Problems solved by technology

The lifting and lowering of the sample rack is detected by installing a travel switch on the control track of the motor. The disadvantage of the long-term use of the travel switch often occurs, and the cabinet will be deformed when it is serious.
In addition, the lifting time of the sample rack is 5-8 seconds. During this process, there will be temperature interpenetration between the high temperature zone and the low temperature zone, which will cause serious impacts when the temperature changes suddenly.
[0003] The control instruments in the temperature shock box have the disadvantages of cumbersome operation, complicated operation, and low control accuracy, which have brought a lot of inconvenience to customers in terms of test accuracy and use.

Embodiment Construction

[0022] Below in conjunction with accompanying drawing, the present invention will be further described as follows:

[0023] As shown in the drawings, the present invention includes a box body 6, an electrical cabinet 7, an electrical system 19, a refrigeration system, and a heating system. One side of the box body is connected to the electrical cabinet, and a control panel 8 is provided on the front of the electrical cabinet. The control panel is provided with a touch screen, the electrical system is arranged on the rear side of the control panel, and the interior of the box is divided into a high temperature zone 5, a test zone 11 and a low temperature zone 2 from top to bottom, and the test zone is connected with the high temperature zone, Pneumatic doors are provided between the low-temperature areas, and the pneumatic doors are connected to cylinders. The high-temperature area is equipped with a heating system and a temperature-resistant circulating fan. The low-temperature...

Abstract

The invention relates to a three-box type temperature impact test box, which comprises a box body, an electrical cabinet, an electrical system, a refrigerating system and a heating system, wherein the interior of the box body is divided into a high temperature area, a test area and a low temperature area from the top to the bottom, pneumatic doors are arranged between the test area and the high temperature area and between the test area and the low temperature area, the pneumatic doors are connected with air cylinders, the heating system and a temperature resisting circulation fan are arranged in the high temperature area, the refrigerating system and a temperature resisting circulation fan are arranged in the low temperature area, and temperature resisting circulation fans are respectively arranged in a high temperature box body and a low temperature box body. The three-box type temperature impact test box disclosed by the invention has a novel structure and is convenient to use, a three-box type temperature impact and control process is adopted to completely overcome the defect of temperature interpenetration, the action speed of the pneumatic doors is high, and the switching process of the high temperature area and the low temperature area can be completed within 3 seconds. The travel switch fault caused by conventional motor pullup and the defect of pull deformation of thebox body are avoided, the temperature in the box body is uniform and stable, and the working efficiency is greatly improved.

Description

[technical field] [0001] The invention relates to the technical field of sample temperature shock test instruments, in particular to a three-box temperature shock test chamber. [Background technique] [0002] At present, the common temperature shock test chambers are two-chamber structure, which is divided into high temperature zone and low temperature zone. The switch of the experimental area is by pulling the sample holder from the low temperature area to the high temperature area in the entire box, and then lowering it from the high temperature area to the low temperature area, repeatedly performing high temperature and low temperature shocks. The lifting and lowering of the sample rack is detected by the travel switch installed on the control track of the motor. The disadvantage of the long-term use of the travel switch often occurs, and the cabinet will be deformed in severe cases. In addition, the lifting time of the sample rack is 5-8 seconds. During this process, th...
