Specific implementation

[0021] The utility model makes further detailed explanation below:

[0022] As Figures 1 to 5 The utility model provides a video playing device for course teaching, including base 1 and display screen 2, and the top of base 1 is provided with mounting groove 3, and the inside fixed mounting of mounting groove 3 has protective assembly 4, and the left and right sides of base 1 movably install the stable assembly 5 of front -back symmetry, and the bottom of base 1 movably installs universal wheel 6, and protective assembly 4 includes lower installation shell 41 and upper protective shell 42, lower installation shell 41 is fixedly installed in the inside of mounting groove 3, and upper protective shell 42 is fixedly installed on the top of base 1, and lower installation shell 41 and upper protective shell 42 inside movably install the lifting screw rod 43 of front -back symmetry, and the lower fixed mounting of the outside of lifting screw rod 43 has worm wheel 44, and the inside of lower installation shell 41 is movably installed with the worm 46 of front and back, and the inside fixed connection of worm 46 has transmission shaft 45, and the front fixed mounting of worm wheel 44 has hand wheel one 47 located outside base 1, and the outside of lifting screw rod 43 movably installs sliding block 48, and display screen 2 is fixedly installed in the inside of sliding block 48.

[0023] by rotating hand wheel one 47 and drive worm 46 rotation, by worm wheel 44 and worm 46 meshing to synchronous drive worm wheel 44 outside lifting screw rod 43 rotation, by worm wheel 44 drive the lifting screw rod 43 of front -back symmetry setting in upper protective shell 42 rotation to drive sliding block 48 drive display screen 2 and go up along the inside of upper protective shell 42, to stretch out from the top of upper protective shell 42 when using, when not using, income upper protective shell 42 to lower the gravity center of display screen 2 while providing external protection.

[0024] As Figure 4 shown, the left and right sides of the base 1 are provided with receiving grooves 11, and the front and back sides of the receiving grooves 11 are provided with mounting holes 12. The stabilizing assembly 5 comprises a rotating shaft 51 movably mounted in the mounting hole 12. The rotating shaft 51 is fixedly provided with a support rod 52. The support rod 52 is internally provided with a threaded hole 53. The threaded hole 53 is movably provided with a supporting screw 54. The bottom of the supporting screw 54 is movably connected with a foot pad 55. The top of the supporting screw 54 is fixedly provided with a hand wheel 56.

[0025] By rotating the support rod 52 on the front and back sides of the base 1 outward along the receiving groove 11, the rotating shaft 51 is driven by the support rod 52 to rotate outward along the mounting hole 12. Then, the supporting screw 54 is driven by rotating the hand wheel 56 to move downward in the threaded hole 53, so that the foot pad 55 contacts the ground to provide support for the base 1. By independently adjusting the hand wheel 56 on the four corners of the base 1, stable support for the base 1 can be ensured.

[0026] As Figure 2 and Figure 3 shown, the upper protective shell 42 is arranged above the lower mounting shell 41.

[0027] By arranging the upper protective shell 42 above the lower mounting shell 41, the lifting screw 43 in the lower mounting shell 41 and the upper protective shell 42 can be normally driven to rotate to drive the display screen 2 to perform lifting operation.

[0028] As Figure 3 shown, the worm gear 44 and the worm 46 are arranged inside the lower mounting shell 41.

[0029] By arranging the worm gear 44 and the worm 46 inside the lower mounting shell 41, the worm 46 is driven by the transmission shaft 45 connected between the worm gears 44 to rotate synchronously, thereby driving the worm gear 44 meshed therewith to rotate, while preventing the lifting screw 43 from rotating, so as to ensure the stability of the lifting adjustment.

[0030] As Figure 3 shown, the top of the display screen 2 is fixedly provided with a top plate 49 matched with the upper protective shell 42.

[0031] After the display screen 2 is received in the upper protective shell 42, the top plate 49 can close the opening at the top of the upper protective shell 42.

[0032] As Figure 4 shown, the threaded hole 53 is arranged on the side of the support rod 52 away from the rotating shaft 51.

[0033] By arranging the threaded hole 53 on the side away from the rotating shaft 51, the support range of the foot pad 55 on the base 1 can be increased by opening the support rod 52.

[0034] As Figure 5 The top of the base 1 is fixedly installed with a battery box 7.

[0035] The display screen 2 can be powered by the battery box 7, and the ball teaching video can be played for learning by operating the display screen 2.

[0036] The working principle of the video playing device for course teaching will be described below.

[0037] As Figures 1 to 5 When not in use, the display screen 2 is accommodated in the inside of the upper protective shell 42, which can play a protective role and reduce the center of gravity of the display screen 2, facilitating the movement of the base 1. When in use, the base 1 is moved to a designated position, the support rods 52 on the front and rear sides of the base 1 are rotated outward along the receiving grooves 11, the support rods 52 drive the rotating shafts 51 to rotate outward along the mounting holes 12, the hand wheel two 56 is rotated to drive the support screw 54 to move downward in the threaded hole 53, the foot pad 55 contacts the ground to provide support for the base 1, the hand wheel one 47 on the front side of the base 1 is rotated to drive the worm 46 to rotate, the transmission shaft 45 is connected between the worm gears 44 for synchronous transmission, thereby synchronously driving the worm gears 44 outside the lifting screw 43 to rotate, the lifting screw 43 symmetrically arranged in the upper protective shell 42 is driven to rotate by the worm gears 44 to drive the sliding block 48 to drive the display screen 2 to move upward out of the inside of the upper protective shell 42, the display screen 2 is connected with the battery box 7 to play the ball teaching video by operating the display screen 2 for students to learn.

[0038] The above is a detailed description of the present application, but some modifications or improvements can be made on the basis of the present application, which is obvious to those skilled in the art. Therefore, without departing from the spirit of the present application, the modifications or improvements are within the scope of the present application.
