The specific embodiment

Referring to Fig. 1 and Fig. 2, this embodiment is provided with platen 2 in the upper end of described framework 12, and at the downside connection longitudinally guiding body of this platen 2, this longitudinally guiding body is the guide rod 11 that is connected four bights of platen 2 downsides, and the slideway corresponding with it is slide opening 19.The lifting drive of this embodiment comprises L shaped elevating lever 10, motor 9, active umbrella point wheel 7, driven umbrella point wheel 8, screw rod 5, nut 6, and the top of elevating lever 10 is connected with the outside of nut 6 with vertical connection of platen 2 downsides, its lower end.Screw rod 5 vertical rotating supports are between the top and bottom of framework 12, and nut 6 is threaded onto on this screw rod 5, and driven bevel pinion 8 is connected the bottom of screw rod 5, and driving bevel gear 7 is connected with the axle of motor 9 on being loaded in the frame, and driving and driven umbrella is taken turns and is meshing with each other.In described framework 12 upper ends two fan clamshell doors 1 are arranged, its size is slightly larger than the size of described platen 2, so that platen 2 can be passed through.Be connected with mechanism for opening/closing (as shown in Figure 2) in clamshell doors 1, this mechanism for opening/closing comprises and opens and closes gear 13, two semi-circle gears 4 and two connecting rods 3, opening and closing gear 13 is connected on the lower, transverse part of described L shaped elevating lever 10, its both sides semi-circle gear 4 relative with two tooth tops is meshed, each is connected the outside of two semi-circle gears 4 with an end of a connecting rod 3, and the outward flange (promptly with framework hinge one side) that the other end of this connecting rod and described two is fanned clamshell doors 1 is connected.

Referring to Fig. 3, this embodiment has lacked mechanism for opening/closing than a last embodiment, and other structure is identical.Two fan clamshell doors 1 are pushed open when being placed on article 14 risings on the platen 2.

Referring to Fig. 4, this embodiment has removed the fan of two in the foregoing description clamshell doors 1, also is provided with framework panel 15 and dividing plate 16 above the described platen 2, and framework panel 15 is positioned at the superiors, dividing plate 16 connects by vertical pillar between the three between platen 2 and framework panel 15.

Referring to Fig. 5 and Fig. 6, the guide way of this embodiment is a plate body 18, and the upper end of this plate body 18 is connected with described platen 2, and this plate body 18 has vertical slide opening to insert the slide bar 11 that is connected with described framework; Described lifting drive comprises motor 9, driving bevel gear 7, driven bevel pinion 8, screw rod 5, nut 6, screw rod 5 vertical rotating supports are between the top and bottom of framework 12, nut 6 is threaded onto on this screw rod 5, the outside of nut 6 is connected with described plate body 18, driven bevel pinion 8 is connected the bottom of screw rod 5, the axle of the motor 9 that driving bevel gear 7 is interior with being loaded on framework is connected, and driving and driven umbrella wheel is meshing with each other.

Fig. 7 shows a kind of lifting control circuit of the present invention, described control circuit comprises and rises K switch 1 and fall K switch 2 and described upper and lower stop travel switch XK1 and XK2, K1 and K2 are two the interconnected switches in the switch, K1 and XK1 are connected on just going back in the road of described motor 9, and K2 and XK2 are connected in the counter-rotating loop of described motor 9.S1 among the figure, S2 represent lifting power supply (actual is a power supply, at this for operation principle is described) respectively, and K1, K2 are respectively direction switches.After opening K1, platen 2 is driven by nut 6 and moves up, and touches XK1 when arriving top dead centre, makes its disconnection, and rising stops.When needs are fallen platen 2, open K2 (K1 closes simultaneously), platen 2 begins to descend, and touches XK2 when arriving lower dead center, makes its disconnection, and motor 9 quits work.
