Detailed Description
The present invention will be further described with reference to the following examples, which are intended to illustrate only some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, other embodiments used by those skilled in the art without any creative effort belong to the protection scope of the present invention.
Example 1:
as shown in fig. 1-7, an enhanced anti-drop bolt structure is composed of a bolt 1, a bolt fastening piece 2 and a bolt fixing plate 3.
As shown in fig. 5, the tongue 1 is circular, and a circular riveting hole for riveting is arranged inside the tongue 1;
as shown in fig. 6, the bolt fastening plate 2 is provided with a first support leg and a second support leg, the first support leg and the second support leg are opened outwards before riveting, and the bolt fastening plate 2 is riveted in the riveting hole through the outer side of the first support leg and the outer side of the second support leg; the inner side of the first supporting leg is provided with a first positioning clamping leg 4 and a first occlusion part 7, and the inner side of the second supporting leg is provided with a second positioning clamping leg 5 and a second occlusion part 8;
as shown in fig. 7, a bolt fixing plate 3 is provided with a round hole 12 and a positioning clamping groove 11, the bolt fastening plate 2 is fixedly connected with the bolt fixing plate 3 through a first support leg and a second support leg, the first positioning clamping leg 4 and the second positioning clamping leg 5 are clamped in the round hole 12, and the first engaging portion 7 and the second engaging portion 8 are engaged with the bolt fixing plate 3.
When the bolt fixing plate 3 is fixedly connected to the bolt fastening plate 2, the bolt fastening plate 2 between the first support leg and the second support leg is installed in the positioning clamping groove 11.
In this embodiment, the tongue 1 is provided with a caulking notch 6 which is inwardly contracted in an opening portion of the caulking hole, a first inclined surface 9 for caulking the caulking notch 6 is provided on an outer side of the first leg, and a second inclined surface 10 for caulking the caulking notch 6 is provided on an outer side of the second leg.
In this embodiment, the first engaging portion 7 is a plurality of serrated first ribs. The first ribs are arranged at equal intervals. The second occlusion part 8 is a plurality of zigzag second convex ribs. The second convex ribs are arranged at equal intervals.
