[0002] Radio and television is a modern communication tool that broadcasts audio and video programs to a wide area through radio waves or wires for the purpose of delivering information, publicity and education. Radio and television can be divided into wireless broadcasting and wired broadcasting according to the transmission method. In radio and television projects, antenna brackets are used to provide stable support and fixed foundation to ensure that the antenna can be firmly installed in a specific location, such as a roof, tower or building, so as to ensure that the antenna can transmit and receive signals.

[0003] Radio and television antennas generally need to be installed in high places to ensure that the antennas will not be interfered with during signal transmission and reception. Therefore, the antenna bracket used for antenna installation needs to be carried to a higher building for use. When installing the antenna bracket, if the bracket is disassembled first and then carried to a designated location for installation, although this method is easy to carry, it takes a lot of time to splice the bracket at the installation location. If the bracket is carried as a whole, it will be inconvenient to carry the bracket because the bracket takes up a large space when unfolded. Both methods will cause the bracket to take too long to install, resulting in low installation efficiency of the bracket. Utility Model Content

[0004] The utility model aims to provide a radio and television engineering antenna bracket in order to solve the problem that the existing antenna bracket takes a long time to install, resulting in low bracket installation efficiency.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Reference Figure 1-Figure 8The radio and television engineering antenna bracket provided in this embodiment includes a support tube 1, the bottom of the support tube 1 is hinged with a bottom plate 3 through a base 2, a slide seat 4 that can slide along its height direction is arranged on the outside of the support tube 1, and a connecting frame 5 is fixedly installed on the outer side of the slide seat 4, and a diagonal bracing mechanism 6 that can perform buffering and shock absorption is hinged between the connecting frame 5 and the bottom plate 3, a support rod 7 is sleeved on the top of the support tube 1, and a mounting platform 8 is fixedly installed at the top of the support rod 7 located above the support tube 1.

[0030] In the utility model, when the antenna is installed by using the antenna bracket, the support rod 7 is first retracted in the support tube 1, and then the slide 4 is moved along the support tube 1 to the top thereof, so that the bottom plate 3 and the diagonal support mechanism 6 can be folded like an umbrella rib structure, thereby greatly reducing the space occupied by the bracket and facilitating the carrying of the bracket. After the bracket is carried to the antenna installation position, the slide 4 is moved along the support tube 1 to the bottom thereof, so that the bottom plate 3 and the diagonal support mechanism 6 are opened like an umbrella rib structure, and the antenna is installed and fixed through the mounting platform 8. The bottom of the support tube 1 is connected with fasteners through the bottom plate 3 on the base 2 to fix the bracket, and then the height of the antenna on the mounting platform 8 can be adjusted by the support rod 7.

[0031] Specifically, Figure 1-Figure 4 As shown, a mounting tube 41 is provided on the slide seat 4, a positioning bolt 42 penetrating the slide seat 4 is provided in the mounting tube 41, and a handle 43 is provided on the end of the positioning bolt 42 away from the slide seat 4;

[0032] The support tube 1 is provided with a first positioning hole 12 and a second positioning hole 13 respectively near the bottom and the top thereof, which are matched with the positioning bolts 42 .

[0033] When the bracket is carried, the positioning bolt 42 in the installation tube 41 is screwed into the second positioning hole 13 of the support tube 1. At this time, the slide 4 is located near the top of the support tube 1, and the base plate 3 and the diagonal bracing mechanism 6 are contracted toward the support tube 1. When the bracket needs to be installed and fixed, first use the handle 43 to loosen the positioning bolt 42 in the second positioning hole 13, and then the slide 4 can slide on the support tube 1 and move toward the bottom of the support tube 1, and then the positioning bolt 42 is screwed into the first positioning hole 12. At this time, the slide 4 is fixed near the bottom of the support tube 1, and the base plate 3 and the diagonal bracing mechanism 6 are opened. At this time, the base plate 3 and the support tube 1 are in a vertical state, and then the fastener is connected to the base plate 3 to fix the bracket.

[0034] Specifically, Figure 3 and Figure 4As shown, a slide bar 46 is provided on the inner wall of the slide seat 4, and a slide groove 14 is provided on the outer surface of the support tube 1 to match the slide bar 46. The slide bar 46 and the slide groove 14 can play a role in sliding guide. After the positioning bolt 42 is loosened, the guide rail formed by the slide bar 46 and the slide groove 14 can ensure that the slide seat 4 slides smoothly on the support tube 1, and the slide bar 46 and the slide groove 14 can also be limited. When the slide seat 4 slides on the support tube 1, it can prevent the slide seat 4 and the support tube 1 from rotating, thereby ensuring the stability of the entire support structure.

[0035] It should be noted that the end of the mounting tube 41 away from the slide seat 4 is detachably connected to a protective cover 45 through a threaded joint 44, and the outer surface of the protective cover 45 is provided with anti-slip grooves. The protective cover 45 is covered on the mounting tube 41 through the threaded joint 44, so that after the state adjustment of the bracket is completed, the protective cover 45 is used to isolate the inside of the mounting tube 41 from the outside, so as to prevent the positioning bolts 42 in the mounting tube 41 from being damaged by collision with foreign objects when the bracket is in normal use.

[0036] Specifically, Figure 1 , Figure 2 and Figure 6 As shown, the diagonal support mechanism 6 includes a diagonal support rod 61, a buffer 63 is provided on the diagonal support rod 61 through a connecting groove 62, and a buffer pad 64 is provided inside the connecting groove 62. The diagonal support rod 61 has a buffering effect through the buffer 63 and the buffer pad 64. When the bracket is installing the antenna, the diagonal support rod 61 is used to support the bottom plate 3 and the support tube 1. The buffer 63 and the buffer pad 64 can buffer the vibration force, thereby ensuring the stability of the bracket.

[0037] It should be noted that there are two buffers 63, which are respectively arranged at both ends of the diagonal brace 61. The buffers 63 are arranged at both ends of the diagonal brace 61 to ensure that the diagonal brace 61 can share the load more evenly when subjected to force, thereby improving the bearing capacity of the bracket, reducing local damage caused by stress concentration, improving the overall stability of the bracket, and preventing the bracket from being unbalanced or damaged due to impact in a single direction.

[0038] Specifically, Figure 1 , Figure 6 and Figure 7 As shown, the buffer member 63 includes a connecting rod 631 arranged coaxially therewith, a limiting end 632 is provided at one end of the connecting rod 631 located inside the connecting groove 62, and a connecting seat 633 is provided at the other end of the connecting rod 631, a spring 634 is sleeved on the outside of the connecting rod 631 at a position between the end of the diagonal support rod 61 and the connecting seat 633, a connecting plate 635 is provided on the end of the connecting seat 633 away from the connecting rod 631, and the buffer pad 64 is filled between the limiting end 632 and the inner wall of the connecting groove 62.

[0039] Among them, when the bracket is subjected to vibration force, the two ends of the diagonal support rod 61 are squeezed, and at this time the connecting rod 631 moves toward the diagonal support rod 61, and then the spring 634 is squeezed and deformed. Through the deformation of the spring 634, the energy generated by the vibration can be absorbed, and the buffer pad 64 uses the elasticity and flexibility of its material to absorb the impact force. When the spring 634 recovers, the buffering of the buffer pad 64 can reduce the vibration amplitude of the spring 634, and the two cooperate to perform effective shock absorption and buffering.

[0040] Specifically, Figure 1 and Figure 5 As shown, a fixing bolt 11 is provided on one side of the top of the support tube 1, and a plurality of fixing screw holes 71 are provided on the support rod 7 and are evenly arranged along the height direction thereof. After the antenna is mounted on the mounting platform 8, the fixing bolt 11 is removed from the fixing screw hole 71, and then the support rod 7 can be moved on the support tube 1 to adjust the height of the antenna. The plurality of fixing screw holes 71 can be used to adjust the antenna to different heights. After the antenna height is adjusted, the fixing bolt 11 can be screwed into the fixing screw hole 71 again.

[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
