[0034] like Figures 1 to 11 As shown, an embodiment of the utility model provides an LED display device, which includes a housing 10, a power box 20 and a locking mechanism 30. The power box 20 is arranged on the housing 10; the locking mechanism 30 includes a hook 31, a base 32 and an operating structure 33. The hook 31 is hingedly arranged on one of the power box 20 and the housing 10, and the base 32 is fixedly arranged on the other of the power box 20 and the housing 10. The hook 31 has a locking position for engaging with the base 32 and an unlocking position for disengaging from the base 32. The operating structure 33 is movably arranged on the power box 20 or the housing 10, and the operating structure 33 can drive the hook 31 to switch between the locking position and the unlocking position.

[0035] By applying the technical solution of the utility model, the LED display device includes a box body 10, a power box 20 and a locking mechanism 30. When installing the power box 20, the operating structure 33 is operated to drive the hook 31 to move, so that the hook 31 is switched from an unlocked position disengaged from the card stand 32 to a locked position engaged with the card stand 32. Since the hook 31 is hingedly arranged on one of the power box 20 and the box body 10, and the card stand 32 is fixedly arranged on the other of the power box 20 and the box body 10, the power box 20 can be locked on the box body 10 by utilizing the engagement between the hook 31 and the card stand 32. When disassembling the power box 20, it is only necessary to reversely operate the driving structure to move the hook 31 from the locked position to the unlocked position, so that the hook 31 is separated from the card stand 32. Compared with the method of using screws or pins for plugging, it has the advantage of simple operation.

[0036] The locking mechanism 30 may be disposed on a side of the power box 20 or on an end of the power box 20 .

[0037] It should be noted that there is no specific connection between the setting position of the operating structure 33 and the setting position of the hook 31.

When the knob 331 is in the driving state, the knob 331 drives the hook 31 to move from the locked position to the unlocked position. When the knob 331 is in the separation state, the reset member 332 can provide a restoring force for the hook 31 to keep the hook 31 in the locked position. With the above-mentioned operating structure 33, when the knob 331 is rotated, the knob 331 is in contact with the hook 31 and switched from the separation state to the driving state, thereby driving the hook 31 to move from the locked position to the unlocked position. At this time, the hook 31 is separated from the deck 32, and the power box 20 can be removed from the housing 10. When installing the power box 20, first turn the knob 331 to separate it from the hook 31, and at the same time move the hook 31 to a locked position that cooperates with the base 32, and use the reset member 332 to provide a restoring force for the hook 31 to keep the hook 31 in the locked position.

[0040] like Figure 5 and Figure 6 As shown, the reset member 332 includes a reset spring, the hook 31 is hinged to the power box 20, and the two ends of the reset spring are respectively in contact with the hook 31 and the side wall of the power box 20, and the reset spring can keep the hook 31 in the locked position. The reset member 332 provided with the reset spring has the advantages of simple structure and low cost.

[0041] Specifically, when installing the power box 20, first turn the knob 331 to put it in a separated state from the hook 31, and at the same time use the card platform 32 to compress the return spring so that the hook 31 is first switched to the unlocked position, and then use the elastic force of the return spring to move the hook 31 to the locked position, so that the hook 31 and the card platform 32 are engaged with each other.
