The Applicant first describes here that the adjectives relating to directionality, such as top, bottom, left, and right, as used throughout the specification, are based on the directions in the drawings of the present invention.

Referring to FIG. 1 , a cable fixing device 10 according to a preferred embodiment of the present invention mainly includes a base 20 and a cable fixing block 30 .

As shown in FIGS. 1 and 2, the base 20 has a body portion 21, a tail portion 23, and a long slot hole 25. The body portion 21 is provided with an external thread in this example, and the tail portion 23 is integrally connected to the body portion 21, and the long slot hole 25 extends through the body portion 21 and the tail portion 23. Secondly, the long slot 25 has a straight section 251 corresponding to the body 21, and a circular arc segment 253 and an open section 255 corresponding to the tail portion 23, the open section 255 is oriented toward the straight section The tapered shape of the 251 direction is tapered. Further, in the embodiment, the intersection of the circular arc segment 253 and the opening segment 255 is curved.

Referring to FIGS. 1 and 2 again, the cable fixing block 30 has a substantially spherical ball portion 31, a vertical portion 37 integrally connecting the ball portion 31, and a ball portion 31 and a vertical portion thereof extending in the axial direction thereof. The constant hole 33 of the straight portion 37 and an eccentric hole 35 adjacent to the through hole 33. Next, the through hole 33 has a tapered section 331 and a straight section 333 which is tapered in a direction opposite to the opposite direction of the ball portion 31. The straight section 333 and the tapered section 331 The body is integrally joined, and in this example, the intersection of the straight section 333 and the tapered section 331 is curved. Furthermore, as shown in FIG. 3A, the outer diameter of the vertical portion 37 of the cable fixing block 30 is smaller than the diameter of the straight portion 251 of the long slot hole 25 of the base, and the outer diameter of the ball portion 31 is larger than the long slot. The aperture of the opening section 255 of 25, The curvature of the ball portion 31 is less than or equal to the curvature of the arc segment 253 of the long slot hole 25, and the aperture of the through hole 33 is smaller than the aperture of the opening segment 255 of the slot hole 25.

When assembling the cable fixing device 10 of the present invention, as shown in FIG. 3A, since the outer diameter of the vertical portion 37 of the wire fixing block 30 is smaller than the diameter of the straight portion 251, the outer diameter of the ball portion 31 is larger than the outer diameter of the wire portion 31. The aperture of the opening section 255, and the ball portion 31 has a curvature smaller than or equal to the curvature of the arc segment 253, so that the cable fixing block 30 can be stably accommodated in the long slot 25 of the base 20, and The ball portion 31 is placed on the circular arc segment 253, and a gap of a certain width is formed between the vertical portion 37 of the cable fixing block 30 and the straight portion 251 of the long slot hole 25, so that the cable fixing block 30 is fixed. It is possible to swing in the long slot 25 . In addition, since the through hole 33 of the cable fixing block 30 has an aperture smaller than the aperture of the opening section 255, the opening section 255 can provide sufficient activity of the cable S after a cable S is fixed to the cable fixing block 30. space.

When the cable fixing device 10 of the present invention is applied, as shown in Fig. 4, the cable fixing device 10 can be mounted on a swingable object, in this example, capable of swinging around its axis. The control panel C is exemplified, but it is not limited thereto, and the cable fixing device 10 of the present invention is applicable to any object capable of swinging.

In practical application, taking the arm H3 and the arm H4 as an example, a steel cable S first passes through the through hole 33 of the cable fixing block 30 from bottom to top, and then the cable S is bent to pass through the eccentric hole. 35. One end of the cable S is fixed to the cable fixing block 30 by, for example, welding. Thereafter, the wire fixing block 30 to which the wire S is fixed is housed in the long slot 25 of the base 20, and the body portion 21 of the base is fixed to the arm H4. The other end of the cable S that has passed through the opening section 255 is fixed to the cable fixing block 30 of the other cable fixing device 10 of the arm H3 in the same manner. Thus, when the arms H3, H4 are oscillated, as shown in FIG. 3B, the cable fixing block 30 will drive the cable S to swing relative to the base 20 in the long slot 25 without causing the cable S. The bending of the wire rope fixing device 10 of the present invention can effectively avoid the problem of the steel wire broken due to the reciprocating oscillation of the control disk C. In addition, in this example, the open section 255 of the long slot 25 of the base 20 and the tapered section 331 of the through hole 33 of the cable fixing block 30 are disposed to taper toward the body 21 of the base. In an aspect, the intersection of the open section 255 and the arc segment 253 and the intersection of the tapered section 331 and the straight section 333 are curved, that is, a lead angle is provided, so that the cable can also be protected. S will not be cut when it is activated.

In summary, since the cable fixing device 10 of the present invention has the base 20 and the cable fixing block 30 as described above, when the cable S is fixed to a swingable object through the cable fixing device 10 of the present invention The cable fixing block 30 can drive the cable S to swing relative to the base 20 that swings with the object to prevent the cable S from being bent, thereby preventing the cable S from being broken.
