A kind of leak-proof rain straight bone umbrella

Abstract

The invention discloses a rain leakage prevention straight rib umbrella. When the umbrella is opened, the upper end of an upper nest upwards butts against a second elastic lantern ring under the tension effect of an umbrella opening power compressed spring; extrusion force is generated among the upper nest, a first elastic lantern ring, a limit sleeve and the second elastic lantern ring; the protruding edge of a first cone is extruded by a first chambering portion to generate elastic deformation in the direction of an umbrella pole and is pressed together with the peripheral surface of the umbrella pole to form a first sealing surface; the protruding edge of a second cone is extruded by a second chambering portion to generate elastic deformation in the direction of the umbrella pole and is pressed together with the peripheral surface of the umbrella pole to form a second sealing surface; the first sealing surface can block leaked rain to prevent rain from flowing downwards along the umbrella rod, and the second sealing surface can do complementary blocking to thoroughly prevent rain from continuing to flow downwards along the umbrella rod. Therefore, the rain leakage prevention straight rib umbrella can effectively prevent dripped rain from continuing to flow downwards and from wetting hands and clothes, prevents rain from corroding metal parts, and is novel and reasonable in structure, and the service life is greatly prolonged.

Description

technical field [0001] The invention relates to the field of umbrellas, in particular to a rain-proof straight bone umbrella. Background technique [0002] Umbrella, as an indispensable daily necessities for people, can be roughly divided into folding umbrellas and straight bone umbrellas in terms of types. Among them, straight bone umbrellas occupy an important position in all kinds of umbrellas because of their good rain-shielding effect. [0003] The structure of the straight bone umbrella is known, such as the Chinese invention patent CN200910112684.3 discloses an environmentally friendly and easy-to-disassemble straight bone automatic umbrella, including a middle rod, an upper nest fixed on the upper end of the middle rod, and a The middle nest and the lower nest, the middle nest positioning piece arranged on the side wall of the middle rod below the upper nest and restricting the upward sliding of the middle nest, the elastic joint arranged at the lower end of the midd...

AI Technical Summary

Problems solved by technology

[0004] The aforementioned invention patent is the same as other straight bone umbrellas on the market. During actual use, rainwater will enter the underside of the umbrella surface from the gap between the umbrella surface and the umbrella pole. Especially in rainy days with heavy wind and rain, it is more likely to have rainwater leakage. If the rain falls, the leaked rainwater will always flow down along the umbrella pole, which will wet the hands and clothes holding the umbrella, which will bring a lot of inconvenience to people, and will make the umbrella pole and the passing metal parts such as the middle nest and the lower nest wet. Wet, causing the metal parts to be corroded by rain, seriously affecting the appearance and the service life of the entire umbrella
