[0034] The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0035] Referring to Figures 1-3 The present embodiment discloses a radome structure, comprising a cover body 101 and a blocking ring 102, the cover body 101 is used for mounting on a base 103, a plurality of stepped holes 104 are arranged on the cover body 101, and a fixing bolt 105 is threadedly connected in the stepped hole 104; the blocking ring 102 is rotatably installed on the cover body 101; a clearance slot 106 is arranged on the blocking ring 102, the clearance slot 106 is correspondingly arranged with the stepped hole 104, and a threaded hole is arranged on the base 103 for cooperating with the fixing bolt 105 to fix the cover body 101; a sealing assembly 107 is fixedly connected in the cover body 101, and the sealing assembly 107 is used for sealing the gap between the cover body 101 and the base 103.

[0036] In the embodiment, the blocking ring 102 is rotationally connected with the cover body 101. When it is needed to install the cover body 101 on the base 103, the blocking ring 102 is first rotated so that the clearance slot 106 arranged on the blocking ring 102 is moved to a position corresponding to the threaded hole, and the cover body 101 can be installed on the base 103 through cooperation of the fixing bolt 105 and the threaded hole. After the cover body 101 is installed on the base 103, the blocking ring 102 can shield the stepped hole 104 by rotating the blocking ring 102 so that the clearance slot 106 is no longer communicated with the stepped hole 104, thereby avoiding that the fixing bolt 105 installed in the stepped hole 104 is directly exposed to the outside and is easily corroded, which causes the cover body 101 to fall off. The fixing bolt 105 is located in the stepped hole 104 after being screwed with the threaded hole, thereby avoiding that the rotation of the blocking ring 102 is affected. After the cover body 101 is installed on the base 103, the sealing assembly 107 fixedly connected inside the cover body 101 can seal the gap between the cover body 101 and the base 103, thereby avoiding that water vapor and impurities enter the cover body 101 through the gap between the cover body 101 and the base 103. In the embodiment, the rotation of the blocking ring 102 can simultaneously shield all the stepped holes 104, thereby solving the problem that the operator needs to manually install the plugging block for protecting the fixing bolt 105 in each stepped hole in sequence in the prior art, which is time-consuming and laborious.

[0037] In some embodiments, the sealing assembly 107 includes a sealing ring 108 and a sealing protrusion 109 fixedly connected on a side of the sealing ring 108 close to the base 103. In the embodiment, the sealing protrusion 109 is an annular structure, and a plurality of sealing protrusions 109 are coaxially fixedly connected on the sealing ring 108 from top to bottom. The sealing ring 108 and the sealing protrusion 109 are made of rubber material. After the cover body 101 is installed on the base 103, the plurality of sealing protrusions 109 fixedly connected on the sealing ring 108 are deformed after being in contact with the base 103. The deformed sealing protrusions 109 can multiple seal the gap between the cover body 101 and the base 103, thereby avoiding that water vapor and impurities enter the cover body 101 through the gap between the cover body 101 and the base 103.

[0038] In some embodiments, the cover body 101 is provided with a mounting groove 110, and the sealing ring 108 is fixedly installed in the mounting groove 110. The sealing ring 108 is fixedly installed in the mounting groove 110, and the mounting groove 110 can further increase the contact area between the sealing ring 108 and the mounting groove 110, so that the connection between the sealing ring 108 and the cover body 101 is more stable.

[0039] In some embodiments, the sealing ring 108 is provided with a stepped groove 111 for cooperating with the base 103. By providing the stepped groove 111, the contact area between the sealing ring 108 and the base 103 can be further increased, thereby further improving the sealing effect of the sealing ring 108 and the sealing protrusion 109 on the gap formed between the cover 101 and the base 103.

[0040] In some embodiments, the blocking ring 102 is provided with a sliding groove 112, and a blocking part 113 for plugging the stepped hole 104 is slidingly installed in the sliding groove 112. The blocking part 113 is connected with a spring 114, and the sliding groove 112 is connected with the blocking part 113 through the spring 114. The blocking part 113 is correspondingly arranged with the stepped hole 104. The sliding groove 112 is provided in plurality, and the plurality of sliding grooves 112 are equidistantly arranged along the circumferential direction of the blocking ring 102. After the cover 101 is installed on the base 103, the blocking part 113 slidingly installed on the blocking ring 102 is moved to the corresponding position of the stepped hole 104 by rotating the blocking ring 102. Then, the blocking part 113 enters the stepped hole 104 and abuts against the fixing bolt 105 under the action of the spring 114. By arranging the blocking part 113 to cooperate with the stepped hole 104, the positioning of the blocking ring 102 and the further plugging of the stepped hole 104 can be achieved. When it is necessary to disassemble the fixing bolt 105, the blocking part 113 is moved into the sliding groove 112 and moves out of the stepped hole 104 by rotating the blocking ring 102. Then, the disassembly of the fixing bolt 105 can be achieved, and the spring 114 connected with the blocking part 113 and the sliding groove 112 is compressed.

[0041] In some embodiments, the blocking part 113 is provided with a ball cavity at the end away from the sliding groove 112, and a ball is rollingly connected in the ball cavity. By arranging the ball, the rolling connection between the blocking part 113 and the surface of the cover 101 can be changed from sliding connection during the rotation of the blocking ring 102, so as to avoid scratching the surface of the cover 101 by the blocking part 113 during the movement.

[0042] In some embodiments, the radome is provided with a heat dissipation hole. By arranging the heat dissipation hole, the air circulation inside the radome can be facilitated, so as to prevent the temperature inside the radome from being overheated due to the heat emitted by the electronic components, thereby preventing the damage to the electronic components.

[0043] In some embodiments, the heat dissipation hole is downwardly inclined. By arranging the heat dissipation hole to be downwardly inclined, the rainwater can be prevented from entering the cover 101 through the heat dissipation hole.

[0044] In some embodiments, a filter column 115 is detachably installed in the heat dissipation hole. The filter column 115 is used to filter dust and water vapor, so as to prevent the dust and water vapor from entering into the cover body 101 through the heat dissipation hole. A threaded groove is arranged in the heat dissipation hole, and the filter column 115 is threadedly connected with the heat dissipation hole through the threaded groove, so as to facilitate installation and replacement of the filter column 115.

[0045] In some embodiments, upper and lower ends of the chute 112 are provided with ring grooves, and sealing rings are installed in the ring grooves. In this embodiment, the ring grooves are arranged on the blocking ring 102, and the sealing rings are installed in the ring grooves and are in rotary sealing connection with the cover body 101. The sealing rings are used to further seal the gap between the cover body 101 and the blocking ring 102, so as to prevent dust and water vapor from entering into the stepped hole 104 through the gap between the cover body 101 and the blocking ring 102.

[0046] Although the preferred embodiments of the present application have been described, those skilled in the art who once know the basic creative concept can make further changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present application.
