Description

Technical Field

[0001] The utility model relates to the technical field of omnidirectional antennas, and specifically relates to a dual-frequency sleeve omnidirectional antenna. Background Technique

[0002] An antenna has different radiation or reception capabilities in different directions in space, which is the directivity of the antenna. According to different directivities, antennas are divided into omnidirectional and directional types. In the vertical radiation pattern, it is manifested as a beam with a certain width. Generally, the smaller the lobe width, the greater the gain. Omnidirectional antennas are generally used in the station types of suburban and county large-area systems in mobile communication systems, with a large coverage range.

[0003] Most of the existing omnidirectional antennas are designed for different operating frequency bands, and the size and volume of the antennas are generally relatively large. Most sleeve dipole antennas only meet a narrow frequency band, and there are still some disadvantages to a certain extent. When using an omnidirectional antenna, it needs to be assembled first. The assembly steps of the existing omnidirectional antennas are often relatively cumbersome and not convenient enough. This makes it inconvenient for users to assemble the outer sleeve and the inner sleeve on the surface of the positioning block respectively when using the omnidirectional antenna, greatly reducing the convenience of using the omnidirectional antenna; the omnidirectional antenna is easily interfered with during use, resulting in a poor signal of the omnidirectional antenna. The anti-interference performance of the existing omnidirectional antennas is not good enough. This makes it impossible to perform anti-interference processing between the outer sleeve and the inner sleeve when using the omnidirectional antenna, reducing the signal stability and use effect when using the omnidirectional antenna; the omnidirectional antenna does not have the function of rapid heat dissipation during use, which easily leads to the phenomenon that the service life of the omnidirectional antenna is affected due to the too high temperature inside the outer sleeve during the use of the omnidirectional antenna.

The convenient assembly part 403 is provided on the surfaces of the positioning blocks 101, outer sleeves 102 and inner sleeves 103. The convenient assembly part 403 is composed of a positioning clip 4031 and a positioning slot 4032.

Positioning slots 4032 are formed on the inner walls of the positioning blocks 101. The surfaces of the positioning slot 4032 and the positioning clip 4031 are clamped and matched with each other.

[0026] During implementation, the outer sleeve 102 and the inner sleeve 103 move to one side of the positioning block 101 respectively. At this time, the outer sleeve 102 and the inner sleeve 103 drive the assembly block 402 to slide inside the assembly groove 401.

[0027] Furthermore, as Figure 2 and Figure 4 shown, anti-interference mechanisms 3 are provided on the surfaces of the outer sleeve 102 and the inner sleeve 103. The inside of the anti-interference mechanism 3 includes arc-shaped cards 301, groove bodies 302 and anti-interference parts 303. The anti-interference parts 303 are provided on the surfaces of the outer sleeve 102 and the inner sleeve 103. The anti-interference part 303 is composed of a stretching spring 3031, a first anti-interference layer 3032 and a second anti-interference layer 3033. The first anti-interference layer 3032 is installed on the inner walls of the inner sleeve 103, and the second anti-interference layer 3033 is installed on the inner walls of the outer sleeve 102. The surface of the second anti-interference layer 3033 is in contact with the surface of the first anti-interference layer 3032. Groove bodies 302 are provided on the surfaces of the outer sleeve 102. Arc-shaped cards 301 are provided inside the groove bodies 302. The arc-shaped cards 301 are slidably matched with the inner walls of the groove bodies 302, and the arc-shaped cards 301 are clamped and matched with the surface of the inner sleeve 103. Stretching springs 3031 are installed inside the groove bodies 302. One end of the stretching spring 3031 is fixed to the surface of the arc-shaped card 301.

[0028] During implementation, under the elastic force of the stretching spring 3031 inside the groove body 302, the arc-shaped card 301 is driven to move, so that the arc-shaped card 301 is clamped to the surface of the inner sleeve 103. At this time, under the combined action of the second anti-interference layer 3033 and the first anti-interference layer 3032, anti-interference treatment is carried out between the outer sleeve 102 and the inner sleeve 103, avoiding the phenomenon that the outer sleeve 102 and the inner sleeve 103 are interfered with during the use of the omnidirectional antenna, which affects the normal use of the omnidirectional antenna, so as to achieve the anti-interference function of the omnidirectional antenna.

[0029] Furthermore, as Figure 2 and Figure 3As shown, the interior of the outer sleeve 102 and the inner sleeve 103 is provided with a heat dissipation and damage prevention mechanism 2, and the interior of the heat dissipation and damage prevention mechanism 2 includes a mounting slider 201, a fixed slide groove 202, a heat dissipation box 203, a heat conduction hole 204 and a heat conduction plate 205. The outer sleeve 102 and the inner sleeve 103 are both installed with a heat dissipation box 203, and a heat conduction plate 205 for heat conduction treatment of the inner part of the outer sleeve 102 and the inner sleeve 103 is placed inside the heat dissipation box 203. The surface of the heat conduction plate 205 is installed with a mounting slider 201, and the inner wall of the heat dissipation box 203 is provided with a fixed slide groove 202, and the fixed slide groove 202 and the surface of the mounting slider 201 slide with each other. The inner wall of the heat dissipation box 203 and the outer sleeve 102 are both provided with heat conduction holes 204 with equal intervals, and the heat conduction holes 204 are connected with the interior of the heat dissipation box 203.

[0030] During implementation, the user places the heat conducting plate 205 inside the heat dissipation box 203. At this time, the heat conducting plate 205 drives the installation slider 201 to slide inside the fixed slide groove 202. Under the joint action of the installation slider 201 and the fixed slide groove 202, the heat conducting plate 205 is guided so that the heat conducting plate 205 is installed inside the heat dissipation box 203. At this time, under the action of the heat conducting plate 205, the heat inside the outer sleeve 102 and the inner sleeve 103 is exported, so that the heat is exported to the inside of the outer sleeve 102 and the inner sleeve 103 through the heat conducting holes 204, and the inside of the outer sleeve 102 and the inner sleeve 103 are efficiently cooled, so as to realize the function of rapid heat dissipation of the omnidirectional antenna.

[0031] Working principle: When in use, first place the antenna body 1 at the designated position, and then the user respectively puts the outer sleeve 102 and the inner sleeve 103 onto the surface of the antenna body 1, so that the outer sleeve 102 and the inner sleeve 103 move to one side of the positioning block 101, and then the outer sleeve 102 and the inner sleeve 103 drive the assembly block 402 to slide inside the assembly groove 401, and the outer sleeve 102 and the inner sleeve 103 are guided by the combined action of the assembly groove 401 and the assembly block 402. 02 drives the positioning card 4031 to be clamped into the inside of the positioning card slot 4032, and under the clamping action of the positioning card 4031 and the positioning card slot 4032, the outer sleeve 102 and the inner sleeve 103 are respectively installed on the surface of the positioning block 101, and the assembly of the omnidirectional antenna is completed to realize the function of convenient assembly of the omnidirectional antenna, so that when the omnidirectional antenna is used, it is convenient for the user to assemble the outer sleeve 102 and the inner sleeve 103 respectively on the surface of the positioning block 101, which greatly improves the convenience of the omnidirectional antenna when in use.

[0032] Subsequently, when the outer sleeve 102 and the inner sleeve 103 are respectively installed on the surface of the positioning block 101, at this time, the arc-shaped clamp 301 is driven to move under the elastic force of the extension spring 3031 inside the groove body 302, so that the arc-shaped clamp 301 is clamped to the surface of the inner sleeve 103. At this time, under the joint action of the second anti-interference layer 3033 and the first anti-interference layer 3032, anti-interference treatment is performed between the outer sleeve 102 and the inner sleeve 103, thereby avoiding the phenomenon that the outer sleeve 102 and the inner sleeve 103 are interfered with during the use of the omnidirectional antenna and affecting the normal use of the omnidirectional antenna, so as to realize the anti-interference function of the omnidirectional antenna, so that the omnidirectional antenna can perform anti-interference treatment between the outer sleeve 102 and the inner sleeve 103 when in use, so that the signal stability of the omnidirectional antenna is higher and the use effect is better when in use.

[0033] Subsequently, since the outer sleeve 102 is arranged on the outside of the inner sleeve 103 and is not in direct contact with the surface of the inner sleeve 103, the current on the surface of the outer sleeve 102 is formed by coupling with the field generated on the surface of the inner sleeve 103. The outer sleeve 102, the inner sleeve 103 and the corresponding positioning block 101 constitute a dual-band ultra-wideband oscillator, which is fed by the coupling of the outer sleeve 102 and the inner sleeve 103, thereby realizing the dual-band bandwidth and widened bandwidth of the antenna body 1.

[0034] Subsequently, when the heat inside the outer sleeve 102 and the inner sleeve 103 continues to rise, the user places the heat conducting plate 205 inside the heat dissipation box 203. At this time, the heat conducting plate 205 drives the installation slider 201 to slide inside the fixed slide groove 202. Under the joint action of the installation slider 201 and the fixed slide groove 202, the heat conducting plate 205 is guided so that the heat conducting plate 205 is installed inside the heat dissipation box 203. At this time, under the action of the heat conducting plate 205, the heat inside the outer sleeve 102 and the inner sleeve 103 is dissipated. The heat is conducted out of the outer sleeve 102 and the inner sleeve 103 through the heat conducting holes 204, and the inner sleeve 102 and the inner sleeve 103 are efficiently heat-dissipated to realize the function of rapid heat dissipation of the omnidirectional antenna, so that the heat inside the outer sleeve 102 and the inner sleeve 103 can be quickly conducted out of the omnidirectional antenna when in use, thereby avoiding the phenomenon that the service life of the omnidirectional antenna is affected by the excessively high temperature inside the outer sleeve 102 during the use of the omnidirectional antenna, and finally completing the use of the omnidirectional antenna.
