Detailed description of the invention
As Fig. 1, lid device of the present utility model has the upper cover 21 being connected to anesthetic machine body, comprises lifting ring 24 and draw-in groove button 23 and cam drive 3 elevator unit and is arranged in the sealing ring 212 of lid 21 lower end.
As Fig. 2, elevator unit comprises lifting ring 24 and draw-in groove button 23 and cam drive 3, and lifting unit is arranged on lower house 22.Lower house 22 has a circular shrouding disc 221, the spacer ring 222 of annular is set with one heart at shrouding disc 221 upper side, and make the diameter of spacer ring 222 be less than the diameter of shrouding disc 221, form the annular side of shrouding disc 221 outside spacer ring 222, this annular side arranges two pilot holes 2211 be used for draw-in groove button motion guide, and these two pilot holes 2211 are by 180 ° of distributions.
Draw-in groove button 23 has Access Division 232 and is connected to the guide pillar 231 of upper end, Access Division 232, Access Division 232 is provided with the corresponding draw-in groove 2311 coordinated with the buckle 13 on the tank body 1 shown in Fig. 3, for the ease of quickly draw-in groove button 23 being fastened on the buckle 13 outside tank body 1, the well width of described groove is greater than the thickness of buckle 13, make between draw-in groove 2311 and buckle 13, to there is clearance t, as Fig. 4.As long as the tank body of correspondence be placed on the bottom corresponding to the lower house 22 of lid 2 like this and make buckle 13 corresponding with draw-in groove button 23 position on lid 2, then the buckle 13 draw-in groove button 23 on lid 2 being fastened to tank body is very nothing the matters.And the guide pillar 231 of draw-in groove button 23 is connected to through pilot hole 2211 lifting ring 24 lower end be socketed on outside spacer ring 222, lifting ring 24 rides on cam pack, like this, draw-in groove button 23 is by the combination with buckle 13, when drive tank body is to lid pressing under the pushing of cam pack, original relatively tank body position that lid is placed roughly will be made under the guiding of draw-in groove button to be corrected.
Two cam packs 32 form cam drive 3 with the rotating shaft 33 being connected this two cam pack 32.Rotating shaft 33 is rotating to be bearing on lower house 22.Place for the ease of rotating shaft 33, being provided with at spacer ring 222 1 diametric two positions place can straight line is through mutually groove 2221, groove 2221 is the groove of the U-shaped breach offered from spacer ring 222 upper side edge, can install rotating shaft 33 efficiently and easily like this, rotating shaft 33 is arranged in a diametrical position of lower house 22 through groove 2221 described in two.Through groove 2221 also can be set to corresponding through hole, considering, preferentially selecting the groove 2221 of described U-shaped breach from being convenient to setting angle.
As Fig. 5, for rotating conveniently, rotating shaft 33 one end is rotationally connected handle set 34, and the general manually operating grip seat 34 of rotation of rotating shaft 33 realizes.This handle set 34 pivot center is perpendicular to the axis of rotating shaft 33, make handle set 34 can do 90 ° folding, the basic center of handle set 34 is provided with a rectangular opening 341, this rectangular opening 341 serves as the handle (not shown) that cooperation one is provided with the suitable rectangle tenon with this rectangular opening, this handle is connected on handle set 34 by being inserted in the rectangular opening of handle set 34 by its rectangle tenon, like this can rotating shaft 33 more easily.
Rotating shaft 33 is rotated and makes cam pack 32 do the rotation of coaxial line, the lifting ring 24 relying on cam pack 32 does corresponding moving up and down with the change of cam pack 32 radius of gyration contacted with it, and 23, the draw-in groove button being connected to lifting ring 24 lower end does vertical moving up and down under pilot hole 2211 retrains.If draw-in groove button 23 moves upward, draw-in groove button 23 is by by pressing to tank body 1 on lid 2 with the combination of buckle 13.
Cam pack 32 can be an eccentric cam (not shown), is simple sliding frictions like this with the contact of the lifting ring 24 relied on it.As Fig. 6, one can reduce friction and anti-jamming preferred version be that cam pack 32 is the assembly comprising roller 321, roller support 322 and pivot pin 323, and roller 321 is rotationally connected on pivot pin 323, and pivot pin 323 two supports is on roller support 322.Such cam pack 32 carries out the contact of substantially rolling by a roller 321 and lifting ring 24, because rolling friction is much smaller than sliding friction, the cam pack structure shown in Fig. 6 except can reducing friction, also by the generation of the rolling minimizing stuck phenomenon of roller.
In order to make corresponding tank body and lid 2 pressing closely, a preferred scheme adopts resilient support assemblies 324, makes pivot pin 323 two supports of supporting rollern 321 in resilient support assemblies 324.As Fig. 7, corresponding to the roller support 322 of resilient support assemblies 324, with the roller support profile basic simlarity shown in Fig. 8, there is base 3221, this base be provided with two exist side by side place inverse-U-shape rack 3222, the spacing of two U-shaped supports is not less than the thickness of roller axis direction, to place roller 321 between two U-shaped supports.With roller support shown in Fig. 9 unlike, be provided with the incomplete locating surface for locating with pivot pin 323 in each inverse-U-shape rack inside top center: the first locating surface 32221, this first locating surface 32221 is the inner arc surface suitable with pivot pin 323.
Resilient support assemblies 324 is primarily of back-up block 3241, spring 3242 and locating dowel 3243 form, back-up block 3241 is basic cuboid, its upper end is provided with the second locating surface 32411 coordinated with described first locating surface 32221, this second locating surface 32411 is also the inner arc surface suitable with pivot pin 323, back-up block 3241 lower end is provided with protruding Cylindrical locating pins 32412, locating dowel 324 is connected on roller support 322 by close-fitting mode or screw joining manner, the lower end of spring 324 is socketed on locating dowel 3243, and make it locate on roller support 322, back-up block 3241 is plugged on the upper end of spring 3242 by alignment pin 32412, the elastic force of spring 3242 makes the second locating surface 32411 fit in the first locating surface 32221 and forms complete pivot pin 323 locating face, be a complete inner headed face, to carry out circumference constraint to pivot pin 323.The elastic force of spring 3242 also makes roller 321 position can resilient movement, pressure force between so corresponding tank body and lid 2 is a kind of pliable pressure, impact can not be formed, thus make imposed on pressure force can be larger, under larger pressure force effect, the sealing gasket of the two junction produces elastic deformation, can eliminate between tank body 1 and lid 2 and may there is gap.
In order to install cam pack 32 as shown in Figure 6,7 in rotating shaft 33, have employed and connect the cam pack 32 position setting joint face 331 parallel with axial plane in rotating shaft 33, the circle forming direction perpendicular to axial direction, joint face 331 place lacks shape cross section, as Fig. 8.Corresponding, roller support 322 lower end in cam pack 32 as shown in Figure 6,7, namely base 3221 lower end arranges and lacks the suitable through slot of shape cross section 32211 with the circle of rotating shaft 33, roller support 322 in rotating shaft 33, only needs a junction point between such roller support 322 and rotating shaft 33 by this through slot 3221 socket connection.For this reason, the joint face 331 of rotating shaft 33 arranges a screwed hole 3311, arrange unthreaded hole 32212 at the correspondence position of the base 3221 of roller support, screw is rotatably connected in screwed hole 3311 through unthreaded hole 32212, just roller support 322 very firmly can be connected in rotating shaft 33.This makes roller support 322 not only firm but also quick with the connection of rotating shaft.
