Description

Technical Field

[0001] The utility model relates to the technical field of crucible racks, and particularly relates to a pull-out muffle furnace crucible support. Background Technique

[0002] The muffle furnace crucible support is a key accessory for high-temperature experiments, usually made of high-temperature-resistant materials, capable of withstanding extreme temperatures above 1000°C. Its design structure is stable, ensuring that the crucible remains horizontal during heating, avoiding sample tilting or spilling. The support usually has a porous or grid-like design, facilitating uniform heat distribution and allowing gas circulation to improve heating efficiency. It is a standardized component of laboratory high-temperature equipment. Traditional crucible supports are mostly fixed structures, generally with only 6 or 8 hole positions. When an additional 2 to 4 crucibles need to be heated, an additional crucible support needs to be set up, occupying more internal space of the muffle furnace. Content of the Utility Model

[0003] The purpose of the utility model is to provide a pull-out muffle furnace crucible support to solve the problem in the above background technique that traditional crucible supports are mostly fixed structures, generally with only 6 or 8 hole positions. When an additional 2 to 4 crucibles need to be heated, an additional crucible support needs to be set up, occupying more internal space of the muffle furnace.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A pull-out muffle furnace crucible support, including a main limiting frame, with main support frames arranged on the front and rear sides of the main limiting frame. The main support frames are in an inverted concave-shaped structure. Below the main limiting frame and inside the main support frames, there is a sliding limiting frame. On the front and rear sides of the sliding limiting frame, there are sliding support frames. The sliding support frames are in a square-shaped structure with a hole in the middle. On both inner sides of the main limiting frame and the sliding limiting frame, there are limiting rings. At positions corresponding to the limiting rings inside the main support frames and the sliding support frames, there are support rods. Below the front and rear sides of the main support frames, there are sliding rods. On one side of the front and outer surfaces of the sliding limiting frame, there are sliding sleeves that are slidably connected to the sliding rods.

[0005] Preferably, both the main limiting frame and the sliding limiting frame are in a structure similar to the Chinese character "丰" (丰), and the limiting rings are arranged between the crossbeams of the "丰"-shaped structures of the main limiting frame and the sliding limiting frame. On one side of both the main limiting frame and the sliding limiting frame, there are hooks.

[0006] Preferably, inside one side of the main support frame away from the sliding sleeve, there are limiting double rods. The support rods arranged on the sliding limiting frame are slidably connected to the limiting double rods. The limiting double rods are respectively arranged above and below the support rods.

[0007] It should be noted that in the translation of the structure description in item

[16] , the description of "回字形结构" in the original text is not very clear. I translated it as "square-shaped structure with a hole in the middle" according to the general understanding. If there is a more accurate description, it can be adjusted accordingly.Preferably, both the main support frame and the sliding support frame are provided with support beams on their left and right sides, and the support rod is fixedly connected to the support beams.

[0008] Preferably, a process seam is provided between the limiting ring disposed inside the main limiting frame and the main support frame.

[0009] Compared with the prior art, the beneficial effects of this utility model are: a sliding crucible support is slidably set inside the traditional fixed crucible support; based on the traditional setting of 6 holes, 6 sliding crucible supports that can be pulled out are set; when 2 to 4 additional crucibles need to be heated, the sliding crucible supports can be pulled out according to the required number of crucible holes, thus meeting the crucible support requirements while reducing the internal space occupied by the muffle furnace.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-5, the utility model provides a draw - type muffle furnace crucible support, which includes a main limit frame 1. The front and rear sides of the main limit frame 1 are provided with main support frames 2. The main support frames 2 are in an inverted concave - shaped structure. Below the main limit frame 1 and inside the main support frames 2, there is a sliding limit frame 3. The front and rear sides of the sliding limit frame 3 are provided with sliding support frames 4. The sliding support frames 4 are in a square - frame - like structure with a hole in the middle. On both inner sides of the main limit frame 1 and the sliding limit frame 3, there are limit rings 5. At positions corresponding to the limit rings 5 inside the main support frames 2 and the sliding support frames 4, there are support rods 6. Below the front and rear sides of the main support frames 2, there are sliding rods 7. On the front and outer surfaces of one side of the sliding limit frame 3, there is a sliding sleeve 8 which is slidably connected to the sliding rods 7.

[0018] During use, the main limit frame 1 is supported and fixed by the main support frames 2. Limit rings 5 are set on the main limit frame 1, and support rods 6 are set at positions corresponding to the limit rings 5 inside the main support frames 2. The crucible to be heated is placed at the position of the limit rings 5, and the crucible is supported by the support rods 6. At this time, the limit rings 5 on the main limit frame 1 and the limit rings 5 on the sliding limit frame 3 are overlapped, which will not interfere with the placement of the crucible. When it is necessary to expand the placement holes of the crucible, pull the sliding support frame 4. Through the sliding connection between the sliding sleeve 8 and the sliding rods 7, the displacement of the sliding support frame 4 is limited. The sliding support frame 4 is used to drive the sliding limit frame 3 to move away from the main support frame 2. When the expanded crucible holes meet the requirements, stop pulling and ensure that the limit rings 5 on the main limit frame 1 and the limit rings 5 on the sliding limit frame 3 are overlapped. Then place the crucible to be heated at the position of the expanded limit rings 5, and support the crucible by the support rods 6.

[0019] Both the main limit frame 1 and the sliding limit frame 3 are in a structure like the Chinese character 'feng' (丰). The limit rings 5 are set between the cross - beams of the 'feng' - shaped structures of the main limit frame 1 and the sliding limit frame 3. On one side of both the main limit frame 1 and the sliding limit frame 3, there are hooks 9. Through the 'feng' - shaped main limit frame 1 and sliding limit frame 3, the connection strength between the limit rings 5 and the main limit frame 1 and the sliding limit frame 3 is ensured. By setting hooks 9 on one side of the main limit frame 1 and the sliding limit frame 3, the sliding support frame 4 can be moved by pulling the hooks 9.

[0020] Inside one side of the main support frame 2 far from the sliding sleeve 8, there are limit double - rods 10. The support rods 6 set on the sliding limit frame 3 are slidably connected to the limit double - rods 10. The limit double - rods 10 are respectively arranged above and below the support rods 6. The support rods 6 set on the sliding limit frame 3 are clamped by the limit double - rods 10, so as to limit the movement of the sliding support frame 4.

[0021] Both the main support frame 2 and the sliding support frame 4 are provided with support beams 11 on the left and right sides. The support rod 6 is fixedly connected to the support beams 11, and the support rod 6 is fixedly installed inside the main support mining machine 2 and the sliding support frame 4 through the support beams 11.

[0022] The limiting ring 5 inside the main limiting frame 1 is provided with a process seam 12 between it and the main support frame 2, which provides space for the installation and sliding of the sliding support frame 4.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
