Technical Field

[0001] The utility model relates to the technical field of ozone testing equipment, in particular to an ozone aging testing box. Background Art

[0002] The content of ozone in the atmosphere is very small, but it is the main factor for rubber cracking. The ozone aging chamber simulates and strengthens the ozone conditions in the atmosphere, studies the effect of ozone on rubber, and quickly identifies and evaluates the method of rubber anti-ozone aging performance and anti-ozonant protection efficiency, and then takes effective anti-aging measures to improve the service life of rubber products; According to the Chinese patent authorization announcement number CN 210322601 U, an ozone aging test chamber is disclosed, including a base, a body is fixedly installed on the top of the base, a test cavity is opened inside the body, a first pneumatic cylinder is fixedly installed on the top of the inner cavity of the test cavity, and side rods are fixedly installed on both sides of the first pneumatic cylinder. The ozone aging test chamber is provided with a first pneumatic cylinder, a driving motor, a driving gear and a driven gear. The operation of the first pneumatic cylinder will drive the two fixed fixtures to move in opposite directions, thereby realizing a tensile test on the rubber product. The operation of the driving motor will cause the rotating shaft to drive the driven gear and the rotating rod to rotate through the driving gear, and then through the cooperation between the two fixed fixtures, a torsion test on the rubber product will be realized, thereby improving the testing function of the ozone aging test chamber, and thus increasing the practicality of the ozone aging test chamber.

[0003] In this application, when fixing the rubber product, four round buttons need to be manually rotated so that four clamping blocks can complete the fixation of the rubber product. This fixing method is relatively cumbersome and laborious, and reduces the detection efficiency. Utility Model Content
