Example

[0022] See also Figure 1-Figure 6 , a teaching platform shown in the figure includes a teaching platform display screen 102 arranged on a fixed plate 101, and also includes a protection mechanism arranged on the fixed plate 101 for protecting the display screen 102 when not in use;

[0023] The protective mechanism includes a mounting plate 201 fixedly connected to the fixing plate 101, a U-shaped telescopic protective cover 202 is provided on one side of the mounting plate 201 close to the display screen 102, a push plate 203 is fixedly connected to the other end of the U-shaped telescopic protective cover 202, the push plate 203 is also U-shaped, a handle 204 is provided on the side of the push plate 203 away from the display screen 102, a contraction mechanism for contracting the U-shaped telescopic protective cover 202 is provided on the mounting plate 201, and a limiting mechanism for limiting the telescopic protective cover 202 is provided on the fixing plate 101;

[0024] It should be noted here that: through the setting of the protective mechanism, under the limiting action of the limiting mechanism, the stretched U-shaped telescopic protective cover 202 is limited and fixed, so that the unused display screen 102 is protected by the shielding protection of the U-shaped telescopic protective cover 202, thereby reducing the risk of dust falling and accidental damage caused by human touch, and further improving the safety protection of the display screen 102 when not in use.

[0025] See also Figure 2 and Figure 3, there are two retracting mechanisms shown in the figure, and the two retracting mechanisms are symmetrically arranged. The retracting mechanisms include two symmetrically arranged connecting plates 301 fixedly connected to the side of the mounting plate 201 away from the display screen 102, a rotating rod 302 is rotatably connected between the two connecting plates 301, a winding disk 303 is fixedly connected to the side wall of the rotating rod 302, a pull rope 304 is wound around the side wall of the winding disk 303, a telescopic plate 305 is fixedly connected to the side wall of the pushing plate 203, and one end of the pull rope 304 is connected to the telescopic plate 305;

[0026] It should be noted here that: by setting the retracting mechanism, when the display screen 102 is in use, the U-shaped retractable protective cover 202 is driven to retract to the top of the display screen 102 .

[0027] See also Figure 2 and Figure 3 , one end of the rotating rod 302 shown in the figure passes through the connecting plate 301 and is fixedly connected to a circular plate 306, a torsion spring 307 is sleeved on the side wall of the rotating rod 302, and both ends of the torsion spring 307 are respectively connected to the circular plate 306 and the connecting plate 301;

[0028] It should be noted here that: the torsion spring 307 is provided to facilitate the U-shaped telescopic protective sleeve 202 to be contracted.

[0029] Working principle: When the display screen 102 for the teaching platform is not in use, the handle 204 is pulled to drive the push plate 203 to slide around the display screen 102, and the U-shaped telescopic protective cover 202 is further stretched, so that the U-shaped telescopic protective cover 202 is sleeved on the side of the display screen 102, and under the action of the limiting mechanism, the stretched U-shaped telescopic protective cover 202 is limited and fixed, so that the unused display screen 102 is protected by the shielding protection of the U-shaped telescopic protective cover 202, thereby reducing the risk of dust falling and damage caused by accidental human contact, and further improving the safety protection of the display screen 102 when not in use;

[0030] In the process of stretching the U-shaped telescopic protective cover 202, the pull rope 304 on the winding disk 303 is pulled, and in the process of the pull rope 304 being pulled, the rotating rod 302 is driven to rotate, and in the process of the rotating rod 302 rotating, the torsion spring 307 is deformed by force to form an elastic force;

[0031] When the display screen 102 needs to be used, the limit on the push plate 203 is released. At this time, under the elastic action of the torsion spring 307, the U-shaped telescopic protective cover 202 is driven to retract, thereby removing the obstruction of the display screen 102, so that the display screen 102 is exposed to the outside and can be used normally, and the U-shaped telescopic protective cover 202 is retracted to the top of the display screen 102, so as not to affect the use and viewing of the display screen 102. Example

[0032] See also Figure 4-Figure 6 , this embodiment further explains Example 1, the limiting mechanism in the figure includes an operating plate 408 fixedly connected to the fixed plate 101, the operating plate 408 is located below the display screen 102, an operating hole 401 is provided on the side of the operating plate 408 close to the display screen 102, a limiting hole 402 is provided on the inner wall of the operating hole 401, a mounting hole 403 is provided on the side of the push plate 203 close to the operating plate 408, a sliding plate 404 is connected to the mounting hole 403 through an extrusion component, a connecting hole is provided on the side wall of the sliding plate 404, the connecting hole is connected to the limiting plate 405 through a first spring 407, and a slope 406 is provided on the side of the limiting plate 405 close to the operating plate 408;

[0033] It should be noted here that: through the setting of the limiting mechanism, in the process of the pushing plate 203 driving the U-shaped telescopic protective cover 202 to move close to the operating plate 408, when the limiting plate 405 on the sliding plate 404 abuts against the operating plate 408, under the interaction force of the inclined surface 406 and the guiding action of the connecting hole, the limiting plate 405 will be pushed to retract into the connecting hole. As the pushing plate 203 is continuously pushed, when the limiting plate 405 is matched with the limiting hole 402, under the elastic action of the first spring 407, the limiting plate 405 will be pushed into the limiting hole 402 and abut against the bottom wall of the limiting hole 402, so that the pushing plate 203 is limited and fixed by the abutting action of the limiting plate 405, and the U-shaped telescopic protective cover 202 is further limited and fixed, thereby ensuring the stability of the U-shaped telescopic protective cover 202 in shielding and protecting the display screen 102.

[0034] See also Figure 6 The extrusion assembly shown in the figure includes an extrusion rod 501 fixedly connected between two inner walls of the mounting hole 403, a sliding plate 404 slides on the side wall of the extrusion rod 501, and a second spring 502 is sleeved on the side wall of the extrusion rod 501, and two ends of the second spring 502 are respectively connected to the sliding plate 404 and the inner wall of the mounting hole 403;

[0035] It should be noted here that: through the setting of the extrusion component, the sliding plate 404 is always against the inner wall of the installation hole 403, so as to facilitate the insertion of the limit plate 405 into the limit hole 402. At the same time, the extrusion component also resets the limit plate 405 after being pulled.

[0036] It is worth noting that the elastic force of the second spring 502 is greater than the elastic force of the first spring 407 .

[0037] See also Figure 6The push plate 203 shown in the figure is provided with a driving assembly for driving the limit plate 405, and the driving assembly includes a driving hole 601 opened on the side of the push plate 203 away from the display screen 102, the driving hole 601 is communicated with the mounting hole 403, a driving plate 602 is slidably connected in the driving hole 601, and one end of the driving plate 602 is connected to the sliding plate 404;

[0038] It should be noted here that: through the setting of the driving component, in the process of pulling the driving plate 602, the limit plate 405 on the sliding plate 404 will be driven to move out of the limit hole 402, thereby releasing the connection limit between the push plate 203 and the operating plate 408, and further releasing the limit on the U-shaped telescopic protective cover 202.

[0039] It is worth noting that the length of the operating hole 401 meets the movement requirement of the sliding plate 404 .
