Description
Technical field
The utility model relates to a kind of teaching equipment, is specially a kind of teaching dais.
Background technology
In teaching process, during some course teaching, need on blackboard, write a large amount of content, and consider that student's reason of recording the note can not clash content on blackboard immediately, blackboard corner parts will be used like this, but because height reason, quite hard during lecturer's writing blackboard headroom, difficult especially for short lecturer.
Utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of teaching dais, its structure is simple, facilitate lecturer to write say teaching, improve the usable floor area of blackboard.
The utility model solves technical scheme that its technical problem adopts: a kind of teaching dais, comprise platform and lectern, described lectern is arranged in the central front position of described platform near described platform, it is characterized in that: described platform comprises base plate, described base plate is arranged with some elevators, described elevator comprises top board and is arranged on described base plate for supporting described top board and the hydraulically extensible device supporting described top board to be elevated, described hydraulically extensible device is driven by Hydraulic Station, top board is provided with the switch of hydraulic control expansion bend, corner is respectively equipped with spring base in described top board bottom surface, on described base plate, correspondence is provided with spring base, connected by spring between described spring base.
Further, described spring is Compress Spring.
Further, described switch and the total lock be arranged on described lectern electricly connect.
Further, described cover top surface is provided with anti-skidding lines.
Further, closely arrange between adjacent described top board.
Further, the lower end of described hydraulically extensible device is fixed on base plate, and the soffit of described top board is fixed with support member, and described support member is fixedly connected with described hydraulically extensible device upper end.
Further, described support member comprises cross reinforcing rib.
The beneficial effects of the utility model are: teaching dais of the present utility model, by the cooperation of hydraulically extensible device, top board etc., when blackboard writing on the blackboard content is more, lecturer needs to utilize the space writing on the blackboard at blackboard top or teaching to say class hour, may stand on top board, by the switch of hydraulic control expansion bend, hydraulically extensible device is stretched out, drive top board moves upward, closing switch behind in-position; When needs decline, also can pass through switch control rule hydraulically extensible device, make it to shrink, drive top board to move downward, get back to closing switch after original position, have structure simple, easy to use, facilitate lecturer to say the feature of teaching.
Accompanying drawing explanation
Fig. 1 is the structural representation at teaching dais of the present utility model;
Fig. 2 is the structural representation of the upper surface of the top board at teaching dais of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model will be further described, but protection domain of the present utility model is not limited to the following stated.
As Fig. 1, shown in Fig. 2, one teaching dais of the present utility model, comprise platform and lectern 6, lectern 6 is arranged in the central front position of platform near platform, platform comprises base plate 2, base plate 2 is arranged with some elevators, elevator comprises top board 2 and arranges on a base plate 2 for roof supporting 1 and the hydraulically extensible device 3 supporting top board 1 to be elevated, hydraulically extensible device 3 is driven by Hydraulic Station (not providing in figure), top board 2 is provided with the switch 5 of hydraulic control expansion bend 3, corner is respectively equipped with spring base 8 in top board 1 bottom surface, on base plate 2, correspondence is provided with spring base 8, connected by spring 4 between spring base 8, spring is Compress Spring, switch 5 and the total lock (not providing in figure) be arranged on lectern 6 electricly connect, top board 1 upper surface is provided with anti-skidding lines 7, closely arrange between adjacent top board 1, the lower end of hydraulically extensible device 3 is fixing on a base plate 2, the soffit of top board 1 is fixed with support member 9, support member 9 is fixedly connected with hydraulically extensible device 3 upper end, support member 9 comprises cross reinforcing rib 10.
Four bights of top board 1 bottom surface are provided with the spring 4 be connected with base plate 2, spring 4 is in extended state and makes top board corner be subject to uniform pulling force, improve the stability of whole top board 1, support member 9 comprises cross reinforcing rib and further enhances braced structures, top board 1 after preventing lecturer to stand in rising rocks shakiness, improves security performance.
