[0001] The utility model relates to the technical field of teaching, in particular to a wall chart device for teaching which is convenient for replacing images. Background Art

[0002] A wall chart device for teaching is a tool used to assist teaching. It is usually composed of a support plate and glass. The support plate is the main structure of the wall chart device, responsible for carrying and fixing the wall chart. The glass is used to cover the surface of the wall chart to protect and display it. Its main function is to help students understand and remember knowledge more intuitively by displaying visual materials such as pictures and charts related to the teaching content. It is usually hung on the wall to facilitate the display of teaching content so that all students can clearly see and understand the displayed information. This device plays an important role in teaching. Its advantages include being intuitive, vivid, time-saving, simple, and conducive to review and consolidation.

[0003] However, the existing technical solutions still have problems:

[0004] When changing the image on the teaching display board, the outer glass needs to be opened, the image needs to be pasted into the outer frame, and then the glass needs to be installed back to its original position. Each time the image is changed, the glass needs to be removed and reinstalled, which increases the complexity and time required for replacement. For display boards that need to update content frequently, this will reduce work efficiency. In addition, frequent removal and installation of glass may also cause damage to the glass or other components, thereby increasing the cost of repair and replacement. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a teaching wall chart device that is easy to replace images, so as to solve at least one of the problems raised by the background technology, such as: making image replacement simple, fast, safe and convenient, reducing maintenance costs, and improving the flexibility and environmental protection of the display board.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a teaching wall chart device that is easy to change images, including an outer frame and glass installed on the inner side of the outer frame, symmetrical slots are opened at both ends of the side surface of the outer frame, and an illustration channel connected to the slot is opened on the outer frame between the two slots, a fixed component is slidably connected in the slot, the fixed component and the slot can be separated, and the slot and the illustration channel are both opened behind the glass.

[0007] Furthermore: the fixing assembly is composed of two identical inserts, and the length of the insert is equal to the length of the slot.

[0008] Furthermore: a magnet is embedded in the insert, and two adjacent inserts are connected by magnetic attraction.

[0009] Furthermore: pull rings are fixedly connected to both sides of the insert.

[0010] Furthermore: rollers are fixedly connected to the inner walls on both sides of the slot, and the outer sides of the rollers are rollingly connected to the outer sides of the inserting strips.

[0011] Furthermore: the number of the rollers is greater than 1, and they are arranged at equal intervals.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The utility model provides slots at the upper and lower ends of the side surface of the outer frame for inserting components that can fix images. This design allows the components to be taken out, replaced with the new image, and then inserted into the outer frame each time the image is changed, making the process of changing the image very simple. Only the component that fixes the image needs to be taken out of the slot, replaced with a new image, and then the component needs to be inserted back, thus saving time and energy required for changing the image.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] like Figures 1 to 5As shown, a teaching wall chart device which is convenient for changing images comprises an outer frame 1 and a glass 2 installed inside the outer frame 1, symmetrical slots 3 are provided at both ends of the side surface of the outer frame 1, an illustration channel 4 connected to the slots 3 is provided on the outer frame 1 between the two slots 3, a fixing component is slidably connected in the slot 3, the fixing component and the slot 3 can be detachably arranged, and the slot 3 and the illustration channel 4 are both located behind the glass 2.

[0022] like Figures 1 to 5 As shown, when the teaching wall chart device of the utility model is used, a slot 3 and an illustration channel 4 are provided on the side of the outer frame 1, so that the fixing component can be easily slid out of the slot 3, and the two ends of the image are clamped by the fixing component, and then the fixing component is inserted into the slot 3, and the new image is driven to be inserted into the outer frame 1 from the illustration channel 4, so that the image replacement is completed. The whole process is simple and fast, and there is no need to disassemble the glass 2 or other complicated operations. Since the image is inserted through the illustration channel 4, it can be ensured that the image will not be damaged or contaminated during the replacement process. At the same time, the setting of the glass 2 can protect the image from external factors such as dust and stains, and maintain the clarity and neatness of the image. At the same time, since the slot 3 and the illustration channel 4 are both located behind the glass 2, it can be ensured that the replaced image can be clearly presented behind the glass 2, and the glass 2 is used to protect the image.

[0023] like Figures 1 to 4 As shown, the fixing assembly is composed of two identical inserting strips 5 , and the length of the inserting strips 5 is equal to the length of the slot 3 .

[0024] Specifically, by setting the length of the insert 5 to be exactly equal to the length of the slot 3, the insert 5 can be fully inserted into the slot 3, ensuring that the image is accurately and stably fixed in the outer frame 1. This fixing method can prevent the image from shaking or shifting during the display process, ensuring the clarity and accuracy of viewing. The matching relationship between the insert 5 and the slot 3 makes the installation and removal process very simple and quick. The teacher or administrator only needs to slide the insert 5 out of the slot 3 to easily change the image, and then reinsert the insert 5 into the slot 3 to complete the fixation of the image. This quick replacement method improves teaching efficiency and makes the update of teaching content easy and convenient.

[0025] like Figure 5 As shown, a magnet 6 is embedded in the insert 5, and two adjacent inserts 5 are connected by magnetic attraction.

[0026] Specifically, through the magnetic attraction of the magnet 6, the inserts 5 can be quickly and firmly connected together to fix the image. Teachers or administrators do not need to use additional tools or complicated operations, but simply bring the inserts 5 close together, and they will automatically be adsorbed and fixed together. This convenient and fast fixing method improves the efficiency of changing images. The magnetic attraction of the magnet 6 can provide a stable fixing effect to ensure that the image will not loosen or shift during the display process. This stable fixing effect can keep the image flat and clear, providing a better viewing experience.

[0027] like Figures 4 to 5 As shown, pull rings 8 are fixedly connected to both sides of the insert strip 5 .

[0028] Specifically, the setting of the pull ring 8 provides an intuitive and easy-to-operate method, allowing the user to easily hold and operate the insert 5. By pulling the pull ring 8, the insert 5 can be easily slid out of the slot 3, thereby facilitating the replacement of the image. This design reduces the difficulty of operation and improves work efficiency.

[0029] like Figure 3 As shown, rollers 7 are fixedly connected to the inner walls of both sides of the slot 3, and the outer sides of the rollers 7 are rollingly connected to the outer sides of the inserting strips 5.

[0030] Specifically, the introduction of the roller 7 reduces the friction force when the insert 5 slides in the slot 3, so that when changing images, the user can more easily pull the insert 5 through the pull ring 8 to achieve rapid image change, reduce the difficulty of operation, and improve work efficiency. Due to the rolling action of the roller 7, the insert 5 will not directly contact the inner wall of the slot 3 when sliding in the slot 3, thereby avoiding direct friction and wear between the two, which helps to extend the service life of the insert 5 and the slot 3 and reduce maintenance costs.

[0031] like Figure 3 As shown, the number of rollers 7 is greater than 1, and they are arranged at equal intervals.

[0032] Specifically, by this arrangement, the number of rollers 7 is increased and arranged at equal intervals. When the insert 5 slides in the slot 3, it can contact multiple rollers 7 at the same time, thereby achieving smoother and more stable sliding, which reduces the resistance of the insert 5 during the sliding process and makes the operation easier and smoother.

[0033] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
