Description

Technical Field

[0001] The utility model relates to the technical field of umbrellas, in particular to a novel umbrella capable of preventing ultraviolet rays, shading and insulating heat. Background Art

[0002] China is the first country in the world to invent the umbrella, with a history spanning at least 3,500 years. Today, umbrellas are no longer simply used for protection from wind and rain; they have become a versatile and diverse family of objects. With the advancement of science and technology and improvements in living standards, people are increasingly seeking new styles and functions, resulting in the continuous invention of new umbrella designs. Umbrellas currently available primarily include long-handled umbrellas and folding umbrellas. With the increasing variety of umbrella types and designs, the functionality of umbrellas is also evolving.

[0003] Current umbrellas generally include an umbrella frame, an umbrella cover, and a handle. There is now a type of umbrella that can protect against ultraviolet rays, that is, a layer of ultraviolet-proof coating is applied to the outer surface of the umbrella cover or a material with ultraviolet-proof coating is added to the umbrella cover. Although the above umbrella cover has a certain ultraviolet-proof effect, its effect is still not ideal. The coating on the umbrella cover is easily peeled off or aged after being exposed to the sun and rain, which greatly reduces its ability to absorb and block ultraviolet rays.

[0004] In addition, due to design defects, the joints of the existing umbrella frames are easily deformed or rusted, thereby affecting normal use.

[0005] Therefore, existing umbrella needs to be further improved. Utility Model Content

[0006] The purpose of the utility model is to overcome the deficiencies in the prior art and to provide a new umbrella with a simple structure, which can effectively protect the joints of the ribs, effectively reduce their deformation or rust, and can prevent ultraviolet rays, block light, and insulate heat.

[0007] In order to achieve the above-mentioned purpose, the present invention adopts the following scheme: a new type of umbrella that can protect against ultraviolet rays, block light and insulate heat, including a handle, an umbrella pole connected to the handle, a sliding sleeve slidably set on the umbrella pole, a positioning device for fixing the sliding sleeve, and an umbrella rib connected to the sliding sleeve. It is characterized in that it also includes a TPU composite umbrella cover supported by the umbrella ribs, and a covering protection mechanism is provided at the joint between the TPU composite umbrella cover and the umbrella ribs.

[0008] As another improvement of the new umbrella capable of protecting against ultraviolet rays, shading and insulating heat, the covering protection mechanism includes covering films arranged on both sides of the joints of the umbrella ribs, and the two covering films are connected together after wrapping the joints of the umbrella ribs.

[0009] As another improvement of the novel umbrella capable of protecting against ultraviolet rays, shading and insulating heat of the present invention, the TPU composite umbrella surface comprises an umbrella surface bottom layer and a TPU outer layer.

[0010] As another improvement of the new umbrella that can protect against ultraviolet rays, block light and insulate heat, a connecting sleeve is provided on the outer end of the umbrella rib, and a connecting hole is provided on the connecting sleeve. The outer end of the TPU composite umbrella cover is fixed in the connecting hole by needle and thread.

[0011] As another improvement of the novel umbrella capable of protecting against ultraviolet rays, shading and insulating heat of the present invention, the positioning device includes a first elastic piece arranged on the upper part of the umbrella pole and a second elastic piece arranged on the lower part of the umbrella pole.

[0012] As another improvement of the new umbrella that can protect against ultraviolet rays, block light and insulate heat of the present invention, the umbrella ribs include a mounting seat fixedly arranged on the upper part of the umbrella pole, and a plurality of main frames are hinged on the mounting seat evenly distributed along the circumferential direction. The connecting sleeve is arranged on the outer end of the main frame, and a hinge seat is provided in the middle of the main frame. A connecting frame is hinged on the hinge seat, and the outer end of the connecting frame is hinged on the sliding sleeve.

[0013] As another improvement of the novel umbrella capable of protecting against ultraviolet rays, shading and insulating heat of the utility model, the novel umbrella is a long-handled umbrella or a folding umbrella.

[0014] To sum up, the benefits of the present invention compared to the existing technology are as follows: the present invention has a simple structure, uses a TPU composite layer as the umbrella surface, has superior UV protection, light shading, heat shielding performance, and has a good waterproof effect; TPU has excellent high tension, high tensile strength, toughness and aging resistance, and is a mature environmentally friendly material. Using TPU as the outer layer can effectively increase the service life of the umbrella.

[0015] The rib joints of the present invention are provided with a covering protection mechanism, which wraps the rib joints, thereby effectively reducing the erosion of the rib joints by rainwater and reducing the chance of rust. In addition, the covering protection mechanism also plays a role in protecting the rib joints, effectively reducing the risk of deformation. BRIEF DESCRIPTION OF THE DRAWINGS
