[0027] Please see Figure 1-7 This utility model provides a technical solution:

[0028] A replaceable mobile phone antenna includes a mobile phone body 1, an antenna 2, and an antenna connector 7. The mobile phone connector 7 is provided on the top side inside the mobile phone body 1. A slot is provided on the top side of the mobile phone body 1 corresponding to the mobile phone connector 7. The antenna 2 is connected to the mobile phone connector 7 by plugging and unplugging.

[0029] Specifically, it should be noted that after antenna 2 is inserted into antenna connector 7, how antenna 2 is used is a mature existing technology, and its internal structure and working principle will not be described in detail here.

[0030] Furthermore, the surface of the antenna 2 is provided with a first rubber sealing strip 3. The bottom of the first rubber sealing strip 3 contacts the top of the mobile phone body 1. When the antenna connector 7 connects the antenna 2 by plugging and unplugging, the first rubber sealing strip 3 at the antenna 2 will contact the top of the mobile phone body 1, sealing the gap between the mobile phone body 1 and the antenna 2 to prevent moisture and dust from entering.

[0031] Furthermore, a second rubber sealing strip 6 is provided at the bottom of the outer surface of the sealing cover 4. The bottom of the second rubber sealing strip 6 contacts the top of the mobile phone body 1. The provision of the second rubber sealing strip 6 will improve the sealing performance of the sealing cover 4 and better block moisture and dust.

[0032] Furthermore, a fixing groove 8 is provided on the outside of the slot of the mobile phone body 1. A damping rotating shaft 11 is fixedly connected to the bottom center of the fixing groove 8. A large rotating block 5 is provided on the top of the damping rotating shaft 11. A sealing cover 4 is provided on the other side of the large rotating block 5. The sealing cover 4 is located on the top of the fixing groove 8.

[0033] Furthermore, a rotating groove 9 is provided at one end of the outer side of the fixed groove 8, and a small rotating block 12 is slidably connected inside the rotating groove 9. The top of the small rotating block 12 is connected to the large rotating block 5.

[0034] Furthermore, slots 10 are provided at both ends of the rotating groove 9, and a locking block 13 is provided on the outer side of the small rotating block 12. The locking block 13 is engaged with the slot 10.

[0035] Specifically, the sealing cover 4 blocks moisture and dust after the antenna 2 is removed, preventing them from entering the inside of the phone body 1. During the rotation of the large rotating block 5, the small rotating block 12 will rotate at the rotating groove 9. When the small rotating block 12 rotates to both ends of the rotating groove 9, the locking block 13 on the small rotating block 12 will engage with the locking groove 10, thus fixing the sealing cover 4. This prevents the sealing cover 4 from moving when sealing the slot. If the sealing cover moves, moisture and dust will enter the inside of the phone body, affecting the sealing performance of the sealing cover.

[0036] Furthermore, since there are slots 10 on both sides of the rotating groove 9, when the user rotates the sealing cover 4, the large rotating block 5 will rotate via the damping shaft 11, causing the sealing cover 4 to rotate. During the rotation, when the small rotating block 12 rotates to one end, the following may occur: Figure 3 As shown, antenna 2 can be inserted at this time. When antenna 2 is pulled out, it is rotated in the opposite direction. When the small rotating block 12 rotates to the other end, the sealing cover 4 will cover the slot to seal the slot.
