Description

Technical Field

[0001] This utility model relates to the field of antenna support technology, specifically to a support for adjusting the angle of a broadcasting antenna. Background Technology

[0002] As a key piece of equipment for broadcast television signal transmission, the installation angle of a broadcast antenna directly determines the signal coverage, transmission stability, and signal quality at the receiving end. Therefore, precise adaptation based on geographical environment and coverage requirements is necessary. Currently, the industry commonly uses manual angle adjustment brackets to adjust the antenna angle. These brackets use mechanical structures such as bolts and gears to fix the angle, which, while meeting basic adjustment needs, has significant limitations in practical operating scenarios.

[0003] Existing manual adjustment brackets lack an effective angle adjustment feedback mechanism, making it impossible for users to obtain the antenna adjustment range in real time. This makes it difficult to accurately position the antenna to the preset angle in one go, easily leading to over- or under-adjustment. Such adjustment deviations require repeated fine-tuning and correction, which not only increases the complexity of operation but also prolongs the time required for antenna installation and subsequent maintenance, significantly reducing work efficiency and failing to meet the broadcasting industry's demand for efficient and precise equipment installation and commissioning. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a bracket for adjusting the angle of a broadcast transmitting antenna.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A cable TV transmitting antenna angle adjustment bracket includes an adjustment base, which is rotatably connected to a mounting base via a rotating shaft. The adjustment base is provided with a hand crank assembly that is pulsatorically connected to the mounting base to drive it to rotate around the rotating shaft. The adjustment base is provided with an arc-shaped angle scale plate concentric with the rotating shaft. The angle scale plate has multiple holes circumferentially opened, and the position of each hole is aligned with the corresponding scale value.

[0007] An arc-shaped plate is detachably mounted on the corresponding insertion hole. A baffle is provided at the center of the top of the arc-shaped plate, and multiple spring pieces are symmetrically arranged on both sides of the baffle at the top of the arc-shaped plate.

[0008] An adjustment frame is provided on the mounting base. The adjustment frame is provided with an indicator plate. The length of the indicator plate is configured such that its rotation path around the rotating shaft passes through a baffle and a spring piece, and the overlap length between the indicator plate and the spring piece satisfies the elastic contraction length of the spring piece.

[0009] When the user operates the adjustment frame to rotate towards the arc-shaped plate using the hand crank component, the multiple spring pieces are sequentially squeezed by the indicator plate to elastically contract and generate continuous resistance feedback until the indicator plate contacts the baffle to limit the maximum rotation angle of the adjustment frame.

[0010] Preferably, the spring is a metal spring, the root of which is fixed to the arc-shaped plate, and the free end extends in the direction of the rotation path of the indicator plate.

[0011] Preferably, the thickness of the spring gradually decreases along its extension direction, and its end forms a sharp corner that contacts the side of the indicator plate.

[0012] Preferably, the baffle extends radially along the arc-shaped plate to form a scale value indicating structure.

[0013] Preferably, the arc-shaped plate is provided with a plurality of insert rods, each insert rod slidingly extending into a corresponding insertion hole, and a screw is provided on the corresponding insert rod, and a nut is threaded on the screw. When the nut is screwed to fit the angle scale plate, the relative position of the angle scale plate and the arc-shaped plate is locked.

[0014] Preferably, the hand crank assembly includes a worm gear, a worm, and a handwheel. The worm gear is fixedly sleeved on the rotating shaft, the worm is rotatably mounted on the adjusting seat and meshes with the worm gear, and the handwheel is fixed on the worm.

[0015] Preferably, the bottom of the adjusting seat is provided with a counterweight seat.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. Through the coordinated operation of the indicator plate, spring, and baffle, a dual guarantee of continuous resistance feedback and mechanical hard limit can be formed during the process of adjusting the antenna angle by the adjustment frame. When the antenna approaches the preset angle, the squeezing action of the spring and the indicator plate will increase the resistance of the handwheel rotation, thereby slowing down the antenna deflection speed. This resistance signal is simultaneously fed back to the user, allowing them to perceive the adjustment progress without constantly staring at the scale. This significantly reduces operator fatigue and effectively avoids the problems of angle overshoot or under-adjustment, greatly improving the ease of operation and adjustment efficiency of the device.

[0018] 2. By coordinating the adjustment base, hand crank assembly, angle scale plate, arc plate, and adjustment frame, the self-locking transmission characteristics of the worm gear are organically combined with the precise positioning design of the multi-interval sockets on the angle scale plate. This achieves high-precision adjustment of the antenna angle and allows for flexible adaptation of the arc plate to different sockets, meeting diverse angle limit requirements and improving usability.

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0026] Example

[0027] like Figures 1-4 As shown, a broadcast antenna angle adjustment bracket includes an adjustment base 1. The bottom of the adjustment base 1 is provided with a counterweight 14. By increasing the weight at the bottom, the overall center of gravity is lowered, improving the overall stability of the antenna after installation and preventing the device from tipping over or shifting due to the antenna's own weight or external forces. The adjustment base 1 is rotatably connected to a mounting base 11 via a rotating shaft. The adjustment base 1 is provided with a hand crank assembly 111 that is drively connected to the mounting base 11 to drive it to rotate around the rotating shaft. The mounting base 11 is the direct mounting carrier of the adjustment bracket 2. Its rotation around the rotating shaft directly drives the antenna to achieve angle adjustment, playing a core role in power transmission.

[0028] The hand-cranked assembly 111 includes a worm gear, a worm, and a handwheel. The worm gear is fixedly mounted on the rotating shaft, the worm is rotatably mounted on the adjusting seat 1 and meshes with the worm gear, and the handwheel is fixed to the worm. As the power drive mechanism for angle adjustment, the handwheel provides the user with an operating end. Rotating the handwheel drives the worm to rotate, and the worm meshes with the worm gear fixed on the rotating shaft, transmitting the rotational motion to the rotating shaft, thereby driving the mounting seat 11 to rotate. The worm gear transmission structure has a self-locking characteristic, which locks the position of the mounting seat 11 after adjustment, preventing it from rotating on its own and ensuring the accuracy and stability of angle adjustment.

[0029] The adjustment base 1 is provided with an arc-shaped angle scale plate 12 concentric with the rotating shaft. Multiple insertion holes 121 are opened along the circumference of the angle scale plate 12, and the position of each insertion hole 121 is aligned with the corresponding scale value. The position of the insertion holes 121 can be set at intervals of 3°, 4° or 5°, etc., which not only provides the arc plate 13 with multiple levels and high precision detachable installation positioning points, but also provides users with intuitive angle reference through the scale value, so that users can accurately control the antenna adjustment angle according to actual needs.

[0030] The arc plate 13 is detachably mounted on the corresponding socket 121. As the core actuator for angle limiting and feedback, the arc plate 13 can be selected to be inserted into the appropriate socket 121 according to the actual adjustment requirements, so as to flexibly set the maximum adjustment angle and adapt to different maximum angle limit requirements.

[0031] A baffle 131 is provided at the center of the top of the arc plate 13, and the baffle 131 extends radially along the arc plate 13 to form a scale value indication structure; on the one hand, it provides users with a clear angle reference mark, and on the other hand, it abuts against the indicator plate 21 when it rotates to this position, directly limiting the maximum rotation angle of the adjustment frame 2 and realizing mechanical limit.

[0032] Multiple springs 132 are symmetrically arranged on both sides of the baffle 131 at the top of the arc plate 13. The springs 132 are metal springs, with their roots fixed to the arc plate 13 and their free ends extending in the direction of the rotation path of the indicator plate 21. The thickness of the springs 132 gradually decreases along its extension direction, and its ends form sharp corners that contact the side of the indicator plate 21. This makes the ends of the springs 132 flexible force-bearing ends, which have better elastic deformation capabilities than structures with equal thickness. They can smoothly contract and reset when in contact with the indicator plate 21. At the same time, the sharp corner design effectively reduces the contact friction area with the indicator plate 21, which not only ensures the sensitivity of the damping feedback, but also reduces component wear and extends service life.

[0033] The arc-shaped plate 13 is provided with multiple insertion rods 133, each insertion rod 133 slidingly extending into a corresponding insertion hole 121, and each insertion rod 133 is provided with a screw 134, with a nut 135 threaded onto the screw 134. When the nut 135 is screwed to fit the angle scale plate 12, the relative position of the angle scale plate 12 and the arc-shaped plate 13 is locked. The insertion rod 133 is inserted into the insertion hole 121 of the angle scale plate 12 to achieve the initial positioning of the arc-shaped plate 13. The threaded engagement between the screw 134 and the nut 135, by screwing the nut 135, makes the arc-shaped plate 13 and the angle scale plate 12 fit tightly together, locking their relative position and preventing the arc-shaped plate 13 from shifting during the adjustment process, thus ensuring the reliability of the limit and feedback functions.

[0034] The adjustment bracket 2, mounted on the mounting base 11, is a direct mounting component for the broadcast antenna. It receives the rotational power of the mounting base 11 and transmits it to the antenna to achieve synchronous angle adjustment. The adjustment bracket 2 is equipped with an indicator plate 21. The length of the indicator plate 21 is configured such that its rotation path around the axis passes through the baffle 131 and the spring piece 132, and the overlap length of the indicator plate 21 and the spring piece 132 meets the elastic contraction length of the spring piece 132. On the one hand, it provides a visual reference for angle adjustment to the user by cooperating with the scale value of the angle scale plate 12; on the other hand, it generates feedback by squeezing the spring piece 132, and at the same time triggers the limiting function of the baffle 131. It is a key component connecting the adjustment action with the feedback and limiting functions.

[0035] When the user controls the adjustment frame 2 to rotate toward the arc plate 13 by the hand crank component 111, multiple spring pieces 132 are squeezed by the indicator plate 21 in sequence to elastically contract and generate continuous resistance feedback until the indicator plate 21 contacts the baffle 131 to limit the maximum rotation angle of the adjustment frame 2.

[0036] In summary, when the user drives the worm gear to rotate via the handwheel of the hand crank assembly 111, the worm gear meshes with the worm wheel fixed to the rotating shaft, causing the mounting base 11 and the adjustment frame 2 to rotate around the rotating shaft toward the arc plate 13. The indicator plate 21 on the adjustment frame 2 rotates synchronously until it sequentially presses multiple spring pieces 132 on both sides of the arc plate 13. The spring pieces 132, with their gradually decreasing thickness along the extension direction and their pointed end design, achieve smooth elastic contraction and generate continuous and sensitive resistance feedback. This feedback is transmitted to the handwheel through the worm gear transmission chain, allowing the user to perceive the adjustment progress without constantly watching the angle scale plate 12, thus enabling timely deceleration until the indicator plate 21 contacts the baffle 131, forming a mechanical hard limit to precisely restrict the maximum rotation angle of the adjustment frame 2. This allows the user to perceive the adjustment progress without constantly watching the scale, significantly reducing operational fatigue and effectively avoiding the problems of angle overshoot or under-adjustment, greatly improving the ease of operation and adjustment efficiency of the device.

[0037] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
