Description

Technical Field

[0001] The utility model relates to a feed support rod for an antenna and an antenna, and is applicable to the technical field of antenna manufacturing. Background Art

[0002] An antenna is a device that receives, converts, and transmits signals. It can convert guided waves received from a signal transmission line into electromagnetic waves that can propagate in space and send them out, or perform the opposite reception, conversion, and transmission. It is widely used in various signal transmission scenarios. The antenna feed support rod is a component used on the antenna. Its function is to fix the feed and high-frequency head in the antenna at the focus of the antenna's reflective surface (such as the attached Figures 4-6 ), so that the antenna can receive and transmit signals. In the prior art, in order to reduce the weight of antenna parts and facilitate assembly on the one hand, and to reduce production costs and processing difficulty and facilitate bending on the other hand, the feed pole is usually made of a hollow metal tube. However, since most antennas need to be installed in outdoor scenes, when encountering windy and rainy weather, a large amount of rainwater will enter the interior of the pole from the pole port and accumulate at the bend, which can easily cause the feed pole to rust and corrode, affecting the service life of the antenna. And because the antenna reflective surface needs to be adjusted and maintained at a suitable angle during use, the rainwater accumulated inside the feed pole will increase the weight of the pole, thereby causing the deflection angle of the antenna reflective surface to shift, affecting the normal use of the antenna. Utility Model Content

[0003] In order to solve the defects of the above-mentioned prior art, the present invention proposes a feed support rod for an antenna and an antenna.

[0004] On the one hand, the utility model discloses a feed support rod for an antenna, which is used to fix the feed source on one side of the concave surface of the antenna reflecting surface, including a first rod body with one end fixedly connected to the convex surface of the antenna reflecting surface, a second rod body with one end connected to the feed source, and a bent pipe portion connected to the other end of the first rod body and the other end of the second rod body respectively, the inner side surface of the bent pipe portion is set to a concave surface, and the inner side surface of the bent pipe portion is provided with at least three leakage holes that pass through the bent pipe portion, and the at least three leakage holes are arranged along the arc length of the bent pipe portion. By opening at least three drainage holes in the bent pipe part of the feed strut, on the one hand, rainwater entering the feed strut can be quickly discharged, and at least three drainage holes also allow the antenna reflector to drain quickly when adjusted to any pitch angle, completely avoiding water accumulation at the bent pipe, which not only prevents rust inside the feed strut, but also prevents excessive water accumulation inside the strut from causing the pitch angle of the antenna reflector to deflect, thereby avoiding affecting the normal operation of the antenna; on the other hand, at least three drainage holes also improve the ventilation effect inside the feed strut, accelerate the air flow inside the strut, and allow the water stains remaining inside the feed strut to evaporate quickly, avoiding rust and corrosion inside the feed strut, and increasing the service life of the feed strut.

[0005] Furthermore, at least three water leakage holes are respectively located at 1 / 4±0.2, 1 / 2±0.2, and 3 / 4±0.2 of the curved pipe portion. By evenly distributing at least three water leakage holes around 1 / 4, 1 / 2, and 3 / 4 of the curved pipe portion, the antenna reflecting surface can drain water smoothly through the water leakage holes at different adjustment angles, further avoiding water accumulation.

[0006] Furthermore, the feed support rod also includes a mounting assembly connected to one end of the second rod and used to clamp the feed. The mounting assembly includes a sleeve with one end sleeved over one end of the second rod, a first clamping member fixed to the other end of the sleeve, and a second clamping member detachably connected to the first clamping member. One end of the sleeve is detachably connected to one end of the second rod via a bolt. The feed is clamped between the first and second clamping members, and then fixed to one end of the second rod via the sleeve, facilitating the feed support rod to perform its function.

[0007] Furthermore, the first clamp and the second clamp are both configured in a semi-annular shape, and the first clamp and the second clamp constitute a complete circular ring for clamping the feed source. The first clamp and the second clamp are detachably linked by bolts, and the first clamp and the second clamp, both of which are semi-annular, constitute a space for clamping the feed source, thereby achieving clamping and fixing of the feed source. Moreover, the bolts can not only realize the connection between the first clamp and the second clamp, but also adjust the tightness of the connection between the first clamp and the second clamp, thereby facilitating the clamping of feed sources of different models and sizes.

[0008] Furthermore, the water leakage holes are formed by punching with a punch press, which not only avoids the burrs easily generated by traditional drilling processing, but also improves processing efficiency and reduces the difficulty of the processing personnel.

[0009] Furthermore, the first rod body, the second rod body and the bent tube portion are all configured as hollow square tubes, which on the one hand can reduce material usage, save costs, reduce the difficulty of bending processing, and improve processing efficiency; on the other hand, it also reduces the weight of the antenna, making it easier to carry and install; in addition, the hollow square tube also facilitates the assembly of the feed support rod and other components in the antenna, such as the back clip, thereby improving assembly stability.

[0010] Furthermore, the first rod body, the second rod body and the bent tube portion are integrally formed, thereby improving the structural strength of the feed support rod and thereby increasing its service life.

[0011] Furthermore, the angle between the first rod and the second rod is less than 90°, which facilitates fixing the feed source at the focus of the antenna reflection surface.

[0012] In another aspect, the utility model discloses an antenna, including antenna reflector, one end with the convex surface of antenna reflector connects the feed support pole, the base fixed on the ground, two ends respectively with the convex surface of antenna reflector and the base connects the stand, this feed support pole has used above-mentioned for antenna's feed support pole.

[0013] Due to the above technical scheme application, the utility model has the following advantages compared with prior art:
