Substance-fetching plate device used for high-low temperature box

Abstract

The invention relates to a substance-fetching plate device used for a high-low temperature box. The substance-fetching plate device comprises a box body (1), wherein the position of the opening of the box body (1) is rotatably connected with a box door (2), and is in fit connection with a heat-insulating plate (3); a seal ring (4) is arranged between the transparent heat-insulating plate (3) and the opening of the box body (1); and the heat-insulating plate (3) is provided with substance-fetching openings (5); each substance-fetching opening is in fit connection with a heat-preserving and heat-insulating soft sheet (6); and each heat-preserving and heat-insulating soft sheet is provided with cutting notches (7) used for fetching a substance. The substance-fetching plate device has the following advantages: during product replacement for the device, the box door is opened, and a product is fetched out and placed from the position of the cutting notches of a heat-preserving and heat-insulating soft sheet, so the testing environment of the interior of the high-low temperature box can be guaranteed from being damaged, and the testing results of the product are effectively guaranteed.

Description

technical field [0001] The invention relates to a test device for electronic products, in particular to a pick-up board device for a high-low temperature box. Background technique [0002] In industries such as electrical engineering, electronics, and instrumentation, it is necessary to carry out adaptability tests on the parts of the product during storage, transportation, and use in high, low, and humid environments to determine the temperature resistance adaptability of the above products to high, low, and humid environments. , especially the changes in the electrical and mechanical properties of the product, it is necessary to use a high and low temperature box during the test. The high and low temperature box can simulate the test conditions of different environments such as high temperature and low temperature. Many products need to be tested under constant temperature conditions. However, the existing high and low temperature boxes have the following disadvantages in ...

[0002] In industries such as electrical engineering, electronics, and instrumentation, it is necessary to carry out adaptability tests on the parts of the product during storage, transportation, and use in high, low, and humid environments to determine the temperature resistance adaptability of the above products to high, low, and humid environments. , especially the changes in the electrical and mechanical properties of the product, it is necessary to use a high and low temperature box during the test. The high and low temperature box can simulate the test conditions of different environments such as high temperature and low temperature. Many products need to be tested under constant temperature conditions. However, the existing high and low temperature boxes have the following disadvantages in use: when one product is tested and another product is replaced, the temperature inside the box changes greatly when the door of the high and low temperature box is opened and closed, and at the same time Water vapor in the air will also enter the box, changing the test environment in the box and seriously affecting the test structure
