Description

Sunshade rotating mechanism

Technical Field

The utility model belongs to the technical field of the sun shade spare part, concretely relates to sun shade rotary mechanism.

Background

At present, most of common sunshade hanging umbrellas are composed of an umbrella cover, a stand column and a base. The upper end of the upright post is connected with an umbrella cover, and the lower end of the upright post is connected with the base. When in use, the base is fixed by a heavy object, the upright post is fixed on the base, and the umbrella cover is supported. After the sunshade suspended umbrella is fixed, the position of the umbrella cover cannot be changed, and when the irradiation position of sunlight is changed, the sunshade can not be effectively carried out.

Along with the development of sunshade technology, a rotary mechanism for rotating a sunshade rod of a sunshade also comes, for example, the publication number is CN101617878B, and discloses a rotary base of a hanging umbrella. This design need utilize bayonet lock customer service spring to inwards push up to relieve the engaged state of catch internal tooth and gear, its inside locking structural design is loaded down with trivial details, and each spare part assembly is complicated, and its manufacturing cost is higher relatively, and the umbrella stand needs and rotatory umbrella disk fixed mounting simultaneously, is unfavorable for the subsequent assembly transportation of product.

In addition, as the publication number CN102095059B, a 360-degree rotating mechanism of a sunshade and an assembling method thereof are disclosed, a lower disc, a middle disc and an upper disc of the mechanism are punched to be boss type embedding grooves, a first steel ball group is arranged on the outer edge of a boss surface at the top of the lower disc, and a second steel ball group is arranged on the outer edge of the bottom of the middle disc; the first steel ball group is clamped between the fluted disc and the lower disc, the second steel ball group is clamped between the lower disc and the middle disc, the upper disc, the fluted disc, the lower disc and the middle disc are connected into a whole through stamping rivets, the bottom of the lower disc is fixed on the cross tile type umbrella base through second cylinder head inner hexagonal screws, and the umbrella rod is fixedly connected with the upper disc through the first cylinder head inner hexagonal screws. The design needs an upper disc, a fluted disc and a lower disc, and in order to maintain the working strength, the upper disc, the fluted disc and the lower disc are usually manufactured by adopting metal materials, so that the weight of a body of the upper disc is larger, and the production cost is relatively higher.

In addition, for example, publication number CN204292381U discloses a rotary base for roman umbrella, rotary base includes the base body, rotary disk and running-board, the rotary disk circumference is seted up the evenly distributed tooth's socket, the base body has outstanding articulated seat radially, the running-board middle part has the articulated piece of articulated mutually with articulated seat, the front end of running-board has the embedding head that matches with the tooth's socket shape, the rear end of running-board is for the trampling portion that supplies the people to trample, be equipped with the torsional spring between articulated seat and the running-board and the torsional spring provides elasticity and makes the trend that the embedding head keeps embedding in the tooth's socket, a rotatory core that is the column passes the base body, rotatory core has the turn-ups that is located the base body bottom surface below, a plurality of bolts axial pass rotatory core and with. However, this structural design adopts pure iron to make the material preparation for guaranteeing the sturdiness, and weight is heavier to the structure is more complicated, and the cost of manufacture is higher, and the user needs the user oneself to install swivel base when using, if after installing in the mill, the transportation is very inconvenient, consequently, brings the inconvenient trouble of installation for the user.

Meanwhile, in the rotating process of the umbrella cover and the umbrella stand, the selected supporting points are usually positioned on the bottom rotating base, so that the force borne by the rotating base is relatively large, and therefore the umbrella cover and the umbrella stand are usually made of metal materials and combined with a large chassis design, and the rotating quality and the stability are ensured.

Therefore, the product of our side is optimized by adopting an upper and lower combined rotating structure, each part is synchronously optimized, and the plastic part material is adopted for replacement, so that the production cost is reduced, and the rotating quality and stability of the product are ensured.
