Description

Technical Field

[0001] The utility model relates to the technical field of space display screen installation, in particular to a back frame structure for a space display screen. Background Art

[0002] At present, the ultra-high-definition immersive experience space has gradually become a new innovative application scenario for display screens; for example, some 4D cinemas can enable audiences to feel special effects such as wind, rain, lightning, etc. together with the protagonist, for example, to understand history by showing real battlefields, and for example, to truly feel the interior and performance of cars in the space.

[0003] Some immersive experience spaces are essentially in a space building body, and display screens are laid at the positions of each wall, ceiling, and floor; the immersive feature enables the audience to no longer be a bystander but to be fully immersed in it. Through surround sound, realistic tactile feedback, and free interaction methods, the audience feels as if they are in the displayed scene.

[0004] In the actual construction process, many enterprises now directly adopt the method of laying LED display screens on the wall, that is, setting a back frame and installing LED display screen blocks on the back frame. There are usually two ways for the back frame: the first is that multiple rods are welded according to needs and then the welded back frame is fixed on the wall, but this welding method is difficult to ensure the flatness of the front of the back frame; the second is that multiple back frame units are gradually connected into an integrated back frame by bolts and then the back frame is fixed on the wall as the front wall, and this bolt connection method is also difficult to ensure the flatness of the front of the back frame.

[0005] If the flatness of the back frame is not good, when the LED display screen blocks are magnetically adsorbed on the back frame to form a display screen for the entire wall, the flatness of the display screen can only depend on adjusting the magnetic adsorption screws on the back of the LED display screen blocks (adjusting the length of the magnetic adsorption screws on the back of the LED and then making the magnetic adsorption screws adsorb on the back frame); however, the degree of adjustment by this method is limited and still cannot particularly well ensure the flatness of the entire display screen.

[0006] Therefore, the company has improved the structure of the back frame, and can better ensure the flatness of the front of the back frame during the assembly process of the back frame, thereby improving the flatness of the entire display screen. Content of the Utility Model

[0007] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a back frame structure for a space display screen that can adjust the flatness of the front of the side wall frame I / top wall frame II / bottom wall frame III, thereby improving the flatness of the overall display screen and the visual effect of people.

[0008] The object of the present utility model is achieved through the following technical solutions: A back frame structure for a space display screen, including side wall frame Ⅰ, top wall frame Ⅱ, and bottom wall frame Ⅲ, which together form a cuboid space structure;

[0009] The side wall frame Ⅰ, top wall frame Ⅱ, and bottom wall frame Ⅲ are all formed by splicing a plurality of first frame units arranged in an array;

[0010] The first frame unit has a transverse through-hole and a longitudinal through-hole. In the corresponding wall frame, the positions of the transverse through-holes of the first frame units in the same horizontal row are opposite, and are penetrated by the same cross bar. In the corresponding wall, the positions of the longitudinal through-holes of the first frame units in the same vertical row are opposite, and are penetrated by the same longitudinal bar;

[0011] There is a gap in the thickness direction between the cross bar and the transverse through-hole, and between the longitudinal bar and the longitudinal through-hole; Adjusting screw A is threadedly engaged with both the cross bar and the longitudinal bar, and adjusting screw A is a magnetic screw;

[0012] By rotating the corresponding adjusting screw A to make the adjusting screw A magnetically contact the first frame unit, each first frame unit can be located in the same plane to form a plane adjustment structure.

[0013] As a preferred technical solution of the present application, the cross bar and the first frame unit are fixed at the transverse through-hole by a locking screw, and the longitudinal bar and the first frame unit are also fixed at the longitudinal through-hole by a corresponding locking screw.

[0014] As a preferred technical solution of the present application, the cross bar and the longitudinal bar are channel steel bars with a U-shaped cross-section. A long waist-shaped hole is opened along the length direction at the bottom surface of the U-shaped channel steel bar; The locking screw passes through the threaded hole of the first frame unit and then passes through the long waist-shaped hole on the cross bar or the longitudinal bar and is locked.

[0015] As a preferred technical solution of the present application, the first frame unit includes a rectangular frame and auxiliary strips, and the auxiliary strips are arranged in a staggered manner within the rectangular frame; Transverse through-holes and longitudinal through-holes are opened at different thickness positions at the edges of the rectangular frame; When the adjusting screw A is rotated, the adjusting screw A magnetically contacts the auxiliary strip.

[0016] As a preferred technical solution of the present application, in the first frame unit, the front surface of the auxiliary strip is flush with the front surface of the rectangular frame; The cross bar and the longitudinal bar are both arranged at the back of the auxiliary strip;

[0017] The locking screw passes through the threaded hole at the edge of the rectangular frame from the back and is locked with the corresponding cross bar or longitudinal bar; Or, the locking screw passes through the threaded hole at the edge of the rectangular frame from the front and is locked with the corresponding cross bar or longitudinal bar.

[0018] As a preferred technical solution of the present application, it further includes a second frame unit, and the second frame unit is arc-shaped; the outer frame edges between the side wall frame I, the top wall frame II, and the bottom wall frame III are connected by bolts through the second frame unit.

[0019] As a preferred technical solution of the present application, it further includes a third frame unit, and the third frame unit is in the shape of an eighth spherical frame; between the side wall frame I, the top wall frame II, and the bottom wall frame III, at the space angle, they are connected by bolts through the third frame unit.

[0020] As a preferred technical solution of the present application, LED display screen blocks are provided on the front surfaces of the side wall frame I, the top wall frame II, the bottom wall frame III, the second frame unit, and the third frame unit; an adjustable adjusting screw B is provided on the back surface of the LED display screen block, and the adjusting screw B is a magnetic screw; after rotating the adjusting screw B to an appropriate length, the LED display screen block is placed in an adsorbed manner.

[0021] For the convenience of understanding, the core principle of this solution is described as follows: a. The side wall frame I, the top wall frame II, and the bottom wall frame III are all formed by splicing multiple first frame units in an array arrangement, and longitudinal through holes and transverse through holes are provided in the first frame units; when multiple first frame units are arranged in an array, a cross bar is passed through each first frame unit in the same row, and a longitudinal bar is passed through each first frame unit in the same column, thus forming the overall side wall frame I / top wall frame II / bottom wall frame III; b. By rotating the adjusting screw A, the lengths of the adjusting screw A extending out and abutting on the first frame unit are different, so that the fronts of the first frame units arranged in an array can be well located on the same plane to a certain extent (when the LED display screen block is adsorbed and placed on the side wall frame I / top wall frame II / bottom wall frame III, it can initially ensure the flatness of multiple LED display screen blocks on a certain wall frame. Combining with the adjustment of the adjusting screw B on the back surface of the LED display screen block, it can further ensure the flatness of multiple LED display screen blocks on a certain wall frame, thereby improving the visual effect); c. After the adjustment is completed, the cross bar and the longitudinal bar are locked and fixed to the corresponding first frame units with locking screws, so that the side wall frame I, the top wall frame II, and the bottom wall frame III form an overall with relatively high flatness.

[0022] The present utility model has the following advantages:

[0023] The flatness of the fronts of the side wall frame I, the top wall frame II, and the bottom wall frame III can be adjusted by the adjusting screw A, thereby improving the flatness of the fronts of the side wall frame I, the top wall frame II, and the bottom wall frame III; when subsequently adsorbing and placing the LED display screen blocks, the flatness of the LED display screen blocks during placement is further adjusted in combination with the adjusting screw B; in this way, when multiple LED display screen blocks form an overall display screen on the fronts of the side wall frame I, the top wall frame II, and the bottom wall frame III, the overall display screen has good flatness, thereby improving the visual perception of people;

[0024] In addition, the side wall frame I, the top wall frame II, and the bottom wall frame III can be quickly connected through the second frame unit and the third frame unit, so as to form a cuboid space with a radian at the corner and also a radian at the top corner. Description of the Drawings

[0034] The following further describes the present utility model in conjunction with the drawings, but the protection scope of the present utility model is not limited to the following description.

[0035] It should be noted that the orientation or positional relationship indicated by "left", "right", etc. is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship when the product of this utility model is normally placed, or the orientation or positional relationship commonly understood by those skilled in the art. Such terms are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0036] Those skilled in the art can understand that, unless otherwise defined, all terms (including technical terms and scientific terms) used herein have the same meaning as the general understanding of those of ordinary skill in the art to which this application belongs. It should also be understood that terms such as those defined in a general dictionary should be understood to have a meaning consistent with the meaning in the context of the prior art, and will not be interpreted with an idealized or overly formal meaning unless specifically defined as here.

[0037] It should be noted that, without conflict, the embodiments and the features and technical solutions in the embodiments in the present utility model can be combined with each other.

[0038] As Figures 1-5 shown, the back frame structure for a spatial display screen includes four side wall frames Ⅰ, one top wall frame Ⅱ, and one bottom wall frame Ⅲ, which together form a cuboid space structure; and the side wall frames Ⅰ, the top wall frame Ⅱ, and the bottom wall frame Ⅲ are all formed by splicing a plurality of first frame units 100 arranged in an array.

[0039] The first frame unit 100 has a transverse through hole 101 and a longitudinal through hole 102. The positions of the transverse through holes 101 of the first frame units 100 in the same row in the corresponding wall frame are opposite, and are penetrated by the same cross bar 400. The positions of the longitudinal through holes 102 of the first frame units 100 in the same column in the corresponding wall are opposite, and are penetrated by the same longitudinal bar 500.

[0040] There is a gap in the thickness direction between the cross bar 400 and the transverse through hole 101, and between the longitudinal bar 500 and the longitudinal through hole 102; adjusting screws A600 are threadedly engaged with both the cross bar 400 and the longitudinal bar 500, and the adjusting screw A600 is a magnetic screw.

[0041] In addition, the cross bar 400 and the first frame unit 100 are fixed by locking screws at the transverse through hole 101, and the longitudinal bar 500 and the first frame unit 100 are also fixed by corresponding locking screws at the longitudinal through hole 102.

[0042] During operation: a. Place multiple first frame units 100 in an array on a flat ground, forming a form of multiple horizontal rows and multiple vertical columns and aligning each first frame unit 100 with each other - similar to a table shape; b. Pass a cross bar 400 through the horizontally through holes 101 at opposite positions in each first frame unit 100 in the same horizontal row. If there are multiple horizontally through holes 101 in the first frame unit 100 of this horizontal row, pass multiple cross bars 400. In this way, pass cross bars through each first frame unit 100 in each horizontal row in turn; c. Referring to the method in b above, pass the vertical bar 500 through the vertically through holes 102 of each first frame unit 100 in the corresponding vertical column; d. Then screw the adjusting screw A600 into the threaded holes of the cross bar 400 and the vertical bar 500, making the adjusting screw A600 abut against the first frame unit 100 to form an outward lifting force. In addition, the adjusting screw A600 is a magnetic valve rod and the corresponding part of the first frame unit 100 is magnetically conductive. Therefore, when the adjusting screw A600 is not in contact with the first frame unit 100, an adsorption force opposite to the lifting force can be generated; thus, through such a positive and negative adjustment method, good flatness can be achieved at the front between all first frame units 100 in the entire side wall frame I / top wall frame II / bottom wall frame III; e. After the adjustment is completed, use locking screws to lock and fix the corresponding cross bar 400 and the first frame unit 100, and the vertical bar 500 and the first frame unit 100 at the positions of the horizontally through hole 101 and the vertically through hole 102.

[0043] In this embodiment, as shown in the figure, the cross bar 400 and the vertical bar 500 are U-shaped channel steel bars, and long waist-shaped holes are opened along the length direction on the bottom surface of the U-shaped channel steel bars; the locking screw passes through the threaded hole of the first frame unit 100 and then into the long waist-shaped hole on the cross bar 400 or the vertical bar 500 and then locks.

[0044] In this embodiment, refer to Figure 4 and Figure 5 , the first frame unit 100 includes a rectangular frame 110 and auxiliary strips 120, and the auxiliary strips 120 are arranged in a staggered manner within the rectangular frame 110; horizontally through holes 101 and vertically through holes 102 are opened at different thickness positions at the edges of the rectangular frame 110; when the adjusting screw A600 is rotated, the adjusting screw A600 is in magnetic contact with the auxiliary strip 120.

[0045] Furthermore, refer to Figure 4, in the first frame unit 100, the front surface of the auxiliary bar 120 is flush with the front surface of the rectangular frame 110; the cross bar 400 and the longitudinal bar 500 are both arranged at the back of the auxiliary bar 120; the locking screw passes through the threaded hole on the edge of the rectangular frame 110 from the back and is locked and fixed to the corresponding cross bar 400 or longitudinal bar 500. Of course, according to needs, the locking screw can also pass through the threaded hole on the edge of the rectangular frame 110 from the front and be locked and fixed to the corresponding cross bar 400 or longitudinal bar 500. This method is convenient for subsequent adjustment after the entire side wall frame I, top wall frame II, and bottom wall frame III are fixed to the corresponding wall, but generally it is not necessary.

[0046] In this embodiment, referring to Figure 1 , it further includes a second frame unit 200, and the second frame unit is arc-shaped; the outer frame edges between the side wall frame I, the top wall frame II, and the bottom wall frame III are connected by bolts through the second frame unit 200.

[0047] In this embodiment, referring to Figure 1 , it further includes a third frame unit 300, and the third frame unit is in the shape of an eighth spherical frame; between the side wall frame I, the top wall frame II, and the bottom wall frame III, at the space angle, they are connected by bolts through the third frame unit 300.

[0048] In this embodiment, LED display screen blocks are arranged on the front surfaces of the side wall frame I, the top wall frame II, the bottom wall frame III, the second frame unit 200, and the third frame unit 300; an adjustable adjusting screw B is arranged on the back of the LED display screen block, and the adjusting screw B is a magnetic screw; after turning the adjusting screw B to an appropriate length, the LED display screen block is placed in an adsorbed manner (it should be noted that the method of adjusting the LED display screen block by the magnetic adjusting screw B is a prior art, and many LED display screens in this field adopt this adsorbed placement method).

[0049] The above embodiments only represent relatively preferred implementation manners, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
