Specific embodiment

It is illustrated below in conjunction with preferred embodiment of the attached drawing to the utility model, it should be understood that described herein excellent It selects embodiment to be only used for describing and explaining the present invention, is not used to limit the utility model.

Embodiment: as shown in Figure 1-3, the utility model provides a kind of technical solution, attendant seat's spring assembling/disassembling tool, Including baffle 1,1 side of baffle offers circular hole 2, and 1 one end of baffle is bonded with limit plate 3, in order to prevent limit plate 3 and baffle 1 Between fall off, in turn resulting in baffle 1 can not fix, between limit plate 3 and baffle 1 by be welded to connect, 3 top two sides of limit plate Screw hole 4 is offered, for the ease of the placement of screw rod, prevents screw head in the external world, so that personnel sit on the seat not Comfortable phenomenon, 4 top of screw hole offer placing groove, and 3 bottom end of limit plate is equipped with stripper plate 5, in order to prevent 3 He of limit plate It falls off between stripper plate 5, so that the phenomenon that baffle 1 is unstable, is connected between limit plate 3 and stripper plate 5 by flexible gluing knot It connects, 1 bottom of baffle offers spring groove 6, and 1 top middle portion of baffle opens up fluted 7, and 7 side of groove offers limiting slot 8, limit Position 8 edge of slot is equipped with bottom plate 10, and 10 top side of bottom plate is equipped with convex block 9, for the ease of being put into for convex block 9, so that Bottom plate 10 is fixed, further such that cylinder 11 is fixed, the outer diameter of convex block 9 is less than the internal diameter of limiting slot 8,10 other side of bottom plate middle part Cylinder 11 is installed, the phenomenon that cylinder 11 gets rusty because water stain in order to prevent, cylinder 11 is further prevented to generate corruption because water stain The phenomenon that erosion, 11 outer application of cylinder have antirust paint, and 11 inner wall of cylinder is equipped with piston 16, and 16 bottom end of piston is equipped with piston rod 17, gas-charged pressure chamber 18 is offered on the outside of piston rod 17, and 18 bottom part down of gas-charged pressure chamber offers oil pocket 19,19 bottom of oil pocket Lower section offers sealed chamber 20.

1 other side of baffle is equipped with dust excluding plate 13, for the ease of the rotation of dust excluding plate 13, further prevents spring Shield, is connected by a hinge, dust is bonded in 13 surface of dust excluding plate in order to prevent, makes dust excluding plate 13 between dust excluding plate 13 and baffle 1 The dust on surface is difficult to clean, and then keeps 13 surface of dust excluding plate unclean, and 13 top of dust excluding plate is bonded with protective film, dust excluding plate 13 Middle part offers U-lag 14, in order to keep U-lag 14 and ring spring fixation more steady, prevents extraneous moisture and water stain touches bullet Spring, 14 two sides of U-lag are covered with sponge, and 6 two sides of spring groove offer fixation hole 15.

The working principle and process for using of the utility model: attendant seat's spring assembling/disassembling tool in actual use, In the case where stretching seat spring, so that spring force is reached maximum, rotate dust excluding plate 13, so that U-lag 14 is detached from spring head, into And spring side is dismantled convenient for personnel, spring reaches because elastic force is collapsible into inside spring groove 6 and overcomes seat spring elastic force Purpose, then the bottom plate 10 inside turning groove 7, is inserted into the convex block 9 of 10 bottom of bottom plate in limiting slot 8, passes through limit Bottom plate 10 is fixed in slot 8 and convex block 9, pulls piston rod 17, so that piston 16 moves inside cylinder 11, closed inflation Inert gas is filled in pressure chamber 18, and perhaps gas mixture makes the intracorporal pressure of chamber higher than several times or tens of atmospheric pressure Times, it is less than the cross-sectional area of piston 16 in the cross-sectional area using piston rod 17, thus the pressure difference generated, Lai Shixian piston 17 Movement, the top plate 12 at the top of piston rod 17 is fixed on backrest, and then reduces required work people when disassembly spring Member, and then the withdrawal space is increased, to be convenient for staff to dismantle spring, staff is improved to attendant seat The speed of spring dismounting and the efficiency of dismounting, consolidating to piston rod 17 is realized by the air pressure of oil pocket 19 and sealed chamber 20 It is fixed, prevent piston rod 17 from the phenomenon that inwardly squeezing occur because of the elastic force of spring, and then unscrew in screw hole 4 and fixation hole 15 The fixture nut in portion, so that limit plate 3, baffle 1 and stripper plate 5 take from spring surface, further convenient for receipts The spring of contracting is dismantled.

Finally, it should be noted that being not limited to this reality the foregoing is merely the preferred embodiment of the utility model With novel, although the utility model is described in detail with reference to the foregoing embodiments, come for those skilled in the art Say, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic into Row equivalent replacement.Within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on, should all It is included within the scope of protection of this utility model.
