When the tube is connected to a movable device, the movement of the tube cannot be absorbed, which is a disadvantage.

Furthermore, the example shown in Fig. 6(b) is a device that is held using an attachment device 3 formed with four parts that match the outer diameter of the tube, and the tube is held by pushing the tube into the recess from the opening side of the four parts. Hold. This attachment device 3 has the advantage that the tube can slide inside the recess, but if the tube connected to a mechanical device makes a large movement such as bouncing, the tube cannot be pulled out from the openings in the four parts. The tube may come out and the tube may not be held completely.

SUMMARY OF THE INVENTION The present invention has been devised to solve the above two problems.The purpose of the present invention is to securely hold the tube without it coming out from the mounting device, and to hold the tube in the axial direction of the tube.

It is characterized by being freely supported, and is also provided with locking protrusions of a commonly standardized diameter size on supports that support piping tubes with different diameters and different numbers of piping tubes. In addition, the attachment member is formed of a flexible material, and has a plurality of insertion holes into which the locking projections are inserted, and a fastening projection that fits into the insertion holes is formed on the base body. The method of holding the piping tube includes inserting the piping tube into the support of the piping tube gripper, and fitting the fastening protrusion into the insertion hole to connect the piping tube. The piping tube is gripped by fitting the locking protrusion of the support into the fitting hole on the outer surface of the cable tie, and the piping tube gripping tool has a piping The tube is inserted into the tube, and the locking protrusion of the support body is fitted into the fitting hole on the inner surface of the binding band to which the fastening protrusion is fitted into the fitting hole, thereby gripping the piping tube. Features.

(Function) In the plumbing tube gripping tool, the plumbing tube is inserted into the ring-shaped part by widening the crack 1, and the fitting hole provided in the cable tie is inserted by aligning the half-shaped locking protrusions. By fitting, the gripping tool is attached, and the piping tube is thereby gripped.

(Embodiments) Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 is an explanatory diagram showing an embodiment of a piping tube gripping tool and a binding band according to the present invention.

In the figure, 10 is an example of a gripper that grips one tube, and ]-2 is an example of a double gripper that grips two tubes together.

The support 11 of the gripping tool 10 is formed in a half-ring shape in which a tube insertion hole with a diameter matching the tube outer diameter is formed, and the support 13 of the two series of gripping tools 12 is formed with two tubes. It is formed in the shape of a half-split oval ring with two tube insertion holes through which the tube is inserted.

A half-shaped split 14 is formed on the periphery of the support 11.13 of the gripper 10.12, and by opening the split 14, the tube can be inserted into the tube insertion hole. 1 can be inserted.

Further, reference numeral 16 denotes a locking protrusion that is formed to protrude from the outer surface of the crack 14 portion, and is formed in half on each outer surface of the crack surface with the crack 14 in between. The locking protrusion 16 formed in half has a nail shape with an umbrella portion at the top when the cracks 14 are aligned. Note that the umbrella portion of the locking protrusion 16 is provided with a non-return taper in which the diameter of the upper portion is reduced.

Further, in the figure, 20 is a binding band for fixing the gripping tools 10 and 12. This binding band 20 is provided with a plurality of insertion holes 22 into which the locking projections 16 are fitted.

The gripping tools 10 and 12 can hold the tube 1 by inserting it into the tube insertion hole, and are fixed to the binding band 20 by fitting the locking protrusion 16 into the insertion hole 22 to hold the tube 1.

24 is a fastening protrusion provided at one end of the coupling band 20. The fastening protrusion 24 is provided with a non-return taper on the umbrella portion, similar to the locking protrusion, and is formed in a size that fits into the insertion hole 22 provided in the binding band 20.

In the above embodiment, the gripping tool 10 that grips one tube and the gripping tool 12 that grips two tubes are shown, but of course, three or more gripping tools that grip three or more tubes can also be formed in the same way. can do. In addition, gripping tools with different inner diameter sizes can be prepared to match various tube sizes.

Further, the size of the locking protrusion 16 may be determined in relation to the insertion hole 22 provided in the binding band 20, but it is easy to use.
Second, it is preferable that the sizes of the locking protrusions formed on the various gripping tools and the insertion holes of the binding bands are made to be the same size.

Further, if the locking protrusion 16 is formed into a nail shape and the insertion hole 22 is formed into a round hole as in the above embodiment, there is an advantage that the gripping tool can be rotated when the gripping tool is attached to the binding band 20. . In addition, depending on the case, the locking protrusion may be formed into a rectangular shape and the fitting hole may be formed into the same rectangular shape so that the gripping tool cannot be rotated in the attached state.

The material of the above-mentioned gripping tool is not particularly limited, but
Since the gripping tools 10, 12 are used to open the crack 14 and insert the tube, they must have some degree of flexibility.

FIG. 2 shows an example in which a tube is attached using the gripper 10 described in 1. In this example, all tubes having the same diameter are fixed to the binding band 20. '' When holding the tube in a double-connected manner, the tube may be inserted into the tube insertion hole of the gripper 10 and the locking protrusion 16 may be fitted into the insertion hole 22 to fix the gripper 10 to the binding band 20. Note that the insertion hole 22 provided in the binding band 20 is also used as a screw hole when attaching the binding band 20, and is used when attaching the binding band 20 to a predetermined position.

In the example shown in FIG. 2, the gripping tool 10 is
By rotating the cable tie 20 while attached to
The tubes can be rotated around the locking protrusion at the top, and the direction in which the tubes are arranged can be changed.

FIG. 3 shows another example of the use of the gripping tool, and in this example, tubes of different diameters, two sets of gripping tools 12, etc. are attached to one binding band 20 in a mixed manner. Since these gripping tools have a common locking protrusion, the tube can be held by fitting the locking protrusion into any fitting hole.

4 and 5 show examples in which the tube is held using a gripper with the cable ties 20 connected in a circular manner. FIG. 5 shows an example in which a gripper is attached to the inner surface of the binding band 20.

The example shown in FIG. 4 can be used when a binding band 20 is wrapped around and fixed to a support, and the example shown in FIG. 5 is useful when holding tubes together.

In addition, in FIGS. 4 and 5, the binding band 20 is connected in a circular shape by fitting the fastening projection 24 into the insertion hole 22. In this example, book binding bands are connected in a circular shape, but depending on the case, multiple binding bands can be connected sequentially to form a circular shape, and of course they may be held in a shape other than circular. . When bending the cable tie 20 into a circular shape in this way,
0 needs to be made of a material with a predetermined flexibility.

It goes without saying that in the examples shown in FIGS. 4 and 5, gripping tools of different diameters or two sets of gripping tools can be used at the same time.

In addition, in the above example, a binding band was used as the attachment member of the gripping tool, but this attachment member is not necessarily limited to a binding band.
It is sufficient that a fitting hole is formed into which the locking protrusion can fit and support the gripping tool, and there are no particular limitations on the number of fitting holes, the arrangement interval, etc.

As mentioned above, the gripper grips the entire outer circumference of the tube while it is fixed to the cable tie, so even if the tube is damaged by the operation of a mechanical device, the tube will not come out of the gripper, making it reliable. It is possible to maintain the

Furthermore, the tube can be moved in the axial direction, and deformation of the tube can be absorbed. Furthermore, since the locking protrusion is provided with a non-return taper, the gripping tool is reliably installed in the insertion hole. Further, when using the gripping tool, the tube can be inserted by opening the crack in the gripping tool, and the locking projection can be fixed simply by fitting into the insertion hole of the binding band, making handling operations extremely easy.

The present invention has been variously explained above using preferred embodiments, but the present invention is not limited to these embodiments.
Of course, many modifications can be made without departing from the spirit of the invention.

(Effects of the Invention) According to the gripping tool of the present invention, the piping tube can be easily inserted into the gripping tool as described above, and the tube can be easily gripped by simply fitting the locking projection into the insertion hole. I can do it. Furthermore, the handling operation is easy.''Secondly, the piping tube can be held securely, and the movement of the tube can be sufficiently accommodated. In addition, by using cable ties as attachments, various types of scale installation are possible.
By standardizing the size of the locking protrusions, even tubes of different diameters can be easily held.
