[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In this invention, by setting up a protective shell and a cover plate, pulling the cover plate releases the antenna body from its confinement, allowing the antenna body to be placed flat inside the protective shell. Under the action of the elastic mechanism, the sliding plate moves closer to the mobile terminal, thereby causing the sealing plate to seal the bottom of the protective shell and the cover plate to seal the top of the protective shell. This allows the antenna body to be sealed inside the protective shell without disassembling it. The protective shell, cover plate, and sealing plate protect the antenna body, achieving the effect of protecting the antenna body without disassembly.

The sliding plate drives the cover plate to move closer to the antenna body through the connecting plate, and then the antenna body is locked in place by the slot, thereby squeezing and fixing the antenna body to prevent it from shaking. This achieves the effect of increasing the stability of the antenna body. The upper and lower parts of the protective shell are provided with openings to facilitate the extension of the antenna body and heat dissipation, and also to facilitate wire insertion, thereby increasing convenience.

The antenna body 3 is connected to one side of the rotating block 203. The fixed end 201 and the connecting end 1 can be fixed together by threads to enable signal transmission. When needed, the fixed end 201 can be detached from the connecting end 1 by twisting the fixed end 201. The fixed end 201 can rotate between the limiting block 202 and the rotating block 203. At the same time, the limiting block 202 holds the rotating block 203 in place to prevent them from separating. They are connected by a wire to facilitate signal transmission.

[0023] The antenna body 3 is provided with a protective shell 4. A cover plate 5 is slidably connected to the upper surface of the protective shell 4. A slot 12 is provided on one side of the cover plate 5. The inner wall of the slot 12 is in contact with the antenna body 3. A sealing block 13 is also installed on the upper part of the protective shell 4. A mounting plate 14 is fixedly connected to the side of the protective shell 4. The slot 12 is used to restrict the position of the antenna body 3 to prevent it from shaking. When the cover plate 5 is closed, the sealing block 13 can block the slot 12 to increase the sealing effect. The mounting plate 14 is provided with bolt holes, and the mounting plate 14 can be fixed to the mobile terminal by bolts. It can be disassembled when needed.

[0024] Both ends of the cover plate 5 are fixedly installed with connecting plates 6. One side of the connecting plate 6 is slidably connected to the protective shell 4. A sliding plate 7 is fixedly connected to the outer surface of the connecting plate 6. A sealing plate 8 is fixedly connected to the upper part of the sliding plate 7. The outer surface of the sealing plate 8 is slidably connected to the protective shell 4. An elastic mechanism 9 is provided on the inner wall of the sliding plate 7. The connecting end 1 is connected to the mobile terminal. The antenna body 3 is connected to the connecting end 1 by the rotating mechanism 2, so that the antenna body 3 can receive signals and transmit them to the mobile terminal, or send signals out. The protective shell 4 is clamped on both sides by the two connecting plates 6, which can increase the stability of the cover plate 5. The upper and lower parts of the protective shell 4 are provided with openings to allow the antenna body 3 to extend and dissipate heat. When closed, the cover plate 5 can seal the upper part of the protective shell 4, and the sealing plate 8 can seal the lower part of the protective shell 4.

[0025] The elastic mechanism 9 includes a fixed rod 901, one end of which is fixedly connected to the fixed plate 10, and the outer surface of the fixed rod 901 is slidably connected to the sliding plate 7. In use, the end of the fixed rod 901 away from the fixed plate 10 presses against the mobile terminal, thereby fixing the fixed rod 901. The sliding plate 7 can slide on the fixed rod 901. A spring 902 is sleeved on the outer surface of the fixed rod 901. One end of the spring 902 is fixedly connected to the fixed plate 10, and the other end of the spring 902 is fixedly connected to the sliding plate 7. The spring 902 can provide the sliding plate 7 with an elastic force away from the fixed plate 10, so that when closed, the sealing plate 8 can seal the bottom of the protective shell 4.

[0027] It should be noted that in actual use, under the action of spring 902, the sliding plate 7 moves away from the fixed plate 10. The sliding plate 7 drives the cover plate 5 to move closer to the antenna body 3 through the connecting plate 6, and then the antenna body 3 is clamped by the slot 12, thereby squeezing and fixing the antenna body 3 to prevent the antenna body 3 from shaking, thus achieving the effect of increasing the stability of the antenna body 3. The upper and lower parts of the protective shell 4 are provided with openings to facilitate the extension and heat dissipation of the antenna body 3, and at the same time facilitate the insertion of wires to increase convenience.

[0028] When the mobile terminal needs to be carried away or stored away from use, disconnect the connecting cable from the mobile terminal, pull the cover plate 5 to move the cover plate 5 away from the mobile terminal, thereby releasing the restriction on the antenna body 3. Rotate the antenna body 3, and the two antenna bodies 3 rotate towards the middle, placing them flat inside the protective shell 4. Release the cover plate 5, and under the action of the spring 902, drive the sliding plate 7 to move closer to the mobile terminal, thereby driving the sealing plate 8 to seal the bottom of the protective shell 4, and at the same time driving the cover plate 5 to seal the top of the protective shell 4, so that the antenna body 3 can be sealed inside the protective shell 4 without disassembling the antenna body 3. At the same time, the protective shell 4, cover plate 5 and sealing plate 8 protect the antenna body 3 to prevent damage to the antenna body 3, achieving the effect of protecting the antenna body 3 without disassembly. It can also seal the interface of the mobile terminal to prevent dust from accumulating during long-term non-use.
