[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1-Figure 4The utility model provides a technical solution: an adjustable English teaching card display device, comprising a box body 1, a magnetic ring 2 is provided on the surface of the box body 1, a base 3 is installed under the box body 1, a window 4 is opened on the box body 1, a rotating wheel 5 is provided in the box body 1, a strip card 6 is provided on the surface of the rotating wheel 5, the strip card 6 is in a ring structure connected end to end, and 26 letters are drawn on the surface of the strip card 6, a horizontal shaft 7 is installed on the rotating wheel 5, a first bevel gear 8 is fixed on the surface of the horizontal shaft 7, a second bevel gear 9 is connected to the outside of the first bevel gear 8, a driving rod 10 is installed on the second bevel gear 9, a sleeve rod 11 is installed on the surface of the box body 1, a knob 12 is installed on the sleeve rod 11, and a reset spring 14 is installed at one end of the knob 12 located inside the sleeve rod 11.

[0020] The magnetic rings 2 are embedded in the surface of the box body 1 , and the magnetic rings 2 are symmetrically distributed on the surface of the box body 1 , so that the box body 1 can be conveniently spliced ​​and assembled on the left and right sides through the magnetic rings 2 on the left and right sides.

[0021] The rotating wheel 5 is fixedly connected to the transverse shaft 7 , and the transverse shaft 7 is rotationally connected to the box body 1 . When the transverse shaft 7 rotates in the box body 1 , the transverse shaft 7 can drive the rotating wheel 5 to rotate synchronously in the box body 1 .

[0022] The driving rod 10 is rotationally connected to the box body 1. The end of the driving rod 10 away from the second bevel gear 9 is a square rod structure. A docking hole 13 is provided on the knob 12. One end of the driving rod 10 fits with the docking hole 13, making it convenient for the knob 12 to dock with the driving rod 10 through the docking hole 13. Turning the knob 12 can drive the driving rod 10 to rotate synchronously.

[0023] The knob 12 forms a telescopic structure with the sleeve rod 11 through the return spring 14. The knob 12 is rotatably connected to the sleeve rod 11, which is conducive to the return spring 14 pushing the knob 12 to perform telescopic movement in the sleeve rod 11, and at the same time facilitates the knob 12 to rotate in the sleeve rod 11.

[0024] Working principle: When using this device, multiple box bodies 1 are spliced ​​and placed left and right through the magnetic rings 2 on the surface. When a word needs to be displayed, just turn the knob 12 on the box body 1 from left to right. The specific operation is: press the knob 12 to retract it into the sleeve rod 11 until the knob 12 docks with the drive rod 10 through the docking hole 13, and then turn the knob 12. The knob 12 drives the drive rod 10 to rotate, and the drive rod 10 drives the horizontal shaft 7 to rotate through the second bevel gear 9 and the first bevel gear 8, so that the horizontal shaft 7 drives the rotating wheel 5 and the rotating wheel 5 The strip card 6 on the surface rotates, which is conducive to the switching display of the letters on the surface of the strip card 6 in the window 4 on the surface of the box body 1, and the letters displayed on the adsorbed and spliced ​​box body 1 can be combined into words from left to right for display. After the knob 12 is turned, the pressed knob 12 is released. At this time, the return spring 14 pushes the knob 12 to extend out of the sleeve rod 11 until the knob 12 is disconnected from the drive rod 10. Therefore, when the knob 12 is accidentally touched, it will not cause the wheel 5 to drive the strip card 6 to rotate out of position, thereby preventing the correct display of the word from being affected.

[0025] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
