Description
Technical Field
The utility model relates to a daily life article, in particular to an extension rod connecting structure.
Background
Most of articles used in daily life all have the connecting rod that is used as the handle, but longer connecting rod is comparatively inconvenient in the transportation, often need make into several sections quarter butts with longer connecting rod, then connect into the stock through connected modes such as pull between the quarter butt. During the use, the stock of this kind of structure often damages in the junction, or the condition of shortening appears, for example the mop pole that the pull is linked together, and the mop pole that often can appear during the use shortens, and the mop pole becomes long when the user needs repeated stretching, and it is comparatively inconvenient to use.
Disclosure of Invention
To the above problem, the utility model aims at providing an extension rod connection structure, it can effectively improve joint strength, and is not fragile, and it is comparatively convenient to use.
In order to achieve the purpose, the utility model adopts the following technical proposal: an extension rod connecting structure comprises a first connecting rod, a second connecting rod, a connecting sleeve and a fixing pin; the link of head rod with the link of second connecting rod all wears to establish in the connecting sleeve, just the link of head rod with the link combination of second connecting rod forms connecting portion together, the fixed pin wears to establish in adapter sleeve and this connecting portion, will head rod, second connecting rod and adapter sleeve are fixed together, form the extension rod.
Furthermore, the connecting end of the first connecting rod and the connecting end of the second connecting rod both adopt a semi-cylindrical structure.
Furthermore, a semicircular groove is formed in the middle of the semi-cylindrical structure.
Furthermore, the connecting end of the first connecting rod is butted with the connecting end of the second connecting rod, and the two corresponding semicircular grooves form a circular through hole for penetrating the fixing pin.
Furthermore, round holes are respectively formed in two side walls of the middle of the connecting sleeve, and the two round holes are located on the same axis.
Further, the first connecting rod and the second connecting rod are made of wood, plastic or metal materials.
Furthermore, the connecting sleeve is made of metal materials.
Further, the fixing pin is made of wood, plastic or metal materials.
The utility model discloses owing to take above technical scheme, it has following advantage: the utility model has simple structure, convenient connection, effectively improved connection strength and uneasy damage; and the shortening caused by force application can not occur.
