Description

Technical Field

[0001] This utility model relates to the field of muffle furnace crucible rack technology, and more specifically, to a porous muffle furnace crucible rack. Background Technology

[0002] A muffle furnace is a device used for high-temperature heating. The crucible is used to hold or heat samples, reagents, and other substances. A muffle furnace crucible rack is a device used to support the crucible and is commonly used in laboratory operations of muffle furnaces.

[0003] Currently, the tongs and pots placed in commonly used muffle furnace tongs and pots racks are all of fixed size, which may not be able to position tongs and pots that are outside the size range, thus narrowing the scope of application. In addition, some tongs and pots racks need to be assembled every time they are used, which causes inconvenience. For example, a multi-hole type high safety performance muffle furnace crucible rack disclosed in CN221527296U includes: multiple legs and a support platform. The top of the support platform has multiple recessed slots. The inner surfaces of the multiple legs are fixedly connected to the brackets. The upper surface of the brackets is provided with a tray. The outer surface of the tray is fixedly connected with a protrusion. Crucible tongs holes are opened on both outer surfaces of the support platform.

[0004] As can be seen from the above-disclosed solution, the size of the recessed groove used to fix the tong pot is fixed. Although the size of each recessed groove is different, it cannot be used to position tong pots that exceed the size of all recessed grooves, thus narrowing the scope of application. Furthermore, the legs and the support platform need to be combined and disassembled once each time the tong pot enters or leaves the muffle furnace. This disassembly and assembly is not only time-consuming and laborious, but also easily leads to burns to the hands. In addition, the fixed support height of the tong pot rack may not be suitable for muffle furnaces with different internal heights. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a porous muffle furnace crucible rack. This porous muffle furnace crucible rack, through the setting of sliding grooves, limiting grooves, and sliders, allows the support plate to slide inside the support frame, thereby freely combining the size of the tong pot placement hole, increasing the applicability of the tong pot rack. Furthermore, through the setting of adjusting rods, first connecting columns, second connecting columns, and positioning tubes, it is not only convenient to adjust the support height of the tong pot rack as needed, but also convenient to enter and exit the muffle furnace together with the tong pot, without the need for disassembly and assembly inside the muffle furnace, thus improving the convenience of use.

[0008] Furthermore, the horizontal adjustment mechanism includes several support plates, with sliders fixedly connected to both ends of the support plates. A screw is threadedly connected to the surface of the slider, and a manual knob is fixedly connected to one end of the screw. One end of the manual knob contacts and presses against the surface of the support frame. The horizontal movement position of the support plate can be manually and quickly adjusted by using the manual knob and the screw.

[0009] Furthermore, the inner surface of the support frame is provided with a sliding groove, the inner wall of which is slidably connected to the surface of the slider, and the surface of the support frame is provided with a limiting groove that communicates with the sliding groove, the inner wall of which is slidably connected to the surface of the screw, so that the screw can slide with the slider.

[0010] Furthermore, the height adjustment mechanism includes four adjustment rods, one end of which has an axially penetrating adjustment hole, and the surface of the adjustment rod is fixedly connected with annularly distributed anti-slip strips, which can prevent the hand from slipping on the surface of the adjustment rod.

[0011] Furthermore, the inner wall of the adjustment hole is threaded, one end of the adjustment hole is threaded to the surface of the first connecting post, and the other end of the adjustment hole is threaded to the surface of the second connecting post. The adjustment hole can accommodate and adjust the extension and retraction positions of the first and second connecting posts.

[0012] Furthermore, the side of the support plate has an arc-shaped groove, and two adjacent arc-shaped grooves enclose a tong pot placement hole, so that the tong pot placement hole can be assembled into different sizes according to actual needs.

[0013] Furthermore, both the first and second connecting posts are provided with external threads on their surfaces, and the external threads are in opposite directions, so that when the adjusting rod rotates, the first and second connecting posts can extend and retract synchronously in opposite directions.

[0014] Compared with existing technologies, the advantages of this utility model are: This design incorporates a sliding groove, a limiting groove, and a slider, allowing the support plate to slide inside the support frame. This enables the free combination of different sizes for the tongs / pot placement holes, thus increasing the applicability of the tongs / pot holder.

[0015] This design, through the setting of the adjusting rod, the first connecting column, the second connecting column, and the positioning tube, not only facilitates the adjustment of the support height of the tong pot rack as needed, but also makes it easy to move in and out of the muffle furnace together with the tong pot, eliminating the need for disassembly and assembly inside the muffle furnace, thus improving ease of use.
