Abstract
A kind of portable Revolving blackboard.It comprises: blackboard and turning part; Wherein: blackboard is Dual-side blackboard, and its top is connected with turning part by a swingle, and turning part is fixed on the body of wall in classroom by fixed bar; Turning part is a rotation switching mechanism, and it turns over turnback after blackboard can being lifted certain angle again, thus blackboard can be used alternatingly on two sides.Described turning part is made up of horizontal rotating shaft and vertical rotation axis, and horizontal rotating shaft is used for realizing blackboard and upwards lifts, and vertical rotation axis is used for realizing blackboard upset.The portable Revolving blackboard that the utility model provides has reasonable in design, easy to use and advantages such as practicality.
Description
Technical field
The utility model relates to a kind of teaching aid, particularly relates to a kind of portable Revolving blackboard.
Background technology
In school, teacher in the class, needs to write on blackboard, because the plate face of blackboard is limited, just needs often to have write to have wiped and writes, lose time very much.
Summary of the invention
In order to solve the problem, the purpose of this utility model is to provide a kind of portable Revolving blackboard.
In order to achieve the above object, the portable Revolving blackboard that the utility model provides comprises: blackboard and turning part; Wherein: blackboard is Dual-side blackboard, and its top is connected with turning part by a swingle, and turning part is fixed on the body of wall in classroom by fixed bar; Turning part is a rotation switching mechanism, and it turns over turnback after blackboard can being lifted certain angle again, thus blackboard can be used alternatingly on two sides.
Described turning part is made up of horizontal rotating shaft and vertical rotation axis, and horizontal rotating shaft is used for realizing blackboard and upwards lifts, and vertical rotation axis is used for realizing blackboard upset.
The portable Revolving blackboard that the utility model provides has reasonable in design, easy to use and advantages such as practicality.
Accompanying drawing explanation
The front view of the portable Revolving blackboard that Fig. 1 provides for the utility model.
The side view of the portable Revolving blackboard that Fig. 2 provides for the utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the portable Revolving blackboard that the utility model provides is described in detail.
As shown in Figure 1 and Figure 2, the portable Revolving blackboard that the utility model provides comprises: blackboard 1 and turning part 2; Wherein: blackboard 1 is Dual-side blackboard, and its top is connected with turning part 2 by a swingle, and turning part 2 is fixed on the body of wall in classroom by fixed bar; Turning part 2 is a rotation switching mechanism, and it turns over turnback after blackboard 1 can being lifted certain angle again, thus blackboard 1 can be used alternatingly on two sides.
Described turning part 2 is made up of horizontal rotating shaft and vertical rotation axis, and horizontal rotating shaft is used for realizing blackboard 1 and upwards lifts, and vertical rotation axis is used for realizing blackboard 1 and overturns.
The portable Revolving blackboard that the utility model provides can be used alternatingly by tow sides, when the front of blackboard 1 is write completely, first blackboard 1 upwards can be lifted by turning part 2, and then revolve turnback and carry out turn-over, and then blackboard 1 is lowered into vertical position, this makes it possible to the turn-over continuing to use blackboard 1, thus save the time erased the board, very convenient.
