Abstract
The invention discloses constitutionally stable display screen cover, including pcb board and mask, lamp bead is provided with described pcb board, fixing hole is provided with described pcb board and mask, buckle is provided with described lamp bead side, clamping lamp bead and the hole clipping of buckle are provided with described mask, not only Stability Analysis of Structures is reliable for it, and installation effectiveness is high.
Description
Technical field
The present invention relates to display screen technology field, in particular it relates to constitutionally stable display screen cover.
Background technology
With scientific and technological constantly development and progress, electronic product and electronic building brick have increasingly been towards compact trend hair
Exhibition.But significantly improve and lifted in material and technical breakthrough, the luminous efficiency of light emitting diode in recent years, very
The brightness for the conventional illumination device that can extremely match in excellence or beauty, therefore it has the trend for gradually substituting existing lighting apparatus.
Present LED display is applied in increasing occasion, it has also become the outstanding person of display industry at present, and
The application of large-scale outdoor LED display screen is more and more extensive.LED display includes mask and lamp plate, and lamp bead is welded on pcb board,
Mask is screwed in pcb board and provides protection for lamp bead.Existing LED display, so that resolution ratio is 30*30 as an example, adopt
With 30*30 lamp bead, it is necessary to mask is fixed using 25 screws, not only efficiency is low when mounted；And if there is collision, squeeze
Pressure or other actions, mask is collided, and extruding is easy to fall off, and its structure is unreliable.
The content of the invention
In order to solve the above-mentioned technical problem the present invention provides constitutionally stable display screen cover, not only Stability Analysis of Structures can for it
Lean on, and installation effectiveness is high.
Technical scheme is used by the present invention solves the above problems：
Constitutionally stable display screen cover, including pcb board and mask, lamp bead is provided with described pcb board, it is described
Fixing hole is provided with pcb board and mask, buckle is provided with described lamp bead side, clamping lamp is provided with described mask
Pearl and the hole clipping of buckle.
The present invention improves on the basis of existing technology, lamp bead squarely, buckle, mask is set on the side of lamp bead
When on pcb board, first, mask is fixed buckle, secondly, recycles fixing device that fixing hole is fixed.
Because buckle has fixation to mask, and fixation is strong, and the quantity of the fixing hole of setting is accordingly reduced.During installation, first
Mask is buckled on pcb board by buckle, it is convenient and simple, then the fixing device of only a few is installed, its installation effectiveness is high.Buckle adds
The structure of fixing device so that its structure is more stable, and mask is not easy to be squeezed out, the stability enhancing of structure.Mask is fixed on PCB
When on plate, mask should flush with the surface of lamp bead, therefore use existing structure, in order to ensure the stability of face mask structure and face
Cover flushes with lamp bead surface, need to carry out multiple spot to mask and fix, therefore need multiple fixing devices.Using the knot of the buckle of this programme
Structure, both mask can be fixed for it, can reduce the quantity of fixing device again, also can effectively ensure that mask is neat with lamp bead
It is flat, avoid mask from protruding from lamp bead.
Preferably, described fixing hole is screw.Secondary fixation is carried out to mask using screw, it is easy to operation.
Preferably, described fixing hole has 9.
Further, in order to strengthen the stability of mask fixation, described fixing hole is separately positioned on four of pcb board
On the center at angle, the center on each side and pcb board.
Preferably, be provided with buckle in order to strengthen the stability of mask fixation, on two sides of described lamp bead, and this two
While it is corresponding sides.
To sum up, the beneficial effects of the invention are as follows：
1st, the fixed form installation effectiveness height of dual fixed form, not only buckle that the present invention passes through buckle and screw, and
The quantity of screw is effectively reduced, greatly improves installation effectiveness.
2nd, the present invention can effectively be improved the stability of mask fixation, be carried using the dual fixed form of buckle and screw
High integrally-built reliability.
3rd, mask is fixed using the structure of buckle by the present invention, and it can effectively ensure that mask flushes with lamp bead, keep away
Exempt from mask and protrude from lamp bead.
Brief description of the drawings
Fig. 1 is the structural representation of the pcb board of the present invention.
Fig. 2 is the structural representation of the mask of the present invention.
Fig. 3 is the enlarged drawing in A portions in Fig. 2.
Mark and corresponding parts title in accompanying drawing：1st, pcb board；2nd, mask；3rd, lamp bead；4th, buckle；5th, fixing hole.
Embodiment
With reference to embodiment and accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described, shown
So, described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.Based on the implementation in the present invention
Example, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made, is belonged to
The scope of protection of the invention.
Embodiment 1：
Constitutionally stable display screen cover as shown in Figure 1 to Figure 3, including pcb board 1 and mask 2, on described pcb board 1
Lamp bead 3 is provided with, fixing hole 5 is provided with described pcb board 1 and mask 2, buckle 4 is provided with the described side of lamp bead 3,
Clamping lamp bead 3 and the hole clipping of buckle 4 are provided with described mask 2.
During installation, mask and pcb board are alignd, will be stuck in corresponding to hole clipping on buckle, then fixing device is fixed on admittedly
Determine in hole, mask is fixed as a result of buckle, the fixing device of use greatly reduces accordingly, and it installs effect
Rate greatly improves.
Fixing hole 5 can use screw, carry out secondary fixation to mask using screw, its is easy to operation.
Embodiment 2：
Constitutionally stable display screen cover as shown in Figure 1 to Figure 3, the present embodiment are preferred on the basis of above-described embodiment
One group of embodiment, still so that resolution ratio is 30*30 as an example, buckle 4 is set, using buckle to mask on each side of lamp bead 3
It is fixed, now, the quantity of fixing hole can effectively be reduced to 9, i.e., can be realized using 9 screws and mask is consolidated
It is fixed.In order to strengthen the stability of mask fixation, fixing hole 5 is separately positioned on four angles of pcb board 1, the center on each side and pcb board
On 1 center, i.e. 9 fixing holes into 3*3 array arrange.
Embodiment 3：
Constitutionally stable display screen cover as shown in Figure 1 to Figure 3, buckle cover over there progress it is tentatively fixed when, in order to
Effective guarantee mask flushes with lamp bead, and the present embodiment optimizes on the basis of above-described embodiment, i.e. two sides in lamp bead 3
On be respectively provided with buckle, and the both sides are corresponding sides.
As described above, it can preferably realize the present invention.
