Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. Example

[0023] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0024] A multifunctional multimedia teaching LED display screen comprises a frame 1, a slide rail 101 is installed at the top and bottom of the inner side of the frame 1, a first blackboard 2 and a second blackboard 3 are installed inside the slide rail 101, handles 4 are symmetrically installed outside the first blackboard 2 and the second blackboard 3, an LED screen 5 is installed between the first blackboard 2 and the second blackboard 3, and a disassembly component 6 is installed on the back of the LED screen 5;

[0025] The disassembly assembly 6 is used to quickly disassemble the LED screen 5 from the inside of the frame 1 .

[0026] For further information, see Figure 1 , Figure 2 , Figure 3 and Figure 4In this embodiment, the disassembly component 6 includes a fixed plate 601, a connecting shaft 602, a rotating plate 603, a slide plate 604, a linkage rod 605 and a clamping rod 606. The fixed plate 601 is installed in the middle of the inner side of the frame 1, the connecting shaft 602 is installed in the middle of the fixed plate 601, the rotating plate 603 is installed on the outside of the connecting shaft 602, and the slide plate 604 is symmetrically installed at the left and right ends of the fixed plate 601. The linkage rod 605 is installed between the rotating plate 603 and the slide plate 604, and the clamping rod 606 is installed on the outside of the slide plate 604 and is located on the outside of the LED screen 5. Education is the whole process of cultivating a new generation to prepare for social life. During class, the teacher A blackboard 2 and a second blackboard 3 are unfolded to both sides along the slide rail 101, so that the LED screen 5 is exposed to the outside, and the LED screen 5 is used for teaching demonstration to fully improve the interest of teaching. When the LED screen 5 is damaged, the operator holds the bottom of the LED screen 5 with both hands, and then rotates the connecting shaft 602 to realize that the rotating plate 603 rotates with the connecting shaft 602, so that the linkage rod 605 is unfolded to both sides and is in a parallel state, so that the driving force is transmitted to the slide plate 604, and the slide plate 604 drives the clamping rod 606 to move away from each other, so that the LED screen 5 automatically falls into the hands of the operator, and the disassembly work is easily completed.

[0027] Among them, see Figure 1 , Figure 2 and Figure 3 In this embodiment, a block is installed on one side of the slide plate 604 close to the fixed plate 601, and a track 607 is installed inside the block. The slide plate 604 is connected to the fixed plate 601 through the track 607. The design of the track 607 is used to limit the slide plate 604, so that the slide plate 604 can move linearly along the track 607 under the driving force of the linkage rod 605, thereby effectively preventing the slide plate 604 from deflecting during the movement.

[0028] Furthermore, please see Figure 1 , Figure 2 and Figure 3 In this embodiment, springs 608 are installed between the slides 604, and the two groups of slides 604 are connected by the springs 608. Through the design of the springs 608, when the LED screen 5 is installed, the springs 608 can be extended and contracted to store energy, so as to reset the slides 604.

[0029] For further information, see Figure 1 , Figure 2 , Figure 3 and Figure 4In this embodiment, the clamp rod 606 is designed in an L-shaped structure, and a receiving groove is provided inside the clamp rod 606. The LED screen 5 is connected to the clamp rod 606 through the receiving groove. Through the L-shaped structure design of the clamp rod 606, four groups of clamp rods 606 will wrap the four corners of the LED screen 5 to prevent the corners from being bumped.

[0030] For further information, see Figure 1 , Figure 2 , Figure 3 and Figure 4 In this embodiment, a rotating wheel 609 is installed at the corner inside the clamping rod 606, and two groups of connecting rods 610 are installed outside the rotating wheel 609. The two groups of connecting rods 610 are designed with a 90-degree structure. A clamping wheel 611 is installed at one end of the connecting rod 610 away from the rotating wheel 609. When the LED screen 5 is installed inside the accommodating groove, the clamping wheel 611 contacts the LED screen 5, thereby squeezing the clamping wheel 611, so that the connecting rod 610 swings, and the clamping wheel 611 is fitted to the LED screen 5.

[0031] For further information, see Figure 1 , Figure 2 and Figure 3 In this embodiment, bolts are installed at the four corners of the fixing plate 601, and the fixing plate 601 is connected to the frame 1 through the bolts. When the entire LED screen 5 needs to be disassembled, the fixing plate 601 and the frame 1 are separated by rotating the bolts.

[0032] In this embodiment, the implementation scenario is specifically as follows: by unfolding the first blackboard 2 and the second blackboard 3 to both sides along the slide rail 101, the LED screen 5 is exposed to the outside, and the LED screen 5 is used for teaching demonstration to fully improve the teaching interest. When the LED screen 5 is damaged, the operator holds the bottom of the LED screen 5 with both hands, and then rotates the connecting shaft 602 to realize that the rotating plate 603 rotates with the connecting shaft 602, so that the linkage rod 605 is unfolded to both sides and is in a parallel state, so that the driving force is transmitted to the slide plate 604, and the slide plate 604 drives the clamping rod 606 to move away from each other, so that the LED screen 5 automatically falls into the hands of the operator, and the disassembly work is easily completed. Through the L-shaped structure design of the clamping rod 606, the four groups of clamping rods 606 will wrap the four corners of the LED screen 5. When the clamping wheel 611 contacts the LED screen 5, the clamping wheel 611 is squeezed, so that the connecting rod 610 swings, and the clamping wheel 611 is fitted to the LED screen 5 to prevent the corners from being bumped.

[0033] Although 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.
