Abstract
Description
Technical Field
[0001] This application relates to the field of wireless communication technology, and in particular to a corrosion-resistant rubber rod antenna. Background Technology
[0002] Wireless communication is a communication method that utilizes the property of electromagnetic waves to propagate in free space for information exchange. In recent years, wireless communication technology has been the fastest-growing and most widely used technology in the field of information and communication. Wireless communication implemented while in motion is also commonly referred to as mobile communication, and the two are collectively known as wireless mobile communication.
[0003] An antenna is a transducer that converts guided waves propagating on a transmission line into electromagnetic waves propagating in an unbounded medium, or vice versa. Antennas are generally reversible. They are components in wireless equipment used to transmit or receive electromagnetic waves. Engineering systems such as radio communication, broadcasting, television, radar, navigation, electronic countermeasures, remote sensing, and radio astronomy all rely on antennas to transmit information using electromagnetic waves. Furthermore, antennas are also needed for transmitting energy, not just signal energy radiation. Antennas are broadly classified into two types: internal and external. Common internal antennas include monopole antennas, PIFA antennas, patch ceramic antennas, and FPC antennas; common external antennas include rod antennas, telescopic antennas, helical antennas, and vehicle-mounted antennas.
[0004] Regarding the aforementioned related technologies, the inventors have discovered the following deficiencies: the existing technology lacks a protective mechanism structure, and the antenna connector is usually exposed to the air. Oxygen and moisture in the air, industrial pollutants, and dust impurities can all cause varying degrees of corrosion to the antenna connector. In order to solve the deficiency of the lack of a protective mechanism in the existing technology, this application uses components such as a dust cover and a support rod, which enable the dust cover to drive the support rod to rotate, thereby allowing the sacrificial block to contact the connector. By utilizing the electrochemical principle of the sacrificial anode, the sacrificial block can be preferentially corroded before the connector, thus achieving the anti-corrosion effect on the connector. Utility Model Content

[0006] This application provides a corrosion-resistant glue rod antenna, which adopts the following technical solution: A corrosion-resistant glue rod antenna includes an antenna body, a connector installed at the bottom end of the antenna body, a dust cover fitted onto the outer surface of the antenna body, a positioning ring fixedly connected to the outer surface of the antenna body, the positioning ring being located below the dust cover, three support rods arranged at equal angles rotatably connected to the outer surface of the positioning ring, each support rod being rotatably connected to a drive bar, a slot being provided at the bottom end of each support rod, and a sacrificial block being inserted into the bottom end of each support rod through the slot.
[0007] Optionally, the bottom of the dust cover is provided with an annular groove, and a sealing ring is fixedly connected inside the annular groove.
[0008] Optionally, a drive ring is slidably connected to the outer surface of the antenna body, and a top groove is formed on the lower surface of the drive ring.
[0009] Optionally, a bottom ring is fixedly connected to the outer surface of the antenna body, and a bottom groove is formed on the upper surface of the bottom ring.

[0012] Optionally, a spring is provided below the drive ring, and the top end of the spring contacts the inner wall of the top groove.
[0013] In summary, this application includes the following beneficial technical effects:
[0014] 1. This utility model, by providing components such as a dust cover and a support rod, enables the dust cover to drive the support rod to rotate, allowing the support rod to rotate and cause the sacrificial block to come into contact with the outer surface of the joint. This allows the sacrificial block to corrode preferentially over the joint, thereby preventing corrosion of the joint. Thus, this utility model achieves the effect of protecting the joint by providing components such as a support rod and a drive bar.
[0015] 2. This utility model, by incorporating components such as a fixing ring and a sealing ring, achieves its effect of reducing the contact between the joint and external air through the cooperation between the fixing ring and the sealing ring. This is achieved by using a dust cover to bring the sealing ring into close contact with the outer surface of the installation equipment. Attached Figure Description

[0023] The following is in conjunction with the appendix Figure 1-6 The figure provides a further detailed description of this application.
[0024] This application discloses a corrosion-resistant rubber rod antenna. For example... Figure 1 , 2As shown in Figures 3 and 4, a corrosion-resistant rubber rod antenna includes an antenna body 1 made of silicone. The outer surface of the antenna body 1 is coated with a titanium dioxide coating to improve its UV resistance. A connector 2, an SMA male connector made of nickel-plated brass, is installed at the bottom of the antenna body 1. A cavity is formed inside the antenna body 1, and the radiator inside the cavity is electrically connected to the connector 2 via a wire. A dust cover 3, made of thermoplastic polyurethane, is fitted onto the outer surface of the antenna body 1. The dust cover 3 is coated with a benzotriazole coating to improve its sun protection effect. The dust cover 3 is used to shield and protect the connector 2. A positioning ring 4 is fixedly connected to the outer surface, located below the dust cover 3. Three support rods 5 arranged at equal angles are rotatably connected to the outer surface of the positioning ring 4. Each support rod 5 is rotatably connected to a drive bar 6. The positioning ring 4, support rods 5 and drive bar 6 are all made of polyethylene. A slot 7 is opened at the bottom end of each support rod 5. A sacrificial block 8 is inserted into the bottom end of each support rod 5 through the slot 7. The sacrificial block 8 is made of zinc alloy. The sacrificial block 8 can be installed and removed through the slot 7, which facilitates replacement. The support rod 5 can rotate to drive the sacrificial block 8 to contact the outer surface of the connector 2, so that the sacrificial block 8 can preferentially undergo corrosion reaction with the connector 2, thereby achieving electrochemical protection for the connector 2.
[0025] Please see Figure 1 , 2 3. A fixing ring 16 is rotatably connected to the top of the dust cover 3. The fixing ring 16 is made of thermoplastic polyurethane and its outer surface is coated with benzotriazole. The inner wall of the fixing ring 16 is threaded to the outer surface of the antenna body 1. The fixing ring 16 can drive the dust cover 3 to move along the axial direction of the antenna body 1, thereby protecting the connector 2.
[0026] Please see Figure 1 , 2 3, 6. The bottom of the dust cover 3 is provided with an annular groove 9. A sealing ring 10 is fixedly connected inside the annular groove 9. The sealing ring 10 is made of silicone. The dust cover 3 can drive the sealing ring 10 to fit tightly against the outer surface of the installed equipment. The annular groove 9 and the sealing ring 10 can be installed in a multi-level concentric circle manner, thereby further improving the sealing effect of the dust cover 3.
[0027] Please see Figure 2 , 3 A drive ring 11 is slidably connected to the outer surface of the antenna body 1. The drive ring 11 is made of polyethylene. The other end of each drive bar 6 is rotatably connected to the outer surface of the drive ring 11. A top groove 12 is provided on the lower surface of the drive ring 11. The drive ring 11 can drive the support rod 5 to reverse through the drive bar 6, thereby causing the sacrificial block 8 to disengage from the connector 2.
[0028] Please see Figure 2 , 3 5. A limiting ring 15 is provided below the positioning ring 4. The limiting ring 15 is made of polyethylene. The limiting ring 15 is fixedly connected to the outer surface of the antenna body 1. The lower surface of the limiting ring 15 is in contact with the upper surface of the driving ring 11. The limiting ring 15 is fixedly connected to the outer surface of the antenna body 1. The limiting ring 15 limits the movement of the driving ring 11.
[0029] Please see Figure 2 , 3 5. A spring 17 is provided below the drive ring 11. The spring 17 is sleeved on the outer surface of the antenna body 1. The top of the spring 17 is in contact with the inner wall of the top groove 12. The spring 17 is used to push the drive ring 11 to reset. When the dust cover 3 moves towards the connector 2, the dust cover 3 drives the support rod 5 to rotate. The support rod 5 drives the drive ring 11 to slide through the drive bar 6. The spring 17 is compressed. When the dust cover 3 moves towards the connector 2, the spring 17 pushes the drive ring 11 to reset. The drive ring 11 pushes the support rod 5 to reverse through the drive bar 6.
[0030] Please see Figure 2 , 3 5. A bottom ring 13 is fixedly connected to the outer surface of the antenna body 1. A bottom groove 14 is opened on the upper surface of the bottom ring 13. The bottom groove 14 corresponds to the top groove 12. The bottom end of the spring 17 contacts the inner bottom wall of the bottom groove 14. The bottom ring 13 supports the spring 17 through the bottom groove 14.
[0031] The implementation principle of the corrosion-resistant rubber rod antenna in this application embodiment is as follows: The antenna body 1 is connected to the corresponding interface of the device through the connector 2. The fixing ring 16 is rotated, and the fixing ring 16 moves towards the connector 2 while rotating. The fixing ring 16 drives the dust cover 3 and the sealing ring 10 to move, so that the sealing ring 10 is in close contact with the outer surface of the device, thereby achieving sealing protection for the connector 2. At the same time, the dust cover 3 drives the support rod 5 to rotate. The support rod 5 drives the drive ring 11 to slide towards the bottom ring 13 through the drive bar 6. The spring 17 is compressed, and the support rod 5 drives the sacrificial block 8 to contact the outer surface of the connector 2. The fixing ring 16 is reversed, and the fixing ring 16 drives the dust cover 3 and other components to move in the opposite direction. The dust cover 3 releases the limit on the support rod 5. The spring 17 pushes the drive ring 11 to reset. The drive ring 11 pushes the support rod 5 to reverse through the drive bar 6, so that the sacrificial block 8 is disengaged from the connector 2.
[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
