Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of the antenna feeder joints water-tight device that the utility model provides.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.
Referring to Fig. 1, is the structural representation of the antenna feeder joints water-tight device that the utility model provides.
Described antenna feeder joints water-tight device 1 comprises the first housing 11, second housing 12, pivot 13 and plate 14.
Described first housing 11 comprises antenna feeder chamber 111, moisture absorption groove 112, moisture absorption medium 113, seal groove 114, sealing medium 115 and the first enclosure body 116.Described antenna feeder chamber 111 is located in the middle part of described first enclosure body 116, and described moisture absorption groove 112 and described seal groove 114 are located at the outside in described antenna feeder chamber 111 successively.Described moisture absorption medium 113 is filled in described moisture absorption groove 112, and described sealing medium 115 is filled in described seal groove 114.
The structure of described second housing 12 is consistent with described first housing 11.
Described first housing 11 is symmetrical arranged with described second housing 12, described first housing 11 side is articulated in described second housing 12 by described pivot 13, described plate 14 is arranged independent of described first housing 11 and described second housing 12, concrete when implementing with the use of.
During concrete enforcement, antenna feeder joints is placed in described antenna feeder chamber 111 place of described first housing 11, described second housing 12 is turned to along described pivot 13 and overlaps with described first housing 11, and described plate 14 is inserted described first housing 11 and described second housing 12 relative to the opposite side of described pivot 13, make described first housing 11 be fixed on described second housing 12.
