Description

Technical Field

[0001] The invention relates to a gas explosion test, in particular to a gas explosion test device. Background Art

[0002] A gas burst tester is a device used to test the gas pressure burst and air pressure resistance of products. The gas burst tester uses gas as the test medium and generates high pressure by continuously compressing the gas medium, which acts on the test product. During the test, key data such as the product's burst pressure and burst shape can be observed and recorded. The gas burst tester is widely used in various product fields that require testing of gas pressure burst and air pressure resistance, such as fire extinguisher cylinders, natural gas cylinders, etc., to test their ability to withstand high-pressure gas. Other products: such as automotive high-frequency cavities, gas shock absorbers, airbags, etc., also require gas burst tests to test their performance.

[0003] When testing containers such as gas cylinders, existing gas explosion testing machines usually place the gas cylinders directly inside the device, and cannot adaptively limit the device. As a result, gas cylinders are prone to offset during the test, affecting the accuracy of the test data. At the same time, the entire device is also prone to offset during the test and cannot be properly fixed, which also affects the accuracy of the test data.

[0004] Combining the above problems, we will find that it is difficult to avoid the above problems at the same time when using the existing gas explosion test devices on the market, and even if they can be solved, they need to be solved with the help of external tools, which makes it impossible to achieve the desired effect.

By setting the positioning block 3010, it is convenient to fix the flip frame 3005. By setting the sixth spring 3008, it is convenient to reset the flip frame 3005.

[0049] The specific implementation of this embodiment is as follows: the positioning frame 3001 can be fixed in a specified position through the cooperation of the mounting block 3003 and the mounting hole 3004. When a blasting test is required, the test device can be moved into the positioning frame 3001. After the container is placed to drive the insertion rod 2218 to be inserted into the insertion hole 3002, the insertion rod 2218 will continue to move, squeezing the flip frame 3005, causing the bottoms of the flip frames 3005 on both sides to flip to opposite sides, and the tops of the flip frames 3005 on both sides to flip to the middle. The flip frames 3005 drive the limit blocks 3006 to be stuck in the limit shell 3007, which can further improve the stability of the entire test device, avoid displacement of the test device, and ensure the test accuracy.
