These archives usually contain various forms of teaching materials, designed to support curriculum design, teaching implementation and student evaluation. Teaching material archives need to be organized, and a teaching material archive rack will be used. Teaching material archive racks are framework structures used to store, organize and manage teaching resources, usually composed of different parts or categories so that teachers can easily find the teaching materials they need.

[0003] However, the existing teaching material file rack has the following disadvantages. Since the lengths of the teaching material files are different and the width of the partition of the teaching material file rack is fixed, when the longer teaching material files are placed on the partition of fixed width, the ends will protrude to the outside of the partition, resulting in unstable placement of the teaching material files. Therefore, the existing teaching material file rack needs to be improved. Utility Model Content

[0028] During specific implementation, due to the different numbers of teaching material files placed, a small number of teaching material files cannot be stored neatly on the teaching material file rack. The No. 2 support spring 405 can be used to drive the telescopic rod 404 to push the clamping plate 406 to one side, so that the clamping plate 406 is against the two sides of the teaching material file; at the same time, the height of the clamping plate 406 is adjusted according to the height of the teaching material file. Specifically, the telescopic rod 404 drives the slider 403 to slide upward on the outside of the slide rod 402 through the clamping plate 406, and the slider 403 squeezes the No. 1 support spring 401, and then the No. 1 support spring 401 rebounds to make the slider 403 drive the telescopic rod 404 to move downward, thereby making the upper end of the clamping plate 406 against the upper surface of the teaching material file. The adjustability of the clamping plate 406 improves the regularity of the teaching material file rack.

[0029] According to 1- Figure 4 and Figure 6-Figure 7As shown, the main frame 1 and the stand 2 are jointly provided with an extension mechanism 6, a rotating shaft 7 is installed on the extension mechanism 6, an extension plate 5 is fixedly sleeved on the rotating shaft 7, a limiting mechanism 8 is installed on the inner side of the main frame 1 close to the extension mechanism 6, the extension mechanism 6 includes a support block 602, there are multiple support blocks 602, multiple support blocks 602 are all installed on the same side of the main frame 1 and the stand 2, and the rotating shaft 7 is jointly installed on multiple support blocks 602, and the rotating shaft 7 is rotatably installed on the support block 602 through bearings; a turntable 601 is fixed at one end of the rotating shaft 7, a fixing rod 604 is connected to the turntable 601, and a slide groove 603 cooperating with the fixing rod 604 is opened on the main frame 1, and the slide groove 603 is in the shape of an arc , the center of the slide groove 603 coincides with the center of the rotation shaft 7, and the slide groove 603 and the fixed rod 604 are slidably connected; the limiting mechanism 8 includes a limiting rod 802, the main frame 1 is provided with a built-in groove located just above the slide groove 603, the limiting rod 802 is installed in the built-in groove of the rotating disk 601, and the limiting rod 802 can move up and down in the built-in groove, a reset spring 801 is provided above the limiting rod 802, and the reset spring 801 is located in the built-in groove of the main frame 1, and the fixed rod 604 is provided with a limiting groove 803 that matches the lower end of the limiting rod 802; the number of the fixed rods 604 on the rotating disk 601 is provided with two, and the two fixed rods 604 correspond to the vertical state of the extension plate 5 and the horizontal state of the extension plate 5 respectively. In order to facilitate pulling the limiting rod 802, a handle can also be installed on the limiting rod 802.

[0030] In specific implementation, the lengths of teaching material files are different. When a teaching material file with a longer length is placed on a partition with a fixed width, the end of the teaching material file will protrude to the outside of the partition, resulting in unstable placement of the teaching material file. In the present invention, the limit rod 802 can be pulled upward to squeeze the reset spring 801, and one end of the limit rod 802 is disengaged from the limit slot 803, and then the turntable 601 is rotated to drive the rotating shaft 7 to rotate, and the rotating shaft 7 then drives the extension plate 5 to rotate, and the extension plate 5 is unfolded. At the same time, the turntable 601 drives the fixed rod 604 to slide upward in the slide slot 603, so that the extension plate 5 is at the same horizontal position as the placement plate 9, and then the limit rod 802 is released, so that the reset spring 801 rebounds and drives one end of the limit rod 802 to insert into the limit slot 803, limiting the position of the turntable 601, and then the extension plate 5 can provide auxiliary support for the protruding part of the teaching material file. The setting of the extension plate 5 improves the stability of the teaching material file rack.

[0031] Working principle: When using this teaching material file rack with an extension structure, first, the extension plate 5 is unfolded through the extension mechanism 6 and the limiting mechanism 8 according to the length of the teaching material file, and then the teaching material file is placed on the placement plate 9.
