Existing wireless network cards are foldable and rotating, and the antenna adjustment angle range is small. It is also impossible to ensure that the antenna will be fixed for a long time after adjustment. Utility Model Content

[0004] The problem solved by the utility model is to provide a high-gain antenna-type USB network card with flexible angle adjustment, which solves the technical problem of improving the connection strength and stability of the wireless network by equipping the wireless network card with an antenna when in use. The existing wireless network card is a folding and rotating adjustment type, the antenna adjustment angle range is small, and it is impossible to ensure that the antenna is fixed for a long time after adjustment.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A high-gain antenna-type USB network card with flexible angle adjustment includes a network card body, a USB connector, a limiting ring seat, a swivel seat and a telescopic antenna. The USB connector is provided at one end of the network card body, and a limiting ring seat is installed at the other end of the network card body. The swivel seat is rotatably installed in the limiting ring seat, and the telescopic antenna is installed on the swivel seat.

[0007] Preferably, the limiting ring seat includes a first limiting ring connected to the network card body, and the bottom side of the first limiting ring is connected to the second limiting ring through an arc-shaped connecting block.

[0008] Preferably, the swivel seat is connected to the network card body via a bearing, and a swivel block is installed on the outside of the swivel seat.

[0009] Preferably, a moving contact is installed through the rotating seat, and the moving contact is connected to the telescopic antenna.

[0010] Preferably, a static contact ring is installed in the network card body, and a plurality of protrusions are arranged at equal angles in the static contact ring. The end of the moving contact is located in the static contact ring, and the moving contact contacts the protrusions.

[0011] Preferably, an annular groove is provided on the inner side of the rotating seat, a spring is installed in the annular groove, and the spring is connected to the slip ring, and the outer side of the rotating seat contacts the inner wall of the second limiting ring.

[0012] The beneficial effect of the utility model is that the telescopic antenna can be rotated by rotating the rotating seat in the limiting ring seat, thereby facilitating the rotation of the telescopic antenna to different directions, thereby achieving flexible adjustment of the installation angle of the telescopic antenna and ensuring the stability of the wireless connection.

[0013] During the rotation process, the spring is compressed by pressing the swivel seat to separate the swivel seat from the second limiting ring, which is convenient for the subsequent rotation of the swivel seat. After the rotation is completed, the spring returns to its original state, and the swivel seat contacts the inner wall of the second limiting ring to limit the swivel seat, which is convenient for the rotation and limited fixation of the swivel seat.

[0020] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Specific examples are given below.

[0022] See also Figures 1 to 4 A high-gain antenna-type USB network card with flexible angle adjustment includes a network card body 1, a USB connector 2, a limiting ring seat 3, a swivel seat 4 and a telescopic antenna 5. The USB connector 2 is provided at one end of the network card body 1, and a limiting ring seat 3 is installed at the other end of the network card body 1. The swivel seat 4 is rotatably installed in the limiting ring seat 3, and the telescopic antenna 5 is installed on the swivel seat 4.

[0023] The limiting ring seat 3 includes a first limiting ring 6 connected to the network card body 1, and the bottom side of the first limiting ring 6 is connected to the second limiting ring 8 through an arc-shaped connecting block 7. The swivel seat 4 is connected to the network card body 1 through a bearing 9. A swivel block 14 is installed on the outside of the swivel seat 4. A moving contact 10 is installed through the swivel seat 4, and the moving contact 10 is connected to the telescopic antenna 5. A static contact ring 11 is installed in the network card body 1, and a plurality of protrusions 12 are arranged at equal angles in the static contact ring 11. The end of the moving contact 10 is located in the static contact ring 11, and the moving contact 10 is in contact with the protrusion 12, so that during the rotation of the swivel seat 4, the moving contact 10 rotates in the static contact ring 11 and always keeps in contact with the protrusion 12 of the static contact ring 11. An annular groove is provided on the side, and a spring 13 is installed in the annular groove, and the spring 13 is connected to the slip ring 15. The outer side of the swivel seat 4 contacts the inner wall of the second limiting ring 8. The spring 13 is compressed by pressing the swivel seat 4 to realize the separation of the swivel seat 4 and the second limiting ring 8, which is convenient for the subsequent rotation of the swivel seat 4. After the rotation is completed, the spring 13 is restored to its original state, and the swivel seat 4 is in contact with the inner wall of the second limiting ring 8 to limit the swivel seat 4, which is convenient for the rotation and limited fixation of the swivel seat 4. By rotating the swivel seat 4 in the limiting ring seat 3, the telescopic antenna 5 is driven to rotate, which is convenient for rotating the telescopic antenna 5 to different directions, and the flexible adjustment of the installation angle of the telescopic antenna 5 is realized while ensuring the stability of the wireless connection.
