Description

Technical Field

[0001] This utility model belongs to the technical field of salt spray testing machines, and in particular relates to a bracket for bolt salt spray testing. Background Technology

[0002] Salt spray testing machines use salt spray corrosion to test the reliability of samples. It's one type of artificial environmental protection system, and many companies use salt spray testing machines to simulate the destructive effects of marine climates on their products. Salt spray corrosion testing is one of the most common artificial environmental protection tests. Existing bolt salt spray tests using fixed support frames require repeated runs to complete the test, resulting in long testing times and high costs.

[0003] Chinese utility model patent CN102854123A discloses a universal fixture for salt spray testing of bolt parts. This fixture offers a simple structure, convenient sample clamping, high positioning accuracy, and the ability to simultaneously test multiple specifications of samples. It boasts good versatility, accurate test data, and high testing efficiency. It solves the technical problems of existing fixtures, such as complex structures, the ability to test only samples of the same specification at a time, poor versatility, and limited sample storage capacity, leading to low testing efficiency and high testing costs. The fixture includes a housing with several sample fixing plates horizontally arranged between opposite side walls. Each sample fixing plate includes an upper clamping plate and a lower clamping plate elastically connected to the lower end of the upper clamping plate. Several upper clamping openings are provided at the lower end of the upper clamping plate, and lower clamping openings corresponding to the upper clamping openings are provided at the upper end of the lower clamping plate. The angle between the axis of the inscribed circle of the upper and lower clamping openings and the bottom surface of the housing is 20° to 40°. However, the device also has some other problems. For example, when using the device, because the bolt sample is small, the placement method generally results in a large contact area with the horizontal plane, causing some parts to remain immersed in the salt water, which has a significant impact on the test results.
