Description

[Detailed Description of the Invention] This invention relates to a crushing piece of a hook driving machine for holding a hook constituting a male hook and fixing the hook and the pair of hooks together.

As is well known, the pair of hooks consisting of a female 1 and a male 2 are often used to stop clothing from opening, as shown in Figure 1. The male of this species is the second
As shown in the figure, it is composed of a connector 3 and a socket 4, and the connector 3 has a fitting part 5 that is fitted to the female 2 side.
The retainer 4 has a cylindrical engagement portion 8 and a presser portion 9 that presses the sheet S. Therefore, the above-mentioned Genco 3 and Hoso 4 are connected to Hoso 4 as shown in FIG.
The engaging portion 8 is passed through the inner hole 7, the tip is bent, and the tip is engaged with the engaging edge 10 of the crushed inner hole 7, so that they are fixed together via the sheet S.

By the way, for fixing the above-mentioned hooks 3 and bolts 4, a manual, foot-operated, or semi-automatic hook-placing machine is used. For example, as an example, a manual pouring machine is shown in FIG. 4, but on the base 11a,
There is a holding piece 11 for the housing 4 on which the housing 4 is placed, and a driving shaft 14 that can be pushed down by a driving handle 12 against the biasing force of a spring 13 holds the housing 3 and holds the housing 4 at the lower end. A crushing piece 15 for bending and crushing the engaging portion 8 is attached.

The conventional crushing piece 15 has a structure shown in FIG. That is, the cylindrical main body 16 of the crushing piece 15
has a male threaded part 17 for mounting, and a recess 18 for holding the lever 3 is formed on the opposite side, and a crushing metal 19 for bending the engaging part 8 of the retainer 4 is provided in the recess 18. It is protruding and fixed. A split ring 21 is attached to a mounting groove 20 provided on the inner periphery of this recess 18.
By engaging the outer peripheral recess 5a of the fitting portion 5 of the holder 3 with the holder 1, the holder 3 can be held in the main body 16.

By the way, when the above-mentioned conventional crushing pieces are used, the following problems arise.

(1) Fitting Genko 3 into split ring 21 is
hard or soft,
It is not easy to adjust the holding force of Genco 3 and keep it constant.

(2) The upper edge 15a of the split ring 21 is crushed during the pouring work, resulting in a short lifespan of the piece.

(3) Due to reasons (1) and (2), workers are easily fatigued and cannot work continuously for long periods of time, resulting in poor work efficiency.

Therefore, this idea was made in view of the above points, and it is possible to easily attach the genco, maintain a constant holding force, and extend the life of the crushing piece.
To provide a crushing piece for a hook driving machine that can perform continuous work for a long time and improve work efficiency.

Therefore, in order to achieve this purpose, this invention is attached to a hook driving machine, holds a hook constituting the male part of the hook, and inserts the tip of the hook through the hook that is paired with the hook. In a crushing piece of a hook setting machine that fixes the hook and the hook together through a sheet such as cotton cloth, a cylinder made of an elastic material and elastically holding the hook within the inner periphery is provided in the recess of the crushing piece. A lock holding member having a shape of a shape is fitted, and a fitting edge that fits into a fitting groove provided on the inner periphery of the recess is integrally formed on the outer periphery of the holding member. do.

This invention will be explained below with reference to illustrated embodiments.

FIGS. 6A and 6B are cross-sectional views showing one embodiment of the crushing piece of this invention. It has a male threaded part 37 for screwing, and a recessed part 38 is formed in the lower part. A crusher 39 protrudes from the center of the inner bottom of the recess 38 and is fixed with adhesive, for example, and a fitting groove 40 having an inner diameter larger than the inner diameter of the recess 38 is formed on the inner periphery of the inner bottom. It is formed.

On the other hand, the grip holding member 41 that is removably fitted into the recess 38 is made of an elastic material such as plastic and has a cylindrical shape, and is fitted into the fitting groove 40 of the recess 38 on the outer periphery of one side. A fitting edge 42 is formed on the inner periphery of the other side, and a holding edge 43 is formed on the inner periphery of the other side to be engaged with the outer periphery recess 5a of the rod 3. The inner diameter l of this holding edge 43
is smaller than the large diameter L of the fitting portion 5 of the Genco 3. Note that the main body 36 has a through hole 44 for the tightening rod.
is formed.

As shown in FIGS. 7 and 8, let us consider the case where the male hook 2 is made using, for example, the manual hook driving machine shown in FIG. 4.

A tenon 4 passed through a hole in a sheet S of cotton cloth or the like is fitted onto the holding piece 11 on the base 11a, and the driving shaft 1 is
Crushing piece 3 attached to 4 with a tightening rod not shown
5 is fitted with a stick holding member 41, and the stick 3 is fitted into the crushing piece 35 via the holding edge 43 of this stick holding member 41 to securely hold it.

As described above, the bolt 3 and the bolt 4, which are vertically opposed to each other, are fixed together by pressing down the pouring handle 12. That is, the engaging portion 8 of the retainer 4 is inserted into the inner hole 7 of the retainer 3, is bent and crushed by the crusher 39, and is engaged with the engaging edge 10, and the retainer 3 and retainer 4 are integrated with each other via the sheet S. is fixed to.

By the way, the above-mentioned operation is performed repeatedly, and in this case, the attachment of the lever 3 to the crushing piece 35 is facilitated by the lever holding member 41, and a constant holding force can always be obtained. Further, since there is no weak part unlike conventional pieces, there is no fear that the crushing piece 35 itself will be crushed and become unusable even if the pouring work is continued, and continuous work can be performed.

In addition, in the above-mentioned embodiment, a case was described in which a hand-operated hook-driving machine was used; however, the crushing piece of this invention can be used in a foot-operated or semi-automatic hook-placing machine with the same effect and effect. Needless to say, you can obtain

As explained above, according to this invention, the cylindrical support member 41 made of an elastic material is fitted into the recess 38 provided on the bottom surface of the crushing piece 35,
Since the holder 3 is elastically held on the inner circumference of the holder 4, the holder 41 is cylindrical and has a vertically longer structure than the conventional O-ring holding member. The holding power of the crushing piece 35 is also improved, its lifespan is extended, and long-term continuous work is possible without fatigue.
6 is also protected and its deformation is prevented, improving the pouring work efficiency.

Furthermore, the grip holding member 41 has a cylindrical shape, and a fitting edge 42 that fits into a fitting groove 40 on the inner periphery of the crushing piece recess 38 is integrally formed on the outer periphery of the cylindrical shape.
There is no risk of the grip holding member 41 falling off during the work, and the fitting edge 42 is fitted into the fitting groove 40, so the fitting groove 40 is not crushed during the work.
The grip holding member 41 itself is reinforced by the fitting edge 42 and does not deform during use. Furthermore, since the grip holding member 41 is held in a suspended state in the recess 38 of the crushing piece by the above-mentioned fitting edge 42, the outer periphery of the grip holding member 41 and the inner periphery of the recess 38 are connected to each other. It is possible to create a highly elastic shape with a gap provided between the holding edge 43 and the holding edge 43 to be omitted.
