A water-filled flagpole base for preventing tangling

Abstract

This utility model discloses an anti-tangling water-filled flagpole base, specifically relating to the field of advertising display equipment technology. It includes a base mechanism and an anti-tangling mechanism. The anti-tangling mechanism is installed on top of the base mechanism and comprises a rotating component, a fixing component, and a connecting threaded ring. The connecting threaded ring is installed on top of the rotating component, and the fixing component is placed on the side of the connecting threaded ring. Through the rotating component of the anti-tangling mechanism, when strong winds apply lateral wind pressure to the flag above the flagpole base, the flagpole, connected to the rotating component via the connecting threaded ring, will rotate due to the deep groove ball bearing in the rotating component, preventing the flag from tangling around the flagpole. Meanwhile, the planar thrust ball bearing ensures the flagpole remains stable in the axial direction after the wind pressure tightens the flag, avoiding rotational jamming caused by vertical movement.

Description

Technical Field

[0001] This utility model relates to the field of advertising display equipment technology, and more specifically, to an anti-tangling water-filled flagpole base. Background Technology

[0002] Flagpoles, as facilities for hanging flags, have a long history. From the initial simple wooden poles to modern flagpoles made of various materials and with various functions, they have important applications in many aspects of social life. As an important component of the flagpole, the flagpole base has also evolved and improved with the development of the flagpole. Early flagpole bases were relatively simple, mainly for fixing the flagpole. However, with the advancement of technology and the increasing requirements for the use of flagpoles, modern flagpole bases not only need to ensure the stability of the flagpole, but also need to have multiple functions such as waterproofing, windproofing, and corrosion resistance to adapt to the needs of flagpole bases in different environments.

[0003] A search revealed that publication number CN222207423U discloses a multifunctional pipe clamp flagpole base. This multifunctional pipe clamp flagpole base includes a flat clamp plate, a base connecting plate, a fixing nut, a flagpole base, a separating clamp plate, bolts, and a shaped nut. The flat clamp plate and the separating clamp plate each have four fixing holes at corresponding assembly positions. The bolts pass through the separating clamp plate and the flat clamp plate sequentially and are assembled with the shaped nut. The movable pipe is located between the separating clamp plate and the flat clamp plate. The planar structure of the flat clamp plate and the trapezoidal concave structure of the separating clamp plate ensure that at least three lines are in close contact with the movable pipe after the two clamp plates fix it, conforming to the three-point stability principle and ensuring the overall stability of the pipe clamp flagpole base. The inventors discovered the following problems with the existing technology during the development of this utility model:

[0004] Existing flagpole bases have many problems in actual use. When strong winds come and apply lateral wind pressure perpendicular to the flagpole axis to the flag, the base of the flagpole is prone to breakage due to the huge bending moment. Furthermore, since the base of the flagpole is usually fixed, the flag swings continuously under the action of strong winds, forming relative motion with the stationary flagpole, and then rotating and tangling around the flagpole, making it impossible for the flag to unfurl and the content on it to be clearly displayed to passersby. Moreover, most traditional flagpole bases are made of hollow bases or solid iron bases, so they are either not very effective and easy to tip over, or they are expensive and difficult to move.

[0005] Therefore, an anti-tangling water-filled flagpole base is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides an anti-tangling water-filled flagpole base to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an anti-tangle water-filled flagpole base, comprising a base mechanism and an anti-tangle mechanism, wherein the anti-tangle mechanism is installed on the top of the base mechanism, and the anti-tangle mechanism includes a rotating component, a fixing component and a connecting threaded ring, wherein the connecting threaded ring is installed on the top of the rotating component, and the fixing component is placed on the side of the connecting threaded ring.

[0008] Preferably, the base mechanism includes a connecting base, a water-filling base, and a water-filling component, with the water-filling base installed below the connecting base and the water-filling component installed on the side of the water-filling base.

[0009] Preferably, the rotating assembly includes a rotating tray, a deep groove ball bearing, and a flat thrust ball bearing, with the rotating tray mounted above the deep groove ball bearing and the flat thrust ball bearing mounted above the rotating tray.

[0010] Preferably, the fixing assembly includes a bearing seat, a limiting washer, and a positioning bolt, and the limiting washer is placed on the side of the bearing seat, and the positioning bolt is threadedly connected to the inside of the bearing seat.

[0011] Preferably, the water injection assembly includes a water injection pipe, a drain valve, and a connecting pipe, wherein the drain valve is installed on the side of the water injection pipe, and the connecting pipe is installed on the side of the drain valve away from the water injection pipe.

[0012] Preferably, the rotating tray is a centrally symmetrical circular plate, and a connecting column is welded to the bottom of the rotating tray. An annular groove is carved on the upper surface of the rotating tray. The inner ring of the deep groove ball bearing is interference-fitted with the connecting column at the bottom of the rotating tray, and the lower ball base of the planar thrust ball bearing is interference-fitted with the annular groove of the rotating tray.

[0013] Preferably, the bearing seat has a threaded hole through its upper and lower surfaces in the axial direction, and the positioning bolt locks the tooth meshing angle by tightening pressure to fix the bearing seat, and the limiting gasket is made of PTFE material and fills the internal cavity of the bearing seat.

[0014] Preferably, the water injection pipe and the drain valve are connected by threads, and the drain valve and the connecting pipe are connected by threads, and the water injection pipe and the connecting pipe are made of galvanized steel.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. Compared with the prior art, this anti-tangling water-filled flagpole base, through the rotating component of the anti-tangling mechanism, prevents the flag from tangling around the flagpole when strong winds apply lateral wind pressure to the flag above the flagpole base. The flagpole, connected to the threaded ring and the rotating component, will rotate due to the deep groove ball bearing in the rotating component. The planar thrust ball bearing will ensure the flagpole is stable in the axial direction after the wind pressure tightens the flag, avoiding rotational jamming caused by vertical movement. Furthermore, the flagpole connected to the base is designed with a threaded guide groove structure. When strong winds blow to one side of the flagpole, the airflow will apply a circumferential force in the opposite direction to the groove surface, thereby forming a rotational torque, causing the flagpole to rotate in conjunction with the deep groove ball bearing, preventing it from being broken.

[0017] 2. Compared with the prior art, this anti-tangling water-filled flagpole base injects distilled water into the base through a water-filling component, causing the center of gravity of the base to shift downward, thereby enhancing the flagpole base's anti-overturning ability. In addition, an anti-sedimentation filter screen is installed on the upper layer of the water-filled base to prevent impurities from sinking into the water and causing sediment to concentrate in a local area of ​​the base, resulting in a shift in the center of gravity and weakening the overall wind resistance stability of the flagpole base.

[0023] 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.

[0024] Example 1

[0025] As attached Figures 1 to 4 The anti-tangling water-filled flagpole base shown includes a base mechanism 1 and an anti-tangling mechanism 2. The anti-tangling mechanism 2 is installed on the top of the base mechanism 1. The anti-tangling mechanism 2 includes a rotating component 6, a fixing component 7 and a connecting threaded ring 8. The connecting threaded ring 8 is installed on the top of the rotating component 6, and the fixing component 7 is placed on the side of the connecting threaded ring 8.

[0026] The process involves the following steps: After the anti-tangling water-filled flagpole base is put into use, staff need to insert the advertising flag into the hollow steel pipe above the flagpole and secure it. Then, the water-filled flagpole base with the flag secured is placed in the desired display position, and distilled water is injected into its base mechanism 1. This causes the center of gravity of the base to shift downwards, preventing the flag from tipping over under wind pressure. When the flagpole base is placed in an area with high wind pressure, the airflow will blow the flag and flagpole. The threaded guide groove structure on the flagpole will convert the circumferential force applied by the airflow into rotational torque, causing the flagpole to rotate. This prevents the flagpole from breaking due to excessive wind force, and the flag will not tangle on the flagpole due to its rotation. During the rotation of the flagpole, the connecting threaded ring 8 will drive the rotating component 6 of the anti-tangling mechanism 2 to rotate. During this period, the fixing component 7 can prevent external dust from entering through the gap between the rotating component 6 and the base mechanism 1, thus preventing damage to the parts in the rotating component 6.

[0027] Example 2

[0028] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0029] In a preferred embodiment, the base mechanism 1 includes a connecting base 3, a water-filling base 4, and a water-filling component 5. The water-filling base 4 is installed below the connecting base 3, and the water-filling component 5 is installed on the side of the water-filling base 4.

[0030] In a preferred embodiment, the rotating assembly 6 includes a rotating tray 9, a deep groove ball bearing 10, and a flat thrust ball bearing 11. The rotating tray 9 is mounted above the deep groove ball bearing 10, and the flat thrust ball bearing 11 is mounted above the rotating tray 9.

[0031] In a preferred embodiment, the fixing component 7 includes a bearing seat 12, a limiting washer 13, and a positioning bolt 14. The limiting washer 13 is placed on the side of the bearing seat 12, and the positioning bolt 14 is threadedly connected to the inside of the bearing seat 12.

[0032] In a preferred embodiment, the water injection assembly 5 includes a water injection pipe 15, a drain valve 16, and a connecting pipe 17. The drain valve 16 is installed on the side of the water injection pipe 15, and the connecting pipe 17 is installed on the side of the drain valve 16 away from the water injection pipe 15.

[0033] In a preferred embodiment, the rotating tray 9 is a centrally symmetrical circular plate. A connecting column is welded to the bottom of the rotating tray 9, and an annular groove is carved on the upper surface of the rotating tray 9. The inner ring of the deep groove ball bearing 10 is interference-fitted with the connecting column at the bottom of the rotating tray 9, and the lower ball base of the planar thrust ball bearing 11 is interference-fitted with the annular groove of the rotating tray 9.

[0034] In a preferred embodiment, the bearing upper seat 12 has a threaded hole through its upper and lower surfaces in the axial direction. The positioning bolt 14 locks the tooth meshing angle by tightening pressure to fix the bearing upper seat 12. The limiting gasket 13 is made of PTFE material and fills the internal cavity of the bearing upper seat 12.

[0035] In a preferred embodiment, the water injection pipe 15 and the drain valve 16 are connected by threads, the drain valve 16 and the connecting pipe 17 are connected by threads, and the water injection pipe 15 and the connecting pipe 17 are made of galvanized steel.

[0036] The working process of this utility model is as follows: First, after the anti-tangling water-filled flagpole base is put into formal use, the staff needs to put the advertising flag into the hollow steel pipe at the top of the flagpole and fix the flag. Then, the water-filled flagpole base with the flag fixed is placed in the desired display position, and distilled water is injected into the water-filled base 4 of its base mechanism 1, so that the center of gravity of the base shifts downward, so that the flag will not tip over under the action of wind pressure. When the staff injects distilled water into the water-filled base 4, they need to first open the water pipe. One end of the water pipe is fixed to the faucet, and the other end of the water pipe is connected to the connecting pipe 17 of the water injection assembly 5 via a thread. At this point, the worker needs to turn the drain valve 16 to create a passage between the connecting pipe 17 and the water injection pipe 15. Then, the faucet is turned on to inject distilled water into the water injection base 4. When the highest level of the distilled water can be seen through the observation port of the water injection base 4, the worker needs to turn off the faucet immediately and turn the drain valve 16 to disconnect the connecting pipe 17 and the water injection pipe 15. Then, the water pipe is retracted. When the flagpole base is placed in an area with high wind pressure... When the airflow blows through the area, it will cause the flag and flagpole to move. The threaded guide groove structure on the flagpole will convert the circumferential force applied by the airflow into rotational torque, causing the flagpole to rotate and preventing it from breaking due to excessive wind. The flag will also not entangle with the flagpole due to its rotation. During the rotation of the flagpole, the connecting threaded ring 8 will drive the rotating component 6 of the anti-entanglement mechanism 2 to rotate. When the rotating component 6 rotates, the deep groove ball bearing 10 will drive the rotating tray 9 to rotate due to the torque transmitted by the flagpole. When the rotating tray 9 rotates, it will also drive the planar thrust ball bearing 11 to rotate. During the rotation of the planar thrust ball bearing 11, the flagpole will be kept stable in the axial direction. During this period, the bearing seat 12 of the fixed component 7 is fixed to the closed area formed by the positioning bolt 14 and the connecting base 3, and the limiting shim 13 filled inside the bearing seat 12 can prevent external dust from entering from the gap between the rotating component 6 and the base mechanism 1 without affecting the rotation of the rotating component 6. The above is the working principle of this anti-entanglement water-filled flagpole base.
