Description

Technical Field

[0001] The utility model relates to the field of flag-raising materials, in particular to a flag-raising hanging rod. Background Art

[0002] The currently used flag-raising hanging rods are usually single hanging rods or double hanging rods. When replacing the flag, the fixed rod of the double hanging rod is fixed to the flagpole by a rope. The flagpole-piercing rod of the double hanging rod is used for threading the flag and must be connected to the fixed flagpole with a buckle; the single rod of the single hanging rod is used for threading the flag and is connected to the flagpole hanging rope with a buckle. However, whether it is a single-rod or double-rod flagpole, after the flagpole-piercing rod is sleeved into the flag trouser of the flag, it is necessary to tightly press the flag trouser with a steel sheet on the top or bottom flag cap of the flagpole-piercing rod or with iron wire to fix the flag, and a buckle connection is required. Thus, operations such as replacing the flag are time-consuming and laborious.

[0003] Therefore, how to design a simple flag-raising hanging rod that facilitates the fixation of the flag to the flagpole-piercing rod is a technical problem to be solved. Summary of the Utility Model

[0004] In order to solve the above problems, the purpose of the present utility model is to provide a simple flag-raising hanging rod that makes operations such as replacing the flag more convenient and easier, can be operated by hand, and has stable flag socketing.

[0005] To achieve the above purpose, the present utility model adopts the following technical solutions: It includes an outer tube, a square small steel cap, an inner tube, a magnet cap, and a loop-shaped metal ring; the outer tube includes two L-shaped side plates and a back plate rotatably connected to the two side plates respectively. The two side plates and the back plate form an outer tube that is roughly square, and there is an opening for the flag to pass between the two side plates; the bottom of the outer tube is connected to the upper end surface of the square small steel cap; the inner tube is movably sleeved inside the outer tube; ferromagnetic attracting parts are provided at both the upper and lower ends of the inner tube, and the magnet cap is magnetically connected to the ferromagnetic attracting parts at both the upper and lower ends of the inner tube; a set of loop-shaped metal rings is provided at the upper and lower parts of the rear end surface of the outer tube respectively.

[0006] Further, the number of the magnet caps is 2.

[0007] Further, the outer tube is in the shape of a frustum of a cone with a narrower upper part and a wider lower part, the inner tube is in the shape of a frustum of a cone with a narrower upper part and a wider lower part, and the width dimension of the top port of the outer tube is between the diameter of the upper bottom surface and the diameter of the lower bottom surface of the inner tube

[0008] Furthermore, the outer tube is cut from a stainless steel plate and formed by pressing and folding.

[0009] Furthermore, the upper end surface of the square small steel cap and the bottom end of the outer tube are connected by welding.

[0010] Further, the width dimension of the opening of the outer tube is one-half of the diameter of the inner tube.

[0011] Further, the two side plates and the back plate are rotatably connected by a torsion spring.

[0012] The utility model has the following beneficial effects:

[0013] 1.

[0024] The following further describes the utility model in detail with reference to the drawings and specific embodiments:

[0025] As Figures 1-3As shown, the scheme includes an outer tube 1, a square steel cap 2, an inner tube 3, a magnet cap 4 and a circular metal ring 5; optimally, the inner tube 3 is slightly longer than the outer tube 1. The outer tube 1 includes two L-shaped side plates 12 and a back plate 13 rotatably connected to the two side plates 12, the two side plates 12 and the back plate 13 are assembled into a roughly square outer tube, and an opening 11 for the flag to pass through is left between the two side plates 12; the bottom of the outer tube 1 is connected to the upper end surface of the square steel cap 2; the inner tube 3 is movably sleeved in the outer tube 1; the upper and lower ends of the inner tube 3 are both provided with ferromagnetic attraction parts 31, and the magnet cap 4 is connected to the ferromagnetic attraction parts 31 of the upper and lower ends of the inner tube 3 by magnetic attraction; the rear end surface of the outer tube 1 is provided with a group of circular metal rings 5 ​​at the upper and lower ends. The above-mentioned square steel cap 2 movably supports the inner tube 3.

[0026] The number of the magnetic caps 4 is 2. The two magnetic caps 4 are magnetically connected to the ferromagnetic attraction parts 31 at the top end and the bottom end of the inner tube 3 respectively, so as to facilitate and quickly fix the flag.

[0027] The outer tube 1 is in the shape of a cone that is narrow at the top and wide at the bottom, and the inner tube 3 is in the shape of a truncated cone that is narrow at the top and wide at the bottom. The width of the top end of the outer tube 1 is between the diameter of the upper bottom surface and the diameter of the lower bottom surface of the inner tube 3. The inner tube 3 can move up and down in the outer tube 1, and the top end of the outer tube 1 can restrict the inner tube 3 to prevent the inner tube 3 from detaching from the outer tube 1.

[0028] The outer tube 1 is cut and folded from a stainless steel plate, and has high strength, is not prone to deformation, fracture or damage, and is resistant to oxidation and corrosion, thereby improving reliability.

[0029] The upper end surface of the square small steel cap 2 is connected to the bottom end of the outer tube 1 by welding, so that the position of the square small steel cap 2 inside the outer tube 1 is fixed and not easy to move, and the inner tube 3 can be better supported to improve reliability.

[0030] The width of the opening 11 of the outer tube 1 is half of the diameter of the inner tube 3. This prevents the inner tube 3 from falling out of the outer tube 1 and keeps the flag extending outward, thereby improving reliability.

[0031] In order to facilitate the installation of the flag on the outer side of the inner tube, the two side plates 12 and the back plate 13 are connected by a torsion spring. By pulling one side plate 12 outward and rotating it, the inner tube is taken out, and the flag is installed conveniently. When the side plate 12 rotates around the center of the torsion spring, the torsion spring can generate torque or rotational force to pull the side plate 12 back to the initial position, and when the inner tube 3 is put back, the side plate 12 can be pulled again.

[0032] The working principle is as follows: In the initial state, the inner tube 3 is arranged inside the outer tube 1, and there is a gap between the inner tube 3 and the outer tube 1 for the flag to pass through. When sleeving the flag, the inner tube 3 can be taken out of the outer tube 1 by pulling the side plate 12 outwards. The flag pants of the flag are sleeved outside the inner tube 3. Then, pull the side plate 12 outwards again, place the inner tube 3 inside the outer tube 1 and extend the flag outwards through the opening 11 of the outer tube 1. After that, move the inner tube 3 upwards so that the inner tube 3 is clamped at the top of the outer tube 1, and then use the magnet cap 4 to fix the flag to prevent the flag from slipping out. Finally, it is suspended by the loop metal ring 5 for using the rope, making the operation of replacing the flag and other operations of the flag more convenient and easier, which can be operated by hand, and the flag sleeving is stable, which is more conducive to the implementation of the flag replacement system.

[0033] The above description is only the specific implementation manner of the present invention, and does not limit the patent scope of the present invention. Any equivalent structural transformation made by using the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be included in the patent protection scope of the present invention by the same token.
