Definitions

  • This invention relates to a quick fastener, particularly to a fastener suitable for joining necklace quickly.
  • the present invention provides a fastener which is characterized in that the fastener consists of a locknut, a pin and a spring; the shape of said locknut appears as a barrel with bore surface being a flight of one-step, on the portion of smaller bore diameter there are at least one slot extending outwards in the radial direction and axially passing through the whole portion of smaller bore diameter, said slot has such a depth that the radius of the bottom portion of the slot must be less than or equal to the radius of the larger bore, and at least one positioning groove extending axially and occupying only a part length of the portion of smaller bore diameter, said positioning groove has the width approximate to that of the slots, while the number of said positioning grooves is equal to that of the slots; said pin is a cylinder at whose end there is at least one convex segment extending outwards in the radial direction, the number, the position relative to each other, the width and the height of the convex segments just match the number, the position relative
  • the said spring can be mounted on the spring base of the locknut, and is propped with its free end against the butt end of the pin; the said spring can also be mounted on the spring base of the pin, and is propped with its free end against the butt end of the locknut.
  • the fastener in accordance with the present invention can be either joined or separated conveniently, its joining strength is high, its manufacturing technology is simple and its cost is low.
  • the fastener can be made from metal or polymeric material by one of the following processing methods, such as injection molding, die casting, machining and impact forming.
  • the first embodiment of the fastener in accordance with the invention is shown from Fig. 1 to Fig. 11, where Fig. 1 shows an assembly view of the fastener and indicates the fastener in a joined state.
  • the fastener includes a locknut set 18, a pin set 1 and a spring 5.
  • Said locknut set 18 consists of a locknut 6 (Figs. 10 and 11) and an auxiliary part 4' (Figs. 6 and 7) secured to the end of the locknut 6.
  • the shape of said locknut 6 appears as a barrel with its bore surface being a flight of one step. On the bore surface of the portion of smaller bore diameter there are at least two slots 63 oppositely positioned in the radial direction.
  • the depths of these two said slots 63 are radially extending outwards and their longitudinal lengths axially pass through the portion of smaller bore diameter.
  • the longitudinal lengths of these positioning grooves 61 occupy only a part length of the portion of smaller bore diameter and their widths are preferably equal to those of the slots 63.
  • the auxiliary part 4' is welded on the end with larger bore diameter of the locknut 6.
  • the said pin set 1 includes a pin 2 (Figs. 2 and 3), a pin sleeve 3 (Fig. 4 and 5) and an auxiliary part 4 (Figs. 8 and 9).
  • the shape of said pin 2 is just a cylinder with a flight of two steps, in which the maximum diameter, i.e. the outer diameter of the auxiliary base 24 matches the inner diameter of the pin sleeve 3, the medium diameter, i.e. the outer diameter of the spring base 23 matches the inner diameter of the spring 5, and the minimum diameter of the portion 22 matches the inner diameter of the smaller bore 62 on the locknut 6.
  • the maximum diameter i.e. the outer diameter of the auxiliary base 24 matches the inner diameter of the pin sleeve 3
  • the medium diameter, i.e. the outer diameter of the spring base 23 matches the inner diameter of the spring 5
  • the minimum diameter of the portion 22 matches the inner diameter of the smaller bore 62 on the locknut 6.
  • At the end of the portion 22 of minimum diameter there are two convex segments 21 oppositely positioned in the radial direction and radially extended outwards. Both the widths and the heights of these convex segments 21 match the corresponding ones of the positioning grooves 61 of the locknut
  • the pin 2 Inside the pin sleeve 3 is located the pin 2, whose auxiliary base 24 is welded onto the end of the pin sleeve 3.
  • the spring 5 is mounted on the spring base 23 of the pin 2, pressing onto the butt end 66 of the locknut 6 with its free end.
  • the auxiliary part 4 is welded onto the butt end of the auxiliary base 24.
  • All parts of the present embodiment can be produced without any difficulties from metal or polymeric material by one of the following processing methods, such as injection molding, die casting, machining and impact forming.
  • the second embodiment of the fastener in accordance with the invention is illustrated in the Figs. from 12 to 19.
  • the locknut and the pin in the present embodiment are the same as in the first embodiment, the main differences lie in that the spring 5 is located inside the portion of larger bore diameter of the locknut 8, and is pressed onto the butt end of the pin 7 with its free end, meanwhile, the pin 7 possesses an integral structure having a rod-shaped auxiliary part 72 with a flange71 (Figs. 14 and 15), and the auxiliary part 9 also possesses a spring base 91 with an auxiliary base 94, a rod-shaped part 92 and a flange 93 (Figs. 18 and 19).
  • the auxiliary base 94 of the auxiliary part 9 is welded to the locknut 8 at the end of the portion of larger bore diameter.
  • This embodiment can be used, such as for shoelaces, in this case, the only thing needed is to join the shoelaces 11 to auxiliary parts by coverings 10.
  • Fig. 20 The third embodiment of the fastener in accordance with the invention is illustrated in Fig. 20.
  • This embodiment is basically the same as the first embodiment, the only difference lies in that the pin 12 is an integral structure having a pin sleeve and a auxiliary part, moreover, the auxiliary part 14 is a ring hooked to the lock nut 13.
  • FIGs. 21 and 22 The fourth embodiment of the fastener in accordance with the invention is illustrated in Figs. 21 and 22.
  • This embodiment is basically the same as the second embodiment, the only difference lies in that the locknut 19 possessing the slots and the positioning grooves is at first fabricated independently, and then fixed to the core of the barrel 20 with larger bore diameter by using the screws 17.
  • the fifth embodiment of the fastener in accordance with the invention is illustrated in Fig. 23, its difference lies in that said fastener can be used to join two parts 102, 102' propped against each other. Said joined parts 102,102' possess the through hole 103.
  • One end of the pin 2 is shaped like a head of an usual bolt (Figs. 28 and 29); the locknut 6 (Figs. 26 and 27) has only one smaller bore diameter; there are two concave notches 104 positioned oppositely in the radial direction of the inner hole of the ring gasket 101, these concave notches allow the convex segments of the pin 2 to be passed through.
  • the ring gasket 101 can be omitted; or alternatively, if in the inner surface of the through hole 103 the axial slots are shaped to position oppositely in the radial direction, and to extend axially through the through hole 103 and outwards radially, the ring gasket can also be omitted.
