The folding blocks a5 are distributed at both ends of the board body a2. The board body a2 is connected with a total of five folding blocks a5. The pull handle a3 is pulled to cooperate with the bottom pulley of the board body a2 to slide, so as to bend through its own folding performance, it can smoothly enter the upper slideway for retraction, so that the computer software will not obstruct the students' sight during the teaching demonstration. .
[0034] The cleaning tank a1 includes a screen saver roller a11, an anti-detachment hoop a12, a frame cleaning seat a13, and a tank body a14. The tank body a14 is integrally connected to the inner wall of the folding block a5. The center of the stripping a12 is nested and connected, the two ends of the anti-stripping a12 are welded and connected to the outer wall of the groove body a14, the bottom of the clear frame seat a13 is meshed with the two ends of the screen saver roller a11, and the surface of the groove body a14 is connected to the screen saver roller a11. Overall active coordination, the screen saver roller a11 is distributed on the surface of the groove body a14, forming a clearance fit with the surface of the groove body a14, nesting through the anti-detachment hoop a12 to prevent it from falling off, and the two ends are meshed with the bottom of the frame seat a13. , the screen saver roller a11 is beneficial to indirectly drive the screen saver roller a11 to wipe the screen surface of the demonstration when the upper handle a3 pulls the board body a2 to slide, and cleans up the fingerprints or dust on the surface to ensure that the surface does not There is a foreign body sticking.
[0035] The frame cleaning seat a13 includes a brush rod d1, an auxiliary turntable d2, a roller fixing groove d3, and a colloid block d4. The interior of the fixing roller groove d3 is engaged with both ends of the screen saver roller a11, and the bottom of the brush rod d1 is connected. It is connected with the surface of the colloid block d4, the inside of the colloid block d4 is movably matched with both ends of the auxiliary turntable d2, the two sides of the fixing roller groove d3 are in clearance fit with the colloid block d4, and the bottom of the auxiliary turntable d2 is matched with the auxiliary turntable d2. The top is welded and connected, and the brush rod d1 is a small brush rod with flat soft hair as a whole, and is embedded and connected with the surface of the colloid block d4 through the bottom. The bottom of the brush rod is embedded and fixed, and the brush rod d1 is helpful for inserting from the gap around the body to clean the dust that has fallen and adhered between the infrared stripe and the launch tube, so as to avoid dust covering the infrared stripe and launch tube, resulting in Touch sensitivity, the problem of reduced sensitivity occurs.
[0036] The specific working principle is as follows:
[0037] In the present invention, the sliding wheel 3 assists the supporting frame 2 to move to a designated position, and cooperates with the equipment table 1 at the upper end to demonstrate the development and teaching of electronic computer software. When starting to use, the closing plate 111 in the airtight cover 11 can be slid with the inner loading slideway 113 in the fixing frame 114, so that the pull handle a3 is pushed to the plate body a2, and the pulley at the bottom of the plate body a2 is on the slideway. After sliding, it is in an arc-shaped state after entering the inner loading slideway 113, so it is bent by the folding block a5, and at the same time, the top blocking block a4 is disengaged and expanded to the two ends of the demonstration stand 12. Due to the displacement, the cleaning slot is The a1 is linked together, the screen saver roller a11 rotates under the cooperation of the groove body a14 and the anti-detachment hoop a12, the two ends drive the clear frame seat a13 through the fixing roller groove d3 to carry out displacement, and the rolled screen saver roller a11 passes the surface to the display frame 122. The surface is wiped, and the dust and fingerprints that stick to the screen surface are wiped. The brush rods d1 at both ends are attached between the infrared stripe and the launch tube in the gap between the frame body due to the auxiliary cooperation between the auxiliary turntable d2 and the colloidal block d4. To avoid the dust covering the infrared stripe and the emission tube, the problem of touch sensitivity and sensitivity reduction occurs. In conjunction with the displacement of the internal loading slideway 113, the folding block a5 is folded into a corresponding arc shape, and the screen saver roller a11 wipes the screen on the surface of the all-in-one machine 121 before or after the use starts, and wipes off the dust and fingerprints. The brush rod d1 in the seat a13 is inserted into the gap between the frames to clean the dust that has fallen and adhered between the infrared stripe and the emission tube, so as to avoid the problems of reduced touch sensitivity and sensitivity.
