Description

  The present invention relates to a structure of a metal fastener tooth for a wire fastener, and refers to a combination structure of a metal tooth and a fastener tape, and the metal tooth has a double meshing fixing effect and has improved anti-missing and tooth slip prevention strength. . Further, in the engaging operation in which the left and right metal engaging teeth are engaged or separated by the concave arc surface of the engaging tooth head, the frictional and pressing resistance is reduced, and the sliding is made smooth.

  A fastener tape 3 (see FIG. 1) on both the left and right sides of a known metal wire fastener is a metal tooth press machine (not shown) or a dental implanting machine (not shown). It fixes to the centerline part 31. The main body 40 of the metal tooth 4 includes a tank hole 41 that penetrates, and a narrowed part 412 (see FIG. 3) and a wide part 413 are installed in order from the open end 411 of the tank hole 41 (see FIG. 2) to the inside. Then, a meshing portion 414 is formed in the vicinity of the open end 411 of the tank hole 41, and the meshing portion 414 and the centerline portion 31 of the fastener tape 3 are meshed and fixed. The disadvantages of the above structure are as follows.

  The metal tooth 4 is fixed to the centerline portion 31 of the fastener tape 3 by a meshing portion 414 (see FIG. 2) close to the opening end 411. However, since the meshing area is small, the metal tooth 4 is displaced after use. The slider 5 is easy to fall off and may not be usable when the slider 5 is slid up and down.

  In the process of meshing the metal service teeth 4 opposite to the left and right sides of the fastener tape 3 (see FIG. 1), one side end 421 above the service tooth head 42 of the metal service tooth 4 on one side is different. Since the frictional force between the metal teeth 4 ′ and the lower side corner 401 ′ of the main body 40 ′ is generated by friction with each other, the operation of meshing and separating is likely to be unsmooth, thereby opening and closing the metal wire fastener. Is not smooth and can no longer be used.

The metal service teeth 1 are arranged at intervals in the left-right direction and fixed to the center line portions 211 on both the left and right sides of the metal wire fastener 2 (see FIG. 7). Among them, the metal service tooth 1 includes a main body 10, and has a tank hole 11 (see FIG. 6) penetrating in the middle of one side of the main body 10.

  A lower side of the main body 10 is provided with a tooth head 12 protruding upward, and the outer end of the tank hole 11 on the one side of the main body 10 forms an open end 111. Further, the tank hole 11 is provided with a first narrowed part 112 (see FIG. 6), a first widened part 113, a second narrowed part 114, and a second widened part 115 inward from the opening end 111. The opposing first engaging part 116 and the opposing second engaging part 117 are formed. Further, the center line 211 of the fastener tape 21 is engaged and fixed at the first engagement part 116 and the second engagement part 117, and the center part 211 is forcibly deformed to widen the engagement area and increase the teeth. It has the advantage of improving the strength to prevent slipping out and tooth slipping.

  In other words, the metal engagement tooth 1 is stabilized and the durability is increased by improving the engagement strength between the teeth and the core (that is, the center line portion 211) by the second engagement portion 117. The double engagement fixing effect prevents the metal tooth 1 from being displaced or dropped, and the service life is extended relatively. In addition, a concave tank 13 is provided at the bottom of another side of the main body 10 of the metal tooth 1 described above, and the upper surface of the other side of the main body 10 is inclined to the one side of the tooth head 12 protruding upward.
