TECHNICAL FIELD

[0001] The utility model relates to wear resistance test technical field especially relates to a wear resistance testing device for inflatable raft fabric. BACKGROUND

[0002] The life raft is a lifesaving equipment developed in the 1960s, which is made of rubber, and is folded and placed in a glass steel container at ordinary times. The shape of the container is usually a cylinder with hemispherical ends. When an emergency occurs, the life raft is automatically inflated by pulling the valve of the self-carried gas cylinder (usually CO2 gas) to form a shape, and the inflated life raft has a certain buoyancy and space to realize the carrying of the people in distress and the people falling into the water, and achieves the lifesaving purpose. When the inflatable raft is produced, the fabric needs to be tested for wear resistance.

[0003] At present, when testing the wear resistance of the fabric, clamping tools are used to fix the two sides of the fabric. However, when another piece of fabric needs to be tested after the test is completed, the bolts and other parts on the clamping tool need to be disassembled. After clamping the new fabric, the bolts and other parts need to be installed again, which slows down the testing speed of the fabric. During the wear resistance test of the fabric, the friction between the wear-resistant block and the fabric will cause a lot of lint to fly, which will easily be inhaled into the lungs of the personnel, causing damage to the body of the workers. Therefore, a wear resistance testing device for inflatable raft fabric is proposed to solve the above problems. UTILITY MODEL CONTENTS
