Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0034] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] Example 1: See Figure 1-Figure 4 The present invention provides a technical solution: A multifunctional teaching board for English ideological and political education, comprising a base 1, a telescopic rod 2 is fixedly connected to the top of the base 1, a slide groove 5 is opened on the left and right sides of the outer wall of the telescopic rod 2, a first spring 6 is fixedly connected to the bottom of the slide groove 5, an electronic board 4 is fixedly connected to the top of the telescopic rod 2, and also includes:

[0036] The pressing mechanism 7 includes a first bottom plate 701, the telescopic rod 2 passes through the first bottom plate 701 and is fixedly connected thereto, a protective shell 710 is fixedly connected to the top of the first bottom plate 701, a sliding rod 705 is provided on the inner wall of the protective shell 710, both upper and lower ends of the sliding rod 705 are fixedly connected to the inner wall of the protective shell 710, and the side of the protective shell 710 close to the telescopic rod 2 is fixedly connected thereto, a first sliding block 706 is provided on the outer wall of the sliding rod 705, the first sliding block 706 is slidably connected to the sliding rod 705, an elastic plate 707 is fixedly connected to the left side of the inner wall of the first sliding block 706, the inner wall of the first sliding block 706 contacts the second sliding block 708, the bottom of the second sliding block 708 is fixedly connected to a connecting plate 709, the sliding rod 705 passes through the second sliding block 708, and is fixedly connected to the connecting plate 709. The sliding connection is provided with a first sliding block 706 and a second sliding block 708 so that the first sliding block 706 does not interfere with the second sliding block 708 when sliding downward, and when the second sliding block 708 slides to the bottom, the elastic plate 707 will be stuck in the notch of the protective shell 710, resulting in the second sliding block 708 having to rotate the position of the elastic plate 707 when it wants to rise, so that the second sliding block 708 can fix the elastic plate 707 and bend it before it can move upward. The outer walls of the two groups of sliders 803 are fixedly connected with a downward pressure rod 702, and the bottom of the downward pressure rod 702 is fixedly connected with two groups of pressing rods 703, and the sides of the two groups of pressing rods 703 close to each other are fixedly connected with a pedal 704, and the bottom of the pedal 704 is fixedly connected with a connecting plate 709.

[0037] The working principle of this embodiment is as follows: when the staff needs to adjust the multifunctional teaching board for English ideological and political education, the staff presses the pedal 704 to press downward. At this time, the pressing rod 703 moves downward synchronously under the drive of the pedal 704, and the downward movement of the pressing rod 703 drives the pressing rod 702 to move downward, causing the first spring 6 to start to compress. When the pedal 704 moves downward, it also drives the connecting plate 709 to move downward. The connecting plate 709 drives the second sliding block 708 to move downward, causing the first sliding block 706 to lose its supporting force and slide downward synchronously on the sliding rod 705, causing the elastic plate 707 to not contact the inner wall of the protective shell 710. When the first sliding block 706 slides to the gap of the protective shell 710, the elastic plate 707 is unfolded by its own resilience, causing the first sliding block 706 to stop moving downward, and the first sliding block 706 will also rotate while sliding, so that the elastic plate 707 rotates toward the gap, causing the second sliding block 708 to rotate without being affected by the first sliding block 706. At this time, the pressure on the pedal 704 is stopped, causing the first spring 6 to lose the downward pressure and start to rebound. At this time, the second sliding block 708 is restricted by the elastic plate 707 and the first sliding block 706 and cannot move upward, thereby limiting the upward movement of the pedal 704 and fixing it.

[0038] Example 2: Please refer to Figure 5-Figure 7 On the basis of the first embodiment, the present invention provides a technical solution: a rotating mechanism 8, the rotating mechanism 8 includes two groups of fixed blocks 801, the sides of the two groups of fixed blocks 801 close to each other are fixedly connected to the electronic board 4, the inner walls of the two groups of fixed blocks 801 are rotatably connected to the rotating blocks 808 through the rotating shafts, the bottoms of the two groups of rotating blocks 808 are respectively fixedly connected to the first pull ropes 802, the sides of the two groups of first pull ropes 802 away from the rotating blocks 808 are respectively fixedly connected to the sliders 803, the sides of the two groups of fixed blocks 801 away from each other are provided with rotating wheels 806, the left and right sides of the top of the electronic board 4 are fixedly connected to the suspension rods 805, the bottoms of the two groups of suspension rods 805 are respectively fixedly connected to the protective shells 804, the inner walls of the two groups of protective shells 804 are rotatably connected to the rotating rods 811 through the rotating shafts, and the two groups The outer wall of the rotating rod 811 is fixedly connected with three groups of pull rods 807, and the two groups of rotating blocks 808 are rotatably connected with the tilting plate 809 on the side away from the electronic board 4 through the rotating shaft, and the bottom of the tilting plate 809 is rotatably connected with the clamp 810 on the side away from the rotating block 808 through the rotating shaft. The two groups of rotating rods 811 are respectively fixedly connected with the rotating wheels 806 on the side close to the writing board 3. The two groups of clamps 810 are in contact with the pull rods 807 close to the electronic board 4. By setting the clamp 810, the pull rods 807 in different positions can be clamped, so that when the staff is in use, they can achieve different angles of rotation by clamping the pull rods 807 in different positions, resulting in different angles being suitable for different staff. The bottoms of the two groups of sliders 803 are respectively fixedly connected with the first spring 6.

[0039] The working principle of this embodiment is as follows: when the slider 803 slides downward, it drives the first pull rope 802 to move in the direction close to the telescopic rod 2. At this time, the first pull rope 802 drives the rotating block 808 to rotate counterclockwise, and the rotation of the rotating block 808 drives the inclined plate 809 to move upward. At this time, the clamp 810 fixed on the inclined plate 809 moves upward synchronously, so that the clamp 810 drives the pull rod 807 to rotate upward. At this time, the pull rod 807 drives the rotating rod 811 to rotate, and then the rotating rod 811 drives the rotating wheel 806 to rotate synchronously, thereby completing the work.

[0040] Example 3: Please refer to Figure 8-Figure 9On the basis of the first and second embodiments, the present invention provides a technical solution: an adjustment mechanism 9, the adjustment mechanism 9 includes a curved rod 901, the curved rod 901 is fixed to the rotating wheel 806 on one side close to the telescopic rod 2, an arc groove 902 is provided on the outer wall of the curved rod 901, a rotating shaft is slidably connected to the groove wall of the arc groove 902, and a rotating disk 903 and a writing board 3 are respectively fixedly connected on both sides of the rotating shaft, and three groups of curved grooves 907 are provided on the outer wall of the rotating disk 903, and the three groups of curved grooves The groove wall 907 is rotatably connected to the swing plate 908 through the gear column 909. The three sets of gear columns 909 are rotatably connected to the curved groove 907 through the bearing on the side close to the writing board 3. The bottom of the three sets of curved grooves 907 is fixedly connected to the second bottom plate 911. The top of the three sets of second bottom plates 911 is rotatably connected to the block 910 through the rotating shaft. The three sets of blocks 910 are fixedly connected to the second spring 912 on the side away from the swing plate 908. The three sets of blocks 910 are meshed with the gear column 909. The three groups of second springs 912 are all fixedly connected to the wall of the curved groove 907. The rotating disk 903 is provided with three groups of rolling grooves 904 on one side close to the electronic board 4. The walls of the three groups of rolling grooves 904 are all in contact with rolling balls 906. Baffles 905 are provided at the middle ends of the three groups of rolling grooves 904. The three groups of baffles 905 are all fixedly connected to the wall of the rolling groove 904. The outer walls of the three groups of rolling balls 906 are fixedly connected to the second pull ropes 913. The rolling balls 906 are provided to pull the pull rod 807. The control is such that the block 910 is controlled by moving the rolling ball 906, so that the rolling ball 906 can release the control of the swinging plate 908 when moving. In this way, it is possible to judge whether the rotating disk 903 is moving according to the rotation state and the stop state of the rolling ball 906. The three groups of second pull ropes 913 pass through the arc groove 902 and the curved groove 907, and are fixedly connected to the block 910. The adjustment mechanism 9 is arranged in two groups, which are symmetrically arranged with the middle of the electronic board 4 as the center.

[0041] The working principle of this embodiment is as follows: when the rotating wheel 806 drives the curved rod 901 to rotate, the curved rod 901 rotates upward, causing the rotating shaft to start sliding in the arc groove 902, causing one of the three groups of rolling balls 906 on the rotating disk 903 to start rolling forward, causing the rolling balls 906 to drive the second pull rope 913 to move during the rolling process. When the second pull rope 913 is pulled, it will drive the block 910 to gradually move away from the gear column 909, causing the second spring 912 to start to be continuously compressed, causing the swing plate 908 to lose its restriction and start to rotate. At this time, due to the rotating disk 9 When the rotating disk 903 is still sliding in the arc groove 902, the swing plate 908 starts to rotate, causing the rotating disk 903 to start to rotate at an accelerated speed. At this time, the writing board 3, which was originally in a horizontal state with the curved rod 901, begins to tend to a vertical state. When the rotating disk 903 is in a stopped state after the rotation is completed, the rolling ball 906 will return to its original position due to inertia, and then drive the second pull rope 913 to move, so that the second pull rope 913 pulls the block 910 to rotate again. At this time, the second spring 912 starts to rebound and increase the thrust, so that the block 910 is meshed with the gear column 909 again, thereby completing the work.
