It with Reusability, avoids dismantling, saves performance cost.
3, for extending table of the invention when being accommodated in main offstage, several pieces of stage boards are stored in lifting in stacked state
On platform, several brackets corresponding with stage boards are stored in nested fashion, reduce volume of the extending table in storage,
The occupancy to main offstage space is reduced, saves space for the other structures of modern main offstage.
4, stage board ends of the invention are provided with inclined surface, and thus structure, may be implemented, adjacent stage boards by
It can become overlaying state when extruding force along inclined surface upward sliding, can slide in and out become along inclined surface when subjected to tension
Tiled state, the expansion for making stage boards and storage operation make the deformation side of aggregation type stage by simply pushing away, pulling and realize
Formula becomes simple.
5, stage boards side of the invention is provided with ground way and mobile slideway, passes through two between adjacent stage boards
Connecting rod is slidably connected in two slideways, and thus structure, may be implemented, and stage boards are in opposite sliding process, for connecting
Connecting rod slided in ground way or mobile slideway, limit the sliding position and distance of adjacent stage boards, make adjacent stage
The relative motion angle of plate is 90 degree, i.e., from parallel sliding to stacking, and in sliding process, adjacent stage boards are remained
Contact, sliding stability, meanwhile, under tiled state, two connecting rods are in contact, and are in the junction of two stage boards, limit
Stage boards processed continue to slide, and guarantee the coincidence of two plate faces, and under stacked state, two connecting rods are in the two of stage boards
Side guarantees the stability of the stage boards of stacked state.
6, lifting platform of the invention includes lifting table plate, pulley combination clump weight, and lifting table plate is for holding stacked state
Stage boards, lifting table plate is connected with clump weight by pulley blocks, so that lifting table plate is risen offer stage boards automatically, or from
Dynamic decline storage stage boards.
7, the clump weight of lifting platform of the invention includes a main clump weight and several secondary clump weights, if main clump weight and
Dry secondary clump weight is successively fixed on the rope with constant spacing interval, and thus structure, may be implemented, and lifting platform is sliding
During, clump weight can change the pulling force that lifting platform applies with lifting platform sliding distance, and lifting platform sliding away from
It from corresponding with the stage boards quantity on lifting platform, may be implemented, stage boards are adjusted according to the stage boards quantity of stacked state, dynamic
The size of support force, the pressure that stage boards are subject at the top of reduction in the case where guaranteeing the support to stage boards, and then reduce phase
The resistance that adjacent stage boards are subject to when sliding into stacked state from tiling reduces resistance of extending table during storage.
