Description

Technical Field

[0001] This utility model belongs to the technical field of electronic class sign protective cover, and in particular relates to a detachable electronic class sign protective cover. Background Technology

[0002] Electronic class signs, as an important part of campus culture construction and digital construction, are widely used at the entrances of classrooms in schools. They have functions such as high-definition display and interactive data sharing, and can realize multiple applications such as class attendance, information release, and data update and maintenance.

[0003] Electronic class signs are typically installed on the exterior walls of classrooms, protruding and exposed without any protective structure. This makes them vulnerable to impacts, scratches, and corrosion from dust and moisture. Such damage can affect their normal use, shorten their lifespan, and increase maintenance and replacement costs. Traditional electronic class sign covers use screws or glue for installation and removal, requiring tools and making installation and removal inconvenient. Therefore, a detachable electronic class sign cover is needed to facilitate installation and removal, thus improving the protection and use of the electronic class signs. Utility Model Content

[0004] The purpose of this invention is to provide a detachable electronic class sign protective cover, which allows for easy installation and removal of the cover, thereby facilitating the use of the electronic class sign and solving the problems mentioned in the background art.

[0006] Preferably, the surface of the protective cover has two symmetrical bevels, and the four corners of the front of the fixing frame are provided with positioning holes.

[0007] Preferably, positioning rods are fixedly connected to the four corners of the inner wall of the protective cover, and the positioning rods and positioning holes are used in conjunction.

[0008] Preferably, a transparent glass is embedded in the surface of the protective cover, and the electronic class sign is located in the inner cavity of the fixed frame, which is located in the inner cavity of the protective cover.

[0009] Preferably, the arc-shaped fastener has a certain elasticity and can deform, and the limiting groove is a T-shaped groove.

[0010] The beneficial effects of this utility model are:

[0011] 1. This utility model achieves convenient installation and removal of the protective cover by having the inclined surface contact the arc-shaped fastener and pushing the protective cover backward. The arc-shaped fastener is squeezed by the protective cover, causing it to deform and enter the groove. When the groove is horizontally aligned with the limiting groove, the arc-shaped fastener rebounds and enters the limiting groove, allowing the protective cover to be installed on the surface of the fixed frame. When an object is inserted into the hole and the limiting plate is pushed, the limiting plate drives the push plate to push the arc-shaped fastener, causing the arc-shaped fastener to disengage from the limiting groove, thereby removing the protective cover from the surface of the fixed frame. This achieves the purpose of convenient installation and removal of the protective cover, thus facilitating the use of the electronic class sign protective cover.

[0012] 2. This utility model uses a combination of positioning holes, positioning rods, and transparent glass to align the positioning rods on the surface of the protective cover with the positioning holes and insert the positioning rods into the inner cavity of the positioning holes, thereby further facilitating the installation of the protective cover and protecting the electronic class sign.

[0020] In the following description, embodiments of the detachable electronic class sign protective cover of the present invention will be described with reference to the accompanying drawings.

[0021] Figure 1-4 This invention illustrates a detachable electronic class sign protective cover according to an embodiment of the present invention. It includes a mounting plate 1, which is fixedly mounted on a wall using expansion screws. An electronic class sign 2 is fixedly mounted on the front of the mounting plate 1. A fixing frame 3 is fixedly connected to the front of the mounting plate 1, and a protective cover 4 is provided on the front of the fixing frame 3. A transparent glass 15 is embedded in the surface of the protective cover 4. The electronic class sign 2 is located within the cavity of the fixing frame 3, and the fixing frame 3 is located within the cavity of the protective cover 4. Positioning rods 14 are fixedly connected to the four corners of the inner wall of the protective cover 4. The positioning rods 14 cooperate with positioning holes 13. Through the cooperation of the positioning holes 13, positioning rods 14, and transparent glass 15, the positioning rods 14 on the surface of the protective cover 4 are aligned with the positioning holes 13, and the positioning rods 14 are inserted into the positioning holes 13. The inner cavity of the protective cover 4 further facilitates the installation of the protective cover and protects the electronic class sign. The surface of the protective cover 4 has two symmetrical bevels 12. The four corners of the front of the fixed frame 3 are provided with positioning holes 13. The left and right sides of the fixed frame 3 are provided with arc-shaped fasteners 5. The arc-shaped fasteners 5 have a certain elasticity and can deform. The limiting groove 8 is a T-shaped groove. The two arc-shaped fasteners 5 are symmetrical to each other. The left and right sides of the fixed frame 3 are provided with grooves 6. The inner wall of the grooves 6 has two symmetrical extension grooves 7. The inner wall of the protective cover 4 has two symmetrical limiting grooves 8. The limiting grooves 8 and the arc-shaped fasteners 5 are used together. The inner cavity of the limiting groove 8 is provided with a limiting plate 9. The surface of the limiting plate 9 is fixedly connected with a push plate 10. The inner wall of the limiting groove 8 is provided with an insertion hole 11. The insertion hole 11 penetrates the protective cover 4.

[0022] Working principle: When using this utility model, the user picks up the protective cover 4, causing the inclined surface 12 of the protective cover 4 to contact the surface of the arc-shaped fastener 5. Then, by pushing the protective cover 4 backward, the arc-shaped fastener 5 is subjected to a squeezing force from the protective cover 4, causing it to deform. This allows the exposed portion of the arc-shaped fastener 5 to enter the groove 6, and both ends of the arc-shaped fastener 5 move within the cavity of the extension groove 7. When the groove 6 and the limiting groove 8 are aligned horizontally, the arc-shaped fastener 5 rebounds and deforms, entering the cavity of the limiting groove 8, thus installing the protective cover 4 on the surface of the fixing frame 3. When any object that can be inserted into the socket 11 is inserted into the socket 11 and the limiting plate 9 is pushed, the limiting plate 9 causes the push plate 10 to push the arc-shaped fastener 5, causing the arc-shaped fastener 5 to deform and disengage from the limiting groove 8, thereby removing the protective cover 4 from the surface of the fixed frame 3. This achieves the purpose of conveniently installing and removing the protective cover, thus facilitating the use of the electronic class sign protective cover. By using the positioning hole 13, the positioning rod 14 and the transparent glass 15 together, the positioning rod 14 on the surface of the protective cover 4 is aligned with the positioning hole 13 and inserted into the inner cavity of the positioning hole 13, thereby further facilitating the installation of the protective cover and protecting the electronic class sign.

[0023] In summary, this detachable electronic class sign protective cover works by having the inclined surface 12 contact the arc-shaped fastener 5, pushing the protective cover 4 backward. This causes the arc-shaped fastener 5 to deform under the pressure of the protective cover 4, allowing it to enter the groove 6. When the groove 6 is horizontally aligned with the limiting groove 8, the arc-shaped fastener 5 springs back, entering the limiting groove 8, thus installing the protective cover 4 on the surface of the fixed frame 3. When an object is inserted into the socket 11 and the limiting plate 9 is pushed, the limiting plate 9 drives the push plate 10 to push the arc-shaped fastener 5, causing it to disengage from the limiting groove 8, thereby removing the protective cover 4 from the surface of the fixed frame 3. This achieves the purpose of conveniently installing and removing the protective cover, thus facilitating the use of the electronic class sign protective cover.
