Embodiment Construction
[0012] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0013] Such as figure 1 As shown, the water-washable belt-shaped blackboard of the present embodiment includes a blackboard frame 1 and a belt-shaped blackboard 2 installed on the blackboard frame 1. The two ends of the blackboard frame 1 are symmetrically equipped with guide wheels 3 and pressure rollers 4, and the belt-shaped blackboard 2 is wound on the guide wheels 3 on both sides; the two sides of the back of the blackboard frame 1 are equipped with retractable and unwinding reels 5 through brackets, and the two ends of the strip-shaped blackboard 2 are respectively wound on the two rewinding and unwinding reels 5, and the two rewinding and unwinding reels The direction of rotation of 5 is opposite, forming the state of one receiving and one releasing; Drive motor 6 is installed on the blackboard frame 1 between the two rewinding and un...

The invention relates to a washable strip-shaped blackboard. The washable strip-shaped blackboard comprises a blackboard bracket and a strip-shaped blackboard body installed on the blackboard bracket; guiding wheels and pressing wheels are symmetrically installed at the two ends of the blackboard bracket, and the strip-shaped blackboard body winds around the guiding wheels on the two sides; retracting and releasing roll wheels are installed on the two sides of the back surface of the blackboard bracket through supports, the two ends of the strip-shaped blackboard body wind around the two retracting and releasing roll wheels respectively, and the rotation directions of the two retracting and releasing roll wheels are opposite so that the state that one conducts retraction while the other conducts release can be formed; a drive motor is installed at the part, located between the two retracting and releasing roll wheels, of the blackboard bracket and is connected to the retracting and releasing roll wheels through synchronous belts, and a switch of the drive motor is arranged in the front of the blackboard bracket; and water scrubbing devices are symmetrically installed at the two ends of the blackboard bracket. The washable strip-shaped blackboard is novel, writing pages can be updated in the teaching process without erasing dust, and therefore the teaching efficiency can be improved, dust suction can be avoided, the installation space can be saved, and cleaning can be convenient.
Description
technical field [0001] The present invention relates to a teaching tool, in particular to a blackboard. Background technique [0002] Existing blackboards are generally plates fixed on the wall or supported by fixed brackets. Due to the limited width of the classroom, the width of the blackboard is limited. When writing full of pictures and texts, it is necessary to erase the front to leave a blank space before continuing to write. There is a phenomenon of dust flying when erasing, and a certain amount of teaching time is wasted. When the existing blackboard needs to be washed with water, it can only be scrubbed with a rag soaked in water, which is inconvenient. Contents of the invention [0003] In view of this, the applicant researches and designs the existing blackboards, and provides a water-washable belt-shaped blackboard that can extend the width of use, occupy less space, save erasing time, and improve teaching efficiency. [0004] In order to solve the above pro...
