Abstract
The invention relates to an automatic blackboard cleaning device, which relates to the technical field of teaching equipment and aims to solve technical problems on the convenient cleaning of blackboards. The device comprises the blackboard, a DC motor, a moving rod, a screw rod, a guide rail and a felt, wherein the moving rod, the screw rod and the guide rail are all linear; the guide rail is provided with a guide groove coaxial with the guide rail; the screw rod is arranged at the upper end of the blackboard in a rotating way, and the axis of the screw rod is parallel to the upper edge of the blackboard; the guide rail is fixed at the lower end of the blackboard, and the axis of the guide rail is parallel to that of the screw rod; the upper end of the moving rod is sleeved with the screw rod in a threaded way, while the lower end is extended into the guide groove of the guide rail; the axis of the moving rod is vertical to that of the screw rod; the DC motor is fixed on one side of the blackboard; a power shaft of the DC motor is connected with the screw rod through a shaft; the positive and negative power ends of the DC motor are connected with an external power supply by a positive and negative rotation controller; the felt is strip-like; and the front side edge of the felt is fixedly connected with the moving rod, while a rear side edge is pressed against the board surface of the blackboard. The device provided by the invention does not influence the health of a human body when cleaning the blackboard.
Description
Technical field
The present invention relates to the technology of teaching equipment, particularly relate to a kind of technology of automatic blackboard cleaning device.
Background technology
Blackboard, blackboard eraser and chalk are the requisite teaching equipments of classroom instruction.Traditional blackboard all carries out wiping by manual mode, and this manual wiping mode is not only time-consuming but also require great effort, and shorter people is difficult to clip blackboard top.In addition,, wipe the chalk dust that falls and suck the human respiratory tract easily because during manual erasing the board, people's face can be faced blackboard directly, to the health band hidden danger.
Summary of the invention
At the defective that exists in the above-mentioned prior art, it is convenient that technical problem to be solved by this invention provides a kind of wiping, can not influence the automatic blackboard cleaning device of health.
In order to solve the problems of the technologies described above, a kind of automatic blackboard cleaning device provided by the present invention is characterized in that: comprise blackboard, direct current generator, carriage release lever, screw mandrel, guide rail and felt;
Described carriage release lever, screw mandrel and guide rail be shape linearly all, and described guide rail is provided with the gathering sill coaxial with it;
Described screw mandrel is rotatably installed in the upper end of blackboard, and its axis is parallel to the upper edge of blackboard;
Described guide rail is fixed on the lower end of blackboard, and its axis is parallel to the axis of screw mandrel;
The upper end of described carriage release lever threadably with the screw mandrel socket, its lower end is stretched in the gathering sill of guide rail, its axis normal is in the axis of screw mandrel;
Described direct current generator is fixed on a side of blackboard, and its line shaft and screw mandrel are coupling, and its positive-negative power end connects external power source through a positive and negative rotating controller;
Described felt is strip, and the front side edge and the carriage release lever of felt are affixed, and back side edge props up the plate face of blackboard.
Automatic blackboard cleaning device provided by the invention, the button that only needs operation control DC motor positive and negative rotation, can drive screw mandrel by direct current generator rotates, and then drive carriage release lever move left and right, thereby by being fixed on the felt blackboard wiping on the carriage release lever, wiping is very convenient, and the people does not need to face directly blackboard during blackboard wiping, therefore can not influence health.
Description of drawings
Fig. 1 is the structural representation of the automatic blackboard cleaning device of the embodiment of the invention.
The specific embodiment
Below in conjunction with description of drawings embodiments of the invention are described in further detail, but present embodiment is not limited to the present invention, every employing analog structure of the present invention and similar variation thereof all should be listed protection scope of the present invention in.
As shown in Figure 1, a kind of automatic blackboard cleaning device that the embodiment of the invention provided is characterized in that: comprise blackboard 1, direct current generator 2, carriage release lever 3, screw mandrel 4, guide rail 5 and felt (not shown);
Described carriage release lever 3, screw mandrel 4 and guide rail 5 be shape linearly all, and described guide rail 5 is provided with the gathering sill coaxial with it;
Described screw mandrel 4 is rotatably installed in the upper end of blackboard 1, and its axis is parallel to the upper edge of blackboard 1;
Described guide rail 5 is fixed on the lower end of blackboard 1, and its axis is parallel to the axis of screw mandrel 4;
The upper end of described carriage release lever 3 threadably with screw mandrel 4 sockets, its lower end is stretched in the gathering sill of guide rail 5, its axis normal is in the axis of screw mandrel 4;
Described direct current generator 2 is fixed on a side of blackboard, and its line shaft and screw mandrel 4 are coupling, and its positive-negative power end connects external power source through a positive and negative rotating controller (not shown);
Described felt is strip, and the front side edge of felt and carriage release lever 3 are affixed, and back side edge props up the plate face of blackboard 1.
In the embodiment of the invention, described positive and negative rotating controller is a prior art.
The embodiment of the invention is under original state, carriage release lever 3 is positioned at the left hand edge place of blackboard 1, when needing blackboard wiping 1, just changeing by positive and negative rotating controller control direct current generator 2, and then drive screw mandrel 4 is just changeing, make threadably and to move right with the carriage release lever 3 of screw mandrel 4 sockets axis along screw mandrel 4, when carriage release lever 3 moves to the right edge of blackboard 1, again by 2 counter-rotatings of positive and negative rotating controller control direct current generator, and then drive screw mandrel 4 counter-rotatings, make carriage release lever 3 be moved to the left the left hand edge place of getting back to blackboard 1 along the axis of screw mandrel 4, in the move left and right process of carriage release lever 3, can be by the felt that is fixed on the carriage release lever 3 with blackboard 1 wiped clean.
