Description
Technical field
The present invention relates to screen assembling technique field, particularly a kind of screen floating installation.
Background technology
In actual applications, the giant-screen of multi-display apparatus is generally assembled by the screen of many unit, as Fig. 1 or shown in Figure 2.Shown in Figure 1 is the Facad structure of multi-display apparatus commonly used, and shown in Figure 2 is the side structure of multi-display apparatus commonly used, and it is made of a horizontal M screen and vertical N screen, and what have may also be furnished with a base in the bottom.Among the figure, 1 is piece, and 2 is single screen, 3 is base, by seeing among the figure, the rear of screen is provided with supporting mechanism 4 and projector 5 respectively, and wherein supporting mechanism 4 can be that the giant-screen that corresponding one of each screen, one of a plurality of screen correspondence or all screens are formed uses one jointly.
Multi-display apparatus is made up of many identical elementary cells, and these elementary cells are stacked and/or together placed side by side by the mode of module.Elementary cell (all or part of) with this specific character comprises light shielding part, supporting mechanism 4, screen 2 and projector 5.These screens 2 can be to be installed on the supporting mechanism 4 regularly or movably.Projector 5 (all or part of) is installed in 4 li of supporting mechanisms in advance.Yet this installation process of elementary cell need be carried out on a stable and smooth stayed surface, to guarantee the best combination between the elementary cell.Simultaneously, when climate change (as variation of temperature and relative humidity etc.), may change the distance between the elementary cell, to the negative effect that is combined with between the elementary cell.
Shown in Fig. 3 a, 3b, 3c and 3d, three screens 2 and three supporting mechanisms 4 are installed together by stacked mode, and under climate effect, the size that different expansion coefficient can cause screen 2 changes with respect to the size of supporting mechanism 4.In order clearly to describe this change in size difference, among the figure screen 2 and supporting mechanism 4 are shown respectively.Fig. 3 a is correct screen 2 and the supporting mechanism of installing 4 under the normal climate condition.Compare with Fig. 3 a, Fig. 3 b and Fig. 3 c are the situations under climate effect, and the size of screen 2 is with respect to the size decreases of supporting mechanism 4.In Fig. 3 b, three screens 2 no longer combine, and the piece 1 between adjacent two screens 2 becomes big.In Fig. 3 c, three screens 2 still combine, and piece 1 does not change basically, but the screen total body surface area has diminished.Compare with Fig. 3 a, because climate change, it is big that the size of the relative supporting mechanism 4 of size of the screen 2 among Fig. 3 d becomes, and piece 2 does not change basically, but the screen total surface area becomes big.The variation of the screen that this stack is installed among Fig. 3 also may occur in the screen of installing side by side.This climate change can produce material impact to the multiscreen display apparatus that is assemblied to form by a plurality of elementary cells, influences the display quality of giant-screen easily, and also have following problem simultaneously: the edge of single elementary cell is frangible in transportation.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of screen floating installation be provided, this device can realize screen about, about and move forward and backward, eliminate the piece between adjacent two screens to greatest extent.
The present invention is achieved through the following technical solutions, and a kind of screen floating installation comprises at least two bracing frames, and each bracing frame is located at rear-projection case both sides respectively and is fixedlyed connected with screen sides; Each bracing frame is respectively equipped with rotating unit, and rotating unit comprises turning axle and tumbler, and turning axle is connected with screen by tumbler, and turning axle is connected with the rear-projection case by axle bed.

Cam adjustment construction package is set the joint at two ends respectively up and down with axle bed on the described rear-projection case, two ends are provided with the radial compression assembly perpendicular to turning axle respectively about the axle bed.
Described each bracing frame also comprises the unit that moves axially of realizing that screen moves up and down, and moves axially the unit and comprises axial compression assembly and setting nut, and the axial compression assembly is placed in the turning axle bottom, and the turning axle bottom is provided with setting nut.
Described axial compression assembly comprises axle spring and setscrew nut, and axle spring is located at the setting nut top, and setscrew nut is located at the axle spring top.
Regulate for convenience, described setting nut is the knurled nut.
Described turning axle and tumbler can be integral structure, and tumbler is the fixed block that is fixed on the turning axle, and with the rotation of turning axle, tumbler is and then rotation also, rotates thereby drive screen.
Described turning axle and tumbler also can be split-type structural, and tumbler is the hinge hook, and the hinge hook comprises fixed part and hook portion, and fixed part is connected by hinge axis with hook portion, and hook portion is connected with turning axle, and fixed part is fixedlyed connected with screen.
When this screen floating installation uses, according to actual needs the screen position of each elementary cell is regulated.When screen need move forward and backward, move radially the unit by adjusting and realize, rotating cam is adjusted construction package, and radial spring can be drawn high or be compressed in the radial compression assembly, thereby drives whole bracing frame and screen moves forward or backward; When screen needs left rotation and right rotation, realize by regulating rotating unit, rotate turning axle, tumbler drives screen and realizes left rotation and right rotation, simultaneously, when turning axle and tumbler are split-type structural and tumbler when being the hinge hook, screen itself also can be with respect to the bracing frame left rotation and right rotation, when a plurality of screen splicing, this anglec of rotation can realize the arc splicing of screen; When screen need move up and down, realize to mobile unit by regulating shaft, the rotation setting nut, axle spring can be compressed or stretch, and the driven rotary axle rises or descends, and moves up or down thereby drive screen.
When this screen floating installation is applied to a plurality of screen splicing, can adopt the spring nail assembly identical that adjacent two screens are connected, so both can control the piece between the screen preferably, also can make the fixing splicing of a plurality of screens with the radial compression modular construction.
The present invention has following beneficial effect with respect to prior art:
When this screen floating installation uses, can make two adjacent screens combine closely mutually, the piece between the screen has been realized minimizing, and reaches the piece size less than 0.5 millimeter.When using the spring nail assembly to clamp a plurality of screens are fixed together, can guarantee that piece can keep minimum always, not be subjected to the influence of manufacturing tolerance or climate change (as the variation of temperature and relative humidity etc.).
In this screen floating installation, because bracing frame and rear-projection case have a movably point of fixity, by adjusting cam adjustment construction package is removable this point of fixity, and the effect of radial compression assembly also can be in the limited range internal strain guaranteeing the minimum piece combination between the screen, thereby the difference of the expansion rate between screen and the supporting construction can be compensated.Therefore, screen can carry out moving (promptly move forward and backward, move up and down or left rotation and right rotation) in the certain limit on bracing frame, so just reaches the minimized purpose of piece.
