Description

Technical Field

[0001] The utility model relates to the field of low-temperature tanks, in particular to a novel impact test low-temperature tank. Background Art

[0002] Impact test low temperature tank is a special test equipment that provides a low temperature environment for samples.

[0003] In the existing impact test cryogenic tank, when taking out the sample from the cryogenic tank, a clamping forceps is usually used to extend into the interior of the cryogenic tank. It is very easy for the sample to fall during the clamping process. If the sample falls into the cryogenic tank, the cryogenic medium will be sputtered, which is very likely to cause harm to the test personnel; if the sample falls outside the cryogenic tank and is bumped, the internal structure of the sample will be damaged, affecting the accuracy of the test results. Utility Model Content

[0004] The utility model aims to provide a novel low-temperature tank for impact testing, which can avoid the phenomenon that the sample is easily dropped when the sample is clamped by clamping pliers.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A novel low-temperature tank for impact testing comprises a shell, a processing chamber, a refrigeration unit, an "n"-shaped base, a tray, a connecting column and a lifting rod; the processing chamber is arranged at the upper end of the shell; the refrigeration unit is fixedly connected to the shell on one side of the processing chamber, and the temperature in the processing chamber is lowered by the refrigeration unit; the upper cover of the processing chamber is provided with a slot cover; the base is fixed to the bottom surface of the processing chamber; the tray is located at the upper end of the base; the upper end of the connecting column is fixedly connected to the tray, and the lower end of the connecting column is passed through the cross bar part of the base, and the lateral swing of the tray when it moves up and down is limited by the connecting column; a lifting rod for lifting the tray is provided on the shell on one side of the processing chamber; the lower end of the lifting rod is connected to the tray, and a protrusion is provided on the lifting rod at the upper end of the shell, and the lifting rod is hung on the upper end of the shell by the protrusion.

[0007] Furthermore, the lifting rod is in an "L" shape, the lateral end of the lifting rod is located at the lower end of the tray, and the longitudinal end of the lifting rod is arranged on the outer surface of the shell.

[0008] Furthermore, a jacket is provided at the longitudinal end of the pulling rod.

[0009] Furthermore, the tray is provided with filter holes through it, and when the tray rises, the low-temperature medium on the tray is discharged downward through the filter holes.

[0010] Furthermore, a control panel is provided on the shell; the control panel is electrically connected to the refrigeration unit, and the refrigeration efficiency of the refrigeration unit is adjusted through the control panel.

[0011] Furthermore, support plates are fixed to the four corners of the upper end of the side wall of the processing chamber, and the slot cover is arranged on the processing chamber through the support plates.

[0012] Furthermore, a handle is provided on the slot cover.

[0013] After adopting the above technical solution, the utility model has the following beneficial effects:

[0014] 1. The utility model adopts a combined design of a base, a tray, a connecting column and an "L"-shaped lifting rod. By lifting the lifting rod upward, the lateral part of the lifting rod acts on the bottom of the tray, driving the tray to rise; the tray moves upward smoothly under the interaction of the connecting column and the base, thereby realizing the smooth lifting and lowering of the sample, so that there is no need to use clamping pliers to extend into the low-temperature tank during sampling, avoiding the phenomenon of sample falling during the clamping process, thereby protecting the test personnel from the sputtering of the low-temperature medium, ensuring the integrity of the sample, and improving the safety and accuracy of the test; at the same time, a jacket is provided at the longitudinal end, which effectively slows down the heat exchange between the outside and the low-temperature environment when standing still, and maintains the stability of the temperature inside the processing chamber.

[0015] 2. The utility model adjusts the refrigeration efficiency of the refrigeration unit through the control panel, thereby achieving precise control of the temperature in the processing room, which is crucial for impact tests that require strict temperature control conditions and ensures the accuracy and repeatability of the test results.

[0016] 3. The utility model provides filter holes on the tray. When the tray is raised, the low-temperature medium on the tray can be discharged downward smoothly, so that a large amount of low-temperature medium is prevented from remaining on the tray when sampling. When sampling, wear protective gloves to directly take the sample or take the sample and the tray together.

[0017] 4. Support plates are fixed at the four corners of the upper end of the side wall of the processing chamber of the utility model, and the slot cover is supported by the support plates so that the slot cover can be stably embedded in the processing chamber, thereby enhancing the sealing of the slot cover, reducing the loss of cold, and improving the energy efficiency and long-term stability of the entire low-temperature slot; the handle on the slot cover facilitates the opening and closing operation.
