[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0033] See also Figure 1-6 As shown, the present invention is a lifting type English teaching information publishing and display device, comprising a lifting block 1 and a display device 2 located directly above the lifting block 1, an adjustment port 103 extending from top to bottom is provided in the middle of the front side of the lifting block 1, a sliding port 102 extending from top to bottom is provided inside the lifting block 1 behind the adjustment port 103, a sliding block 6 is slidably provided inside the sliding port 102 behind the display device 2, an adjustment block 5 sliding inside the adjustment port 103 is fixed on the front side of the sliding block 6, and a plurality of card blocks 104 uniformly distributed linearly from top to bottom are fixed on the left and right parts of the inner side of the sliding port 102;

[0034] Among them, the interior of the sliding opening 102 is penetrated by a middle-shaped opening 601, and the left and right end positions of the middle-shaped opening 601 are slidably provided with a telescopic block 7 inserted between the two clamping blocks 104. When the telescopic opening moves from the position between the two clamping blocks 104, the telescopic block 7 no longer limits the sliding block 6, thereby controlling the movement of the sliding block 6. At the same time, after the telescopic block 7 moves from the interior of the middle-shaped opening 601 to the position between the two middle-shaped openings 601, the telescopic block 7 can support and limit the sliding block 6.

[0035] A mounting plate 4 is provided at the upper end of the lifting block 1, and the mounting plate 4 is screwed to the lifting block 1 by bolts. A folding plate 3 is provided just above the adjusting block 5 and is located inside the sliding opening 102, and the left and right parts of the folding plate 3 are located in front of the clamping block 104. After the folding plate 3 is extended by the sliding block 6, the folding plate 3 will be fully unfolded inside the adjusting opening 103 and block the inside of the sliding opening 102.

[0036] A metal plate 301 is fixed to the upper end of the folding plate 3, and a magnetic block 401 that is attracted to the metal plate 301 is fixed to the lower end surface of the mounting plate 4. The metal plate 301 is attracted by the magnetic block 401, so that the metal plate 301 is installed on the top surface of the sliding opening 102. When the folding plate 3 is pulled by the sliding block 6, it will not fall off. At the same time, the adsorption between the magnetic block 401 and the metal plate 301 facilitates the disassembly of the folding plate 3.

[0037] Locking plates 105 are fixed to the rear parts of the left and right sides of the lifting block 1. By using the locking plates 105, the locking plates 105 can be installed on the wall through bolts, and the lifting block 1 can be installed on the wall. The bottom of the sliding opening 102 is fixed with a charging base 101, and the rear side of the display 2 is fixed with a power socket 201 at the same upper and lower position as the charging base 101. The power socket 201 is inserted into the charging base 101, so that the display 2 is charged.

[0038] Among them Figure 2 、 3 As shown in Figure 5, two movable plates 8 are fixed on the front side of the adjusting block 5 and are symmetrically arranged in an upper and lower manner, and the movable plate 8 is slidably connected to the front side of the lifting block 1. A pushing block 701 is provided between the two movable plates 8 on the left and right sides of the display 2. An extrusion port 501 is provided inside the adjusting block 5 and is connected to the inside of the middle-shaped opening 601. There are two extrusion plates 702 arranged symmetrically in the inside of the extrusion port 501, and the extrusion plates 702 are fixedly connected to the adjacent telescopic blocks 7. A spring 703 is fixed at the position between the two extrusion plates 702. A movable rod 704 is fixed between the pushing block 701 and the adjacent extrusion plates 702. Since the movable rod 704 is located between the two movable plates 8, when the pushing block 701 pushes the movable rod 704 to move, the pushing block 701 will drive the extrusion plate 702 to move through the movable rod 704, so that the extrusion plate 702 will move inside the middle-shaped opening 601 and the extrusion port 501.

[0039] Among them Figure 2 、 3As shown in Figure 4, the front side of the adjustment block 5 above the extrusion port 501 is provided with an assembly hole 502, and the upper end surface of the adjustment block 5 is provided with a screw hole 503 connected to the inside of the assembly hole 502. The rear side of the display 2 is fixed with an assembly rod 202 inserted into the internal position of the assembly hole 502, and the peripheral side of the assembly rod 202 is penetrated with a plug hole 203 at the upper and lower positions of the screw hole 503. The lower end of the folding plate 3 is fixed with a connecting plate 302 connected to the upper end surface of the adjustment block 5, and the upper surface of the connecting plate 302 is penetrated at the position corresponding to the screw hole 503. There is a through hole 303, and the upper end of the connecting plate 302 is provided with a locking screw 9 that passes through the through hole 303, the screw hole 503 and the internal position of the plug hole 203. The upper end surface of the connecting plate 302 on the left and right sides of the through hole 303 is penetrated by a positioning hole 304. The upper end surface of the adjusting block 5 is fixed with a positioning rod 504 that is inserted into the internal position of the positioning hole 304. Since the connecting plate 302 is sleeved on the peripheral position of the positioning rod 504 through the positioning hole 304, the positioning rod 504 limits the positioning hole 304, so that the connecting plate 302 will not move at will;

[0040] When the folding plate 3 and the sliding block 6 need to be disassembled, the mounting plate 4 can be disassembled at the upper end surface of the lifting block 1, thereby releasing the metal plate 301 from the magnetic block 401. At this time, the telescopic block 7 can be directly moved away from the position between the two clamping blocks 104, and the sliding block 6 can be controlled to move upward inside the sliding opening 102 to disassemble the display 2 and the folding plate 3. At the same time, the locking screw 9 can be screwed out of the screw hole 503, so that the connecting plate 302 can be taken out at the position of the positioning rod 504, and the folding plate 3 and the sliding plate can be disassembled.

[0041] A specific application of this embodiment is: through the arrangement and use of the above structure, the lifting block 1 is installed on the wall of the classroom, and the information on English teaching is displayed through the display 2. At the same time, when the display 2 needs to be lifted or lowered, the two pushing blocks 701 on the left and right sides of the display 2 are pushed in relative directions, whereby the pushing blocks 701 push the two squeezing plates 702 to move relative to each other inside the middle-shaped opening 601 through the movable rod 704, so that the squeezing plates 702 drive the telescopic block 7 from the position between the two clamping blocks 104 to the inside of the middle-shaped opening 601, so that the clamping block 104 no longer limits the sliding block 6 and the adjusting block 5. At this time, the display 2 can be directly pushed to slide up and down on the front side of the lifting block 1, thereby moving the display 2 to the front of the lifting block 1. After the display 2 has reached the corresponding position on the side, the pushing block 701 can be loosened, whereby the spring 703 between the two squeezing plates 702 will push it to move in the opposite direction and make the telescopic block 7 move back to the position between the upper and lower clamping blocks 104, thereby limiting the position of the display 2 and preventing the display 2 from moving further. At the same time, after class or after school, in order to ensure that the display 2 can work normally the next day, the display 2 can be moved downward, so that the power socket 201 at the lower part of the rear side of the display 2 can be electrically connected to the internal position of the charging base 101, and the display 2 can be charged. When the display 2 moves, it will drive the folding plate 3 to move. When the display 2 moves to the lowermost position, the folding plate 3 will completely cover the space of the adjustment plate.

[0042] The above are only preferred embodiments of the present invention and do not limit the present invention. Any modification to the technical solutions described in the aforementioned embodiments, any equivalent replacement of some of the technical features therein, and any modification, equivalent replacement, and improvement made are within the scope of protection of the present invention.
