The second guiding clamping portion 211 and the second clamping portion 231 are grooves matched with the boss, namely grooves are formed in the first glue edge 21, the second glue edge 22 and the third glue edge 23. The size of the recess of the third glue edge 23 may be substantially the same as the size of the boss on the third side panel 14. By the arrangement, the thickness of the side plate of the iron frame 1 can be reduced, so that the weight of the iron frame 1 is effectively reduced. In the assembly process, the rubber frame 2 can be fixed, the manipulator drives the iron frame 1 to move, and the assembly of the iron frame 1 and the rubber frame 2 is completed.
The locking tongue 241 has a substantially rectangular plate-like structure, one side of the locking tongue 241 facing the third glue edge 23 is fixed to the bottom of the carrying table 25, and the other side of the locking tongue 241 is not connected to the carrying table 25 but is spaced from the carrying table 25.

The length of the clamping tongue 241 (the dimension along the direction from the first glue edge 21 to the second glue edge 22) is smaller than the length of the fourth glue edge 24, and a gap is reserved between the clamping tongue 241 and the first glue edge 21 and the second glue edge 22. And two corners of the clamping tongue 241 far from the third rubber edge 23 are arc-shaped. So arranged, the clamping ear 151 is conveniently inserted between the clamping tongue 241 and the bearing platform 25; the pressure of the liquid crystal panel is basically borne by the bearing table 25 and the clamping lugs 151, the clamping tongues 241 do not bear the pressure of the liquid crystal panel basically, after the liquid crystal panel is installed, the clamping force of the bearing table 25 and the clamping tongues 241 to the clamping lugs 151 can be improved, the fixing firmness of the rubber frame 2 and the iron frame 1 is improved, and a powerful guarantee is provided for the mechanical installation mode of the rubber frame 2 and the iron frame 1; the bottom surface of the clamping tongue 241 can be configured to avoid the bottom of the groove 243, so that the structure is simple, and the processing of the rubber frame 2 is convenient.
To further reduce the possibility of deformation of the latch 241 due to the pressure of the latch 151, a flange 242 (shown in fig. 13) is disposed at the bottom of the carrying platform 25 of the fourth glue edge 24, and the flange 242 is connected to the first glue edge 21 and the second glue edge 22, and the latch 241 is fixed on the flange 242.
The width of the bottom plate 11 of the iron frame 1 near the fourth side plate 15 (the dimension in the direction of the first side plate 12 to the second side plate 13) is larger than the width near the third side plate 14. At this time, as shown in fig. 9, each of the first side plate 12 and the second side plate 13 includes an outer side 122 connected to the fourth side plate 15 and abutting the outer side of the glue edge, and an inner side 123 connected to the third side plate 14 and abutting the inner side of the glue edge, the inner side 123 and the outer side 122 are offset to form an insertion slot for inserting the glue edge, and a first guide engagement portion 121 is provided on the inner side 123. So arranged, when the rubber frame 2 is inserted in place, the first rubber edge 21 and the second rubber edge 22 of the rubber frame 2 are pressed between the outer side edge 122 and the inner side edge 123, so that the first rubber edge 21 and the second rubber edge 22 are prevented from tilting; and the width of the clamping ear 151 may be set to be wider so as to extend to contact with the first glue edge 21 and the second glue edge 22, so that the clamping grooves 212 (shown in fig. 11) may be formed on the first glue edge 21 and the second glue edge 22, so that two ends of the clamping ear 151 are clamped in the clamping grooves 212, thereby further improving the fixing firmness of the clamping ear 151.
Further, as shown in fig. 10, the height of the inner side 123 may be the same as the height of the outer side 122, and the height of the clip 151 may be higher than the height of the outer side 122. The outer surface of the outer side edge 122 is flush with the outer surfaces of the first glue edge 21 and the second glue edge 22, i.e. the outer surfaces of the first glue edge 21 and the second glue edge 22 are provided with receiving grooves 213 for receiving the outer side edge 122. Like this, along gluey frame 2 direction of height, draw-in groove 212 misplaces with holding tank 213, reduces the risk of gluing frame 2 at draw-in groove 212 position deformation, effectively guarantees the fixed fastness of gluing frame 2 and iron frame 1 moreover.
