Description
Technical field
The utility model relates to a kind of blackboard, the specifically a kind of and matching used Rotary Blackboard of electronics teaching board.
Background technology
Middle and primary schools' multimedia teaching development is very fast, and all there is the electronics teaching board in many classrooms.But there is shortcoming with the matching used blackboard of electronics teaching board: the one, the surface that several blackboards are used for writing is not in same perpendicular, and is attractive in appearance and take up room.The 2nd, middle blackboard is keeping off the electronics teaching board, if use the electronics teaching board, then the blackboard with the centre pulls to both sides; Middle blackboard slides in chute; Complex structure, and the chalk dust on the blackboard drops in the chute easily when erasing the board, and is not easy to clear up the chalk dust in the chute.
The utility model content
The purpose of the utility model is to provide a kind of and the matching used Rotary Blackboard of electronics teaching board for middle and primary schools.
The technical scheme that the utility model adopts is: saidly a kind ofly with the characteristic matching used Rotary Blackboard of electronics teaching board be: two fixed blackboard are set, and each is connected said two fixed blackboard with a backing plate, and said two backing plates are installed on the body of wall wall; A Rotary Blackboard is installed between said two fixed blackboard; Respectively by briquetting and axle sleeve of bolt, an end of said axle sleeve is provided with cylinder bodily form hole to said two fixed blackboard near Rotary Blackboard one side lower part, and the wall in said cylinder bodily form hole is provided with the tapped through hole that axis is a vertical direction; The rotating shaft of a horizontal direction is installed in said Rotary Blackboard bottom, and said rotating shaft two ends are installed in respectively in the cylinder bodily form hole of two axle sleeves; Construction bolt in the tapped through hole on the said axle sleeve.
Positive meaning: this and the matching used Rotary Blackboard of electronics teaching board are simple in structure, the surface that fixed blackboard and Rotary Blackboard are used for writing in a vertical plane, attractive in appearance and saving space.
Description of drawings
Fig. 1 is a kind of and the front view matching used Rotary Blackboard of electronics teaching board;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is 1 place's enlarged drawing among Fig. 1.
Among the figure: 1, fixed blackboard; 2, Rotary Blackboard; 3, electronics teaching board; 4, backing plate; 5, body of wall; 6, axle sleeve; 7, rotating shaft; 8, briquetting; 9, bolt.
The specific embodiment
Below in conjunction with Fig. 1 to Fig. 3; The utility model is described further: a kind of and matching used Rotary Blackboard of electronics teaching board; It is characterized in that: two fixed blackboard 1 are set, and said two fixed blackboard 1 respectively are connected with a backing plate 4, and said two backing plates 4 are installed on body of wall 5 walls; A Rotary Blackboard 2 is installed between said two fixed blackboard 1; Each fixes axle sleeves 6 by briquetting 8 and bolt 9 to said two fixed blackboard 1 near Rotary Blackboard 2 one side lower parts, and an end of said axle sleeve 6 is provided with cylinder bodily form hole, and the wall in said cylinder bodily form hole is provided with the tapped through hole that axis is a vertical direction; The rotating shaft 7 of a horizontal direction is installed in said Rotary Blackboard 2 bottoms, and said rotating shaft 7 two ends are installed in respectively in the cylinder bodily form hole of two axle sleeves 6; Construction bolt 9 in the tapped through hole on the said axle sleeve 6.
Body of wall omits and does not draw among Fig. 1.When being not suitable for machining screw on the fixed blackboard 1, then adopt tapping screw that briquetting 8 is installed on the fixed blackboard 1.When needs use electronics teaching board 3, unscrew the bolt 9 that is installed in the tapped through hole, forward Rotary Blackboard 2 main bodys to rotating shaft 7 belows, expose electronics teaching board 3.If do not re-use electronics teaching board 3, then forward Rotary Blackboard 2 to top again, the more fixing Rotary Blackboard 2 of the bolt 9 in the threaded together through hole.It is good that gap between Rotary Blackboard 2 and the electronics teaching board 3 is generally less than 10mm.
