Description

Technical Field

[0001] The invention relates to the technical field of glove box protective gloves, in particular to a comfortable glove box protective glove and a design method thereof. Background Art

[0002] In the nuclear industry, workers often need to face work scenarios such as nuclear fuel processing, nuclear waste processing, and nuclear emergency rescue. In order to protect workers from radiation, chemicals, nuclear waste, etc., they often need to wear multi-layer gloves during actual operations. Therefore, protective gloves are generally not worn close to the body, but are usually the last barrier. Wearing multi-layer gloves may indeed affect the flexibility of operation, especially when the protective gloves are not of the right size, such as the glove fingers are too long, the finger circumference is small, or the tiger's mouth is tight, which may cause discomfort and inconvenience in operation. Wearing multi-layer gloves, in particular, the existing glove box protective gloves are not fit: the glove fingers are too long, the finger circumference is small, the tiger's mouth is tight, etc.

[0003] Although existing glove design methods have improved the comfort of gloves to a certain extent, these methods are mostly limited to improving the overall size of the hand and do not involve the design of detailed sizes such as fingers and palms; and the application scenarios of glove models are limited, and the prepared gloves are mostly worn directly against the body, which cannot meet the hand size requirements under multiple protections in the nuclear industry.

[0004] Therefore, it is necessary to redesign the detailed dimensions of the glove box protective glove model so that the gloves made based on this model are more comfortable to wear and fit better, reducing the fatigue of workers when wearing them for a long time. Summary of the invention

[0086] The thickness gradient of the palm portion is set, including: Figure 2 As shown, the palm part is divided into two areas with the palm center as the center, namely, palm area 1 and palm area 2. Palm area 1 is close to the thumb and palm area 2 is close to the little finger.

[0088] A thickness gradient is set for palm area 1 so that the thickness of palm area 1 gradually decreases from the palm edge to the palm center, and a thickness gradient is set for palm area 2 so that the thickness of palm area 2 gradually decreases from the palm center to the palm edge, and the thickness of the entire palm part gradually decreases from palm area 1 to palm area 2.
