In the current routine operation process, a crucible tongs is used to clamp the heated crucible from the electric furnace and then transfer it to a tray. However, when the crucible is carbonized on the electric furnace and clamped with a crucible tongs, it is easy for the crucible to become unstable and tip over, and the multiple transportation of the crucible also increases the probability of tipping, thereby causing sample loss.

[0038] like Figure 1 As shown, an embodiment of the utility model provides a retractable high temperature resistant pallet, which comprises: a pallet body 1 and at least one support column 2. The pallet body 1 comprises at least one through hole 11 penetrating the pallet body 1, the through hole 11 is used to place a container to be heated, and the diameter of the through hole 11 is smaller than the maximum diameter of the container. The support column 2 is used to support the pallet body 1, and the length of the support column 2 is retractable.
[0039] It is not difficult to deduce from the above content that when using a retractable high temperature resistant tray to heat the crucible, first, each crucible is inserted from the upper surface of the tray body 1 into at least one through hole 11 provided on the tray body 1. At this time, when the tray body 1 is moved, the crucible provided on the tray body 1 can move together with the tray body 1. Avoid moving each crucible separately in the process of carbonizing the internal sample through the crucible. It also reduces the risk of the crucible falling and tipping due to the inability of the crucible tongs to fully clamp the crucible during the process of moving the crucible separately. The support column 2 can support the tray body 1. When the sample in the crucible is carbonized, multiple support columns 2 can directly contact the electric furnace and lift the tray body 1 to avoid direct contact between the tray body 1 and the electric furnace. At the same time, through the support of the support column 2, the tray body 1 can always obtain a vertical upward support force. With the electric furnace in the process of baking the crucible, the tray body 1 is in a static state for a long time. With the support of the support column 2, the tray body 1 is prevented from sliding and directly contacting the heating wire of the electric furnace, thereby ensuring the safety of the use of the tray body 1. In some embodiments, the support column 2 is made of high temperature resistant material. Since part of the support column 2 may come into direct contact with the heating wire of the electric furnace due to the placement angle during use, the support column 2 made of high temperature resistant material can avoid damage during use. Specifically, tungsten, molybdenum, tantalum, niobium and other materials can be selected as the manufacturing material of the support column 2. Such materials are resistant to high temperatures to prevent the support column 2 from being affected by the high temperature of the electric furnace during long-term use. The specific material is not limited here, and it can meet the manufacturing and high temperature resistance requirements of the support column 2.
[0040] Furthermore, the diameter of the through hole is smaller than the maximum diameter of the crucible.
[0041] It is not difficult to infer from the above content that when the crucible is placed in the through hole 11, the outer surface of the crucible can contact the through hole 11. In this state, the crucible can be inserted into the through hole 11 to prevent the crucible from directly passing through the through hole 11 when placed and failing to interact with the tray body 1. In some embodiments, the diameter of the through hole 11 is the same as the outer diameter of the middle part of the crucible in the vertical direction. When the crucible is placed in the through hole 11, the crucible can be smoothly inserted into the through hole 11, and the contact part between the crucible and the through hole 11 is the middle part. The upper surface of the crucible on the tray body 1 retains sufficient volume, so that the crucible can be smoothly grabbed after the experiment is completed, so that the crucible can be separated from the tray body 1. Similarly, in this state, the portion of the crucible exposed from the lower surface of the tray body 1 also retains sufficient volume and height. Since the bottom of the crucible needs to be in direct contact with the electric furnace during heating, when the length of the crucible exposed from the lower surface of the tray body 1 is sufficient, the lower surface of the tray body 1 and the electric furnace are also kept at a sufficient distance, thereby reducing the impact of the heating of the tray body 1 on the electric furnace and extending the service life of the tray body 1. At the same time, in some other embodiments, such as Figure 5 The diameter of the through hole 11 can be set to different sizes. By matching the sizes of the through holes 11 with crucibles of different diameters, the adaptability and versatility of the tray body 1 can be improved.
[0042] like Figure 1 , Figure 2 , Figure 5 As shown, in some embodiments of the present invention, the retractable high temperature resistant tray comprises: a plurality of elastic buffer rings 111. The plurality of elastic buffer rings 111 are respectively arranged on one side of the through hole 11 for placing the container to be heated.
[0043] It is not difficult to deduce from the above content that when the crucible is placed in at least one through hole 11 of the through hole, the outer surface of the crucible contacts with the elastic buffer ring 111 to avoid direct contact with the hole opening of at least one through hole 11 of the through hole. Since the outer surface of the crucible and the hole opening of at least one through hole 11 of the through hole are both hard materials, when the crucible is in direct contact with at least one through hole 11 of the through hole, it is a hard contact. Long-term use will cause wear of the outer wall of the crucible and wear of the hole opening of at least one through hole 11 of the through hole, causing damage and consumption of experimental equipment. The elastic buffer ring 111 can play a role of buffering protection to avoid wear of the crucible and the hole opening of at least one through hole 11 of the through hole. At the same time, the hole opening after the elastic buffer ring 111 is set, and its diameter is reduced compared to when it is not set. Therefore, when the crucible is placed, the elastic buffer ring 111 will undergo a slight elastic deformation to expand, thereby achieving adaptation with the outer surface of the crucible. At this time, the crucible after placement will be subject to the retraction force from the elastic buffer ring 111, so that the stability of the crucible after placement is further improved. In some embodiments, the elastic buffer ring 111 can be made of high temperature resistant elastic materials such as phenyl silicone rubber, polyimide, etc. There is no limitation on the specific material selection, as long as it can meet the requirements of elasticity and high temperature resistance.
[0044] In addition, if Figure 1 , Figure 2 , Figure 5 As shown, in some embodiments of the present invention, at least one mark 4 is provided on the tray body 1 to mark the position of the through hole 11. .
[0045] It is not difficult to infer from the above content that, since the appearance of the crucibles is very similar, multiple crucibles will be heated simultaneously during the experiment. As the experiment proceeds, the corresponding samples stored in the crucible may be forgotten. The multiple crucibles placed on the tray body 1 can be distinguished by the mark 4, and the mark 4 set on the tray body 1 always remains fixed, which can clearly reflect the crucible corresponding to each mark 4. Compared with the traditional method of writing numbers on the surface of the crucible with a marker, the mark 4 marked on the tray body 1 will not melt with long-term heating, and when the crucible needs to be moved, the crucible and the tray body 1 move together. The mark 4 on the tray body 1 can always remain corresponding to the crucible to avoid confusion. It provides a guarantee for the accuracy of the sample in the crucible during the experiment, avoids errors in the experimental results due to confusion of samples, and ensures the normal progress of the experiment. Figure 5 , Figure 2 As shown in some embodiments, multiple marks 4 are integrally formed with the tray body 1. Since the overall structure of the tray body 1 is relatively thin, when the mark 4 needs to be fixed to the tray body 1, bonding is often used. The bonding glue may melt during the heating process, resulting in the separation of the mark 4 from the tray body 1, which in turn affects the distinction of the sample in the crucible. Therefore, when the mark 4 is integrally formed with the tray body 1, the numerical label on the tray body 1 will not separate from the tray body 1 as the experiment proceeds, so that the mark 4 can always correspond to the crucible, avoiding the inability to distinguish the sample in the crucible and ensuring the experimental results. In some embodiments, the mark 4 integrally formed with the tray body 1 extends a predetermined distance from the upper surface of the tray body 1 in the direction toward the inside of the tray body 1 to form a concave mark 4. When the concave mark 4 is used, the manufacturing material of the tray body 1 can be saved, and the concave mark 4 can also avoid wear during use, thereby causing the mark 4 to wear away and ensure the normal use of the tray body 1. Of course, in other embodiments, the mark 4 integrally formed with the tray body 1 extends a predetermined distance from the upper surface of the tray body 1 in a direction away from the tray body 1. At this time, the mark 4 protrudes upward relative to the upper surface of the tray body 1, which is beneficial for the user to observe the mark 4 more intuitively, thereby finding the crucible corresponding to the mark 4 and determining the items in the crucible.
[0046] In addition, if Figure 1 , Figure 3 , Figure 4 As shown, in some embodiments of the present invention, the retractable high temperature resistant pallet further includes: at least one limiting through hole 3. The limiting through hole 3 is arranged on the lower surface of the pallet body 1 and is configured to allow an external clamp to pass through it to move the pallet body 1.
[0047] It is not difficult to infer from the above content that after the carbonization of the sample in the crucible is completed, it is necessary to realize the overall movement of all crucibles by moving the tray body 1. When the crucible tongs are used to directly clamp the tray body 1, the clamping end of the crucible tongs is small, and multiple crucibles will be placed on the tray body 1 at the same time. Therefore, when the tray body 1 is clamped by the crucible tongs, the tray body 1 may be unstable and other problems. As a result, the tray body 1 will fall over as a whole, resulting in sample loss. The limiting through hole 3 provided on the tray body 1 enables the crucible tongs to extend into the through hole, so that the clamping part of the crucible tongs can also fully contact the tray body 1 and the limiting through hole 3. The contact area between the crucible tongs and the limiting through hole 3 is increased, and at the same time, with the help of the limiting through hole 3, the external force of the crucible tongs is changed from clamping to lifting when the tray body 1 is moved, and the lifting requires much less friction than clamping. Furthermore, since the limiting through hole 3 is provided on the tray body 1, the positional relationship between the limiting through hole 3 and the tray body 1 always remains fixed, so that when the crucible tongs penetrate the limiting through hole 3 and apply the external force required to move the tray to the tray body 1, the point of application of the external force always remains unchanged. By fixing the force point of the tray body 1, it is ensured that each time the crucible tongs are used to move the tray body 1, the tray body 1 will not become unbalanced and fall over due to the change in the direction of the external force. Furthermore, as Figure 4 In some embodiments, the number of the limiting through holes 3 is two, and the two limiting through holes 3 are arranged in parallel; wherein the distance between the two limiting through holes 3 is less than or equal to the distance between the two clamping ends after the crucible tongs are opened. Since the crucible tongs have two clamping ends, and when the crucible tongs are unfolded, the clamping part of the crucible tongs can be opened to form a triangle. The two ends of the opened crucible tongs can be respectively extended into two different limiting through holes 3. At this time, the bottom of the tray body 1 can be subjected to external forces from different limiting through holes 3, and when the interval between the two limiting through holes 3 is larger, the distance from the limiting through hole 3 to the center line of the tray body 1 is also longer. At this time, the length of the force arm of the limiting through hole 3 relative to the center line, then the influence of the external force of the limiting through hole 3 on the tipping of the tray body 1 is reduced accordingly. Further, when the number of the limiting through holes 3 is two, the external force on the bottom of the tray body 1 is also increased to two, and the setting accuracy requirement is reduced compared to the tray body 1 having only one limiting through hole 3. When there is one limiting through hole 3, the limiting through hole 3 needs to be arranged on the center line of the tray body 1 to ensure that when the crucible tongs apply external force, the force can keep the tray body 1 balanced. When there are two limiting through holes 3, since some of the force components can offset each other, the installation accuracy requirements for the limiting through holes 3 are reduced, which can improve the manufacturing efficiency of the tray and reduce the manufacturing difficulty.
[0048] like Figure 1 , Figure 3 , Figure 4As shown, in some embodiments of the present invention, the support column 2 includes: a first rod 21 and a second rod 22, wherein the first rod 21 and the second rod 22 are nested with each other and slide relative to each other.
[0049] It is not difficult to infer from the above content that the nested arrangement of the first rod 21 and the second rod 22 can achieve the change of the length of the support column 2 by telescoping the first rod 21 and the second rod 22, and the change of the length of the support column 2 can achieve the change of the distance between the tray body 1 and the electric furnace. Since different crucibles have different lengths, the volume and length exposed at the bottom of the tray body 1 are also different. Therefore, in order to ensure that the tray body 1 can effectively carry the crucible, the bottom of the crucible is in direct contact with the electric furnace during the experiment. The telescoping of the first rod 21 and the second rod 22 realizes the adjustment of the height of the tray body 1, so as to match with crucibles of different sizes, thereby improving the versatility of the tray.
[0050] Furthermore, in some embodiments, Figure 3 , Figure 4 As shown, the second rod 22 is sleeved outside the first rod 21, and the first rod 21 is provided with a plurality of limit posts 211 at intervals along the length direction. The limit posts 211 are perpendicular to the axis of the first rod 21 and can be pressed and rebounded along the direction perpendicular to the axis of the first rod 21. The second rod 22 is provided with a plurality of limit holes at intervals along the length direction; wherein the limit posts 211 match the limit holes and are inserted into the limit holes.
[0051] It is not difficult to infer from the above content that by setting the limit column 211 that can be pressed and rebounded on the first rod 21 and clamping it into the limit hole on the second rod 22, an external force that interacts with each other is generated between the first rod 21 and the second rod 22, so that the first rod 21 and the second rod 22 cannot perform telescopic movement. When an external force is applied to squeeze the limit column 211 out of the limit hole, since there is no longer an interactive force application point between the first rod 21 and the second rod 22, the first rod 21 and the second rod 22 can resume telescopic movement. After multiple limit columns 211 are provided, different length gears of the support legs can be adjusted by inserting different limit columns 211 to adapt to more types of crucibles. The number of limit holes can be set to only one, or multiple. When the number of limiting holes is 1, to release the static state between the first rod 21 and the second rod 22, only one limiting column 211 needs to be squeezed to contact the force point between the first rod 21 and the second rod 22, thereby realizing the relative sliding between the first rod 21 and the second rod 22. When multiple limiting holes are provided, the limiting columns 211 in multiple limiting holes need to be squeezed at the same time. Such a structure can provide more force points for the interaction between the first rod 21 and the second rod 22, thereby better maintaining the telescopic state of the first rod 21 and the second rod 22. However, it is inconvenient to squeeze the limiting columns 211 in multiple limiting holes at the same time. Therefore, in some embodiments, Figure 1 , Figure 3 , Figure 4 As shown, the support column 2 further includes an unlocking ring 23, which is sleeved on the outside of the second rod 22, and slides along the second rod 22 to press and push the limiting column 211 out of the limiting hole. When unlocking is required, the unlocking ring 23 is pushed to slide along the outer wall of the second rod 22, and the unlocking ring 23 is slid to the limiting hole of the second rod 22, and the unlocking ring 23 can cover each limiting hole, so that each limiting column 211 inserted into the limiting hole is squeezed out of the limiting hole, so as to achieve quick unlocking, reduce the difficulty of changing the length of the support column 2, and improve work efficiency.

It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention.
