Abstract

The utility model relates to a beach umbrella. The existing large beach umbrella that an umbrella post is positioned at one side of the umbrella body has the disadvantages that the umbrella post is quick to wear, the existing large beach umbrella is not beautiful, an opening and closing mechanism is operated by people, the tension is arduous, and the umbrella post usually can not rotate. The utility model is provided with a slide way which guides a slide block to move and to be positioned on an umbrella post of the beach umbrella. An opening and closing mechanism of the beach umbrella is composed of a crank handle and a reduction gear with more than two stages, and the crank handle and the reduction gear are matched. The umbrella post is fixed on a movable plate, and the beach umbrella is a double-layer umbrella surface. The utility model has the advantages that operation is laborsaving, the umbrella surface can be an obliquity, a rotary angle can be adjusted, breeze exist below the umbrella, etc.

Description

A kind of parasols

The utility model relates to a kind of parasols, relates in particular to the large-scale parasols that a kind of umbrella post is positioned at umbrella body one side.

Existing large-scale parasols is positioned at umbrella central authorities in order to overcome the umbrella post, reduce the deficiency of effective usable floor area of umbrella, taked the umbrella post is positioned at the scheme of umbrella body one side, comprised umbrella body, umbrella post, base and opening and closing mechanism, the umbrella body is connected with the umbrella post with connecting rod by slide block.Because slide block generally is enclosed within on the umbrella post, the quick abrasion of umbrella post influences the attractive in appearance of umbrella post, increases the friction of slide block and umbrella post; The direct personnel selection of the stay cord of opening and closing mechanism pulls moving, because slide block and the frictional force of umbrella post and the gravity of umbrella body, very effort; The umbrella post is normally fixed, and has influenced shaded effects.

The purpose of this utility model provide a kind of opening and closing easy to operate, laborsaving, can adjust umbrella body sunshade angle and sunshade position, the umbrella post is positioned at the parasols of umbrella body one side.

The utility model is by the following technical solutions:

Parasols comprises umbrella body, umbrella post, base and opening and closing mechanism, the umbrella body is connected with the umbrella post with connecting rod by slide block, it is characterized in that on the umbrella post, having the chute that makes slide block move and locate therein, opening and closing mechanism is made up of stay cord and rocking handle, the umbrella post is fixed on the portable plate, and the fixed head on portable plate and the base flexibly connects; The umbrella post is provided with the slide block detent mechanism of being made up of locating hole and alignment pin, and the rope hauling device of opening and closing mechanism is made of crank handle and the reduction gearing more than the secondary, and stay cord one end is fixed on the low-speed gear axle; Portable plate has bottom lining plate, and the each interval fixed head connects, and the junction of portable plate, bottom lining plate and fixed head is respectively equipped with the cannelure that can insert ball; The umbrella body is a double-decker, is provided with on main umbrella surface from umbrella cover, and there is air vent at the main umbrella surface middle part, and its size is with corresponding from umbrella cover.

But the utlity model has rapid operation, umbrella cover inclination angle, advantages such as corner is adjustable, gentle breeze is arranged under the umbrella, anti-inclination.

Be described further below in conjunction with accompanying drawing.

Fig. 1 is an overall construction drawing of the present utility model;

Fig. 2 is the utility model chute profile;

Fig. 3 is the utility model rocking handle cut-away view;

Fig. 4 is the utility model base cut-away view.

As Fig. 2, Fig. 3, utility model embodiment chute cut-away view shown in Figure 4, chute is in umbrella post inner surface, and is relative less with extraneous dust storm contact, helps preventing corroding, and keeps lubricated;

Open-and-close mechanism drives pinion by crank handle, and pinion drives gear wheel, and stay cord is fixed in Large Gear Shaft During, and is very laborsaving.Portable plate that links to each other with the umbrella post and bottom lining plate are clamped the fixed head on the base.

When needs are opened parasols, rotate crank handle (11) and tighten up stay cord (6), slide block (2) when upwards being dragged to a certain locating hole, is plugged fixedly slide block of alignment pin by stay cord (6), is rotated further crank handle (11) and opens whole umbrella cover.

When needs are adjusted the rotational angle of umbrella, in the through hole on the bolt that connects portable plate (12) and bottom lining plate (14) on the pin insertion base, rotating bolt makes portable plate (12), bottom lining plate (14) reduce the chucking power of fixed head (13), frictional force reduces, can rotate portable plate (12) and bottom lining plate (14), drive the corresponding rotation of umbrella post (1).

When needs are adjusted parasols umbrella cover angle, change the position that slide block (2) is located in umbrella post chute, the angle of inclination that can drag whole umbrella body changes, and changes parasols umbrella cover angle.
