Connect, be provided in shaft with the matched locked groove of closing piece, be additionally provided with card slot in the drive sleeve, the card slot is close to drive sleeve
Outer wall, the unlocking tool include handwheel disk, bolt and magnetic steel ingot, and the bolt is set to the lower section of handwheel disk, and size
Match with card slot, the magnetic steel ingot is set to inside bolt, and magnetic repulsion can occur with closing piece.
The working principle of the invention: when needing to open cover, the bolt of unlocking tool being inserted into the card slot of drive sleeve,
Because closing piece is magnet steel, and the magnetic steel ingot of unlocking tool is to repel each other with closing piece magnetism, therefore closing piece can be pushed to be moved to and turn
The locked groove of axis is engaged, and being rotated further by drive sleeve can drive shaft to rotate, so that fixture block rotation be made to be detached from the locking with display screen.When
When not using unlocking tool, closing piece can reset under the action of the spring, and drive sleeve and shaft are not engaged at this time, and drive sleeve is only
It can be dallied in shaft by annular groove, and fixture block rotation can not be made to be detached from the locking with display screen, thus reach protecting effect,
Solving the problems, such as that existing shield is easily artificially deliberately dismantled causes ad display screen to damage.
Further, the card slot is at least two and is arranged along the axisymmetrical of shaft that the groove is at least two
And it is arranged along the axisymmetrical of shaft.
Further, the shaft is set as two and is located at the two sides of cover.
Further, the fixture block is arranged perpendicular to shaft axis and is set in the lower end of shaft.
Further, non-slip mat is provided on the side wall of the groove body.
In conclusion by adopting the above-described technical solution, the beneficial effects of the present invention are:
The present invention in drive sleeve by pacifying by installing shaft on advertisement screen shield and being arranged drive sleeve in shaft
The magnet steel closing piece being slidably connected is filled, when making closing piece and shaft that could open shield when being engaged using dedicated tool, is solved
Existing shield is easily artificially deliberately dismantled the problem of causing ad display screen to damage.
