Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides a handheld turntable based on the principle of visual persistence, as shown in Figures 1-3. It includes a turntable 101 and a display mechanism. A support mechanism is provided below the turntable 101, and a rotation mechanism is provided between the turntable 101 and the support mechanism. By rotating the turntable 101, the display mechanism is rotated, so that the image in the display mechanism produces a visual persistence phenomenon as it rotates. The turntable 101 is disc-shaped, so that when a child directly rotates the turntable 101 with their hand, the outer wall of the turntable 101 will not cause injury to the child's hand, thereby improving the safety of operating the handheld turntable.

[0023] In a preferred embodiment, the display mechanism is located at the top of the turntable 101. The display mechanism is used to demonstrate the principle of visual persistence. The display mechanism includes a slot 201, which is located at the top of the turntable 101. A card 202 is movably connected to the inner wall of the slot 201. When the card 202 with a pattern is inserted into the slot 201, the turntable 101 rotates through the cooperation of the rotation mechanism, thereby causing the card 202 inserted into the slot 201 to rotate. As the card 202 rotates, the child can see the image on the card 202 in one direction, thus clearly understanding the principle of visual persistence. It is easy to operate, portable, and combines interactivity and education. The slot 201 is a one-way slot with no opening at the bottom, so that the card 202 can be stably inserted into the slot 201. At the same time, the slot 201 has a certain depth, so that after the card 202 is inserted into the slot 201, it will not fly out of the slot 201 as the turntable 101 rotates, thereby improving the stability of the display mechanism.

[0024] The support mechanism includes a handheld plate 301, which is located below the turntable 101. The rotating mechanism is located between the turntable 101 and the handheld plate 301. The handheld plate 301 has a certain length, which makes it convenient for children to hold the handheld plate 301 with one hand and rotate the turntable 101 with the other hand, thereby improving the convenience of operating the handheld turntable and the portability.

[0025] The rotating mechanism includes a connecting shaft 303, a connecting hole 302 at the top of the handheld plate 301, and an insertion hole at the bottom of the turntable 101. The outer wall of the connecting shaft 303 is movably connected to the inner wall of the insertion hole. A first limiting mechanism is provided at the top of the connecting shaft 303, and a second limiting mechanism is provided between the connecting shaft 303 and the connecting hole 302. By inserting the connecting shaft 303 into the insertion hole, the turntable 101 can rotate stably around the connecting shaft 303, providing stability for the handheld turntable operation.

[0026] The first limiting mechanism includes a limiting plate 304, the bottom end of which is fixedly connected to the top end of the connecting shaft 303. The top end of the turntable 101 has a countersunk hole 305, the interior of which is connected to the interior of the insertion hole. The outer wall of the limiting plate 304 is movably inserted into the inner wall of the countersunk hole 305. The diameter of the countersunk hole 305 is larger than that of the insertion hole. This allows the countersunk hole 305 to limit the limiting plate 304 after it is inserted into the countersunk hole 305 along with the connecting shaft 303, preventing the limiting plate 304 from entering the insertion hole. This prevents the turntable 101 from separating from the hand plate 301, thereby improving the stability of the turntable 101's rotation.

[0027] The second limiting mechanism includes a retaining ring 401. The outer wall of the retaining ring 401 is inserted into the inner wall of the connecting hole 302. The outer wall of the retaining ring 401 is provided with a first pressing protrusion 402. The outer wall of the connecting shaft 303 is inserted into the inner wall of the retaining ring 401. The inner wall of the retaining ring 401 is provided with a second pressing protrusion 403. The first pressing protrusion 402 allows the retaining ring 401 to be stably inserted into the connecting hole 302. The retaining ring 401 can be stably inserted into the connecting hole 302 without being subjected to a large external force. The second pressing protrusion 403 allows the connecting shaft 303 to be stably inserted into the retaining ring 401 without being subjected to a large external force. This improves the stability of the connection between the connecting shaft 303 and the handheld plate 301, thereby allowing the turntable 101 to rotate stably around the connecting shaft 303.

[0028] One end of the handheld plate 301 has a semi-circular surface 501. With the semi-circular surface 501, the outer wall of the handheld gripper wheel has no sharp corners, which will not cause injury to children and improves the safety of using the handheld wheel.

[0029] A decorative block 601 is fixedly connected to the end of the handheld plate 301 away from the semicircular surface 501. The decorative block 601 is cat paw shaped, which increases the grip length of the handheld plate 301, making it more convenient for children to use the handheld turntable. In this embodiment, the decorative block 601 is cat paw shaped, but it can also be set to dog paw, rabbit paw, etc., to increase the fun and aesthetics of the handheld turntable. The connection between the handheld plate 301 and the decorative block 601 is smooth, and children's hands will not feel any protrusion when sliding between the handheld plate 301 and the decorative block 601, which can prevent children from being scratched by the cup and further improve the safety of using the handheld turntable.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
