[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Reference Figure 1-7The present invention provides an embodiment of a mobile learning smart terminal support, comprising a base 1 and a fixed base 3. The base 1 has a sliding groove 23 inside, and a slider 24 is slidably connected inside the sliding groove 23. Both the sliding groove 23 and the slider 24 are T-shaped structures. The top of the slider 24 is fixedly connected to the fixed base 3, which is U-shaped. A frame 4 is rotatably connected inside the fixed base 3, which is U-shaped. The friction between the outer side wall of the frame 4 and the inner side wall of the fixed base 3 is sufficient to prevent the frame 4 from rotating due to its own weight in a vertical state.

[0040] A fixed rod 5 is rotatably connected inside the frame 4. The fixed rod 5 is a hollow structure with an opening at the top. A connecting rod 6 is slidably connected inside the fixed rod 5. A connecting rod 18 is fixedly connected to one end of the connecting rod 6. The connecting rod 18 is made of metal directional flexible hose. By bending the connecting rod 18, the angle of the back plate 8 can be adjusted so that the back plate 8 can adapt to the needs of different environments. The back plate 8 is fixedly connected to one end of the connecting rod 18. Fixed plates 21 are fixedly connected to both sides of the rear end of the back plate 8. A double-ended screw 20 is rotatably connected inside the fixed plate 21. A slot 22 is opened inside the back plate 8. Two clamping plates 7 are slidably connected inside the slot 22. A side plate 19 is fixedly connected to one end of the two clamping plates 7. The two side plates 19 penetrate the inner side wall of the slot 22. Both side plates 19 are threaded to the outer side of the middle of the double-ended screw 20.

[0041] The double-ended screw 20 is rotated by hand, which allows the side plate 19 to move to both sides. When the side plate 19 moves, it will cause the clamping plate 7 to slide inside the slot 22. Then, the learning terminal is placed on the front end of the back plate 8, and the double-ended screw 20 is rotated in the opposite direction, so that the side plate 19 can push the clamping plate 7 closer to each other to clamp the learning terminal on the back plate 8, thereby fixing the learning terminal to the back plate 8.

[0042] Multiple limiting grooves 12 are provided on both sides of the bottom end of the fixed rod 5. Mounting grooves 13 are provided on both sides of the top of the inner side of the frame 4. A spring 16 is fixedly connected to the inner wall of the mounting groove 13. One end of the spring 16 is fixedly connected to a limiting block 11. One end of the limiting block 11 is inserted into the limiting groove 12. Both the limiting groove 12 and the limiting block 11 are designed as arc-shaped structures, so that when the fixed rod 5 rotates, the arc-shaped limiting groove 12 will squeeze the limiting block 11, forcing the limiting block 11 to retract into the mounting groove 13, thereby enabling the fixed rod 5 to rotate. A fixing pin 17 is threadedly connected to the top of the fixed rod 5.

[0043] Rotate frame 4 backward to stand it up, then rotate fixing rod 5 so that fixing rod 5 and frame 4 are on the same vertical line. At this time, spring 16 will push limiting block 11 into limiting groove 12 to fix fixing rod 5. Then rotate fixing pin 17 and pull connecting rod 6 upward to extend connecting rod 6 from inside fixing rod 5. Then rotate fixing pin 17 in the opposite direction to let fixing pin 17 enter fixing rod 5 to fix connecting rod 6, thereby raising the height of back plate 8 so that the bracket can be used outdoors. Conversely, rotate frame 4 forward to make frame 4 fit tightly against base 1, then rotate fixing rod 5 in the same direction so that fixing rod 5 is perpendicular to frame 4. Use spring 16 to push limiting block 11 into limiting groove 12 for fixation, and retract connecting rod 6 into fixing rod 5 to lower the height of back plate 8 so that the bracket can be used on a table.

[0044] Furthermore, when the top of the frame 4 is parallel to the top of the base 1, the fixing rod 5 is rotated backward so that the fixing rod 5 enters the frame 4. At this time, the spring 16 pushes the limiting block 11 into the limiting groove 12 to fix the fixing rod 5, so that the fixing rod 5 is close to the base 1, which can reduce the space occupied by the bracket, thereby making it easier for users to carry and move.

[0045] A groove 14 is provided on the inner side wall of the mounting groove 13. A protrusion 15 is slidably connected inside the groove 14. One end of the protrusion 15 is fixedly connected to one side of the limiting block 11. When the spring 16 pushes the limiting block 11 to move, the limiting block 11 will drive the protrusion 15 to slide inside the groove 14. The protrusion 15 can restrict the movement of the limiting block 11, so that the limiting block 11 can only move back and forth inside the mounting groove 13.

[0046] The top of the slider 24 has two fixing holes 9 on both sides. Bolts 2 are threaded into the two fixing holes 9. One end of each bolt 2 passes through the top wall of the slide groove 23. After the frame 4 is erected, the bolts 2 can be rotated by hand to remove them from the fixing holes 9. Then, the fixing seat 3 is pushed to one side to make the slider 24 slide inside the slide groove 23. When the slider 24 slides to the middle of the slide groove 23, the bolts 2 can be inserted through the slide groove 23 and tightened into the fixing holes 9 to fix the slider 24. This adjusts the center of gravity of the base 1 and prevents the base 1 from being unstable when placed on the ground due to the excessive height of the back plate 8.

[0047] The base 1 has four mounting compartments 25 on its outer side. Each mounting compartment 25 has a counterweight 10 inserted inside. Inserting the counterweight 10 into the mounting compartment 25 increases the weight of the base 1, thus preventing the back plate 8 from being too heavy for the learning terminal after it is fixed, which would cause the support to tip over.

[0048] Working principle: Rotate the double-ended lead screw 20 to make the clamping plate 7 slide inside the slot 22. Then, place the learning terminal on the front end of the back plate 8. Rotate the double-ended lead screw 20 in the opposite direction to make the clamping plates 7 move closer together to clamp the learning terminal on the back plate 8, thereby fixing the learning terminal to the back plate 8. Insert the bolt 2 through the slide groove 23 into the fixing hole 9 and tighten it to fix the slider 24. Adjust the center of gravity of the base 1 and make the fixing rod 5 and the frame 4 on the same vertical line. Then, the spring 16 pushes the limiting block 11 into the limiting groove 12 to fix the fixing rod 5. Pull the connecting rod 6 upward to move the connecting rod 6 from the fixed position. The fixed rod 5 extends outward, and the fixing pin 17 is rotated to fix the connecting rod 6, thereby raising the height of the back plate 8 so that the bracket can be used outdoors. Conversely, the bolt 2 is removed from the fixing hole 9, and the fixing seat 3 is pushed to make the slider 24 slide to one end of the slide groove 23. The slider 24 is fixed again with the bolt 2. The frame 4 is rotated forward so that the frame 4 is close to the base 1 and the fixing rod 5 is perpendicular to the frame 4. At the same time, the fixing rod 5 is fixed again with the spring 16, the limiting block 11 and the limiting groove 12. Meanwhile, the connecting rod 6 is retracted into the fixed rod 5 to lower the height of the back plate 8 so that the bracket can be used on a table.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
