[0034] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0035] See also Figures 1 to 6 , is a foldable antenna structure as the best embodiment of the utility model, including a base 10, an antenna housing 20, and a locking mechanism 30. One end of the antenna housing 20 is arranged on the base 10 and is rotatably connected to the base 10; the locking mechanism 30 is arranged at the other end of the antenna group, and the locking mechanism 30 is used to prevent the antenna housing 20 and the base 10 from rotating. A foldable antenna structure of the utility model can adjust the position of the antenna housing 20 by setting the antenna housing 20 rotatably connected to the base 10. When the RFID function needs to be used, the antenna housing 20 is rotated and locked by the locking assembly to prevent the antenna housing 20 from rotating. When the paper is needed to be taken and placed, the locking mechanism 30 can be unlocked and the antenna housing 20 can be rotated to avoid any impact.

[0036] The antenna structure also includes an antenna component arranged in the antenna housing 20, wherein the antenna component adopts an RFID antenna. How the RFID antenna is arranged in the antenna housing 20 is a prior art and will not be described in detail. After the line of the RFID antenna passes through the outer shell, a certain length can be reserved to accommodate the rotation of the antenna housing 20.

[0037] Please refer to Figure 2 , 5 , one end of the antenna housing 20 is limited to the base 10 by a first bolt 40; a first rotating shaft 11 is provided on the base 10, and one end of the antenna housing 20 is provided in a first mounting hole 21 matched with the first rotating shaft 11, the first rotating shaft 11 is provided with a first internal threaded hole along the central axis direction thereof, the first mounting hole 21 is sleeved on the first rotating shaft 11, the first bolt 40 is locked on the first rotating shaft 11 to limit the antenna housing 20 from being separated from the first rotating shaft 11, and the first mounting hole 21 is provided in an elastic groove 22 connected to the outer wall along the central axis direction thereof; the inner diameter of the first mounting hole 21 is equal to or smaller than the outer diameter of the first rotating shaft 11, and when the inner diameter of the first mounting hole 21 is smaller than the outer diameter of the first rotating shaft 11, the elastic groove 22 can play a damping effect, so the antenna housing 20 will rotate only under the action of external force.

[0038] Please refer to Figure 1 , 5The antenna housing 20 has two states, one of which is a use state and the other is a non-use state (i.e., a paper placing operation when changing paper). In the use state, paper passes between the antenna housing 20 and the paper discharge cover 50; a protrusion 23 is provided on the antenna housing 20, and a first limiting groove 12 and a second limiting groove 13 cooperating with the protrusion 23 are provided on the base 10. The protrusion 23 cooperates with the first limiting groove 12 or the second limiting groove 13 to correspond to the use state or the non-use state of the antenna housing 20. When the RFID antenna needs to be used, Rotate the antenna housing 20 so that the protrusion 23 is embedded in the first limiting groove 12, which can prevent the antenna housing 20 from rotating on its own to a limited extent. In conjunction with the locking of the locking mechanism 30, the antenna housing 20 is securely set and is in a use mode. When paper is needed to be taken or placed, it is in a non-use mode, unlock the locking mechanism 30, rotate the antenna housing 20, and allow the protrusion 23 to be embedded in the second limiting groove 13. The protrusion 23 cooperates with the second limiting groove 13, and under the damping effect, the antenna housing 20 is maintained.

[0039] For details, please refer to Figure 3 The antenna structure is mounted on the paper discharge cover 50, the base 10 is disposed on the paper discharge cover 50, and the locking mechanism 30 can be locked on the paper discharge cover 50. An installation cavity 24 for installing the locking mechanism 30 is disposed inside the end of the antenna housing 20 away from the base 10, and a U-shaped groove 25 is disposed inside the installation cavity 24; the installation cavity 24 and the groove 25 are formed by a plurality of support arms disposed inside the antenna housing 20 as required. A locking hole 53 for locking the locking mechanism 30 is provided on the paper outlet cover 50. The locking mechanism 30 includes a locking buckle that can slide in the installation cavity 24 and an elastic member arranged between the locking buckle and the groove 25. The elastic member adopts a spring and always generates elastic potential energy for the locking buckle. A locking step is provided under the locking buckle. When the antenna housing 20 is in use, the locking buckle passes through the locking hole 53. Under the action of the elastic member, the inner side of the paper outlet cover 50 is hooked through the locking step. When it needs to be unlocked, the locking buckle is pressed and moved backward to make the locking step separate from the inner side of the disposal cover, and the locking buckle moves upward through the locking hole 53.

[0040] A buckle portion 14 and a first mounting portion 15 are provided on the base 10, a positioning step 51 matched with the buckle portion 14 is provided on the paper discharge cover 50, a second mounting portion 52 for fixing the first mounting portion 15 is provided on the paper discharge cover 50, and the first mounting portion 15 is locked on the first mounting portion 15 by a second bolt 60; a second internal threaded hole matched with the second bolt 60 is provided on the second mounting portion 52, the second bolt 60 passes through the first mounting portion 15 and is threadedly connected with the second mounting portion 52, and after the second bolt 60 is locked in place, the buckle portion 14 hooks the positioning step 51; the buckle is matched with the positioning step 51, and then the base 10 is locked by the second bolt 60, so that the base 10 can be quickly installed on the paper discharge cover 50, thereby improving the installation efficiency.

[0041] The second mounting portion 52 is cylindrical, and the first mounting portion 15 is located at one side of the second mounting portion 52 and is provided with an annular step 151 that cooperates with the second mounting portion 52 , so as to quickly position the base 10 on the paper discharge cover 50 and facilitate the locking of the second bolt 60 .

[0042] The working principle of the antenna structure of the utility model is as follows:

[0043] When the RFID antenna function is needed, the RFID antenna housing 20 can be folded closed by using the first rotating shaft 11 and through the protrusion 23 and the first limiting groove 12, and then the RFID antenna housing 20 is fixed by the locking step of the locking buckle.

[0044] To sum up, the utility model has a retractable antenna structure, which can adjust the position of the antenna shell by setting an antenna shell rotatably connected to the base. When the RFID function needs to be used, the antenna shell is rotated and locked by a locking assembly to prevent the antenna shell from rotating. When paper is needed, the locking mechanism can be unlocked and the antenna shell can be rotated to avoid impact. At the same time, the base can be quickly installed by using a snap-on part and a locking step.

[0045] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
