Description

Technical Field

[0001] This utility model belongs to the field of sampling device technology, and more specifically, it relates to a rapid sampling device for high and low temperature experiments. Background Technology

[0002] During high and low temperature experiments, it is necessary to take samples regularly to test their performance. The samples need to avoid drastic temperature fluctuations. Therefore, the samples need to be taken from the experimental chamber to the transition chamber using an electric push rod and a negative pressure suction cup. After the experimental chamber gate is closed, the samples are transferred from the transition chamber to the sampling chamber. After the transition chamber gate is closed, the staff can open the sampling chamber to take out the samples, thus reducing temperature fluctuations in the experimental chamber during the sampling process.

[0003] Based on the above, when removing samples from the sampling chamber, staff need to open the chamber door and use tools to remove the samples, which is inconvenient and time-consuming. This results in the samples being exposed to room temperature for an extended period, affecting the accuracy of the test results. Utility Model Content

This simplifies the sampling process, shortens sampling time, reduces the duration of sample exposure to ambient temperature, minimizes the possibility of temperature fluctuations, and ensures the accuracy of test results.

Detailed Implementation

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. Example 1

[0021] As attached Figure 1 To be continued Figure 6 As shown: This utility model provides a rapid sample collection device for high and low temperature experiments, including a high and low temperature experimental chamber 1, a sealed door 2, a guide support frame 3, a sealing structure, a sample storage tray 4, a sample storage box 5, and an insulation sleeve 6. Multiple sealed doors 2 are evenly distributed and hinged to the front of the high and low temperature experimental chamber 1. An experimental chamber is located on the left side of the high and low temperature experimental chamber 1, a transition chamber is located in the middle of the high and low temperature experimental chamber 1, and a sampling chamber is located on the right side of the high and low temperature experimental chamber 1. The guide support frame 3 is slidably connected to the right side of the high and low temperature experimental chamber 1. The sealing structure is located in the middle of the high and low temperature experimental chamber 1. The sample storage tray 4 is fixedly connected to the upper part of the guide support frame 3. The sample storage box 5 is placed on top of the sample storage tray 4. The insulation sleeve 6 is located on top of the sample storage box 5.

[0022] The sealing structure includes a sealing gate 101 and a positioning electric push rod 102. Two sealing gates 101 are provided, each sliding vertically on the left and right sides of the high-low temperature test chamber 1. Multiple positioning electric push rods 102 are evenly distributed and bolted to the left and right sides of the high-low temperature test chamber 1. The piston rods of the multiple positioning electric push rods 102 pass through the high-low temperature test chamber 1 and are fixedly connected to the two sealing gates 101. A drive motor is bolted to the middle of the high-low temperature test chamber 1. The output shaft of the drive motor passes through the high-low temperature test chamber 1 and is fixedly connected to a positioning box. An electric push rod is bolted to the lower part of the positioning box, and a negative pressure suction nozzle is fixedly connected to the end of the piston rod of the electric push rod.

[0023] The specific usage and function of this embodiment are as follows: When conducting high and low temperature experiments on materials, the temperatures of the experimental chamber, transition chamber, and sampling chamber are all controlled within a suitable range by a temperature control system. First, the material is placed in the experimental chamber of the high and low temperature experimental chamber 1. After being placed in a high or low temperature environment for a period of time, the positioning electric push rod 102 on the left side drives the sealing gate 101 on the left side to rise. At this time, the electric push rod moves to drive the negative pressure suction nozzle to take the sample into the transition chamber. Then, the positioning electric push rod 102 on the left side pushes the sealing gate 101 on the left side to reset. The drive motor drives the positioning box and the electric push rod to rotate, causing the electric push rod to change direction. The positioning electric push rod 102 on the right side drives the sealing gate 101 on the right side to rise. The electric push rod sends the sample into the sampling chamber and places the sample in the sample storage box 5. Then, the electric push rod returns to its original position, and the positioning electric push rod 102 on the right side pushes the sealing gate 101 on the right side to close. At this time, the sealing chamber door 2 on the right side can be opened to take out the sample. Example 2

[0024] As attached Figure 4 To be continued Figure 7 As shown: Based on Example 1, a thermal insulation structure is also included; the thermal insulation structure is located on the right side of the high and low temperature test chamber 1.

[0025] The insulation structure includes a guide mounting cylinder 103 and a guide mounting frame 106; the guide mounting frame 106 is slidably connected to the right side of the high and low temperature test chamber 1; the guide mounting cylinder 103 is fixedly connected to the left side of the guide mounting frame 106.

[0026] The insulation structure also includes a limiting electric push rod 104 and a first positioning magnet 105; the limiting electric push rod 104 is bolted to the upper part of the guide mounting cylinder 103; the piston rod of the limiting electric push rod 104 passes through the guide mounting cylinder 103 and is fixedly connected to the first positioning magnet 105.

[0027] The insulation structure also includes a limiting connecting rod 301 and a second positioning magnet 501; the rear end of the limiting connecting rod 301 is hinged to the middle of the guide support frame 3, and the front end of the limiting connecting rod 301 is hinged to the middle of the right sealing door 2; the second positioning magnet 501 is fixedly connected to the inside of the sample storage box 5.

[0028] The insulation structure also includes a third positioning magnet 601 and a fourth positioning magnet 602; the third positioning magnet 601 is fixedly connected to the lower part of the insulation sleeve 6; the fourth positioning magnet 602 is fixedly connected to the upper part of the insulation sleeve 6, and multiple negative pressure suction holes are provided in the middle of the sample storage tray 4.

[0029] The specific usage and function of this embodiment: The insulation sleeve 6 is attracted to the lower part of the piston rod of the limiting electric push rod 104 by the first positioning magnet 105 and the fourth positioning magnet 602. After the sample is placed in the sample storage box 5, the limiting electric push rod 104 pushes the insulation sleeve 6 downward, so that the insulation sleeve 6 is attracted to the upper part of the sample storage box 5 by the third positioning magnet 601 and the second positioning magnet 501. When the right-side sealing door 2 is opened, the sealing door 2 will pull the limiting connecting rod 301, so that the limiting connecting rod 301 drives the guide support frame 3 to slide forward. At this time, the guide mounting cylinder 103 and the guide mounting frame 106 are limited by the piston rod of the limiting electric push rod 104 and will move forward with the insulation sleeve 6 and the guide support frame 3, so that the sample storage box 5 and the insulation sleeve 6 are moved out of the sampling chamber. At this time, the negative pressure suction hole no longer attracts the sample storage. The sample storage box 5 is placed in a box to facilitate sample retrieval by staff. Staff can directly overcome the attraction of the first positioning magnet 105 and the fourth positioning magnet 602 to remove the sample storage box 5 and the insulation sleeve 6 simultaneously. When testing the sample, the insulation sleeve 6 can be opened by directly overcoming the attraction between the third positioning magnet 601 and the second positioning magnet 501. After the test is completed, the sample storage box 5 and the insulation sleeve 6 are re-adsorbed together and placed above the sample temporary storage tray 4. At this time, the negative pressure suction hole re-adsorbs the sample storage box 5, and the first positioning magnet 105 and the fourth positioning magnet 602 are re-adsorbed together. After the sealed door 2 is closed, the limit connecting rod 301 will push the guide support frame 3 to return, and the limit electric push rod 104 will pull the insulation sleeve 6 upward to raise the insulation sleeve 6, making it easier to place the next sample on the sample storage box 5.
