Problems solved by technology

[0002] Umbrella, as one of the most common tools in people's lives, is a daily utensil for sunshade and rain, avoiding people from being exposed to sunshine and rain, and bringing great convenience to people's lives. Almost everyone has an umbrella. Some umbrellas currently on the market The quality of the frame is uneven, but the quality of many umbrellas is relatively poor and the service life is short. As a big consumer and exporter of umbrellas, my country has strict quality inspection standards in some foreign trade trade. The standards and devices are in a blank state, which greatly reduces the competitiveness of international trade. Among them, the wind resistance of the umbrella is the key factor. At present, there is no standard and scientific test method and test device in the market. There are certain obstacles in research and development, and in addition, the quality inspection of the company during the factory inspection cannot make a good judgment on the wind resistance performance

Embodiment approach

[0026] As an improved specific embodiment, the tension measuring unit is arranged in the housing chamber of the casing 26, the casing 26 is disc-shaped, and the casing 26 is provided with an annular channel 27 in the circumferential direction, and the annular channel The groove 27 is provided with several positioning grooves 28 in the circumferential direction, and several of the tension measuring units are provided with connectors 29. One end of the elastic cord 7 is fixedly connected with the connectors 29, and the positioning grooves 28 are used for the fixed positioning of the connectors 29. .

[0027] When in use, the connecting piece 29 keeps protruding from the annular through groove 27. According to the umbrella stands of different specifications, the number of umbrella ribs is different. According to the umbrella ribs in different directions, adjust which positioning groove 28 the connecting piece 29 is fixed in. , which has a simple structure and relatively flexible ...
