Description

Technical Field

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

[0002] Single-tube towers, with their compact structure, small footprint, and strong adaptability to the surrounding environment, are widely used in communication base station construction, urban monitoring poles, and lighting towers. Currently, the assembly methods for single-tube towers mainly suffer from two problems: First, traditional single-tube towers using flange connections require welding flanges to the ends of each tower section and securing them with dozens of bolts. This not only increases the weight and manufacturing cost of the tower but also requires multiple people to align the bolt holes and tighten the bolts during on-site installation, which is time-consuming and labor-intensive, severely impacting construction efficiency. Second, existing plug-in single-tube towers mostly use simple bayonet or pin positioning. While this simplifies the installation process, the stability of the connection points is insufficient. They are prone to circumferential rotation or axial loosening under the influence of wind, vibration, and other external forces, posing safety hazards. Therefore, there is an urgent need for a single-tube tower structure that is easy to install and has a stable connection. Utility Model Content

[0003] To address the aforementioned issues, this invention provides a plug-in single-tube tower. Through the plug-in connection and rotation locking structure between the round tubes, the single-tube tower can be quickly assembled while ensuring the structural strength and stability of the connection parts, thus reducing installation difficulty and maintenance costs.

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

[0005] A plug-in single-tube tower includes a first circular tube and a second circular tube. An inner tube is rotatably connected to the top inner cavity of the first circular tube. A ring is provided at the bottom of the inner tube. An annular groove adapted to the ring is formed on the inner wall of the top inner cavity of the first circular tube. The ring is engaged in the annular groove and can rotate circumferentially. The top of the inner tube extends to the outside of the first circular tube, and multiple fan-shaped limiting blocks are uniformly fixedly connected to it circumferentially. A rotating wheel is fixedly connected to the outer side of the inner tube between the first circular tube and the limiting blocks. A sliding groove matching the horizontal cross-sectional shape of the limiting blocks is formed in the axial direction of the bottom inner cavity of the second circular tube. A receiving groove communicating laterally with the sliding groove is also formed on the inner wall of the bottom inner cavity of the second circular tube.

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

[0007] During installation, the inner tube of the plug-in single-tube tower of this utility model is first adjusted to its initial state, so that the limiting block at the top of the inner tube is aligned with the sliding groove at the bottom of the second round tube. The sliding groove is then inserted downwards along the axial direction. When the fan-shaped limiting block is completely slid into the top of the sliding groove, the top of the inner tube is exactly level with the height of the receiving groove. Then, the rotating wheel on the inner tube is rotated, and the rotating wheel drives the inner tube and the limiting block to rotate synchronously around the axis of the inner tube, so that the limiting block moves from the sliding groove into the horizontally connected receiving groove. At this time, the two round tubes are locked by the snap-fit ​​between the limiting block and the receiving groove. The whole process does not require complicated bolt alignment and tightening operations. The quick connection between the round tubes can be achieved by plugging and rotating.

[0008] This utility model simplifies the installation process of a single-tube tower by using a rotating connection structure between the inner tube and the round tube, combined with the plug-in locking design of the limiting block, slide, and receiving groove. It also ensures the structural stability of the connection parts and is suitable for the construction needs of single-tube towers of different heights.

[0009] In a further technical solution, a support ring is fitted over the inner tube above the rotating wheel. Multiple connecting rods are provided between the support ring and the top of the first round tube. An arc-shaped groove is provided on the rotating wheel for the connecting rods to pass through. The central angle of the arc-shaped groove allows the limiting block to rotate completely into and out of the receiving groove. The support ring can prevent the bottom of the inserted round tube from directly contacting the rotating wheel, preventing the gravity or friction of the second round tube from affecting the rotation of the rotating wheel, and ensuring the smoothness of the inner tube adjustment.

[0010] In a further technical solution, a limiting rod is slidably provided in the inner cavity of the slide groove, and a circular groove is provided on the support ring along the circumferential direction. After the limiting block enters the receiving groove, it pushes the limiting rod to slide down along the slide groove, so that the top of the limiting rod is inserted into the circular groove. The limiting rod and the circular groove cooperate to fix the position of the limiting block in the receiving groove and prevent it from shifting due to external force.

[0011] In a further technical solution, a movable groove is provided on the bottom wall of the second circular tube corresponding to the position of the limiting rod. A movable block is fixedly connected to the top of the limiting rod. The movable block passes through the movable groove and can slide along the extension direction of the movable groove. The operator can drive the limiting rod to slide along the groove by moving the movable block on the outside of the circular tube.

[0012] In a further technical solution, the length of the inner tube above the support ring is equal to the length from the receiving groove to the bottom of the round tube, ensuring that when the two round tubes are joined together, the support ring just abuts against the bottom of the round tube.

[0013] In a further technical solution, the length of the limiting rod is greater than the length of the sliding groove and the circular groove, which can ensure that the limiting rod can be fully inserted into the circular groove to achieve effective locking, and can also remain within the constraint range of the sliding groove and the moving groove during the sliding process, thus ensuring the stability of the structure.

[0014] In a further technical solution, at least one rotating rod is fixedly connected to the rotating wheel, and the operator can easily drive the rotating wheel and the inner tube to rotate by rotating the rod without the need for additional tools.

[0015] The beneficial effects of this utility model are:

[0016] 1. This utility model greatly simplifies the installation process of a single-tube tower by using the insertion and connection of the limiting block with the sliding groove and the receiving groove, combined with the rotation locking structure of the inner tube. It eliminates the need for complicated bolt alignment and tightening operations, improves assembly efficiency, and reduces the risk of high-altitude operations.

[0017] 2. The design of the support ring effectively avoids direct contact between the upper round tube and the rotating wheel, ensuring smooth rotation and adjustment of the inner tube;

[0018] 3. With the help of the secondary locking design of the limit rod and the circular groove, combined with the convenient operation structure of the rotating rod and the moving block, the stability of the circular tube connection is strengthened, preventing loosening during long-term use, and facilitating disassembly and adjustment during later maintenance.

[0026] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0027] Example:

[0028] A plug-in single-tube tower, such as Figure 1 and Figure 2 As shown, the device includes a first circular tube 10 and a second circular tube 11. The top inner cavity of the first circular tube 10 is rotatably connected to an inner tube 20. The bottom of the inner tube 20 is provided with a ring. The inner wall of the top inner cavity of the first circular tube 10 is provided with a ring groove that matches the ring. The ring is engaged in the ring groove and can rotate around it. The top of the inner tube 20 extends to the outside of the first circular tube 10, and multiple fan-shaped limiting blocks 21 are uniformly fixedly connected to it around the circumference. A rotating wheel 22 is fixedly connected to the outer side of the inner tube 20 between the first circular tube 10 and the limiting blocks 21. The bottom inner cavity of the second circular tube 11 is provided with a sliding groove 30 that matches the horizontal cross-sectional shape of the limiting block 21 along the axial direction. The inner wall of the bottom inner cavity of the second circular tube 11 is also provided with a receiving groove 31 that communicates laterally with the sliding groove 30.

[0029] During installation, the inner tube 20 inside the first circular tube 10 is first adjusted to its initial state, so that the limiting block 21 at the top of the inner tube 20 is aligned with the sliding groove 30 at the bottom of the second circular tube 11. The sliding groove 30 is then inserted downwards along the axial direction. When the fan-shaped limiting block 21 is completely slid into the top of the sliding groove 30, the top of the inner tube 20 is exactly level with the height of the receiving groove 31. Then, the rotating wheel 22 on the inner tube 20 is rotated. The rotating wheel 22 drives the inner tube 20 and the limiting block 21 to rotate synchronously around the axis of the inner tube 20, so that the limiting block 21 rotates from the sliding groove 30 into the horizontally connected receiving groove 31. At this time, the two circular tubes are locked by the snap-fit ​​between the limiting block 21 and the receiving groove 31. The whole process does not require complicated bolt alignment and tightening operations. The quick connection between the circular tubes can be achieved by plugging and rotating.

[0030] This utility model simplifies the installation process of a single-tube tower by using a rotating connection structure between the inner tube 20 and the round tube, combined with the plug-in locking design of the limiting block 21, the sliding groove 30, and the receiving groove 31. It also improves the assembly efficiency and ensures the structural stability of the connection parts, making it suitable for the construction needs of single-tube towers of different heights.

[0031] In this embodiment, the top of the first circular tube 10 is composed of a fixed arc-shaped tube and a detachable arc-shaped tube. The fixed arc-shaped tube and the main body of the first circular tube 10 are integrally formed. The inner wall of the inner cavity of the fixed arc-shaped tube and the inner wall of the detachable arc-shaped tube are both provided with semi-annular grooves. After the two are spliced ​​together, they can be combined to form a complete annular groove. During assembly, the ring is first placed on the semi-annular groove of the fixed arc-shaped tube, and then the mating surfaces of the detachable arc-shaped tube and the fixed arc-shaped tube are aligned and welded to complete the assembly of the inner tube 20 and the first circular tube 10. At this time, the fixed arc-shaped tube and the detachable arc-shaped tube are spliced ​​together to form a complete circular tube top structure, and the ring is completely embedded in the spliced ​​annular groove.

[0032] In another embodiment, such as Figure 3 and Figure 4 As shown, the inner tube 20 is fitted with a support ring 24 above the rotating wheel 22. Multiple connecting rods 26 are provided between the support ring 24 and the top of the first round tube 10. The rotating wheel 22 has an arc-shaped groove 27 for the connecting rods 26 to pass through. The central angle of the arc-shaped groove 27 allows the limiting block 21 to rotate completely into and out of the receiving groove 31. The support ring 24 can prevent the bottom of the inserted round tube from directly contacting the rotating wheel 22, and prevent the gravity or friction of the second round tube 11 from affecting the rotation of the rotating wheel 22, thus ensuring the smooth adjustment of the inner tube 20.

[0033] In another embodiment, such as Figure 5 As shown, a limiting rod 32 is also slidably provided in the inner cavity of the slide groove 30, and a circular groove 25 is provided on the support ring 24 along the circumferential direction. After the limiting block 21 enters the receiving groove 31, it pushes the limiting rod 32 to slide down along the slide groove 30, so that the top of the limiting rod 32 is inserted into the circular groove 25. The limiting rod 32 and the circular groove 25 are used to fix the position of the limiting block 21 in the receiving groove 31, preventing it from shifting due to external force.

[0034] In another embodiment, a moving groove 33 is provided on the bottom wall of the second circular tube 11 at the position corresponding to the limiting rod 32. A moving block 34 is fixedly connected to the top of the limiting rod 32. The moving block 34 passes through the moving groove 33 and can slide along the extension direction of the moving groove 33. By moving the moving block 34 on the outside of the circular tube, the operator can drive the limiting rod 32 to slide along the slide groove 30.

[0035] In another embodiment, the length of the inner tube 20 above the support ring 24 is equal to the length of the receiving groove 31 to the bottom of the round tube, ensuring that when the two round tubes are joined together, the support ring 24 just abuts against the bottom of the round tube.

[0036] In another embodiment, the length of the limiting rod 32 is greater than the length of the slide groove 30 and the circular groove 25, which can ensure that the limiting rod 32 can be fully inserted into the circular groove 25 to achieve effective locking, and can not break away from the constraint range of the slide groove 30 and the moving groove 33 during the sliding process, thus ensuring the stability of the structure.

[0037] In another embodiment, at least one rotating rod 23 is fixedly connected to the rotating wheel 22. The operator can easily drive the rotating wheel 22 and the inner tube 20 to rotate by rotating the rod 23 without the need for additional tools.

[0038] 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.
