Abstract
The utility model relates to a special radome for an alarm, belonging to the technical field of alarm accessory, which comprises an antenna on the alarm. The utility model adopts the technical proposals that a quadrate hollow radome is arranged on an external side of the alarm and the antenna is covered in the radome, at least a hollow fixed column is positioned vertically in the radome. After the modification on the prior art, the special radome can be added on the alarm for tightly sealing the antenna, so that, the communication antenna can be protected from being damaged by human beings and eroded less by environment effectively.
Description
Technical field
The utility model belongs to the alarm field of accessories, specifically is a kind of alarm dedicated antenna cover.
Background technology
GSN (GPRS) power transformer, anti-theft alarm for electric power cable, because of it is installed in an outdoor open-air platform mostly, require waterproof, antirust, so producer generally adopts aluminum alloy casing, GSN (GPRS) just must expose in outside like this, exposing to the weather drenches with rain, and has both influenced its life-span, is subject to destruction again.
The utility model content
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, the existing product technology is improved, provide a kind of communication reception antenna that promptly can prevent by artificial destruction, can effectively reduce the alarm dedicated antenna cover that communication antenna is subjected to environmental attack simultaneously again.
For achieving the above object, this practical novel being achieved through the following technical solutions:
It is a kind of alarm dedicated antenna cover, comprise the antenna that is arranged on the alarm, the present technique main points are that the external side of alarm is provided with the antenna cover body of square hollow, and antenna is covered by in the antenna cover body, is vertically arranged with the fixed leg of at least 1 hollow in this antenna cover body.
In order to ensure combination closely after both installations, a wherein side of antenna cover body openend is processed with locating groove.
In addition, for the ease of the installation of antenna cover body, the height of fixed leg is less than the height of antenna cover body.
After the utility model carries out above-mentioned improvement to prior art, because for alarm has installed special-purpose antenna cover body additional, with tight the sealing of antenna, therefore have and promptly can prevent communication antenna by artificial destruction, can effectively reduce the advantage that communication antenna is subjected to environmental attack again simultaneously.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1: the utility model embodiment 1 structural representation.
The A of Fig. 2: Fig. 1 is to structural representation.
Embodiment
As shown in Figure 1, this alarm dedicated antenna cover, comprise the antenna that is arranged on the alarm, the present technique main points are that the external side of alarm is provided with the antenna cover body 1 of square hollow, antenna is covered by in the antenna cover body 1, be vertically arranged with the fixed leg 3 of at least 1 hollow in this antenna cover body 1, the cavity of fixed leg 3 hollows is fastening screw 4.
In order to ensure combination closely after both installations, as shown in Figure 2, a wherein side of antenna cover body 1 openend is processed with locating groove 2.
In addition, for the ease of the installation of antenna cover body, the height of fixed leg is less than the height of antenna cover body.
After the utility model carries out above-mentioned improvement to prior art, because for alarm has installed special-purpose antenna cover body additional, with antenna Tight seals, and therefore has namely can prevent communication antenna by artificial destruction, can effectively reduce communication antenna again simultaneously Be subjected to the advantage of environmental attack.
