[0022] See also Figures 1 to 2 The present invention provides a fastener structure, including a fastener body 10, a fastener door 20, a fastener ring 30, a return member 40, a sub-nail 70, a female nail 60, a functional member 50, a first fixing member 80 and a second fixing member 90. The buckle ring 30 is provided at one end of the fastener body 10, and the fastener body 10 and the buckle ring 30 are connected into a whole through the first fixing member 80. The buckle body 10, the fastener door 20 and the return member 40 are connected into a whole through the second fixing member 90. The functional member 50 and the buckle ring 30 are connected into a whole through the female nail 60 and the sub-nail 70.
[0023] In this embodiment, the first fixing member 80 is a screw, the second fixing member 90 is a rivet, and the return member 40 is a torsion spring. The return member 40 elastically presses against the buckle body 10 and the buckle door 20 at both ends. When the buckle door 20 is pressed, a gap is formed between the buckle body 10 and the buckle door 20, allowing the buckle body 10 to be fastened to other objects. After the buckle door 20 is released, the return member 40 presses against the buckle door 20 to return to its original position and press against the buckle body 10, preventing the buckle body 10 from falling off the object it is mounted on. The first fixing member 80 passes through the buckle ring 30 and is mounted on the buckle body 10. The buckle ring 30 can rotate around the first fixing member 80. The female nail 60 passes through the functional member 50, and the end of the functional member 50 on which the female nail 60 is mounted extends into the buckle ring 30. The female nail 60 is horizontally retained on the buckle ring 30 at both ends. The sub-nail 70 passes through both the buckle ring 30 and the female nail 60 and is fixed to the female nail 60.
[0024] Specifically, the buckle ring 30 is arranged in a "door" shape as a whole. The buckle ring 30 includes a connecting head 31 and two connecting arms 32 connected to the connecting head 31. The connecting head 31 is provided with a through hole 311. The through hole 311 passes through the connecting head 31 in the vertical direction. The end of the connecting arm 32 away from the connecting head 31 is provided with a through hole 321, and the through holes 321 of the two connecting arms 32 are arranged opposite to each other in the horizontal direction.
[0025] The functional component 50 is provided with a fixing head 51, which is provided with a fixing hole 511. The fixing hole 511 extends horizontally through the fixing head 51, and the horizontal length of the fixing head 51 is slightly less than the distance between the two connecting arms 32. The female nail 60 is generally configured as a hollow cylindrical structure, with an axial hole 61 extending along its axial direction. The outer peripheral surface of the female nail 60 near the middle is concave, forming an undercut 62 that extends into the axial hole 61. The length of the female nail 60 is slightly less than the distance between the two connecting arms 32, and the outer diameter of the two ends of the female nail 60 is larger than the diameter of the through hole 321. The sub-nail 70 is generally configured as a rod-shaped structure, with a slot 71 provided on the central outer peripheral surface of the sub-nail 70. The outer diameter of the area outside the slot 71 on the sub-nail 70 is slightly larger than the inner diameter of the undercut 62.
[0026] During assembly, the first fixing part 80 passes through the through hole 311 on the buckle ring 30 and is installed at the bottom of the buckle body 10, the female nail 60 passes through the fixing hole 511 of the fixing head 51 on the functional part 50, and then the fixing head 51 on the functional part 50 and the female buckle are placed between the two connecting arms 32, and the center of the axial hole 61 on the female nail 60 is aligned with the center of the through hole 321 of the connecting arm 32. Then, the sub-nail 70 is inserted into the through hole 321 of the connecting arm 32 and the axial hole 61 of the female nail 60 from one side, and then pressure is applied to the sub-nail 70 with a hand beer machine to make the sub-nail 70 further pass through the female nail 60. The two ends of the sub-nail 70 are inserted into the through holes 321 of the two connecting arms 32, and the female nail 60 is clamped between the two connecting arms 32 in the horizontal direction. The hook of the female nail 60 is clamped in the clamping groove 71 of the sub-nail 70 to prevent the sub-nail 70 from falling off from the female nail 60, and the functional part 50 can rotate around the center of the through hole 321.
[0027] The beneficial effect of the fastener structure of the present invention is that: by arranging a sub-nail 70 and a female nail 60, and arranging two connecting arms 32 on the buckle ring 30, a card slot 71 is provided on the sub-nail 70, and a barb is provided on the female nail 60. During assembly, the female nail 60 passes through the fixed head 51 of the functional part 50, and the fixed head 51 equipped with the female nail 60 extends between the two connecting arms 32 of the buckle ring 30, and the sub-nail 70 passes through the connecting arm 32 and the female nail 60 of the buckle ring 30 at the same time, and the barb of the female nail 60 is clamped in the card slot 71 of the sub-nail 70, thereby connecting the functional part 50 and the buckle ring 30 into a whole. During installation, there is no need to use screw fixing or riveting, which effectively improves assembly efficiency, reduces defective rate, improves product appearance quality, and has strong practicality.
