Description

Technical Field

[0001] The present invention relates to the field of connectors, and more particularly to a connector for a communication tower. Background Art

[0002] Communication tower is a tall steel structure, mainly used for transmission and emission of microwave, ultra-short wave and wireless network signals, and is an indispensable infrastructure in the communication network system. Communication tower is mainly composed of steel components such as tower body, platform, lightning rod, ladder, antenna connector, etc., and is treated with hot-dip galvanizing to ensure its stability and durability. This design not only ensures the stability of the tower body, but also extends its service life.

[0003] According to different structural forms, communication towers can be divided into many types, including angle steel towers, steel tube towers, single tube towers, guyed towers, pole towers, landscape towers, etc. Each type has its own unique advantages and scope of application. For example, angle steel towers have a stable structure and are suitable for various environments; pole towers have a simple structure, are economical and practical, and are usually installed on the roof; landscape towers focus on aesthetics and are coordinated with the surrounding environment.

[0004] Connectors are needed to connect the antenna to the tower body on the communication tower. Traditional connectors are prone to loosening at the connection when they are repeatedly blown for a long time, which can cause the angle position of the communication antenna to shift or even fall off. To avoid this situation, the maintenance time needs to be shortened, and frequent maintenance is required, which is extremely cumbersome.

[0005] In view of this, and in view of the above-mentioned shortcomings, the present invention develops a connecting piece for a communication tower. Summary of the invention

[0011] Furthermore, a plurality of evenly distributed conical blocks are fixedly mounted on the lower surface of the first rotating member, and a plurality of evenly distributed matching grooves are formed on the upper surface of the second rotating member. The matching grooves are formed by combining a first inclined surface and a second inclined surface.

[0012] Furthermore, a rotating sleeve is provided on the outer surface of the rotating shell through a threaded fitting, a movable ring is rotatably installed above the rotating sleeve, the movable ring is slidably sleeved on the outer surface of the rotating shell, a movable plate is fixedly installed on the inner ring of the movable ring, the movable plate is located inside the rotating shell, and a first spring is fixedly connected between the movable plate and the first rotating member.

[0013] Furthermore, a plurality of evenly distributed circular grooves are provided at one end of the upper connecting plate away from the rotating shell, a connecting groove is provided between two adjacent circular grooves, a lower connecting plate is provided below the end of the upper connecting plate away from the rotating shell, and the lower connecting plate is rotatably mounted on one side of the communication antenna.

[0014] Furthermore, a limiting sleeve is provided inside the circular groove, and the internal sliding card of the limiting sleeve is provided with a first sliding rod. The upper surface of the lower connecting plate is also provided with a circular groove and a connecting groove, and the interior of the lower connecting plate is provided with a third sliding groove connected to the circular groove and the connecting groove, and the internal sliding card of the third sliding groove is provided with a sliding block.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. This solution provides a locking member and a matching kit. When the second rotating member is driven to rotate, it will simultaneously descend along the sliding sleeve, and then the second rotating member will push the locking member. When the locking member is pushed, it will cooperate with the matching kit to clamp the surface of the mounting frame, thereby achieving tightening. When the communication antenna is blown back and forth by the wind, it can achieve self-locking. As the airflow changes faster and the wind force becomes stronger, the connection can be tightened more, reducing the probability of loosening, reducing the maintenance frequency, reducing the workload of workers, and being easy to use.

[0021] 2. This solution sets a limit block and a limit plate. When the rotating shell rotates, the limit block will be driven to rotate, while the sliding sleeve does not rotate relative to the mounting frame. Therefore, the limit plate will move between the two limit blocks, thereby limiting the rotation angle of the rotating shell to prevent the rotation angle from being too large, causing line torsion or damage to other structural parts, and allowing it to rotate back and forth within a certain angle. This not only increases the locking ability but also plays a role in limiting and preventing damage.

[0022] 3. This solution can also prevent the situation where parts are squeezed and damaged due to over-tightening of the device by setting a rotating sleeve. The locking threshold can also be changed by adjusting the rotating sleeve, which is convenient for adapting to different seasons and climates and improving the service life of the device. In strong wind areas, the connection strength between the conical block and the second rotating part can be reduced to prevent excessive wind from causing the second rotating part to be over-locked, causing damage to the thread or the mating kit and other devices, making it easier to pass through the mating slot, and can play a role in protecting the device by changing the threshold.

[0023] 4. This solution and this device are provided with a rotating sleeve and a moving ring, so that it can not only adjust the threshold, but also quickly disassemble the device so that it loses support from the mounting frame, which is convenient for adjusting the height or disassembly and maintenance, etc., saving maintenance and disassembly time.

[0024] 5. This device is provided with a limit sleeve, and the engagement and release can be achieved by pressing and rotating the limit sleeve. There is no need to disassemble the parts during the adjustment process. The angle and distance of the communication antenna can be adjusted by sliding the position of the limit sleeve to offset the upper connecting plate and the lower connecting plate. Even if the worker fails, the communication antenna will not fall. The operation is simple and the adjustment is convenient. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] 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; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0039] See also Figures 1 to 11A connecting piece of a communication tower comprises a tower body, a maintenance platform is installed on the tower body, a plurality of mounting frames 1 distributed in a ring are installed on the maintenance platform, each mounting frame 1 is connected to a communication antenna 3 through a plurality of connecting piece bodies 2, the connecting piece body 2 comprises an upper connecting plate 21, a rotating shell 22 is fixedly installed on the lower surface of one end of the upper connecting plate 21, the rotating shell 22 and the upper connecting plate 21 are both sleeved on the outside of the mounting frame 1, a sliding sleeve 25 is rotatably provided on the upper inner portion of the rotating shell 22, and the sliding sleeve 25 is slidably sleeved on the outer surface of the mounting frame 1, A plurality of groups of limiting components are fixedly installed inside the rotating shell 22, and the limiting components are composed of two limiting blocks 221. A plurality of limiting plates 251 corresponding to the limiting components are fixedly installed at the outer ring of the sliding sleeve 25, and the limiting plate 251 is located between the two limiting blocks 221. A first rotating member 26 is slidably provided at the middle position inside the rotating shell 22, and a second rotating member 27 is provided below the first rotating member 26. The second rotating member 27 is sleeved on the outer surface of the sliding sleeve 25 through threaded cooperation, and a locking member 28 is rotatably installed below the second rotating member 27.

[0040] In actual use, because there will be many communication antennas 3 on the communication tower, the communication antenna 3 is used to receive and send signals, and the communication antenna 3 is also large in size, and the communication antenna 3 is located at the top of the communication tower, so the communication antenna 3 is easily blown and shaken repeatedly by the airflow during use. This situation is particularly obvious in some monsoon climate areas, and traditional connectors are prone to loosening at the connection when repeatedly blown for a long time, which may cause the angle position of the communication antenna 3 to shift or even fall off. To avoid this situation, it is necessary to shorten the maintenance time, and frequent maintenance is required, which is extremely cumbersome.

[0041] Therefore, the device is provided with a locking member 28 and a matching set 29. When the communication antenna 3 is blown, the upper connecting plate 21 will be driven to rotate around the mounting frame 1. When the upper connecting plate 21 rotates, the rotating shell 22 will be driven to rotate. Because the sliding sleeve 25 is slidably sleeved on the outside of the mounting frame 1, the sliding sleeve 25 does not rotate relative to the mounting frame 1. When the rotating shell 22 rotates, the first rotating member 26 will be driven to rotate. The rotation of the first rotating member 26 can drive the second rotating member 27 to rotate. The first rotating member 26 can only drive the second rotating member 27 to rotate in one direction. When the second rotating member 27 rotates, it will descend along the sliding sleeve 25, and then the second rotating member 27 will push the locking member 28. When the locking member 28 is pushed, it will cooperate with the matching set 29 to clamp the surface of the mounting frame 1, thereby achieving tightening. When the communication antenna 3 is blown back and forth by the wind, self-locking can be achieved. As the airflow changes faster and the wind force is greater, the connection can be more tightly connected, reducing the probability of loosening, reducing the maintenance frequency, reducing the workload of workers, and being easy to use.

[0042] When airflow blows the communication antenna 3, in order to prevent the rotating shell 22 from rotating too much, a limit block 221 and a limit plate 251 are provided. When the rotating shell 22 rotates, the limit block 221 is driven to rotate, while the sliding sleeve 25 does not rotate relative to the mounting frame 1, so the limit plate 251 moves between the two limit blocks 221, thereby limiting the rotation angle of the rotating shell 22 to prevent the rotation angle from being too large, causing line twisting or damage to other structural parts, so that the rotating shell 22 can rotate back and forth within a certain angle, which can not only increase the locking ability but also play a role in limiting the ability to prevent damage.

[0043] The locking member 28 is slidably mounted on the sliding sleeve 25, and a matching set 29 is provided below the locking member 28. A plurality of evenly distributed second slide bars 285 are fixedly mounted on the lower surface of the locking member 28, and a plurality of second slide grooves 292 corresponding to the second slide bars 285 are provided on the matching set 29. A conical inclined groove 291 is provided in the middle of the matching set 29. A plurality of evenly distributed locking teeth 282 are slidably mounted on the lower surface of the locking member 28, and the locking teeth 282 are fitted with the surface of the mounting frame 1. A plurality of evenly distributed T-shaped slide grooves 281 are provided inside the locking member 28, and a T-shaped slider 283 is fixedly mounted on the locking teeth 282. The T-shaped slider 283 is slidably mounted inside the corresponding T-shaped slide groove 281, and a second spring 284 is fixedly connected between the T-shaped slider 283 and the T-shaped slide groove 281.

[0044] When the locking member 28 descends, the locking member 28 pushes the locking tooth 282 to descend, and the locking tooth 282 will gradually enter the interior of the conical inclined groove 291. Because the conical inclined groove 291 is in an inverted cone shape, and the outer surface of the locking tooth 282 is also inclined, when the locking tooth 282 descends, it will be pushed by the conical inclined groove 291 to slide along the T-shaped slide groove 281. At this time, the locking tooth 282 is pushed to squeeze the mounting frame 1. When the wind force is greater, the locking member 28 descends more, and then it can be self-locking, and the second spring 284 is used to reset the locking tooth 282.

[0045] A rotating sleeve 23 is provided on the outer surface of the rotating shell 22 through a threaded fitting sleeve, and a moving ring 24 is rotatably installed above the rotating sleeve 23. The moving ring 24 is slidably sleeved on the outer surface of the rotating shell 22, and a moving plate 241 is fixedly installed on the inner ring of the moving ring 24. The moving plate 241 is located inside the rotating shell 22, and a first spring 242 is fixedly connected between the moving plate 241 and the first rotating member 26. A plurality of evenly distributed conical blocks 261 are fixedly installed on the lower surface of the first rotating member 26, and a plurality of evenly distributed matching grooves 271 are provided on the upper surface of the second rotating member 27. The matching grooves 271 are formed by a combination of a first inclined surface 2711 and a second inclined surface 2712, and the slope of the first inclined surface 2711 is greater than the slope of the second inclined surface 2712.

[0046] When in use, the first rotating member 26 is rotated to make it rise or fall along the surface of the rotating shell 22. When the first rotating member 26 moves, it will drive the moving ring 24 to move, and the movement of the moving ring 24 drives the moving plate 241 to move. The descending of the moving plate 241 will squeeze the first spring 242, and then the first spring 242 will have a stronger pushing effect on the first rotating member 26. When the first rotating member 26 is pushed, the conical block 261 will enter the interior of the matching groove body 271. When the rotating shell 22 rotates forward, it will drive the first rotating member 26 to rotate forward, and the first rotating member 26 drives the second rotating member 27 to rotate forward. When the rotating shell 22 is reversed, due to the friction between the second rotating member 27 and the sliding sleeve 25 and the second inclined surface 2712, the second rotating member 27 will not reverse, and then the second rotating member 27 can continue to descend for self-locking. Because of the inclined design of surface 2712, when the locking tooth 282 completely clamps the mounting frame 1, the locking member 28 cannot descend, and the second rotating member 27 cannot rotate. At this time, the rotating shell 22 continues to rotate under the action of wind, which will cause the conical block 261 to slide along the first inclined surface 2711. At this time, the locking threshold is reached, which can prevent the device from being over-locked and causing parts to be squeezed and damaged. The locking threshold can also be changed by adjusting the rotating sleeve 23, which is convenient for adapting to different seasons and climates and improving the service life of the device. During installation, the position of the moving ring 24 is changed according to the local climate. In strong wind areas, because it is necessary to resist greater force, it is necessary to rotate the rotating sleeve 23 to descend, so that the conical block 261 exerts greater pressure on the matching groove body 271. At this time, the force required for the conical block 261 to overcome the first inclined surface 2711 is greater, thereby increasing the threshold, and vice versa.

[0047] When the connecting member body 2 needs to be disassembled or repaired, the rotating shell sleeve 23 can be rotated to make the moving plate 241 completely compress the first spring 242 into the interior of the first rotating member 26. At this time, the moving plate 241 will resist the first rotating member 26, and the first rotating member 26 cannot move, resulting in the second rotating member 27 being fixed and unable to rotate. At this time, the rotating shell 22 is rotated in the opposite direction, and the rotating shell 22 will drive the first rotating member 26 to reverse, and the first rotating member 26 will drive the second rotating member 27 to reverse, and then the second rotating member 27 will rise along the surface of the sliding sleeve 25. The rise of the second rotating member 27 will drive the locking member 28 and the locking tooth 282 to rise. Under the action of the second spring 284, the locking tooth 282 will be reset and lose the clamping effect on the mounting frame 1. Therefore, the device is provided with a rotating sleeve 23 and a moving ring 24, so that it can not only adjust the threshold, but also quickly disassemble the device, so that it loses support with the mounting frame 1, which is convenient for adjusting the height or disassembly and maintenance, etc., saving maintenance and disassembly time.

[0048] A plurality of evenly distributed circular grooves 211 are formed at one end of the upper connecting plate 21 away from the rotating shell 22 , and a connecting groove 212 is formed between two adjacent circular grooves 211 . A lower connecting plate 213 is provided below the end of the upper connecting plate 21 away from the rotating shell 22 , and the lower connecting plate 213 is rotatably mounted on one side of the communication antenna 3 .

[0049] A limiting sleeve 216 is provided inside the circular groove 211, and a first sliding rod 217 is provided on the internal sliding card of the limiting sleeve 216. A circular groove 211 and a connecting groove 212 are also provided on the upper surface of the lower connecting plate 213. A third sliding groove 214 connected to the circular groove 211 and the connecting groove 212 is provided inside the lower connecting plate 213, and a sliding block 215 is provided on the internal sliding card of the third sliding groove 214. The diameter of the circular groove 211 is greater than the width of the connecting groove 212, the outer ring diameter of the limiting sleeve 216 is equal to the diameter of the circular groove 211, and the diameter of the first sliding rod 217 is less than the width of the connecting groove 212.

[0050] A central groove 2151 is provided in the middle of the sliding block 215, and a plurality of L-shaped grooves 2152 are provided in the inner circle of the central groove 2151. A connecting sleeve 218 is integrally formed at the lower end of the limiting sleeve 216, and a plurality of clamping blocks 219 corresponding to the L-shaped grooves 2152 are fixedly installed at the lower end of the outer surface of the connecting sleeve 218. The connecting sleeve 218 is clamped inside the central groove 2151, and a third spring 2153 is rotatably connected between the connecting sleeve 218 and the central groove 2151. The first sliding rod 217 is fixedly installed in the middle of the central groove 2151.

[0051] In order to make the communication antenna 3 receive and send signals better, it is usually necessary to adjust the angle. When adjusting the traditional connecting parts, the bolts need to be removed and the angle of the connecting parts need to be adjusted. After the adjustment, the bolts need to be tightened. This not only requires workers to lift and disassemble the communication antenna 3 for a long time, but also easily causes the workers to accidentally cause the communication antenna 3 to fall, or the bolts to fall during the disassembly process, making the adjustment work difficult.

[0052] When the angle and distance of the communication antenna 3 need to be adjusted, the limiting sleeve 216 can be pressed first. At this time, the third spring 2153 is compressed. Then the limiting sleeve 216 is rotated and the limiting sleeve 216 is released. At this time, the block 219 will slide out from the inside of the third spring 2153, thereby losing its effect on the limiting sleeve 216. At this time, the third spring 2153 will push the limiting sleeve 216 out of the circular groove 211. At this time, the lower connecting plate 213 and the upper connecting plate 21 can be staggered. At this time, the sliding block 215 will slide along the inside of the third sliding groove 214, and the first sliding rod 217 will slide along the inside of the connecting groove 212. When it moves to the desired position, it is only necessary to press the limiting sleeve 216 down again and rotate it so that the block 219 is stuck by the L-shaped groove 2152. Because the outer ring diameter of the limiting sleeve 216 is larger than the diameter of the connecting groove 212, the limiting sleeve 216 will fix the position of the lower connecting plate 213 at this time.

[0053] Therefore, the device is provided with a limiting sleeve 216, and the locking and releasing can be achieved by only pressing and rotating the limiting sleeve 216. There is no need to disassemble the parts during the adjustment process. The angle, distance, etc. of the communication antenna 3 can be adjusted by sliding the position of the limiting sleeve 216 to offset the upper connecting plate 21 and the lower connecting plate 213. Even if the worker fails, the communication antenna 3 will not fall. The operation is simple and the adjustment is convenient.

[0054] The above is only a preferred specific implementation of the present invention; however, 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 solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
