Two-box type impact testing box

Abstract

The invention discloses a two-box type impact testing box. A hanging basket between a high-temperature box and a low-temperature box is moved to transfer a test sample and a room-temperature box does not need to be arranged, so that the defrosting time can be shortened, the consumption of electric quantity is reduced and the testing cost is saved; inner walls of the high-temperature box and the low-temperature box are respectively provided with a heating device and a refrigerating device; the circulation of air flow is driven by an impeller; the air flow rapidly and circularly flows to realize the effect of rapidly heating the test sample or refrigerating the test sample; an impeller, one heating device, an evaporator, a regenerator and the like are all located on the side wall of the high-temperature box or the low-temperature box; a motor drives the impeller to rotate to drive the air flow to flow in the front and rear direction of the box body; the air flow can rapidly flow and the distribution of the air flow is uniform so as to reduce the formation of frost and realize a long-time defrosting-operation-free circulating continuous test; a driving device for moving the hanging basket is arranged in a refrigerator cabinet rather than in the low-temperature box, so as to avoid influences on the driving device by the low temperature and rapidly move the hanging basket; the safety is high.

Description

technical field [0001] The invention belongs to the technical field of test equipment, and relates to a two-compartment impact test box. Background technique [0002] The impact test chamber is the necessary testing equipment for metal, plastic, rubber, electronics and other material industries. It is used to test the material structure or composite material. Internal detection of chemical changes or physical damage caused by thermal expansion and contraction of the sample. [0003] At present, the commonly used impact test equipment in China is a three-box type, including a test area, a high temperature area and a low temperature area. When performing high temperature impact, the two dampers above the high temperature area are opened, and a high temperature air circulation is formed between the high temperature area and the test area to achieve the purpose of high temperature impact; after the high temperature impact is completed, the two dampers in the high temperature ar...
