Abstract
The utility model provides a modular type projection box body in order to overcome the disadvantages existing in the prior projection box body that the volume is large, the transportation is inconvenient, and the time for the assembly and the disassembly is long. The modular type projection box body of the utility model adopts the technology proposal as follows: the modular type projection box body comprises a first frame and a second frame, which is characterized in that both first frame and second frame adopt a hollow frame-shaped structure, the appearance size of the second frame is smaller than the inner side size of the first frame, the hollow surfaces of the two frames are relative, and the two frames are fixed and connected. The modular type projection box body of the utility model has the advantages of easy transportation and convenient and rapid on-site assembly and disassembly.
Description
Technical field
The utility model relates to the casing that is applied to large screen display, is specifically related to a kind of modular Projection box.
Background technology
People can be spliced into a display wall with a plurality of display units usually according to demand when using the large screen projection display device at present.The Projection box of forming projection display unit is to be used for fixing projector equipment such as screen, catoptron, projector and six-axial adjustment frame etc., and in addition, Projection box also works to block stray light.In actual installation was used, traditional way was, assembles whole Projection box and transport then when producing, and arrived the use scene and more a plurality of Projection boxs piled up according to demand splicing and install.
Along with the development of display technique, projection screen is increasing, and the Projection box that is used for fixing projector equipment is correspondingly also increasing, makes casing heavier, and it is bigger to take up room, and bothers very much with traditional method transportation, installation.In order to solve the problem of the excessive transportation trouble that causes of volume, usual method is at present, all parts of Projection box are transported to the use scene after, using assembled on site to become Projection box, use the on-the-spot dismounting long defective consuming time of constructing but bring.
The utility model content
The technical problems to be solved in the utility model is in order to overcome the existing above-mentioned shortcoming and defect of present Projection box, a kind of easy transportation, on-the-spot modular Projection box convenient to disassembly to be provided.Modular Projection box described in the utility model is by the following technical solutions: a kind of modular Projection box, comprise first framework and second framework, described first framework and second framework all are the frame type structure of hollow, the physical dimension of second framework is less than the inside dimensions of first framework, the hollow face of two frameworks is relative, and two frame fixation connect.
Described two frame fixation are connected to two base of frame and are bolted to connection.
Described second frame facet upper end also is provided with portable plate.Described portable plate is connected with second frame facet upper end by loose-leaf.The overall height of described second framework and portable plate equates with the height of first framework.
Projection case of the present utility model can use by a cover in use, also can overlap such Projection box more and use jointly, to satisfy the needs of large screen projection.
The utility model is compared with existing Projection box, has following beneficial effect:
1, this Projection box adopts modular design, and on-the-spot easy accessibility, quick has been saved the mounting or dismounting time greatly.
2, all be designed on the length of the second framework outside and the width littler than the size of the first framework inside, when transportation, the portable plate of the second framework both sides can be put down, then second framework is put into first framework, save transport space, efficiently solve the excessive transportation difficult problem that causes of volume of integral structure casing
3, each module adopts standardized designs and processing, has simplified technological process.

Embodiment
The utility model is described in further detail below in conjunction with embodiment, but protection domain of the present utility model is not limited in this.
Embodiment 1
As shown in Figure 1, modular Projection box of the present utility model comprises first framework 1 and second framework 2, described first framework 1 and second framework 2 all are the frame type structure of hollow, the physical dimension of second framework 2 is less than the inside dimensions of first framework 1, the hollow face of two frameworks is relative, and the bottom is bolted to connection.
Described second frame facet upper end also is provided with portable plate 3.Described portable plate 3 is connected with second frame facet upper end by loose-leaf 4.The overall height of described second framework 2 and portable plate 3 equates with the height of first framework 1.
Fig. 2 is that as seen from Figure 2, behind the both sides portable plate 3 that puts down second framework, second framework 2 places in first framework 1 fully at the laying state figure of when transportation modular Projection box, and then with bolt with two frame fixation, thereby saved transport space greatly.
Fig. 3 is the first framed structure synoptic diagram of present embodiment, Fig. 4 is the second framed structure synoptic diagram of present embodiment, after second framework shown in Figure 4 placed first framework shown in Figure 3, two frame fixation are connected the modular Projection box that promptly gets present embodiment with bolt.
Claims (5)
1, a kind of modular Projection box comprises first framework and second framework, it is characterized in that, described first framework and second framework all are the frame type structure of hollow, the physical dimension of second framework is less than the inside dimensions of first framework, and the hollow face of two frameworks is relative, and two frame fixation connect.
2, a kind of modular Projection box according to claim 1 is characterized in that, described two frame fixation are connected to two base of frame and are bolted to connection.
