Umbrella inspection requirements and methods

Umbrella is a kind of portable tool used for shading and blocking rain, which is widely used in daily life, business trips and tourism activities. It is mainly composed of umbrella surface, umbrella bone, umbrella handle, common umbrella surface materials include touch cloth, PG cloth, etc., with good waterproof performance; umbrella bone is mostly made of stainless steel, aluminum alloy, or fiber materials, to provide stable support. According to the use of scenarios and functional differences, umbrellas can be divided into long-handled umbrellas, folding umbrellas, automatic umbrellas and other types, of which the long-handled umbrellas are stable and suitable for use in inclement weather; folding umbrellas are compact and portable, easy to carry; automatic umbrellas are known for their convenient operation. With the upgrading of consumer demand, umbrellas with special features such as windproof, sunscreen, luminous, etc. have gradually become the new favorite in the market.

The material quality of the umbrella is the basis of its quality. Umbrella materials need to have good waterproof, abrasion resistance and tear resistance. Commonly used umbrella materials, such as touch cloth, PG cloth, etc., should pass professional waterproof test to ensure that they do not leak under the impact of rain; at the same time, the color fastness of the material is examined to prevent the color from dropping out after a long time of use or exposure to water. As the supporting structure of the umbrella, the material and strength of the umbrella bone determines the durability and windproof performance of the umbrella. Whether the umbrella bone is made of stainless steel, aluminum alloy or fiber, it is necessary to check whether the surface is smooth and burr-free, whether there is any crack or deformation, and it is necessary to carry out a load-bearing test to ensure that it will not be easily broken under normal use.

Reasonable structural design can enhance the convenience and safety of umbrella use. The connection between the umbrella bone and the umbrella surface should be firm, and the stitching should be tight and even, and there should be no disconnection or loosening. The connection between the umbrella handle and the umbrella bone should be firm to avoid disconnection in the process of opening and closing. In addition, the automatic umbrella spring, button and other components should be sensitive and reliable, to ensure that the umbrella can be opened and closed smoothly, and there will be no hand pinching and other safety hazards.

The appearance of the umbrella directly affects the consumer's desire to buy. Umbrella pattern printing should be clear, colorful, no ghosting, blurring and other problems; umbrella surface should be flat, no wrinkles, stains. Umbrella bone, umbrella handle and other parts of the surface treatment should be fine, plating parts need to be bright without rust, plastic parts without scratches, bubbles and other defects.

​

Appearance inspection adopts the combination of visual and touch. The inspection personnel need to be in sufficient light conditions, carefully observe the umbrella surface, umbrella bone, umbrella handle and other parts of the appearance of the quality, check the pattern printing, color, surface treatment and so on whether it meets the requirements. By touching the texture of the umbrella surface, the smoothness of the umbrella bone, to ensure that there are no defects that affect the use and aesthetics.

The first thing you can do is to conduct a waterproof performance test. Hold the umbrella open to simulate a rainfall environment with a specified amount of water and water pressure, and observe whether there is any water penetration on the surface of the umbrella. The abrasion resistance test is conducted through a specific friction instrument, rubbing the umbrella surface several times to see whether the surface is hairy and broken. For the strength test of the umbrella bone, professional mechanical testing equipment is used to gradually increase the load, record the value when the umbrella bone breaks, and determine whether it meets the standard. Function test is mainly for the opening and closing performance of the umbrella. For manual umbrellas, check whether the opening and closing process is smooth, whether the umbrella bone can be completely open and locked; automatic umbrellas in addition to testing the sensitivity of the opening and closing, but also to check whether the spring resilience is normal, whether the button is durable. At the same time, simulate the actual use of the scene, test the stability of the umbrella in different angles of opening and closing.
