When the abutting member 32 of each coupling unit 3 When pressed against the first surface 211, the first positioning member 23 and the second positioning member 33 will be locked to each other, so that each coupling unit 3 can be firmly coupled to the board 21 without falling off. It should be particularly noted that the end of the second positioning member 33 away from the abutting member 32 will gradually shrink to form a taper, so that the coupling unit 3 can smoothly pass through the corresponding through hole 22. And the position of the second positioning member 33 close to the abutting member 32 produces a tight-fitting interference effect. Of course, each coupling unit 3 can also be provided with a protruding strip 34 at an appropriate position on the outer surface of the through member 31, so that when each coupling unit 3 is coupled to the board 21, the board 21 is clamped Between the protruding bar 34 and the abutting member 32, it is ensured that each coupling unit 3 will not be easily separated from the board 21 and fall off.

Thereby, a form with a small neck width and a large head width is formed, so that the connecting post 421 of each connecting member 42 is less likely to be detached from the locking space 310 of the corresponding connecting unit 3 to enhance the degree of coupling.

Refer to FIG. 6, which is a third preferred embodiment of the frame device of the display of the present invention, which is roughly the same as the first preferred embodiment, except that, in this embodiment, the perforating member of each combining unit 3 The limiting block 312 of 31 is arranged along the surrounding wall 311 to form an annular convex strip shape, and each joining member 42 has a connecting post 421 extending from the housing 41 and a surrounding connecting post 421 arranged Convex ribs 424.

The operation method is the same as that of the first preferred embodiment. First, the coupling units 3 are respectively coupled to the plate body 21 through the corresponding through holes 22, and then, when each coupling unit 3 is butted with each coupling member 42 As shown in FIG. 7, the limiting block 312 interferes with the connecting post 421, and the rib 424 interferes with the surrounding wall 311 to form a double loop interference effect, which can further strengthen the original single loop The interference effect of contact can also enhance the degree of bonding. It should be particularly noted that the inclined surface portion marked in FIG. 7 represents an area that will be squeezed and deformed during the bonding process.

In addition, as shown in FIG. 7, in this embodiment, the clamping space 310 of each coupling unit 3 is in the shape of a blind hole. Of course, in actual implementation, the clamping space 310 of each coupling unit 3 can also be made The space 310 is in a penetrating shape as shown in FIG. 3 or FIG. 5.
