When installing LED display cabinet, prepares several LED display framves 6 and several be eccentrically rotated connector.By two
The sideline of LED display frame 6 is drawn close, and by 31 rotating eccentricity wheel 3 of handle, the block 21 of 2 bottom of connecting rod is made to be moved to groove 51
Interior, a card slot 11 by that will be eccentrically rotated connector blocks the fixed link 7 of one of LED display frame 6.Two clamping blocks
4 can draw close during card slot 11 blocks fixed link 7 to connecting rod 2.Then rotating eccentricity rotary connector makes another card slot
11 block the fixed frame 7 of another LED display frame 6, again by 31 rotating eccentricity wheel 3 of handle, make the block of 2 bottom of connecting rod
21 is mobile to the direction far from groove 51, and clamping block 4 is finally made to block fixed link 7, is realized jointly by clamping block 4 and card slot 11
Locking and positioning are realized to fixed link 7, simultaneously as clamping block 4 is equipped with chamfering inclined-plane 1, block fixation in card slot 11
Have the function of flexible buffer during bar 7, it is same with slow after card slot 11 and clamping block 4 are locked bar 7 jointly
The effect of punching and positioning, and can be realized the accurate locking to two LED display framves 6.The assembly of two LED display framves 6 is
It completes, it is then successively that remaining LED display frame 6 is successively assembled according to the method described above.
Disassembly:
After LED display frame 6 is assembled into LED display cabinet by being eccentrically rotated connector, when disassembly is desired, lead to
31 rotating eccentricity wheel 3 of handle is crossed, makes the block 21 of 2 bottom of connecting rod to close to the movement of the direction of groove 51.It is revolved by rotating eccentricity
Turning connector, exits one of card slot 11 from fixed link 7, the LED display frame 6 of two adjacent connections separates,
A card slot 11 is exited from another fixed link 7 again, and will be eccentrically rotated under connector dismantles from LED display frame
Come.Finally, successively remaining assembled connected LED display frame 6 is disassembled by the above method.
Technical solution disclosed in the present embodiment can be realized single dismounting, and precision when locking is high, easy to operate.
The above description is only a preferred embodiment of the present invention, is not intended to limit the scope of the invention, all at this
Under the inventive concept of invention, using equivalent structure transformation made by description of the invention and accompanying drawing content, or directly/use indirectly
It is included in other related technical areas in scope of patent protection of the invention.
