See also Fig. 9, Fig. 9 is the structural representation according to stitching section in the back of the body frame of a kind of panel display apparatus of the utility model the 8th embodiment.As shown in Figure 9, in the present embodiment, an end of the first main splice is provided with two stitching sections, and an end of the structure of stitching section and the corresponding second main stitching section is adaptive, so that an end matching of the first main splice and the corresponding second main splice connects.
Particularly; One end of the first main splice 231 is provided with stitching section 2311,2312; Stitching section 2311,2312 is along being spaced on the length direction of the first main splice 231; Stitching section the 2311, the 2312nd is at the shape of first main splice 231 settings and the adaptive recess of an end of the second main splice 232, to accommodate an end of the second main splice 232.Shown in figure 10, stitching section 2311,2312 is the recess of the relative two sides of an end of not running through the first main splice 231, recess be shaped as rectangle, the second main splice 232 is a vertical bar shaped.
When assembly unit large-size back of the body frame 23, at first select the stitching section 2311 of the end of the contiguous first main splice 231, and select the second main splice 232 of respective widths.End with the second main splice 232 is arranged on the recess of stitching section 2311 subsequently.Subsequently through be spirally connected, mode such as snapping or welding connects an end matching of the second main splice 232 and is fixed on the stitching section 2311.When assembly unit reduced size back of the body frame 23, at first select stitching section 2312, and select the second main splice 232 of respective widths away from the end of the first main splice 231.End with the second main splice 232 is arranged on the recess of stitching section 2312 subsequently.Subsequently through be spirally connected, mode such as snapping or welding connects an end matching of the second main splice 232 and is fixed on the stitching section 2312.On concrete; For example be provided with convexity in the surperficial relevant position of the second main splice 232; Wherein the convexity of the second main splice 232 embeds the recess of first main splice 231 opposite positions, and is to splice the first main splice 231 and the second main splice 232, shown in figure 11.In addition, an end of the said second main splice 232 can be provided with spaced convexity on second main splice 232 length directions of at least two edges, such as two, three or four etc.
Further, the recess of the first main splice 231 is the recess of multi-ladder structure, and second main splice 232 opposite positions are provided with the protuberance with the adaptive multi-ladder structure of recess, and are shown in figure 12.In addition; Shown in figure 13, be example with stitching section 2311, the concave bottom of the first main splice 231 is provided with first through hole 2313; The second main splice 232 is provided with second through hole 2321 corresponding to the position of stitching section 2311; Back of the body frame 23 further comprises fixture 240, and fixture 240 passes first through hole 2313 and second through hole 2321, so that the first main splice 231 and the second main splice 232 are spliced.
Like Figure 14, in another embodiment of the back of the body frame of the utility model panel display apparatus, the recess shapes of the stitching section 2311,2312 of the first main splice 231 is circular.But in other embodiments, those skilled in the art can be arranged to other polygonal shapes such as triangle with the shape of recess fully.
Like Figure 15, in another embodiment of the back of the body frame of the utility model panel display apparatus, stitching section 2311,2312 is for the recess of the relative both sides of running through the first main splice 231, so that an end of the second main splice 232 moves on stitching section 2311,2312.Such as the end at the second main splice 232 pass stitching section 2312 and splicing fixing after, can cut and pass part, and then regulate the length of the second main splice 232 the time as back of the body frame master splice.
In practical application, the two ends of the other end of the first main splice 231 and the 3rd main splice 233 are equipped with two stitching sections, and its structure is identical with the structure of stitching section 2311,2312; And at the two ends of the second main splice 232 and the two ends of the 4th main splice 234, corresponding to condition of different, also correspondingly design or do not design, such as:
1) first kind of situation; Shown in figure 10; Any design can not be carried out at the two ends of the two ends of the second main splice 232 and the 4th main splice 234, and promptly the end is identical with the structure at other positions, when at this time splicing in the different stitching sections 2311 (2312) of selecting first main splice 231 1 ends (other end is handled equally); If the width respective change of wanting to carry on the back frame 23, the length of the then corresponding second main splice 232 and the 4th main splice 234 is also done corresponding selection.That is,, then the second main splice 232 and the 4th main splice 234 are not carried out cutting, or the part that crops is shorter if splice the stitching section 2311 of contiguous first main splice 231 1 ends of choosing; If when selecting to splice away from the stitching section 2312 of first main splice 231 1 ends; Then the second main splice 232 and the 4th main splice 234 are all carried out cutting; According to the distance of stitching section distance first main splice 231 1 ends, the part that crops is also long or shorter;
