Technical Field
[0001] This utility model relates to the field of umbrella rib detection, specifically an umbrella rib detection device. Background Technology
[0002] As a common item in daily life, the durability of umbrellas directly affects the user experience. The umbrella ribs, as the core supporting component of the umbrella, have a fatigue strength that is one of the key factors determining the umbrella's lifespan. During use, umbrella ribs need to withstand bending stress in windy weather, and the stress on the ribs will change accordingly due to changes in wind direction. Over time, this can easily lead to the umbrella ribs breaking due to metal fatigue. Therefore, it is necessary to sample and test umbrellas before they leave the factory to test the fatigue strength of the umbrella ribs under frequent bending in complex weather conditions.
[0003] Traditional methods can only test a single rib or a few ribs sequentially, and cannot perform synchronous and efficient fatigue testing on all ribs of an umbrella at the same time. This is especially true for umbrellas with a large number of ribs, where the testing time is too long. Moreover, the number of ribs varies among different types of umbrellas, and traditional testing devices cannot be adapted to the different number of ribs or the different angles between adjacent ribs.

Two cylinders 44 and a slide block 40 are slidably connected to a slide rod 30. Lubricant can be applied between the slide rod 30 and the slide block 40 to reduce the friction between them. Two guide seats 41 are symmetrically arranged and fixed to the slide block 40. Two sliders 42 are slidably connected to the guide seats 41. Two cylinders 44 are respectively located below the two sliders 42. The sliders 42 are fixed to the upper end of the piston rod of the cylinders 44. A lower clamping plate 45 is rotatably connected between the two sliders 42. An upper clamping plate 46 is fixed to the lower clamping plate 45 by bolts. The lower clamping plate 45 and the upper clamping plate 46 cooperate to clamp the end of the umbrella rib.
[0016] Multiple circumferentially distributed support columns 22 are fixed between the circular mounting base 20 and the base 10. A vertical through slot 23 is opened at the center of the circular mounting base 20, through which the umbrella handle can pass.

[0024] Then, the cylinder 44 is controlled to reciprocate, thereby driving the slider 42 to move up and down, which in turn causes the umbrella ribs to bend up and down, thus enabling the testing of the fatigue strength of the umbrella ribs.
[0025] Furthermore, when inspecting the umbrella ribs, a corresponding number of actuation components can be installed according to the number of umbrella ribs, so that all umbrella ribs can be inspected simultaneously. The movement of the actuation components on each umbrella rib can be asynchronous, which can simulate the complex pressure situation exerted on the umbrella ribs by strong winds.
