Description

Technical Field

[0001] The present invention relates to the technical field of English teaching, and in particular to an English language teaching device with a reading mark structure. Background Art

[0002] English is the most popular language nowadays, and its teaching is achieved through teachers’ writing and reading explanations.

[0003] When teaching English, teachers usually write English sentences on the blackboard and teach by reading and explaining them. However, due to limited teaching time each time or part of the written English sentences are suitable for the teaching and explanation of the next course, the written English sentences are not completely read and explained. The English sentences written on the ordinary teaching blackboard need to be erased after each class to facilitate subsequent teaching by other teachers, resulting in the inability to retain the English sentences that have not been completely read and explained. They need to be recalled and written again during the next teaching, which affects teaching efficiency. Even if the English sentences written on the ordinary teaching blackboard are required to be retained, it is easy for some uninformed students or other people to erase the English sentences written on the ordinary teaching blackboard during cleaning, which affects the subsequent English reading and explanation.

In order to facilitate faster finding of the position that was not read and explained last time when reading and explaining next time, the teacher can slide the reading mark block 306 up and down along the reciprocating slide 305 before re-limiting the teaching board 3 into a separate storage installation slot, so that the marking arrow B307 set on the front end surface of the reading mark block 306 points to the position of the English teaching language sentence that has not been read and explained, thereby realizing reading marking, so that the position area that has not been read and explained next time can be quickly found.

[0046] The specific usage and function of this embodiment are as follows:

[0047] The main body block 1 of the present invention is fixed on the wall of the classroom by the cooperation of the mounting holes 201 opened on the mounting base 2 and the bolts;

[0048] Before the teacher teaches English, he can insert a set of teaching boards 3 into the installation slot 101. Through the magnetic attraction of the embedded iron block 308 and the magnet adsorption block 104, the set of teaching boards 3 are limited and inserted into the installation slot 101, completing the installation and limitation of the set of teaching boards 3. When the teacher teaches English, since a blackboard 301 is embedded in the front surface of the teaching board 3, the teacher can write corresponding English teaching language sentences on the blackboard 301 for teaching;

[0049] Furthermore, the bottom surface of the inner end and the left side of the top surface of the mounting groove 101 of the present invention are both provided with a plug-in matching groove B107 with an inclined groove structure. Through the setting of the plug-in matching groove B107, when the teaching board 3 is inserted into the mounting groove 101, the limit card column 309 protruding from the spring receiving groove 3011 will cooperate with the plug-in matching groove B107 so that it will not hinder the insertion and installation operation of the teaching board 3. When the teaching board 3 is inserted into the mounting groove 101, the limit column 102 will be inserted into the The limiting hole 302 is in contact with the ball bearing 3010, and because the size of the mounting groove 101 is larger than that of the teaching board 3, the side end surface of the teaching board 3 will not contact the inner side surface of the mounting groove 101. Therefore, when the teaching board 3 needs to be removed from the mounting groove 101, the teaching board 3 can be pulled by grasping the gripping portion formed by the through gripping opening 303 and the gripping groove 304 on the teaching board 3 through the through groove 103, thereby removing the teaching board 3 from the mounting groove 101 smoothly and unobstructed.

[0050] When the English teaching language sentences written on the blackboard 301 have not been read and explained, but the corresponding teaching time has arrived or the remaining unread and explained language sentences need to wait until the corresponding English teaching part to be read and explained again, the teacher can choose to re-limit the teaching board 3 with the English teaching language sentences written on the blackboard 301 and store it in a separate storage installation slot;

[0051] A reciprocating slide 305 is provided on the right side of the front end surface of the blackboard 301 of the present invention, and a reading mark block 306 is slidably installed in the reciprocating slide 305. For example, in order to facilitate faster locating of the position where the last explanation was not read when reading and explaining next time, the teacher can slide the reading mark block 306 up and down along the reciprocating slide 305 before re-limiting and storing the teaching board 3 into the separate storage installation slot, so that the marking arrow B307 set on the front end surface of the reading mark block 306 points to the position of the English teaching language sentence that has not been read and explained, thereby realizing reading marking, so as to facilitate faster locating of the position area where the explanation was not read when reading and explaining next time;

[0052] When the teaching board 3 is inserted into the separate storage and installation slot, the right end of the teaching board 3 is first inserted into the separate storage and installation slot. Since the bottom surface and the top surface of the inner end of the storage slot 105 of the present invention are respectively provided with a plug-in matching groove A106 with an inclined groove structure relative to the five separate storage and installation slots, when the limiting card column 309 is inserted into the storage slot 105, with the cooperation of the plug-in matching groove A106, the limiting card column 309 protruding from the spring storage slot 3011 can slide into the plug-in matching groove A106 without hindrance, and then be squeezed by the inclined surface of the plug-in matching groove A106, so that the limiting card column 309 protruding from the spring storage slot 3011 is squeezed into the spring storage slot 3011, thereby facilitating the insertion of the teaching board 3 into the separate storage and installation slot. When the end face contacts the right side face of the inner end of the separate storage and installation groove, the spring storage groove 3011 is opposite to the axis of the reciprocating through hole 1025. Under the resetting action of the reset spring B3012, the limiting clamping column 309 is inserted into the reciprocating through hole 1025, thereby limiting the position of the teaching board 3, so that the teaching board 3 cannot be taken out from the separate storage and installation groove before the limiting clamping column 309 is separated from the reciprocating through hole 1025. The present invention uses the limiting setting of the teaching board 3 to prevent the teaching board 3 from being taken out when the position limit of the teaching board 3 is not released, thereby preventing some uninformed students from erasing the English teaching language sentences written on the blackboard 301 by the teaching board 3 during cleaning, thereby affecting the subsequent English language reading and explanation;

[0053] Furthermore, the present invention facilitates alternating use of the five sets of teaching boards 3, and eliminates the need to erase the English teaching language sentences written on the blackboard 301 of the set of teaching boards 3 that have not been read and explained during teaching applications.

[0054] When it is necessary to release the position limit of the teaching board 3, the raised end of the cam 1012 needs to be rotated to face the reciprocating matching column 1022, so that the reciprocating matching column 1022 can squeeze the limiting column 309 to achieve the separation of the limiting column 309 and the reciprocating through hole 1025, so as to facilitate the removal of the teaching board 3. Furthermore, the front end surface of the rotating shaft 1011 of the present invention is provided with a rotating block 109, and the front end surface of the rotating block 109 is provided with an embedded groove 1013. The rear side surface of the inner end of the embedded groove 1013 is provided with a marking arrow A1015, and the arrow end of the marking arrow A1015 is aligned with the raised end of the cam 1012. The raised ends of the wheels 1012 are in the same direction, and an embedded block 1016 is embedded in the embedded groove 1013 of the present invention. The front end surface of the embedded block 1016 is annularly arrayed with ten number marks 1018. The ten number marks 1018 are "0", "1", "2", "3", "4", "5", "6", "7", "8", and "9". Therefore, through the coordination of the ten number marks 1018 and the marking arrow A1015, the teacher can set the value of releasing the position limit of the teaching board 3 by himself. For example, first fix the two embedded blocks 101 6, remove the locking bolt 1019 of the embedded block 1016 on the upper side, align the number mark 1018 of "1" on the embedded block 1016 on the upper side with the position of the marked arrow A1015, and align the number mark 1018 of "9" on the embedded block 1016 on the lower side with the position of the marked arrow A1015, and then re-tighten the locking bolt 1019 to fix the embedded blocks 1016 after the two positions are adjusted. At this time, when the teacher needs to release the position limit of the teaching board 3, the teacher who knows the correct release value only needs to move the number mark 1018 on the upper side to release the position limit of the teaching board 3. The number mark 1018 of "1" in the embedded block 1016 on the side is rotated to face directly downward, and the number mark 1018 of "9" in the embedded block 1016 on the lower side is rotated to face directly upward. At this time, the raised end of the cam 1012 will face the stop block 1023, so that the two limit posts 309 of each group of teaching boards 3 are both received in the spring receiving groove 3011. At this time, when the teacher needs to take out the teaching board 3, he only needs to grasp the gripping part formed by the through gripping opening 303 and the gripping groove 304 to pull the teaching board 3 to take out the teaching board 3 from the separate receiving and mounting groove.

[0055] Finally, it should be noted that when describing the positions of various components and the matching relationships between them, the present invention usually takes one / a pair of components as an example. However, those skilled in the art should understand that such positions, matching relationships, etc. are also applicable to other components / other pairs of components.

[0056] The above description is merely an exemplary embodiment of the present invention and is not intended to limit the scope of protection of the present invention. The scope of protection of the present invention is determined by the appended claims.
