This unit synchronization lifting, meets the use under special state.As can be seen here, this utility model autgmentability is strong, it is possible to achieve many
Use under scape.
This utility model is further optimized for as shown in fig. 6, two basic support member A1 connection composition elementary cells A2, and two
Individual elementary cell A2 superposition composition hoistable platform, the second support member of top elementary cell and the first support of lower section elementary cell
It is threaded connection between part, makes the impulse stroke of hoistable platform bigger, and the lifting of elementary cell can be adjusted respectively, realizes
Precise controlling adjustable height；Assemble to be formed by rhombus component, production cost is lower.
This utility model is further optimized for as shown in fig. 7, rhombus includes that two or more are hinged in basic support member A1
Rhombus, be respectively equipped with the first support member and that rhombus component is connected at the first drift angle 1 of rhombus component, the 3rd drift angle 3
Two support members, are respectively equipped with the first movement parts and the second movement parts for connecting rhombus component at the second drift angle 2, the 4th drift angle 4,
Wherein the first movement parts are provided with the first screwed hole, and the second movement parts are provided with the second screwed hole, the first screwed hole and the second screwed hole
The hand of spiral conversely, screw mandrel passes through the first screwed hole and the second screwed hole, screw mandrel to be provided with and the first screwed hole, the second screw thread
The threaded portion that hole coordinates.So using the rhombus component of multiple rhombuses composition, further increase the impulse stroke of hoistable platform, and
The lifting of hoistable platform is controlled using a screw mandrel, work efficiency is improved.
This utility model be further optimized for as shown in figure 8, in basic support member A1 the connecting rod of rhombus component extend to
First support member, the second support member horizontal level it is identical, so can form lifting merely with a basic support member A1 flat
Platform；Connecting rod end arranges hinge hole 9, rhombus component is hinged with other rhombus components, is constituted using multiple rhombus components
Hoistable platform, to increase bearing capacity or loaded area.
In above-described embodiment, as shown in figure 9, handle 7 includes the connecting portion 71 being connected with screw mandrel 5, the end of connecting portion 71
