The specific embodiment
Below, with the specific embodiment the utility model is described in further detail in conjunction with the accompanying drawings:
To shown in Figure 8, the set composite of the utility model electronic whiteboard and blackboard comprises: base plate, framework 1 and float plate 4 as Fig. 1; Described base plate comprises blackboard 2 and electronic whiteboard 3; Described blackboard 2 and electronic whiteboard 3 assemblies in framework 1 on fix in the low groove 12 and with framework 1 and body of wall, the length sum of described electronic whiteboard and blackboard is the total length of this device, described electronic whiteboard 3 can be arranged on the left and right sides either side of framework 1, electronic whiteboard 3 decides the installation site, the left and right sides of electronic whiteboard usually according to the position of projector, its opposite side is provided with blackboard 2.Described float plate 4 is arranged on the front of described blackboard 2 and electronic whiteboard 3.The upper and lower side frame groove 12 of described frame 1 is inside and outside two grooves, also can be metal track, and described blackboard 2 and electronic whiteboard 3 are arranged in the inner groovy 10; The two ends up and down of described float plate 4 are respectively equipped with pulley 8, and described pulley 8 embeds in the outer groove 11 of upper and lower side frames 12, but outside in the groove 11 float plate by the pulley move left and right.The length that the length of described blackboard 2 only is larger than electronic whiteboard 3 gets final product, can cover electronic whiteboard fully when only moving to electronic whiteboard the place ahead for assurance float plate 4, in order to avoid electronic whiteboard is damaged, the length of described float plate 4 is identical with the length of blackboard 2, wherein said float plate, the bottom blackboard, the electronic whiteboard height is all identical, and the side frame of its framework can be shape or engineering plastics.One side of described float plate 4 is provided with snap close 5, and the position of electronic whiteboard is depended in the position of snap close, and when the electronic whiteboard on the left side, snap close just is installed on the left border of float plate, when electronic whiteboard on the right, snap close just is installed on the right side of float plate; Opposite side in the float plate that snap close 5 is installed is provided with dark handle 16; the user can conveniently use; be provided with lockhole 14 on the side frame corresponding and with snap close 5 adaptive places with snap close 5; the outside of described lockhole 14 is provided with lock pin 6; when need not to use electronic whiteboard; only need float plate is moved to the place ahead of electronic whiteboard; snap close 5 slips in the lockhole 14 and makes the safety lock closure by lock pin 6; thereby protection electronic whiteboard; key being inserted in the keyhole 7 float plate when needs use can move left and right, uses as required.On the frame of the left and right sides of described framework 1, also be respectively equipped with packing ring 17 and wiring hole 15, the material of described packing ring can be rubber, when mobile float plate, the side of movable plate can touch with the left and right sides edge joint of framework 1, avoid causing the sound, also can prevent device damage, wiring hole is arranged on the inboard of frame, i.e. a side of inner groovy 10.Described float plate 4 is a blackboard, its bottom is provided with scraping blade 13, described scraping blade 13 is preferably disposed on the outside of 2 pulleys of lower frame, and two ends are provided with dust hole 9 on the outer groove 11 of described lower frame 12, and the dust scraping blade is just released the dust hole with the dust in the groove when the move left and right float plate.So both guaranteed that float plate can normally move, dust can have been cleaned out again simultaneously.
