Technical Field
[0001] This utility model belongs to the field of smart blackboard technology, and in particular relates to a protective shell for smart blackboards. Background Technology
[0002] A smart blackboard is a modern teaching tool that combines traditional whiteboard and projector technologies. It is a high-tech educational information product that uses computer technology to simulate all the functions of using a blackboard and electronic teaching resources in the classroom.
[0003] Some smart blackboards are typically used in conjunction with traditional blackboards, installed between two writing blackboards to facilitate teachers' daily writing. To protect the smart blackboard after use, a protective shell has been designed. This device uses two front cover plates, which can be opened and closed with the help of a limiting structure. This allows the front space of the smart blackboard to be closed and opened, thus protecting it after use and preventing accidental damage. Utility Model Content
[0004] The purpose of this invention is to provide a protective shell for a smart blackboard, which protects the smart blackboard after use to prevent accidental damage, thereby solving the aforementioned technical problems.
[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A protective shell for a smart blackboard includes a support frame: a bottom groove is provided at the bottom of the inner cavity of the support frame, and a guide rail is fixedly connected to the inner cavity of the bottom groove by bolts. Two front cover plates are slidably connected to the inner cavity of the support frame, and the bottoms of the two front cover plates are slidably connected to the inner cavity of the guide rail. A limiting structure is provided in the inner cavity of the guide rail, and two semi-circular limiting grooves are provided in the inner cavity of the limiting structure. A circular groove is provided at the bottom of the front cover plate, and a circular tube is fixedly connected to the inner cavity of the circular groove. A circular ring is slidably connected to the inner cavity of the circular tube, and a spring is welded between the circular ring and the inner cavity of the circular tube. A ball bearing is rotatably connected to the inner cavity of the circular ring.
[0006] Preferably, the surface of the ball is rolledly connected to the inner cavity of the semi-circular limiting groove, and the inner cavity of the support frame is equipped with a smart blackboard.
[0007] Preferably, the guide rail is located on the front side of the smart blackboard, and the inner cavity of the support frame is fixedly connected to two writing blackboards by bolts.
[0008] Preferably, the writing blackboards are located on the left and right sides of the smart blackboard, and rectangular grooves are provided at the bottom of both front cover plates.
[0009] Preferably, the inner cavity of the rectangular groove is rotatably connected to a roller, and the surface of the roller is rolledly connected to the inner cavity of the guide rail.
[0010] Preferably, the front side of each of the front cover plates is fixedly connected to a lever support by bolts.
[0011] The beneficial effects of this utility model are:
[0012] 1. This utility model allows the front cover to slide within the guide rail. When the position of the ball is aligned with the position of the semi-circular limiting groove, the spring's rebound force causes the ball to fall into the inner cavity of the semi-circular limiting groove, thereby restricting the position of the front cover. This achieves the purpose of protecting the smart blackboard after use and preventing accidental damage to the smart blackboard.
[0013] 2. By setting rollers, the bottom of the front cover plate can be supported in the inner cavity of the guide rail, while reducing the friction between the bottom of the front cover plate and the inner cavity of the guide rail, so that the front cover plate can slide more smoothly.
[0014] 3. By setting up a leverage support, this utility model allows the teacher to obtain a leverage point between the teacher and the surface of the front cover when the teacher pulls the front cover to slide, making it easier for the teacher to pull the front cover. Attached Figure Description

[0023] In the following description, embodiments of the protective housing for a smart blackboard according to the present invention will be described with reference to the accompanying drawings.
[0024] Example 1:
[0025] Figure 1-5 This invention illustrates a protective housing for a smart blackboard according to an embodiment of the present invention, comprising: a support frame 1; a bottom groove 2 is formed at the bottom of the inner cavity of the support frame 1, and a guide rail 3 is fixedly connected to the inner cavity of the bottom groove 2 by bolts; two front cover plates 4 are slidably connected to the inner cavity of the support frame 1, and the bottoms of the two front cover plates 4 are slidably connected to the inner cavity of the guide rail 3; a limiting structure 5 is provided in the inner cavity of the limiting structure 5, and two semi-circular limiting grooves 51 are formed in the inner cavity of the limiting structure 5; a circular groove is formed at the bottom of the front cover plate 4, and a circular tube 52 is fixedly connected to the inner cavity of the circular groove; a circular ring 53 is slidably connected to the inner cavity of the circular tube 52; and a spring is welded between the circular ring 53 and the inner cavity of the circular tube 52. Spring 54 and ring 53 are rotatably connected to ball bearings 55. The surface of ball bearings 55 is rolledly connected to the inner cavity of semi-circular limiting groove 51. A smart blackboard 6 is installed in the inner cavity of support frame 1. Guide rail 3 is located in front of smart blackboard 6. Two writing blackboards 7 are fixedly connected to the inner cavity of support frame 1 by bolts. Roller 9 is rotatably connected to the inner cavity of rectangular groove 8. The surface of roller 9 is rolledly connected to the inner cavity of guide rail 3. By setting roller 9, the bottom of front cover plate 4 can be supported in the inner cavity of guide rail 3, and the friction between the bottom of front cover plate 4 and the inner cavity of guide rail 3 can be reduced, so that front cover plate 4 can slide more smoothly.
[0026] Example 2:
[0027] Figure 1-5This invention illustrates a protective housing for a smart blackboard according to an embodiment of the present invention, comprising: a support frame 1; a bottom groove 2 is formed at the bottom of the inner cavity of the support frame 1, and a guide rail 3 is fixedly connected to the inner cavity of the bottom groove 2 by bolts; two front cover plates 4 are slidably connected to the inner cavity of the support frame 1, and the bottoms of the two front cover plates 4 are slidably connected to the inner cavity of the guide rail 3; a limiting structure 5 is provided in the inner cavity of the limiting structure 5, and two semi-circular limiting grooves 51 are formed in the inner cavity of the limiting structure 5; a circular groove is formed at the bottom of the front cover plate 4, and a circular tube 52 is fixedly connected to the inner cavity of the circular groove; the inner cavity of the circular tube 52... A circular ring 53 is slidably connected to the cavity. A spring 54 is welded between the circular ring 53 and the inner cavity of the circular tube 52. A ball bearing 55 is rotatably connected to the inner cavity of the circular ring 53. Two writing blackboards 7 are located on the left and right sides of the smart blackboard 6, respectively. A rectangular groove 8 is opened at the bottom of each of the two front cover plates 4. A lever support 10 is fixedly connected to the front side of each of the two front cover plates 4 by bolts. By setting the lever support 10, the teacher can obtain a lever point between the teacher and the surface of the front cover plate 4 when the teacher pulls the front cover plate 4 to slide, which makes it easier for the teacher to pull the front cover plate 4.
[0028] Working principle: When using this utility model, the user pulls the lever 10 to make the front cover 4 slide in the inner cavity of the guide rail 3. The roller 9 makes the front cover 4 slide more smoothly. At the same time, the support of the round tube 52 and the ring 53 allows the ball 55 to better fit the inner cavity of the guide rail 3 and roll. Then, when the position of the ball 55 is consistent with the position of the semi-circular limiting groove 51, the rebound force of the spring 54 makes the ball 55 slide downward and fall into the inner cavity of the semi-circular limiting groove 51, thereby restricting the position of the front cover 4 and protecting the smart blackboard 6. When the smart blackboard 6 needs to be used, the lever 10 is pulled again to make the front cover 4 slide so that the front cover 4 can be unfolded. This protects the smart blackboard after use and prevents accidental damage to the smart blackboard.
[0029] In summary, the protective casing for the smart blackboard works by pulling the front cover 4 to slide within the guide rail 3. When the position of the ball bearing 55 aligns with the position of the semi-circular limiting groove 51, the rebound force of the spring 54 causes the ball bearing 55 to fall into the inner cavity of the semi-circular limiting groove 51, thereby restricting the position of the front cover 4. This achieves the purpose of protecting the smart blackboard after use and preventing accidental damage to the smart blackboard.
