Description

Buckle installation tool

The present invention relates to a buckle mounting tool, and more particularly to a buckle mounting tool suitable for use in mounting a small diameter buckle to a shaft.

The conventional technique of attaching a buckle to a shaft has always been to use a snap ring plier for a buckle.

(a) and (b) of Fig. 3 show a relationship diagram between a buckle and a shaft in the prior art. The buckle 1 is, for example, a C shape formed of a steel material having elasticity as shown in (a) of Fig. 3 . A wide portion 1A that expands outward in the diameter direction is formed at each end portion of the buckle 1, and a hole 1B is formed in the wide portion 1A. The buckle 1 is formed to be attached to the groove 2A formed at the front end of the shaft 2 shown in (b) of the same figure. In order to be firmly fixed to the groove 2A, the buckle 1 has an inner diameter which is slightly smaller than the outer diameter of the groove of the shaft 2, and is pressure-bonded to the outer surface of the bottom surface where the groove 2A is formed.

Further, when the buckle 1 is attached to the groove 2A of the shaft 2, the buckle clamp dedicated for the buckle is used as described above. A pair of claws that can be freely opened and closed are formed at the front end of the buckle clamp, and the claws are passed through the hole 1B of the buckle 1, and the pair of wide portions 1A and 1A of the buckle 1 are supported by the claws. open. Therefore, when the buckle 1 is attached to the groove 2A of the shaft 2, the pair of claws of the buckle clamp are passed through the pair of holes 1B of the buckle 1, and the buckle 1 is taken by the buckle clamp. After opening a pair of claws, the spacing between the pair of wide portions 1A, 1A of the buckle 1 is slightly extended, the buckle 1 is passed through the front end of the shaft 2, and the claws are buckled at the groove 2A. The hole 1B of the ring 1 is removed and the buckle 1 is mounted on the shaft 2.

However, the hole 1B in which the shaft diameter becomes small is also small as the inner diameter of the buckle 1 becomes smaller. Therefore, it is difficult to attach the buckle 1 to the shaft 2 by using a buckle clamp, so that the buckle is difficult. The ring clamp clamps the buckle 1 and causes the buckle 1 to be broken by the buckle clamp, or the expansion of the buckle 1 due to the operation of the buckle clamp will be damaged, causing the buckle 1 itself to become unusable. . That is, the mounting work of the buckle 1 by the buckle clamp becomes difficult as the buckle 1 becomes smaller.

The present invention has been made in order to solve the above problems, and an object of the invention is to provide a buckle attachment tool that can easily and easily mount a buckle to a shaft even if the buckle is small.

The tool for attaching a buckle according to the first aspect of the present invention is the tool used for attaching the buckle to the shaft, and the tool body includes a tool body and a rod shape having a recessed portion at the tip end; The elastic member is housed in the recessed portion of the tool body, and the magnet is superposed on the upper surface of the elastic member and housed in the recessed portion, and the outer peripheral edge portion thereof is in contact with the locking portion that protrudes inward from the open end of the recessed portion. And the above-mentioned buckle is adsorbed to the front end surface of the tool body by the magnet.

In the invention of the first aspect of the invention, the elastic member and the magnet are detachably attached to the recessed portion. .

In the invention of the first aspect or the second aspect of the invention of the present invention, the elastic member is formed of rubber.

According to the present invention, it is possible to provide a buckle attachment tool which can easily and easily mount a buckle to a shaft even if the buckle is small.

Hereinafter, the buckle attachment tool according to the present invention will be described based on the embodiments shown in Figs. 1 and 2 . Further, the same or corresponding portions as those described above are denoted by the same reference numerals to explain the present embodiment.

The buckle mounting tool 10 of the present embodiment includes, for example, a tool body 11 having a rod shape having a recessed portion 11A at its distal end, and an elastic member 12 housed in a recessed portion of the tool body 11 as shown in Fig. 1 . The inside of the 11A and the magnet 13 are superposed on the upper surface of the elastic member 12 and housed in the recessed portion 11A, and the outer peripheral edge portion thereof elastically contacts the locking portion 11B that protrudes inward from the open end of the recessed portion 11A. This is used when the buckle 1 is attached to the shaft 2 (refer to Fig. 2).

The buckle mounting tool 10 of the present embodiment can be applied to, for example, an inner diameter A small buckle of 2.7 mm to 3.7 mm is available, and a plurality of types can be prepared according to the size (inner diameter) of the buckle 1. The buckle attachment tool 10 can be used even in the case of a large buckle, but a buckle clamp of the prior art can also be used in this case.

For example, as shown in FIG. 1, the tool body 11 includes a rod-shaped body 111 made of metal and a metal case 112 that houses and covers the body 111. The front end portion of the body 111 is formed into a tapered surface, and a recessed portion 11A is formed on the front end surface. A flange-shaped locking portion 11B that protrudes from the open end of the recessed portion 11A of the body 111 is formed at the tip end of the tapered surface of the outer casing 112, and the locking portion 11B prevents the magnet 13 from being ejected from the recessed portion 11A. In other words, the magnet 13 elastically contacts the locking portion 11B by the elastic force of the elastic member 12 and by the outer peripheral edge portion. Although not shown, the outer casing 112 is divided into two parts, for example, and can be integrally joined by screws or the like. Alternatively, there is no outer casing 112. In this case, an annular member may be joined to the open end of the recessed portion 11A of the body 111, and the annular member may be formed as the locking portion 11B.

In the buckle mounting tool 10 of the present embodiment, since the magnet 13 is disposed on the distal end surface thereof, the buckle 1 can be adsorbed and held by the buckle mounting tool 10 by the magnet 13 as shown in Fig. 1 .

Next, a method of attaching the buckle to the shaft using the buckle attachment tool 10 will be described with reference to FIGS. 2(a) to (c).

First, when the front end surface of the buckle attachment tool 10 is brought close to the buckle 1, the buckle 1 is attracted to the front end surface of the buckle attachment tool 10 by the action of the magnet 13. Here, the center of the buckle 1 is as shown in FIG. Align the center of the front end of the buckle mounting tool 10. Since the inner diameter of the buckle 1 is slightly smaller than the outer diameter of the groove of the shaft 2, when the buckle 1 is attached to the shaft 2, the pair of wide portions 1A of the buckle 1 must be opened. 1A.

Therefore, as shown in Fig. 2(a), the front end surface of the buckle attachment tool 10 faces the end surface of the shaft 2, and as shown in Fig. 2(b), when the inclined buckle mounting tool 10 makes the magnet 13 After contacting a part of the front end surface of the shaft 2 and pressing the shaft 2, the magnet 13 is pressed into the recessed portion 11A of the tool body 11 against the elastic force of the elastic member 12, so that a part of the buckle 1 reaches the groove 2A of the shaft 2. .

In this state, as shown by the arrow in Fig. 2(b), when the buckle attachment tool 10 is tilted to rotate along the outer circumference of the end surface of the shaft 2, the buckle 1 is slowly opened and lowered. Slowly embedded in the groove 2A of the shaft 2. When the buckle mounting tool 10 is rotated about the shaft in a tilted state, the entire circumference of the buckle 1 will be embedded in the groove 2A of the shaft 2, and the buckle 1 is attached to the groove of the shaft 2 as shown in (c) of the figure. Inside the slot 2A. When the buckle 1 is mounted in the groove 2A of the shaft 2, the buckle mounting tool 10 can be removed from the shaft 2 as shown in (c) of the drawing, and the mounting work of the buckle 1 on the shaft 2 is completed. At this time, the buckle 1 is firmly pressed into the groove 2A by being attached to the groove 2A of the shaft 2.

As described above, the buckle attachment tool 10 includes the tool body 11 and a rod shape having a recessed portion 11A at the distal end thereof, and the elastic member 12 is housed in the recessed portion 11A of the tool body 11. And the magnet 13, overlapping the upper surface of the elastic member 12 and The outer peripheral edge portion is housed in the recessed portion 11A and elastically contacts the locking portion 11B that protrudes inward from the open end of the recessed portion 11A. Therefore, when the front end surface of the buckle attachment tool 10 is brought into contact with the target buckle 1 , the buckle 1 is sucked by the magnet 13 and held by the front end surface of the buckle attachment tool 10 . When the buckle mounting tool 10 is tilted and the magnet 13 is pressed against the end face of the shaft 2, the magnet 13 enters the recess 11A against the elastic force of the elastic member 12 and causes a part of the buckle 1 to reach the groove 2A of the shaft 2. . The buckle mounting tool 10 is maintained in an inclined state so as to be in contact with the end surface of the shaft 2, and only one circumference is passed along the outer circumference of the end surface, and the buckle 1 can be slowly opened and surely mounted in the groove 2A.

That is, according to the present embodiment, the buckle 1 can be attached to the front end surface of the buckle installation tool 10 only by attaching the buckle attachment tool 10 to the buckle 1, and the buckle 1 is attached to the groove of the shaft 2. When the groove 2A is tilted in the groove 2A and the magnet 13 is pressed against a part of the end surface of the shaft 2, the buckle 1 can be simply wound along the outer circumference of the end face by the inclined buckle attachment tool 10 It is surely mounted to the groove 2A of the shaft 2. Therefore, there is no such thing as a buckle of a conventional technique that damages the buckle 1 and flies or excessively expands the buckle 1 to damage the elastic force.

Further, the present invention is not limited to the above-described embodiment, and various constituent elements can be appropriately modified in design according to requirements. For example, in the above-described embodiment, the metal body is described. However, the tool body is not limited to a metal or a synthetic resin product as long as the function of the magnet is not impaired. Further, the elastic member is not limited to a rubber material, and a spring such as a coil spring may be used.
