Description

Technical Field

[0001] This utility model relates to the field of broadcast transmitting antenna technology, and in particular to an installation structure for a broadcast transmitting antenna. Background Technology

[0002] The broadcast transmitting antenna is a crucial component of a broadcasting system. It is responsible for converting radio frequency signals carrying audio, video, or other information into electromagnetic waves and propagating them through the air so that distant receiving devices can receive the broadcast content clearly.

[0003] Existing broadcast transmitting antennas are typically fixed to the antenna bracket using multiple sets of bolts. When installing and removing the antenna, it is necessary to tighten or loosen multiple sets of bolts one by one. This process is very time-consuming and laborious, thus affecting the efficiency of antenna installation. To address this, we propose an installation structure for broadcast transmitting antennas. Utility Model Content

[0004] The main objective of this invention is to provide an installation structure for a broadcast transmitting antenna, which can effectively solve the problems in the background art.

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

[0006] An installation structure for a broadcast transmitting antenna includes a mounting plate with a cavity inside. A movable plate is slidably connected to the inner wall of the mounting plate. Two sets of clamping rods are fixedly installed on one side of the movable plate, and the tail ends of the clamping rods are slidably connected to the inner wall of the mounting plate. A first spring is fixedly installed on the other side of the movable plate, and the tail end of the first spring is fixedly connected to the inner wall of the mounting plate. A rotating shaft is rotatably connected to the inner wall of the mounting plate. An abutment block is fixedly installed on the outer surface of the rotating shaft, and the outer surface of the abutment block is arc-shaped. An antenna body is fixedly installed on the outer surface of the mounting plate, and an antenna bracket is movably connected to the outer surface of the mounting plate.

[0007] Preferably, a pawl is rotatably connected to the outer surface of the mounting plate, and a support plate is fixedly mounted on the outer surface of the mounting plate.

[0008] Preferably, a second spring is fixedly installed at the bottom of the support plate, and the tail end of the second spring is fixedly connected to the outer surface of the front end of the pawl.

[0009] Preferably, a ratchet is fixedly installed at the front end of the rotating shaft, and the ratchet is located on the outside of the mounting plate, and the front end of the pawl is movably connected to the notch of the ratchet.

[0010] Preferably, a knob is fixedly installed at the front end of the rotating shaft, and the knob is located on the outside of the mounting plate.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] In this invention, by setting an abutment block and a movable plate, when the abutment block squeezes the movable plate, the distance between the front end of the clamping rod and the mounting plate is reduced. When the outer surface of the mounting plate and the front end of the clamping rod are tightly attached to the surface of the antenna support rod, the antenna support rod can be clamped, thereby achieving the purpose of installing the antenna body on the antenna support. The operation is simple and quick, effectively improving the installation efficiency. By setting a first spring, when the first spring is squeezed, the reaction force generated by it can ensure that the movable plate and the abutment block are in continuous contact. When the pawl is disengaged from the ratchet, the first spring can drive the movable plate to quickly rebound, so that the clamping is quickly released. The operation is simple and effortless.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Example 1:

[0021] like Figure 1-5As shown, an installation structure for a broadcast transmitting antenna includes a mounting plate 1 with an internal cavity. A movable plate 2 is slidably connected to the inner wall of the mounting plate 1. Two sets of clamping rods 3 are fixedly installed on one side of the movable plate 2, and the tail ends of the clamping rods 3 are slidably connected to the inner wall of the mounting plate 1. When the movable plate 2 moves, it will drive the clamping rods 3 to move synchronously. A first spring 4 is fixedly installed on the other side of the movable plate 2, and the tail end of the first spring 4 is fixedly connected to the inner wall of the mounting plate 1. When the movable plate 2 moves closer to the first spring 4, it will squeeze the first spring 4, and at the same time, the first spring 4 has a reaction force on the movable plate 2. A rotating shaft 5 is rotatably connected to the inner wall of the mounting plate 1, and an abutment block 6 is fixedly installed on the outer surface of the rotating shaft 5. The outer surface is arc-shaped. When the rotating shaft 5 rotates, it will drive the abutment block 6 to make a circular motion around the rotating shaft 5. The initial gap between the movable plate 2 and the rotating shaft 5 is smaller than the width of the abutment block 6. When the abutment block 6 contacts the movable plate 2, it will continuously squeeze the movable plate 2 towards the first spring 4, thereby causing the movable plate 2 to drive the clamping rod 3 to slide continuously into the mounting plate 1. The distance between the front end of the clamping rod 3 and the mounting plate 1 gradually decreases until the antenna bracket 13 is clamped, thereby achieving the purpose of installing the antenna body 12 on the antenna bracket 13. The operation is simple and quick, effectively improving the efficiency of antenna installation. The antenna body 12 is fixedly installed on the outer surface of the mounting plate 1, and the antenna bracket 13 is movably connected to the outer surface of the mounting plate 1.

[0022] A pawl 7 is rotatably connected to the outer surface of the mounting plate 1, and a support plate 8 is fixedly mounted on the outer surface of the mounting plate 1. A second spring 9 is fixedly mounted on the bottom of the support plate 8, and the tail end of the second spring 9 is fixedly connected to the outer surface of the front end of the pawl 7. A ratchet 10 is fixedly mounted on the front end of the rotating shaft 5, and the ratchet 10 is located on the outside of the mounting plate 1. The front end of the pawl 7 is movably connected to the notch of the ratchet 10. The pawl 7 is connected to the second spring 9 through the support plate 8. By setting the second spring 9, the front end of the pawl 7 can fit tightly against the notch of the ratchet 10. By setting the pawl 7, when the front end of the pawl 7 is engaged in the notch of the ratchet 10, the ratchet 10 can only rotate in one direction, thereby preventing the rotating shaft 5 from reversing and ensuring the stability of the clamping. A knob 11 is fixedly mounted on the front end of the rotating shaft 5, and the knob 11 is located on the outside of the mounting plate 1.

[0023] It should be noted that this utility model is an installation structure for a broadcast transmitting antenna. In use, the antenna body 12 is fitted onto the antenna bracket 13, so that the rod of the antenna bracket 13 is located between two sets of antenna brackets 13. Then, the knob 11 is rotated, causing the rotating shaft 5 to drive the abutment block 6 to rotate. When the abutment block 6 contacts the movable plate 2, it will continuously squeeze the movable plate 2, causing the movable plate 2 to move along the inner wall of the mounting plate 1 towards the first spring 4 and squeeze the first spring 4. Then, under the action of the movable plate 2, the distance between the front end of the clamping rod 3 and the mounting plate 1 gradually decreases until the rod of the clamping rod 3 is tightly clamped, thereby achieving the goal of clamping the antenna body 12. The purpose of fixing the antenna to the antenna bracket 13 can be achieved simply by turning the knob 11. The operation is simple and effortless. When disassembling the antenna body 12, the front end of the pawl 7 is pushed upward so that the front end of the pawl 7 disengages from the notch of the ratchet 10. At this time, the restriction of the ratchet 10 is released, the potential energy stored in the first spring 4 is released, the first spring 4 drives the movable plate 2 to rebound, and pushes the abutment block 6 and the rotating shaft 5 in the opposite direction. Under the action of the movable plate 2, the clamping rod 3 slides in the opposite direction along the inner wall of the mounting plate 1, thereby releasing the clamping of the antenna bracket 13 rod. Then the antenna body 12 can be removed. The operation is simple and quick, saving time and effort.
