AI Technical Summary
Technical Problem
The sealing strips of the high and low temperature cycle test chamber are prone to loosening and wear during use, resulting in poor sealing effect and affecting the accuracy and repeatability of the test.
Method used
The magnetic seal strip fits tightly with the edge seal strip and is reinforced by the compression strip and guide column structure. The guide hole and telescopic spring are used to ensure that the seal strip does not rub when opening and closing the door, thereby extending its service life.
Benefits of technology
It improves the sealing effect, reduces temperature loss, enhances the accuracy and repeatability of test data, and extends the service life of the sealing strip.

Abstract
The utility model discloses high and low temperature cycle test box equipment, and relates to the technical field of test equipment, the high and low temperature cycle test box equipment comprises a test box body, a box door and a working chamber, the test box body is hinged to the box door, and the working chamber is arranged in the test box body; in order to avoid abrasion of the magnetic sealing strip due to the fact that the magnetic sealing strip is plugged into a reserved gap groove when the test box door is frequently opened and closed, the magnetic sealing strip is located on a circle of the edge sealing strip, the magnetic sealing strip is tightly attached to the edge sealing strip, the edge sealing strip reinforces the magnetic sealing strip, meanwhile, the loss of temperature from the interior of the test box body can be reduced, and the service life of the test box is prolonged. The error between the temperature in the working cavity and the set temperature is reduced, so that experimental data are more accurate, the sealing effect is improved when the pressing strip is attached to or loosened from the magnetic sealing strip and the magnetic sealing strip is attached to the pressing strip, and friction of the contact surface between the magnetic sealing strip and the edge sealing strip can be avoided when the pressing strip approaches the magnetic sealing strip back and forth. And the service life of the magnetic sealing strip is longer.
