Description

Technical Field

[0001] This utility model relates to the field of teaching equipment technology, and in particular to a multifunctional wall chart device for teaching. Background Technology

[0002] In modern teaching activities, wall charts or projection screens are important tools for presenting teaching content. These devices are usually fixed on the classroom walls or placed on simple brackets, and their structure and function are designed around a single display purpose.

[0003] However, with the diversification of teaching models, the limitations of traditional wall charts or screens with their single function and fixed structure have been exposed in use. The fixed display angle cannot adapt to the complex spatial layout of the classroom, which can easily lead to blind spots for students in some positions due to obstructed views or poor viewing angles, thus affecting the effective transmission of information. Various physical models or teaching aids are often used in conjunction with the teaching process, and these items need to be stored separately. Teachers have to move back and forth between the display area and the storage area during the class, which not only reduces the continuity and efficiency of teaching, but also makes the overall management of teaching resources scattered and inconvenient.

[0004] Therefore, there is an urgent need for a teaching device that can integrate diverse functions, not only to flexibly adjust the display angle to suit all students, but also to integrate and store the supporting teaching aids, thereby optimizing the teaching process and improving the overall teaching experience.

[0005] Therefore, this utility model proposes a multifunctional wall chart device for teaching to address the shortcomings of the existing technology. Summary of the Invention

[0006] In view of the problems existing in the teaching wall chart device, such as limited functionality, fixed display angle leading to blind spots, and lack of storage space integrated with teaching aids causing inconvenience, this utility model aims to provide a multifunctional wall chart device for teaching with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a multifunctional wall chart device for teaching, including: a main cabinet with a storage opening on the front side; and a bracket with its top fixedly connected to the bottom of the main cabinet; the device also includes a rotating shaft rotatably disposed inside the main cabinet, a curtain wound on the rotating shaft, a rotating mechanism disposed at the bottom of the bracket, and a storage mechanism for closing the storage opening.

[0008] The rotating mechanism includes a fixed base plate and a base that is rotatably mounted on top of the base plate. The top of the base plate has an annular groove, and the bottom of the base is fixedly connected to at least two pulleys that roll within the groove. The bottom of the support is fixedly connected to the top of the base. This structure enables the entire main cabinet to rotate smoothly horizontally.

[0009] Furthermore, the storage mechanism consists of two hinged cabinets, which are connected to opposite sides of the main cabinet's storage opening via hinges. In the closed state, the two cabinets cooperate to tightly seal the storage opening, thus forming a complete cabinet structure that protects internal components such as curtains.

[0010] Preferably, in order to facilitate the storage of teaching materials, each cabinet has at least one storage board fixedly connected to its inner wall. This storage board provides a stable support platform for placing teaching models, textbooks and other items. At the same time, each cabinet has a handle fixedly connected to its outer wall for easy gripping and force application, so as to conveniently open or close the cabinet.

[0011] Preferably, in order to ensure the safety and airtightness of the device when it is not in use, a latch is rotatably provided on at least the side wall of the cabinet. When the two cabinets are in the closed state, the latch can reliably lock them to prevent the cabinet doors from being opened accidentally.

[0012] Preferably, in order to enhance the stability of the device during teaching demonstrations, each cabinet is fixedly connected to a hook at its bottom, and a latch is fixedly connected to the bottom of the main cabinet at the position corresponding to the hook; when the cabinet is opened to the predetermined position, the hook and latch engage with each other, thereby firmly fixing the cabinet door in the open position and preventing it from shaking and affecting the teaching process.

[0013] Preferably, in order to ensure the smooth and reliable long-term use of the rotating mechanism, the rotating mechanism also includes a protective plate, which is fixedly connected to the outer periphery of the base. Its lower edge extends toward the base plate and covers the opening of the slide groove. This design can effectively prevent dust, paper scraps and other debris from entering the slide groove and avoid obstructing or wearing the rollers.

[0014] Preferably, in order to achieve automated control of the curtain, a motor for driving the rotating shaft is also fixedly installed inside the main cabinet. A gear is fixedly connected to the output shaft of the motor, and the motor provides a power source for the raising and lowering of the curtain.

[0015] Preferably, in order to achieve precise power transmission, a second gear is fixedly connected to one end of the shaft, which meshes with the aforementioned first gear; through the meshing transmission of this pair of gears, the power output by the motor can be stably and efficiently transmitted to the shaft, thereby driving it to perform precise forward or reverse rotation.

[0016] Preferably, as a compact spatial layout scheme, the motor is fixedly installed on the top inner wall of the main cabinet, while the rotating shaft is rotatably installed on the top of the main cabinet and located below the motor; this vertical layout makes full use of the internal space at the top of the cabinet, making the entire drive system structure compact and not occupying additional display or storage space.

[0017] This utility model has the following beneficial effects: 1. This utility model solves the problem of fixed angles and blind spots in existing teaching display devices by setting a rotating mechanism that allows the entire device to rotate horizontally. It achieves the goal of flexibly adjusting the display direction, ensuring that all students in the classroom can have a clear view, thereby improving the teaching effect.

[0018] This utility model solves the problems of separate storage and management of teaching aids and display equipment, as well as lack of protection for core components, in the prior art by setting up an openable cabinet with an internal storage panel in front of the main cabinet. When the cabinet is closed, it can protect the main cabinet. This achieves the technical effect of integrating teaching aid storage and equipment protection, facilitating centralized management of teaching resources, and improving equipment durability.

[0019] This utility model integrates multiple functions such as electronically controlled screen opening and closing, teaching aid storage, and rotating display into one integrated design, solving the problems of cumbersome teaching preparation processes and low operational efficiency in the prior art. It simplifies the teaching process and realizes one-stop operation for retrieving teaching aids, unfolding the screen, and adjusting the angle, thereby significantly improving the efficiency of teaching preparation and display.

In this embodiment, the motor 5 is preferably fixedly installed on the top inner wall of the main cabinet 1, while the rotating shaft 6 is rotatably installed on the top of the main cabinet 1 and located below the motor 5. This layout structure is compact and can effectively utilize the internal space of the main cabinet 1.

[0028] Working principle: When teaching is required, storage mechanism 2 can be used. First, open the latch 207 on the cabinet 201, then grasp the handle 206 and pull the cabinet 201. The cabinet 201 will open to both sides under the fixing action of the hinge 202, thus revealing the interior of the main cabinet 1. There are multiple storage panels 203 on the inner wall of the cabinet 201. The storage panels 203 can be used to store teaching-related models and items for easy access during teaching. After the cabinet 201 is opened, the hook 204 at the bottom of the cabinet 201 and the latch 205 at the bottom of the main cabinet 1 can be engaged to fix the cabinet 201. The top of the main cabinet 1... The unit is equipped with a motor 5. After opening the storage mechanism 2, the motor 5 is operated by remote control. The motor 5 drives gear 8, which in turn drives gear 9, which meshes with gear 8. Gear 9 then drives the rotating shaft 6 to rotate. As the rotating shaft 6 rotates, the screen 7 will slowly unfold. Once fully unfolded, the motor 5 is turned off. At this time, the projector can be used to project the images to be displayed onto the screen 7. After the teaching is completed, the motor 5 is turned on again to retract the screen 7, close the cabinet 201, and lock it with the latch 207. The storage mechanism 2 can not only store teaching materials, but also provide a certain degree of protection for the interior of the main cabinet 1, achieving multiple effects. The main cabinet 1 is supported by a bracket 4 at its bottom. The bottom of the bracket 4 has a rotating mechanism 3. During teaching, there are bound to be blind spots in the field of vision, making it impossible to see everyone. This can be adjusted using the rotating mechanism 3. The base 301 provides more solid support for the bracket 4. The bottom of the base 301 has two pulleys 303. Both pulleys 303 slide in the annular groove 304 opened at the top of the base plate 305. The protective plate 302 can prevent objects from entering the interior of the annular groove 304, so that it will not be stuck due to foreign objects. The rotating mechanism 3 can not only provide stable support for the bracket 4 and the main cabinet 1, but also allow it to be flipped to provide a wider display angle.
