[0002] Helical antennas are a common type of antenna, widely used in communications, radar, and other fields. However, existing helical antennas often suffer from inconvenient maintenance during use.

[0003] In the prior art, such as the "spiral antenna" with patent application number CN200620068893.4, the antenna includes a first spiral vibrator that determines a first operating frequency, a linear vibrator that determines a second operating frequency, a second spiral vibrator that determines a third operating frequency, and a straight section connecting the first spiral vibrator and the second spiral vibrator. The first spiral vibrator and the second spiral vibrator are connected at one end by the straight section. The axis of the first spiral vibrator and the axis of the second spiral vibrator are coaxial, and the straight section connecting the axis of the first spiral vibrator and the second spiral vibrator is also coaxial with the axis. The linear vibrator is coaxial, and the inner core wire of the feed point near one end of the linear vibrator is electrically connected to the end of the first spiral vibrator away from the second spiral vibrator. The linear vibrator passes through the first spiral vibrator along the axis of the first spiral vibrator, and the axial length of the first spiral vibrator is greater than the length of the linear vibrator.

[0004] However, existing helical antennas require a protective shell, and the shells protecting the antenna need to be connected and fixed with bolts. This type of fixing method requires tools to disassemble when the helical antenna needs to be maintained, which increases the difficulty of disassembly and causes inconvenience. Utility Model Content

[0005] The purpose of this invention is to solve the problem that in the prior art, spiral antennas require a protective shell, and the protective shells need to be connected and fixed with bolts. This type of fixing method requires tools to disassemble when the spiral antenna needs to be maintained, which increases the difficulty of disassembly and causes inconvenience. Therefore, this invention proposes a spiral antenna that is easy to maintain.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a helical antenna that is easy to maintain, comprising an antenna mechanism, a protective mechanism provided on the outer side of the antenna mechanism, and an installation mechanism provided in the middle of the antenna mechanism. The antenna mechanism includes a mounting base, and a mounting frame is provided on the top of the mounting base. The mounting frame is mounted on the helical antenna. The protective mechanism includes a long sheath and a short sheath. The long sheath is provided on the top of the mounting base, and the short sheath is provided on the bottom of the mounting base. The installation mechanism includes multiple connecting seats. Limit fasteners are movably installed at both ends of the connecting seats. Clamping members are symmetrically and movably installed on the sides of the connecting seats. A fastening ring is provided through the inner side of the clamping member, and a clamping block is provided at one end of the clamping member.

[0007] Preferably, one end of both the long sheath and the short sheath is provided with an outer sealing ring, and an outer sealing rubber ring is provided on the inner side of the outer sealing ring.

[0008] Preferably, the long sheath and the short sheath are provided with an inner sealing ring, and the outer wall of the inner sealing ring is provided with an inner sealing rubber ring.

[0009] Preferably, a rotating seat is symmetrically and movably mounted on the side of the connecting seat, and the clamping member is connected to the rotating seat.

[0010] Preferably, a narrow protrusion and a limiting protrusion are fixedly installed on the inner side of the clamping member, and the fastening ring is clamped between the narrow protrusion and the limiting protrusion.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, the symmetrically distributed limiting fasteners on the connecting seat can be fastened into the fastening slots opened on the long and short protective sleeves respectively. By pushing the fastening ring outward, the fastening ring is locked between the narrow protrusion and the limiting protrusion, thereby driving the pressing block at one end of the pressing member to press the limiting fastener. This facilitates quick installation and fastening, and also makes it easy to push the fastening ring towards the center during later maintenance, so that the pressing member is released from its pressing state, thus facilitating quick disassembly and improving the convenience of maintenance.

[0014] 2. In this utility model, an outer sealing ring is connected to the long and short sheaths, and an outer sealing rubber ring is used to seal the connection to the outer walls of the long and short sheaths. Furthermore, the long and short sheaths are also provided with inner sealing rings embedded in the inner side of the connection. The inner sealing rubber ring on the inner sealing ring further seals the connection with the connection, thereby improving the sealing performance of the connection and preventing moisture from entering and affecting the normal use of the antenna in complex environments, effectively extending the service life of the antenna.
