Fig. 2 is a reverse side perspective view of the present utility model;

The specific embodiment:

Below in conjunction with embodiment the utility model is further described.

As shown in Figure 1 and Figure 2, this pallet, mainly comprise base plate 1, sliding seat 2, conical pipe 10 and adjusting device, sliding seat 2 is fixedly connected on base plate 1, and 2 holes are arranged in the both sides of sliding seat, adjusting rod 4 is penetrated, this adjusting rod 4 is important composition parts in the adjusting device, and adjusting device has adjusting rod 4, adjustable plate 5, torsion spring 6, torsion spring fixed head 7.Adjusting rod 4 interts in sliding seat 2, can be movable in sliding seat 2, adjustable plate 5 is welded on adjusting rod 4 and inserts on the interior end of sliding seat, the one side contact air pressure rod of adjustable plate 5, can regulate the lifting of swivel chair, the another side of adjustable plate is subjected to the pressure of torsion spring 6, make adjustable plate 5 top-pressure gas pneumatic rod all the time, when swivel chair can not send chatter during in swing.

8 mounting holes are arranged on the base plate 1, be connected and fixed seat support by bolt.With rivet 8 sliding seat 2 is riveted on the base plate 1, at the middle position welding conical pipe 10 of sliding seat 2, conical pipe 10 connects air pressure rod, the whole pallet of fixed support.Drawing and forming around sliding seat 2 is carried out improves intensity, overcome with preceding because of insufficient strength, and can not be by the defective of test.

For making conical pipe 10 connect sliding seat 2 more firmly, added a Taper Pipe fixed head 11 at the opposite side of sliding seat 2, weld between Taper Pipe fixed head 11 and sliding seat 2 and the conical pipe 10.

All around the home on rivet 8, an end of torsion spring is fixed on the torsion spring fixed head 7 for torsion spring 6 and torsion spring fixed head 7.On the another side of adjustable plate 5, have adjustable plate to end blade 3, when making adjustable plate forward certain angle to and sliding seat collide, can not make torsion spring surpass its extreme angles.When an end of adjusting rod 4 inserts in the base plate, can pin wholely the swing of swivel chair, because of a protruding bubble 9 of adjustable plate is arranged on adjustable plate 5, it is hindered by torsion spring 6, can not come out easily when making adjusting rod 4 penetrate bottom plate hole; When filling in bottom plate hole, adjusting rod 4 can not penetrate easily.

For seat in when layback, can live in arbitrary positional lock, ad hoc meter one cover locking mechanism, be attached on the base plate, described retaining mechanism by: fixed block 12, rivet 13, adjusting rod 14, roller mount 15, roller 16, roller pin 17, regulating sleeve 18, rivet 19, regulate bolt 20, stage clip 21, holder 22, brake(-holder) block 23, steel bushing 24, locking nut 25 and form.Fixed block 12 is welded on the sliding seat 2, its end activity penetrates rivet 13, one end activity of brake(-holder) block 22 is fixed on the central authorities of rivet 13, the other end of brake(-holder) block 23 has the long waist shaped hole, in the hole, penetrate and regulate bolt 20, an end of regulating bolt 20 is screwed with locking nut 25, and be installed with steel bushing 24, steel bushing 24 outer surfaces cooperate with a side of holder 22 is movable, and holder 22 is welded on the base plate 1, holder 22 another sides welding regulating sleeve 18, inboard matched in clearance stage clip 21 at holder 22, stage clip 21 is wound on to be regulated on the bolt 20, regulates the end face roof pressure roller 16 of bolt 20, on roller 16 usefulness roller pins, 17 riveted joints and the roller mount 15, the side of roller mount 15 penetrates rivet 19, flexibly connect with regulating sleeve 18, being built into rivet 19 like this is rotating shaft, is the eccentric wheel of salient point with roller 16.The inboard welding of other end adjusting rod 14 in roller mount 15, only need pull adjusting rod 14, just can allow roller mount 15 rotate, compression (loosening) stage clip around rivet 19, force to regulate in the bolt 20 and move (moving) outward, make the brake(-holder) block 23 mutual gaps that are superimposed upon on the adjusting bolt 20 strengthen (reducing).When the gap of brake(-holder) block 23 was strengthened, the seat support of swivel chair can rotate around rivet 8 under the effect of external force, when the gap of brake(-holder) block 23 reduces, has increased the mutual friction of brake(-holder) block, just can be locked in a fixing position to the seat support of swivel chair.And adjusting rod 14 can be because of the swing of the swivel chair chair back, and changes its height, again because of adjusting rod 14, be installed on the regulating sleeve 18 on the holder 22 that is welded on the base plate 1, very near from seat support, hand is as long as one get rid of a little, with regard to stretchy adjusting rod 14, the people can not feel very hard when the locking seat support.
