Abstract
Description
Technical Field
[0001] This utility model relates to the field of antenna installation equipment technology, and in particular to a clutch mechanism for antenna adjustment. Background Technology
[0002] Currently, most antenna adjustment devices on the market use gearboxes for both vertical and horizontal rotation. This structure has the problem of asynchronous vertical rotation, which means the antenna cannot rotate synchronously, making the mechanism prone to damage and resulting in a short service life. In severe cases, it can even lead to the antenna becoming twisted and unusable. Utility Model Content
[0003] In view of the above situation, it is necessary to propose a clutch mechanism for antenna adjustment that facilitates synchronous rotation of the antenna.
[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a clutch mechanism for antenna adjustment, comprising:
[0005] Linear movement mechanism;
[0006] Brake pad, including an arc arm and an extension arm connected to the middle of the arc arm, the concave surface of the arc arm having a first friction surface;
[0007] A rotating block has a second friction surface on its outer peripheral wall. The linear movement mechanism drives the brake pad to contact or move away from the rotating block, so that the first friction surface contacts or moves away from the second friction surface.
[0008] Furthermore, the linear movement mechanism includes a motor, a cam, and a movable frame. The movable frame has a receiving groove, and the cam is disposed in the receiving groove and intermittently abuts against the front and rear walls of the movable frame under the drive of the motor, thereby causing the movable frame to move linearly. The movable frame is connected to the extension arm.
[0009] Furthermore, it also includes a mounting bracket, which comprises a connected horizontal mounting plate and a vertical mounting plate, the motor being mounted on the horizontal mounting plate, and the rotating block being rotatably mounted on the horizontal mounting plate.
[0010] Furthermore, it also includes a protective box, which is fixedly connected to the horizontal mounting plate. The linear movement mechanism is disposed inside the protective box. The protective box has a shaft hole for the output shaft of the motor to extend into and a shaft groove for assembling the end of the output shaft. The protective box also has a guide hole for the extension arm to extend into.
[0011] Furthermore, it also includes a pole-holding mechanism, which includes a first pole-holding frame, a second pole-holding frame, and a spacing adjustment connector. The first pole-holding frame is fixedly connected to the vertical mounting plate, and the first pole-holding frame is adjustablely connected to the second pole-holding frame through the spacing adjustment connector.
[0012] Furthermore, both the first pole support frame and the second pole support frame include a first clamping plate, a second clamping plate, and several connecting plates. The first clamping plate and the second clamping plate are spaced apart vertically and connected by the connecting plates. The first pole support frame and the second pole support frame have pole support slots at their facing ends.
[0013] Furthermore, the first clamping plate and the second clamping plate at the rod holder slot have several serrations.
[0014] Furthermore, both the first friction surface and the second friction surface are toothed surfaces.
[0015] Furthermore, it also includes an antenna box connecting frame, which is fixedly connected to the rotating block.
[0016] Furthermore, the antenna box connecting frame includes a horizontal connecting frame, a folding connecting frame, and a tension adjustment connector. The horizontal connecting frame and the folding connecting frame are hinged together by the tension adjustment connector, and the horizontal connecting frame is fixedly connected to the rotating block.
[0017] The beneficial effects of this utility model are as follows: By replacing one of the antenna up-and-down adjustment mechanisms with the mechanism of this utility model, i.e., having only one gearbox, the antenna up-and-down adjustment mechanism can rotate synchronously up and down. The linear movement mechanism drives the brake pad to move linearly back and forth, causing the first friction surface of the brake pad to contact or move away from the second friction surface of the rotating block, thereby locking or allowing rotation, realizing the clutch function. This facilitates the angle adjustment of the antenna box and ensures the stability after adjustment. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description of a clutch mechanism for antenna adjustment, in conjunction with the accompanying drawings and embodiments, is provided. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the scope of the utility model.
[0030] Please refer to Figures 1-3 A clutch mechanism for antenna adjustment, comprising:
[0031] Linear moving mechanism 100;
[0032] Brake pad 200 includes an arc arm 210 and an extension arm 220 connected to the middle of the arc arm 210, the concave surface of the arc arm 210 having a first friction surface 211;
[0033] The rotating block 300 has a second friction surface 310 on its outer peripheral wall. The linear movement mechanism 100 drives the brake pad 200 to contact or move away from the rotating block 300, so that the first friction surface 211 contacts or moves away from the second friction surface 310.
[0034] The mechanism of this invention replaces one of the antenna up-and-down adjustment mechanisms, meaning there is only one gearbox, enabling the antenna up-and-down adjustment mechanism to rotate synchronously up and down. The linear movement mechanism 100 drives the brake pad 200 to move linearly back and forth, causing the first friction surface 211 of the brake pad 200 to contact or move away from the second friction surface 310 of the rotating block 300, thereby locking or enabling rotation, realizing the clutch function. This facilitates the angle adjustment of the antenna box and ensures the stability after adjustment.
[0035] Please refer to Figure 2 and Figure 3 The linear movement mechanism includes a motor 110, a cam 120, and a moving frame 130. The moving frame 130 has a receiving groove 131. The cam 120 is disposed in the receiving groove 131 and intermittently abuts against the front and rear walls of the moving frame 130 under the drive of the motor 110, thereby enabling the moving frame 130 to move linearly. The moving frame 130 is connected to the extension arm 220. The use of the cam 120 mechanism allows the motor 110 to be positioned vertically, thus avoiding excessive spacing between the antenna box and the pole, reducing the vertical distance between the antenna and the pole, and improving wind load resistance. Furthermore, the clutch can share the lateral wind load on the gearbox, extending the service life of the mechanism.
[0036] Please refer to Figures 1-3 It also includes a mounting bracket 400, which comprises a connected horizontal mounting plate 410 and a vertical mounting plate 420. The motor 110 is mounted on the horizontal mounting plate 410, and the rotating block 300 is rotatably mounted on the horizontal mounting plate 410. The horizontal mounting plate 410 and the vertical mounting plate 420 facilitate the assembly of the motor 110 and the rotating block 300, and also facilitate stable connection with other components such as the lever mechanism 600.
[0037] Please refer to Figure 1 It also includes a protective box 500, which is fixedly connected to the horizontal mounting plate 410. The linear motion mechanism 100 is disposed inside the protective box 500. The protective box 500 has a shaft hole for the output shaft of the power supply motor 110 to extend into and a shaft groove for assembling the end of the output shaft. The protective box 500 also has a guide hole for the extension arm 220 to extend into. The protective box 500 is provided to prevent the linear motion mechanism 100 from being disturbed during movement, and the protective box 500 also provides a guiding function.
[0038] Please refer to Figures 1-3It also includes a pole-mounting mechanism 600, which comprises a first pole-mounting frame 610, a second pole-mounting frame 620, and a spacing adjustment connector 630. The first pole-mounting frame 610 is fixedly connected to the vertical mounting plate 420, and the first pole-mounting frame 610 is adjustablely connected to the second pole-mounting frame 620 via the spacing adjustment connector 630. The adjustable-spacing pole-mounting mechanism 600 can accommodate poles of different diameters. Simply put, the spacing adjustment connector 630 can consist of a screw and a nut.
[0039] Please refer to Figures 1-3 Both the first pole support frame 610 and the second pole support frame 620 include a first clamping plate 641, a second clamping plate 642, and several connecting plates 643. The first clamping plate 641 and the second clamping plate 642 are spaced vertically and connected by the connecting plates 643. The facing ends of the first pole support frame 610 and the second pole support frame 620 have pole support slots 651. Using the first clamping plate 641 and the second clamping plate 642 to clamp the upright at intervals improves the stability of the connection with the upright.
[0040] Please refer to Figures 1-3 The first clamping plate 641 and the second clamping plate 642 at the pole clamping slot 651 have several serrations 652. The serrations 652 ensure a stable connection with the pole.
[0041] Please refer to Figures 1-3 Both the first friction surface 211 and the second friction surface 310 are toothed surfaces. The teeth on the toothed surfaces are generally long and thin, and using toothed surfaces can better achieve locking.
[0042] Please refer to Figure 1 and Figure 2 It also includes an antenna box connector 700, which is fixedly connected to the rotating block 300. Simply put, the antenna box connector 700 is screwed to the end face of the rotating block 300.
[0043] Please refer to Figure 1 and Figure 2 The antenna box connecting frame 700 includes a horizontal connecting frame 710, a folding connecting frame 720, and a tension adjustment connector 730. The horizontal connecting frame 710 and the folding connecting frame 720 are hinged together by the tension adjustment connector 730, and the horizontal connecting frame 710 is fixedly connected to the rotating block 300. Generally, the tension adjustment connector 730 uses a screw and a nut.
[0044] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.
[0045] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.
[0046] In summary, this utility model provides a clutch mechanism for antenna adjustment. By replacing one component of the antenna up-and-down adjustment mechanism with this mechanism, only one gearbox is needed, enabling the antenna up-and-down adjustment mechanism to rotate synchronously up and down. The linear motion mechanism drives the brake pad to move linearly back and forth, causing the first friction surface of the brake pad to contact or move away from the second friction surface of the rotating block, thereby locking or allowing rotation, achieving the clutch function. This facilitates the angle adjustment of the antenna box and ensures stability after adjustment.
