The utility model content
The utility model provides a kind of seat pallet with the transverse type stage clip, it mainly is to solve the existing pallet of prior art to regulate inconvenient for the degree of tightness of seat, the shared spatial volume of pallet is larger, and in use, the people must leave the technical problem that the seat could carry out to Revolving chair tray degree of tightness adjusting etc.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of seat pallet with the transverse type stage clip of the present utility model, comprise tray main body, cross-under has pressure adjusting screw on the described tray main body, but pressure adjusting screw the inner is connected with the long bolt of move left and right by governor motion, be connected with left press spring base, right press spring base on the long bolt, left and right press spring base is laterally arranged, and left press spring base is connected with the stage clip pressing plate, right press spring base one side is provided with locking nut, is provided with stage clip between the left and right press spring base.After pressure adjusting screw rotates, can make the long bolt move left and right by governor motion, after the long bolt move left and right, can spacing between left press spring base, the right press spring base, regulate thereby finish the stage clip degree of tightness, can reach the degree of tightness of adjusting seat.Whole like this pallet spatially than originally more narrow and small, is convenient to packed and transported
As preferably, described governor motion includes the external pressure regulating block that pressure adjusting screw the inner is connected with, the external pressure regulating block is provided with the inclined-plane, the external pressure regulating block slidely connects leg-of-mutton internal pressure regulating block by the inclined-plane, the internal pressure regulating block is fixed on the long bolt, and the another side of internal pressure regulating block is provided with pressure and regulates fixed block.Pressure adjusting screw can promote the external pressure regulating block and move after rotating, and drives simultaneously internal pressure regulating block move left and right by the inclined-plane, orders about at last the long bolt move left and right.
As preferably, be provided with square nut between described pressure adjusting screw and the tray main body.Can play spacing effect to pressure adjusting screw.
As preferably, the outer end of described pressure adjusting screw is connected with pressure regulating handle.Pallet is regulated more conveniently like this, need not turn chair around adjusting, as long as the people is sitting on the chair, rotates and regulates the tightness that pressure regulating handle 7 just can adjusting seat, makes the people can be adjusted at short notice the state that is fit to self, makes the people more comfortable.
