Description

Technical Field

[0001] This utility model relates to the field of flagpole technology, specifically to a telescopic flagpole. Background Technology

[0002] Current flagpoles generally consist of a flagpole, a fixed pulley at the top of the flagpole, a rope passing through the pulley, a top ball, and a flag rope. After the flag is raised to the designated position, one end of the flag rope is looped around the flagpole to form a loop. The rope end is then passed through the loop, tightened, and the rope end is looped around the flagpole again and passed through the newly formed loop. Both ends are tightened to ensure the knot is firmly against the flagpole, ensuring the flag rope is secure. However, after prolonged use, this double-knot fixing method can still loosen, posing a risk of the flag falling. Furthermore, the existing flagpoles have separate fixing structures for the top of the flagpole and the fixed pulley, making pre-installation impossible. Each component must be installed individually on-site, which is inconvenient. Additionally, most existing telescopic flagpoles are segmented structures with a fixed length for each segment, preventing installers from fine-tuning the height from below after installation, thus failing to adapt to different usage needs. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a telescopic segmented flagpole that can solve the problems of existing double-sleeve fixing methods that may cause loosening and flag falling, and the existing flagpole top ball and flagpole top and fixed pulley are separately fixed structures, which are inconvenient to install, and the fixed length of each segment makes it impossible for installers to make fine adjustments to the height from below after the flagpole is installed, and cannot adapt to different usage needs.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: it includes several hollow cylindrical rods, a top ball, a mounting part, a fixed pulley, a hanging rope, and a hanging rope limiting part that are sequentially nested together; Among the several hollow cylindrical rods, the upper rods are sleeved together and fixed with bolts, the lower rods are fixed together by locking components, and the lower rods are telescopically adjustable in length. The sides of the bottom rods are fixed with hanging rope limiting components, and the top of the top rods are provided with mounting components. The mounting component includes an integrally formed first cover and a second cover. The first cover is sleeved on the outside of the top end of the top rod, and the second cover is located on the side of the rod. The fixed pulley is installed inside the second cover through a mounting shaft, and the mounting shaft passes through both sides of the second cover for fixation. The rope limiting component and the fixed pulley are located on the same side of the pole. The rope limiting component includes a fixed plate and arc-shaped plates located at both ends of the fixed plate. The arc-shaped plates at both ends are symmetrically arranged, and the arc-shaped plates have through holes for the rope to pass through. The fixed plate and the pole are fixedly connected by bolts. The hanging rope is arranged to pass around the fixed pulley and through the arc-shaped plate of the hanging rope limiting member; The top ball is connected to the mounting component via a screw, the bottom of which passes through the top of the mounting component and is fixed by threaded connection.

[0005] Furthermore, the connection structure between the upper rods is as follows: among the two adjacent rods that are nested together, the top of the lower rod is connected to a contraction opening, the diameter of which gradually increases from top to bottom, and an inner rod is connected to the top of the contraction opening, the diameter of which is the same as the top diameter of the contraction opening; the bottom of the upper rod is fitted onto the inner rod at the top of the lower rod, and the upper rod and the inner rod are fixed together by bolts.

[0006] Furthermore, the locking assembly includes a fixing sleeve and a locking nut. The fixing sleeve has a fixing rod, an external threaded section and an elastic plate connected in sequence. Several external threaded sections are evenly spaced on the top of the fixing rod. The external threaded sections are integrally formed with the fixing rod. An elastic plate is integrally connected to the top of each external threaded section. The locking nut is threadedly screwed into the external threaded section. The connection structure between the lower rods is as follows: in two adjacent rods that are nested together, the top of the lower rod is fitted around the outer periphery of the fixed rod, and the bottom of the upper rod is fitted inside the fixed rod. The external threaded section and the elastic plate are wrapped around the outer periphery of the upper rod. The locking nut is fitted around the outer periphery of the upper rod. The upper rod is locked and fixed by tightening the locking nut with the external threaded section.

[0007] Furthermore, the first cover is fixed to the top rod by bolts.

[0008] Furthermore, a limiting rod is integrally connected to the top of the screw, the outer diameter of the limiting rod is smaller than the outer diameter of the screw, the top ball includes an upper hemisphere and a lower hemisphere, the bottom of the lower hemisphere is sleeved on the outside of the limiting rod and supported by the top of the screw, the upper hemisphere and the lower hemisphere are spliced ​​together, a T-shaped pressure rod is inserted through the top of the upper hemisphere, and the bottom of the T-shaped pressure rod is sleeved inside the limiting rod for fixation.

[0009] With the above structure, the advantages of this utility model are as follows: the flag hanging rope passes through the two arc-shaped plates of the hanging rope limiting member. After the flag is raised to the predetermined position, the hanging rope is knotted in the space between the two arc-shaped plates to prevent the hanging rope from slipping. Combined with the double knot fixing method, the hanging rope is fixed to the flagpole body. The fixing effect of the hanging rope is good, and the flag is prevented from falling due to changes in position. The top ball is connected to the mounting component via a screw, and the fixed pulley is also connected to the mounting component. The top ball, mounting component, and fixed pulley can be pre-installed as an integral structure. After pre-installation, the mounting component can be directly connected and fixed to the flagpole. There is no need to install the components one by one on site, making installation convenient. The upper poles are fixed together with connecting bolts, while the lower poles are connected with locking components. The upper poles are fixed in length after connection, while the lower poles are adjustable in length and locked with locking components. By using different connection structures, the structure of the upper poles is ensured to be stable and will not loosen. At the same time, the installer can make fine adjustments to the height from below after the flagpole is installed to adapt to different usage needs. Attached Figure Description

[0011] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. The following embodiments can enable those skilled in the art to more fully understand this utility model, but do not limit the present utility model to the scope of the described embodiments.

[0012] This specific implementation method adopts the following technical solution: (e.g.) Figure 1 As shown, a telescopic flagpole includes several hollow cylindrical poles 1, a top ball 2, an mounting component 3, a fixed pulley 4, a hanging rope 5, and a hanging rope limiting component 6, which are sequentially connected.

[0013] In this embodiment, there are five hollow cylindrical rods 1. The upper rods 1 are sleeved together and fixed with bolts, while the lower rods 1 are fixed together by a locking assembly 7. The lower rods 1 are also adjustable in length.

[0014] The connection structure between the middle rod 1 and the two rods 1 above it is as follows: In the two adjacent rods 1 that are nested together, the top of the lower rod 1 is connected to a contraction opening 11, such as... Figure 2 As shown, the diameter of the contraction opening 11 gradually increases from top to bottom. An inner rod 12 is connected to the top of the contraction opening 11, and the diameter of the inner rod 12 is the same as the top diameter of the contraction opening 11. The bottom of the upper rod 1 is fitted onto the inner rod 12 at the top of the lower rod 1. The upper rod 1 and the inner rod 12 are fixed by bolts to achieve the connection and fixation between the two rods 1. The middle rod 1 and the two rods 1 above it are connected to a fixed length and cannot be adjusted.

[0015] like Figures 3-5 As shown, the locking assembly 7 includes a fixing sleeve 71 and a locking nut 72. The fixing sleeve 71 has a fixing rod 711, an external threaded section 712 and an elastic plate 713 connected in sequence. Several external threaded sections 712 are evenly distributed at intervals on the top of the fixing rod 711. The external threaded sections 712 are integrally formed with the fixing rod 711. The top of each external threaded section 712 is integrally connected with an elastic plate 713. The locking nut 72 is threadedly screwed into the external threaded section 712, which can lock and fix the rod body 1.

[0016] The connection structure between the middle rod 1 and the two rods 1 below it is as follows: In the two adjacent rods 1 that are nested together, the top of the lower rod 1 is fitted onto the outer periphery of the fixed rod 711 and fixed to the fixed rod 711, and the bottom of the upper rod 1 is fitted into the inside of the fixed rod 711. The external threaded section 712 and the elastic plate 713 are wrapped around the outer periphery of the upper rod 1. The upper rod 1 can slide and extend inside the fixed rod 711 to adjust its length. The locking nut 72 is fitted onto the outer periphery of the upper rod 1. The upper rod 1 can be locked and fixed by tightening the locking nut 72 with the external threaded section 712.

[0017] The top of the topmost rod 1 is equipped with a mounting piece 3, such as... Figures 6-7 As shown, the mounting component 3 includes an integrally formed first cover 31 and second cover 32. The first cover 31 is sleeved on the outside of the top end of the top rod 1 and is fixed to the top rod 1 by bolts. The second cover 32 is located on the side of the rod 1. The fixed pulley 4 is installed inside the second cover 32 through the mounting shaft and is fixed through both sides of the second cover 32.

[0018] The top ball 2 is connected to the mounting part 3 via a screw 8. The bottom of the screw 8 passes through the top of the mounting part 3 and is screwed to the mounting part 3. A limiting rod 81 is integrally connected to the top of the screw 8. The outer diameter of the limiting rod 81 is smaller than the outer diameter of the screw 8. The top ball 2 includes an upper hemisphere 21 and a lower hemisphere 22. The bottom of the lower hemisphere 22 is fitted outside the limiting rod 81 and supported by the top of the screw 8. The upper hemisphere 21 and the lower hemisphere 22 are spliced ​​together. A T-shaped pressure rod 23 passes through the top of the upper hemisphere 21. The top of the T-shaped pressure rod 23 presses the upper hemisphere 21 tightly, and the bottom of the T-shaped pressure rod 23 is fitted inside the limiting rod 81 for fixation. The upper hemisphere 21 and the lower hemisphere 22 are pressed and fixed by the T-shaped pressure rod 23.

[0019] A rope-hanging limiter 6 is fixed to the side of the bottom pole 1. The rope-hanging limiter 6 and the fixed pulley 4 are located on the same side of the flagpole. Figure 3As shown, the hanging rope limiting component 6 includes a fixed plate 61 and arc-shaped plates 62 located at both ends of the fixed plate 61. The arc-shaped plates 62 at both ends are symmetrically arranged above and below the fixed plate 61. The fixed plate 61 is fixedly connected to the pole 1 by bolts, and the arc-shaped plates 62 have through holes for the hanging rope 5 to pass through. The hanging rope 5 passes around the fixed pulley 4 and through the arc-shaped plates 62 of the hanging rope limiting component 6. The hanging rope 5 will not deviate. The hanging rope 5 passes through the through area on the side of the flag and is fixed. The movement of the hanging rope 5 drives the flag to move, so that the flag is raised to a higher position. After the flag reaches the predetermined position, the hanging rope 5 is knotted in the space between the two arc-shaped plates 62 to prevent the hanging rope 5 from slipping. Combined with the double knot fixing method, the hanging rope 5 is fixed to the pole 1 of the flagpole. The fixing effect of the hanging rope 5 is good, and the flag is prevented from falling due to position changes.

[0020] Working principle: The top ball 2 is connected to the mounting part 3 via the screw 8, and the fixed pulley 4 is also connected to the mounting part 3. The top ball 2, mounting part 3, and fixed pulley 4 can be pre-installed as an integral structure. After pre-installation, the mounting part 3 can be directly connected and fixed to the top pole 1 of the flagpole, eliminating the need to install each component individually on-site, making installation convenient. The upper poles 1 are fixed together with sleeve bolts, and the length of the upper poles 1 is fixed after connection. The lower poles 2 are connected together with locking assembly 7. The extension and retraction of the lower poles 1 are adjusted by the fixing sleeve 71 and locking nut 72 of locking assembly 7. The threaded engagement and tightening lock, along with different connection structures, ensure the structural stability of the upper pole 1 and prevent it from loosening. Simultaneously, installers can fine-tune the height from below after the flagpole is installed to adapt to different usage needs. The flag's hanging rope 5 passes through the two arc-shaped plates 62 of the hanging rope limiting piece 6. After the flag is raised to the predetermined position, the hanging rope 5 is knotted in the space between the two arc-shaped plates 62 to prevent slippage. Combined with a double-knot fixing method, the hanging rope 5 is secured to the flagpole body 1. The hanging rope 5 has a good fixing effect, preventing the flag's position from shifting and preventing it from falling.
