Description

The improvement structure of umbrella frame

The utility model relates to a kind of improvement structure of umbrella frame, relates in particular to a kind of improved structure of automatic umbrella rib.

Umbrella is daily one of the indispensable tool usings of going out of people, and modern's commercial activity is frequent, and life is progressive, all are stressed conveniently, use automatic umbrella no exception, but automatically the fault rate of umbrella is quite high, through looking into its reason nothing more than being that umbrella frame uses due to the impact of automatic tension spring.Now consult Fig. 4 and it is described with regard to the structure of commonly using automatic umbrella.Generally speaking, umbrella mainly comprises a middle axostylus axostyle 100 together with handle, nest 103 during the following nest 101 that can slide on middle axostylus axostyle reaches, be located at down, tension spring 102 between middle nest, last nest 104, main umbrella skeleton 105, supporting umbrella bone 106, pull bar 108 grades constitute, because strutting automatically of unfurling an umbrella automatically is set tension spring 102 between nest and following nest in the mat, when stretching to latter end by this spring 102, the impulsive force of upholding is quite big, and the pivot joint tip of 108 on supporting umbrella bone and pull bar nail 109 is very little, simultaneously general supporting umbrella bone 106 is to become U-lag by the iron sheet punching out, in order to alleviate the weight of umbrella, generally all use thin material iron sheet punch forming, so under the impact forces that umbrella struts, one uses one period time to umbrella, even after very short time, this pivot joint tip nail 109 is owing to be to adopt riveted and fixed, be easy to separate with supporting umbrella bone and generate fault once getting rusty, though miscellaneous part still belong to new product and scrap and can not re-use, unfortunate really.

The applicant has mirror and this, long-pending be engaged in umbrella and make and sell the experience that reaches more than two decades, to the above-mentioned shortcoming that unfurls an umbrella automatically of commonly using, is improved and a kind of improvement structure of umbrella frame of automatic umbrella is provided.

Therefore the purpose of this utility model is to provide a kind of improvement structure of umbrella frame, makes the articulated section non-corrosive between supporting umbrella bone and pull bar and does not gain in weight down, and give enough tensile strength, to increase the service life of automatic umbrella.

A time purpose of the present utility model is to provide a kind of improvement structure of umbrella frame, and its supporting umbrella bone is to adopt to hook together combine not use any facility riveting job with articulated part between pull bar, so that installation exercise makes things convenient for is quick again, can significantly reduce production costs.

Above-mentioned and other purpose of the present utility model, effect and feature high-ranking officer are more clear with the specific embodiment of accompanying drawing.
