Turnbuckle {Turnbuckle}

The present invention relates to a turnbuckle, and more particularly, to a turnbuckle that can adjust the tension of the integrated cable.

Turnbuckle refers to a screw part that has a right-handed nut on one end of the turnbuckle body and a left-handed thread on the other end in a straight line. It is used to adjust the distance as the screw rods at both ends get closer to each other or move away from each other by rotating in the direction.

In particular, the turnbuckle is used to bind the fixture by fixing the cable to the screw rods on both sides of the turnbuckle. When fixing the fixture using the turnbuckle, the turnbuckle is subjected to the tension of the cable, in particular the tension is concentrated in the body portion. With the use of turnbuckles, the stress builds up in the turnbuckles and the body part is at risk of fatigue failure.

However, the turnbuckle according to the prior art as described above has a problem in that when the body part is destroyed by fatigue or excessive tension, the cables coupled to both ends of the body are completely separated from each other, thereby releasing the binding of the fixture, thereby causing a safety accident. have.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention. First of all, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals are used as much as possible even if displayed on different drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

The turnbuckle 1 according to an embodiment of the present invention has a left thread on the outer circumferential surface of the turnbuckle 1 through which the inside is penetrated and the right and the left thread are formed inside the both ends, and the right side of the rotary part 10 is moved. The first hook 20 and the second hook 30 having a right screw formed on the outer circumferential surface of the rotating part 10 are largely formed.

Rotating portion 10 is in the form of a female threaded tubular sleeve (sleeve), both ends are formed with a female thread for mounting the first, second hooks (20, 30). Long holes are formed between the female threads formed on both sides of the rotating part 10.

Male threads are formed at one end of each of the first and second hooks 20 and 30, and the first and second hooks 20 are formed with a left screw and a right hook with a second hook 30. When the rotating unit 10 is rotated in one direction while the 20 and 30 are mounted on the rotating unit 10, the first and second hooks 20 and 30 are close to each other, and when the rotating unit 10 is rotated in another direction, the first and second hooks ( 20 and 30 are configured to move away from each other.

The first hook 20 and the second hook 30 are each formed with a conical hole 24 on the opposite side of the threaded side, and the wedge 40 holding the cable 2 is inserted into the conical hole 24. It is settled down. Therefore, in the present invention, both ends of the cable 2 may be supported through the first and second hooks 20 and 30 and the wedge 40.

The wedge 40 has a hollow in which the cable 2 is inserted and gripped, and the wedge 40 holding the cable 2 is seated in the cone 24 of the first and second hooks 20 and 30, respectively. do. In other words, the wedge 40 is inserted into and fixed to the conical hole 24 of the first and second hooks 20 and 30 in a state of biting and fixing one end of the cable 2. The wedge 40 inserted into the conical hole 24 is pressed from the outside to the inside by the tension acting on the cable 2 is gripped by the cable (2) is introduced into the hollow. In other words, when the tension is applied to the cable 2 while the wedge 40 into which the cable 2 is inserted is inserted into the first and second hooks 20 and 30, respectively, the wedge 40 is connected to the first and second hooks ( 20 and 30 move together with the cable 2 in the direction of the vertex of the cone, the side surface of the wedge 40 is coupled to the conical hole 24 and the conical surface of the first and second hooks 20 and 30 by wedge 40 is pressed in the radially inward direction so that the cable 2 is tightly tightened.

Wedge 40 may be formed in a divided form as shown in FIG. That is, the conical wedge 40a may be cut along the cut line 41 of the side bus bar, and thus may be formed of two to four divided pieces 42. The plurality of divided pieces 42 are combined to form one wedge 40a having a conical shape.

On the other hand, the shape of the wedge 40b is not formed in a divided form, as shown in FIG. That is, a single incision 41 is formed integrally over the entire length of the busbar of the conical wedge 40b, and when pressed from the outside, it is configured to be crimped in the radially inward direction to grip the cable.

In addition, as shown in FIG. 5, the wedge 40c may be integrally formed by forming the cut line 41 only at a portion of the bus length although a plurality of cut lines 41 are formed along the bus line.

In addition, the wedge 40 may be configured so that the incision line is not formed, of course.

Hereinafter, the coupling process and the use process of the turnbuckle according to the present embodiment will be described with reference to the above-described components.

A through hole penetrates perpendicularly to an outer circumferential surface of the rotating part 10 in which right and left threaded mountains are formed at both ends. Then, the first hook 20 is coupled to the right hand thread of the rotating part 10, and the second hook 30 is coupled to the left hand thread of the rotating part 10. Both ends of the cable 2 are bitten by the wedge 40 and then both ends of the cable 2 are inserted into the conical holes 24 of the first and second hooks 20 and 30, respectively. By operating the rotary unit 10 in a state where the cable 2 is tied to the fixture, the distance between the two hooks 20 and 30 is adjusted so that the cable 2 is properly tensioned. When the cable 2 is tensioned, the cable 2 wedges as the wedge 40 is inserted into the conical hole 24 of the first and second hooks 20 and 30, respectively, and tightened in the radially inward direction. Strongly bound to 40. The stronger the tension applied to the cable 2, the stronger the wedge 40 penetrates into the conical hole 24, so that the cable 2 is more strongly bound to the turnbuckle 1.

In this way, even though the cable 2 is held in tension by the turnbuckle 1, excessive external force is applied to the turnbuckle 1 so that the rotation part 10 or the hooks 20 and 30 of the turnbuckle 1 are broken. Since the cables 2 are not completely separated from each other, large accidents can be prevented.

In addition, in the present embodiment, the cable 2 formed integrally has been described as being mounted to the turnbuckle 1, but the turnbuckle 1 according to the present invention has both ends of the cable 2 having the interruption portion separated in the same manner as in the conventional method. It is also possible to mount each to the turnbuckle 1. The cable 2 of the separated form is also fixed by inserting and fixing both ends of the cable 2 to the first and second hooks 20 and 30, respectively, while the cable 2 is wrapped around the fixture.
