一种铝合金型材的拼接结构
摘要：
本实用新型涉及一种铝合金型材的拼接结构，该拼接结构包括设置在一个铝合金型材上的孔，以及设置在与之拼接的另一个铝合金型材上的轴；该轴上设有锯齿，并且该锯齿的外侧有约0.2mm过盈，内侧留有约0.1mm间隙；在该轴的前端设有倒入角。轴的长度比所述孔的深度短约0.5mm，在轴的前端形成空腔。通过本实用新型的拼接结构拼接型材，配合后型材外表美观，配合紧密。
摘要（英）：

The utility model relates to a splicing structure for aluminum alloy sections. The splicing structure comprises a hole arranged on one aluminum alloy section and a shaft arranged on another aluminum alloy section spliced with the aluminum alloy section, the shaft is provided with sawteeth, an interference of 0.2mm is arranged on outer sides of the sawteeth, a gap of 0.1mm is reserved on inner sides of the sawteeth, a chamfer is arranged at the front end of the shaft, the length of the shaft is shorter than the depth of the hole by 0.5mm, and a cavity is formed at the front end of the shaft. By the splicing structure for the aluminum alloy sections, matched sections are attractive in appearance and tight in matching.
