Embodiment Construction

[0019] Below in conjunction with the best embodiment shown in the accompanying drawings, it will be further described in detail.

[0020] The present invention can be applied to both straight-bone umbrellas and multi-fold umbrellas.

[0021] Take the straight bone umbrella as an example, such as image 3 As shown, the automatic umbrella framework of the present invention which is developed and retracted smoothly comprises: rod 1 in the umbrella, upper nest 2, middle nest 31, lower nest 32, main bone 8, support bone 5 pull rod 6 and umbrella opening spring 7. Wherein, the upper nest 2 is fixed on the top of the umbrella rod 1, and the middle nest 31 and the lower nest 32 are slidably sleeved on the umbrella rod 1 and fixedly connected between the two, so that the middle nest 31 and the lower nest 32 The distance between them is fixed. The main bone 8 is used to support the umbrella surface, and its inner end is pivotally connected with the upper nest 2 . The inner end of the...

Abstract

The invention discloses an automatic umbrella framework capable of being opened and closed smoothly. The automatic umbrella framework comprises a main bone (8) of which the inner end is pivoted with an upper nest (2) to support an umbrella cover, a supporting bone (5) of which the inner end is pivoted with a middle nest (31), a pull rod (6) of which the inner end and the outer end are respectively connected with a lower nest (32) and the supporting bone (5), and an umbrella opening spring (7), wherein a lantern ring (61) is arranged at the outer end of the pull rod (6), and is sleeved on the supporting bone (5) in a sliding mode; the umbrella opening spring (7) is sleeved on the supporting bone (5) and is clamped between the lantern ring (61) and the middle nest (31); and the middle nest (31) is fixedly connected with the lower nest (32). The automatic umbrella framework capable of being opened and closed smoothly adopts a new umbrella opening spring structure, so that an umbrella can be opened and closed very smoothly; and the automatic umbrella framework capable of being opened and closed smoothly is simple to assemble, beautiful in appearance, small in umbrella closed size, and suitable for straight bone umbrellas or multi-folding umbrellas.

Description

technical field [0001] The invention relates to a sun umbrella, in particular to an improvement of an automatic umbrella skeleton opening structure. Background technique [0002] Existing automatic umbrellas, such as figure 1 The tension spring type automatic umbrella shown is usually provided with a tension spring 3' at the outer end of the pull rod 6' connected to the support bone 5', and the tension of the tension spring 3' keeps the nest under the umbrella in a sliding trend to realize the umbrella opening the goal of. But when the rivet that connects extension spring 3 ' and support bone 5 ' of this automatic umbrella falls off, or extension spring 3 ' and pull bar 6 ' junction falls off, extension spring 3 ' can rebound and hurt the user, so there is a big problem. security risks. [0003] For this reason the applicant discloses a kind of automatic umbrella skeleton in the Chinese invention patent that application number is 200720122228.3, and its umbrella opening s...
