Description

Technical Field

[0001] This utility model relates to the field of subway communication antenna technology, and more specifically, to an installation structure for a subway communication antenna. Background Technology

[0002] An antenna is a transducer that transforms guided waves propagating on a transmission line into electromagnetic waves propagating in an unbounded medium (usually free space), or vice versa. It is a component in wireless equipment used to transmit or receive electromagnetic waves. Engineering systems such as radio communication, broadcasting, television, radar, navigation, electronic countermeasures, remote sensing, and radio astronomy all rely on antennas to transmit information using electromagnetic waves. With the construction and use of more and more subways and light rails, while people are enjoying the convenience and speed brought by the rapid development of urban rail transit, antennas need to be installed in multiple locations to achieve wide-area wireless network coverage.

[0003] Chinese patent CN202323642141.7 discloses an installation structure for a subway communication antenna. This utility model includes a horizontal mounting rod, a mounting bracket, an arc-shaped adjustment port, adjustment bolts, adjustment nuts, and a waist-shaped hole. It allows for adjustable installation of the subway communication antenna, enabling it to meet different angle installation requirements, facilitating installation and improving efficiency. However, certain problems remain. The horizontal mounting rod and the insertion rod are connected via adjustment bolts and nuts in conjunction with the waist-shaped hole. While the height of the horizontal mounting rod can be adjusted to regulate the height of the communication antenna body, two sets of adjustment bolts and nuts are arranged vertically. This is inconvenient during installation, and if the adjustment bolts and nuts become loose, the horizontal mounting rod and the entire communication antenna body will automatically fall, resulting in poor stability. Therefore, we provide an installation structure for a subway communication antenna. Utility Model Content

[0004] The purpose of this utility model is to provide an installation structure for a subway communication antenna to solve the problems mentioned in the background art.

[0005] The two sets of adjusting bolts and nuts are distributed vertically, which makes installation inconvenient. Furthermore, if the adjusting bolts and nuts become loose, the mounting bar and the entire communication antenna will automatically fall, resulting in poor stability.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An installation structure for a subway communication antenna includes a mounting base. A mounting sleeve is fixedly connected to the top of the mounting base. An adjusting rod is slidably connected inside the mounting sleeve. A fixed seat is fixedly connected inside the mounting sleeve. A rotating plate is rotatably connected to the outside of the fixed seat. A sliding groove is formed inside the rotating plate. A first sliding rod is slidably connected to the inside of the sliding groove near the fixed seat. The first sliding rod is fixedly connected to the adjusting rod. A threaded rod is rotatably connected inside the mounting sleeve. A slider is sleeved on the outside of the threaded rod. The slider is threadedly connected to the threaded rod. A second sliding rod is slidably connected to the inside of the sliding groove away from the fixed seat. The second sliding rod is fixedly connected to the slider.

[0008] Preferably, both the mounting sleeve and the adjusting rod have square cross-sections, and the outer wall of the adjusting rod fits against the inner wall of the mounting sleeve.

[0009] Preferably, the outer wall of the slider is fitted to the inner wall of the mounting sleeve, and the slider and the mounting sleeve are slidably connected.

[0010] Preferably, a mounting horizontal bar is sleeved on the outside of the adjusting rod, the mounting horizontal bar is detachably connected to the adjusting rod, a mounting bracket is rotatably connected to the outside of the mounting horizontal bar, a communication antenna body is fixedly connected to the outside of the mounting bracket, an arc-shaped adjusting port is opened inside the mounting bracket, a locking bolt is slidably connected inside the arc-shaped adjusting port, and the locking bolt is threadedly connected to the mounting horizontal bar.

[0011] Preferably, the outer walls of both the first and second slide rods are in contact with the inner wall of the slide groove.

[0012] Preferably, the slider has a U-shaped structure.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] Rotating the threaded rod causes the slider to move, which in turn causes the second sliding rod to press against the inner wall of the groove. This allows the second sliding rod, in conjunction with the groove, to rotate the rotating plate on the fixed base at a small angle. When the rotating plate rotates, it presses against the first sliding rod through the inner wall of the groove. At this point, the first sliding rod can move the adjusting rod up and down within the mounting sleeve, thereby moving the mounting horizontal rod mounted on the adjusting rod up and down. This achieves the purpose of adjusting the height of the communication antenna body. Because the slider has a self-locking capability under the action of the threaded rod, the slider will not move if the threaded rod does not rotate, and the rotating plate will not rotate if the slider does not move, thus preventing the adjusting rod from moving on its own. This ensures the stability of the adjusting rod and makes the adjustment operation convenient. Attached Figure Description

[0020] 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.

[0021] Please see Figures 1 to 4 An installation structure for a subway communication antenna includes a mounting base 1, a mounting sleeve 2 fixedly connected to the top of the mounting base 1, an adjusting rod 3 slidably connected inside the mounting sleeve 2, a fixed seat 4 fixedly connected inside the mounting sleeve 2, mounting holes at the four corners of the mounting base 1, a rotating plate 5 rotatably connected to the outside of the fixed seat 4, a sliding groove 6 inside the rotating plate 5, a first sliding rod 7 slidably connected to the side of the sliding groove 6 closest to the fixed seat 4, the first sliding rod 7 being fixedly connected to the adjusting rod 3, a threaded rod 8 rotatably connected inside the mounting sleeve 2, a slider 9 sleeved on the outside of the threaded rod 8, the slider 9 being threadedly connected to the threaded rod 8, a second sliding rod 10 slidably connected to the side of the sliding groove 6 furthest from the fixed seat 4, the second sliding rod 10 being fixedly connected to the slider 9. When the slider 9 moves, the second sliding rod 10, in conjunction with the sliding groove 6, drives the rotating plate 5 to rotate, and the rotating plate 5, in conjunction with the first sliding rod 7, drives the adjusting rod 3 to move up and down, thereby adjusting the height of the communication antenna body 13.

[0022] Furthermore, both the mounting sleeve 2 and the adjusting rod 3 have square cross-sections, and the outer wall of the adjusting rod 3 fits against the inner wall of the mounting sleeve 2.

[0023] Furthermore, the outer wall of the slider 9 is in contact with the inner wall of the mounting sleeve 2, and the slider 9 is slidably connected to the mounting sleeve 2. The mounting sleeve 2 is used to limit the slider 9. When the threaded rod 8 rotates, the threaded rod 8 can drive the slider 9 to move.

[0024] Furthermore, a mounting horizontal rod 11 is sleeved on the outside of the adjusting rod 3. The mounting horizontal rod 11 is detachably connected to the adjusting rod 3. A mounting bracket 12 is rotatably connected to the outside of the mounting horizontal rod 11. A communication antenna body 13 is fixedly connected to the outside of the mounting bracket 12. An arc-shaped adjustment port 14 is opened inside the mounting bracket 12. A locking bolt 15 is slidably connected inside the arc-shaped adjustment port 14. The locking bolt 15 is threadedly connected to the mounting horizontal rod 11. The mounting bracket 12 can rotate left and right on the mounting horizontal rod 11, and the locking bolt 15 locks the mounting bracket 12 and the mounting horizontal rod 11 together.

[0025] Furthermore, the outer walls of the first slide rod 7 and the second slide rod 10 are both in contact with the inner wall of the slide groove 6, and the first slide rod 7 and the second slide rod 10 are both in close contact with the slide groove 6, so that there is no excessive gap between the first slide rod 7 and the second slide rod 10 and the slide groove 6, which can ensure the stability between them and prevent wobbling and instability.

[0026] Furthermore, the slider 9 has a U-shaped structure. When the threaded rod 8 drives the slider 9 to move, the slider 9 will drive the rotating plate 5 on the fixed seat 4 to rotate through the second sliding rod 10 and the sliding groove 6. The U-shaped structure can prevent the rotating plate 5 and the slider 9 from hitting each other and getting stuck, ensuring that the rotating plate 5 can rotate normally.

[0027] The usage steps of this utility model are as follows: When using the installation structure of the local iron communication antenna, if it is necessary to adjust the height of the installation horizontal rod 11, the user only needs to rotate the threaded rod 8 on one side of the installation sleeve 2. When the threaded rod 8 rotates, it will drive the slider 9 to move. The slider 9 drives the second slide rod 10 to press against the inner wall of the slide groove 6, so that the second slide rod 10, in conjunction with the slide groove 6, can drive the rotating plate 5 on the fixed seat 4 to rotate at a small angle. When the rotating plate 5 rotates, it will press the first slide rod 7 through the inner wall of the slide groove 6. At this time, the first slide rod 7 can drive the adjusting rod 3 to move up and down in the installation sleeve 2, thereby driving the installation horizontal rod 11 installed on the adjusting rod 3 to move up and down, so as to achieve the purpose of adjusting the height of the communication antenna body 13. Since the slider 9 has a self-locking ability under the action of the threaded rod 8, that is, the slider 9 will not move if the threaded rod 8 does not rotate, and the rotating plate 5 will not rotate if the slider 9 does not move, so the adjusting rod 3 will not move by itself, thus ensuring the stability of the adjusting rod 3, and the adjustment operation is convenient.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
