Adopt the utility model provides a when 2 riveting lock tongues 1 and spring bolt fixed plate 3 of spring bolt fastening plate, specifically as follows:
the method comprises the following steps: lock tongue 1, spring bolt fastening piece 2, spring bolt fixed 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 leg 15 and a second leg 16, the first leg 15 and the second leg are outwardly opened before riveting and are V-shaped, and the bolt fastening plate is riveted in the riveting hole through the outer side of the first leg 15 and the outer side of the second leg.
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 15 and a second support leg 16, 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 15 and the second support leg 16 is installed in the positioning clamping groove 11.
In the present 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 15, and a second inclined surface 10 for caulking the caulking notch 6 is provided on an outer side of the second leg 16.
In this embodiment, the first engaging portion 7 is a plurality of serrated first ribs. The first ribs are arranged at equal intervals.
