Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cable bracket for holding a cable and supporting it on a pedestal.

[0002]

2. Description of the Related Art In a conventional cable bracket, a cable is sandwiched by a half-cylinder-shaped gripping material and is bolted to a pedestal to support it. In addition, there is also one tightened with a spring interposed.

[0003]

Although the conventional cable bracket is as described above, the one in which the cable is simply clamped cannot cope with the expansion and contraction of the cable cross section, and the gripping force is weak when the cable diameter is reduced. Become. In addition, there is a problem that the structure including the spring or the like has a complicated structure, an uncertain function, and a short life.

The present invention has been made to solve the above problems, and provides a cable bracket which can be flexibly gripped and reliably supported with almost the same force even when the cable expands and contracts. With the goal.

[0005]

A cable bracket according to the present invention is a cable bracket for supporting a cable by tightening a gripping material on a pedestal with a tightening means, and a cable is provided between the gripping material or the pedestal and the cable. A pair of semi-cylindrical bushes, which are elastic bodies and have bellows-like irregularities formed on the inner surface in contact with the intervening bushes, are interposed.

[0006]

The pair of semi-cylindrical bushes of the cable bracket according to the present invention is clamped to the cable by pressing the gripping member to the pedestal by the tightening means.
Since this bush is a semi-cylindrical elastic body having bellows-shaped irregularities formed on the inner surface in contact with the cable, the peaks of the bellows-shaped irregularities are compressed to some extent and elastically deformed to flexibly contact the cable. Therefore, even if the cable expands and contracts, the vicinity of the mountain on the inner surface of the bush elastically deforms in response to the expansion and contraction, and the cable is always flexibly pressed and gripped with substantially the same force. Further, since the concavo-convex shape has a large frictional resistance in the axial direction, the cable is prevented from coming out.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows an embodiment, (A) is a front view, (B)
Is a side view and (C) is a vertical cross-sectional view of the bush. In the figure, 2 is a pedestal, 3 is a lower gripping material, 4 is a lower bushing, 5 is an upper gripping material, 6 is an upper bushing, 7 is a tightening bolt, and 9 is a cable. The cradle 2 receives the lower gripping material 3 and receives the lower gripping material 3
Receives the lower bush 4 and the bushes 4 and 6 are cables 9
And the upper holding member 5 is tightened with the tightening bolts 7 to hold the cable 9 via these members, and the pedestal 2 supports the cable 9.

The pedestal 2 is made of cast iron, for example, and is installed on a pedestal or the like (not shown). On the upper surface of the pedestal 2, a recess 2a is formed in the center so as to receive the lower gripping material 3, and ears 2b for tightening with the tightening bolts 7 are formed on both sides. The bushes 4 and 6 are made of an elastic material such as synthetic rubber, and have a semi-cylindrical shape that covers the cable 9, and the inner surfaces 4a and 6a contacting the cable 9 have a bellows shape, as shown in FIG. , Screw-shaped wavy irregularities are formed. Bush 4
The length of 6 and 6 is about 3 times the diameter of the cable 9. The gripping members 3 and 5 are made by pressing with a steel plate, for example, and have a semi-cylindrical shape so as to hold the bushes 4 and 6, and ear portions 3b and 5b are formed on both sides. Grasping materials 3 and 5
Has the same length as the bushes 4 and 6, and the bushes 4 and 6 are fitted into the gripping members 3 and 5, respectively, so as not to come off in the axial direction. The ears 5b and 3 of the gripping materials 5 and 3 are tightened through the tightening bolts 7.
A hole is formed in b, and a screw hole into which the tightening bolt 7 is screwed is cut in the ear 2b of the pedestal 2. It should be noted that there is a sufficient gap between the lower bushing 4 and the upper bushing 6 and between the lower gripping material 3 and the upper gripping material 5 so as not to hinder the tightening even when tightened with the tightening bolt 7. Need to be formed. In addition, 8 is a grounding screw.

Next, the operation will be described. The lower gripping material 3 and the lower gripping material 4 are placed on the pedestal 2, the cable 9 is placed thereon, and the upper bushing 6 and the upper gripping material 5 are placed on the lower gripping material 3 and the lower gripping material 3 so that The tightening bolt 7 is inserted through the holes of the ear portions 5b and 3b on both sides, and the tightening bolt 7 is screwed into the screw hole of the ear portion 2b of the pedestal 2 to tighten the upper gripping member 5 toward the pedestal 2. By the tightening of the tightening bolt 7, the bushes 4 and 6 are tightened and pressed against the cable 9. The bushes 4 and 6 are made of an elastic material such as synthetic rubber, and the inner surface thereof is formed with bellows-like or screw-like wavy unevenness as shown in (C). The recess 9 is elastically deformed and flexibly pressed against the cable 9. Therefore, even if the cable 9 expands and contracts, it is dealt with by the elastic deformation of the bushes 4 and 6,
The cable 9 is always grasped with almost the same grasping force. Further, since the wavy irregularities on the inner surfaces of the bushes 4 and 6 are irregular in the axial direction, a large frictional resistance is exerted on the movement of the cable 9 in the axial direction, and for example, the cable 9 is prevented from sliding down by its own weight. .

In the above embodiment, the bushes 4 and 6 are
Although the bellows-like unevenness is formed on the inner surface of the above, the unevenness may be formed only on one of the bushes 4 and 6 and the other may be uneven. Further, the length of the recess 2a of the pedestal 2 is set to be the same as the length of the lower bush 4 so that the lower bush 4 is directly received, so that the lower holding member 3 can be omitted. Further, the tightening bolt 7 may be a bolt / nut, and the screw hole of the ear 2b of the pedestal 2 may be a foolish hole so that the bolt / nut is used for tightening.

[0011]

As described above, according to the present invention, a pair of semi-cylindrical semi-cylindrical members, which are elastic bodies, are formed between the gripping member or the pedestal and the cable, and the bellows-like irregularities are formed on the inner surface contacting the cable. Since it is tightened with the bush interposed, even if the cable expands and contracts, the cable can be elastically gripped flexibly with almost the same grasping force, and the cable can be prevented from shifting due to unevenness. is there.
