Temperature impact test box

Abstract

The invention relates to the field of detection equipment. The invention discloses a temperature impact test box, which comprises a test box body, wherein a high-temperature box body, a low-temperature box body and a test basket are arranged in the test box body; a power box body is connected outside the test box body; a control system, a refrigerating system and a heating system are arranged in the power box body; a lifting device is arranged between the high-temperature box body and the low-temperature box body; an interlayer is arranged between the high-temperature box body and the low-temperature box body for separation; a through hole is formed in the interlayer; and the lifting device is arranged on the inner side wall of the through hole. The lifting device comprises a power guide assembly; the power guide assembly comprises a plurality of guide rails vertically arranged on one side face of the test basket; toothed bars are arranged on the guide rails; a driving shaft is horizontally arranged on the side wall of the through hole; a plurality of gears are fixedly arranged on the driving shaft in a sleeving mode; the gears are meshed with the toothed bars; and the driving shaft is connected with driving equipment. The temperature impact test box provided by the invention has the advantages of stable and rapid rising and falling of the lifting basket, good temperature isolation between the high-temperature box body and the low-temperature box body, and no temperature interpenetration in the lifting process.

Description

technical field [0001] The invention relates to the field of detection equipment, in particular to a temperature shock test chamber. Background technique [0002] The high and low temperature impact test chamber can be used to test the degree to which materials or composite materials can withstand the continuous environment of extremely high temperature and extremely low temperature in an instant, and to test the chemical changes or physical damage caused by thermal expansion and contraction in the shortest time. Its test objects can also be electronic and electrical components, automation components, communication components, electronic chips, auto parts, PCB substrates, metals, chemical materials, polymer materials, plastics, etc. High and low temperature impact test chambers are widely used in defense industry, aviation and household appliances industry and other fields. [0003] In the prior art, there are many types and styles of high and low temperature impact test ch...
