Abstract
The utility model discloses a be applied to bracing piece in roof communication pole, this bracing piece include a plurality of sections metal poles and a ceramic rod, ceramic rod fixed connection between rather than adjacent metal pole. The ceramic rod lower extreme is equipped with a recess, is equipped with the screw hole on the recess both ends are horizontal, and the metal pole is placed in the recess, and the metal pole also is equipped with the screw hole on horizontal, and the screw hole that a bolt passed on recess and the metal pole carries out fixed connection. The last discoid arch of a plurality of that is equipped with of ceramic rod. The utility model discloses insulating nature based on ceramic rod to can avoid the thunderstorm weather problem of current bracing piece.
Description
Technical field
This utility model relates to communication pole research field in mobile communications network, particularly to a kind of support bar being applied in roof communication pole.
Background technology
According to the needs of the communication network development, on roof communication pole, the base station antenna feeder system of band support bar uses more and more universal, and its structure sees Fig. 1, and roof communication pole 5 uses several support bars 6 to be supported, and makes system more firm.But currently used support bar there is problems in that support bar is each made of a metal, metal itself has thunder effect of drawing, and the community owner's premise equipment therefore lived nearby in base station likely can be by broken by lightning.Real work occurs the problems referred to above the most really, causes base station to have to move, cause the huge waste of cost.Same, due to the thunder effect of drawing of metallic support rod, also the trouble free service of base station equipment is brought hidden danger.
Therefore it provides a kind of insulating support rod that can be applicable in roof communication pole has important using value.
Utility model content
The purpose of this utility model is to overcome the shortcoming of prior art with not enough, it is provided that a kind of support bar being applied in roof communication pole, and this support bar is insulating support rod, thus overcomes the lightning protection hidden danger that the nonisulated property of existing support bar brings.
The purpose of this utility model is realized by following technical scheme: a kind of support bar being applied in roof communication pole, including some sections of metallic rod and a ceramic bar, and fixing connection between the metallic rod that described ceramic bar is adjacent.This utility model insulating properties based on ceramic bar, thus can avoid existing support bar draw thunder problem.
Preferably, described ceramic bar top and bottom are equipped with a groove, and groove two ends are transversely provided with screwed hole, and metallic rod is placed in groove, and metallic rod also transversely is provided with screwed hole, and a bolt is fixedly connected through the screwed hole on groove and metallic rod.
Preferably, described metallic rod is hollow-core construction, the metallic rod socket that described ceramic bar is adjacent, such that it is able to reduce the cost of support bar, reduces its weight.
Preferably, described ceramic bar is provided with several discoid projections, thus the creep age distance required for providing for ceramic bar.
Preferred as one, described support bar includes the first metallic rod, the second metallic rod and ceramic bar, and described ceramic bar is arranged between the first metallic rod, the second metallic rod；The top of the second metallic rod is connected with communication pole, and the bottom of the first metallic rod is connected to ground.This structure is applied to the support bar in roof communication pole, can overcome the lightning protection hidden danger that the nonisulated property of existing support bar is brought.
Further, a length of 3～4 meters of described first metallic rod, a length of 3～4 meters of the second metallic rod, a length of 0.5～1 meter of ceramic bar.Still use existing method of attachment constant between second metallic rod and communication pole.Still use existing method of attachment constant between first metallic rod and ground.First metallic rod and the concrete length of the second metallic rod can be increased or decreased according to the height of roof communication pole.
This utility model compared with prior art, has the advantage that and beneficial effect:
This utility model insulating properties based on ceramic bar, common metal support bar is divided into some joints, it is connected fixing to ceramic bar and other metallic rod, invent the insulating support rod being applied in roof communication pole, this communication pole can be applicable to mobile communications network, it is especially adapted for use in lightning protection field, mobile base station, solves the lightning protection hidden danger brought due to the nonisulated property of existing support bar.

Fig. 3 is the structural representation of support bar described in the present embodiment.
Fig. 4 is the annexation figure of metallic rod and ceramic bar in the present embodiment.
In figure: 101 first metallic rod, 102 second metallic rod, 2 ceramic bars, 3 grooves, 4 bolts, 5 communication poles, 6 support bars.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, this utility model is described in further detail, but embodiment of the present utility model is not limited to this.
As shown in Figure 2,3, support bar described in the present embodiment is insulating support rod, being applied in roof communication pole, specifically include the first metallic rod the 101, second metallic rod 102 and ceramic bar 2, described ceramic bar 2 is arranged between first metallic rod the 101, second metallic rod 102.A length of 3～4 meters of described first metallic rod 101, a length of 3～4 meters of the second metallic rod 102, a length of 0.5 meter of ceramic bar 2.Still use existing method of attachment constant between second metallic rod and communication pole.Still use existing method of attachment constant between first metallic rod and ground.First metallic rod and the concrete length of the second metallic rod can be increased or decreased according to the height of roof communication pole.Same, support bar includes how many sections of metallic rod or ceramic bars, and this is also that those skilled in the art in actual applications can be as the case may be from main separation.
Seeing Fig. 3, metallic rod 101,102 described in the present embodiment is hollow-core construction, the metallic rod socket that described ceramic bar 2 is adjacent.Ceramic bar is made up of porcelain part.Porcelain part makes ceramic bar have good electrical insulation strength.In the present embodiment, one ceramic bar is set and has two aspect effects: one is to support securely and fixed communication bar, two is that ceramic bar has enough insulating properties and mechanical strength, erosion to chemical impurity has enough resist abilities, and adapts to the change of surrounding (such as temperature and humidity etc.).It addition, ceramic bar is provided with several discoid projections, such that it is able to the creep age distance required for providing for ceramic bar.
See Fig. 4, described ceramic bar 2 lower end and upper end are arranged with groove 3, and groove 3 two ends are transversely provided with screwed hole, and metallic rod is placed in groove, and metallic rod also transversely is provided with screwed hole, a bolt 4 is fixedly connected through the screwed hole on groove and metallic rod.
Above-described embodiment is this utility model preferably embodiment; but embodiment of the present utility model is also not restricted to the described embodiments; other any without departing from the change made under spirit of the present utility model and principle, modify, substitute, combine, simplify; all should be the substitute mode of equivalence, within being included in protection domain of the present utility model.
