DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the preferred embodiments of the present invention will be described with reference to the accompanying drawings, where like reference numerals refer to like parts, and detailed description thereof will be omitted.

1 is a perspective view showing a hose clamp fastening tool according to a preferred embodiment of the present invention, Figure 2 is a perspective view showing the separation of the main part of Figure 1, Figures 3 and 4 is a tool bit before and after fastening the hose clamp bite It is a sectional view of the state.

The hose clamp 100 according to the embodiment of the present invention has a first body portion 110 having a curved surface in an arc shape, and the second body portion 120 extending in the circumferential direction from the first body portion 110. And a locking loop 130 provided on the first body portion 110 and a locking jaw 140 provided on the second body portion 120.

The first body part 110 is provided with a receiving hole 113 long in its extending direction, and is provided with a first bent part 111 bent inclined outward with respect to the circumference. The second body portion 120 has a width corresponding to the receiving hole 113 so as to be accommodated in the receiving hole 113, and has a second bent portion 121 that is bent outwardly with respect to the circumference. .

The locking loop 130 is disposed adjacent to the bent portion of the first bent portion 111 and connects the divided portion by the formation of the receiving hole 113. That is, the first accommodation hole 113a into which the second bending portion 121 enters and exits is divided into a second accommodation hole 113b which is a locking hole 113b to which the locking protrusion 10 described later is engaged.

The locking jaw 140 is the elastic deformation of the first body part 110 and the second body part 120 while the first bent part 111 and the second bent part 121 are approaching each other. The latch loop 130 is caught. As described above, when the first bent part 111 and the second bent part 121 are in a mutually approaching position due to the locking of the locking loop 130 and the locking jaw 140, the first body part 110 is located. ) And the hose (H) is disposed inside the second body portion (120).

Therefore, in the state in which the inner diameter of the clamp 100 is extended, the elastic restoring force of the first and second body parts 110 and 120 acts on the central portion of the locking loop 130, whereby the elastic restoring force of the locking loop 130 is applied. It is suppressed to act out of the center portion, and as a result, deformation of the clamp 100 is suppressed.

As described above, the tool 1 for releasing the clamp 100 in the locked state between the locking loop 130 and the locking step 140 will be described.

The tool 1 is composed of a locking projection 10, a pusher 30, and an actuator 50 that applies a push force to the pusher 30.

The locking protrusion 10 is inserted into and caught by the locking hole 113b of the first bent part 111.

The push part 30 pushes the second bent part 121.

That is, the upper surface 30a of the push part 30 is pushed in a state in contact with the end 123 of the second bent part 121.

As such, when the locking protrusion 10 is hooked to the locking hole 113b and the pusher 30 is pushed, the second bending portion 121 is pushed into the clamp 100 at the receiving hole 113a and thereby The locking jaw 140 is released from the locking loop by being pulled out of the locking loop 130.

Therefore, the tool 1 of the present embodiment can work by holding the clamp 100 by the locking projection 10 and the push portion 30, and temporarily clamp the clamp 100 to the hose H by bonding or the like. There is no need to support it.

In addition, the existing clamp 100 can be applied as it is without the need to form a separate hole or groove.

On the other hand, the push portion 30 is preferably formed with a locking step jaw 31 is caught by the end 123 of the second bent portion 121.

The latching step 31 prevents the second bent portion 121 from being pushed outward (that is, pushed in the direction in which the bent portion is unfolded) when the push force is applied to the end portion 123.

Accordingly, the bending state of the second bent portion 121 may be maintained as it is, and the push force may be transmitted to the second bent portion 121 as it is to immediately release the clamping state of the clamp 100.

Actuator 50 is a mechanism that can push the push unit 30 is sufficient, for example, it can be implemented as a cylinder drive mechanism as in this embodiment.

The actuator 50 is largely comprised of a cylinder 60 and a cylinder drive unit 70.

The cylinder 60 is comprised from the push shaft 61 which pushes the said push part 30, and the hollow guide shaft 63 which guides the said push shaft 61 so that lifting and lowering is possible.

The push part 30 is screwed to the front end of the push shaft 61.

The locking projection 10 is supported by the screw fastening at the tip of the guide shaft 63. That is, the cap 65 is fastened to the upper end of the guide shaft 63 at the lower end of the locking protrusion 10.

The cylinder drive unit 70 includes a body 73 having a guide pin 71 installed at a lower side of the push shaft 61, a long hole 72 for guiding the guide pin 71 in a push direction, and a first one. First and second links 78 and 79 pivotably connected to the handle 75 and the second handle 76, the guide pin 71 and the first and second handles 75 and 76. Consists of

The guide pin 71 is vertically coupled to the push shaft 63 protruding from the lower end of the guide shaft 63.

Body 73 is screwed to the lower end of the guide shaft (63).

The handle support piece 74 which supports the handles 75 and 76 so that rotation is possible in the upper side of the body 73 is formed.

In addition, the body 73 is formed with a long hole 72 for guiding the guide pin (71).

The upper sides of the handles 75 and 76 are pivotally supported by the handle support piece 74 by a hinge hole.

One end of the first and second links 78 and 79 is rotatably supported by the guide pin 71 and the other end of the first and second links 78 and 79 in the lower side of the handles 75 and 76.

In addition, one end of the first and second links 78 and 79 is inclined to be disposed above the other end in the push direction.

With this configuration, the guide pins 71 are guided along the long holes 72 in the push (up) direction by the first and second links 78 and 79 by holding the handles 75 and 76 and pressing them. . Therefore, when the guide pin 71 is raised, the push shaft 61 is also raised, so that the push part 30 pushes the end 123 of the second bent part 121.

Then, the second bending portion 121 is pushed up into the first accommodation hole (113a) while the locking jaw 140 is released to the locking loop 130. At this time, the locking protrusion 10 is held in the state that is continuously inserted into the locking hole (113b).

Of course, when the push unit 30 is at the highest position, the upper surface 30a of the push unit 30 is located at a position higher than the locking protrusion 10, as shown in FIG. The first receiving hole 113a can be reliably pushed into the inner diameter of the clamp 100.

In addition, a spring 80 is preferably interposed between the push shaft 61 and the guide shaft 63.

The upper end of the spring 80 is supported by the cap 65, and the lower end of the spring 80 is supported by the seating jaw 62 of the push shaft 61.

Therefore, when the handles 75 and 76 are released, the push part 30 returns to the original position by the elastic force of the spring 80.
