Detailed Description

In order to explain technical contents, structural features, and effects achieved by the present invention in detail, the following description is given in conjunction with the embodiments and the accompanying drawings.

As shown in fig. 1, fig. 2 and fig. 3, the automatic assembling weldless stamping type lobster clasp 100 of the present invention includes a clasp 1, an intermediate member 2 and a torsion spring 3, wherein the intermediate member 2 has a pivot portion 21, an operating portion 22 and a fastening portion 23, the pivot portion 21 has a pivot central axis 211, the intermediate member 2 is pivoted to the clasp 1 through the pivot central axis 211, the fastening portion 23 and the clasp 1 form a closed connecting ring, and the operating portion 22 extends out of the clasp 1 for a user to open or close the connecting ring; the torsion spring 3 is sleeved on the pivot central shaft 211, the pivot portion 21 is provided with a sinking groove 212 surrounding the pivot central shaft 211, and the torsion spring 3 is located in the sinking groove 212. Therefore, the main body of the torsion spring 3 can be further limited, and the torsion spring 3 is prevented from generating large displacement. A pressing part 221 extends outwards from the middle of the upper edge of one side of the operating part 22, one end of the torsion spring 3 presses against the pressing part 221, the end of the torsion spring 3 is of a bent structure 32 so as to be pressed against the buckle body 1 conveniently during assembly, the other end of the torsion spring 3 is bent to form a hook body 31, and the hook body 31 is buckled on one side of the middle part 2, so that the torsion spring 3 is positioned on the middle part 2. The fastener 1 and the intermediate member 2 are both formed into an integral structure by stamping. The fastener 1 and the intermediate piece 2 are integrally formed in a stamping mode, so that welding processing is not needed, and automatic assembly is realized.

Referring to fig. 1, 2 and 3, the buckle body 1 has a hook 11, two mounting portions 12 and two connecting portions 13 connected in sequence, a mounting gap 121 is formed between the two mounting portions 12, the middle member 2 is disposed in the mounting gap 121, and the pivot central shaft 211 is pivoted to the mounting portions 12. Specifically, the two connecting portions 13 are annular structures, an annular step 131 is arranged on the inner side of any one of the two connecting portions 13, and the annular step 131 and the connecting portion 13 are integrally formed by stamping and drawing; the annular step 131 is tightly sleeved with the inner hole of the annular structure of the other connecting part 13.
