Abstract
Description
Technical Field
[0001] This utility model relates to the field of daily hardware products technology, specifically to a bamboo umbrella frame. Background Technology
[0002] As an everyday rain and sun protection product, the structural strength and durability of umbrellas largely depend on the material properties of the umbrella frame. Currently, the mainstream umbrella frame materials on the market mainly include carbon fiber, glass fiber reinforced plastic, high carbon steel, and aluminum alloy. These materials are widely used in mid-to-high-end umbrella products due to their high strength, elasticity, and lightweight characteristics. As consumers' requirements for portability and structural stability increase, the technological evolution of umbrella frame materials has always revolved around strength, weight, and durability.
[0003] However, existing mainstream umbrella frame materials have significant drawbacks in terms of sustainability, environmental impact, and user experience: First, carbon fiber and glass fiber reinforced plastics are difficult to degrade naturally and remain in the environment for a long time after being discarded. Moreover, their production process is energy-intensive and has high carbon emissions, which does not conform to the trend of green manufacturing. Second, metal umbrella frames are susceptible to rusting due to rainwater corrosion. To improve corrosion resistance, electroplating or spraying is often used. These surface coatings may contain harmful substances such as heavy metals, posing a risk of skin contact or release into the environment during use. In addition, umbrellas are multi-material composite structures with different materials for the canopy, frame, handle, and other components, making efficient separation and recycling extremely difficult. The vast majority of discarded umbrellas end up in landfills or incineration, and the cost of recycling and remelting metal materials is often higher than their recycling value, resulting in resource waste. Summary of the Invention
[0004] The purpose of this invention is to provide a bamboo umbrella frame to solve the problems of poor sustainability, poor environmental impact, and unsatisfactory user experience of existing umbrella frames.
[0005] To achieve this objective, the present invention adopts the following technical solution:
[0006] A bamboo umbrella rib is provided, comprising a first umbrella rib, with a first sliding sleeve provided at both ends of the first umbrella rib, a second sliding sleeve rotatably provided on the top of the first sliding sleeve, a second umbrella rib provided inside the second sliding sleeve, a third sliding sleeve provided at the bottom of the second umbrella rib, a fourth sliding sleeve rotatably provided on the third sliding sleeve, a third umbrella rib provided inside the fourth sliding sleeve, a first connecting buckle provided in the middle of the first umbrella rib, and a fourth umbrella rib rotatably provided on the first connecting buckle.
[0007] As a preferred embodiment of bamboo umbrella ribs, a second connecting buckle is provided in the middle of the second umbrella rib, and the cross-sections of both the first and second umbrella ribs are I-shaped.
[0008] As a preferred embodiment of bamboo umbrella ribs, a first hanging ear is provided on the right side of the first sliding sleeve at the top, and a second hanging ear is provided on the right side of the fourth umbrella rib.
[0009] As a preferred embodiment of bamboo umbrella ribs, the second sliding sleeve has a first hanging hole at its top and the fourth sliding sleeve has a second hanging hole at its bottom.
[0010] The beneficial effects of this utility model are as follows: the umbrella ribs are made of bamboo and have an I-shaped cross section to improve bending strength. The sliding sleeve and connecting buckle are made of bamboo and wood powder reinforced composite material injection molding. While improving the strength of use, it achieves degradable and environmentally friendly characteristics, effectively reducing the burden on the environment, while retaining the natural toughness and lightweight advantages of bamboo.
