In some embodiments, as shown in fig. 1 and fig. 2, a receiving groove 103 is formed in the power supply box 12, the quick locking structure 13 is fixed in the receiving groove 103, and the receiving groove 103 can be used for fixing a control system and/or a signal transmission system. When the power supply box 12 is disassembled, the quick locking structure 13 and the components inside the power supply box 12 for realizing the synchronous disassembly of the power supply control system and/or the signal transmission system can be conveniently repaired and replaced for the control system and/or the signal transmission system inside the power supply box 12.
In an example, the power supply box 12 is provided with a through hole 104 penetrating through the power supply box 12, and the quick locking structure 13 is fixed in the accommodating groove 103, so that the space inside the power supply box 12 can be optimized and the whole volume of the power supply box 12 can be reduced under the condition that the use of the quick locking structure 13 is not affected. Meanwhile, the handle 131 is partially exposed from the through hole 104, and when the handle 131 is pressed, the handle 131 moves in the power supply box 12 in a direction away from the through hole 104 to an open position, so that the power supply box 12 and the control system and/or the signal transmission system in the power supply box 12 can be detached together.
In some embodiments, the power supply box 12 includes a first fixing plate 122 and a second fixing plate 123 connected between the third positioning block 12c and the fourth positioning block 12d, wherein inner surfaces and outer surfaces of the first fixing plate 122 and the second fixing plate 123 are respectively a groove wall of the accommodating groove 103 and an outer surface of the power supply box 12.
Illustratively, the first fixing plate 122 is vertically connected to the second fixing plate 123, and the locking seat 133 of the quick-locking structure 13 is fixedly connected to the second fixing plate 123 through the shaft hole. The first fixing plate 122 and the second mounting portion 112 are spaced to form an operating space, the through hole 104 is formed in the first fixing plate 122, the handle 131 is exposed from the through hole 104, the second fixing plate 123 is provided with an avoiding notch, the avoiding notch is arranged corresponding to the second clamping groove 102, and the locking end of the locking tongue 132 of the quick locking structure 13 can extend into the second clamping groove 102 from the avoiding notch.
In some embodiments, as shown in fig. 1, 2 and 6, the handle 131 includes a position-limiting plate 1311, an operation plate 1312 and a connecting plate, the operation plate 1312 is fixedly connected to the position-limiting plate 1311, both the position-limiting plate 1311 and the operation plate 1312 are fixedly connected to the connecting plate, and the connecting plate is connected to the latch 132 and movably connected to the lock seat 133; the area of the stop plate 1311 is larger than the areas of the operation plate 1312 and the through hole 104, when the handle 131 is in the locking position, the operation plate 1312 can be located in the through hole 104 for the user to press, and the stop plate 1311 can abut against the first fixing plate 122 and/or the second fixing plate 123 to prevent the handle 131 from moving excessively.
In some embodiments, the quick-locking structure 13 further includes an elastic member, and a mounting groove is formed in the lock seat 133; the two ends of the elastic member are respectively connected between the connection end of the latch bolt 132 and the groove wall of the mounting groove.
It can be understood that when the handle 131 moves to the open position, the elastic member elastically deforms, the locking end of the locking tongue 132 moves out of the second locking slot 102 and is located in the mounting slot, and at this time, the power supply box 12 can be taken out of the box body frame 11; when the handle 131 moves to the locking position, the locking end of the locking tongue 132 is at least partially located in the second locking groove 102, and at this time, the power supply box 12 is fixed on the box body frame 11.
In some embodiments, the elastic member includes a first spring and a second spring, and the first spring and the second spring are uniformly distributed on the connection end of the locking tongue 132, so that the locking tongue 132 can be uniformly stressed. Meanwhile, two limiting grooves are formed in the groove bottom of the mounting groove in a recessed mode, and the two limiting grooves are arranged at intervals respectively. When the user moves the handle 131 to the open position, one end of the first spring and one end of the second spring abut against the groove wall of the mounting groove, and at the moment, the first spring and the second spring are elastically compressed along the groove wall of the limiting groove; when the user releases the handle 131, the first spring and the second spring restore along the groove wall of the limiting groove, and then elastically stretch, so that the handle 131 automatically moves to the locking position, and the locking end of the locking tongue 132 moves into the second locking groove 102. After the handle 131 is moved to the locking position, the first spring and the second spring may not completely recover their deformation, that is, the first spring and the second spring still keep the elastic expansion trend, and when the length of the locking tongue 132 is equal to or greater than the depth of the second slot 102, the locking end of the locking tongue 132 can be ensured to always abut against the inside of the second slot 102, so as to prevent the locking tongue 132 from loosening and shaking; of course, the elastic member may be completely deformed after the handle 131 is moved to the locking position.
In some embodiments, a mounting plate 14 is secured to a back plate 15 of the display screen housing. Wherein, power pack 12 realizes detachable the connection through a plurality of axostylus axostyles and shaft hole cooperation with mounting panel 14, and mounting panel 14 accessible bolt fixed connection is on backplate 15. After the power supply box 12 and the mounting plate 14 are installed, the mounting plate 14 can cover the accommodating groove 103, so that the mounting plate 14 can enhance the stability of the power supply box 12 on the box frame 11, and can also play a certain sealing role on the accommodating groove 103 of the power supply box 12 to prevent impurities such as dust from entering the power supply box 12, and further prevent the components in the power supply box 12 from being damaged.
Optionally, the mounting plate 14 is provided with a plurality of via holes 105 penetrating through the mounting plate 14, and the via holes 105 facilitate the conductive connection between the control system and/or the signal transmission system and the display module in the display screen box.
