Description

Technical Field

[0001] This utility model relates to a connecting base, specifically a tapered tube flagpole connecting base. Background Technology

[0002] Existing flagpole bases mostly use simple plug-in structures or counterweights (such as those filled with water or sand) for fixation. Plug-in structures are prone to loosening in strong winds, causing the flagpole to tip over; while counterweight bases offer improved stability, they are often bulky, difficult to move, and ineffective on hardened surfaces (such as concrete). Therefore, there is an urgent need to design a flagpole base that can adapt to different ground conditions and provide extremely high wind resistance to solve this problem. Utility Model Content

[0003] The purpose of this utility model is to provide a tapered tube flagpole connecting base to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A tapered flagpole connecting base includes a base body, the bottom of which is provided with anchor screws for fixing the entire base to the ground, the upper part of which is provided with a tapered connecting cavity for placing a flagpole, the bottom of which is provided with a tapered stabilizing member, and the side wall of the tapered connecting cavity is threaded with a plurality of pressing bolts, the inner end of which abuts against the outer surface of the tapered stabilizing member of the flagpole inserted in the connecting cavity.

[0005] As a further embodiment of this utility model: four anchor screws are provided and are evenly distributed around the bottom perimeter of the base body, and the anchor screws are expansion screws.

[0006] As a further embodiment of this utility model: the tapered stabilizing member at the bottom of the flagpole is integrally formed with the flagpole and is fixedly connected by welding.

[0007] As a further embodiment of this utility model: the number of top-pressing bolts is at least two, and they are evenly distributed along the circumference of the conical connecting cavity; bolt holes matching the number of top-pressing bolts are evenly distributed on the wall of the conical connecting cavity, and reinforcing ribs connected thereto are evenly arranged around the outer wall of the conical connecting cavity.

[0008] As a further embodiment of this utility model: the end of the top-pressing bolt is provided with a friction-enhancing washer, which is made of rubber.

[0009] As a further embodiment of this utility model: the end of the top-pressing bolt is provided with a friction-enhancing washer, which is made of engineering plastic.

[0010] As a further embodiment of this utility model, the base body is made of metal material.

[0011] As a further embodiment of this utility model, the base body has a hollow structure inside.

[0012] Compared with the prior art, the beneficial effects of this utility model are: High stability: Anchor bolts provide solid ground anchorage, and the combination of the conical surface and the locking force of the top bolts creates extremely strong wind and toppling resistance.

[0013] Wide adaptability: The anchor bolt fixing method allows it to be used on various hard surfaces, overcoming the application limitations of counterweight bases.

[0014] Easy to install: When installing the flagpole, simply insert it into the tapered connecting cavity and tighten the top bolt; the operation is simple.

[0015] Reliable structure: The mechanical principle of tapered surface fit and bolt pressing is clear, the connection is reliable, and the service life is long. Attached Figure Description

[0019] 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.

[0020] Please see Figures 1-2As an embodiment of this utility model, a tapered tube flagpole 4 connecting base includes a base body 1. The bottom of the base body 1 is provided with anchor screws 2 for fixing the entire base to the ground. The upper part of the base body 1 is provided with a tapered connecting cavity 3 for placing the flagpole 4. A tapered stabilizing member 5 is provided at the bottom of the flagpole 4. Several pressing bolts 6 are threaded onto the side wall of the connecting cavity. The inner end of each pressing bolt 6 abuts against the outer surface of the tapered stabilizing member 5 inserted into the connecting cavity. Tightening the pressing bolts 6 generates radial pressure, securing the flagpole 4 to the base body 1. Four anchor screws 2 are provided. The anchor bolts 2 are large expansion bolts, and the tapered stabilizing member 5 at the bottom of the flagpole 4 is integrally formed with the flagpole 4 or fixedly connected by welding. The number of top-pressing bolts 6 is at least two, and they are evenly distributed around the circumference of the tapered connecting cavity 3. The tapered connecting cavity 3 has bolt holes 7 that match the number of top-pressing bolts 6 evenly distributed on its wall. The outer wall of the tapered connecting cavity 3 is evenly provided with reinforcing ribs 8 connected to it. The ends of the top-pressing bolts 6 are provided with friction-increasing washers made of rubber or engineering plastic. The base body 1 is made of cast iron or metal material, and the interior is a hollow structure to reduce the overall weight.

[0021] The working principle of this utility model is as follows: The base body 1 is firmly fixed to the ground by multiple large anchor screws 2. The flagpole 4 has a conical stabilizing member 5 at its bottom, which is inserted into the conical connecting cavity 3 at the top of the base body 1. By screwing in the top-pressing bolt 6 on the side wall of the conical connecting cavity 3, its end is tightly pressed against the conical stabilizing member 5 of the flagpole 4. The huge friction and radial locking force generated by the conical surface mating are used to tightly connect the flagpole 4 and the base into one unit. This dual fixing mechanism (ground fixing by anchor screws 2 + conical surface locking by top-pressing bolt 6) greatly enhances the overall stability and wind resistance of the flagpole 4 system.

[0022] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
