Description

Technical Field

[0001] This utility model relates to the field of interactive blackboard technology, and in particular to a smart interactive blackboard with a sliding small blackboard. Background Technology

[0002] With the widespread application of information technology in education, educational informatization has become a crucial force driving educational reform and development. Traditional teaching methods are increasingly unable to meet the demands of modern education for diversified teaching tools, personalized learning experiences, and efficient integration and sharing of teaching resources. Schools and educational institutions urgently need multi-functional teaching equipment to improve teaching quality and efficiency, promote interaction and collaboration between teachers and students, and optimize the allocation and full utilization of educational resources. Touch technology has matured significantly, evolving from initial single-point touch to multi-point touch, and then to high-precision pressure-sensitive touch, providing a more convenient and natural way to interact with teaching equipment. Teachers can directly write, zoom, and move objects on the screen using their fingers or a stylus, as intuitively as writing on a traditional blackboard. This also allows for richer interactive functions, such as clicking links, dragging graphics, and handwriting recognition. The widespread adoption of network communication technology and the development of cloud computing technology enable teaching equipment to easily connect to the internet, achieving resource sharing and remote teaching. Teachers can access a vast amount of online educational resources, such as teaching courseware, video tutorials, and academic literature, and integrate them into their classroom teaching. Meanwhile, cloud computing technology provides powerful support for the storage, processing, and analysis of teaching data, making it easier for teachers to track and evaluate students' learning process and achieve personalized teaching.

[0003] In traditional teaching environments, blackboards are an important teaching tool. However, with the development of educational informatization, simple blackboards are gradually becoming insufficient to meet the diverse needs of modern teaching. Some existing teaching equipment has certain interactive functions, but it is often complex in structure, inconvenient to install and disassemble, and not convenient enough for maintenance and inspection. Therefore, we propose a smart interactive blackboard with a sliding blackboard to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide a smart interactive blackboard with a sliding blackboard to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A smart interactive blackboard with a sliding blackboard includes: an outer fixed frame and a fixed platform. An inner fixed frame is fixedly installed inside the outer fixed frame. Two motors are fixedly installed at the top of the inner fixed frame. Each of the output ends of the two motors is fixedly installed with a threaded rod. A sliding plate is threadedly connected to the threaded rod. A common upper limiting plate is fixedly installed between the two sliding plates. The upper limiting plate and the two sliding plates are slidably installed inside the inner fixed frame. A motor is fixedly installed on one side of the inner fixed frame. A threaded rod is fixedly installed at the output end of the motor. Two sliding plates are threadedly connected to the threaded rod. A side limiting plate is fixedly installed at the top of the sliding plate. Two threaded grooves with opposite directions are formed on the threaded rod. The fixed platform is disposed inside the inner fixed frame. A main interactive screen is fixedly installed on one side of the fixed platform.

[0007] Preferably, a movable blackboard is slidably installed inside the outer fixed frame. T-shaped slide bars are fixedly installed at the top and bottom of the movable blackboard. A square insert is fixedly installed on one side of the movable blackboard. A limiting slot matching the square insert is provided on the outer fixed frame. Two fixing springs are fixedly installed inside the square insert. An oblique buckle is fixedly installed on the side of the two fixing springs that are far apart from each other. A sliding plate is fixedly installed on one side of the oblique buckle.

[0008] Preferably, a collection drawer is slidably installed inside the outer fixed frame, and fixed blocks are fixedly installed on both sides of the collection drawer. Two connecting springs are fixedly installed inside the outer fixed frame, and round buckles are fixedly installed at the bottom of the connecting springs. A sliding groove matching the collection drawer and the two fixed blocks is opened inside the outer fixed frame, and a round slot matching the round buckle is opened on the fixed block.

[0009] Preferably, the inner fixed frame has sliding grooves that match the two side limiting plates and the two sliding plates, the inner fixed frame has moving sliding grooves that match the upper limiting plate and the two sliding plates, the outer fixed frame has sliding grooves that match the moving blackboard, and the top and bottom of the inner wall of the sliding groove have sliding T-grooves that match the T-shaped slide bars.

[0010] Preferably, the square insert has a sliding square groove that matches the angled buckle, the fixing spring is fixedly installed in the sliding square groove, the angled buckle is slidably installed in the sliding square groove, a limiting sliding hole is provided on one side of the sliding square groove, the pull plate is slidably installed in the limiting sliding hole, and a discharge hole is provided in the outer fixing frame, which is located above the collection drawer.

[0011] Preferably, the outer fixing frame has a circular groove that matches the circular buckle, the circular buckle is slidably installed in the circular groove, and the connecting spring is fixedly installed in the circular groove.

[0012] Preferably, a fixed blackboard is fixedly installed inside the outer fixed frame, a fixed handle is fixedly installed on one side of the movable blackboard, and multiple support plates are fixedly installed on the outside of the outer fixed frame.

[0013] In this invention, a smart interactive blackboard with a sliding blackboard is described. By sliding the blackboard, it and its top T-shaped slider slide smoothly within the sliding groove of the outer fixed frame, exposing or obscuring the main interactive screen. By starting motor one, the threaded rod one is driven to rotate, causing sliding plate one and upper limiting plate to move along the sliding groove of the inner fixed frame. By starting motor two, the threaded rod three is driven to rotate, causing sliding plate two to move the side limiting plate. Then, the fixed platform and the main interactive screen are placed inside the inner fixed frame. Then, motors one and two are started in reverse, causing the side limiting plate and upper limiting plate to cooperate to clamp and fix them. This facilitates the disassembly and maintenance of the fixed platform and the main interactive screen. When the main interactive screen is not needed, the movable blackboard is pushed, and the square plug on one side of the movable blackboard is inserted into the limiting slot on the outer fixed frame. The angled buckle pops out under the elastic force of the fixing spring and locks into the limiting slot, thus fixing the movable blackboard.

[0014] In this invention, a smart interactive blackboard with a sliding blackboard is described. By pulling the sliding plate, the inclined latch overcomes the elasticity of the fixing spring and slides into the square insert, releasing the fixation of the movable blackboard. This allows the movable blackboard to be easily pulled out for continued use. During teaching, chalk stubs and other debris are generated and can be directly discarded into the collection drawer. Some chalk stubs may be pushed onto the discharge hole during the movement of the movable blackboard and fall into the collection drawer. When there is a lot of debris in the collection drawer, pulling the drawer out causes the round latch to press against the connecting spring and disengage from the round slot on the fixing block, releasing the fixation of the collection drawer. The collected debris can then be emptied and cleaned. After cleaning, the fixing blocks on both sides of the collection drawer are aligned with the sliding grooves in the outer fixing frame and pushed in. The round latches, under the elasticity of the connecting spring, re-engage into the round slots, securing the collection drawer for future use.

[0015] This utility model has a reasonable structural design. Through the cooperation of multiple structures, it is convenient to disassemble and repair the fixed platform and the main interactive screen. The movable blackboard can cover or expose the main interactive screen at any time, adapting to different teaching scenarios. In addition, the round buckle and the collection drawer can collect debris to keep the teaching environment clean and hygienic. Attached Figure Description
