At present, be used in the supporting existing pallet of swivel chair, its governor motion is a handle when pulling up and down, by the roller roof pressure gasket compression stage clip that connects handle, regulates locking or loosen the brake sheet, and the chair back of swivel chair is swung within the specific limits.Chinese patent discloses a kind of pallet (Granted publication number: CN 2587252Y), it mainly comprises base plate, sliding seat, conical pipe and adjusting device, sliding seat is fixedly connected on base plate, opposite side in sliding seat is provided with a Taper Pipe fixed head, is fixedly connected between Taper Pipe fixed head and sliding seat and the conical pipe; Adjusting device includes adjusting rod, adjustable plate, torsion spring, torsion spring fixed head, and adjusting rod interts in sliding seat, and adjustable plate is fixedly connected on adjusting rod and inserts on the interior end of sliding seat, the one side contact air pressure rod of adjustable plate, and another side is connected with torsion spring; On the another side of adjustable plate, be provided with adjustable plate and end blade; With rivet sliding seat is riveted on the base plate, at the middle position of sliding seat welding conical pipe, all around the home on rivet, an end of torsion spring is fixed on the torsion spring fixed head, and a protruding bubble of adjustable plate is arranged on adjustable plate for torsion spring and torsion spring fixed head; Pallet is provided with a retaining mechanism, and retaining mechanism mainly comprises fixed block, rivet, adjusting rod, roller mount, roller, roller pin, regulating sleeve, rivet, adjusting bolt, stage clip, holder, brake(-holder) block, steel bushing, locking nut; Fixed block is fixedly connected on the sliding seat, its end activity penetrates rivet, one end activity of brake(-holder) block is fixed on the central authorities of rivet, the other end of brake(-holder) block is provided with the long waist shaped hole, in the hole, penetrate the adjusting bolt, an end of regulating bolt is screwed with locking nut, and is installed with steel bushing, and the steel bushing outer surface cooperates with a side of holder is movable, holder is fixedly connected on the base plate, the fixedly connected regulating sleeve in holder another side, at the inboard matched in clearance stage clip of holder, stage clip is wound on to be regulated on the bolt, regulate the end face roof pressure roller of bolt, roller is riveted on the roller mount with roller pin, and the side of roller mount penetrates rivet, flexibly connects with regulating sleeve; The inboard welding of other end adjusting rod in roller mount.But the retaining mechanism of this pallet is comparatively complicated, and the compression of stage clip is a transients, and it is when pressing also or loosening, and waving of the chair back is very rapid, brings great incompatibility for the first user or the person of being unfamiliar with.
The utility model content
The utility model technical issues that need to address provide a kind of multi-functional bidentate wheel swivel chair pallet, it mainly is that the compression of solution existing in prior technology pallet compression spring is a transients, it is when pressing also or loosening, waving of the chair back is very rapid, brings great unconformable problem for the first user or the person of being unfamiliar with; The utility model has also solved general pallet and has adopted brake(-holder) block locking, and brake(-holder) block and pad have the technical problem of mutual grating etc. when the chair back is swung.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Multi-functional bidentate wheel swivel chair pallet of the present utility model, comprise seesaw and housing, be provided with spring governor motion and retaining mechanism in the housing, the spring governor motion includes lifting handle, lifting handle is connected with first gear, first gears engaged has second gear, the coaxial connection bevel pinion of second gear, bevel pinion is by the spring assembly on the engagement bevel gear wheel connection swivel chair, it is characterized in that described retaining mechanism includes regulating handle, regulating handle by pull bar be connected with first the card mould, first the card mould by the single armed torsion spring be connected with second the card mould, second card is moulded and is connected with tooth bar, but enclosure interior is connected with the locking bed of locking rack.By the turn regulating handle, pull bar can spur first card and mould, and moulds with tooth bar by means of torsion drive card second card of single armed torsion spring to rotate again, and is locked together up to tooth bar and locking bed, thereby finishes the locking process.Tooth bar can integral body be trapezoidal, is convenient to lockmaking.
As preferably, described first card is moulded with second card and is moulded a side that all is connected tooth bar, and second card is moulded by connector and tooth bar and fixed.Second the card mould and can be fixed on the tooth bar with Philip's head screw, and then with the single armed torsion spring pack into first the card mould after, by torsion with first the card mould stick into second the card mould in,
As preferably, described first card is moulded to mould with second card and is had through hole, its coaxial being socketed on the fixed axis, and fixed axis is fixed on enclosure interior.First card can be moulded the through-hole alignment of moulding with second card during assembling, it is packed on the fixed axis of aluminum component in the housing, the free end of moulding at first card colludes into pull bar again.
As preferably, the number of teeth of described tooth bar is 2～10.The number of teeth of tooth bar can be 5, like this can be in the gradient of 5 gear adjusted chair back.
Therefore, the utlity model has and to prevent the automatic resilience of the chair back, when the chair back is swung, can eliminate friction, overcome the deficiency that existing pallet exists, make the user of pallet feel more comfortable, characteristics such as simple and reasonable for structure.
