Abstract

The utility model relates to a sun umbrella capable of being automatically opened, which comprises an umbrella bar (8), an umbrella frame and an umbrella tent (9), wherein the umbrella frame comprises an upper umbrella stick group (2) and a lower umbrella stick group (3). The sun umbrella is characterized in that a bottom umbrella stick group (4) is correspondingly arranged under the lower umbrella stick group (3) and is arranged in a taper radial shape of which the opening is upward, the lower end of the bottom umbrella stick group is bundled with a bottom umbrella disk (7) which is sheathed on the umbrella bar (8) to slide corresponding to the umbrella bar and is positioned under a lower umbrella disk (5), and then the upper end is hinged with the corresponding middle part of a lower umbrella stick (3). A spring (6) is also sheathed on the umbrella bar (8) between the bottom umbrella disk (7) and the lower umbrella disk (5), and the spring (6) is in an energy storage state when the sun umbrella is in a gathering state. Compared with the prior art, when the utility model is used, the lower umbrella disk and the bottom umbrella disk automatically upwards slide along the umbrella bar under the action of the restoring force of the spring, and each umbrella frame can be automatically unfolded. Therefore, the purpose of unfolding the sun umbrella is realized only by needing one action, and the sun umbrella has the advantages of labor saving, time saving and high efficiency.

Description

A kind of automatic-opening parasol

The utility model relates to a kind of parasol that is used for public arenas such as sandy beach, square, particularly a kind of automatic-opening parasol.

At the sandy beach, public leisure occasions such as square, parasol is a kind of sunshade apparatus of indispensability, existing parasol is the amplification of common en-toutcas basically, its structure is also consistent with common en-toutcas, comprise the umbrella bar, umbrella stand and umbrella paulin, umbrella stand is made of last umbrella frame group and following umbrella frame group, last umbrella frame group is the taper radial arrangement that Open Side Down, one end boundling and the upper umbrella disc that is fixed on umbrella masthead end, the umbrella paulin promptly with each on umbrella frame fix as multiple spot, following umbrella frame group is taper radial arrangement that opening makes progress and corresponding with last umbrella frame group, and its lower end is clustered in one and is enclosed within on the umbrella bar and the following umbrella disk of its slip relatively, the upper end then with corresponding last umbrella frame in the middle part of hinged.Because the height of parasol generally all is higher than people's height, be difficult to as common en-toutcas direct manually opened, therefore generally also be provided with the hand-rail type opener, shake crank and umbrella frame is opened gradually, yet the unlatching of the parasol of this structure is wasted time and energy, efficient is low by transmission mechanism.

The purpose of this utility model with regard to be to provide at above-mentioned prior art a kind of time saving and energy saving, only to need an action be automatic-opening parasol.

The purpose of this utility model is achieved in that automatic-opening parasol comprises the umbrella bar, umbrella stand and umbrella paulin, umbrella stand includes umbrella frame group and following umbrella frame group, last umbrella frame group is the taper radial arrangement that Open Side Down, the one end is clustered in the upper umbrella disc that is fixed on umbrella masthead end, the umbrella paulin be overlying on the umbrella frame group and with each on umbrella frame fix as multiple spot, following umbrella frame group is taper radial arrangement that opening makes progress and corresponding with last umbrella frame group, its lower end is clustered in one and is enclosed within on the umbrella bar and the following umbrella disk of its slip relatively, the upper end is then hinged with corresponding last umbrella frame middle part, it is characterized in that, under described umbrella frame group down, also be provided with corresponding with it end umbrella frame group, also be the taper radial arrangement that opening makes progress, its lower end is clustered in one and is enclosed within on the umbrella bar and its slip and be positioned at end umbrella disk under time umbrella disk relatively, the upper end is then hinged with corresponding following umbrella frame middle part, also be with a spring on the umbrella bar between end umbrella disk and the following umbrella disk, this spring is in energy accumulating state when umbrella is in rounding state.

Described spring is the spring of compressive state in the time of can being accumulation of energy, be the extension spring of extended state in the time of also can being accumulation of energy, the latter in this way, and then two ends should fix with following umbrella disk and end umbrella disk respectively up and down; After gathering, be convenient to collection for making parasol, can be provided with a latch by umbrella disk of the described end, and have a pin-and-hole at the correspondence position of umbrella bar, when parasol pack up folding after, described latch inserts in the pin-and-hole and umbrella disk relative umbrella bar in the end is fixed, and is in rounding state thereby keep parasol.

Compared with prior art, the utility model in use, under the restoring force effect of spring, following umbrella disk and end umbrella disk upwards slide along the umbrella bar automatically, end umbrella frame group, following umbrella frame group and go up the umbrella frame group and open gradually therefore and simultaneously, the umbrella paulin is all opened, the umbrella frame group is by descending the umbrella frame group to support, descend the umbrella frame group by umbrella disk and end umbrella frame group and support down on this moment, end umbrella frame group is then supported by end umbrella disk, and following umbrella disk and end umbrella disk then are in the high position of scope of activities on its each comfortable umbrella bar and keep motionless because of the supporting role of spring.Parachute-opening only needs an action to get final product, and is time saving and energy saving, efficient is high.
