Description

Technical Field

[0001] The present invention relates to flagpole base technology, and particularly to a foldable flagpole base.

Background Art

[0002] A flagpole base is used to fix a flagpole and make it stand vertically independently.

[0003] Many conventional flagpole bases are of a rigid structure formed by integral injection molding, and their overall shape and dimensions are fixed after manufacturing. Such a pedestal with a fixed volume occupies a large space during storage and transportation and is inconvenient to carry. In particular, it is not user-friendly in scenarios that require frequent movement and storage, such as outdoor activities, temporary gatherings, exhibitions, etc. Although the occupied space can be reduced by making the pedestal smaller, if the dimensions are too small, the support stability of the pedestal will be impaired, and the flagpole is likely to fall.

[0004] Therefore, on the premise of ensuring the support stability of the pedestal, making it possible to reduce the volume when not in use is an urgent technical problem to be solved in the technical field.

[0017] To enable those with ordinary skill in the art to better understand the technical configuration of the present invention, the present invention will be described in more detail below with reference to the drawings, as shown in Figures 1 to 4.

[0018] Example 1 This invention provides a flagpole base, which includes a base body (1), a cover plate (2), a handle (3), and a positioning groove (11).

[0019] The pedestal body (1) supports the flagpole and provides a supporting force. The pedestal body (1) includes an upper frame (101), a flexible side wall (102) and a lower frame (103). The upper frame (101) is a rigid annular member that maintains the shape of the upper end of the pedestal body (1). The lower frame (103) is a rigid annular member that is located at the bottom of the pedestal body (1) and contacts the ground. The flexible side wall (102) is made of a foldable elastic material and has an annular cross-section. The upper end of the flexible side wall (102) is connected to the upper frame (101), and the lower end is connected to the lower frame (103). Specifically, the upper frame (101), the flexible side wall (102) and the lower frame (103) may be integrally injection-molded, or may be fixed by secondary injection or adhesion. When the upper frame (101) is pressed downward, the flexible side wall (102) is bent, and the upper frame (101) and the lower frame (103) approach each other, realizing the axial compression folding of the pedestal body (1). When the upper frame (101) is pulled upward, the flexible side wall (102) extends, and the pedestal body (1) returns to the cylindrical unfolded state.

[0020] The flexible side wall (102) is added with long afterglow luminous powder (strontium aluminate-based long afterglow luminous powder) to the TPE material to exert a warning effect during night use.

[0021] The cover plate (2) is provided at the top of the pedestal body (1). The cover plate (2) can be provided by engaging with, adhering to or integrally molding with the upper frame (101). The cover plate (2) is provided with a screw hole, and the screw hole is used for connecting the handle (3). A through hole may be provided as a screw hole at the center position of the cover plate (2), or a nut structure may be protrudingly provided on the cover plate (2).

[0022] The handle (3) is held by the user and is also used as a connection carrier for the flagpole. A positioning rod (9) is provided at the bottom of the handle (3). The positioning rod (9) has an elongated rod-like structure and extends from top to bottom. A second male screw (10) is provided at the upper end (the side close to the handle (3) body) of the positioning rod (9). The second male screw (10) is screwed to the screw hole of the cover plate (2) to realize the detachable fixation of the handle (3) and the cover plate (2). The lower end of the positioning rod (9) has a smooth rod portion or a guide slope.

[0023] The positioning groove (11) is provided inside the base body (1). Specifically, the positioning groove (11) may be provided in the center of the inner bottom surface of the lower frame (103) or on an independent positioning stand connected to the lower frame (103). The positioning groove (11) is a blind hole or a through hole, and its inner diameter matches the outer diameter of the lower end of the positioning rod (9). After the positioning rod (9) passes through the screw hole in the cover plate (2), the lower end of the positioning rod (9) is inserted into the positioning groove (11). The positioning groove (11) forms a circumferential constraint on the lower end of the positioning rod (9), limiting the rotation and radial wobble of the positioning rod (9) relative to the base body (1).

[0024] When assembling the flagpole base in this embodiment, first unfold the base body (1) into a cylindrical shape. Next, pass the positioning rod (9) of the handle (3) through the screw hole in the cover plate (2) from top to bottom, and tighten the second male screw (10) to fix the handle (3) and the cover plate (2). At the same time, the lower end of the positioning rod (9) will naturally fall into the positioning groove (11). When disassembling, loosen the handle (3) in the opposite direction and remove the positioning rod (9) from the screw hole and positioning groove (11). When folding the base body (1), first remove the handle (3), and then press the upper frame (101) downwards.

[0025] In this embodiment, the fitting of the positioning rod (9) and the positioning groove (11) adds a secondary restraint in addition to the screw connection, effectively preventing circumferential wobbling caused by the force received by the handle (3) during use, and improving the overall stability of the flagpole base.

[0026] Example 2 This embodiment is basically identical to Embodiment 1, with the differences being as follows.

[0027] A screw cylinder (7) is provided at the bottom of the screw hole in the cover plate (2). The screw cylinder (7) is a hollow cylinder with an internal thread on its inner wall. The screw cylinder (7) extends downward and enters the interior of the base body (1). The upper end of the screw cylinder (7) communicates with the screw hole in the cover plate (2). The second male screw (10) is screw-connected to the internal thread of the screw cylinder (7). The screw cylinder (7) increases the screw engagement length, making the connection between the handle (3) and the cover plate (2) more robust and improving resistance to tension and torsion.

[0028] A seal ring is fitted onto the upper end of the positioning rod (9). The seal ring is an O-shaped rubber ring and is attached to the shaft of the positioning rod (9) above the second male screw (10). After the second male screw (10) is screwed into the screw hole and screw cylinder (7), the seal ring is compressed between the cover plate (2) and the positioning rod (9), sealing the gap in the screw connection and preventing external water vapor or dust from entering the base body (1), thereby extending the service life of the internal screw and positioning groove (11).

[0029] A first male thread (8) is provided at the top of the handle (3). A screw cap (5) is screwed onto the first male thread (8). The screw cap (5) has a removable cap-like structure. When the flagpole is not connected, tightening the screw cap (5) onto the top of the handle (3) protects the first male thread (8) from impact and flattens the top of the handle (3) for easier gripping. When fixing the flagpole, the screw cap (5) is removed and the female thread at the bottom of the flagpole is connected to the first male thread (8) to fix the flagpole and the handle (3).

[0030] An opening (4) is provided in the lid plate (2). The opening (4) is a through hole and can be located near the edge of the lid plate (2) or near a screw hole. When the base body (1) is unfolded and used, weight such as water is poured into the base body (1) through the opening (4) to ensure stability.

[0031] A non-slip pad (6) is provided at the bottom of the lower frame (103). The non-slip pad (6) is a thin sheet of rubber or silicone material and has a non-slip pattern on its underside. The non-slip pad (6) can be fixed to the bottom of the lower frame (103) by adhesive or embedding. When the base body (1) is placed on the ground, the non-slip pad (6) increases the frictional force with the ground, preventing the base from slipping or tipping over during use.

[0032] The operating principle of this embodiment is basically the same as that of Embodiment 1. During assembly, first the seal ring is fitted onto the positioning rod (9), then the positioning rod (9) is passed through the screw hole in the cover plate (2), and the second male screw (10) is screwed into the screw cylinder (7), and the seal ring is compressed during the tightening process. The lower end of the positioning rod (9) is inserted into the positioning groove (11). When connecting the flagpole, the screw cover (5) is removed and the bottom of the flagpole is connected to the first male screw (8).

[0033] Example 3 This embodiment is essentially identical to Embodiment 2, with the differences being as follows.

[0034] A first fold is provided at the connection point between the flexible side wall (102) and the upper frame (101), and a second fold is provided at the connection point between the flexible side wall (102) and the lower frame (103).

[0035] Specifically, the flexible sidewall (102) has a cylindrical, thin-walled structure. A circular annular groove or thin-walled region is provided at the transition connection point between the flexible sidewall (102) and the upper frame (101), and this region becomes the first fold. Similarly, a circular annular groove or thin-walled region is provided at the transition connection point between the flexible sidewall (102) and the lower frame (103), and this region becomes the second fold. The cross-sectional shapes of the first and second folds are V-shaped or U-shaped, and the flexible sidewall (102) is configured to fold preferentially at these two points when subjected to axial pressure.

[0036] When the user presses the upper frame (101) downward, the first fold bends inward (towards the axis of the base body (1)) and the second fold bends outward (away from the axis), causing the flexible side wall (102) to take on a Z-shaped folded form. If the pressing continues, the upper frame (101) gradually approaches the lower frame (103), and finally the upper frame (101) is fitted around the outer circumference of the lower frame (103), and the entire base body (1) is compressed into a flat disc shape. When unfolding, pulling the upper frame (101) upward causes the first and second folds to bend in opposite directions, and the flexible side wall (102) returns to a straight cylindrical shape.

[0037] Having described above only some embodiments of the present invention in an exemplary manner, there is no doubt that a person with ordinary skill in the art can modify the above embodiments in various ways without departing from the spirit and scope of the present invention. For this reason, the above drawings and description are essentially illustrative and should not be construed as limiting the scope of protection of the claims of the present invention.
