Specific embodiment

It is illustrated below in conjunction with preferred embodiment of the attached drawing to the utility model, it should be understood that described herein excellent It selects embodiment to be only used for describing and explaining the present invention, is not used to limit the utility model.

Embodiment: as shown in Figure 1-3, the utility model provides a kind of technical solution, a kind of stand alone type lifting is multi-functional black Plate, including blackboard body 1,1 bottom of blackboard body are equipped with fixed plate 4, and 4 top of fixed plate offers fixing groove 2, fixing groove 2 Two sides offer placing groove 3, and 4 outer surface of fixed plate is equipped with side plate 8, in order to do not use blackboard body 1 when, can be by side Plate 8 is folded, so that side plate 8 merges with fixed plate 4, is taken in blackboard body 1 in pedestal 5 to facilitate, side plate 8 and fixation Plate 4 is connected by shaft, and 8 top of side plate offers accumulator tank 9, and 4 bottom of fixed plate is equipped with pedestal 5, for convenience by blackboard Ontology 1 is gone up and down, so that blackboard body 1 goes up and down more smooth, the phenomenon that avoiding the occurrence of Caton, 5 inside two sides of pedestal are equal Sliding rail is installed, it is more stable in order to facilitate blackboard body 1 is fixed, it avoids when being write to blackboard body 1, generates It shakes, influences the quality of the teaching of teacher, blackboard body 1 is connected by a snap with fixed plate 4, for the ease of by blackboard body 1 It is moved, pedestal 5 is avoided to be drawn without place, and increase the labour of user, 5 liang of lateral roofs of pedestal are mounted on Pull ring.

5 outer surface of pedestal, two middle side part is mounted on storage pocket 7, and 5 bottom end of pedestal is equipped with chassis 6, and 5 top of pedestal opens up There is loose slot 10,5 inner bottom center position of pedestal is equipped with mounting base 15, and 15 top of mounting base offers limiting slot 14, Hydraulic cylinder 16, the model LW-Q70L of hydraulic cylinder 16 are installed inside limiting slot 14, and are electrically connected with city, hydraulic cylinder 16 pushes up End is connected with hydraulic stem 17, and 17 top of hydraulic stem is equipped with support plate 18, and 18 top two sides of support plate are mounted on cushion block 12, and two A 12 top of cushion block is mounted on support rod 13, and 13 top of support rod is equipped with top plate 11, for convenience by fixed plate 4 and top plate 11 carry out disassembly installation, so as to be cleared up and replaced blackboard body 1, improve the quality of teaching, fixed plate 4 and top plate 11 are bolted.

6 bottom end of chassis opens up fluted 19, and 19 inside two sides of groove are mounted on connecting rod 20, two 20 appearances of connecting rod Face is mounted on roller bearing 21.

The working principle and process for using of the utility model: when teacher imparts knowledge to students, start hydraulic cylinder 16, so that hydraulic Bar 17 drives support plate 18 to be risen, and the limiting slot 14 opened up by mounting base 15 can keep away 16 fixing-stable of hydraulic cylinder Exempt from when hydraulic cylinder 16 works, shaking and blackboard body 1 being caused to be shaken occur in hydraulic cylinder 16, and is unfavorable for further imparting knowledge to students, and supports Plate 18 is risen the top plate 11 of connection by support rod 13, so that blackboard body 1 rises to suitable position, so as to convenient Viewer's viewing, avoids blackboard body 1 from being fixed on the same position for a long time, is easy to cause viewer to generate feeling of fatigue, or even see The person's of seeing viewing meeting for a long time not only influences the comfort level of viewer so that body generation disease, and also will affect health, no Conducive to watching for a long time.

Fixing groove 2 can prevent 1 fixing-stable of blackboard body when writing, shaking and influencing to teach occur in blackboard body 1 Efficiency, with chalk in the break flour that blackboard body 1 is write and generates, passes through accumulator tank 9 when teacher uses blackboard body 1 The break flour of generation can be focused on, reduce the workload of cleaning person, and can be with by placing groove 3 and storage pocket 7 The apparatus and blackboard eraser write in blackboard body 1 are stored, can reduce the work of a variety of writing appliances of teacher's carrying Amount can clear up the break flour in accumulator tank 9 when not using blackboard body 1, swing side plate 8, so that side plate 8 and solid Fixed board 4 merges, and drops to inside pedestal 5 blackboard body 1 by hydraulic cylinder 16, is saved, and then pushes pedestal 5, passes through The roller bearing 21 installed in groove 19, blackboard body 1 can be moved, and can effectively expand blackboard body 1 uses model It enclosing, improves the efficiency of teaching, avoiding blackboard body 1 because excessive without can be carried out movement, not only increase the cost used, and It is restricted the use scope of blackboard body 1.

Finally, it should be noted that being not limited to this reality the foregoing is merely the preferred embodiment of the utility model With novel, although the utility model is described in detail with reference to the foregoing embodiments, come for those skilled in the art Say, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic into Row equivalent replacement.Within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on, should all It is included within the scope of protection of this utility model.
