Description

Title of the invention: Parasol shaft Technical field of the invention

[0001] The present invention belongs to the technical field of parasols and relates to a parasol, in particular a pole of a parasol. Context of the invention

[0002] As an outdoor leisure device, parasols are widely used in squares, on beaches, in parks, courtyards, and other recreational areas, providing a comfortable space for people to enjoy the shade. For most existing folding parasols, a canopy is unfolded and supported by several poles, or ribs, to provide shade.

[0003] Currently, the poles, or ribs, of outdoor parasols have a fixed length that cannot be increased at will. However, in order to obtain a better shading effect outdoors, it is necessary to increase the shaded area, which requires longer poles. Furthermore, the length of the poles often determines the length of the parasol packaging, so excessively long poles lead to a significant increase in packaging and transport costs.

[0004] In view of these issues, a Chinese patent CN210726908U (patent no. 201921502175.7) entitled "Novel Automatic Folding Rod" comprises a first main rod and a tip, and a second main rod and a first fastener are articulated to the first main rod. According to the utility model, the automatic folding rod is provided with the first main rod, the second main rod, a third main rod, a fourth main rod, and a fifth main rod, where a connecting wire is articulated between the second main rod and the first fastener, a second connecting wire is articulated between the first main rod and the second fastener, and a third connecting steel wire is articulated between the third main rod and the third fastener.The automatic folding pole is a four-piece pole that takes up less space when folded for easier transport and allows for a larger, lighter canopy when unfolded. A push-in pole is inserted into an internal chamber of the tip by pressing a slider and then into a first opening, so the pole is more firmly inserted into the tip, effectively preventing it from coming out during the folding process. This parasol has poles that can be folded but have low strength, so this parasol is not suitable for use as a large outdoor parasol but only as a small, portable umbrella. Summary of the invention

[0005] An object of the present invention is to provide a parasol pole with a simple and reasonable structure and easy to assemble, which can effectively extend the pole and reduce the packaging cost.

[0006] In order to reach the object, the pole of a parasol comprises a pole having a rear end and an extension pole having two ends; in which one end of the extension pole is connected in a detachable manner to the rear end of the pole.

[0007] Preferably, the rod is a hollow tube into which the extension rod is inserted, a limiting mechanism is located inside the rod to limit the insertion of the extension rod.

[0008] Preferably, the limiting mechanism comprises, by way of non-limitation, a fitting disposed inside the rod, one end of the extension rod is inserted into the rod and is limited by the resistance against the fitting; or the limiting mechanism comprises a fastener connected to the rear end of the rod, one end of the extension rod is inserted into the rod and is limited by the resistance against the fastener; or the limiting mechanism comprises a recess located on the surface of the rear end of the rod, one end of the extension rod is inserted into the rod and is limited by the resistance against the internal side wall of the rod corresponding to the recess.

[0009] Preferably, the fitting located inside the rear end of the rod is hollow and has an open end and a closed end; the fitting has a flange at the end of the fitting, the flange has a closed end which blocks the rear end of the rod; one end of the extension rod is inserted into the fitting and the insertion of the extension rod is limited when the extension rod pushes against an internal side wall of the closed end of the fitting.

[0010] Preferably, the fastener is a rivet, a screw, or a pin extending radially through the rear end of the rod and the insertion of the end of the extension rod is limited by the fastener.

[0011] Preferably, the extension rod is made of a rigid material or an elastic material, and the elastic material includes spring steel, fiberglass, carbon fiber or plastic; and one end of the extension rod has an elastically deformable insertion section, and the other end of the extension rod is defined as a rotating end.

[0012] Preferably, the insertion section is formed by overlapping a plurality of longitudinally connected rod sections, and the other end of the rod of The extension is formed by overlapping a plurality of connected rod sections.

[0013] vertically.

[0014] Finally, the limiting mechanism is not necessarily provided in the rod. Preferably, the rod is a hollow tube so that one end of the extension rod can be inserted into it; the extension rod has a diameter greater than an internal diameter of the hollow rod, one end of the extension rod has a small diameter section to be inserted into the hollow rod, and a circular step is formed between the small diameter section and the main body of the extension rod so that the extension rod is positioned with the rear end of the rod.

[0015] Compared to the prior art, the present invention has the following advantages. The extension rod is inserted into and connected to the rod, so that the extension rod can be easily removed. During use, assembly can be carried out simply by inserting the extension rod into the rear end of the rod, thus lengthening the rod and making it very easy to use. According to the present invention, the rod has a simple and reasonable structure and is easy and quick to operate and assemble, which can significantly increase the shading area, meet the functional requirements of the product, and reduce packaging and transportation costs.
