Technical Field

The utility model relates to the technical field of articles for daily use, especially, relate to an umbrella that ability convenience of customers changed umbrella body part.

Background

The umbrella, as a tool used by people in daily life, protects people from rain and sunshine, has become a necessary daily necessity for people. Typically parasols or umbrellas are assembled and shipped as a complete unit in a factory. If one or several main ribs or sub-ribs are damaged or broken, since a general sunshade or umbrella is sold as a complete and non-detachable unit, it is impossible for a user to replace only the damaged main ribs or sub-ribs for repair, so that the user is forced to discard the whole sunshade, which is very wasteful and uneconomical for the consumers, and thus further improvement of the existing umbrellas is required.

SUMMERY OF THE UTILITY MODEL

The technical problem to be solved in the utility model is to provide an umbrella that can be convenient for the user to change umbrella body part to above-mentioned prior art current situation.

The utility model provides a technical scheme that above-mentioned technical problem adopted does: the umbrella comprises a main shaft and is characterized in that: also includes:

an upper connecting seat mounted on an upper shaft portion of the main shaft;

the main umbrella rib group comprises at least two main umbrella ribs arranged along the circumferential direction of the main shaft at intervals, the inner end part of each main umbrella rib is detachably pivoted on the upper connecting seat, and the tail end part of each main umbrella rib is detachably connected with the tip component of the outer circumferential part of the umbrella cloth;

the lower connecting seat is movably arranged on the lower shaft part of the main shaft; and

the supporting umbrella rib group comprises at least two supporting umbrella ribs arranged along the circumferential direction of the main shaft at intervals, the upper end of each supporting umbrella rib is pivoted to the middle part of the corresponding main umbrella rib, and the lower end of each supporting umbrella rib is detachably pivoted to the lower connecting seat; therefore, the umbrella can be opened or closed under the condition that the lower connecting seat slides up and down relative to the main shaft.
