[0004] In the prior art during use, the existing structure can adjust the omnidirectional angle through the arrangement of a gooseneck structure. However, the gooseneck structure is adjusted by extrusion deformation, resulting in the inability of the bent gooseneck to be quickly straightened. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a dual-mode omnidirectional antenna to solve the problem that the gooseneck structure is adjusted by extrusion deformation in the above background art, resulting in the inability of the bent gooseneck to be quickly straightened.

[0006] To solve the above technical problems, the utility model provides the following technical solution: a dual-mode omnidirectional antenna, including an antenna housing. An angle adjustment component is arranged at the bottom of the antenna housing, and the angle adjustment component is used to adjust the antenna angle according to requirements. An anti-detachment component is arranged at the bottom of the angle adjustment component, and the anti-detachment component is used to prevent the antenna from falling off through friction.

[0007] The angle adjustment component includes a rotating ball head, and combined shafts are installed on the front and back of the rotating ball head. A limiting frame is arranged on the outer side of the rotating ball head, and a spherical groove is opened on the inner side of the limiting frame.

[0011] Preferably, an opening is formed at the bottom of the rotating ball head, and a connecting wire is arranged inside the opening and the inner part of the connecting screw sleeve.

[0012] Preferably, combined grooves are formed on the front and back of the inner side of the spherical groove, and the combined grooves are located on the outer side of the combined shaft.

[0015] Compared with the prior art, the beneficial effects achieved by the present utility model are as follows:

[0016] First, by installing an angle - adjusting component, the present utility model can provide a limit for the inner rotating ball head by using the spherical groove inside the limiting frame. The rotating ball head can be flipped and adjusted inside. Since there is friction between the combined shaft and the combined groove, manual bending is required during angle adjustment, which is convenient for the staff to perform flipping adjustment and reset. The opening inside can keep the connecting wire normally connected without being affected by bending.

[0017] Second, the present utility model is equipped with an anti - detachment component. When the existing antenna is connected to external devices, it directly uses a threaded structure for combination. However, during long - term use, loosening will occur, affecting the signal. By installing an adjustment ring, installation positions can be provided for the outer and inner structures. The internal support spring pushes the limit ring and at the same time pushes the anti - slip ring against the surface of the device, thereby using the anti - slip structure to increase friction. The connection slider is used to connect the adjustment ring and the limit ring, ensuring that the internal support spring can push the anti - slip ring against the device. By using the anti - detachment component, the stability can be further improved in an anti - slip manner, avoiding signal transmission instability caused by loosening.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-4, A dual-mode omnidirectional antenna, including an antenna housing 1, an angle adjustment component is provided at the bottom of the antenna housing 1, and the angle adjustment component is used to adjust the antenna angle according to requirements. An anti-detachment component is provided at the bottom of the angle adjustment component, and the anti-detachment component is used to prevent the antenna from falling off through friction;

[0025] The angle adjustment component includes a rotating ball head 2, and combined shafts 203 are installed on the front and back of the rotating ball head 2. A limiting frame 3 is provided on the outside of the rotating ball head 2, and a spherical groove 301 is opened on the inside of the limiting frame 3.

[0026] The anti-detachment component includes an adjustment ring 501, and two connecting sliders 503 are installed on the inside of the adjustment ring 501. A limiting ring 504 is installed on the inside of the connecting slider 503, and a support spring 505 is provided at the top of the limiting ring 504. An anti-slip ring 5 is installed on the outside of the adjustment ring 501.

[0027] Through the above technical solution, the spherical groove 301 on the inside of the limiting frame 3 can provide a limit for the rotating ball head 2 on the inside. The rotating ball head 2 can be turned and adjusted on the inside. During the turning adjustment, since there is friction between the combined shaft 203 and the combined groove 302, it needs to be manually bent when adjusting the angle, which is convenient for the staff to perform turning adjustment and reset. The opening 204 on the inside can keep the connection line 401 normally connected without being affected by bending.

[0028] Through the above technical solution, by installing the adjustment ring 501, an installation position can be provided for the structures on the outside and inside. The internal support spring 505 pushes the limiting ring 504 and at the same time pushes the anti-slip ring 5 to closely adhere to the surface of the device, so as to increase the friction force by using the anti-slip structure. The connecting slider 503 is used to connect the adjustment ring 501 and the limiting ring 504 to ensure that the internal support spring 505 can push the anti-slip ring 5 to closely adhere to the device. By using the anti-detachment component, the stability can be further improved in an anti-slip manner, and the signal transmission stability caused by loosening can be avoided.

[0029] Specifically, a telescopic antenna 101 is provided on the inside of the antenna housing 1, and an antenna cap 102 is installed on the top of the telescopic antenna 101.

[0030] Through the above technical solution, the telescopic antenna 101 can change the length of the antenna, and the tube antenna cap 102 can seal the hole on the top.

[0031] Specifically, a stabilizing disk 202 is installed on the top of the rotating ball head 2, and a connecting screw sleeve 201 is installed on the top of the stabilizing disk 202. The connecting screw sleeve 201 is located at the bottom of the antenna housing 1.

[0032] Through the above technical solution, the stabilizing disk 202 can increase the installation stability and can be connected to the antenna housing 1 by using the connecting sleeve 201.

[0033] Specifically, an opening 204 is formed at the bottom of the rotating ball head 2, and a connecting wire 401 is arranged inside the opening 204 and the connecting sleeve 201.

[0034] Through the above technical solution, the inside of the opening 204 runs through to provide an installation position for the connecting wire 401.

[0035] Specifically, combined grooves 302 are formed on the front and back sides inside the spherical groove 301, and the combined grooves 302 are located outside the combined shaft 203. A rotating base 303 is movably arranged at the bottom of the limiting frame 3, and movable grooves 304 are formed on both sides of the rotating base 303. The movable grooves 304 are located outside the connecting slider 503. A fixed sleeve 305 is installed at the bottom of the rotating base 303.

[0036] Through the above technical solution, the combined grooves 302 are used to limit the combined shaft 203 to assist the rotating ball head 2 in flipping and adjusting. The rotating base 303 can assist the limiting frame 3 at the top in rotating and adjusting. The fixed sleeve 305 is used to connect to the threaded structure of the device.

[0037] Specifically, coil modules 4 are arranged on the inner sides of the upper and lower ends of the connecting wire 401, and a dual-frequency circuit board is arranged above the coil modules 4. A radio frequency connector 402 is installed at the end of the connecting wire 401, and a connecting head 403 is installed at the bottom of the radio frequency connector 402. A fixed bearing 404 is installed on the radio frequency connector 402, and the fixed bearing 404 is located inside the fixed sleeve 305.

[0038] Through the above technical solution, the coil modules 4 cooperate with the dual-frequency circuit board to achieve dual-frequency signal transmission. The radio frequency connector 402 is connected to the interface of the device through the connecting head 403. The fixed bearing 404 can ensure that the fixed sleeve 305 rotates normally for installation after the connecting head 403 is inserted.

[0039] Specifically, anti-slip blocks 502 are installed at the tops of the front and back sides of the adjusting ring 501, and the anti-slip blocks 502 are located on the front and back sides of the rotating base 303.

[0040] Through the above technical solution, the anti-slip blocks 502 are used to provide a grip for the user to assist in controlling the sliding adjustment of the adjusting ring 501.

[0041] In use, first, the connection head 403 is correspondingly inserted into the device interface area, and then the fixing sleeve 305 is grasped and rotated for insertion. During the rotation process, the anti-slip block 502 is grasped to control the internal limit ring 504 to compress the support spring 505 to avoid the increase in installation difficulty caused by friction during the rotation process. After continuously rotating the fixing sleeve 305 for installation, the anti-slip block 502 can be released, and the internal support spring 505 can be used to push the anti-slip ring 5 into contact with the device to maintain an anti-slip state. Then, the antenna housing 1 is controlled to be flipped according to requirements, and the rotating ball head 2 will rotate along the spherical groove 301, so as to realize the flipping adjustment of the antenna housing 1.
