There is a movable ring plate in between, the movable ring plate is provided with a second ventilation groove, the movable ring plate is provided with a wedge block, the inner ring plate and the outer ring plate are connected with a connecting plate, and a return spring is connected between the connecting plate and the wedge block , The low temperature test box and the high temperature test box are equipped with a boss, the boss is equipped with a top block, and the top of the outer box is equipped with a lifting mechanism.

Description

Technical field [0001] The present invention belongs to the technical field of temperature test equipment, and specific to a two-box high and low temperature impact test chamber. Background technique [0002] As an important detection device, the temperature impact test chamber is mainly used for the safety performance test of electronic components and provides a reliability test, product screening test, etc., temperature impact test chamber test can effectively improve the reliability of the product and The product is effective quality control; with the product quality requirements continue to increase, the temperature impact test chamber is widely used in the technical fields of aviation, automobiles, home appliances. [0003] The existing temperature impact test chamber includes two boxes of temperature impact test chambers and three-box temperature impact test chamber; where two boxes of temperature impact test chambers include low temperature casings that provide a low tempe...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a two-box type high and low temperature impact test box to solve the problem of the low temperature test box and the high temperature test box when the hanging basket passes through the interval platform between the low temperature test box and the high temperature test box during the lifting process. The temperature will be connected through the ventilation groove of the hanging basket, so that the high temperature and low temperature will be connected together, which will greatly increase the temperature in the low temperature test chamber and reduce the temperature in the high temperature test chamber, so that the low temperature test chamber can maintain the cooling and cooling of the set temperature. The high temperature test chamber needs to consume more energy to maintain the temperature rise of the set temperature, and the problem of high operating cost
