[0019] Example 1: A smart classroom display frame includes a frame 1, a telescopic frame 2, a connecting frame 3, and two fixing components 4. The frame 1, telescopic frame 2, and connecting frame 3 are sequentially fitted from the outside to the inside. The telescopic frame 2 is slidably fitted with the frame 1. Several slots 5 are provided on both sides of the connecting frame 3 in the horizontal direction. Fixing components 4 are provided at both ends of the telescopic frame 2 in the horizontal direction, and the two fixing components 4 are symmetrically arranged. The connecting frame 3 and the telescopic frame 2 are detachably connected through the slots 5 and the fixing components 4.

[0020] The fixing component 4 includes a sliding cavity 401, a through cavity 402, a sliding rod 403, an operating rod 404, several openings 405, several L-shaped locking blocks 406, and an elastic element 407.

[0022] A plurality of openings 405 are linearly arranged at equal intervals on the inner side of the telescopic frame 2, and the plurality of openings 405 are connected to the sliding cavity 401; each of the plurality of openings 405 is provided with a locking block 406, and the locking block 406 is fixedly connected to the sliding rod 403, and the locking block 406 slides with the telescopic frame 2 at the opening 405.

[0023] The elastic element 407 is located between the upper part of the sliding rod 403 and the top of the sliding cavity 401, and both ends of the elastic element 407 are connected to the sliding rod 403 and the telescopic frame 2.

[0024] The following detailed description of Embodiment 1 of the present invention, in conjunction with the accompanying drawings, illustrates many specific details to provide a comprehensive understanding of the embodiments of the present invention for ease of explanation.

[0025] like Figures 1-7 As shown, the frame 1 provides a fixed space for the display screen 16 to be mounted on the wall. The connecting frame 3 is fixed to the frame of the display screen 16, and the telescopic frame 2 is used to connect the frame 1 and the connecting frame 3, and the telescopic frame 2 is slidably connected to the frame 1. When the telescopic frame 2 is pulled out of the frame 1, space is provided for the assembly and disassembly of the telescopic frame 2 and the connecting frame 3. The assembly and disassembly of the telescopic frame 2 and the connecting frame 3 are completed by the fixing component 4. When assembling the connecting frame 3 and the telescopic frame 2, first push the operating lever 404 upward. The operating lever 404 pushes the sliding rod 403 to move upward in the sliding cavity 401, thereby indirectly causing the locking block 406 to move upward. Then, align the locking slot 5 of the connecting frame 3 with the locking block 406. At this time, release the operating lever 404, and the spring on the upper part of the sliding rod 403 that was compressed by the pushing force returns to its original state, so that the locking block 406 locks the connecting frame 3 through the locking slot 5, thereby connecting the screen and the sliding frame. Repeat the above process to quickly remove the display screen 16 and the telescopic frame 2. With the display screen 16 connected to the telescopic frame 2 via the connecting frame 3, the telescopic frame 2 is pushed into the frame 1 to achieve the effect of fixing the display screen 16 to the wall and storing the fixing component 4.

[0026] Example 2: Based on Embodiment 1, the telescopic frame 2 has a groove 14 at its bottom, and the frame 1 has a groove 15 at the corresponding position of the groove 14. Several sliding grooves 6 are formed at both ends of the inner side of the frame 1, and several sliders 7 are formed at both ends of one side of the telescopic frame 2. The sliders 7 are connected to the telescopic frame 2, and the telescopic frame 2 and the frame 1 slide together via the sliders 7 and the sliding grooves 6. Elastic clips 10 are provided on both sides of the bottom of the telescopic frame 2, and the elastic clips 10 are connected to the telescopic frame 2. Two grooves 11 are formed at the bottom inner side of the frame 1, and the grooves 11 correspond to the positions of the elastic clips 10. The telescopic frame 2 and the frame 1 are engaged via the elastic clips 10 and the grooves 11.

[0027] The following detailed description of Embodiment 2 of the present invention is provided in conjunction with the accompanying drawings. In the following detailed description, many specific details are set forth to facilitate explanation and to provide a comprehensive understanding of the embodiments of the present invention.

[0028] like Figures 4-6 As shown, by passing through the slot 15 and pulling the slot 14, the telescopic frame 2 can be easily pulled out of the frame 1. The telescopic frame 2 and the frame 1 are slidably connected by the slider 7 and the slide groove 6, making the pulling between the telescopic frame 2 and the frame 1 smoother. At the same time, the telescopic frame 2 and the frame 1 are provided with elastic buckles and grooves 11, which can fix the position of the telescopic frame 2 when it is placed in the frame 1, and prevent the telescopic frame 2 from sliding out of the frame 1 due to external forces.

[0029] Example 3: Based on Embodiments 1 and 2, the telescopic frame 2 has a slot 8 inside, and the slot 8 is located on one side of the through cavity 402. A retaining strip 9 is provided at the bottom of the sliding rod 403, and the retaining strip 9 is fixedly connected to both the sliding rod 403 and the operating rod 404. The retaining strip 9 matches the slot 8. A throttle 12 is provided at the bottom of the operating rod 404, and the throttle 12 is connected to the operating rod 404. A friction part is provided on the surface of the throttle 12. A placement slot 13 is provided on the frame 1 corresponding to the positions of the operating rod 404 and the throttle 12.

[0030] The following detailed description of Embodiment 3 of the present invention, in conjunction with the accompanying drawings, illustrates many specific details to provide a comprehensive understanding of the embodiments of the present invention for ease of explanation.

[0031] like Figure 6 and Figure 7As shown, by pushing the operating lever 404 upward and rotating the handle 12, the locking strip 9 can be disengaged from the slot 8 and locked in the sliding cavity 401. At this time, the sliding rod 403 is in the rising state and does not fall, which facilitates the subsequent docking of the connecting frame 3 and the telescopic frame 2. After the connecting frame 3 is connected to the telescopic frame 2, turning the operating lever 404 back will allow the locking strip 9 to return to the slot 8. At this time, the sliding rod 403 returns to its original position, and the locking block 406 on the sliding rod 403 engages with and fixes the connecting frame 3.

[0032] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
