[0052] It should be noted that the modifications of "one" and "plurality" mentioned in the present disclosure are illustrative rather than restrictive, and those skilled in the art should understand that unless otherwise clearly indicated in the context, it should be understood as "one or more".

[0053] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0054] Example 1, reference Figure 1-6The flap cover of the notch of the lifting plate of the study table includes a base 1, a locking device, a pin 3, a flap body 4, and a torsion spring 5; the base 1 is fixed on the main panel 19 of the study table, a fixed plate 6 is fixed on the flap body 4, and the fixed plate 6 is fixed on the pin 3, and the locking device is located at the middle position of the flap body 4; the locking device includes a support block 2, an upper locking member, and a lower locking member; the support block 2 is sleeved on the pin 3, and the pin 3 is rotated relative to the support block 2, the upper locking member is fixed at the lower end of the support block 2, and the lower locking member is arranged on the base 1, and one end of the torsion spring 5 is connected to the flap body 4, and the other end is connected to the support block 2. When the flap body 4 is turned over, it has at least a locking state abutting against the locking device; when the flap body 4 is in the locked state, it is on the same plane as the lifting plate 20. By pressing the flap body 4, one end of the flap body 4 abuts against the locking device, and the locking device is driven to lock or unlock. When in the locked state, the flap body 4 and the lifting plate 20 are on the same plane, filling the gap on the main panel 19 of the study table, so that the lifting plate 20, the flap body 4, and the main panel 19 of the study table form a complete table board, preventing the school supplies placed on the study table 19 from falling to the ground, while ensuring the aesthetics of the table board. When in the unlocked state, the flap body 4 is in a flipped state, staggered with the lifting plate 20, so that the lifting plate 20 can be raised and lowered through the gap.

[0055] The upper locking member includes a locking rod 7 ; the locking rod 7 is fixed on the supporting block 2 .

[0056] The lower locking member includes a fixed block 8, an elastic hook 9, and a return spring 10; the fixed block 8 is fixedly arranged on the base 1, and a cavity 11 is opened in the fixed block 8, the elastic hook 9 is slidably arranged in the cavity 11, and one end of the return spring 10 is connected to the elastic hook 9, and the other end is connected to the inner wall of the cavity 11. When the flap body 4 is in a locked state, the flap body 4 squeezes the support block 2 to move downward, and the support block 2 moves downward to drive the locking rod 7 to move together, and one end of the locking rod 7 abuts against the elastic hook 9, so that the elastic hook 9 moves in the cavity 11, so that the elastic hook 9 and the inner wall of the cavity 11 are squeezed against each other, so that the elastic hook 9 clamps the locking rod 7. Among them, the upper and lower locking members can refer to the technical principle of the switch pressing self-locking buckle in the prior art.

[0057] The elastic hook 9 includes a moving block 12, a first clamping portion 13, and a second clamping portion 14; the moving block 12 is movably arranged in the cavity 11, and one end of the return spring 10 is connected to the moving block 12; the first clamping portion 13 and the second clamping portion 14 are respectively fixedly arranged on the moving block 12, and the first clamping portion 13 and the second clamping portion 14 are arranged relatively, wherein the first clamping portion 13 and the second clamping portion 14 are particularly elastic; a horizontally arranged slide groove is provided on the moving block 12, and a limit pin 21 is inserted into the slide groove, and a guide groove 22 is provided on the inner wall of the fixed block 8, and one end of the limit pin 21 is inserted into the guide groove 22; a guide block 23 is provided in the guide groove 22, and the guide block 23 has a first inclined surface 24 and a fourth inclined surface 27, and the guide groove 22 has a second inclined surface 25 and a third inclined surface 26. The limit pin 21 moves cyclically along the first inclined surface 24, the second inclined surface 25, the third inclined surface 26, and the fourth inclined surface 27. Pressing the flap body 4 moves the support block 12 downward, and at the same time drives the locking rod 7 to move, so that the locking rod 7 applies pressure to the moving block 12, driving the moving block 12 to move downward, and when the moving block 12 moves, it drives the first clamping part 13 and the second clamping part 14 to move together, and the first clamping part 13 and the second clamping part 14 will contact the inner wall of the cavity 11 during the movement, and the inner wall of the cavity 11 applies pressure to the first clamping part 13 and the second clamping part 14, so that the first clamping part 13 and the second clamping part 14 are relatively close or separated, thereby locking or unlocking the locking rod 7. At the same time, the limit pin 21 on the moving block 12 moves in the guide groove 22, and the limit pin 21 moves under the action of the first inclined surface 24, the second inclined surface 25, the third inclined surface 26, and the fourth inclined surface 27 respectively.

[0058] Specifically, when the moving block 12 drives the first clamping part 13 and the second clamping part 14 to move downward, the first clamping part 13 and the second clamping part 14 contract (approach each other) to lock the locking rod 7. At this time, when the limit pin 21 moves downward from the initial position, it contacts the first inclined surface 24, so that the limit pin 21 moves along the surface of the first inclined surface 24 to the second inclined surface 25; thereby reaching the locked state. When the flap body 4 is pressed again, the moving block 12 moves downward, so that the first clamping part 13 and the second clamping part 14 contract again (approach each other), and at this time, the limit pin 21 moves downward from the second inclined surface 25 to the third inclined surface 26, moves to the fourth inclined surface 27 through the third inclined surface 26, and finally moves to the initial position, thereby reaching the unlocked state. Thus, the flap body 4 is flipped.

[0059] One end of the locking rod 7 is configured as a tapered portion 15; when the tapered portion 15 is located between the first clamping portion 13 and the second clamping portion 14, the tapered portion 15 abuts against the moving block 12. After moving to a certain distance, the first clamping portion 13 and the second clamping portion 14 clamp the tapered portion 15, thereby achieving a locked state.

[0060] The locking device further includes a guide rod 16, which is fixed on the support block 2, and is arranged parallel to the locking rod 7, and one end of the guide rod 16 is inserted into the base 1 and slidably cooperates with the base 1. Under the action of the guide rod 16, the locking rod 7 is guided.

[0061] The fixing block 8 is provided with a clamping block 17, and the base 1 is provided with a clamping slot 18 for the clamping block 17 to be clamped in. Thus, the fixing effect of the fixing block 8 is improved.

[0062] Example 2, reference Figure 7-8 The difference from the first embodiment is that there are several locking devices, two in the present application, and the pin shaft 3 is rotatably inserted into the plurality of locking devices.
