Description

[Detailed description of the invention] The present invention relates to a hose band tightening operation device.
In particular, even if the diameter of the hoses varies and the ring diameter of the tightening band changes accordingly,
By making it sufficient to always apply a constant amount of slight tightening operation without being influenced by this, the work efficiency is significantly improved. In order to maintain a stable and solid tightened state that never loosens even when subjected to natural external forces such as In a hose band tightening operation device that constricts the ring diameter of the band by screwing together an enclosed female threaded body and using one of them as a rotating operation handle, the female threaded body is particularly connected to the inner wall surface of the case. It is divided into a plurality of pieces that are tapered-fitted and can only be moved, and the split female threaded body is always pressed and biased in the direction of strengthening the threaded connection with the female threaded body by a common spring material, and the above-mentioned handle is It is characterized in that it is set so that it is pushed along the screwing axis while resisting the spring material to move the female and male screw bodies relatively and release the screwing.

With this configuration, even if the male threaded body is longer than necessary, you can simply push the operating handle all the way to the end in one go without having to turn it one by one from the beginning to the end, and turn it only a few times.
Despite being able to quickly tighten and secure hoses, and being easy to operate,
Once tightened, the female threaded body is pressed in the direction of strengthening the threaded connection with the male threaded body by the spring force, so it will never loosen even if subjected to vibrations or shocks, and will last for a long time. Furthermore, since the female threaded body is enclosed within the case, it is effectively prevented from getting caught in foreign matter or getting dust attached to the male threaded body. become.

The configuration of the present invention will be specifically described below based on the illustrated embodiment. In Figs. 1 and 2, reference numeral 1 denotes a freely bending tightening band of a fixed length, which is molded from a synthetic resin material into a semicircular cross section.
The convex curved surface has a screw thread in advance, so while the flat back surfaces are joined together,
When the band 1 is bent into a ring shape, a male threaded body 2 in the shape of a circular shaft is formed, rising from the ring portion. Reference numeral 3 denotes a synthetic resin base that is inserted and assembled from the formed male threaded body 2 into the band 1, and together with the ring portion of the band 1, it comes into close contact with the hose H and tightens it.

Reference numeral 4 denotes a rotary operation handle that shrinks and deforms the ring diameter D of the band 1 while pushing the base 3, and is assembled from synthetic resin parts as follows. That is, in Figs. 3 and 4 which clarify this, 5 is a cylindrical case with anti-slip uneven stripes arranged on its surface, and in the center of the case there is a truncated cone-shaped female threaded body housing extending from the tapered wall surface. Chamber S is open. Reference numeral 6 denotes a split female threaded body housed in the storage chamber S, which moves toward and away from the male threaded body 2 along the tapered wall surface. In this point,
In the figure, the female screw body 6 is divided into a pair of two pieces, but of course it may be equally divided into a plurality of more pieces.

Further, 7 partitions the divided female screw bodies 6 from each other,
This is a regulating wall that restricts the rotational ability of the case 5, and is integrally protruded from the tapered wall surface of the case 5 in the centripetal direction. Reference numeral 8 denotes a coil spring that constantly presses and biases all of the split female screw bodies 6 in the advancing direction to screw them into male screw body 2 of the band 1, and 9 denotes a storage chamber S.
This cap plate also serves as a retainer for the spring 8, and is integrally bonded to the large open end of the case 5 while utilizing its tapered wall surface.
Even if the female threaded body 6 moves, it goes without saying that a plurality of female threaded bodies 6 are still kept partitioned by the regulating wall 7, and an elastic material may be enclosed in place of the coil spring 8.

Such a handle 4 is removably inserted into the axial male threaded body 2 of the band 1 through circular holes 10 and 11 opened in the case 5 and the cap plate 9, respectively, and is in the inserted and assembled state. Under this condition, the split female threaded body 6 is screwed into the male threaded body 2, so that the ring diameter D of the band 1 can be rotated to contract. Since the divided female threaded body 6 is always urged forward in the direction of strengthening the threaded connection with the male threaded body 2 by the spring 8, it does not accidentally return and rotate, and the hoses H can be tightened stably and robustly. It can be kept in a fixed state.

However, when inserting the male threaded body 2 into the male threaded body 2, if the handle 4 is forcibly pushed in without rotating, the split female threaded body 6 will not be able to rotate relative to the case 5. As shown in FIG. 5, it moves along the tapered wall surface of the storage chamber S while resisting the spring 8, and is retracted from the male threaded body 2, so that the threaded engagement is released. In other words, when the threaded distance from the tip of the male threaded body 2 to the final tightening position of the handle 4 is long, there is no need to turn the handle 4 each time on the way, just push it in. That's enough.

In the basic example shown in FIGS. 1 to 5 above, the male threaded body 2 is directly engraved on the tightening band 1, and with this as the fixed side, the female threaded body 6 screwed thereon is rotated by the handle 4. However, instead of this, modifications such as those shown in FIGS. 6 to 8 may be adopted.

That is, in this modification, the case 5 containing the split female screw body 6 as described above is fixed to the bent end of the tightening band 1 which is wound and bent into a ring shape from a metal wire, and this is screwed together. The male screw body 2 is used as a bolt and is replaced by a rotation operation handle 4 for contracting the ring diameter of the tightening band 1. Even with this, handle 4
If it is pushed in without turning, the threaded engagement will be released as if the split female threaded body 6 is retracted from the male threaded body 2, so it can be said that the structure is substantially the same as the above basic example, and it is the same as the basic example. You can expect effects and effects. Therefore, the parts in FIGS. 6 to 8 are made of metal, although the same reference numerals as those in FIGS. 1 to 5 are used and detailed explanation thereof is omitted.

As described above, the hose band tightening operation device according to the present invention screws together the male threaded body 2 provided on the tightening band 1 side and the female threaded body 6 enclosed in the case 5 side, In a device for contracting the ring diameter D of the band 1 by using one of them as a rotating operation handle, the female threaded body 6 is divided into a plurality of pieces that can only be moved while taperingly fitting with the inner wall surface of the case 5, A plurality of the pieces are constantly pressed and biased in the direction of strengthening the screw engagement with the male screw body 2 by a common spring material, and the plurality of pieces are forcibly pushed in along the screw axis while resisting the biasing force, The configuration is such that the female and male threaded bodies 2 and 6 are unscrewed by moving relative to the male threaded body 2, so even if the male threaded body 2 is longer than necessary, the operating handle 4
The hoses H can be tightened and fixed with high efficiency by pushing the hoses all the way to the end at once without having to turn them from the beginning to the end, and turning them only a few times. In other words, the diameter dimensions of the hoses H are different, and the ring diameter D of the tightening band 1 is
Even if the size changes, the hoses H can always be tightened and loosened with ease.

Furthermore, although it is easy to operate, once it has been tightened, the female threaded body 6 is pressed in the direction of strengthening the screw connection with the male threaded body 2 by the spring force, so it is susceptible to vibrations, etc. It never loosens even when subjected to natural external forces, and can maintain a stable and solid tightened state over a long period of time. In addition, since the female threaded body 6 is enclosed within the case 5, there is no possibility of foreign matter getting caught in the threaded part with the male threaded body 2, and there is no adhesion of dust, etc., which has the practical benefit of not damaging its appearance. , it is recognized as a convenient device in terms of handling.
