<p>A connector structure of a fully-automatically deploying/collapsing umbrella, comprising a central shaft consisting of at least three tubes, an outer tube (1), an intermediate tube (2), and an inner tube (3). The outer tube (1), the intermediate tube (2), and the inner tube (3) may be sequentially sleeved one over the other. The bottom end of the outer tube (1) is provided with an outer-tube connector (11), and the bottom end of the intermediate tube (2) is provided with an intermediate-tube connector (23), the length of the outer-tube connector (11) and of the intermediate-tube connector (23) being 8-12 mm. The connector structure of the present umbrella softens the sound made when deploying/collapsing the umbrella, thereby reducing noise. The central shaft of said umbrella snaps fully into place with less than 45 newtons of force.</p> |
