TECHNICAL FIELD
[0001] The utility model relates to the field of antenna, especially a kind of rotary lifting folding antenna. BACKGROUND
[0002] To ensure that the antenna has excellent signal receiving performance, the antenna receiving oscillator and the reflector net need to maintain a certain distance. However, due to the large size of the oscillator and the reflector net, the overall volume of the antenna exceeds the predetermined packaging specification, thereby causing a significant increase in packaging and transportation costs. To address the problem of excessive packaging volume, the existing technology mostly adopts a detachable design scheme for the oscillator and the reflector net. However, such detachable antennas require the use of tools for installation during customer installation and use, resulting in a complex installation process and a high risk of deviation due to operational errors, which affects the normal use effect. In addition, the gain performance of the current antenna is not ideal, and the standing wave ratio is high, which is a key problem that needs to be improved. SUMMARY
[0003] To solve the problems existing in the prior art, the utility model provides a rotary lifting folding antenna, which can be folded during packaging and unfolded during use, effectively solving the problems of excessive packaging volume and high transportation cost, without the need for tool assistance for installation, and improving the gain and standing wave ratio.

[0005] Further, the utility model comprises a connecting assembly and a reflector net; the oscillator base is connected to the reflector net through the connecting assembly.
[0006] Further, the oscillator base comprises an oscillator box, a first director base, and a second director base; the first director base and the second director base are detachably connected to the oscillator box; at least one set of first platforms and second platforms are formed on the first director base and the second director base, respectively.
[0007] Further, the vibrator base further comprises at least two fixing members; two ends of the vibrator box are fixedly connected with the first director base and the second director base through the fixing members.
[0008] Further, the first director base and the second director base are respectively provided with mounting grooves.
[0009] Further, one end of the connecting rod is detachably connected to the vibrator box; the other end of the connecting rod is embedded in the mounting groove; the connecting rod is fixedly contacted with the first director or the second director.
[0010] Further, the connecting rod is in a slope type curved connection structure with high middle and low left and right ends; the connecting rod comprises a first connecting rod end, a second connecting rod end and a third connecting rod end; the third connecting rod end is provided with a groove for facilitating mounting with the vibrator box; the first director base and the second director base are respectively provided with mounting grooves; the connecting rod passes through and is mounted in the vibrator box; the first connecting rod end and the second connecting rod end are embedded in the mounting grooves; the first connecting rod end is fixedly contacted with the first director; the second connecting rod end is fixedly contacted with the second director.
[0011] Further, the first platform or the second platform is provided with at least one limiting block; the limiting block is stopped and contacted with the first director or the second director in the everted unfolded state.
[0012] Further, the limiting block is in a straight face trapezoidal structure with narrow upper part and wide lower part; when the first director or the second director is independently rotated and switched between the preset folded state and unfolded state, the first director or the second director can cross the limiting block.

[0014] The utility model discloses beneficial effects:
[0015] 1. The first platform and the second platform have height difference in the height direction, so that the first director and the second director do not interfere with each other when being moved at the same time or respectively. When the rotating lifting folding antenna needs to be used, the first director and the second director only need to be moved away from the direction of the vibrator box, so that they are in the outward turning unfolded state, at this time, with the limiting block arranged on the first platform and the second platform, the first director and the second director can be stably fixed, and when the rotating lifting folding antenna needs to be packaged, the first director and the second director only need to be moved towards the direction close to the vibrator box, so that they present the inward folding state.

The gain of the utility model can reach 5-8.5dBi, and the standing wave ratio is also improved and controlled within 2.5. BRIEF DESCRIPTION OF DRAWINGS

The first director base 12 is provided with two symmetrically arranged first directors 2. Correspondingly, the second director base 13 is provided with two symmetrically arranged second directors 3. The first directors 2 and the second directors 3 are both in the shape of "Y".
[0034] In the embodiment, the dipole base 1 is provided with a group of two symmetrically arranged first platforms 5 at one end.

The first directors 2 or the second directors 3 are in contact with the connecting pin 42.
[0037] Through the pivoting mode of the embodiment, the first directors 2 or the second directors 3 can be independently rotated and switched in the direction close to the dipole box 11 or the direction away from the dipole box 11 by being pried, forming the inward folding state as shown in Figure 6 or the outward unfolding state as shown in Figure 2 .
[0038] For the convenience of explanation and description, in the embodiment, the inward folding state refers to that the first directors 2 and the second directors 3 are respectively pried and rotated 90° in the direction close to the dipole box 11. The outward unfolding state refers to that the first directors 2 and the second directors 3 are respectively pried and rotated 90° in the direction away from the dipole box 11.
[0039] As Figure 5 shown in FIG. 6, in the embodiment, each group of the first platform 5 and the second platform 6 has a height difference in the height direction so that the corresponding first director 2 and the corresponding second director 3 are arranged in a staggered manner in the height direction, and the corresponding first director 2 and the corresponding second director 3 do not interfere with each other during simultaneous or non-simultaneous steering.
[0040] As Figure 6 shown in FIG. 5, in the embodiment, when the rotating lifting folding antenna is packaged, each first director 2 and each second director 3 can be switched to the inward folding state, so that the required area during packaging is reduced, and the transportation cost is low. Figure 1 As shown in FIG. 6, when the user uses the rotating lifting folding antenna, each first director 2 and each second director 3 can be switched to the outward unfolding state, so that the directors can receive and send signals in a specific direction.
[0041] Figure 1 As shown in FIG. 2, in the embodiment, the vibrator base 1 further comprises at least two fixing members 14, and the two ends of the vibrator box 11 are fixedly connected with the first director base 12 and the second director base 13 through the fixing members 14.

When the first director 2 or the second director 3 is independently rotated and switched between the preset inner folding state or the outer unfolding state, the first director 2 or the second director 3 can cross the limiting block 16. When the first director 2 or the second director 3 forms the outer unfolding state, the first director 2 or the second director 3 is stopped and contacted with the limiting block 16. Through the stopping and contacting mode, after the user uses the rotating and lifting folding antenna to unfold outward, the first director 2 or the second director 3 can be fastened and will not be loosened, which will not affect the use effect of the antenna.
[0044] In the embodiment, since the director of the rotating and lifting folding antenna can be independently rotated and switched between the inner folding state or the outer unfolding state, when the antenna product is shipped, the volume of the package does not need to be reduced by disassembling the director, and when the user uses it, the user does not need to install it by using additional installation tools, which is labor-saving and low in transportation cost.
