[0014] The beneficial effects of the present invention are as follows:

[0015] 1. The present invention is newly designed with a sliding limit assembly. The first protrusion is forced to press the first spring downward. When the return rod passes the area where the first protrusion is located, the pedal is released, the second spring drives the pedal to reset, the first protrusion rises again, and clamps the return rod.

[0016] 2. The present invention is equipped with an adjustable support assembly. By rotating the handle, the two sliding blocks are driven to slide toward the middle of the top of the fixed plate. At this time, the two connecting pieces are forced to rotate downward, increasing their range in the longitudinal direction, and gradually pushing the trapezoidal block to above the ground, but not in contact with the ground. At this time, the device is pushed to move. The bottom surface of the trapezoidal block is a large-area rectangle, which can assist the device in providing a supporting force when it tilts to the left or right sides. When parked, the trapezoidal block can also directly contact the ground to form another supporting point.

[0017] 3. The present invention is equipped with a display component that is easy to clean. By repeatedly squeezing the pressurized soft cylinder, the water storage box is pressurized so that the water in the water storage box can reach the sponge bar through the U-shaped tube. After the U-shaped tube is completely soaked in advance by the wave groove, the sponge bar is moved from right to left to clean the whiteboard. The moving block at the bottom of the sponge bar can move on the guide rod to complete the guiding function. After being reset again, it can be used repeatedly, thereby achieving fast and convenient whiteboard cleaning. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0029] like Figures 1 to 9 As shown, an embodiment of the present invention provides an educational work information archive display teaching device, including a fixed plate 1, a support component 2 is movably connected to the bottom of the fixed plate 1, and further includes:

[0031] The sliding limit assembly 4 comprises a cross bar 41, a pull rod 42 is movably hinged on the outer edge of the cross bar 41, a return rod 43 is movably hinged on the right side of the pull rod 42, a guide block 44 is movably clamped on the front outer edge of the return rod 43, a first protrusion 45 is movably installed inside the guide block 44, a second protrusion 46 is movably installed on the right side of the first protrusion 45, a first spring 47 is elastically connected to the bottom of the first protrusion 45, a U-shaped block 48 is elastically connected to the bottom of the first spring 47, the right top of the U-shaped block 48 is fixedly connected to the second protrusion 46, an oil storage tank 49 is provided at the bottom of the U-shaped block 48, spring plates 410 are elastically connected to both ends of the oil storage tank 49, a pedal 411 is movably hinged on the right side of the return rod 43, and two second springs 412 are elastically connected to the bottom of the pedal 411;

[0032] By lightly stepping on the pedal 411, the force range of the second spring 412 is shortened, and the return rod 43 moves to the right in the guide block 44. The first protrusion 45 is forced to move downward in the guide block 44, squeezing the first spring 47. When the return rod 43 passes the area where the first protrusion 45 is located, the pedal 411 is released, the second spring 412 drives the pedal 411 to reset, and the first protrusion 45 is also raised again in the guide block 44 under the action of the reset first spring 47, and the return rod 43 is clamped. At this time, the friction plate 34 will be pulled close to the rubber wheel 33 by the cross bar 41 and the pull rod 42 to form a fixing effect. The pedal 411 is stepped on to the bottom. At this time, the return rod 43 will squeeze the second protrusion 46 to the right in the guide block 44 to make it move downward, and the U-shaped block At this time, the force 48 will also squeeze the oil stored in the oil storage tank 49 downward. The oil is squeezed by the U-shaped block 48 with a flat bottom and moves to the spring plates 410 on both sides of the oil storage tank 49.

At this time, the pressure on the pedal 411 is released, and the second spring 412 drives the pedal 411 and the return rod 43 to move. When the return rod 43 moves to the leftmost side in the guide block 44, the pull rod 42 releases the pulling of the friction plate 34, and the rubber wheel 33 is unlocked. The oil level in the oil storage tank 49 gradually rises during the reset of the two spring plates 410, and the first spring 47, the first protrusion 45 and the second protrusion 46 are moved and reset again.

[0034] By rotating the handle 25, the two sliding blocks 21 are driven to slide toward the middle of the top of the fixed plate 1. At this time, the two connecting pieces 22 are forced to rotate downward, increasing their range in the longitudinal direction, and gradually pushing the trapezoidal block 23 to the top of the ground, but not in contact with the ground. At this time, the device is pushed to move. The bottom surface of the trapezoidal block 23 is a large-area rectangle, which can provide a supporting force when the device is tilted to the left or right sides. When parked, the trapezoidal block can also be directly in contact with the ground to form another supporting point;

[0035] The moving assembly 3 includes an inclined rod 31, which is fixedly connected to the bottom of the fixed plate 1. A cross plate 32 is movably hinged at the bottom end of the inclined rod 31. Two sets of rubber wheels 33 are rotatably installed on the left and right sides of the cross plate 32. The tops of the two rubber wheels 33 on the right side are movably hinged with friction plates 34. The inner sides of the two friction plates 34 are fixedly connected to the cross rod 41. The guide block 44 is fixedly installed on the top of the cross plate 32. The bottom of the second spring 412 is elastically connected to the right side of the cross plate 32.

[0036] The contact area with the smooth ground can be enlarged by the multiple rubber wheels 33 fixed by the cross plate 32. The friction plate 34 will be pulled close to the rubber wheel 33 by the cross bar 41 and the pull rod 42 to form a fixing effect.

[0037] The display assembly 5 includes a display screen 51, which is fixedly mounted on the top of the fixed plate 1, speakers 52 are fixedly mounted on both sides of the display screen 51, a heat sink 53 is fixedly connected to the back of the display screen 51, and two fans 54 are fixedly mounted on the back of the heat sink 53;

[0038] By increasing the stroke of the two hydraulic rods 61, the whiteboard 62 is raised to expose the display screen 51, and the demand for audio-visual teaching is met through the display screen 51 and the speaker 52. During multimedia use, the two fans 54 will rotate to take away the accumulated heat of the heat sink 53;

[0039] The display assembly 6 includes two hydraulic rods 61, the bottoms of the two hydraulic rods 61 are fixedly connected to the top of the fixed plate 1, a whiteboard 62 is fixedly installed on the top of the two hydraulic rods 61, a U-shaped tube 63 is fixedly installed on the left side of the top of the whiteboard 62, a sponge bar 64 is movably installed on the front bottom of the U-shaped tube 63, two wave grooves 65 are provided inside the sponge bar 64, a shift block 66 is fixedly installed on the bottom of the sponge bar 64, a guide rod 67 is inserted in the middle of the shift block 66, and the guide rod 67 is fixedly installed on the bottom of the whiteboard 62, a water storage box 68 is fixedly connected to the bottom of the back side of the U-shaped tube 63, and a pressurized soft cylinder 69 is fixedly connected to the left side of the water storage box 68;

[0040] By squeezing the pressurizing soft cylinder 69 for many times, the water in the water storage box 68 is pressurized, so that the water in the water storage box 68 can reach the sponge bar 64 through the U-shaped tube 63. After the U-shaped tube 63 is completely soaked in advance by the wave groove 65, the sponge bar 64 is moved from right to left to clean the whiteboard 62. The moving block 66 at the bottom of the sponge bar 64 can move on the guide rod 67 to complete the guiding function.

[0041] The clamping assembly 7 includes two rotating blocks 71, and the two rotating blocks 71 are movably connected to the top of the whiteboard 62. The front bottom of the two rotating blocks 71 is fixedly connected with a clamping plate 72. The inner walls of the back sides of the two rotating blocks 71 are elastically connected with third springs 73. The other ends of the two third springs 73 are elastically connected to the whiteboard 62. The right side of the right rotating block 71 is movably hinged with a round rod 74, and the right outer edge of the round rod 74 is movably hinged with an L-shaped block 75. A limiting rod 76 is movably inserted in the middle position of the left side of the L-shaped block 75, and the left end of the limiting rod 76 is fixedly connected to the back of the whiteboard 62.

[0042] By pressing the L-shaped block 75 downward, the L-shaped block 75 will drive the two rotating blocks 71 to rotate a certain angle around the top of the whiteboard 62 through the round rod 74 and squeeze the third spring 73. At this time, a gap will be formed between the clamping plate 72 and the whiteboard 62. After the paper is inserted into the gap, the pressure on the L-shaped block 75 is released. At this time, the third spring 73 is reset, driving the clamping plate 72 to be close to the whiteboard 62 again, thereby forming a clamping display effect.

[0043] Working principle:

[0044] When using the present invention, firstly, the device is moved to the area where it needs to be used by the moving component 3. When the device is pushed, the multiple rubber wheels 33 fixed by the cross plate 32 can expand the contact area with the smooth ground. In addition, in order to prevent the device from tipping over during movement, the support component 2 can be started in advance, and the two sliding blocks 21 are driven to slide toward the middle on the top of the fixed plate 1 by rotating the handle 25. At this time, the two connecting pieces 22 are forced to rotate downward, increasing their range in the longitudinal direction, and gradually pushing the trapezoidal block 23 to the top of the ground, but not in contact with the ground. At this time, the device is pushed to move again. The bottom surface of the trapezoidal block 23 is a large-area rectangle, which can provide a supporting force when the device tips over to the left or right sides.

[0045] When the equipment needs to be parked after moving, the pedal 411 is lightly stepped on, the force range of the second spring 412 is shortened, and the return rod 43 moves to the right in the guide block 44, and the first protrusion 45 is forced to move downward in the guide block 44, squeezing the first spring 47. When the return rod 43 passes the area where the first protrusion 45 is located, the pedal 411 is released, the second spring 412 drives the pedal 411 to reset, and the first protrusion 45 is also raised again in the guide block 44 under the action of the reset first spring 47, and clamps the return rod 43. At this time, the friction plate 34 is pulled close to the rubber wheel 33 by the cross bar 41 and the pull rod 42 to form a fixing effect;

[0046] When it is necessary to clamp a paper document, the L-shaped block 75 is pressed downward, and the L-shaped block 75 drives the two rotating blocks 71 to rotate a certain angle around the top of the whiteboard 62 through the round rod 74 and squeeze the third spring 73. At this time, a gap is formed between the clamping plate 72 and the whiteboard 62. After the paper is inserted into the gap, the pressure on the L-shaped block 75 is released. At this time, the third spring 73 is reset, driving the clamping plate 72 to be close to the whiteboard 62 again to form a clamp;

[0047] When the whiteboard 62 needs to be cleaned, the pressurizing soft cylinder 69 is squeezed several times to pressurize the water storage box 68, so that the water in the water storage box 68 can reach the sponge bar 64 through the U-shaped tube 63. After the U-shaped tube 63 is completely soaked in advance by the wave groove 65, the sponge bar 64 is moved from right to left to clean the whiteboard 62. The moving block 66 at the bottom of the sponge bar 64 can move on the guide rod 67 to complete the guiding function.

[0048] When multimedia functions are needed, the stroke of the two hydraulic rods 61 is increased first, the whiteboard 62 is raised and the display screen 51 is exposed, and the needs of audio-visual teaching are met through the display screen 51 and the speaker 52. During multimedia use, the two fans 54 will rotate to remove the accumulated heat of the heat sink 53;

[0049] After the teaching is completed, when the equipment needs to be moved again, the pedal 411 is stepped to the bottom. At this time, the return rod 43 will squeeze the second protrusion 46 to the right in the guide block 44 to make it move downward. The U-shaped block 48 will also be forced to squeeze the oil stored in the oil storage tank 49 downward. The oil is squeezed by the U-shaped block 48 with a flat bottom and moves toward the spring plates 410 on both sides of the oil storage tank 49. The first spring 47 and the first protrusion 45 on the left side will also sink, exposing an area for the return rod 43 to pass through. At this time, the pressure on the pedal 411 is released, and the second spring 412 drives the pedal 411 and the return rod 43 to move. When the return rod 43 moves to the far left in the guide block 44, the pull rod 42 releases the pull on the friction plate 34, completing the unlocking of the rubber wheel 33, and the oil gradually rises in the oil storage tank 49 during the reset of the two spring plates 410, and the first spring 47, the first protrusion 45 and the second protrusion 46 are moved and reset again. At this point, the work process ends.
