Description

Technical Field

[0001] The utility model relates to the field of testing machines, in particular to a bag oscillation testing machine. Background Art

[0002] The luggage oscillation tester is used to test the impact resistance of luggage, mainly to test the tensile properties of various luggage, and can complete mechanical performance tests such as tension, compression, and bending. The test method is usually: fix the clamp at the bottom of the luggage, fix the stretching mechanism at the top of the luggage, and directly apply pressure to the luggage to stretch the luggage, thereby testing the luggage.

[0003] At present, the fixing of bags is usually clamped by the clamp provided by the testing machine. The sides of the bags need to be aligned with the multiple clamps of the clamp respectively. However, different types of bags have different shapes and sizes, and the existing clamps provided by the clamp are usually fixed on the testing machine. The clamp includes a bottom plate and another clamp fixed on the bottom plate, and the bottom of the clamp is fixed to the testing machine by fasteners such as screws. A gap is formed between the two clamps. When in use, the bags are directly fitted with the clamps. This fixed simple clamp can only be adapted to a certain type of bags. In this way, a new clamp must be made for each type of bags, which not only increases investment and cost, is not economical, but also wastes resources. Bags of different sizes cannot be clamped. When the size of the bags is relatively small, the clamps of this clamp cannot fit tightly with the outer wall of the bags, resulting in unstable clamping. During the test, the bags are easily separated from the clamp. When the size of the bags is relatively large, the clamps of this clamp cannot be adapted due to the size, and need to be disassembled and replaced separately, which is very troublesome.
