Description

Automatic open-close type straight rib umbrella

Technical Field

The utility model relates to the technical field of umbrellas, in particular to an automatic open-close type straight rib umbrella which is used for sunshade and rain-proof straight rib umbrella controlled by a manual control key.

Background

The umbrella that people used daily is usually divided into straight rib umbrella and folding umbrella, and automatic folding umbrella's main rib can be through two or three folding, and the main umbrella pole utilizes the grafting stick of two-layer or three-layer sleeve type to realize manual button automatic expansion and folding function with the combination of spring, spring bayonet lock button and haulage rope, and its advantage is light, and is small, and the shortcoming is: because the main rib is provided with the folding joint, the windproof capability of the main rib is poor, the folding of the umbrella is complicated, and the structure is complex. The straight rib umbrella is also called a straight bar umbrella or a long handle umbrella, and the main rib and the main umbrella rod of the straight rib umbrella are kept unchanged in length when being unfolded and folded and are not folded. The prior straight rib umbrella adopts semiautomatic umbrella structure as follows: the umbrella stand is formed by hinging the inner ends of a plurality of main umbrella ribs with an upper nest ring at the upper end of a main umbrella rod, umbrella cloth is arranged on the outer side of the umbrella stand, an automatic umbrella opening mechanism is arranged on the main umbrella rod, the automatic umbrella opening mechanism mainly comprises a middle nest ring and a lower nest ring which are sleeved by a main umbrella rod in a sliding way, the main umbrella rib supporting rods and the pull rods are respectively hinged, an elastic arch piece with a key is arranged in the lower section of the main umbrella rod close to the umbrella handle, a telescopic spring for upwards pushing the umbrella stand is arranged between the middle nest ring and the lower nest ring, a lower nest sleeve is integrally arranged on the lower portion of the lower nest ring, a sliding cavity for embedding the middle nest sliding sleeve and the telescopic spring is arranged in the lower nest sleeve, and a clamping groove for limiting the elastic arch piece clamping pin is arranged on the lower portion of the lower nest sleeve, and the working principle is as follows: the folding state is that the clamping pin of the elastic bow piece is limited by the clamping groove of the lower nest sleeve, the clamping pin is retracted into the inner cavity of the main umbrella pole by pressing the key of the elastic bow piece by fingers, the lower nest sleeve is separated from the limiting, and the lower nest ring slides upwards under the pushing of the telescopic spring to jack the umbrella stand to form the unfolding state. The problems that exist are: when the umbrella is folded, two hands of an umbrella holder are required to operate simultaneously, one hand holds the umbrella handle tightly, the other hand holds the lower nest sleeve to pull towards the direction of the umbrella handle, and the elastic bow piece is clamped after the lower nest sleeve moves to the root of the umbrella handle to complete folding, so that the umbrella can be folded only by the simultaneous cooperation of the two hands. When the user holds the umbrella and takes on the vehicle or enters a building to fold the umbrella when carrying articles, the user cannot apply force with both hands, and is difficult to fold the umbrella, so that the umbrella is very inconvenient to use.
