An omnidirectional antenna assembly with multi-point limiting

Abstract

This utility model discloses an omnidirectional antenna assembly with multi-point limiting, relating to the field of omnidirectional antenna technology. It includes a lower fixing rod and an operating box. The operating box is fixed inside the lower fixing rod, and an upper fixing rod is rotatably connected inside the operating box. In this utility model, an operator can push a support rod upwards from the bottom of the lower fixing rod via a pusher seat, causing a flexible limiting clip to move upwards along the antenna radiator. The flexible limiting clip maintains flexible contact with the antenna radiator, avoiding rigid fixation. This allows for thermal expansion and contraction or minor deformation, and preserves the natural swing margin of the antenna radiator, preventing structural damage under extreme weather conditions. After the upward movement is complete, the support rod can be fixed from the bottom, with simultaneous fixation from the top. This, combined with the fixing clamp structure used in existing technologies, forms a dual-point support, reducing swaying and improving the limiting effect.

Description

Technical Field

[0001] This utility model relates to the field of omnidirectional antenna technology, and in particular to an omnidirectional antenna assembly with multi-point limiting. Background Technology

[0002] In the new context of shunting development, there is a trend towards centralized office work for shunting section chiefs. In this context, the shunting section chief has the ability to monitor the operational needs of multiple shunting teams. This allows for voice communication between the shunting section chief and multiple shunting teams, and the shunting section chief can view the communication status and shunting instructions displayed on the section chief's control console. This enables the shunting section chief to have real-time control over the operational status of each shunting team. The front-end equipment of the section chief's control system utilizes a high-power onboard radio to increase transmission power, and also employs a high-gain omnidirectional antenna to ensure that the wireless signal of the section chief's control system's front-end equipment can cover the entire area of ​​shunting operations at the station.

[0003] Existing omnidirectional antenna assemblies often use two sets of fixing clips to secure the fixing tube at the bottom of the antenna, with a long rod-shaped radiator on top. However, during use, the fixing clips only provide basic support at the bottom, and the long rod-shaped radiator is greatly affected by wind, making it prone to swaying or deformation, which affects signal stability. There is room for optimization, so it is necessary to design an omnidirectional antenna assembly with multi-point limiting to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this invention is to provide an omnidirectional antenna assembly with multi-point limiting, so as to solve the problem of poor antenna limiting effect mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an omnidirectional antenna assembly with multi-point limiting, comprising a lower fixing rod and an operation box, wherein the operation box is fixed inside the lower fixing rod; The operation box is rotatably connected to an upper fixed rod, the top of which extends above a lower fixed rod. The lower fixed rod has a receiving groove inside, and a push seat is movably connected to the bottom of the receiving groove. Both sides of the push seat extend to the outside of the lower fixed rod. A support rod is fixed to the top of the push seat, and the top of the support rod extends through the support rod, the operation box, and the upper fixed rod to the top of the upper fixed rod. A turntable is rotatably connected to the top of the support rod, and a flexible limit card is connected to one side of the flexible limit card. An antenna fixing tube is fixed to one side of the upper fixed rod by a fixing clamp, and an antenna radiator is fixed to the top of the antenna fixing tube.

[0006] Furthermore, a worm gear is fixed to the outer side of the upper fixing rod, a worm is connected inside the operation box, and the worm and the worm gear are meshed together. A motor is fixed to one side of the operation box, and the output shaft of the motor is connected to the worm.

[0007] Furthermore, the lower fixing rod has grooves evenly arranged inside, and each groove is connected to a ball bearing.

[0008] Furthermore, all the balls are in contact with the upper fixed rod, and the balls are arranged in a ring on the outside of the upper fixed rod.

[0009] Furthermore, handles are fixed on both sides of the push base, and anti-slip textures are provided on the outer side of each handle.

[0010] Furthermore, each of the push bases has a locking plate fixed to its top, and each locking plate has a locking groove inside. Each of the two sides of the bottom of the operation box has a rotating groove, and each rotating groove is connected to a rotating block. Each rotating block has a locking rod fixed to its bottom end, and each locking rod has an anti-slip locking block fixed to its bottom end.

[0011] Furthermore, the bottom ends of the anti-slip locking blocks all penetrate the interior of the locking groove and extend to the bottom of the locking plate, and the top surface of the anti-slip locking blocks is in contact with the bottom surface of the locking plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the omnidirectional antenna assembly with multi-point limiting realizes the function of convenient multi-point limiting; By setting a support rod that can extend from the top at the inner bottom of the lower fixed rod, and setting a flexible limiting clip at the top of the support rod, the operator can push the support rod upward via the push seat at the bottom of the lower fixed rod to move the flexible limiting clip upward along the antenna radiator. The flexible limiting clip and the antenna radiator maintain flexible contact and are not rigidly fixed, which allows for thermal expansion and contraction or slight deformation and retains the natural swing margin of the antenna radiator to prevent structural damage under extreme weather conditions. After the upward movement is completed, the support rod can be fixed from the bottom and simultaneously fixed from the top. This, together with the fixing clip structure used in the existing technology, forms a double-point support, reduces shaking, and improves the limiting effect. In the aforementioned technology, when the push base moves upward, both the locking groove and the anti-slip locking block are designed longitudinally. During the pushing process, the anti-slip locking block passes through the locking groove and extends to the bottom of the locking plate. Then, by rotating the anti-slip locking block so that it is parallel to the locking groove, the locking can be achieved. Furthermore, the anti-slip locking block and the bottom surface of the locking plate are in contact to generate friction, making it less prone to shaking. Conversely, it can be disassembled without the need for personnel to perform fixing operations at a high position on the antenna radiator, thus improving safety. Attached Figure Description

[0016] 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 scope of protection of the present utility model.

[0017] Please see Figures 1-6 The present invention provides the following technical solution: Example 1: To address the problem of poor antenna positioning in existing technologies, the following solution is disclosed, specifically as follows: Figures 1-6As shown, the omnidirectional antenna assembly with multi-point limiting provided in this application includes a lower fixing rod 8 and an operation box 9. The operation box 9 is fixed inside the lower fixing rod 8, and an upper fixing rod 6 is rotatably connected inside the operation box 9. The top end of the upper fixing rod 6 extends above the lower fixing rod 8. A receiving groove 10 is provided inside the lower fixing rod 8, and a push seat 13 is movably connected to the bottom end of the receiving groove 10. Both sides of the push seat 13 extend to the outside of the lower fixing rod 8. A support rod 7 is fixed to the top end of the push seat 13, and the top end of the support rod 7 extends through the interior of the support rod 7, the operation box 9, and the upper fixing rod 6 to the top of the upper fixing rod 6. A turntable 2 is rotatably connected to the top end of the support rod 7, and a flexible limiting card 3 is connected to one side of the flexible limiting card 3. An antenna fixing tube 4 is fixed to one side of the upper fixing rod 6 by a fixing clamp 5, and an antenna radiator 1 is fixed to the top of the antenna fixing tube 4. Handles are fixed to both sides of the push seat 13, and anti-slip textures are provided on the outer side of the handles. A locking plate 11 is fixed to the top of the push seat 13, and a locking groove 12 is provided inside the locking plate 11. Rotating grooves 22 are provided on both sides of the bottom of the operation box 9, and rotating blocks 21 are connected inside the rotating grooves 22. A locking rod 20 is fixed to the bottom of the rotating block 21, and an anti-slip locking block 19 is fixed to the bottom of the locking rod 20. The bottom of the anti-slip locking block 19 passes through the interior of the locking groove 12 and extends to the bottom of the locking plate 11. The top surface of the anti-slip locking block 19 is in contact with the bottom surface of the locking plate 11.

[0018] In this embodiment, during use, a support rod 7 that can extend from the top is set at the inner bottom of the lower fixed rod 8, and a flexible limiting card 3 is set at the top of the support rod 7. The operator can push the support rod 7 upward at the bottom of the lower fixed rod 8 via the push seat 13 to make the flexible limiting card 3 move upward along the antenna radiator 1. The flexible limiting card 3 and the antenna radiator 1 maintain flexible contact and are not rigidly fixed, which allows for thermal expansion and contraction or slight deformation and retains the natural swing margin of the antenna radiator 1 to prevent structural damage under extreme weather conditions. After the upward movement is completed, the support rod 7 can be fixed from the bottom and simultaneously fixed from the top, thereby forming a double-point support with the fixing clip 5 structure used in the prior art, reducing shaking and improving the limiting effect. In the above-mentioned technology, when the push seat 13 moves upward, both the locking groove 12 and the anti-slip locking block 19 are designed longitudinally. During the pushing process, the anti-slip locking block 19 passes through the locking groove 12 and extends to the bottom of the locking plate 11. Then, by rotating the anti-slip locking block 19 so that it is parallel to the locking groove 12, the locking can be achieved. The anti-slip locking block 19 and the bottom surface of the locking plate 11 are in contact to generate friction, making it less prone to shaking.

[0019] Example 2: This example differs from Example 1 in that it uses a directional adjustment mechanism to achieve horizontal rotation angle adjustment of the antenna. Specifically, as shown below... Figure 1 and Figure 3 As shown, a worm gear 16 is fixed to the outer side of the upper fixed rod 6, and a worm 18 is connected inside the operation box 9, with the worm 18 and the worm gear 16 meshing together. A motor 17 is fixed to one side of the operation box 9, and the output shaft of the motor 17 is connected to the worm 18. Grooves 14 are evenly arranged inside the lower fixed rod 8, and balls 15 are connected inside each groove 14. The balls 15 are in contact with the upper fixed rod 6, and the balls 15 are arranged in a ring on the outer side of the upper fixed rod 6.

[0020] In this embodiment, during use, the starting motor 17 drives the worm gear 18 to rotate, and the worm wheel 16 rotates synchronously under meshing to drive the upper fixed rod 6 to rotate. This allows for quick and fine adjustment of the antenna's horizontal rotation angle, improving its practicality and flexibility. At the same time as the rotation, the turntable 2 rotates synchronously on the top of the support rod 7, so that the limiting component is not affected.
