DESCRIPTION OF THE EMBODIMENTS

[0028] 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.

Embodiment 1

[0029] With reference to FIGS. 1-5, the embodiment discloses a rapid assembly structure for assembling an upright post of an outdoor product, comprising the upright post, wherein the upright post includes a first upright post 1 and a second upright post 2; the rapid assembly structure further includes a sleeve assembly, wherein the sleeve assembly includes a first sleeve base 3 and a second sleeve base 4, the first sleeve base 3 is configured to install the first upright post 1 in a fitting manner, the second sleeve base 4 is configured to install the second upright post 2 in a fitting manner and the first upright post 1 is connected to the second upright post 2 by the fit of the first sleeve base 3 and the second sleeve base 4; after the first sleeve base 3 is in docking fit with the second sleeve base 4, a partial side wall in the first sleeve base 3 extends outwards and is in close fit with an inner cavity wall of the first upright post 1; in an attempt to optimize the aforesaid structure, the sleeve assembly can be used as a connecting component to rapidly assemble and install the first upright post 1 and the second upright post 2; and meanwhile, in order to optimize the design, the side wall of an expandable structure provided in the first sleeve base 3 is employed for further stable setting upon the assembly during the assembly, thus improving the connecting stability between the first upright post 1 and the second upright post 2.

[0030] In a specific structure, the first sleeve base 3 is fully embedded into an inner cavity of the first upright post 1, a maximum outside diameter of the first sleeve body 31 is greater than that of the first connecting base 32, and one end of the second upright post 2 is provided with a connecting end 21 embedded into an inner cavity on an end of the first upright post 1. The structure is employed to facilitate the connection between the first upright post 1 and the second upright post 2; and meanwhile, the connecting end is optimally provided to enable a long contact surface on a connection between the first upright post 1 and the second upright post 2, thus improving the stability of the connection part.

[0031] The first sleeve base 3 comprises a first sleeve body 31 and a first connecting base 32, and a thread groove 33 is provided in the first connecting base 32 and is a tapered structure; the second sleeve base 4 comprises a second sleeve body 41 and a second connecting base 42, a threaded end 43 is provided on the second connecting base 42 and configured to fit in with the thread groove 33, and is of a tapered shape; an internal thread is provided in the thread groove 33 and extends inwards from a port in a gradually reducing manner, an external thread is provided on the threaded end 43 and extends downwards from an upper end plane in a gradually expanding manner, the first connecting base 32 is provided with a flaring gap 34, and an outer side wall of the first connecting base 32 is provided with a plurality of stoppers 35; during the assembly, the threaded end 43 on the second connecting base 42 is docked to the thread groove 33 in the first connecting base 32; with the fit of the tapered internal and external thread structures during the assembly, the threaded end 43 rotates upwards continuously due to the tapered structure during the continuous rotation; after the thread groove 33 is continuously stressed, an outer side wall of the first connecting base 32 expands outwards continuously along the flaring gap 34, and the plurality of stoppers 35 on the outside wall of the first connecting base 32 extrude outwards continuously to fit snugly against the inner cavity wall of the first upright post 1, thus improving the overall installation stability; and moreover, in case of loosening later, the structure can be designed to continuously rotate upwards for further extrusion and stress, thus enhancing the installation stability between the first upright post 1 and the second upright post 2.

[0032] Preferably, a stop collar 44 is arranged between the second sleeve body 41 and the second connecting base 42, a stepped portion is provided between the second sleeve body 41 and the stop collar 44, the second sleeve body 41 is fully embedded into the inner cavity on the connecting end 21 and the stop collar 44 is clamped to a port of the connecting end 21; the second connecting base 42 protrudes outwards, particularly protrudes out of the port on the connecting end 21; the structure facilitates the assembly of an end part of the second upright post 2 into the second sleeve base 41, and the fit installation of the first sleeve base 3 into the inner cavity of the first upright post 1.

[0033] According to the present invention, 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 screw-thread fit; an external expansion 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-thread fit, thus improving the assembly stability and service life, and enhancing the overall operational performance.
