【Technical field】
The present invention relates to display screen mounting technique field, and in particular to a kind of display screen unit and use the display screen unit
Display screen install module.
【Background technology】
Fast-developing and commonly used with LED display technology, public place and various performance stages etc. all start
Using resolution ratio is higher, moulding is more enriched, show that area bigger, more frivolous, color rendering effect more preferably big screen LED shows
Display screen.
The display screen of existing sheet metal box body and die casting aluminium casing, due to being subject to processing the limitation of technique, generally by its structure
It is designed to be only suitable for plane assembly or the single curved surface assembling and molding of shape, in other words, otherwise existing display screen unit is only
Adapt to be assembled into flat-faced screen in plane, otherwise can only be adapted to curved surface is assembled into camber display screen, it is impossible to and realization both may be used
Plane it is assembled again can a variety of moulding curved surface or arc splicing structure or three-dimensional splicing structure, and be currently used for camber display screen
Gap between the two neighboring camber display screen unit of assembling is big, and existing camber display screen unit is first by casing
Curved surface is made in front, is then gone to be spliced to together with connector, therefore can not adjust the curvature of camber display screen as needed, and
Excessively high etc. reason of camber display screen unit making and installation difficulty, cost can not meet market demands.The structure of single moulding,
The stage demand of current three-dimensional display effect can not be met, the application of LED display is limited.
In the market occurs in that some display screen units can realize the assembled pattern of curved surface, but such product it is assembled not
With shape when need different connector or body structure to coordinate, not only add production cost, and transport, store not
The technical problem such as convenient.For example, the patent No.：201310095999.8, title：It is a kind of can plane and curved surface assembling LED show
The patent document of screen unit disclose it is a kind of can plane and curved surface display screen.Can plane and curved surface assembling LED display list

The location structure 65 also includes the shank 657 being fixedly arranged in the receiving space 65A, and the locating piece 652 is remote
Surface from the positioning step 33 is additionally provided with projection 658, and the two ends of the spring 653 are sheathed on the He of shank 657 respectively
Described raised 658.
2nd, the location structure 65 includes the spring 651' being fixedly arranged on the positioning step 33 and is contained in the installation
Locating ring 653', the spring 651' in hole 31 support the locating ring 653' to cause the locating ring 653' and the rotation
Button 62 is adjacent to, and relative displacement occurs for the locating ring 653' and the knob 62 under external force.
In order to ensure that when the latch part 61 and 63 clamping of hook part, the knob 62 is kept in the case where being acted on without external force
The reliability of geo-stationary, can also be respectively equipped with phase interworking on the locating ring 653' and the opposite surface of the knob 62
The projection and groove of conjunction.
The present invention also provides a kind of display screen and installs module, and the display screen, which installs module, includes mounting bracket and at least two
Display screen unit 100 any one of above-mentioned.Each display screen unit 100 passes through each display screen unit respectively
Fixing device 23 in 100 is perpendicularly fixed on the mounting bracket.Wherein, the mounting bracket is engraved structure, and the display
After screen unit 100 is fixed on the mounting bracket, and the bonnet 3 of each display screen unit 100 is contained in hollow out described in one
In structure, so as to be conducive to reducing the integral thickness that the display screen installs module.
Figure 13 is referred to, is the structural representation of the splicing of display screen unit anisotropic approach shown in Fig. 1.Multiple display screens
Unit 100 is spliced to form an annular first screen A and at least two display screen units 100 described in totally one and curved second
Screen B, the second screen B end described at least two is connected with the first screen A respectively.
Figure 14 is referred to, is the structural representation of the splicing of display screen unit right angle shown in Fig. 1.When the display screen unit
The angle of chamfering structure described in 100 is 20 ° -45 °, and the display panel 1 in display screen unit 100 described at least two can
At right angles to splice.It is preferred that, the angle of the chamfering structure is 45 °.
Display screen unit and existed using the beneficial effect of the display screen installation module of the display screen unit that the present invention is provided
In：
First, by setting the fixing device 23 and the side 22 and first table on the second surface 21
Face forms chamfering structure, so that each display screen unit 100 can be respectively by each display screen unit 100
The fixing device 23 is perpendicularly fixed on the mounting bracket, and can realize the seamless connection of the display panel 1 and straight
Angle and the assembly of polymorphic structure display screen, not only avoid product needed in assembled different shape different connector or
Body structure coordinates, and avoids the structure directly caused using display module assembly formation right angle and polymorphic structure display screen
The problem of complicated and specialty requires high.
2nd, by the way that the positioning side 26, the handle portion 27 and the bonnet 3 are arranged to, the upper any point difference of three
Line to the first surface outline is not more than the folder of the chamfering structure with the maximum angle of first surface formation
Angle, it is ensured that under conditions of the angle value of the same chamfering structure, increases the splicing angle of the display screen unit 100
Scope.
3rd, by the way that magnetic element is set into permanent magnet, it can not only avoid increasing circuit, and increase can be avoided to protect
Protection circuit or protection device are to prevent from occurring under circuit powering-off state the problem of display screen unit 100 falls.
4th, the permanent magnet 232 is fixed by setting the fixed column 231 can be not only used for, can also be to the permanent magnetism
Body 232 plays a protective role, and prevents that the permanent magnet 232 from being acted on and fragmentation in transport and installation process by external force.
5th, by setting multiple connections between the lateral surface of the connecting pole 235 and the host cavity 23A medial surface
Muscle 236, can strengthen the intensity of the fixed column 231.
6th, original connection component is replaced by tin cream welding, not only realizes fixation and electrical connection effect, Er Qieming
The aobvious volume for reducing described control unit 4.The modularized design of control unit can be realized simultaneously so that each display
It is a complete display screen to shield unit, it is possible to achieve the institute of display screen is functional, so that display screen unit is in assembling
With it is more convenient during maintenance, maintenance when only need to close and dismantle problematic display screen unit, so as to ensure
Display screen can also normal work, raising utilization rate when lacking part display screen unit.Further, since the body of described control unit 4
Long-pending reduction, can make it that any point is respectively to the line and first table of the first surface outline on the bonnet 3
The maximum angle that face is formed reduces, so as to be conducive to reducing the minimum value of the angle of the chamfering structure.
Above-described is only embodiments of the present invention, it should be noted here that for one of ordinary skill in the art
For, without departing from the concept of the premise of the invention, improvement can also be made.But these belong to the protection model of the present invention
Enclose.
