Description

Technical Field

[0001] This utility model relates to the field of single-tube tower technology, and in particular to a single-tube tower with a connecting sleeve. Background Technology

[0002] Monotube towers are widely used in communication base stations, power line construction, and other fields due to their simple structure, small footprint, and low wind load coefficient. Currently, most monotube towers on the market are constructed by splicing multiple sections of circular tubes. Existing splicing methods mostly rely on direct bolt connections or welding fixation, which has significant limitations: bolt connections require high-altitude drilling and bolt tightening, necessitating precise alignment of bolt holes during installation, making the process cumbersome, time-consuming, and labor-intensive; while welding fixation offers higher connection strength, subsequent maintenance or disassembly requires cutting the weld points, which is complex and easily damages the circular tubes, making it difficult to achieve rapid assembly and flexible disassembly of monotube towers, and failing to meet the needs of efficient construction and subsequent modifications. Utility Model Content

[0003] To address the aforementioned issues, this utility model provides a socketed single-tube tower. By optimizing the socketed connection structure between circular tubes, it enables rapid assembly and stable connection of multiple circular tube segments, while also ensuring ease of disassembly and reducing the difficulty of installation and maintenance.

[0004] The technical solution of this utility model is as follows:

[0005] A single-tube tower includes several circular tubes. Each circular tube has a sleeve at its top, the top of which is used to fit the bottom of another circular tube. The bottom of each circular tube has several circumferential grooves. A connecting rod is installed within each groove, and a limiting rod is fitted onto the connecting rod. A spring is installed on the connecting rod, one end of which is connected to the inner wall of the groove, and the other end is connected to the end of the limiting rod. The sleeve has a matching insertion hole for each groove, and a top rod is slidably connected to the insertion hole. A rotating rod is hinged to the outer end of the top rod, and a slide rail is provided on the rotating rod. A support column is slidably connected to the slide rail, and the support column is mounted on the sleeve. The top of the support column and the slide rail are rotatable relative to each other. Support grooves and hanging grooves are provided on both sides of the bottom of the rotating rod. A limiting block is provided below the support column, and a limiting groove is provided on the limiting block. A fixing rod is slidably connected within the limiting groove.

[0006] The working principle of the above technical solution is as follows:

[0007] In the specific installation of this utility model's single-tube tower, the top rod inside the insertion hole is first pulled outward, and the rotating rod is slid along the slide rail at the top of the support column and its angle is adjusted. After the rotating rod angle is appropriate, the position and angle of the rotating rod are fixed by the hanging groove and the fixed rod, preventing the top rod from accidentally pushing the limiting rod and causing the locking failure. Then, a round tube is fixed on the preset foundation. Subsequently, the bottom of the upper round tube to be spliced ​​is aligned with the sleeve at the top of the lower round tube and inserted downward. During the insertion process, the limiting rod at the bottom of the upper round tube retracts along the connecting rod into the cylinder groove under the pressure of the inner wall of the sleeve, compressing the spring. When the upper round tube is inserted to the preset depth, the cylinder groove at the bottom of the round tube and the sleeve... When the upper and lower tubes are fully aligned, the spring force resets and pushes the limiting rod outward along the connecting rod, partially inserting the limiting rod into the tube, thus locking the upper and lower tubes. For disassembly, first release the fixing rod from fixing the angle of the rotating rod, move the top rod into the tube, and slide the rotating rod along the slide rail at the top of the support column, adjusting its angle so that the top rod pushes the limiting rod in the tube to overcome the spring force and fully retract into the cylinder groove. The angle of the rotating rod is fixed by the support groove and the fixed rod's support connection, thereby simultaneously releasing the locking state of the upper and lower tubes. Finally, pull the upper tube upward to remove it from the sleeve. If the entire single-tube tower needs to be disassembled, repeat the above steps to remove each section of the tube in sequence.

[0008] This invention achieves rapid splicing and locking of the round tube by using a sleeve and a spring-driven limiting rod locking mechanism. At the same time, adjustable support columns and fixing rods enhance structural stability. Disassembly only requires pushing the top rod to release the lock, making the operation simple and effectively improving the installation efficiency and maintenance flexibility of the single-tube tower.

[0009] In a further technical solution, the hanging groove is located below the support groove, and the groove of the support groove is set to face obliquely upward, while the groove of the hanging groove is set to face obliquely downward. The angle between the grooves of the support groove and the hanging groove is set to enhance the connection stability with the fixed rod, thereby strengthening the stability of fixing the position of the rotating rod.

[0010] In a further technical solution, the length of the connecting rod is less than the length of the cylindrical groove, the length of the limiting rod is less than the length of the cylindrical groove, and when the spring is in a naturally extended state, the outer end of the limiting rod extends out of the cylindrical groove port, ensuring that the limiting rod can effectively extend out of the cylindrical groove and pass through the insertion hole to achieve locking under the action of the spring, while ensuring that the limiting rod can be completely retracted into the cylindrical groove to release the lock.

[0011] In a further technical solution, the length of the push rod is greater than the depth of the insertion hole. When the push rod is fully inserted into the insertion hole, the inner end of the push rod can push the limiting rod to retract completely into the cylindrical groove, and the push rod is flush with the inner end of the insertion hole, ensuring that the push rod can fully extend into the insertion hole and push the limiting rod to retract completely, ensuring that the locking state between the round tubes can be completely released, while avoiding damage to the sleeve or round tube caused by excessive extension of the push rod.

[0012] In a further technical solution, the sliding groove on the limiting block is Z-shaped. The Z-shaped sliding groove provides multi-position limiting for the fixed rod, ensuring the stability of the fixed rod when connected to the support groove or hanging groove, and avoiding accidental sliding.

[0013] In a further technical solution, the top of the sleeve sidewall is provided with a notch corresponding to the sleeve groove. The notch can guide the limiting rod during the insertion of the round tube into the sleeve, preventing the limiting rod from being blocked by the top edge of the sleeve and ensuring that the round tube can be smoothly inserted into the sleeve to complete the splicing.

[0014] The beneficial effects of this utility model are:

[0015] 1. This utility model adopts a sleeve connection combined with a spring-driven limiting rod locking mechanism, which eliminates the need for bolt-to-hole or welding operations, enabling rapid splicing and locking of multiple round tubes. This avoids the problems of loose bolts and welding damage in traditional connection methods, and significantly improves installation efficiency.

[0016] 2. By rotating and sliding the rod along the top of the support column and limiting the angle of the fixed rod, combined with the different functions of the support groove and the hanging groove, the structure can be stably locked during installation and can be efficiently unlocked during disassembly. The operation is simple and the maintenance flexibility is improved.

[0017] 3. The design of the "Z"-shaped sliding groove and guide groove ensures precise matching of each component, enhances structural stability, and adapts to the usage requirements of different scenarios. Attached Figure Description

[0024] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0025] Example:

[0026] A type of socketed single-tube tower, such as Figures 1 to 4 As shown, the device includes several circular tubes 10. A sleeve 20 is provided at the top of each circular tube 10, and the top of the sleeve 20 is used to connect to the bottom of another circular tube 10. Several cylindrical grooves are provided circumferentially at the bottom of each circular tube 10. A connecting rod is provided within each groove, and a limiting rod 12 is sleeved on the connecting rod. A spring 11 is provided on the connecting rod; one end of the spring 11 is connected to the inner wall of the cylindrical groove, and the other end of the spring 11 is connected to the end of the limiting rod 12. The sleeve 20 has insertion holes that match the cylindrical grooves, and the insertion holes slide upwards... A top rod 21 is dynamically connected, and a rotating rod 30 is hinged to the outer end of the top rod 21. A slide rail 31 is provided on the rotating rod 30, and a support column 40 is slidably connected to the slide rail 31. The support column 40 is located on the sleeve 20, and the top of the support column 40 can rotate relative to the slide rail 31. Support grooves 33 and hanging grooves 32 are provided on both sides of the bottom of the rotating rod 30. A limiting block 50 is provided below the support column 40, and a limiting groove is provided on the limiting block 50. A fixing rod 51 is slidably connected in the limiting groove.

[0027] In the specific installation of this utility model of a single-tube tower, the top rod 21 in the insertion hole is first pulled outward, and the rotating rod 30 is slid along the slide rail 31 at the top of the support column 40 and its angle is adjusted. After the angle of the rotating rod 30 is appropriate, the position and angle of the rotating rod 30 are fixed by the hanging groove 32 and the fixed rod 51, so as to prevent the top rod 21 from accidentally pushing the limiting rod 12 and causing the locking failure. Then, a round tube 10 is fixed on the preset foundation. Then, the bottom of the upper round tube 10 to be spliced ​​is aligned with the sleeve 20 at the top of the lower round tube 10 and inserted downward. During the insertion process, the limiting rod 12 at the bottom of the upper round tube 10 is squeezed by the inner wall of the sleeve 20 and retracts along the connecting rod into the cylinder groove and compresses the spring 11. When the upper round tube 10 is inserted to the preset depth, the cylinder groove at the bottom of the round tube 10 and the sleeve 20 are closed. When the sockets on tube 10 are fully aligned, the spring 11 returns to its original position and pushes the limiting rod 12 outward along the connecting rod. Part of the limiting rod 12 is inserted into the socket, thus locking the upper and lower round tubes 10. During disassembly, first release the fixing rod 51 from fixing the angle of the rotating rod 30. Move the top rod 21 into the socket and slide the rotating rod 30 along the slide rail 31 at the top of the support column 40 and adjust its angle so that the top rod 21 pushes the limiting rod 12 in the socket to overcome the spring force of the spring 11 and fully retract into the cylinder groove. The angle of the rotating rod 30 is fixed by the support groove 33 and the fixing rod 51, thereby simultaneously releasing the locking state of the upper and lower round tubes 10. Finally, pull the upper round tube 10 upward to pull it out of the sleeve 20. If the entire single tube tower needs to be disassembled, repeat the above steps to remove each section of the round tube 10 in sequence.

[0028] This utility model achieves rapid splicing and locking of the round tube 10 by using the sleeve 20 and the round tube 10 in conjunction with the locking mechanism of the limiting rod 12 driven by the spring 11. At the same time, the adjustable support column 40 and the fixing rod 51 enhance the structural stability. When disassembling, only the top rod 21 needs to be pushed to release the lock, which is simple to operate and effectively improves the installation efficiency and maintenance flexibility of the single tube tower.

[0029] In another embodiment, the length of the push rod 21 is greater than the depth of the insertion hole. When the push rod 21 is fully inserted into the insertion hole, the inner end of the push rod 21 can push the limiting rod 12 to retract completely into the cylindrical groove, and the push rod 21 is flush with the inner end of the insertion hole. This ensures that the push rod 21 can fully extend into the insertion hole and push the limiting rod 12 to retract completely, ensuring that the locking state between the round tubes 10 can be completely released, while avoiding damage to the sleeve 20 or the round tube 10 caused by the excessive extension of the push rod 21.

[0030] In another embodiment, the length of the connecting rod is less than the length of the cylindrical groove, the length of the limiting rod 12 is less than the length of the cylindrical groove, and when the spring 11 is in a naturally extended state, the outer end of the limiting rod 12 extends out of the cylindrical groove port, ensuring that the limiting rod 12 can effectively extend out of the cylindrical groove and pass through the insertion hole to achieve locking under the action of the spring 11, while ensuring that the limiting rod 12 can be completely retracted into the cylindrical groove to release the lock.

[0031] In another embodiment, the length of the push rod 21 is greater than the depth of the insertion hole. When the push rod 21 is fully inserted into the insertion hole, the inner end of the push rod 21 can push the limiting rod 12 to retract completely into the cylindrical groove, and the push rod 21 is flush with the inner end of the insertion hole. This ensures that the push rod 21 can fully extend into the insertion hole and push the limiting rod 12 to retract completely, ensuring that the locking state between the round tubes 10 can be completely released, while avoiding damage to the sleeve 20 or the round tube 10 caused by the excessive extension of the push rod 21.

[0032] In another embodiment, the sliding groove on the limiting block 50 is Z-shaped. The Z-shaped sliding groove provides multi-position limiting for the fixed rod 51, ensuring the stability of the fixed rod 51 when connected to the support groove 33 or the hanging groove 32, and avoiding accidental sliding.

[0033] In another embodiment, the top of the side wall of the sleeve 20 is provided with a notch corresponding to the groove. The notch can guide the limiting rod 12 during the insertion of the round tube 10 into the sleeve 20, so as to prevent the limiting rod 12 from being blocked by the top edge of the sleeve 20 and thus ensure that the round tube 10 can be smoothly inserted into the sleeve 20 to complete the splicing.

[0034] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
