The specific embodiment
Below in conjunction with embodiment the utility model is further described.
As depicted in figs. 1 and 2, at the bottom of this whole height, the chassis of the compressed spring type spring traverse of being convenient to transport, there are four holes to be used for connecting the seat support of swivel chair at four angles of base plate 1, be connected on the sliding seat 24 with long rivet 20 in the middle of base plate 1, mounting bush 25 between long rivet 20 and the sliding seat 24 is at the middle position welding Taper Pipe 22 and the door sections 23 of sliding seat 24, Taper Pipe 22 is enclosed within the head of air pressure rod, and fixed support plays whole chassis.Adjusting rod 21 penetrates sliding seat 24, and be positioned at adjusting rod 21 sliding seat 24 inboards Taper Pipe 22 above, carry out a bending, and make the bending outermost end be positioned at the center, top of Taper Pipe 22, withstand air pressure rod, and the rotational angle of control and regulation bar 21 and prevent that adjusting rod from pulling out, the other end of adjusting rod 21 has the bending of a L type, and the outermost end of L type is installed handle 19; Pull handle 19, adjusting rod 21 is that supporting-point rotates with two circular holes of sliding seat 24, and the head that compresses air pressure rod moves up and down, and air pressure rod is risen or decline, thereby drives the lifting of chair.Establish two holes at the front end of sliding seat 24, a short rivet 14 is movably riveted on spring base 7 on the sliding seat 24, spring base 7 is offered a hole away from the center of the outermost face of sliding seat 24; At the front end of base plate 1, weld a supporting seat 2, supporting seat 2 is also offered a circular hole corresponding to the position of the outer end circular hole of spring base 7; Make an adjusting screw(rod) 4, pass minipad 16, bowl-type pad 15, stage clip 5 and plastic seat 6, pass the outer end circular hole of spring base 7, pass the circular hole on the supporting seat 2 that is weldingly fixed on the base plate 1 again, pass minipad 8 and bearing 9, tighten adjusting screw(rod) 4 with hex nut 10; Make stage clip 5 and base plate 1 approaching parallel placement.When base plate 1 time around 20 swings of long rivet, be welded on the supporting seat 2 outside top minipads 8 on the base plate 1, minipad 8 outside apical axis hold 9, bearing 9 outside top hex nuts 10, and 10 drives of hex nut adjusting screw(rod) 4 is outwards mobile; The other end of adjusting screw(rod) 4, tightly pressing minipad 16, minipad 16 is tightly pressing bowl-type pad 15, bowl-type pad 15 tightly pressing stage clip 5, and stage clip 5 is tightly being pressed plastic seat 6, and plastic seat 6 is tightly being pressed spring base 7, and spring base 7 is movably riveted on the sliding seat 24, can not outwards move, so moving of screw rod caused compression to stage clip 5, the mass motion of mechanism has produced elastic force.The outside of hex nut 10, put the worm gear 11 that cooperates the hex nut profile is arranged in one, end at supporting seat 2, be provided with two holes, a rotation handwheel 18 is penetrated in supporting seat 2 hole on one side, pass worm screw 3, pass from another hole of supporting seat 2, and make worm screw 3 be close to 11 one-tenth engagements of worm gear, with a jump ring 17, to rotate handwheel 18 in the inboard of supporting seat 2 fixing, it can not be drawn out, in the rotation handwheel 18 that rotates at the chassis side, then drive worm screw 3 and rotate, worm screw 3 drives worm gear 11 and rotates, worm gear 11 drives inner hex nut 10 and rotates, and by the rotation of hex nut 10 fixed positions, adjusting screw(rod) 4 is moved, change the size of stage clip 5 decrements, form adjusting mechanism's elastic force size.And on supporting seat 2; with two sunk screws 12 plastics over cap 13 is fixed on the supporting seat 2, and covers inner parts such as stage clip 5, guarantee that mechanism is in operation; can be to user or children's finger, cause and crush owing to putting into mechanism because of carelessness.
At last, should be pointed out that above example only is the more representational example of the utility model, obviously, the utility model is not limited to the foregoing description, and many distortion can also be arranged.Every foundation technical spirit of the present utility model is to any simple modification that above embodiment made, and equivalent variations and decoration all should be thought to belong to protection domain of the present utility model.
