Description

Technical Field

[0001] The present invention relates to the field of smart education, and in particular to a smart education system and an educational experimental device thereof. Background Art

[0002] Smart education, also known as educational informatization, refers to the process of comprehensively and deeply applying modern information technology in the field of education to promote educational reform and development. Especially in the early childhood education period, it is necessary to use various props to demonstrate and teach children so that they can initially understand the practical use of the teaching aids, thereby helping children to recognize in advance. By adding a variety of social items and equipment within the educational institution for children to interact or use, it can effectively cultivate children's habits of using equipment independently or actively.

[0013] Beneficial effects of the present invention:

[0014] 1. The present invention is provided with a combination of a power-off sensor, a sliding key plate, a first return spring and a support baffle. When the cylinder drives the support baffle and the guide synchronous plate to close the gate towards each other, when a child runs past between the guide synchronous plates, the provision of the anti-collision plastic strip can prevent the guide synchronous plate from directly colliding with the child. At the same time, when the anti-collision plastic strip contacts the child, the guide synchronous plate will drive the sliding key plate to move on the surface of the support baffle until the trigger guide rod is inserted into the interior of the power-off sensor, so that the power-off sensor can be triggered, causing the power-off sensor to cut off the power to the cylinder, thereby preventing the cylinder from continuously feeding and driving the guide synchronous plate to pinch the child. At the same time, when the child passes in front of the anti-collision plastic strip, the elasticity of the first return spring can drive the trigger guide rod to move out of the interior of the power-off sensor, so that the cylinder can be powered normally.

[0015] Second, through the combination of the auxiliary disinfection device and the alignment release device, when the support baffle moves outward, it can drive the rack to rotate the winding wheel, causing the connecting rope to pull the connecting frame and the sponge sheet to move on the surface of the fingerprint sensor. At the same time, when the connecting frame moves upward to the extreme position, it can drive the limit push plate to squeeze the limit plug rod and move upward to the extreme position, causing the blocking head to be removed from the top of the transmission tube, so that the disinfectant inside the storage cavity can flow from the transmission tube into the interior of the dripping head, and the dripping head is vertically aligned with the top of the fingerprint sensor, so that the disinfectant can be immersed in the interior of the sponge sheet. When the sponge sheet is reset again, the disinfectant can be applied to the surface of the fingerprint sensor to complete the disinfection of the fingerprint sensor surface, thereby preventing cross infection when young children use this device.

[0031] The positioning release device 23 includes a limiting plug rod 231, a plugging head 232, a third return spring 233, a receiving cavity 234, a support frame 235, a dripping head 236, a transmission conduit 237 and a cross bar 238.

When the limiting push plate 214 is out of contact with the cross bar 238, the elasticity of the third reset spring 233 can drive the sealing head 232 to be quickly inserted into the top end of the transmission conduit 237, so as to prevent excessive flow of disinfectant into the drip head 236.

[0032] The support frame 235 is fixedly installed on the front end top of the support shell 22, and the second bevel gear 212 is rotatably installed inside the top end of the support shell 22 away from the alignment release device 23, and the first bevel gear 28 is engaged with the second bevel gear 212. When the transmission gear 29 rotates, it can drive the first bevel gear 28 and the second bevel gear 212 to rotate synchronously.

[0033] The limiting vertical rod 217 and the connecting frame 215 are respectively slidably inserted into the movable groove 26 and the supporting sleeve 27. The cylinder 11 is fixedly mounted on the inner wall of the supporting shell 22 near the first bevel gear 28. The power-off sensor 12 is horizontally aligned with the trigger guide rod 110. The rack 15 is engaged with the transmission gear 29. The bottom surface of the sponge sheet 216 is in contact with the top surface of the fingerprint sensor 24. When the sponge sheet 216 is reset, the disinfectant can be evenly applied to the surface of the fingerprint sensor 24.

[0034] The bottom end of the dripping head 236 is vertically aligned with the top end of the fingerprint sensor 24. The interior of the dripping head 236 and the storage cavity 234 are both hollow, and the transmission conduit 237 is interconnected with the storage cavity 234 and the dripping head 236 respectively. The side end of the limiting push plate 214 away from the second return spring 218 is set at a 45° slope, which can continuously push the cross bar 238 upward.

[0035] The front end centers of the power-off sensor 12 and the blocking bar 14 are respectively provided with sockets adapted to the trigger guide rod 110, and the side ends of the support baffle 16 close to the cylinder 11 are symmetrically provided with sliding grooves adapted to the sliding key plate 17. The power-off sensor 12 is electrically connected to the cylinder 11, and the positioning cover 25 is fixedly installed on the top of the support sleeve 27 by screws, which makes it easy to remove the positioning cover 25 from the top of the support sleeve 27.

[0036] Working principle: When in use, first place the device in the designated working area, and step on the surface of the pedal 3 marked with an indicator arrow to guide the child to step. When the child's finger touches the fingerprint sensor 24, the fingerprint sensor 24 is electrically connected to the cylinder 11, so that the fingerprint sensor 24 will issue an opening command to the cylinder 11 after receiving the correct instruction, causing the cylinder 11 to drive the support baffle 16 and the guide synchronization plate 18 to move toward the inner side of the support shell 22, so that the child can pass between the support shells 22 and the support shells 22. At the same time, when the support baffle 16 moves outward, it can drive the rack 15 to move at the bottom end of the transmission gear 29, causing the transmission gear 29 to drive the first bevel gear 28 to rotate at the same time, through the first bevel gear 28. When the first bevel gear 28 rotates, it can drive the second bevel gear 212 and the winding wheel 211 to rotate at the same time, so that the connecting rope 213 can pull the connecting frame 215 to move upward until it is in contact with the surface of the fingerprint sensor 24. At the same time, when the connecting frame 215 moves upward to the limit position, it can drive the limit push plate 214 to squeeze the cross bar 238 and the limit plug 231 to move upward to the limit position, causing the blocking head 232 to be taken out from the top inside of the transmission conduit 237. At this time, the disinfectant inside the storage cavity 234 flows from the inside of the transmission conduit 237 to the inside of the dripping head 236, and is vertically aligned with the top of the fingerprint sensor 24 through the dripping head 236, so that the disinfectant dripping from the dripping head 236 will soak into the inside of the sponge sheet 216. When the cylinder 11 drives again When the support baffle 16 and the guide synchronous plate 18 are reset outward, the rack 15 can be driven to move in the opposite direction at the bottom end of the transmission gear 29, causing the first bevel gear 28, the second bevel gear 212 and the winding wheel 211 to rotate in the opposite direction at the same time, loosening the connecting rope 213. At this time, the elasticity of the second reset spring 218 can drive the connecting frame 215 to move downward quickly until the connecting frame 215 moves to the inside of the support sleeve plate 27 again, completing the reset work of the connecting frame 215 and the sponge sheet 216. During the movement of the connecting frame 215, the limiting vertical rod 217 slides inside the movable groove 26, so that the connecting frame 215 can be ensured to move in a straight line while preventing the connecting frame 215 from falling off. When the sponge sheet 216 is in the index position, the connecting frame 215 can be prevented from falling off. When the surface of the fingerprint sensor 24 slides downward, the disinfectant inside the sponge sheet 216 will be smeared on the surface of the fingerprint sensor 24, completing the automatic disinfection of the fingerprint sensor 24. When the device is in use, when the guide synchronization plate 18 is closed and contacts with the child, the anti-collision plastic strip 19 is set to prevent the guide synchronization plate 18 from having a rigid collision with the child. At the same time, when the guide synchronization plate 18 is subjected to pressure, it will drive the sliding key plate 17 to move toward the rear end in the sliding groove on the side end of the support baffle 16, so that when the sliding key plate 17 moves, it can drive the trigger guide rod 110 to penetrate the blocking strip 14 and insert into the interior of the power-off sensor 12. The power-off sensor 12 is electrically connected to the cylinder 11, so that when the trigger guide rod 110 enters the interior of the power-off sensor 12,A power-off command can be issued to the cylinder 11 to prevent the cylinder 11 from continuously applying pressure to the support baffle 16, thereby avoiding secondary injury to the child. When the child breaks away from between the anti-collision plastic strips 19, the elasticity of the first return spring 13 drives the sliding key plate 17 and the guide synchronization plate 18 to move outward, causing the trigger guide rod 110 to be removed from the interior of the power-off sensor 12, so that the cylinder 11 can be powered again, facilitating the normal use of the cylinder 11 again.
