Description

Technical Field

[0001] The utility model relates to the technical field of antenna structures, in particular to an external antenna installation structure. Background Art

[0002] In recent years, ultrasonic water meters or electromagnetic water meters have appeared more and more in the field of water metering, gradually replacing mechanical meters and being widely used; and the installation and use environment of water meters has become more and more complicated. The structure of the built-in antenna is limited by the internal installation environment of the equipment and the poor signal strength. It is difficult to meet the strength requirements of the remote transmission signal. In contrast, the signal strength of the external antenna is stronger and more stable, and can better adapt to different environments. Therefore, large instruments or equipment with complex installation environments and high signal strength requirements often use external antennas. An external antenna is a transducer installed on the outer surface of the equipment or on the wall, which transmits information through electromagnetic waves. However, most devices on the market have external antennas such as Figure 1 As shown, the antenna 01 is usually installed on the outer wall of the device or wall 03 using a magnet 02 or double-sided tape. Long-term exposure to the external environment will reduce the magnetic force or viscosity, resulting in unstable installation and short service life, and frequent replacement is required. In an installation environment where magnetic attraction cannot be achieved, additional fixing devices are usually required for fixing, which is inconvenient to disassemble and move, and has poor portability. In addition, most of the existing antennas have no protection and are directly exposed to the outside, with poor sealing and waterproof properties, and are easily corroded by the external environment or damaged by humans, affecting their service life.
