[0027] Specifically, two bosses 331 are provided on the inner side of the middle of the hook lock member 33, and the facing sides of the two bosses 331 are provided with through holes for passing the pin 36, and the torsion spring 35 is sleeved in the middle of the pin 36. After passing through the bosses 331, the pin 36 is fixed to the button lock assembly plate 34.

[0028] More specifically, one end of the spring wire of the torsion spring 35 abuts against the inner side of the hook lock member 33, and the other end abuts against the inner side of the button lock assembly plate 34, thereby providing reset for the hook lock member 33. The torsion spring 35 is located between the two protrusions 331.

[0029] Specifically, the power box 1 is provided with a first avoidance space 11 at a position corresponding to the push button 31 to provide a movable space for the push button 31 .

[0030] Specifically, the power box 1 is provided with a second avoidance space 12 corresponding to the position of the hook lock member 33 to provide a movable space for the hook lock member 33 .

[0031] Specifically, a tail hook 332 is provided at the bottom of the hook lock member 33 , and a tail hook hanging portion 21 is provided at a position corresponding to the tail hook 332 of the box frame 2 , and the tail hook 332 is buckled with the tail hook hanging portion 21 .

[0032] In some specific embodiments, the push button 31 is pressed down, and the push button 31 rotates in the first avoidance space 11. Under the action of the torsion spring 35, the tail hook 332 is driven to rotate in the second avoidance space 12 in a direction away from the tail hook hanging portion 21, and the tail hook 332 is disengaged from the tail hook hanging portion 21. At this time, the display screen power box 3 lock is in an unlocked state; to switch from the unlocked state to the locked state, it is only necessary to release the pressing of the push button 31, and the tail hook 332 is reset under the action of the torsion spring 35. The tail hook 332 is engaged with the tail hook hanging portion 21 to engage the hook lock 33 with the box frame 2. After engagement, the tail hook 332 is fixed on the box frame 2. At this time, the display screen power box lock 3 is in a locked state. Therefore, this display screen power box lock 3 can be quickly disassembled and assembled, is efficient and labor-saving, and is convenient and quick to operate.

[0033] In some specific embodiments, the tail hook hanging portion 21 is in the shape of a double claw, which is the preferred shape considering both processing and firmness. A more firm multi-claw shape may also be adopted depending on the situation.

[0034] Specifically, the upper display screen power box lock and the lower display screen power box lock are symmetrically distributed in the middle of the upper and lower ends of the power box 1.

[0035] More specifically, the button lock assembly plate 34 has a fastener connection hole 341, and the button lock assembly plate 34 is connected to the power box 1 through the fastener connection hole 341. The two ends of the button lock assembly plate 34 have a protruding end seat 342, and the two protruding end seats 342 are respectively provided with mounting holes.
