Description

Technical Field

[0001] The invention relates to the technical field of antenna brackets, and in particular to an antenna bracket that can be quickly installed. Background Art

[0002] With the rapid development of wireless communication technology, antennas, as key components for signal transmission and reception, are becoming increasingly important in terms of installation stability and convenience. In many communication scenarios, whether it is a large base station antenna towering on the top of a mountain or a small micro base station antenna distributed in every corner of a city, reliable brackets are needed to support it.

[0003] However, under the existing technology, the installation of antenna brackets faces many difficult problems, especially in outdoor environments where strong winds frequently occur, which brings great challenges to the installation of antenna brackets. On the one hand, traditional antenna bracket installation methods mostly rely on bolts, nuts and other connectors for fixing. The installation process is cumbersome and complicated, requiring operators to carry and use a variety of tools, such as wrenches, screwdrivers, etc. The convenience of tool operation is greatly reduced, which greatly increases the difficulty and time cost of installation.

[0004] On the other hand, when encountering strong winds, the brackets that have not been completely fixed are very likely to move due to the wind. The lateral force generated by the strong wind will cause the brackets to deviate from the predetermined installation position, making it difficult to ensure the installation accuracy. It may even cause some of the connectors that have been initially installed to loosen or be damaged, forcing the operator to have to readjust the bracket position and tighten the connectors. This repetitive process seriously hinders the rapid progress of the installation work and greatly reduces the installation efficiency. Summary of the invention

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. By setting the pre-tightening part, the initial limit of the antenna bracket body can be achieved. This initial limit can effectively prevent the antenna bracket body from being greatly offset due to wind force in a windy environment, providing a relatively stable foundation for subsequent installation operations, greatly reducing the difficulty of installation, allowing operators to perform subsequent fixing steps more calmly and improving installation efficiency.

[0020] 2. Through the setting of the installation mechanism, not only can the bottom plate and the base be quickly locked to complete the installation of the antenna bracket body, but also in the process of locking the bottom plate and the base, the pressure of the pre-tightening part on the support bar can be further increased, so that the pre-tightening part can fit more closely with the support bar. When the impact of strong winds causes the components to have a slight displacement tendency, the stability of the entire installation structure is ensured, so that the antenna bracket body can still be firmly installed in bad weather.

[0021] 3. When the torsion bar rotates to a horizontal state, the installation mechanism can complete the installation of the antenna bracket body. The torsion bar can be locked by the squeezing mechanism to prevent the torsion bar from rotating autonomously, so that the antenna bracket body can be firmly fixed. In addition, while the torsion bar is locked by the squeezing mechanism, the stabilizing mechanism can be started simultaneously. When the squeezing bar slides outward, a lateral supporting force is applied to the antenna bracket body, thereby enhancing the stabilizing effect of the antenna bracket body from multiple directions and reducing the possibility of strong winds blowing the antenna bracket body from the side. It is like adding a protective barrier to the antenna bracket body, so that it remains stable in a complex wind environment, improves the reliability after installation, and reduces the risk of loosening due to strong winds.

[0022] 4. Through the setting of the clamping mechanism, under the coordinated action of the installation mechanism, the squeezing mechanism and the stabilizing mechanism, pressure can be applied again from the top to ensure that the antenna bracket body is firmly fixed in all directions and at multiple levels. Even under the continuous impact of strong winds, the installation firmness of the antenna bracket body can be guaranteed, thereby improving the stability of the communication system operation.

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0032] Embodiment 1, refer to Figure 1-Figure 7 , a quickly installed antenna bracket, comprising an antenna bracket body 1 for connecting an antenna, a bottom plate 2 being fixed to the bottom of the antenna bracket body 1, a base 3 fixed to the ground being provided below the bottom plate 2, a pre-tightening portion for initially limiting the position of the antenna bracket body 1 being provided in the base 3, and further comprising:

[0033] A mounting mechanism is arranged in the base 3, and the mounting mechanism is used to lock the bottom plate 2 and the base 3;

[0034] The squeezing mechanism is installed on the base 3, and is used to clamp the antenna bracket body 1 and lock the installation mechanism at the same time.

[0035] Furthermore, the pre-tightening portion includes a support bar 41 symmetrically fixed at the bottom of the base plate 2, the support bar 41 slides in the base 3, a mounting plate 42 is symmetrically fixed on the top wall of the base 3, a cross bar 43 is fixed to a side of the mounting plate 42 close to the support bar 41, a movable disk 40 slides on the outer surface of the cross bar 43, a spring 44 is fixed to the side of the movable disk 40 close to the support bar 41, an arc block 45 is fixed to the end of the spring 44 away from the movable disk 40, and a pre-tightening groove 46 matched with the arc block 45 is provided on the support bar 41.

[0036] When using this technical solution, the base 3 is fixed on the ground, and the support bar 41 is inserted from the top of the base 3 to complete the initial positioning between the antenna bracket body 1 and the base 3. This is the existing technology, so it will not be described in detail here.

[0037] At the same time, considering that strong winds may occur during installation, the brackets that have not been completely fixed are very likely to move due to wind force. The lateral force generated by strong winds will cause the brackets to deviate from the predetermined installation position, making it difficult to ensure installation accuracy, and may even cause some of the preliminarily installed connectors to loosen or be damaged, forcing the operator to readjust the bracket position and tighten the connectors. This repetitive process seriously hinders the rapid advancement of the installation work and greatly reduces the installation efficiency. The following improvements are now made:

[0038] When the support bar 41 is inserted into the base plate 2, as the movable plate 40 slides on the outer surface of the cross bar 43, the support bar 41 will exert backward pressure on the arc block 45, squeezing the spring 44 until the arc block 45 is inserted into the pre-tightening groove 46 provided on the support bar 41, thereby preliminarily locking the support bar 41, thereby achieving preliminary positioning of the antenna bracket body 1. This preliminary positioning can effectively prevent the antenna bracket body 1 from being significantly deviated due to wind force in a windy environment, thereby providing a relatively stable foundation for subsequent installation operations, greatly reducing the difficulty of installation, and allowing operators to perform subsequent fixing steps more calmly, thereby improving installation efficiency.

[0039] It should be noted that: when the support bar 41 is not inserted into the base 3, the initial position of the movable disk 40 is close to the mounting plate 42. Since the mounting plate 42 is connected to the bottom plate 2, the supporting force for the movable disk 40 can be increased, so that the arc block 45 can be inserted into the pre-tightening groove 46 by the elastic force of the spring 44, thereby preliminarily fixing the support bar 41.

[0040] Example 2, refer to Figure 1-Figure 7 , a quickly installed antenna bracket, comprising an antenna bracket body 1 for connecting an antenna, a bottom plate 2 being fixed to the bottom of the antenna bracket body 1, a base 3 fixed to the ground being provided below the bottom plate 2, a pre-tightening portion for initially limiting the position of the antenna bracket body 1 being provided in the base 3, and further comprising:

[0041] A mounting mechanism is arranged in the base 3, and the mounting mechanism is used to lock the bottom plate 2 and the base 3;

[0042] The squeezing mechanism is installed on the base 3, and is used to clamp the antenna bracket body 1 and lock the installation mechanism at the same time.

[0043] Furthermore, the mounting mechanism includes a liquid storage cylinder 51 fixed on a side of the mounting plate 42 away from the movable disk 40, a slide rod 52 slides inside the liquid storage cylinder 51, a fixed block 53 is fixed to the end of the slide rod 52 away from the liquid storage cylinder 51, an arc block 54 is fixed on the fixed block 53, a spring 55 is sleeved on the outer surface of the liquid storage cylinder 51, and the two ends of the spring 55 are respectively fixedly connected to the mounting plate 42 and the fixed block 53.

[0044] Furthermore, the mounting mechanism also includes an extrusion rod 56 fixed to the side of the fixed block 53 away from the arc block 2 54, the extrusion rod 56 is slidably connected to the mounting plate 42, a locking rod 57 is fixed to the side of the movable disk 40 close to the arc block 1 45, the locking rod 57 slides in the arc block 1 45 and the support bar 41, a rotating rod 58 is rotated in the base 3 through a bearing, and a cam 59 is fixed to the outer surface of the rotating rod 58.

[0045] Such a technical solution is adopted in view of the fact that the installation process is cumbersome and complicated by locking with bolts in the prior art, and the operator needs to carry and use a variety of tools, such as wrenches, screwdrivers, etc., which greatly reduces the convenience of tool operation and greatly increases the difficulty and time cost of installation. Therefore, an installation mechanism is provided, which can not only quickly lock the bottom plate 2 and the base 3 to complete the installation of the antenna bracket body 1, but also in the process of locking the bottom plate 2 and the base 3, can further increase the pressure of the pre-tightening part on the support bar 41, so that the pre-tightening part can fit more closely with the support bar 41. When the impact of strong winds causes the components to have a slight displacement tendency, the stability of the entire installation structure is ensured, so that the antenna bracket body 1 can still be firmly installed in bad weather.

[0046] Specifically, by rotating the torsion bar 61, the rotating rod 58 and the cam 59 are driven to rotate. When the cam 59 rotates to contact the arc block 2 54, since the slide bar 52 slides in the liquid storage cylinder 51, the arc block 2 54 and the fixed block 53 are driven to move in the direction of the movable disk 40, squeezing the spring 2 55. The fixed block 53 drives the squeezing rod 56 to move together, so that the squeezing rod 56 generates pressure on the movable disk 40, so that the movable disk 40 approaches the outer surface of the cross bar 43 in the direction of the support bar 41, generating a squeezing force on the spring 1 44, and the spring 1 45 is pressed. 4 generates pressure on the arc block 45, so that the arc block 45 can fit more closely in the pre-tightening groove 46, thereby improving the stability during installation. At the same time, the movable plate 40 will drive the locking rod 57 to move toward the direction of the support bar 41, so that the locking rod 57 is inserted into the interior of the arc block 45 and the support bar 41, and the support bar 41 is locked again, thereby preventing the arc block 45 from being separated from the arc block 45 due to the arc shape under the influence of strong wind. In addition, there is no need to tighten multiple bolts, which simplifies the installation steps and improves the installation efficiency.

[0047] Example 3, refer to Figure 1-Figure 7 , a quickly installed antenna bracket, comprising an antenna bracket body 1 for connecting an antenna, a bottom plate 2 being fixed to the bottom of the antenna bracket body 1, a base 3 fixed to the ground being provided below the bottom plate 2, a pre-tightening portion for initially limiting the position of the antenna bracket body 1 being provided in the base 3, and further comprising:

[0048] A mounting mechanism is arranged in the base 3, and the mounting mechanism is used to lock the bottom plate 2 and the base 3;

[0049] The squeezing mechanism is installed on the base 3, and is used to clamp the antenna bracket body 1 and lock the installation mechanism at the same time.

[0050] Furthermore, the extrusion mechanism includes a torsion bar 61 fixed at the end of the rotating rod 58, a mounting shell 62 is fixed on the base 3, a spring three 63 is fixed in the mounting shell 62, a moving block 64 is fixed to the end of the spring three 63, a semicircular groove block 65 is fixed on the side of the moving block 64 close to the torsion bar 61, an arc groove 66 is opened on the semicircular groove block 65, an arc block three 67 is fixed on the torsion bar 61, and the arc block three 67 is clamped in the arc groove 66.

[0051] Furthermore, a stabilizing mechanism for further applying pressure to the antenna bracket body 1 is provided on the mounting shell 62, and the stabilizing mechanism includes an air cushion 71 fixed between the moving block 64 and the inner wall of the mounting shell 62, and the outer surface of the air cushion 71 is connected to a hose 72, a rectangular shell 73 is fixed on the base 3, an air bag 74 is fixed in the rectangular shell 73, one end of the hose 72 away from the air cushion 71 is connected to the air bag 74, a rectangular block 75 is fixed at the end of the air bag 74, and the rectangular block 75 slides in the rectangular shell 73.

[0052] Furthermore, a limiting block 76 is fixed in the rectangular shell 73, and an extrusion strip 77 is fixed on the side of the rectangular block 75 away from the airbag 74. The extrusion strip 77 is slidably connected to the limiting block 76. A spring four 78 is sleeved on the outer surface of the extrusion strip 77, and both ends of the spring four 78 are fixedly connected to the rectangular block 75 and the limiting block 76 respectively.

[0053] When the torsion bar 61 is twisted to drive the rotating rod 58 to rotate and limit the support bar 41, considering that the torsion bar 61 will rotate under the action of external force, the torsion bar 61 can be locked by setting the squeezing mechanism to prevent the torsion bar 61 from rotating independently, so that the antenna bracket body 1 can be firmly fixed. In addition, while locking the torsion bar 61 by the squeezing mechanism, the stabilizing mechanism can also be started simultaneously. During the outward sliding process of the squeezing bar 77, a lateral supporting force is applied to the antenna bracket body 1, thereby enhancing the stabilizing effect on the antenna bracket body 1 from multiple directions and reducing the possibility of strong winds blowing the antenna bracket body 1 from the side. It is like adding a protective barrier to the antenna bracket body 1, so that it can remain stable in a complex wind environment, improve the reliability after installation, and reduce the risk of loosening due to strong winds.

[0054] Specifically, when the torsion bar 61 rotates to a horizontal state, the arc block three 67 will contact the semicircular groove block 65. Due to the elastic force of the spring three 63, backward pressure will be exerted on the semicircular groove block 65 and the movable block 64, so that the arc block three 67 is inserted into the arc groove 66, thereby locking the torsion bar 61. In order to ensure stability, the torsion bar 61 and the semicircular groove block 65 can be made of magnets, which can further improve stability through magnetism.

[0055] In addition, when the moving block 64 moves backward, it will squeeze the air cushion 71, so that the gas in the air cushion 71 enters the air bag 74 through the hose 1 72. The air bag 74 expands due to the injection of gas, thereby driving the rectangular block 75 to move in the direction of the limit block 76, squeezing the spring four 78, which is connected to the rectangular block 75 through the squeezing strip 77. When the rectangular block 75 moves, it will also drive the squeezing strip 77 to move together, so that the squeezing strip 77 can apply a lateral supporting force to the bottom plate 2 to maintain stability during installation.

[0056] Embodiment 4, referring to Figure 1-Figure 7 , a quickly installed antenna bracket, comprising an antenna bracket body 1 for connecting an antenna, a bottom plate 2 being fixed to the bottom of the antenna bracket body 1, a base 3 fixed to the ground being provided below the bottom plate 2, a pre-tightening portion for initially limiting the position of the antenna bracket body 1 being provided in the base 3, and further comprising:

[0057] A mounting mechanism is arranged in the base 3, and the mounting mechanism is used to lock the bottom plate 2 and the base 3;

[0058] The squeezing mechanism is installed on the base 3, and is used to clamp the antenna bracket body 1 and lock the installation mechanism at the same time.

[0059] Furthermore, a clamping mechanism for applying pressure to the antenna bracket body 1 again is provided on the extrusion strip 77, and the clamping mechanism includes an L-shaped block 81 fixed on the extrusion strip 77, and a connecting block 82 is fixed at one end of the L-shaped block 81 away from the extrusion strip 77, and a fixing cylinder 83 is fixed on the connecting block 82, and a piston disk 84 slides in the fixing cylinder 83, and a lifting rod 85 is fixed to the bottom end of the piston disk 84, and the lifting rod 85 is slidably connected to the fixing cylinder 83 and the connecting block 82, and a clamping plate 86 is fixed to the bottom end of the lifting rod 85, and a spring 5 87 is sleeved on the outer surface of the lifting rod 85, and the two ends of the spring 5 87 are respectively fixedly connected to the piston disk 84 and the fixing cylinder 83.

[0060] Furthermore, a piston disk 88 is fixed to one end of the slide rod 52 located in the liquid storage cylinder 51, and the piston disk 88 slides in the liquid storage cylinder 51. The outer surface of the liquid storage cylinder 51 is connected to a hose 89, and the end of the hose 89 away from the liquid storage cylinder 51 is connected to the fixed cylinder 83.

[0061] It is fixed on the extrusion bar 77 through the L-shaped block 81. When the extrusion bar 77 moves to clamp the base plate 2, it will also drive the L-shaped block 81 and the connecting block 82 to move above the base plate 2. When the arc block 2 54 is squeezed by the cam 59 and drives the slide bar 52 to slide in the liquid storage cylinder 51, it will also drive the piston plate 2 88 to slide in the liquid storage cylinder 51, squeeze the liquid in the liquid storage cylinder 51, and make the liquid flow into the fixed cylinder 83 through the hose 2 89. Since the piston plate 1 84 slides in the fixed cylinder 83, the piston plate 1 84 will move downward after being squeezed by the fluid, thereby driving the clamping plate 86 and the lifting rod 85 to move downward, compressing the base plate 2 and squeezing the spring 5 87.

[0062] A further benefit of adopting the above is that, with the coordinated action of the installation mechanism, the squeezing mechanism and the stabilizing mechanism, pressure can be applied again from the top to ensure that the antenna bracket body 1 is firmly fixed in all directions and at multiple levels. Even under the continuous impact of strong winds, the installation firmness of the antenna bracket body 1 can be guaranteed, thereby improving the stability of the operation of the communication system.

[0063] 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 according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
