Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0018] Specific embodiments are given below.

[0019] Refer to Figures 1 to 4, an electric learning desktop telescopic structure, including a learning table body 1, a mounting frame 2 and a front and rear telescopic component 3, the bottom end of the learning table body 1 is installed with a mounting frame 2, and the front and rear telescopic component 3 is installed in the mounting frame 2; a table board 4 is fixedly connected to the top outer wall of the mounting frame 2, and books and learning tools can be placed on the table board 4, thereby improving the use effect of the equipment; a battery 5 is embedded in the top of the learning table body 1, and a button 6 is installed on one side of the learning table body 1, which is used to drive the learning table body 1, and then the battery 5 is used to control the movement of the learning table body 1. Power the device; the electrical output end of the battery 5 is electrically connected to the electrical input end of the button 6, and the electrical output end of the button 6 is electrically connected to the electrical input end of the motor 302. The button 6 and the motor 302 can be powered by the motor 302, so that the table plate 4 can be moved back and forth. A support column 7 is fixedly connected to the outer wall of the bottom end of the study table body 1, and a movable plate 8 is symmetrically fixedly connected to the outer wall of the bottom end of the support column 7. The study table body 1 can be moved to a specified position by the movable plate 8, and then the study table body 1 can be supported by the support column 7;

[0020] The front and rear telescopic components 3 include a motor base 301, a motor 302, a screw rod 303, a fixed sleeve 304, a threaded hole 305, a transmission shaft 306, a bearing base 307, a reducer 308, a guide square rod 309, a movable frame 3010, a locking block 3011 and a movable sleeve 3012. The motor base 301 is symmetrically fixedly connected to the inner wall of the bottom end of the mounting frame 2. The motor 302 is installed on the inner wall of one side of the motor base 301. One end of the output shaft of the motor 302 is fixedly connected to the screw rod 303. The fixed sleeve 304 is symmetrically fixedly connected to the outer wall of one side of the study table body 1. 04. A threaded hole 305 is provided on the outer wall of one end of the fixed sleeve 304 at the position corresponding to the screw rod 303. A guide square rod 309 is symmetrically fixedly connected to the outer wall of one side of the study table body 1. A movable frame 3010 is slidably connected to the outer wall of one side of the guide square rod 309. A movable sleeve 3012 is sleeved on the outer wall of one side of the movable frame 3010. A locking block 3011 is fixedly connected to the outer wall of one side of the movable frame 3010, and one side of the locking block 3011 is locked and connected to the movable sleeve 3012. One end of the movable sleeve 3012 is fixedly connected to the inner wall of the mounting frame 2.

[0021] Working principle: When it is necessary to increase the area of the tabletop 4, start the motor 302 on the motor base 301 to rotate the screw rod 303. Then, under the action of the threaded hole 305 on the fixed sleeve 304, the screw rod 303 moves along the fixed sleeve 304. Since the engaging block 3011 engages and limits the moving sleeve 3012, under the action of the reaction force, the moving frame 3010 on the moving sleeve 3012 is driven to move along the guiding square rod 309, thereby moving the mounting frame 2. When the mounting frame 2 needs to stop, turn off the motor 302 and start the reducer 308 to decelerate the transmission shaft 306 on the bearing seat 307, so that the screw rod 303 stops quickly, and the adjustment of the mounting frame 2 is turned off. Thus, the tabletop 4 is moved in front of the student, and a larger placement area is increased. The learning tabletop can be telescoped, thereby increasing the area of the learning tabletop, facilitating the placement of more items, and improving the use effect of the device.
