A convex portion 4021 is provided at the second foam glue 402 corresponding to the groove 4011. The shapes of the groove 4011 and the convex portion 4021 match each other, and the convex portion 4021 is embedded in the groove 4011; a profiling plate 6, the profiling plate 6 is arranged on an end face of the side plate 102 opposite to the bottom plate 101, the profiling plate 6 is located at the connection between the first foam glue 401 and the second foam glue 402, and the profiling plate 6 is arranged at the inner edge and the outer edge of the upper end of the side plate 102, the groove 4011 and the convex portion 4021 are located between the inner profiling plate 6 and the outer profiling plate 6, and the waterproof foam glue 4 is close to the profiling plate 6; a cover plate 7, the cover plate 7 is pasted on an end face of the side plate 102 opposite to the bottom plate 101 through the waterproof foam glue 4.

[0028] The technical solution of the utility model is to set a first foam glue 401 and a second foam glue 402, the first foam glue 401 and the second foam glue 402 are set as a convex and a concave, the convex part 4021 is set on the second foam glue 402, and the concave part 4011 is set on the first foam glue 401. The existence of the convex part 4021 makes the end of the second foam glue 402 step-shaped. In this way, the splicing gap between the first foam glue 401 and the second foam glue 402 is also step-shaped. The convex part 4021 is inserted into the groove 4011 to prevent liquid from entering the interior of the middle frame 1. By setting the profiling plate 6, one side When the first foam glue 401 and the second foam glue 402 are spliced, a gap for accommodating the first foam glue 401 and the second foam glue 402 is formed between the inner profiling plate 6 and the outer profiling plate 6, and the ends of the first foam glue 401 and the second foam glue 402 are arranged in the gap.
