Utility model content
The utility model is to provide a kind of easy locking line traffic control seat tray, it is mainly to solve comparatively complexity of the existing Chair underframe structure of prior art, production cost is higher, and is that employing rod member is locked, lift adjustment, the technical problem of the comparatively numerous and diverse grade of operation.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of easy locking line traffic control seat tray of the present utility model, comprise base, base is connected with bearing pin with sliding seat, in described sliding seat, be provided with rotatable gear regulating block, gear regulating block is connected with shift control bracing wire, gear regulating block is connected with gear and regulates torsion spring, and gear regulates the other end of torsion spring to be provided with the check lock lever in the through hole that can penetrate base, is also provided with lowering or hoisting gear in sliding seat.Pull after shift control bracing wire, gear regulating block can rotate, thereby drives gear to regulate torsion spring rotation, and check lock lever just can move up and down.When check lock lever moves upward, it can penetrate in the through hole of base one side, thereby makes whole seat tray in locking state; When check lock lever moves downward, check lock lever can leave through hole, and now whole pallet is in non-locking state.
As preferably, described lowering or hoisting gear includes the lift adjustment piece in base, and lift adjustment piece is located on elevating control seat, and the cross-under of lift adjustment piece has alignment pin, and lift adjustment piece is connected with elevating control bracing wire.Pull after elevating control bracing wire, lift adjustment piece can be rotated down motion around alignment pin; Unclamp after elevating control bracing wire, lift adjustment piece can rotate up reset around alignment pin, thereby realizes Revolving chair tray elevating function.
As preferably, described gear regulating block is connected with little torsion spring, and the little torsion spring other end is fixed in elevating control seat.Little torsion spring can make gear regulating block reset.
As preferably, described gear regulates one end of torsion spring to be connected in the long lumbar hole of gear regulating block, and the other end is connected on limited block, and limited block is connected on check lock lever.
As preferably, described elevating control seat is provided with two ears and climbs, and ear is climbed up and had aperture.Aperture and lift adjustment piece that alignment pin is climbed up through ear, be fixed on elevating control seat lift adjustment piece.
Therefore, the utility model is controlled respectively locking and the elevating function of pallet by shift control bracing wire, elevating control bracing wire, operates comparatively simply, and production cost is lower, simple and reasonable for structure.
