Description

Technical Field

[0001] The utility model relates to the technical field of teaching equipment, and more specifically to a multifunctional teaching wall chart device. Background Art

[0002] Teachers need more tools to assist teaching and make classes more interactive and interesting. As a teaching aid, wall charts need to adapt to this change and provide more flexible and diverse functions to meet teaching needs.

In addition, some existing wall chart holders are not convenient for adjustment according to the width of the picture, which leads to poor wall chart effect. At the same time, the picture may be bent, which may make some picture content inconvenient to view. Therefore, there is an urgent need for a multifunctional teaching wall chart holder to solve the above problems. Utility Model Content

[0020] The following will be combined with the drawings in the present invention to clearly and completely describe the technical solution of the present invention. In addition, the forms of the various structures described in the following embodiments are merely examples. The instrument placement rack involved in the present invention is not limited to the various structures described in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0021] Example 1

[0022] like Figures 1 to 3 As shown, this embodiment proposes a multifunctional teaching wall chart device, including a bracket 1, the bracket 1 is provided with two groups of mirror distribution, a support frame 2 is slidably inserted between the two groups of brackets 1, a card slot 3 is provided on both sides of the inner wall of the bracket 1, a first limiting block 4 is slidably inserted at both ends of one side of the support frame 2, and a second limiting block 5 is fixed at one end of the first limiting block 4, and four groups of second limiting blocks 5 are provided, a spring 6 is fixedly connected between each two groups of second limiting blocks 5, an inverted T-shaped groove is provided at both ends of one side of the support frame 2, and the middle sliding of the first limiting block 4 The second limiting block 5 and the spring 6 are slidably inserted in the inside of the inverted T-shaped groove, and the two ends of the support frame 2 are provided with through grooves. The second limiting block 5 and the spring 6 are slidably inserted in the inside of the through groove. The through groove and the inverted T-shaped groove are connected. There are multiple groups of card slots 3, and the multiple groups of card slots 3 are symmetrically and equidistantly distributed on both sides of the inner wall of the support frame 2 in a linear array. One end of the second limiting block 5 is slidably inserted in the inside of the card slot 3. There are four groups of first limiting blocks 4. The four groups of first limiting blocks 4 are respectively located at the four corners of the support frame 2. One end of each group of first limiting blocks 4 is fixedly connected to one side of each group of second limiting blocks 5;

[0023] In this embodiment, the device is first placed in a suitable position. Then, if the height of the support frame 2 needs to be adjusted, two of the first limiting blocks 4 are pressed first, so that the two first limiting blocks 4 slide toward each other, and the two first limiting blocks 4 drive the two second limiting blocks 5 to slide toward each other until one end of the two second limiting blocks 5 leave the inside of the slot 3. At this time, the spring 6 is squeezed, and the middle of the two first limiting blocks 4 slides inside the T-slot. When the two first limiting blocks 4 slide to the middle of the T-slot, the two first limiting blocks 4 are pulled so that the two first limiting blocks 4 are at one end of the T-slot. At this time, the T-slot restricts the two first limiting blocks 4 and releases the restriction on one end of the support frame 2. Then, the other two first limiting blocks 4 are pressed. The working principle is the same as the principle of the above steps, which will not be elaborated here. The restriction on the other end of the support frame 2 is released, and the height of the support frame 2 can be adjusted at this time. After the support frame 2 is pulled to the appropriate height, the two groups of first restriction blocks 4 are pushed so that the two groups of first restriction blocks 4 slide in the T-slot until they slide to the other end of the T-slot. At this time, the two groups of second restriction blocks 5 are affected by the rebound force of the spring 6, driving the two groups of second restriction blocks 5 to slide, and the two groups of second restriction blocks 5 drive the two groups of first restriction blocks 4 to slide until one end of the two groups of second restriction blocks 5 slides to the corresponding slot 3. At this time, the purpose of restricting one end of the support frame 2 is achieved, and then the other two groups of first restriction blocks 4 are pushed. The working principle is the same as the principle of the above steps, which will not be elaborated here. Then, the other end of the support frame 2 can be restricted, thereby achieving the purpose of height adjustment of the support frame 2.

[0024] Example 2

There are multiple groups of square grooves 7, and the multiple groups of square grooves 7 are equidistantly distributed on one side of the support frame 2 in a linear array. The limit block 10 is slidably inserted inside the square groove 7, and a positive magnet is provided inside one side of the square groove 7, and a negative magnet is provided inside the limit block 10.

[0026] In this embodiment, after the height adjustment is performed, if the width of the hanging chart is to be adjusted, one of the groups of limit blocks 10 is first pulled, and one of the groups of limit blocks 10 is hinged and rotated, and one end of one of the groups of limit blocks 10 leaves the inside of the square groove 7. At this time, the restriction on one of the groups of adjustment blocks 8 is released, and then one of the groups of hooks 9 is pulled, and one of the groups of hooks 9 drives one of the groups of adjustment blocks 8 to slide inside the slide groove until it slides to a suitable position, and then one of the groups of limit blocks 10 is rotated so that one end of one of the groups of limit blocks 10 is slidably inserted into the corresponding group Inside the square groove 7, then pull another set of limit blocks 10. The working principle is the same as the principle of the above steps, which will not be elaborated here. Release the restriction on the other set of adjustment blocks 8, and then pull the hooks 9 to the appropriate position according to the required width of the hanging picture, and then pull another set of limit blocks 10 to make the other set of limit blocks 10 hinged and rotated until one end of the other set of limit blocks 10 is slid and inserted into the corresponding square groove 7. Then hang the pictures to be used for teaching on the two sets of hooks 9, and then you can teach according to the content of the pictures, such as poems, etc.
