Description

Technical Field

[0001] The utility model relates to the technical field of electronic blackboards, and in particular to an expandable smart blackboard. Background Art

[0002] With the increasing popularity of electronic intelligent products, educational equipment is also constantly moving to the forefront of the field of smart devices. Electronic blackboards usually combine computers, traditional blackboards and touchpads to provide teachers and students with a more convenient teaching experience, achieve efficient blackboard display, support multimedia teaching methods, and excellent teacher-student interaction operations.

[0003] Traditional smart blackboards usually adopt a three-board design, that is, the central panel is a touch display panel, and traditional blackboards are installed on both sides. Due to the large amount of chalk dust and broken chalk near the blackboard during daily blackboard teaching, the sliding grooves under traditional blackboards that slide on both sides often accumulate broken chalk heads and flying chalk dust, causing the slides to be blocked. This is very inconvenient to clean and affects the normal operation of the equipment. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the blackboard sliding groove is easily blocked and difficult to clean, which affects the normal use of the equipment.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: an expandable smart blackboard, including a display board and two expandable boards, a sliding seat is fixedly connected to one side of the bottom end of the display board, and the two expandable boards are slidably connected to the sliding seat, a sliding groove is provided at the top of the sliding seat, and a plurality of cleaning grooves are provided through the inner wall of the bottom of the sliding groove, a cleaning bottom plate is clamped inside the cleaning groove, and a plug-in groove is provided through one side of the sliding seat and the cleaning bottom plate, and a limited plug-in plate is inserted in the plug-in groove.

[0006] As a further improvement of the present invention, the bottom end of the expansion plate is fixedly connected to a slider that is slidably connected to the slide groove.

[0007] As a further improvement of the present invention, two guide posts are fixedly connected to the top frame of the display panel, and guide grooves for the guide posts to pass through are formed through the unfolding panel.

[0008] As a further improvement of the present invention, a handle is fixedly connected to one side of the limiting plug plate.

[0009] As a further improvement of the present invention, a mounting block is fixedly connected to one side of the cleaning base plate, and a mounting groove matching the mounting block is provided at the bottom end of the sliding seat, and the mounting groove is communicated with the cleaning groove.

[0010] As a further improvement of the present invention, two finger buckles are fixedly connected to the bottom end of the cleaning base plate.

[0011] The beneficial effects of the present invention are as follows: the present invention provides a plurality of cleaning slots through the sliding seat, and a cleaning base plate is clamped at the bottom of the cleaning slot. The cleaning base plate is firmly connected to the sliding seat by the fixed limiting action of the limiting plug plate and the plug slot. When a large amount of broken chalk or chalk dust accumulates in the sliding seat, the limiting plug plate can be separated by pulling the handle outward, and then the finger buckle can be pulled downward to separate the sliding seat and the cleaning base plate. The debris accumulated in the sliding seat can be cleared out from the cleaning slot. The cleaning operation is convenient, the maintenance is convenient, and the subsequent operation of the device is effectively guaranteed. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The terms "up", "down", "left", "right", "front", "back", "front", "back", "top", "bottom" and other directional terms mentioned or possibly mentioned in this specification are defined relative to the structure of the device and are relative concepts. Therefore, they may vary depending on the location and usage of the device; therefore, these or other directional terms should not be interpreted as restrictive.

[0018] As used in this specification, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and / or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

[0019] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, the following further describes this application in detail with reference to the accompanying drawings and implementation methods. It should be understood that the implementation methods described herein are only used to explain this application and are not intended to limit this application.

[0020] The utility model provides the following Figure 1-4 As shown, an expandable smart blackboard includes a display board 1 and two expandable boards 2. A sliding seat 3 is fixedly connected to one side of the bottom end of the display board 1. The two expandable boards 2 are slidably connected to the sliding seat 3. A sliding groove 4 is provided on the top of the sliding seat 3. A plurality of cleaning grooves 5 are penetrated through the inner wall of the bottom of the sliding groove 4. A cleaning base plate 6 is clamped inside the cleaning groove 5. A plug-in groove 7 is penetrated on one side of the sliding seat 3 and the cleaning base plate 6. A limited plug-in plate 8 is inserted in the plug-in groove 7.
