Description

Technical Field

[0001] The utility model relates to the technical field of antennas, in particular to a novel low-frequency antenna device. Background Art

[0002] A low-frequency antenna is an antenna used to receive or send low-frequency signals. Low-frequency signals usually refer to radio signals with lower frequencies, generally ranging from a few kHz to several hundred MHz. Low-frequency antennas are widely used in the fields of communications, broadcasting, navigation, and remote control. In practical applications, there are many types of low-frequency antennas, including rod antennas, coil antennas, and shortwave antennas. It is very important to choose a suitable low-frequency antenna according to specific usage scenarios and needs.

[0003] At present, traditional low-frequency antennas have a fixed structure and cannot be adjusted during installation for complex installation environments and different equipment, which leads to installation problems. In addition, their components are single and their resonant frequency is difficult to adjust during use. Antennas of different specifications are required, which increases the manufacturing cost and cannot meet people's needs. Therefore, a new low-frequency antenna device is needed. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides a novel low-frequency antenna device, which solves the problems raised in the above background technology.

[0005] To achieve the above objectives, the utility model is implemented through the following technical solutions: a new low-frequency antenna device, including an antenna, a coil is provided at the middle end of the antenna, a capacitor is provided inside the coil, both ends of the capacitor are connected to the two ends of the coil through a capture assembly, a telescopic sleeve is sleeved on the top end of the antenna, a connecting line is provided at the bottom end of the antenna, an adjustment shaft is provided on the surface of the antenna, the bottom of the adjustment shaft is rotatably connected to a mounting seat through a rotating shaft, and a magnetic suction block is provided at the bottom of the mounting seat.

[0006] Optionally, a surface of the capacitor is sleeved with a thermoplastic soft sleeve for protecting the capacitor.

[0007] Optionally, a protective soft cover is provided at the connection between the antenna and the connecting line.

[0008] Optionally, the connection points between the two ends of the coil and the antenna are located on the same horizontal line of the center of the coil.

[0009] Optionally, a removable micro suction cup is inserted into the lower surface of the mounting seat.

[0010] Optionally, a scale is provided on the surface of one end of the antenna sleeve connected to the telescopic sleeve rod.

[0011] The utility model provides a novel low-frequency antenna device, which has the following beneficial effects:

[0012] 1. The novel low-frequency antenna device protects the connection ends of the capacitor and the connecting wire with the antenna by setting a thermoplastic soft cover and a protective soft cover. By setting a telescopic sleeve rod, the effective length of the antenna can be changed by telescopic length, thereby adjusting the resonant frequency of the antenna to adapt to receiving or sending signals of different frequencies, thereby improving the flexibility of the antenna and adapting to devices with different resonant frequency requirements, effectively reducing its manufacturing cost, and by setting the scale, the operator can achieve precise adjustment.

[0013] 2. The new low-frequency antenna device can be installed by magnetic attraction or suction cup adsorption through the setting of magnetic blocks and micro suction cups, which is convenient for the installation of the antenna and can adapt to different installation equipment. By adjusting the setting of the axis and the rotating shaft, the antenna can be adjusted according to the actual situation. The angle and orientation of the antenna can adapt to a more complex installation environment. BRIEF DESCRIPTION OF THE DRAWINGS
