Description

Labor insurance glove and manufacturing process thereof

Technical field

The invention relates to a labor protection glove, in particular to a structure of a labor protection glove and a manufacturing process thereof.

Background technique

Gloves are a common protective item that can be worn to protect the hands. Gloves can have different classification methods depending on different criteria. According to the material can be divided into cotton gloves, wool gloves, silk gloves, chemical fiber gloves and composite gloves, etc.; according to the style can be divided into long, short, single and finger gloves, etc.; according to the use can be divided into welding Gloves, welding gloves, ceremonial gloves, ski gloves, aerospace gloves, guard gloves, protective gloves, protective gloves, work gloves and boxing gloves, etc.; according to the function can be divided into high temperature gloves, warm gloves, acid and alkali gloves, oil resistant gloves , non-slip gloves, welding gloves and flame retardant gloves, etc.

The hand is one of the most delicate and dense organs in the human body. It consists of 27 bones, which accounts for 1/4 of the total number of human bones, and the distribution and organization of muscles, blood vessels and nerves are extremely surprisingly complex. Only the length of the capillary per square centimeter on the fingertip can reach several meters. There are thousands of ends. These fine neural networks allow us to perceive cold, heat, pain, etc. in a few microseconds, and even feel the vibrations that are as small as the hairline. From the day of the birth of the person, the hand has not stopped the activity, and by the end of life, the hand can move an average of 250 million times. However, we often overlook the importance of the hand and neglect the proper protection of it, so that hand injury accidents account for 20% of all types of work-related accidents.

In modern production operations, first-line production workers who operate many equipment such as rock drills, pneumatic picks, pneumatic drills, logging saws, and impact drills are prone to finger damage, arm fatigue and muscles due to the vibration of strong earthquakes for a long time. Symptoms such as soreness, long-term under such working conditions, it is easy to cause muscle or bone injury, suffering from occupational diseases, so we must try our best to improve the working conditions of workers, wear professional labor protection gloves to relieve muscle tension and fatigue, reduce injuries probability.

At present, there are many gloves for impact resistance. In a utility model patent with the application number 201420238981.9, an impact resistant glove is mentioned, the outer surface of the front surface of the glove is provided with a protective layer, and the inner surface of the front surface of the glove Anti-impact pad, anti-impact pad for sponge impact pad, sponge impact There are 2 pads, and 2 sponge impact pads are respectively located at the joint of the palm and the palm and the finger; the outer surface of the back of the glove is provided with a protective pad, the protective pad is a quadrilateral rubber protective pad, and the quadrilateral rubber protective pad includes several Quadrilateral ribs, a plurality of quadrangular ribs are located at the upper middle portion of the quadrilateral rubber protective pad; the outer surface of the back of the glove is further provided with five protective strips, five protective strips respectively located at five finger positions, and the protective strip includes a dry protective convex Blocks, the ends of the protective bumps are protective ribs. However, the sponge impact resistant pad of the protective glove is relatively insensitive to the impact.

In another utility model patent application number 201220130933.9, a shock-proof, heat-resistant, cut-resistant and wear-resistant glove is mentioned, which has a layer of rolled, uneven film on the palm surface. The film is provided with a plurality of convex bodies connected to each other; the convex body is filled with a sponge-like air hole; the convex body is in the form of a block or a knot.
