In order to achieve the above purpose, the utility model adopts the following technical scheme:

designing an overhead cable spacer, which comprises two sub-spacers, wherein each sub-spacer comprises three first support rods arranged in a regular triangle manner, one end of each first support rod is integrally connected with a central plate, the other end of each first support rod is connected with a second support rod, one end of each second support rod, which is far away from the first support rod, is fixedly connected with a first fixing ring, a first opening is formed in the first fixing ring, a second fixing ring is arranged in the first fixing ring, one end, which is close to the first support rod, of the second fixing ring is fixedly connected with the inner wall of the first fixing ring, and the other side of the second fixing ring is provided with a second opening;

one side surface of the central plate is provided with a screw, the other side surface of the central plate is embedded with an internal threaded pipe, and the screw and the internal threaded pipe are concentric with the central plate;

the screw rod of one sub-spacer is in threaded connection with the internal threaded pipe of the other sub-spacer.

Preferably, a blind hole is formed in one end, far away from the central plate, of the first support rod, the second support rod is inserted into the blind hole, and a fixing screw is connected to the side wall of the blind hole in a threaded mode.

Preferably, the first support rod is provided with a through hole.

Preferably, the first opening and the second opening are not arranged in a coincident manner.

The utility model provides a pair of overhead cable conductor spacer, beneficial effect lies in: the utility model has the advantages of simple structure and convenient to use, two sub-conductor spacer both can use through threaded connection's mode is fit, also can use respectively after the split, comparatively nimble.

Drawings

Fig. 1 is a front view of an overhead cable spacer according to the present invention;

fig. 2 is a right side view of the overhead cable spacer according to the present invention.

In the figure: the support device comprises a first support rod 1, a second support rod 2, a central plate 3, a first fixing ring 4, a second fixing ring 5, a screw rod 6, an internal threaded pipe 7 and a through hole 8.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-2, an overhead cable spacer comprises two sub-spacers, each sub-spacer comprises three first support rods 1 arranged in a regular triangle manner, one end of each first support rod 1 is integrally connected with a central plate 3, the other end of each first support rod 1 is connected with a second support rod 2, one end, far away from the central plate 3, of each first support rod 1 is provided with a blind hole, each second support rod 2 is inserted into the blind hole, the side wall of each blind hole is in threaded connection with a fixing screw, and the overall length of the first support rods 1 and the second support rods 2 is convenient to adjust. The through hole 8 is formed in the first supporting rod 1, so that the overall weight of the sub-spacers can be reduced, and the using effect is better.

One end, far away from the first supporting rod 1, of the second supporting rod 2 is fixedly connected with a first fixing ring 4, a first opening is formed in the first fixing ring 4, a second fixing ring 5 is arranged in the first fixing ring 4, one end, close to the first supporting rod 1, of the second fixing ring 5 is fixedly connected with the inner wall of the first fixing ring 4, and a second opening is formed in the other side of the second fixing ring 5. The first fixing ring 4 and the second fixing ring 5 are used for fixing cables, and when the cable fixing device is used, the first fixing ring 4 and the second fixing ring 5 can be broken off, and the cables are clamped into the second fixing ring 5 from the first opening and the second opening in sequence. The first opening and the second opening are not overlapped, so that the anti-falling effect is good. In practical use, the first fixing ring 4 and the second fixing ring 5 are preferably made of an insulating plastic ring having good elasticity and toughness, such as PC, and the like, and are arranged so as to be easily separated from the first fixing ring 4 and the second fixing ring 5.

A screw 6 is installed on one side face of the central plate 3, an internal threaded pipe 7 is embedded in the other side face of the central plate 3, and the screw 6 and the internal threaded pipe 7 are arranged concentrically with the central plate 3.

The screw 6 of one of them sub-conductor spacer and the 7 threaded connection of internal thread pipe of another sub-conductor spacer, two sub-conductor spacers both can use through the mode fit of threaded connection, also can separate the use after the split, and is comparatively nimble, the use of the practicality of being convenient for.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
