Description

Positioning structure for inner limiting tube of umbrella middle rod

Technical Field

The utility model relates to an umbrella middle rod inner limiting pipe positioning structure suitable for being used on an umbrella middle rod.

Background

Chinese patent document CN108851407A discloses a limit component of a folding umbrella middle rod, which comprises a first limit pipe and a second limit pipe, wherein the cross section of the first limit pipe is the same as that of the second limit pipe, and is similar to that of the umbrella middle rod main body; when first spacing pipe is established on the outer wall of stick main part in the less first umbrella of diameter, the external diameter of stick main part in the less first umbrella of diameter plus the wall thickness of first spacing pipe equals the internal diameter of stick main part in the great second umbrella of diameter adjacent with stick main part in the less first umbrella of diameter, works as when the spacing pipe of second is established on the inner wall of stick main part in the great second umbrella of diameter, the internal diameter of stick main part in the great second umbrella of diameter subtracts the wall thickness of the spacing pipe of second and equals the external diameter of stick main part in the less first umbrella of diameter. In the umbrella stick with such a stopper structure, there has been a good way to fix the first stopper tube to the outer wall of the stick main body in the first umbrella having a smaller diameter, but there is a big problem to fix the second stopper tube to the inner wall of the stick main body in the second umbrella having a larger diameter.

In the document of chinese patent 205106646U, an umbrella middle rod capable of being arbitrarily extended and positioned is disclosed, which is similar to the first and second limiting tubes in chinese patent CN108851407A, however, both the first and second limiting tubes are provided with an inward-folded ring at their ends respectively, and are fixedly connected with the end surface of the corresponding umbrella middle rod through glue, so that the first and second limiting tubes and the corresponding umbrella middle rod have a certain thickness, and the two can be bonded firmly. The first limit pipe, the second limit pipe and the corresponding thickness of the umbrella middle rod are increased, so that the umbrella middle rod is needed to be thicker on the whole, and the experience of a user is poor.

How can adopt in the present umbrella stick diameter unchangeable, can adopt first spacing pipe and the spacing pipe of second again to carry on spacingly to stick in the umbrella of adjacent two sections, and make the spacing pipe of second fix well on the inner wall of stick main part in the great second umbrella of diameter, be the problem that the trade is waited for to solve always urgently.
