    • To enhance the positioning accuracy between primary members and auxiliary members without need of latch parts such as rivets, an insertion frame structure includes: a pair of primary members (10) having L-shaped cross-sections and placed with the L shapes facing to each other symmetrically; and several auxiliary members (20) having angular U-shaped cross-sections between the primary members (10). The primary members (10) and the auxiliary members (20) are joined at latch portions. The latch portions of the primary members (10) have clearance-shaped latch holes (11a, 11b). The latch portions of the auxiliary members (20) have convex portions to be inserted into the latch holes (11a, 11b), Each latch hole (11a, 11b) has a clearance with a larger dimension than a plate thickness (t) of the auxiliary members (20), and continuously from the clearance, a clearance with a dimension smaller than the plate thickness (t) of the auxiliary members (20).
    • 为了提高主要部件和辅助部件之间的定位精度,而不需要诸如铆钉的闩锁部件,插入框架结构包括:一对具有L形横截面的主要部件(10),并且L形面向每个 其他对称 以及在主要构件(10)之间具有有角度的U形横截面的多个辅助构件(20)。 主构件(10)和辅助构件(20)在闩锁部分处连接。 主构件(10)的闩锁部分具有间隙形状的锁定孔(11a,11b)。 辅助构件(20)的闩锁部分具有插入到所述闩锁孔(11a,11b)中的凸起部分,每个闩锁孔(11a,11b)具有比所述插入孔(11a,11b)的板厚度 辅助构件(20),并且从间隙连续地开始具有小于辅助构件(20)的板厚度(t)的尺寸的间隙。
