A folding antenna support

Abstract

This utility model discloses a foldable broadcast antenna bracket, relating to the field of antenna bracket technology. It includes a fixed rod, and a reinforcement component between the fixed rod and a movable rod for enhancing the stability of their connection. The reinforcement component contains a pair of cylinders and a first bidirectional lead screw, forming a stable triangular shape with the fixed rod and movable rod. When the first bidirectional lead screw is rotated, the pair of cylinders slowly expand outwards, gradually supporting the fixed rod and movable rod until a predetermined angle is reached. Using the cylinders and the first bidirectional lead screw as a whole, forming a stable triangular shape with the fixed rod and movable rod, this solution provides a wider reinforcement range and greater stability compared to fixing only at the hinge. Even with prolonged use, it will not loosen, meeting usage requirements.

Description

Technical Field

[0001] This utility model relates to the field of antenna support technology, and in particular to a foldable broadcast antenna support. Background Technology

[0002] Broadcasting is a medium that transmits sound and image programs to a wide area via radio waves or wires. Broadcasting that only transmits sound is called audio broadcasting; broadcasting that transmits both sound and images is called television broadcasting. In a narrow sense, broadcasting uses radio waves and wires to transmit content solely through sound. In a broader sense, broadcasting includes what we commonly consider audio-only broadcasting as well as television broadcasting, which often requires a broadcast antenna bracket.

[0003] To facilitate adjustment of the signal reception angle of broadcast antennas, antenna brackets are often designed to be foldable. However, foldable antenna brackets are often only reinforced at the hinge points, and the overall sturdiness of the bracket is generally poor, making it prone to loosening and unsuitable for long-term use. Utility Model Content

[0004] The purpose of this utility model is to provide a foldable broadcast antenna bracket in order to solve the problem of general sturdiness.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A foldable broadcast antenna bracket includes a fixed rod, a movable rod rotatably mounted on the upper end of the fixed rod, a reinforcement component for strengthening the connection stability between the fixed rod and the movable rod is provided between the fixed rod and the movable rod, the reinforcement component is provided with a pair of cylinders and a first bidirectional lead screw, the cylinders and the first bidirectional lead screw form a stable triangular shape with the fixed rod and the movable rod, and the antenna body is provided at the other end of the movable rod.

[0006] As a further description of the above technical solution: both the fixed rod and the movable rod are provided with mounting grooves and movable grooves.

[0007] As a further description of the above technical solution: the reinforcement component includes a first slider rotatably mounted on the end of the cylinder and a dust cover fixedly mounted on the cylinder. The first bidirectional screw is threadedly connected to the cylinder. The first slider is movably connected to the movable groove and is adapted to the mounting groove. The other end of the dust cover is rotatably connected to the first bidirectional screw. The cylinder is provided with a limiting component to prevent the first slider from sliding.

[0008] As a further description of the above technical solution: the limiting component includes a second bidirectional lead screw threaded between the round rod and the connecting rod, a second slider movably installed in the movable groove, and a dust cover fixedly installed on the round rod and the connecting rod. The round rod is fixedly installed on the cylinder, the connecting rod is rotatably installed on the second slider, and the other end of the dust cover is rotatably connected to the second bidirectional lead screw.

[0009] As a further description of the above technical solution: a rubber pad is fixedly installed on the side of the second slider that contacts the movable groove.

[0010] As a further description of the above technical solution: both the first bidirectional lead screw and the second bidirectional lead screw have a notch in the middle.

[0011] As a further description of the above technical solution: a disc is fixedly installed at the lower end of the fixing rod, and a fixing plate is rotatably installed on the lower end face of the disc.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: 1. Rotate the first bidirectional lead screw, and a pair of cylinders slowly expand outward. The pair of cylinders slowly support the fixed rod and the movable rod until the predetermined angle is reached. Using the cylinders and the first bidirectional lead screw as a whole, a stable triangular shape is formed between the fixed rod and the movable rod. Compared with the method of fixing only at the hinge, the reinforcement range of this technical solution is larger and more stable. Even if used directly for a long time, there will be no loosening, which meets the usage requirements. 2. The rubber pad increases the friction between the side of the second slider and the inner wall of the movable groove, preventing the second slider from sliding relative to the movable groove when the bracket is subjected to external force, which would cause the bracket to loosen over time.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example: This example provides a foldable broadcast antenna bracket, see [link / reference]. Figure 1 - Figure 4 Specifically, it includes a fixed rod 1, a movable rod 11 rotatably mounted on the upper end of the fixed rod 1, a reinforcement component for strengthening the connection stability between the fixed rod 1 and the movable rod 11, a pair of cylinders 2 and a first bidirectional lead screw 21 are provided in the reinforcement component, the cylinders 2 and the first bidirectional lead screw 21 form a stable triangular shape with the fixed rod 1 and the movable rod 11, and an antenna body 12 is provided at the other end of the movable rod 11; Rotating the first bidirectional lead screw 21 causes a pair of cylinders 2 to slowly expand outwards, gradually supporting the fixed rod 1 and the movable rod 11 until a predetermined angle is reached. Using the cylinders 2 and the first bidirectional lead screw 21 as a whole, a stable triangular shape is formed between them, the fixed rod 1 and the movable rod 11. Compared with fixing only at the hinge, this technical solution has a larger reinforcement range and is more stable. Even with long-term use, it will not loosen, thus meeting the usage requirements. Both the fixed rod 1 and the movable rod 11 are provided with mounting grooves 3 and movable grooves 31. The reinforcement component includes a first slider 22 rotatably mounted on the end of the cylinder 2 and a dust cover 23 fixedly mounted on the cylinder 2. The first bidirectional screw 21 is threadedly connected to the cylinder 2, the first slider 22 is movably connected to the movable groove 31, and the first slider 22 is adapted to the mounting groove 3. The other end of the dust cover 23 is rotatably connected to the first bidirectional screw 21. The cylinder 2 is provided with a limiting component to prevent the first slider 22 from sliding. The limiting component includes a second bidirectional screw 41 threadedly mounted between the round rod 4 and the connecting rod 43, a second slider 42 movably mounted in the movable groove 31, and a dust cover 23 fixedly mounted on the round rod 4 and the connecting rod 43. The round rod 4 is fixedly mounted on the cylinder 2, the connecting rod 43 is rotatably mounted on the second slider 42, and the other end of the dust cover 23 is rotatably connected to the second bidirectional screw 41. First, the fixed rod 1 and the movable rod 11 are opened to a certain angle. The first slider 22 is placed into the mounting groove 3 through the movable groove 31. Then, the first bidirectional screw 21 is rotated, so that the first bidirectional screw 21 continuously extends out of the cylinder 2, and the length between the pair of cylinders 2 and the first bidirectional screw 21 continuously increases. During this process, the cylinder 2 continuously drives the first slider 22 to move along the movable groove 31 until the first slider 22 moves to the end of the movable groove 31 (the end away from the hinge of the fixed rod 1 and the movable rod 11). At this time, the pair of cylinders 2 support the fixed rod 1 and the movable rod 11. Then, the first bidirectional screw 21 is rotated again, so that the first slider 22 continuously expands outward, increasing the opening and closing angle of the fixed rod 1 and the movable rod 11 until the predetermined angle is reached. Rotating the second bidirectional lead screw 41 causes the second slider 42 to move obliquely upwards via the connecting rod 43 until the second slider 42 enters the movable groove 31 and presses against the fixed rod 1 and the movable rod 11. The first slider 22 and the second slider 42 completely lock the connection between the fixed rod 1 and the movable rod 11. Both the first slider 22 and the second slider 42 serve as support points on the fixed rod 1 and the movable rod 11, making the connection between the fixed rod 1 and the movable rod 11 very stable, allowing the bracket to be used for a long time without loosening. A rubber pad 5 is fixedly installed on the side of the second slider 42 that contacts the movable groove 31; The rubber pad 5 increases the friction between the side of the second slider 42 and the inner wall of the movable groove 31, preventing the second slider 42 from sliding relative to the movable groove 31 when the bracket is subjected to external force, which would cause the bracket to loosen over time. Both the first bidirectional lead screw 21 and the second bidirectional lead screw 41 have a notch 6 in the middle; The notch 6 allows operators to use a wrench or other tools to rotate the first double-acting lead screw 21 and the second double-acting lead screw 41, facilitating the installation of the bracket; A disc 7 is fixedly installed at the lower end of the fixed rod 1, and a fixed disc 71 is rotatably installed on the lower end face of the disc 7. The mounting plate 71 can be installed in the area to be installed through the pre-drilled mounting holes on it. The disc 7 can drive the entire bracket to rotate relative to the mounting plate 71, thereby adjusting the orientation of the antenna body 12 to receive signals.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
