Description

Technical Field

[0001] The utility model relates to a flagpole, in particular to a telescopic flagpole which is easy to use. Background Art

[0002] During some special festivals or celebrations, people will hang some flags to show their congratulations. Currently, most flags are hung on flagpoles. When many activities are held, there is no requirement for the height of the flag, so simple fixed flagpoles are generally used to hang flags.

[0003] However, as people's living standards gradually improve, they pay more attention to banquets and in many cases require the use of larger flags and certain requirements for the height of the flags. Therefore, it is necessary to use a flagpole with a certain height to hang the flag, but a higher flagpole is inconvenient to store and transport, so this type of simple fixed flagpole is obviously not suitable for hanging flags at a higher position. Therefore, for temporary activities, the flagpole structure used to hang flags at a higher position needs to be further improved. Utility Model Content

[0023] Combination Figures 1 to 4 The telescopic flagpole of the utility model which is easy to use is further described.

[0024] A telescopic flagpole that is easy to use is characterized by comprising a base 1 and a rod body 2 fixed on the base 1, wherein the rod body 2 comprises a plurality of mutually sleeved tubes and a positioning assembly 6 arranged between every two adjacent tubes.

[0025] The specific number of tubes can be set according to actual use requirements. In this embodiment, three tubes are provided, which are arranged from the inside to the outside as the first tube 21, the second tube 22 and the third tube 23. For the convenience of description of this embodiment, in this embodiment, the tube located on the inner side of each two adjacent tubes is defined as the inner tube 4, and the tube located on the outer side is defined as the outer tube 5. That is, in the first tube 21 and the second tube 22, the first tube 21 is the inner tube 4 and the second tube 22 is the outer tube 5, and in the second tube 22 and the third tube 23, the second tube 22 is the inner tube 4 and the third tube 23 is the outer tube 5.

[0026] The inner tube 4 has an inner positioning hole 41 near the lower end, and the outer tube 5 has an outer positioning hole 51 near the upper end. The positioning assembly 6 includes a positioning seat 61, a positioning sleeve 62, a plunger 63 and a spring 64. The positioning seat 61 is arranged in the inner tube 4, the positioning sleeve 62 is arranged in the positioning seat 61, the plunger 63 is movably fitted in the positioning sleeve 62, and the head 631 of the plunger 63 is docked with the inner positioning hole 41, the spring 64 is arranged between the positioning sleeve 62 and the plunger 63, and provides an outward thrust to the plunger 63, so that the head 631 of the plunger 63 is located in the inner positioning hole 41, and when the outer positioning hole 51 is docked with the inner positioning hole 41, the spring 64 pushes the head of the plunger 63 into the outer positioning hole 51.

[0027] In the structure of the positioning assembly 6, the positioning seat 61 is a cylindrical structure, and a radially extending mounting hole is provided on the circumferential side wall of the positioning seat 61. The positioning sleeve 62 is fixed in the mounting hole by a threaded connection structure.

[0028] The front inner wall of the positioning sleeve 62 has a limiting inner step, and the plunger 63 has a limiting outer step near the head. The cooperation between the limiting outer step and the limiting inner step can limit the plunger 63 from falling out of the front end of the positioning sleeve 62. A plug 621 is threadedly connected to the rear port of the positioning sleeve 62, and the plug 621 can provide support for the spring 64 and limit the spring 64 and the plunger 63 in the positioning sleeve 62.

[0029] The head of the plunger 63 is an arc end 632. When the inner positioning hole 41 is connected to the outer positioning hole 51, the arc end 632 is exposed to the outside of the outer positioning hole 51, and a guide edge 52 is provided on the inner opening of the outer positioning hole 51. Under this structure, the plunger 63 only needs to be pressed inward appropriately so that the edge position 633 of the arc end 632 corresponds to the guide edge 52, and the inner tube 4 and the outer tube can be relatively pulled, so that the head of the plunger 63 automatically shrinks inward under the guidance of the guide edge 52. In this embodiment, when the outermost side 634 of the arc end 632 of the plunger 63 is pressed to be flush with the outer wall of the outer tube 5, the edge position 633 of the arc end 632 can be connected with the guide edge 52, and the inner tube 4 and the outer tube 5 can be relatively slid. Therefore, no other tools are needed, and only manual pressing is required, which significantly improves the convenience of unlocking between the inner tube 4 and the outer tube 5. At the same time, it can also prevent the plunger 63 from being overly pressed inward and thus being separated from the inner positioning hole 41 .

[0030] A limiting ring 3 is provided near the upper end of the inner tube 4, which can be supported on the upper end wall of the outer tube 5. The outer diameter of the limiting ring 3 is larger than the inner diameter of the outer tube 5. Therefore, after the inner tube 4 shrinks a certain distance in the outer tube 5, the limiting ring 3 can abut against the upper end wall of the outer tube 5 to limit the shrinkage size of the inner tube 4 in the outer tube 5, and at the same time, it can prevent the inner tube 4 from falling out of the lower end of the outer tube 5.

[0031] In the tube body having both the limiting ring 3 and the outer positioning hole 51 , that is, on the second tube body 22 , the outer positioning hole 51 is located above the limiting ring 3 , which can prevent the inner wall of the third tube body 23 from pressing against the head of the plunger 63 in the outer positioning hole 51 of the second tube body 22 .

[0032] The outer tube 5 has a guide groove extending in the axial direction, and the inner tube 4 has a guide bar cooperating with the guide groove. The cooperation between the guide bar and the guide groove can limit the relative rotation of the two, so that when the inner tube 4 is pulled out of the outer tube 5, the inner positioning hole 41 and the outer positioning hole 51 can be effectively connected.

[0033] A positioning ring 7 for positioning the lower end of the flag is provided on the outermost tube, i.e., the third tube 23. When the flag is positioned, it is fixed by two upper and lower connecting sleeves on the same side of the flag, i.e., the upper connecting sleeve is sleeved on the upper end of the first tube 21, and the lower connecting sleeve is sleeved on the third tube 23. Meanwhile, the lower connecting sleeve is located below the positioning ring. In the case of strong wind, the lower connecting sleeve cannot be folded upward, so that the flag is always in an unfolded state.

[0034] In the structure of the base 1, the upper surface of the base 1 is provided with four positioning columns 12 extending upward, and each positioning column 12 is provided with a bolt hole 121; the bottom of the outermost tube body is provided with a connecting plate 231, and the connecting plate 231 is provided with a through hole for the positioning column 12 to pass through, and the connecting plate 231 is fixed to the base 1 after the bolts are screwed into the bolt holes 121. When the rod body 2 is installed on the base 1, it is only necessary to match the through hole on the connecting plate 231 with the positioning column 12 on the base 1 to achieve the alignment of the rod body 2 on the base 1, and then the fixing of the rod body on the base 1 can be achieved after the bolts are screwed in, which significantly improves the convenience of installing the rod body 2 on the base 1. Secondly, through the plug-in fit between the positioning column and the through hole, the stability of the installation of the rod body 2 on the base 1 can also be improved.

[0035] The upper surface of the base 1 is also provided with a plurality of connection hole groups 13 , which are distributed around the positioning column 12 . The connection hole groups can be used for inserting other component brackets on the base 1 , thereby realizing the multi-purpose function of the base 1 .

[0036] The base 1 is made of iron material, and a handle 11 is provided on the upper surface of the base 1 to facilitate the carrying of the base 1 .
