[0025] like Figure 1-3 As shown, a frame structure that is easy to disassemble includes an upper iron frame 110 and a backlight frame.

[0026] The upper iron frame 110 has a first top surface 111 and a first outer side wall 112, the first outer side wall 112 is vertically connected to the periphery of the first top surface 111, and a display window 113 is opened in the middle of the first top surface 111 for exposing the display area of ​​the liquid crystal panel 200;

[0027] The backlight frame includes a lower iron frame 130 and a middle iron frame or middle rubber frame 120, wherein the lower iron frame 130 has a bottom surface 131 and an inner side wall 132, wherein the inner side wall 132 is vertically connected to the periphery of the bottom surface 131; the middle iron frame or middle rubber frame 120 has a second top surface 121 and a second outer side wall 122, wherein the second outer side wall 122 is vertically connected to the second top surface 121, and a light exit window 123 is provided in the middle of the second top surface 121 for emitting backlight from the backlight module 300;

[0028] When the upper iron frame 110 is assembled with the backlight frame, a first space for assembling the liquid crystal panel 200 is formed between the first top surface 111 and the second top surface 121 , and a second space for assembling the backlight module 300 is formed between the second top surface 121 and the bottom surface 131 .

[0029] The first outer wall 112 is located outside the second outer wall 122; the first outer wall 112 is provided with a plurality of clip holes 114, and a plurality of clips 123 are protruded from a surface of the second outer wall 122 on one side facing the first outer wall 112, and one clip 123 is correspondingly embedded in one of the clip holes 114; a plurality of grooves 124 are provided on a surface of the second outer wall 122 on one side facing the first outer wall 112, and the plurality of grooves 124 extend downward to the lower end of the second outer wall 122 and are connected to the outside.

[0030] The frame structure of the present invention adopts matching card holes 114 and buckles 123 to connect and assemble between the first outer wall 112 of the upper iron frame 110 and the second outer wall 122 of the backlight frame. After the assembly is completed, the gap between the first outer wall 112 and the second outer wall 122 is very small; and the groove 124 is provided on the second outer wall 122. When it is necessary to disassemble and separate the upper iron frame 110 from the backlight frame, a knife or a card can be inserted from the lower end into the groove 124 between the first outer wall 112 and the second outer wall 122, and the first outer wall 112 can be pried outwards to disengage the card holes 114 on the first outer wall 112 and the buckles 123 on the second outer wall 122, and finally the upper iron frame 110 can be disassembled from the backlight frame, which greatly facilitates the disassembly and separation of the upper iron frame 110 from the backlight frame.

[0031] In this embodiment, the gap between the first outer wall 112 and the second outer wall 122 is less than 1 mm to improve the assembly stability between the upper iron frame 110 and the backlight frame, and prevent the upper iron frame 110 and the backlight frame from colliding during use of the liquid crystal module.

[0032] Since the gap between the first outer wall 112 and the second outer wall 122 is very small, it is difficult to insert a knife or a card for prying open the first outer wall 112 into the gap between the first outer wall 112 and the second outer wall 122. Therefore, the utility model provides the groove 124 on the second outer wall 122 for the knife or the card to be inserted and then pry open the first outer wall 112.

[0033] In this embodiment, the groove 124 has a depth between 0.15 mm and 0.25 mm.

[0034] If the frame structure is applied to a large-sized liquid crystal module, the frame structure adopts a middle iron frame and the upper iron frame 110 for assembly, and the second top surface 121 and the second outer side wall 122 are arranged on the middle iron frame; if the frame structure is applied to a small or medium-sized liquid crystal module, the frame structure adopts a middle rubber frame 120 and the upper iron frame 110 for assembly, and the second top surface 121 and the second outer side wall 122 are arranged on the middle rubber frame 120.

[0035] The upper end of the buckle 123 is an inclined surface, and the inclined surface makes the thickness of the buckle 123 gradually decrease from top to bottom. When the upper iron frame 110 is buckled from above to the outside of the backlight frame, the inclined surface of the buckle 123 first abuts against the lower end of the first outer wall 112, and in the process of the upper iron frame 110 moving downward, the first outer wall 112 is pushed outward to expand the lower opening area of ​​the upper iron frame 110, so as to facilitate the buckle 123 to enter the upper iron frame 110 and finally embed into the corresponding buckle hole 114.

[0036] The plurality of grooves 124 are roughly divided into three parts according to their positions on the second outer side wall 122, wherein a portion of the grooves 124 corresponds to the buckles 123 and is located next to the corresponding buckles 123, a portion of the grooves 124 is located at both ends of the second outer side wall 122 to be close to the four corners of the upper iron frame 110, and a portion of the grooves 124 is located in the middle of the second outer side wall 122.

[0037] In this embodiment, the distance between the corresponding groove 124 and the buckle 123 is greater than 2.0 mm.

[0038] The inner side wall 132 of the lower iron frame 130 of the frame structure and the second outer side wall 122 of the middle iron frame or middle rubber frame 120 can also be connected and assembled by using matching holes and buckles, and the second outer side wall 122 is located outside the inner side wall 132; a plurality of receiving grooves 132 are provided on the surface of the inner side wall 132 facing the second outer side wall 122, and one of the grooves 124 corresponds to one of the receiving grooves 132 and is located in the corresponding receiving groove 132.
