Utility model content
The utility model is to provide a kind of Revolving chair tray torsion spring forward type mechanism, its torsion spring mechanism mainly solving the Revolving chair tray existing for prior art can occupy larger space in Revolving chair tray, make the overall dimensions of Revolving chair tray larger, structure is comparatively complicated, the technical problem that production cost is more high.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Revolving chair tray torsion spring forward type mechanism of the present utility model, comprise middle base assembly, described middle base assembly is fixed with left plate, right plate, between left plate and right plate, cross-under has rotatable and flexible adjusting rod, adjusting rod part between left plate and right plate is provided with kink, adjusting rod one end is stretched out outside middle base assembly, between middle base assembly, left plate, right plate, cross-under has rivet, rivet is socketed with torsion spring lining, the two ends of torsion spring lining are respectively equipped with left torsion spring, right torsion spring, and left torsion spring, right torsion spring are located at the front end of transfer tray.Base assembly is stressed rotate along rivet time, left torsion spring, right torsion spring pressurized play a role, and when cancelling the power of base assembly, torsion spring loosens, base assembly homing.After two torsion springs are preposition, structure is comparatively simplified, and compared to the torsion spring mechanism being arranged on middle part, Revolving chair tray profile can be made less.
As preferably, the top of described middle base assembly rear end is provided with silencer pad.Can reduce by silencer pad the noise that bottom deck assembly produces when swinging up and down, and safeguard that transfer tray can not be worn.
As preferably, described left plate, right plate are provided with mounting hole, are provided with stop screw between mounting hole and middle base assembly.Stop screw can move in the mounting hole of left plate, right plate, thus the amplitude that restriction left plate, right plate swing.
As preferably, described adjusting rod end is connected with handle, handle and adjusting rod is orthogonal sets up.Utilize handle, rotate and pull adjusting rod all comparatively easy.
As preferably, between described left plate, the rear and front end of right plate, be fixed with front web beam, rear web beam respectively.Front web beam, rear web beam can strengthen the intensity of whole Revolving chair tray, and adjusting rod operationally not easily rocks.
Therefore, torsion spring is divided into left torsion spring, right torsion spring by the utility model, and is placed on the front end of Revolving chair tray, can streamline organizations like this, and be that Revolving chair tray profile is more smart little, cost is more saved, simple and reasonable for structure.
