detailed description

Referring to FIG. 1 , a sunshade adjusting device applied to a backpack folding umbrella includes a backpack frame 1 and a sunshade device 2 mounted on the backpack frame 1 . The sunshade device 2 includes left and right sides. The outer bracket, the left and right middle brackets, the left and right inner brackets, and the flexible cover covering the bracket, the backpack rack 1 is provided with a rotating expansion mechanism capable of folding and expanding the sunshade device, and the rotating expansion mechanism comprises a backpack Left and right bracket

rotation adjusting mechanisms

3, 4 on both sides of the rack, the left and right bracket

rotation adjusting mechanisms

3, 4 respectively adjust left outer, middle and inner brackets and right outer, middle and inner brackets, and each bracket rotates and adjusts The mechanism includes a fixing base 31 mounted on the backpack frame 1, a rotating member 32 of the rotating bracket, and a rotary adjustment knob 33. The outer end surface of the fixing base 31 is provided with a wedge surface or a torsion curved surface to rotate the member 32 and the knob 33. An acute angle to the vertical. Due to the existence of the oblique wedge surface, the sunshade device 2 can be continuously expanded outward during the expansion process until the maximum extent of expansion is reached, but in actual use, the sunshade device 2 expands to the maximum extent and then continues to advance. When adjusting, the range will gradually shrink and it will not be able to maintain the maximum range. Therefore, the inclined wedge surface can be designed as a torsion curved surface or a spiral curved surface, so as to ensure that the contraction state does not occur when the adjustment is continued, so that the sunshade device 2 Get a reasonable expansion. The sunshade device 2 and the specific structure of the rotary expansion mechanism has been described in detail in the utility model patent No. 201320615574.0, and will not be described herein.
