This application claims the priority benefit of CN application serial no. 202221315608.X, filed on May 30, 2022. The entirety of the above-mentioned patent application is hereby incorporated by reference herein and made a part of this specification.
The present invention relates to the field of outdoor products, and particularly to a rapid assembly structure for assembling an upright post of an outdoor product as well as an outdoor umbrella and outdoor tent.
As people continue to pursue a higher standard of living and lifestyle, more and more people enjoy the outdoor activities. People often use outdoor products, such as outdoor tents, outdoor umbrellas and outdoor furniture, when taking a rest in urban squares and green areas, parks, seaside beaches or pools.
At present, common outdoor products, especially outdoor tents and outdoor umbrellas, usually have leg tubes, upright posts and umbrella posts, which are usually long. To reduce the package, a disassembly structure is usually used. For this reason, the publication No. CN210841818U discloses a connecting structure of upper and lower umbrella posts of a sunshade umbrella, belonging to the field of sunshade umbrellas. It solves the problem of spending high cost on connecting the upper umbrella post to the lower umbrella post of the current sunshade umbrella. The sunshade umbrella includes an upper umbrella post and a lower umbrella post, both of which are of a tubular shape; the connecting structure includes a concave-convex internal thread section formed by integrally pressing a bottom part of the upper umbrella post and a concave-convex external thread section formed by integrally pressing a top part of the lower umbrella post, and the internal and external thread sections are connected in a threaded manner to fixedly connect the upper umbrella post to the lower umbrella post in a threaded manner. Based on the connecting structure, the upper umbrella post of the sunshade umbrella is connected to the lower umbrella post thereof with a low cost.
In the aforesaid structure, the upper and lower umbrella posts are docked by rotationally pressing the internal and external thread structures of a thread stroke respectively. However, a straight screw-thread fit structure is employed to easily cause loosening during long-term use; and meanwhile the structure needs to process and form the umbrella post bodies, which results in relatively tedious production.
In view of the aforesaid problems, the present invention provides a rapid assembly structure for assembling an upright post of an outdoor product as well as an outdoor umbrella and outdoor tent. The segmental upright posts are rapidly assembled and installed by using a sleeve assembly. The rapid assembly structure features stable installation, convenient assembly and wide practicability.
The technical problem solved by the present invention may be implemented by the following technical solution:

One end of the second upright post is provided with a connecting end, and the connecting end is embedded into the inner cavity on an end of the first upright post.
A thread groove is provided in the first connecting base and is a tapered structure; the second sleeve base comprises a second sleeve body and a second connecting base, wherein the second connecting base is provided with a threaded end, and the threaded end is of a tapered shape and is configured to fit with the thread groove.
An internal thread is arranged in the thread groove, extends inwards from a port in a gradually reducing manner, and is provided with an external thread; and the external thread is provided on the threaded end and extends downwards from an upper end plane in a gradually expanding manner.
The first connecting base is provided with a flaring gap, and an outer side wall of the first connecting base is provided with a plurality of stoppers.
A stop collar is provided between the second sleeve body and the second connecting base, and a stepped portion is provided between the second sleeve body and the stop collar.
The second sleeve body is fully embedded into an inner cavity of the connecting end, a stop collar is clamped to a port on the connecting end, and the second connecting base protrudes outwards from the port on the connecting end.
An outdoor umbrella based on a rapid assembly structure for assembling an upright post, wherein the upright post is docked through a sleeve assembly, and the upright post is an umbrella post on which an umbrella cover is provided in a fitting manner.
An outdoor tent based on a rapid assembly structure for assembling an upright post, wherein the upright posts are docked through sleeve assemblies, and the upright posts are tent leg tubes on which a tent frame is provided in a fitting manner.
Compared with the prior art, the present invention has the following beneficial effects: the segmental upright post can be rapidly assembled by optimally designing and using the fit of the sleeve assembly, wherein the tapered screw-thread fit structure is preferably employed to enable the second sleeve base to flare and extrude the first sleeve base outwards during the continuous thread fit; an externally expandable structure of a side wall in the first sleeve base is employed to enable close fit between the first sleeve base and the inner cavity of the upright post after the sleeve assembly is assembled, thus improving the stability upon assembly; and meanwhile, in case of loosening later, adaptive adjustment can be implemented by an extrusion effect realized by continuous upward screw fit, thus improving the assembly stability and service life, and enhancing the overall operational performance.
The characteristics of the present invention can be clearly understood by referring to the detailed descriptions of the drawings and the following embodiments.
in which: 1. first upright post; 2. second upright post; 21. connecting end; 3. first sleeve base; 31. first sleeve body; 32. first connecting base; 33. thread groove; 34. flaring gap; 35. stopper; 4. second sleeve base; 41. second sleeve body; 42. second connecting base; 43. threaded end; 44. stop collar.
In order to make the technical means, creative features, achieved objectives and effects easy to understand, the present invention will be further elaborated by combining the specific illustration.
