Description

Technical Field

[0001] This utility model relates to the field of sample holding technology, specifically a sample holding device for carbon black performance testing. Background Technology

[0002] When storing carbon black samples, testing laboratories select appropriate containers and methods based on the characteristics of the carbon black samples and the needs of subsequent testing. Carbon black typically has a high surface area and a certain degree of hygroscopicity. Therefore, containers with good sealing performance are required during storage to prevent carbon black dust from escaping and causing environmental pollution or cross-contamination. Furthermore, it should be stored in a dry environment to prevent moisture absorption from altering the sample properties.

[0003] Currently, most test samples are placed in plastic bags on the table, which does not form an effective sample management system. If they are placed in a heat preservation cabinet, the temperature inside and outside will exchange when the cabinet door is opened, which will cause a sudden change in the temperature inside the heat preservation cabinet and thus affect the storage of the samples. Therefore, a sample holding device for carbon black performance testing is proposed. Utility Model Content

[0027] Cabinet 1, with a cabinet door 2 rotatably installed at the front end of cabinet 1, and an air conditioning indoor unit 3 and a constant humidity machine 4 installed on one side of the interior of cabinet 1;

[0028] Turntable 5 is located at the lower interior of cabinet 1 and is fixed to cabinet 1;

[0029] A column frame 6 is set at the upper end of the turntable 5 and is rotatably connected to the turntable 5. The column frame 6 has nine cavities 7 inside. The nine cavities 7 are arranged in three layers inside the column frame 6, and three cavities 7 are evenly distributed in each layer of the column frame 6. The front end of the cabinet door 2 has three equally distributed pull-out shells 8 inside. The height of the three pull-out shells 8 corresponds to the height of each layer of cavity 7.

[0030] The stainless steel insulated door panel 12 is located at the front end of the pull-out shell 8, and the stainless steel insulated door panel 12 is rotatably connected to the pull-out shell 8.

[0031] Please see Figure 1 and Figure 2 A magnetic strip 11 is provided inside the stainless steel insulated door panel 12 at the front end of the pull-out shell 8, and the magnetic strip 11 is fixed to the pull-out shell 8. A handle frame 13 is fixed to the outside of the stainless steel insulated door panel 12, and the magnetic strip 11 attracts the stainless steel insulated door panel 12 by magnetic force.

[0032] Please see Figure 2The pull-out shell 8 is located inside the cabinet 1 and has limit strips 10 on both sides. The limit strips 10 are fixed to the pull-out shell 8 and prevent the pull-out shell 8 from being pulled out of the cabinet door 2.

[0033] Please see Figure 2 Sealing strips 9 are provided on both sides of the inner rear end of the pull-out shell 8 near the column frame 6, and the sealing strips 9 are fixed to the pull-out shell 8. The sealing strips 9 improve the sealing performance when the rear end of the pull-out shell 8 is in contact with the column frame 6.

[0034] Please see Figure 2 , Figure 3 and Figure 4 The lower end of the column frame 6 has three evenly distributed inner holes 15 along the ring. A return spring 16 is installed inside the inner hole 15, which enables the limit ball 17 to automatically return to its original position.

[0035] Please see Figure 2 , Figure 3 and Figure 4 The lower end of the return spring 16 is provided with a limit ball 17, and the limit ball 17 is fixed to the return spring 16. The upper end of the turntable 5 is provided with three equally spaced limit holes 14, and the limit ball 17 is adapted to the limit hole 14.
