Description

Technical Field

[0001] The utility model relates to the technical field of antennas, in particular to an anti-interference antenna device. Background Art

[0002] Common household antennas in the prior art are often used to receive or send signals, and their range can cover the entire house. At the same time, the antenna also needs to have anti-interference characteristics to prevent certain factors from affecting the normal reception or transmission of the antenna.

[0003] However, the existing anti-interference measures or anti-interference structures are relatively complex and not easy to use, especially lacking anti-interference measures for home antennas.

[0004] For example, an anti-interference antenna device disclosed in Chinese patent CN217589426U uses a knob and a push block to control whether the anti-interference umbrella is closed or unfolded. When the anti-interference umbrella is in the open state, the signal strength of the main antenna body can be improved through the antenna extension line. This method is achieved by extending the antenna itself and unfolding it. At the same time, the anti-interference film on the other side can resist interference from interference sources in a specific direction. If the anti-interference umbrella is closed as a whole, the entire main antenna body is relatively wrapped around, thereby enhancing the all-round anti-interference characteristics of the antenna. This structure is simple to operate and use, simple to store, does not take up too much space, and does not increase too much weight, and is suitable for home use.

[0005] However, the lower end of the anti-interference antenna device is not provided with a mounting structure, so it is not convenient to disassemble and assemble the antenna.

[0006] For this reason, we urgently need to provide an anti-interference antenna device that is easy to disassemble and assemble. Utility Model Content

[0007] The utility model aims to provide an anti-interference antenna device to solve the problem that the lower end of the anti-interference antenna device proposed in the above background technology is not provided with a mounting structure, thereby making it inconvenient to disassemble and assemble the antenna.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-interference antenna device, comprising a base plate and an antenna, wherein the antenna is fixedly connected to the middle position of the upper side of the base plate, and an anti-interference mechanism is connected to the outer ends of the base plate and the antenna, wherein the anti-interference mechanism comprises an installation unit and an anti-interference unit, wherein the installation unit is arranged at the outer end of the base plate, and the anti-interference unit is arranged at the outer end of the antenna.

[0009] The mounting unit includes a mounting plate, a first threaded rod, a cylinder and a protective box. The mounting plate is fixed to the ground where the antenna is installed. The first threaded rod is fixedly connected to the four corners of the upper side of the mounting plate. The cylinder is connected to the outer side of the first threaded rod. The protective box is connected to the upper side of the mounting plate.

[0010] A further improvement is that mounting holes are provided at the four corners of the bottom plate, and the outer side of the first threaded rod is slidably connected to the inner side of the mounting hole. Thus, when the bottom plate is placed on the mounting plate, the first threaded rod will pass through the mounting hole inside the bottom plate, thus limiting the movement of the bottom plate during assembly and disassembly.

[0011] A further improvement is that the inner side of the cylinder is provided with an internal thread, the outer side of the first threaded rod is threadedly connected to the inner side of the cylinder, and the lower end of the cylinder is in contact with the four corners of the upper side of the bottom plate. Thus, after the bottom plate is placed on the mounting plate and the first threaded rod passes through the mounting hole, the cylinder is threadedly connected to the outer side of the first threaded rod until the lower side of the cylinder contacts the upper side of the bottom plate, so that the bottom plate can be fixed to the upper end of the mounting plate, thereby fixing the antenna to the middle position of the upper side of the bottom plate.

[0012] A further improvement is that a sliding hole is opened in the middle of the protection box, the outer side of the antenna is slidably connected to the inner side of the sliding hole, and the inner side of the protection box is slidably connected to the outer side of the bottom plate. Therefore, after the bottom plate is fixed to the mounting plate, the protection box on the outer side of the antenna is slid to the outer end of the bottom plate, so that the first threaded rod and the cylinder can be protected.

[0013] A further improvement is that the mounting plate and the protection box are made of stainless steel, so that the mounting plate and the protection box exposed to the air can be prevented from rusting while ensuring that the mounting plate and the protection box are sufficiently strong.

[0014] A further improvement is that the anti-interference unit includes a fixing ring, a second threaded rod, a rotating handle, a bolt, a curved plate and an anti-interference layer, the fixing ring is slidably connected to the outside of the antenna, the second threaded rod is connected to the middle position of the internal front end of the fixing ring, the rotating handle is fixedly connected to the front end of the second threaded rod, the bolt is connected to the left and right ends of the inside of the fixing ring, the curved plate is connected to the upper end of the fixing ring, and the anti-interference layer is fixedly connected to the upper side of the curved plate.

[0015] A further improvement is that a threaded hole is provided in the middle of the front end of the fixing ring, and the outer side of the second threaded rod is threadedly connected to the inner side of the threaded hole, so that when the rotating handle is turned to drive the second threaded rod in the threaded hole to rotate, the second threaded rod can move relative to the fixing ring.

[0016] A further improvement is that the rear end of the second threaded rod abuts against the front end of the outer side of the antenna, so that after the fixing ring is slid to the desired position outside the antenna, the rotating handle is turned to drive the second threaded rod to rotate in the threaded hole and move backward until the second threaded rod moves backward to contact the outer side of the antenna, so that the fixing ring can be fixed to the outer end of the antenna.

[0017] A further improvement is that the inner side of the arc plate is slidably connected to the outer side of the antenna, a threaded groove is provided at the middle position of one end of the arc plate at the lower part near the antenna, a round hole is provided at the middle position of the left and right ends of the fixing ring, the upper end of the outer side of the bolt is threadedly connected to the inner side of the threaded groove, and the outer side of the bolt is slidably connected to the inner side of the round hole. Thus, after placing the arc plate below the anti-interference layer on the left and right ends of the upper side of the fixing ring, and then passing the bolts through the round holes at the left and right ends of the fixing ring and then threading them into the threaded groove below the arc plate, the arc plate can be fixed to the left and right ends above the fixing ring, and the anti-interference layer can be fixed to the top of the fixing ring.

[0018] A further improvement is that a rubber pad is fixedly connected to the adjacent side of the two anti-interference layers above the fixing ring, and the anti-interference layer is made of an anti-interference umbrella, an anti-interference film and a protective rubber layer. Therefore, when the two anti-interference layers are fixed to the top of the fixing ring, the rubber pads on the adjacent sides of the two anti-interference layers are in contact, so that the two anti-interference layers can be sealed to prevent excessive dust from entering the anti-interference layers and affecting the operation of the antenna.

[0019] In summary, the present application discloses an anti-interference antenna device.

[0020] According to the technical solution, after the base plate is placed on the mounting plate and the first threaded rod passes through the mounting hole, the cylinder is threadedly connected to the outer side of the first threaded rod until the lower side of the cylinder contacts the upper side of the base plate. This allows the base plate to be fixed to the upper end of the mounting plate, thereby fixing the antenna to the middle position of the upper side of the base plate, and also makes it very convenient to disassemble and assemble the antenna.

[0021] Furthermore, after placing the arc plate under the anti-interference layer on the left and right ends of the upper side of the fixing ring, and then passing the bolts through the circular holes on the left and right ends inside the fixing ring and then threadedly connected to the threaded groove under the arc plate, the arc plate can be fixed to the left and right ends above the fixing ring, and at the same time the anti-interference layer is fixed to the top of the fixing ring, which plays an anti-interference role for the antenna in the anti-interference layer.

[0032] The mounting unit includes a mounting plate 301, a first threaded rod 302, a cylinder 303 and a protective box 304.

The four corners of the bottom plate 1 are provided with mounting holes. The outer side of the first threaded rod 302 is slidably connected to the inner side of the mounting hole. Therefore, when the bottom plate 1 is placed on the mounting plate 301, the first threaded rod 302 will pass through the mounting hole inside the bottom plate 1, and play a role in limiting the movement of the bottom plate 1 during disassembly and assembly.

[0033] The cylinder 303 is connected to the outside of the first threaded rod 302, and the protective box 304 is connected to the upper side of the mounting plate 301. The inner side of the cylinder 303 is provided with an internal thread, and the outer side of the first threaded rod 302 is threadedly connected to the inner side of the cylinder 303, and the lower end of the cylinder 303 abuts against the four corners of the upper side of the bottom plate 1. Therefore, after the bottom plate 1 is placed on the mounting plate 301 and the first threaded rod 302 passes through the mounting hole, the cylinder 303 is threadedly connected to the outer side of the first threaded rod 302 until the lower side of the cylinder 303 contacts the upper side of the bottom plate 1, so that the bottom plate 1 can be fixed to the upper end of the mounting plate 301, thereby fixing the antenna 2 to the middle position of the upper side of the bottom plate 1.

[0038] The rear end of the second threaded rod 402 abuts against the front end of the outer side of the antenna 2. Therefore, after the fixing ring 401 is slid to the desired position outside the antenna 2, the rotating handle 403 is rotated to drive the second threaded rod 402 to rotate in the threaded hole and move backward until the second threaded rod 402 moves backward to contact the outer side of the antenna 2, so that the fixing ring 401 can be fixed to the outer end of the antenna 2.

Therefore, when the two anti-interference layers 406 are fixed to the top of the fixing ring 401, the rubber pads on the adjacent sides of the two anti-interference layers 406 are in contact, so that the two anti-interference layers 406 can be kept sealed, preventing excessive dust from entering the anti-interference layer 406 and affecting the operation of the antenna 2.

[0042] Working principle: When in use, before the antenna 2 works, slide the fixing ring 401 to the required position outside the antenna 2, and then turn the rotating handle 403 to drive the second threaded rod 402 to rotate in the threaded hole and move backward until the second threaded rod 402 moves backward to contact the outside of the antenna 2, and then fix the fixing ring 401 to the outer end of the antenna 2, and then place the arc plate 405 under the anti-interference layer 406 on the left and right ends of the upper side of the fixing ring 401, and then pass the bolts 404 through the circular holes on the left and right ends inside the fixing ring 401 and then threadedly connect to the threaded groove under the arc plate 405, so that the arc plate 405 is fixed to the left and right ends above the fixing ring 401, and at the same time, the anti-interference layer 406 is fixed to the top of the fixing ring 401, so as to protect the antenna 2 in the anti-interference layer 406.
