Detailed Description
The present invention is further described below in conjunction with embodiments, which are merely some, but not all embodiments of the present invention. Based on the embodiments of the present invention, other embodiments that may be used by those of ordinary skill in the art without making any inventive effort are within the scope of the present invention.
Example 1:
as shown in fig. 1-7, an enhanced anti-falling lock tongue structure is composed of a lock tongue head 1, a lock tongue fastening piece 2 and a lock tongue fixing plate 3.
As shown in fig. 5, the lock tongue 1 is circular, and is internally provided with a circular riveting hole for riveting;
as shown in fig. 6, the bolt fastening piece 2 is provided with a first support leg and a second support leg, the first support leg and the second support leg are outwards opened before riveting, and the bolt fastening piece 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 support leg is provided with a first positioning clamping foot 4 and a first occluding part 7, and the inner side of the second support leg is provided with a second positioning clamping foot 5 and a second occluding part 8;
as shown in fig. 7, the lock tongue fixing plate 3, a round hole 12 and a positioning slot 11 are formed in the lock tongue fixing plate 3, the lock tongue fastening piece 2 is fixedly connected with the lock tongue fixing plate 3 through a first support leg and a second support leg, the first positioning pin 4 and the second positioning pin 5 are clamped in the round hole 12, and the first clamping portion 7 and the second clamping portion 8 are clamped on the lock tongue fixing plate 3.
When the lock tongue fixing plate 3 is fixedly connected to the lock tongue fastening piece 2, the lock tongue fastening piece 2 between the first support leg and the second support leg is installed in the positioning clamping groove 11.
In this embodiment, the latch bolt head 1 is provided with a caulking bayonet 6 that is inwardly contracted at an opening portion of the caulking hole, a first inclined surface 9 for caulking with the caulking bayonet 6 is provided at an outer side of the first leg, and a second inclined surface 10 for caulking with the caulking bayonet 6 is provided at an outer side of the second leg.
In this embodiment, the first engaging portion 7 is a plurality of sawtooth-shaped first ribs. The first ribs are arranged at equal intervals. The second engaging portion 8 is a plurality of sawtooth-shaped second ribs. The second ribs are arranged at equal intervals. The first convex rib and the second convex rib are meshed into the material of the bolt fixing plate 3 during riveting, so that the bolt fixing plate 3 is tightly combined with the bolt fixing plate.
In this embodiment, two sides of the tongue fixing plate 3 are provided with a protrusion 13 for abutting against the tongue 1.
As shown in fig. 1-4, the specific composition is as follows: the bolt fastening piece 2 is installed on the positioning groove of the upper front end of the bolt fixed plate 3, the outside of the first stabilizer blade and the second stabilizer blade of the bolt fastening piece 2 is in interference fit with the riveting hole of the bolt 1, after the bolt 1 is riveted, the bolt fastening piece 2 is folded inwards, at this moment, two positioning clamping feet on the bolt fastening piece 2, namely a first positioning clamping foot 4 and a second positioning clamping foot 5, are clamped into a round hole 12 at the front end of the bolt fixed plate 3, and simultaneously, a first meshing part 7 and a second meshing part 8 of the two groups of saw-tooth shapes on the inner side surfaces of the first stabilizer blade and the second stabilizer blade of the bolt fastening piece 2 are meshed into the material of the bolt fixed plate 3, so that the bolt fastening piece 3 is tightly combined together, and the structure design is the initiative of the industry.
