Description
Technical field
The present invention relates to display screen technology field, self-locking mechanism is safeguarded before specially a kind of LED display mould group.
Background technique
For LED display as a kind of display equipment, application is more and more extensive.But due to the space of many scenes, convenience
Limitation, it is desirable that LED display has preceding maintenance function.For preceding maintenance, the preceding maintenance of mould group is most importantly realized.
Preceding maintenance for mould group, there are many design methods, and the current most common design method is " maintenance side before magnetic suck
Formula ", basic principle are as follows: the first and second adsorption piece is installed respectively on the mould group back side and box frame, passes through the first and second adsorption piece
Display module is fixed on box frame by magnetic attraction, when disassembly, is greater than first and second using one in the front of mould group and is inhaled
The reaction force of attached power is dismantled mould group, one way in which are as follows: one piece of biggish iron plate is installed simultaneously at the back side of mould group,
In disassembly, using the magnet of a bigger magnetic attraction, mould group front is touched, mould group is removed.
In order to guarantee convenience when disassembly, the design value of the adsorption capacity between the one or two adsorption piece usually will not be too
Greatly, it avoids being needed in disassembly process using excessive reaction force, and is difficult to dismantle mould group.
Existing LED display has the disadvantage in that maintenance mode before magnetic suck, and maximum disadvantage is exactly that mould group is by magnetic
Adsorption capacity is fixed, and is that a kind of non-rigidity is fixed, when shielding body and generating strenuous vibration, rock, collide etc. similar to situation, display module
It is likely to occur the phenomenon that falling off, stability is insufficient, there is very big risk, while can also damage display screen.
For disadvantage mentioned above, if increase other rigidity fixed forms on the basis of magnetic, such as: each module increases
The screw or other modes of preceding fixation, and will affect the convenience of screen body maintenance, it needs first to remove disassembly rigidity fixing piece: as fixed
Then screw is again dismantled mould group, not convenient enough.
Summary of the invention
Present invention solves the technical problem that being maintenance mode before the magnetic suck for overcoming the prior art, maximum disadvantage is just
It is that mould group is fixed by magnetic adsorbability, is that a kind of non-rigidity is fixed, generates strenuous vibration, rocks, collide etc. in screen body similar to feelings
When shape, display module is likely to occur the phenomenon that falling off, and stability is insufficient, there is very big risk, while can also damage display
The problem of screen.
To achieve the above object, the invention provides the following technical scheme: safeguarding before a kind of LED display mould group from lock machine
