Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a muffle furnace crucible support. Background Technology

[0002] In existing technologies, muffle furnaces are used for sample ashing pretreatment. To ensure complete ashing, the temperature is typically set above 500℃, which is quite high. Traditionally, reagents need to be added during the testing process, and different crucible sizes are required for different tests. Crucible tongs are usually used to handle individual crucibles, removing them from and placing them into the muffle furnace. However, the operator needs to apply considerable force to the tongs to ensure stability, which is time-consuming, labor-intensive, and inefficient. Furthermore, the small size of the muffle furnace cavity makes it easy for crucibles to collide with each other due to improper handling with the tongs, causing sample spillage and affecting experimental results. Before ashing, strong acids such as sulfuric acid are added to carbonize the sample before high-temperature ashing in the muffle furnace. After ashing, liquid samples may remain in some cases, posing a risk of injury if spilled.

[0003] Furthermore, the use and maintenance of muffle furnaces mentions that the occurrence of sudden temperature drops in the high-temperature furnace cavity should be reduced. In traditional operations, crucibles are removed and placed one by one with crucible tongs, which is complicated and inefficient. This increases the time the furnace cavity is open and the time the high-temperature furnace cavity is exposed to room temperature, thus increasing the frequency and duration of sudden temperature drops in the furnace cavity. This affects the service life of the muffle furnace and may even lead to damage or scrapping of the muffle furnace equipment. Utility Model Content

[0037] like Figures 1 to 8 As shown, a muffle furnace crucible support according to this embodiment includes a main board 100, a secondary board 200, and a support assembly 300. The main board 100 is provided with at least one row of placement slots 110 for placing crucibles. All placement slots 110 in the row are spaced apart along a first direction. The main board 100 is provided with two sets of first adjustment holes 120 spaced apart along the first direction. Multiple first adjustment holes 120 in the two sets of first adjustment holes 120 are spaced apart along a second direction, which is perpendicular to the first direction. The main board 100 is also provided with an insertion hole 130 penetrating the main board 100. The secondary board 200 is provided with two insertion holes 130 spaced apart along the first direction for insertion into the first adjustment holes 120. The first adjusting rod 210 is connected to the sub-plate 200, which includes at least one sub-plate 220. The sub-plate 220 is provided with a plurality of limiting grooves 221 at intervals along the first direction corresponding to the placement groove 110. The limiting grooves 221 are provided one-to-one with the placement groove 110. The support assembly 300 includes an operating member 310 and a support part 320 connected to each other. The main plate 100 has a first side 101 and a second side 102 that are arranged opposite to each other. The support part 320 passes through the insertion hole 130 and abuts against the second side 102. The operating member 310 is located on the side of the first side 101 that is away from the second side 102, and the operating member 310 abuts against the side wall of the first side 101 and / or the insertion hole 130.

[0038] In actual operation, the crucible is placed on the first side 101 of the main board 100. The main board 100 has a rectangular plate structure. A support foot 150 is provided at each of the four corners of the second side 102 of the main board 100 to suspend the main board 100 in the furnace cavity of the muffle furnace.

[0039] In this embodiment, by connecting the sub-plate 200 to the main plate 100, and by connecting the first adjusting rod 210 on the sub-plate 200 to the corresponding first adjusting hole 120, the limiting groove 221 and the placement groove 110 cooperate to form a placement position for placing crucibles. That is, the actual size of the placement position for placing crucibles is adjusted by the limiting groove 221 to accommodate crucibles of different sizes, thereby enabling the handling of crucibles of different sizes. This makes crucible clamping and handling more convenient and faster, allowing for the batch placement or removal of crucibles at once. Furthermore, by having the support component 300 pass through the insertion hole 130 and the support part 320 abut against the second side surface 102 of the main plate 100, and the operating component 310 abut against the first side surface 101 of the main plate 100 and / or the side wall of the insertion hole 130, the combined action of the support part 320 and the operating component 310 enables the entire main plate 100, the sub-plate 200, and the crucibles placed on the main plate 100 to be clamped and transported together, which is convenient and quick.

[0040] In this embodiment, the main board 100 is made of ceramic to ensure sufficient stability under the high-temperature environment inside the muffle furnace. Of course, depending on the actual situation and conditions, a quartz stone or quartz glass main board can also be used, as long as the stability of the main board 100 under high-temperature conditions can be guaranteed. Such designs are all within the protection scope of this utility model. Similarly, the sub-board 200 and the support assembly 300 are also made of high-temperature resistant materials such as ceramic and quartz to ensure their stability under high temperatures.

[0041] In one embodiment, the sub-plate 200 further includes a fixing part 230, which is connected to at least one end of the sub-plate 220 along a first direction. One first adjusting rod 210 is disposed on the fixing part 230, and the other first adjusting rod 210 is disposed on the sub-plate 220. Two limiting rods are respectively connected to two sets of first adjusting holes 120 on the main plate 100, thus ensuring the sub-plate 200 is securely fixed to the main plate 100. Of course, in actual operation, the fixing part 230 and the sub-plate 220 can also be connected by snap-fit ​​connection, plug-in connection, threaded fastening connection, etc., as long as the connection between the fixing part 230 and the sub-plate 220 is secure, thereby ensuring the overall stability of the sub-plate 200 and ensuring its secure connection to the main plate 100, such designs are all within the protection scope of this utility model.

[0042] In one embodiment, the sub-plate 200 includes at least two sub-plates 220, and the multiple sub-plates 220 are all connected to the same fixing part 230 (e.g., Figure 4 (as shown) and / or each sub-board 220 is connected to a fixing part 230 (as shown) Figure 5(As shown). Multiple sub-plates 220 are spaced apart along the second direction, and adjacent sub-plates 220 are movably connected. This allows for individual adjustment of each sub-plate 220 to adjust the placement size of each row of placement slots 110, enabling crucibles of different sizes to be placed simultaneously on the same main plate 100 to suit different testing requirements and scenarios.

[0043] In one embodiment, such as Figure 5 As shown, each sub-plate 220 is connected to a fixing part 230. One fixing part 230 is provided with a second adjustment hole 240 on one side along the second direction, and the adjacent fixing part 230 is provided with a second adjustment rod (not shown in the figure) that is inserted into the second adjustment hole 240. Through the cooperation of the second adjustment rod and the second adjustment hole 240, each sub-plate 220 can be movably and adjustablely connected, making operation simple and convenient.

[0044] Furthermore, such as Figure 6 As shown, each end of the sub-plate 220 along the first direction is connected to a fixing part 230 to ensure a stable connection between the multiple sub-plates 220.

[0045] In one embodiment, the support portion 320 has a support surface 321 facing the second side 102 and an inclined surface 322 facing away from the second side 102. The support surface 321 fits against the second side 102 to ensure the stability of the support portion 320 in supporting the motherboard 100. Furthermore, the inclined surface 322 is set at an angle to the support surface 321, so that when the operator passes the support portion 320 through the socket 130, the side with less thickness passes through the socket 130 first, making it easier for the support portion 320 to pass through the socket 130 and improving operational convenience.

[0046] In one embodiment, such as Figure 7 As shown, the angle between the inclined surface 322 and the support surface 321 is α1, where 5°≤α1≤15°. When the angle between the inclined surface 322 and the support surface 321 is α1<5°, the thickness difference of the overall support part 320 is not significant, which does not achieve the effect of facilitating the passage of the support part 320 through the socket 130. When the angle between the inclined surface 322 and the support surface 321 is α1>15°, the thickness of the front end of the support part 320 is easily too small, affecting the support strength of the support part 320 to the motherboard 100.

[0047] In one embodiment, a positioning block 330 is provided on the support surface 321, and a positioning groove 140 is provided on the second side surface 102 for the positioning block 330 to be inserted and engaged. When the support surface 321 and the second side surface 102 abut and fit together, the positioning block 330 is engaged in the positioning groove 140, so as to realize the quick positioning of the support part 320 and the motherboard 100, and also make the connection between the support part 320 and the motherboard 100 more stable, ensuring the stability during the transportation of the motherboard 100 through the support component 300.

[0048] In one embodiment, the operating member 310 has a connecting portion 340 near one end of the support portion 320. The connecting portion 340 is partially inserted into the insertion hole 130. The operating member 310 is connected to the support portion 320 through the connecting portion 340. The connecting portion 340 and the support portion 320 are arranged at an angle and / or the connecting portion 340 and the operating member 310 are arranged at an angle. Specifically, for example... Figure 7 As shown, the included angle between the connecting part 340 and the supporting part 320 is α2, 95°≤α2≤105° and / or the included angle between the connecting part 340 and the operating member 310 is α3, 95°≤α3≤105°, so that the connecting part 340, the supporting part 320 and the operating member 310 are respectively set at a certain inclined angle, which facilitates insertion into the socket 130.

[0049] In one embodiment, the operating member 310 is provided with a handle 311 at the end away from the support 320. The outer surface of the handle 311 is provided with a protective sleeve 3111. The protective sleeve 3111 is a heat-insulating protective sleeve 3111. The outer side of the protective sleeve 3111 is provided with anti-slip texture. When the operator holds the handle 311 to operate, it will prevent burns and slippage, thus ensuring work safety.

[0050] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
