Preferably, the position limiting structure is multiple along sidewall spacers arrangement, and the fixing component is correspondingly connected in each limitAt structure.
Preferably, each fixing component is by screw connection at each position limiting structure.
Preferably, each fixing component has the pressing plate for stretching out and withholding at antenna plate edge side end back.
Preferably, each position limiting structure includes rectangular side wall, and the fixing component, which has, to be embedded in rectangular side wallFixed plate and the pressing plate being connected with fixed plate, the pressing plate are stretched out across rectangular side wall.
Preferably, the area of the antenna plate is greater than the area of screen assembly, and the position limiting structure is located at the outer of side wallSide.
Used technical solution to solve above-mentioned technical problem: a kind of display, it is solid including above-mentioned electromagnetic screen installationDetermine structure.
The utility model has the advantages that forming pre- leave a blank by the way that side wall is arranged in lid in this electromagnetic screen installation fixed structure and displayBetween screen assembly is embedded in, antenna plate serves as backboard and covers to be fixed at screen assembly back, is recycled and is fixedComponent carries out locking and completes installation, easy to operate, eliminates the components such as traditional center, backboard, simplifies disassembly operation.

Specific embodiment
This part will be described in specific embodiments of the present invention, and the preferred embodiments of the invention is shown in the accompanying drawings, attachedThe effect of figure be with figure remark additionally book word segment description, enable a person to intuitively, visually understand of the inventionEach technical characteristic and overall technical architecture, but it should not be understood as limiting the scope of the invention.
In the description of the present invention, it is to be understood that, be related to orientation description, for example, above and below, front, rear, left and right etc.The orientation or positional relationship of instruction is to be based on the orientation or positional relationship shown in the drawings, and is merely for convenience of the description present invention and letterChange description, rather than the device or element of indication or suggestion meaning must have a particular orientation, with specific orientation construct andOperation, therefore be not considered as limiting the invention.
In the description of the present invention, several to be meant that one or more, it is multiple to be meant that two or more, be greater than,Be less than, more than etc. be interpreted as not including this number, it is above, following, within etc. be interpreted as including this number.If there is being described to first,Second is only intended to for the purpose of distinguishing technical characteristic, is not understood to indicate or imply relative importance or implicitly indicates instituteThe quantity of the technical characteristic of instruction or the precedence relationship for implicitly indicating indicated technical characteristic.
In description of the invention, unless otherwise restricted clearly, the words such as setting, installation, connection be shall be understood in a broad sense, instituteAbove-mentioned word in the present invention specific can rationally be determined with the particular content of combination technology scheme by belonging to technical field technical staffMeaning.
Electromagnetic screen of the present invention installs fixed structure, including lid 10, screen assembly 20, antenna plate 30 and fixing component40, wherein lid 10 is the front cover of display, has rectangular opening in the middle part of lid 10, around opening setting on lid 10Side wall 11, side wall 11 enclose composition reserved space, are embedded in for screen assembly 20, and the size and 20 phase of screen assembly of reserved space are suitableIt answers, is contacted so that the edge side of screen assembly 20 can be supported with corresponding side wall 11, to limit screen assembly 20It moves freely in the horizontal direction, completes the positioning to screen assembly 20, the reserved space that side wall 11 is formed is equivalent in traditionalMount structure can provide screen assembly 20 fixed and play a protective role.
Be alternatively arranged the multiple position limiting structures 12 of setting along the direction of side wall 11 on lid 10, position limiting structure 12 for pairAntenna plate 30 is positioned, and specifically, the stacking of antenna plate 30 is fixed on 20 back of screen assembly, the edge of antenna plate 30Side is supported with each position limiting structure 12 on lid 10 and is contacted, and freely moves in the horizontal direction to also limit antenna plate 30It is dynamic.Position limiting structure 12 includes rectangular side wall 121 and the connecting screw hole 122 that rectangular 121 center of side wall is arranged in, and position limiting structure 12 existsFour direction has arrangement up and down, and particular number selects according to the actual situation, and rectangular side wall 121 withstands antenna plate 30Edge side, four direction moves freely limitation antenna plate 30 up and down.
Each position limiting structure 12 is respectively positioned on the outside of side wall 11, and the size of antenna plate 30 is greater than the ruler of screen assembly 20It is very little, so that the working region of antenna plate 30 is also bigger than screen assembly, the antenna on antenna plate 30 is distributed completely,It not will receive structure size limitation, can have preferable hand-written performance 20 marginal portion of screen assembly yet.In traditional technology byIn Structure Designing Problem, so that screen assembly, antenna plate are all built-in in center, so that antenna plate is because of dimensional problem workIt is smaller to make region, it is difficult to reach good hand-written performance.
The detachable connection fixing component 40 on each position limiting structure 12, fixing component 40 is withheld carries on the back in antenna plate 30Portion, to antenna plate 30 be fixedly mounted, and then screen assembly 20 is fixed, antenna plate 30 itself is by glass fiber materialIt constitutes, structural strength is high, by carrying out thickening processing to antenna plate 30, screen assembly 20 can be fixed on the pre- of lid 10In spacing, specific thickness size selects according to the actual situation.
Wherein, each fixing component 40 includes that bending is connected to form integrated fixed plate 41 and pressing plate 42, and fixed plate 41 is embedded inIt is fixed in rectangular 121 inside of side wall and by screw 43, pressing plate 42 is withheld across the stretching of rectangular side wall 121 on 30 side of antenna plateThe back of edge side is effectively locked antenna plate 30 by each pressing plate 42 on 30 edge side of antenna plate；Moreover,It is designed by 42 fastened structure of pressing plate, can be avoided since the dynamics of screw locking is different, cause fixed space difference.
Electromagnetic handwriting liquid crystal display of the present invention, including electromagnetic screen above-mentioned install fixed structure, are installed by this kindFixed structure can effectively simplify installation and disassembly process.
