~ 1200mm.
