DETAILED DESCRIPTION

[0026] The present application is further described in detail below in conjunction with the accompanying drawings.

[0027] Embodiment 1:

[0028] Reference Figure 1 and Figure 2 , the embodiment of the present application discloses a multimedia teaching device for network education. A mobile base 1, a spherical wheel is installed at the bottom of the mobile base 1;

[0029] The limit member 2 includes a pull frame 3 slidably connected to the mobile base 1, pull blocks 4 are connected and fixed at both ends of the pull frame 3, a limit spring 5 is connected and fixed on the top surface of the pull block 4, a suction cup 6 is arranged under the pull block 4, and the other end of the limit spring 5 is connected and fixed to the inner wall of the mobile base 1.

[0030] The design of the limit member 2 allows the pull block 4 to be released after the teaching display screen 10 needs to be moved. At this time, the limit spring 5 will drive the suction cup 6 set under the pull block 4 to be adsorbed to the ground or the desktop, so that the mobile base 1 can be limited quickly, avoiding the problem of the prior art that multiple universal wheels need to be fixed one by one, and it is relatively easy to use.

[0031] A vent frame 7 is connected and fixed to the top surface of the suction cup 6 , a sealing plug 8 is slidably connected inside the vent frame 7 , and the sealing plug 8 is connected and fixed to the pulling block 4 .

[0032] When the movable base 1 needs to be moved, the pull block 4 can be pulled, thereby driving the pull block 4 to pull the sealing plug 8 upward. At this time, the sealing plug 8 moves upward to expose the air holes at the bottom of the air permeable frame 7, so that the negative pressure inside the suction cup 6 disappears, and the movable base 1 can be moved.

[0033] Embodiment 2:

[0034] Reference Figure 3 The embodiment of the present application discloses a multimedia teaching device for network education. A teaching display screen 10 is connected to a mobile base 1 through an adjustment mechanism 9, and the adjustment mechanism 9 includes a mounting frame 11 connected and fixed to the mobile base 1 and the teaching display screen 10, and a connecting rod 12 is rotatably connected to the inner ends of the two mounting frames 11.

[0035] The adjustment mechanism 9 also includes a snap-in groove 13 opened inside the installation frame 11, and a snap-in frame 14 is snap-fitted inside the snap-in groove 13. A reset spring 15 is connected and fixed to the end of the snap-in frame 14. The snap-in frame 14 is slidably connected to the installation frame 11 and the connecting rod 12, and the other end of the reset spring 15 is connected and fixed to the installation frame 11.

[0036] The adjustment mechanism 9 further includes two friction blocks 16 slidably connected to the clamping frame 14 . Abutment springs 17 are connected and fixed to the inner walls of the two friction blocks 16 . The friction blocks 16 are frictionally matched with the inner wall of the installation frame 11 .

[0037] The design of the adjustment mechanism 9 allows the clamping frame 14 to be pressed when the angle of the teaching display screen 10 needs to be adjusted. At this time, the clamping frame 14 compresses the abutment spring 17 and slides out from the inside of the clamping groove 13. At this time, the teaching display screen 10 can be rotated, and the abutment spring 17 will press the friction block 16 to rub against the inner wall of the clamping frame 14. In this way, the teaching display screen 10 can be prevented from losing its limit and rotating quickly, and can be adjusted slowly and at will. After adjustment, the abutment spring 17 drives the clamping frame 14 to clamp with the clamping groove 13, so that the teaching display screen 10 is limited.

[0038] The implementation principle of a multimedia teaching device for network education in the embodiment of the present application is as follows: after the teaching display screen 10 needs to be moved, the pull block 4 is released, and the limit spring 5 will drive the suction cup 6 set under the pull block 4 to be adsorbed to the ground or the desktop, so that the limit of the mobile base 1 can be quickly achieved. When the mobile base 1 needs to be moved, the pull block 4 can be pulled at this time, thereby driving the pull block 4 to pull the sealing plug 8 upward. At this time, the upward movement of the sealing plug 8 will expose the air hole at the bottom of the air-permeable frame 7, so that the negative pressure inside the suction cup 6 disappears, and the mobile base 1 can be moved. When the angle of the teaching display screen 10 needs to be adjusted, the card frame 14 is pressed. At this time, the card frame 14 compresses the abutment spring 17 and slides out from the inside of the card slot 13. At this time, the teaching display screen 10 can be rotated, and the abutment spring 17 will press the friction block 16 to rub against the inner wall of the card frame 14, so that the teaching display screen 10 can be prevented from losing the limit and rotating quickly, and can be adjusted slowly and arbitrarily. After adjustment, the abutment spring 17 drives the card frame 14 to be engaged with the card slot 13, so that the teaching display screen 10 is limited.
