Description

Technical Field

[0001] This application relates to the field of antenna technology, and particularly to a repeater panel antenna. Background Art

[0002] A repeater panel antenna, also known as a planar antenna or a microstrip antenna, is a type of antenna that uses the electromagnetic field coupling between a conductor iron sheet and a ground plane to radiate and receive radio waves. The rectangular panel antenna is the most common. The working principle of the repeater panel antenna is based on the propagation and radiation of electromagnetic waves. When a radio frequency signal reaches the radiation patch through a feeder, an electromagnetic field will be excited between the patch and the ground plane, and then electromagnetic waves will be radiated into outer space. When receiving, the panel antenna captures the electromagnetic waves in space, converts them into electrical signals through the principle of electromagnetic induction, and then transmits them to the receiving device through the feeder.

[0003] The existing repeater panel antenna is fixed on a mast by a clamping block. The bottom end of the antenna is rotatably connected to the clamping block below, and the upper end of the antenna is connected to the clamping block above through a support rod. By changing the position of the upper clamping block, the downward inclination support angle of the antenna is changed, and then the signal receiving angle of the antenna is changed. However, the existing installation structures are all fixed by bolts. When adjusting, it is necessary to loosen the upper clamping block to adjust the downward inclination angle of the antenna, which is cumbersome to operate and not convenient for quickly adjusting the angle. The signal receiving state of the antenna will also be affected to a certain extent in windy weather.

[0004] In view of this, this application proposes a repeater panel antenna. Summary of the Invention

[0036] Generally, the components of the embodiments of the present application described and shown in the accompanying drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application claimed, but merely represents the selected embodiments of the present application.

[0037] Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present application.

[0038] Embodiment

[0039] As Figures 1 - 6 shown, a repeater panel antenna proposed by the present application includes a supporting pole 1 and a fixing member 2 installed on its side wall. The fixing member 2 is detachably connected to the supporting pole 1. One side of the fixing member 2 is provided with an antenna 3 through a supporting block 6. The supporting block 6 is rotatably connected to the fixing member 2, and the other end of the supporting block 6 is fixedly connected to the antenna 3.

[0040] It further includes a lifting control member 4 provided on the side wall of the supporting pole 1. The lifting control member 4 is supported and connected to the antenna 3 through a support shaft 8; by adjusting the supporting height on one side of the support shaft 8 through the lifting control member 4, the supporting angle between the support shaft 8 and the antenna 3 is changed, and finally the signal receiving angle of the antenna 3 is changed.

[0041] Among them, the lifting control member 4 includes a control screw 41 and a second T-shaped frame 42 slidably connected to the side wall of the supporting boom 1. The second T-shaped frame 42 is sleeved on the side wall of the control screw 41 in a transmission manner, and the height position of the second T-shaped frame 42 is adjusted by controlling the control screw 41.

[0042] One side of the second T-shaped frame 42 is provided with a locking angle mechanism 9 for locking the support shaft 8. After the lifting control member 4 adjusts the angle, the angle is locked by the locking angle mechanism 9.

[0043] Specifically, a first groove is formed at one end of the second T-shaped frame 42. One end of the support shaft 8 is connected to the first groove through a second connecting shaft 11. The second connecting shaft 11 is fixedly connected in the groove. One end of the support shaft 8 is rotatably connected to the second connecting shaft 11. The upper side wall of the upper end of the antenna 3 is connected with a U-shaped connecting block 5. The other end of the support shaft 8 is rotatably connected to the U-shaped connecting block 5 through a first connecting shaft 10.

[0044] Further, the locking angle mechanism 9 includes a U-shaped convex block 97 fixedly connected to the first groove at one end of the second T-shaped frame 42. A bidirectional lead screw 92 is rotatably connected through the U-shaped convex block 97. Locking angle pieces 91 are movably sleeved at both ends of the second connecting shaft 11. The two locking angle pieces 91 are respectively sleeved on both ends of the bidirectional lead screw 92 in a transmission manner. The two locking angle pieces 91 are respectively located on both sides of the support shaft 8. After the angle of the antenna 3 is adjusted, by adjusting the rotation direction of the bidirectional lead screw 92, the two locking angle pieces 91 respectively abut against the two side walls of the support shaft 8, thereby completing the fixation of the bottom of the support shaft 8 (making the bottom end of the support shaft 8 fixed relative to the second connecting shaft 11). A second groove 98 is formed at one end of the second T-shaped frame 42. One end of the bidirectional lead screw 92 extends into the second groove 98, and a gear 93 located inside the second groove 98 is fixedly sleeved at one end of the bidirectional lead screw 92. A rack 94 is slidably connected through the second T-shaped frame 42. The rack 94 is in meshing transmission with the gear 93. Limiting blocks 99 are fixedly connected to both the upper and lower ends of the rack 94. A sliding rod 95 is connected between the two limiting blocks 99. The sliding rod 95 penetrates through the end of the second T-shaped frame 42 and is slidably connected to the second T-shaped frame 42. The sliding rod 95 plays a guiding role for the rack 94, and the upper and lower two limiting blocks 99 play a limiting role for the rack 94. By driving the bidirectional lead screw 92 to rotate forward or backward through the meshing transmission of the rack 94 and the gear 93, the number of turns of the bidirectional lead screw 92 can be accurately controlled. When the limiting plate at the upper end of the rack 94 contacts the upper end of the second T-shaped frame 42, the two locking angle pieces 91 just abut against the two side walls of the support shaft 8.

[0045] In this embodiment, the fixing member 2 includes a first clamping plate 22 and a second clamping plate 23. Both ends of the first clamping plate 22 and the second clamping plate 23 are connected through bolts 24. One end of each of the two bolts 24 is threadedly connected with a nut 25. One end of the first clamping plate 22 is connected with a first T-shaped frame 21. One end of the first T-shaped frame 21 is rotatably connected with a support block 6. The support block 6 is fixedly connected with the antenna 3. The control screw rod 41 is rotatably connected to the upper end of the first T-shaped frame 21. A support bearing is embedded in the upper end of the first T-shaped frame 21. The bottom end of the control screw rod 41 is fixedly connected with the inner ring of the support bearing.

[0046] Furthermore, the lifting control member 4 further includes a guide rod 43 fixedly connected to the upper end of the first T-shaped frame 21. The guide rod 43 is slidably connected with the U-shaped convex block 97. One end of each of the two locking angle pieces 91 close to each other is fixedly connected with a convex block 96. The two convex blocks 96 are respectively located on both sides of the guide rod 43. When the two locking angle pieces 91 respectively abut against the two side walls of the support shaft 8, the two convex blocks 96 respectively abut against the two side walls of the guide rod 43, further completing the vertical positioning of the second T-shaped frame 42, enabling the antenna to have a stable support state after angle adjustment, and making the second T-shaped frame 42 have higher stability under vertical support.

[0047] Among them, an auxiliary positioning member 7 is jointly arranged on the first clamping plate 22, the second clamping plate 23 and the support pole 1, which is used to complete the role of auxiliary support during installation. The installation difficulty is reduced, and one person can quickly complete the installation. The auxiliary positioning member 7 includes a slot 71 opened on the side wall of the support pole 1. A magnet block 72 is fixedly embedded in the middle of the slot 71. One end of the first clamping plate 22 and the second clamping plate 23 close to each other are respectively fixedly connected with a second iron plug rod 74 and a first iron plug rod 73. The second iron plug rod 74 and the first iron plug rod 73 are respectively inserted on both sides of the magnet block 72, and both the first iron plug rod 73 and the second iron plug rod 74 can be attracted by the magnet block 72. Arc-shaped grooves are respectively opened on the surfaces of the first clamping plate 22 and the second clamping plate 23 close to each other, and the arc-shaped grooves match the outer arc surface of the support pole 1. When fixing, the contact area between the first clamping plate 22, the second clamping plate 23 and the support pole 1 is increased, thereby improving the stability.

[0048] The working principle of this embodiment is as follows: Before installing the antenna 3, first fix the support pole 1 at a designated position (the installation structure of the support pole 1 is an existing installation structure, and the specific structure is not shown in the figure. Just keep the support pole 1 vertical during installation). Then, sleeve the second clamp 23, the first clamp 22, and the second T-shaped frame 42 on the side wall of the support pole 1 (where the first clamp 22 and the second clamp 23 are supported and formed by two bolts 24). Then, insert the second iron rod 74 and the first iron rod 73 on the inner walls of the first clamp 22 and the second clamp 23 into both sides of the slot 71 respectively (the insertion action can be completed by pushing the first clamp 22 and the second clamp 23). Then, tighten the two nuts 25, and the installation of the antenna 3 is completed (when the installation is completed, the two locking angle pieces 91 are respectively close to both side walls of the support shaft 8).

[0049] When the direct angle of the antenna 3 needs to be adjusted, first push the rack 94 upwards. At this time, the rack 94 meshes with the gear 93 and drives the rotation of the bidirectional lead screw 92. The rotation of the bidirectional lead screw 92 drives the two locking angle pieces 91 to move away from each other, making the locking angle pieces 91 away from the side wall of the support shaft 8. At the same time, the two bumps 96 also move away from the side wall of the guide rod 43. Next, rotate the control screw 41 forward or backward to drive the second T-shaped frame 42 to move up or down, thereby adjusting the downward inclination support angle of the support shaft 8 for the antenna 3. The downward inclination angle refers to the inclination angle of the antenna 3 relative to the horizontal plane. By adjusting the downward inclination angle, the signal coverage of the antenna can be optimized. When the antenna 3 is adjusted to the appropriate angle, stop rotating the control screw 41. Finally, press the rack 94 downwards, so that the rack 94 meshes with the gear 93 in the reverse direction and drives the rotation of the bidirectional lead screw 92, making the two locking angle pieces 91 move closer to each other and respectively abut against both side walls of the support shaft 8, making the bottom end of the support shaft 8 relatively fixed to the second connecting shaft 11, and completing the fixed support state after the angle of the antenna 3 is adjusted; at the same time, the two bumps 96 respectively abut against both side walls of the guide rod 43, further completing the vertical positioning of the second T-shaped frame 42, so that the antenna has a stable support state after the angle is adjusted, thereby enabling the antenna to have a stable signal reception effect, and even in strong wind weather, the antenna 3 will not shake and can maintain an accurate signal reception angle.

Based on the technical solution of the present application and the relevant revelations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments; the above specific embodiments are only explanations of the present application and do not limit the present application.
