A second through hole 402 is provided at a position corresponding to the second through hole 402, and a ring 102 made of sponge material is fixed at a position corresponding to the signal antenna 101 and the second through hole 402. When actually in use, the antenna body 1 is fixed in the installation box 2 through the fixing component 8, and the two sides of the installation box 2 are covered by the detachable mounting plate 4 and the box cover 7 respectively, and the multiple signal antennas 101 connected to the antenna body 1 are extended from the second through hole 402 and the first through hole 301, and the ring 102 is used to stabilize the signal antenna 101 and block the second through hole 402 to prevent dust from entering the installation box 2; and when used for a long time At the same time, since the gap cavity 6 is close to the meter box shell 3 and air can flow through the through hole 301, air can flow in the gap cavity 6 to improve the heat dissipation and cooling effect around the installation box 2. Moreover, when a large number of smart meters are overheated in the meter box, when the heat is diffused to the vicinity of the installation box 2, the gap cavity 6 through which the gas flows causes the heat to flow into the gap cavity 6 due to the temperature difference and be drawn out from the through hole 301 for heat exchange, thereby preventing the heat from always being diffused on the outer wall around the installation box 2, thereby preventing the installation box 2 from overheating and affecting the effective and accurate operation of the communication antenna.

Balls 19 are rolled on the outer and inner sides of the positioning tube 18. In actual use, the positioning tube 18 arranged around the outer periphery of the antenna body 1 cooperates with the rotatable ball 19, so that when the antenna body 1 fails in a certain area or the heat exchange is slow, the heat exchange of the positioning tube 18 with the meandering structure and the rolling state of the ball 19 with the air flow movement can quickly disperse the hot air flow and avoid heat accumulation, so as to improve the heat dissipation and cooling effect of the antenna body, thereby further ensuring the effective stability of the communication antenna for long-term work and signal transmission.

[0039] In the present invention, reference is made to Fig.10 A fixing groove distributed in a circular array is provided at a position corresponding to the outer wall of the fixed tube 13 and the rotating ring 15, a fixing box 14 is fixed in the fixing groove, one side of the fixing box 14 is connected to the fixed tube 13, and a through hole 141 is provided at the top and the bottom of the fixing box 14.
