Detailed description of the invention
Presently in connection with drawings and Examples, the present invention is further detailed explanation, and these accompanying drawings are the schematic diagram of simplification, and the basic structure of the present invention is only described in a schematic way, and therefore it only shows the composition relevant with the present invention.
As depicted in figs. 1 and 2, a kind of novel experiment lifting platform, including experiment table top 10 and the base 20 supporting experiment table top 10, two parallel scissors mechanisms are slidably connected between experiment table top 10 and base 20, two scissors mechanisms are provided with the adjustment device driving scissors mechanism flexible, scissors mechanism is made to stretch by regulating device, so that experiment table top 10 lifts；Experiment table top 10 is equipped with the placement table 11 that can stretch out experiment table top 10, two scissors mechanisms are connected to and order about the actuator that placement table 11 stretches out, the process that scissors mechanism is flexible drives actuator effect, thus actuator makes placement table 11 stretch out or experiment table top 10 of retracting；Being also associated with cushioning and supporting device between base 20 and experiment table top 10, experiment table top 10, in the process declined, makes experiment table top 10 slowly decline by buffer unit, it is to avoid under experiment table top 10 falls suddenly.
Concrete, scissors mechanism is the hinged frame 30 of X-shaped, being connected to two crossbeams 31 between the end of wherein one end of two hinged frames, the adjustment device in the present invention includes end and has the screw rod 42 regulating handle 41, and screw rod 42 runs through two crossbeams 31 and threadeds with one of them crossbeam 31.When utilizing adjustment handle 41 rotary screw 42, the crossbeam 31 threadeded with screw rod 42, along screw rod 42 transverse shifting, stretches thus ordering about hinged frame 30, and hinged frame 30 drives experiment table top 10 to lift.
Further, connect between two hinged frames 30 and drive axle 32, the two ends driving axle 32 are connected to the hinged place on two hinged frames 30, and the actuator in the present invention is that one end is connected to two connecting rods driven on axle 32, and the other end of two connecting rods is connected on placement table 11 medial surface.Driving while hinged frame 30 is flexible drives axle 32 to lift, and drives axle 32 to drive connecting rod effect, thus connecting rod drives placement table 11 to stretch out or experiment table top 10 of retracting.
Being equipped with the connector with chute 70 on experiment table top 10 in the present invention and base 20, connector is respectively arranged on the first connector 71 on experiment table top 10, and be arranged on base 20 with the first connector 71 the second connector 72 in opposite directions；And hinged frame 30 includes the first hinge bar 33 and the second hinge bar 34 that middle part is hinged, one end of first hinge bar 33 is slidably connected in the chute 70 of the first connector 71, one end of second hinge bar 34 is fixed on the end of the first connector 71, being slidably connected in the chute 70 of the second connector 72 by the other end of the second hinge bar 34, the other end of the first hinge bar 33 is fixed on the end of the second connector 72.When utilizing adjustment handle 41 rotary screw 42, one of them crossbeam 31 is along screw rod 42 transverse shifting, this moveable crossbeam 31 connects two second hinge bars 34 and is slidably connected at the both ends in chute 70, the crossbeam 31 of transverse shifting drives the second hinge bar 34 to slide along chute 70, again because the first hinge bar 33 and the second hinge bar 34 are hinged, second hinge bar 34 orders about the end of the first hinge bar 33 chute 70 along the first connector 71 and slides while sliding, thus realizing the flexible of hinged frame 30.
Concrete, connecting rod in the present invention includes the first connecting rod 51 and the second connecting rod 52 that are hinged, is rotatably connected to rotating shaft 53 in the hinged place of first connecting rod 51 with second connecting rod 52, is slidably connected with the chute 70 on the first connector 71 one end of rotating shaft 53.Hinged frame 30 is in telescopic process, drive axle 32 also with lifting, it is connected to and drives the connecting rod on axle 32 also with lifting, concrete, rotating shaft 53 is slided along chute 70, orders about first connecting rod 51 and second connecting rod 52 stretches, and placement table 11 1 aspect lifts with experiment table top 10, on the other hand under the effect of connecting rod, extended or retracted experiment table top 10.
Cushioning and supporting device in the present invention includes the first sleeve 61 being connected with base 20 and the second sleeve pipe 62 being connected with experiment table top 10 being socketed in first sleeve 61, and the one end being inserted within first sleeve 61 at the second sleeve pipe 62 is connected back-moving spring 63 with the bottom of first sleeve 61.Experiment table top 10 is in decline process, and experiment table top 10 is under the effect of self gravitation, and decrease speed can be very fast, and now, experiment 10 1 resiliency supported of table top given by back-moving spring 63, make experiment table top 10 slowly decline, it is to avoid suddenly under pendant.
The experiment lifting platform of the present invention provides the benefit that:
1, by setting placement table on experiment table top, in the process of manual adjustments experiment table top lifting, ordering about placement table and stretch out or retracts experiment table top, when operation experiments, placement table can be used to individually placed experimental article, does not affect and is testing operation experiments on table top；
2, pass through to arrange buffer unit between experiment table top and base, it is to avoid under experiment table top falls suddenly in the process declined, it is ensured that use safety；
3, regulate the simple in construction that experiment table top lifting is flexible with ordering about placement table, easily operate.
Above according to the desirable embodiment of the present invention for enlightening, by above-mentioned description, related personnel in the scope not necessarily departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content in description, it is necessary to determine technical scope according to right.
