Drawings
FIG. 1 is an assembly schematic diagram of a bolt embedding structure of an overhead component of the present utility model;
fig. 2 is a schematic structural view of a bolt embedding structure of an overhead component of the present utility model.
Detailed Description
The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.
As shown in fig. 1 and 2, the passenger car of the utility model comprises a top-mounted part bolt pre-burying 1 and a whole car top framework 2.
The top-mounted part bolt pre-buried structure 1 is arranged at the top of the whole vehicle and comprises a connecting embedded part 11, a bolt 12 and a groove-shaped part 13.
The connecting embedded part 11 is of a plate-shaped structure, a through hole is arranged in the center of the connecting embedded part, and two ends of the connecting embedded part are respectively welded with the whole vehicle top framework 2.
The bolt 12 is movably assembled with the connecting embedded part 11, the rod part penetrates through the central through hole of the connecting embedded part 11 and is in clearance fit with the central through hole, and the head part is movably clamped on one side of the connecting embedded part 11;
the bolts 12 are profiled bolts, preferably square bolts.
The groove-shaped piece 13 is arranged outside the central through hole of the connecting embedded piece 11, covers the head of the bolt 12, is welded and fixed with the connecting embedded piece 11, and limits the bolt 12; the groove of the groove-shaped piece 13 is matched with the head of the bolt 12, the width of the groove is larger than that of the head of the bolt 12, and the depth of the groove is larger than the thickness of the head of the bolt 12;
the channel 13 may be any structure having a receiving space that mates with the head of the bolt 12; in this embodiment, a channel steel structure is adopted, the groove walls at two sides of the channel steel structure are welded at two sides of the central through hole of the connecting embedded part 11, the head of the bolt 12 is accommodated and limited, the bolt 2 is fixed, and the bolt 12 and the connecting embedded part 11 are connected into a whole.
