Abstract
The utility model discloses a splicing structure for one row multiple column large screen projection display wall, belonging to the technical field of large screen projection display industry. The utility model is mainly composed of a screen fixing device and a light dividing board elastic sliding device two parts. The screen fixing device is composed of a screen frame, an adjustable fixing block, and a hard projection screen. The screen fixing device realizes the connection of the screen and the screen frame via the adjustable fixing block which is connected with the screen. The light dividing board elastic sliding device is composed of an elastic jacket, an adjusting rod, a supporting wheel, a sliding bracket, and a light dividing board. The bracket is connected with the light dividing board; the light dividing board is connected with the screen. The light dividing board is in a suspended state. When the shape and size of the screen changes, the light dividing board moves simultaneously with the screen, making the splicing seam of the screen maintain in the state of thin seam. When the environment temperature and humidity change in a certain range, the utility model can maintain the well thin seam splicing and the flatness of the screen, and increasing the reliability and safety of the splicing structure simultaneously.
Description
Technical field
The utility model belongs to large screen projection display industry technical field, particularly a kind of delegation multiple row large screen projection display wall splicing construction.
Background technology
General large screen projection display wall splicing construction is made up of basic building blocks such as hard projection screen, screen frame, beam-splitters.
The basic material of hard projection screen is made up of optical grade Acrylic (acrylic acid) resin, and its linear expansion coefficient is than the big approximately order of magnitude of metal material.Generally, 10 ℃ of the every risings of environment temperature, the size of rear-projection curtain can expand 1 ‰/every meter, relative humidity is increased at 100% o'clock from 60%, the size of rear-projection curtain can expand 2 ‰/every meter, when temperature and relative humidity were returned to original state, the size of rear-projection curtain can return to original size gradually.And the amplitude of variation of the environment temperature under the actual conditions can reach tens of degrees centigrade, and accumulative total numerical value can reach several millimeters more than, especially for jumbotron (diagonal line is 100 " more than).
Large screen projection display wall splicing construction is mostly very strict to site environment temperature, humidity requirement at present.The environment for use humiture is lower than original installation environment humiture, and piece is variable big; Be higher than original installation humiture screen and easily cause distortion again, environment for use only under the state of constant temperature, constant humidity, can keep the original installation effect of screen.Therefore, for developing out delegation's multiple row large screen projection display wall splicing construction that a kind of humiture that conforms changes, be very necessary.
Summary of the invention
The purpose of this utility model: in order to overcome the influence that changed by environment temperature, humidity after screen is installed, a kind of delegation multiple row large screen projection display wall splicing construction is provided, this splicing construction can make giant-screen under different temperatures, humidity environment, remain the long-time stability of screen planarization and splicing construction, make splicing construction can support the finedraw splicing, when environment temperature, humidity change in certain scope, the flatness that still can keep splicing of good finedraw and screen, the reliability and the security that improve splicing construction simultaneously.
To achieve these goals, the utility model relies on following technical proposals to realize:
A kind of delegation multiple row large screen projection display wall splicing construction, mainly formed by screen fixture and two parts of beam-splitter Elastic Sliding device, it is characterized in that: described screen fixture, by screen frame, adjustable whole fixed block and hard projection screen are formed, screen fixture is to realize that by adjustable whole fixed block screen is connected with screen frame, the xsect of framework is a square, there is rectangular enclosure inside, in the square inboard notch is arranged, front surface has the dip plane, adjustable whole fixed block is installed in the notch, screen is connected with adjustable whole fixed block, and screen is dangled in framework, adjusts the verticality of giant-screen piece and the flatness of screen by adjustable whole fixed block, splice with the finedraw that has guaranteed screen, and controlled the hooking that produces because of deadweight effectively.
Described beam-splitter Elastic Sliding device, formed by resilient sleeve, adjusting lever, support wheel, slipper bracket, beam-splitter, there is inverted T-slot beam-splitter Elastic Sliding device carriage inboard, support wheel, adjusting lever are installed in the inverted T-slot, resilient sleeve is installed on the adjusting lever, carriage is connected with beam-splitter, and beam-splitter is connected with screen.Beam-splitter is in suspended state, and when screen physical dimension changed, beam-splitter and screen moved simultaneously, makes the screen edge joint position still keep the finedraw state, and the planarization of screen still remains unchanged.
The beneficial effects of the utility model:
The utility model can effectively prevent the geometry deformation of screen behind the large-screen splicing, can keep good finedraw splicing.Simultaneously the environment for use temperature, when humidity changes within the specific limits, still guarantee the planarization of Mosaic screen, splicing construction is reliable, safety.This utility model is simple in structure, and good manufacturability is easily manufactured.

Embodiment
Below provide embodiment of the present utility model by Fig. 1, Fig. 2 and Fig. 3: a kind of delegation multiple row large screen projection display wall splicing construction, mainly formed by screen fixture 1 and 2 two parts of beam-splitter Elastic Sliding device, this splicing construction assembling sequence is as follows: by shown in Figure 2, screen fixture 1 is made up of screen frame 1-1, adjustable whole fixed block and 1-2, hard projection screen 1-3.Screen fixture 1 is to realize that by adjustable whole fixed block 1-2 screen 1-3 is connected with screen frame 1-1, screen frame 1-1 is made by custom-designed aluminium, the xsect of aluminium framework is a square, there is rectangular enclosure inside, in the square inboard notch is arranged, front surface has the dip plane, and adjustable whole fixed block is installed in the notch; Screen is connected with adjustable whole fixed block, and screen is dangled in framework, adjusts the verticality of giant-screen piece and the flatness of screen by adjustable whole fixed block, splices with the finedraw that has guaranteed screen, and has controlled the hooking that produces because of deadweight effectively.
By shown in Figure 3, beam-splitter Elastic Sliding device 2 is made up of resilient sleeve 2-1, adjusting lever 2-2, support wheel 2-3, slipper bracket 2-4, beam-splitter 2-5.There is inverted T-slot beam-splitter Elastic Sliding device carriage inboard, and support wheel, adjusting lever are installed in the inverted T-slot, and resilient sleeve is installed on the adjusting lever, and carriage is connected with beam-splitter, and beam-splitter is connected with screen.
After screen fixture 1 was finished with 2 assemblings of beam-splitter Elastic Sliding device, screen wherein was connected with the beam-splitter part.Beam-splitter is in suspended state, and when screen physical dimension changed, beam-splitter and screen moved simultaneously, makes the screen edge joint position still keep the finedraw state, and the planarization of screen still remains unchanged.Promptly constitute delegation's multiple row large screen projection display wall splicing construction.
