Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a hose clamp attaching / detaching jig, and more specifically, it enhances the ease of attaching / detaching a wire type hose clamp.

[0002]

[Prior art]

 As shown in Fig. 5, when connecting the pipe 5 by inserting it into the elastic tube 6, tighten the hose clamp to prevent liquid leakage from the fitting part of the pipe and the elastic tube and to prevent the elastic tube from coming off. To wear.

As the hose clamp, there are a wire type hose clamp having a knob 7 for facilitating attachment and detachment as shown in FIGS. 6a and 6b, and a mechanical type hose clamp as shown in FIG. 6c.

[0004]

[Problems to be solved by the device]

 However, in the mechanical hose clamp as shown in FIG. 6c, compared to the wire type hose clamp, it takes more time to attach and detach, and the working efficiency is poor.

In a wire type hose clamp having a knob 7 for facilitating attachment and detachment as shown in FIG. 6b, the knob 7 can be fastened by pinching the knob 7 with a finger. However, since the tightening force of the hose clamp is required to be strong for reasons such as liquid leakage prevention, even if the knob 7 is formed, it is sometimes necessary to use a jig. In this case, the upper portion of the knob 7 is sandwiched by a substitute jig such as pliers. However, the upper part of the knob 7 is curved and cannot be held firmly by the substitute jig, which makes the work difficult.

On the other hand, the wire-type hose clamp shown in FIG. 6a does not have the knob 7, so that the wire-type hose clamp is easier to manufacture than the one in which the knob 7 is formed, and as a result, is advantageous in cost. For this reason, wire-type hose clamps that do not have the knob 7 are widely used. However, when tightening such a wire-type hose clamp using a jig, the knob part 8 is to be pinched by a pinching part such as pliers, but since the pinch part 8 is columnar, it is difficult to pinch it and force it to pinch it. However, the knob 8 is often disengaged from the holding portion of the jig, and there is still a problem in workability when a large amount of fastening processing is performed.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a plier type hose clamp capable of easily attaching and detaching a so-called wire type hose clamp. It is to provide a detachable jig.

[0008]

[Means for Solving the Problems]

 Therefore, a pliers-type hose clamp attachment / detachment tool that is characterized in that a grip portion, a support shaft, and a holding portion are provided, and a wire-type hose clamp clamp fitting groove is formed in the holding portion, the conventional problems are solved. It is a solution.

[0009]

[Action]

 Conventionally, there is no attachment / detachment jig dedicated to wire type hose clamps, so when tightening with a substitute jig such as pliers, the knob part is columnar, so it is difficult to pinch it with a jig, and if you try to force it, The knob part came off and it took time to tighten it. Further, when a large amount of tightening treatment is performed, there is still a problem in workability. However, if a pliers-type hose clamp attachment / detachment with a wire-type hose clamp knob fitting groove formed in the holding part is used, the wire-type hose clamp knob part can be completely fitted and held by the fitting groove. The wire-type hose clamp can now be easily attached and detached without the knob part coming off from the holding part when attaching or detaching.

【Example】

 Hereinafter, the present invention will be described in detail with reference to the drawings showing an embodiment.

FIG. 1 is a view showing a plier type hose clamp attaching / detaching jig according to an embodiment of the present invention. In the figure, 1 is a grip portion, 4 is a holding portion integrally formed with the grip portion, and 12 is a support shaft. FIG. 2 shows a three-sided view of the holding portion 4, and 2a and 2b are fitting grooves formed in the holding portion, respectively, and the tip upper cross section 10 of the wire-type hose clamp knob portion 8 and This is for fitting the knob body 9 together.

In this example, the fitting groove 2a and the fitting groove 2b are formed in a V shape, and the fitting groove 2a is formed deeper and larger than the fitting groove 2b. The shape of the fitting groove is not limited to this, and may be U-shaped as shown in FIG. 3a or semicircular as shown in FIG. 3b. However, from the viewpoint of easy formation, a V-shaped one is preferable.

In this embodiment, the hose clamp attaching / detaching jig is made of metal, and after the fitting groove is formed, the fitting groove portion is hardened to increase its hardness. The material for forming the hose clamp attaching / detaching jig is not necessarily limited to metal. Further, the shape of the hose clamp attachment / detachment jig main body is not limited to the illustrated one.

FIG. 4A is a view showing a state in which a wire type hose clamp is attached using the hose clamp attaching / detaching jig. In this figure, 5 is a pipe, 6 is an elastic tube, 8 is a wire type hose clamp knob, 9 is a body of the knob, 10 is a cross section of the upper end of the knob 8, and 11 is a wire hose clamp. As shown in FIG. 4a, the grip portion 1 of the hose clamp attaching / detaching jig is grasped, the fitting groove 2a is fitted in the upper end cross section 10 of the knob portion 8, and the wire type hose clamp knob portion 8 is gradually sandwiched. Then, the knob body 9 is fitted into the fitting groove 2b. If the knob portion 8 is completely sandwiched, the inner diameter of the wire type hose clamp fastening portion can be increased as shown in FIG. 4b, and the wire type hose clamp 11 can be easily attached and detached.

In the case of this embodiment, the fitting groove 2a for fitting the upper cross section 10 of the knob portion is formed deeper than the fitting groove 2b for fitting the body portion 9 of the knob portion. 9 can be sandwiched in a stable fitted state. Therefore, even when the working space is small and the jig cannot be used upright as in the above embodiment, the fastening process can be performed with the jig lying down.

[0016]

[Effect of device]

 As described above, the present invention comprises a grip portion, a support shaft, and a holding portion, and the holding portion is formed with a wire-type hose clamp knob portion fitting groove. The present invention relates to a detachable jig.

According to this, not only can the attachment / detachment of the wire type hose clamp, which has been conventionally performed by using a substitute jig, be very easy, but also when a large number of wire type hose clamps are tightened and fastened, You can work very efficiently. Therefore, the practical value of this device is great.
