Description

Technical Field

[0001] The utility model belongs to the technical field of crucible movement, and in particular relates to a crucible moving tool and a crucible. Background Art

[0002] During the firing process of powdered chemicals, the powder needs to be placed in a crucible first, and then the crucible containing the powder is placed in an experimental furnace for firing. After the chemicals are fired, they are taken out of the experimental furnace for subsequent testing and analysis.

[0003] For a smaller crucible, a crucible tongs or tweezers can usually be used to place the crucible at a designated position in the experimental furnace and to take it out smoothly. For example, in the prior art, publication number CN211886919U discloses a crucible tongs, comprising a clamping portion and a handle portion, the clamping portion comprising two clamping arms arranged opposite to each other, one end of the clamping arm being connected to the handle portion, and an opening of a constant size being formed between the two clamping arms to allow the bottom of the crucible to pass through but not the top of the crucible to pass through, thereby solving the problems that the existing crucible tongs cannot deliver the crucible into the end of the furnace, and the pointed mouth portion affects the operation and causes finger fatigue.

[0004] However, when the amount of powder to be fired reaches more than 2 kg, a larger crucible (360*360mm) is needed. As the crucible capacity increases, the weight will also increase significantly. In addition, the experimental furnace is deep and the space is limited. The existing crucible tongs and tweezers cannot pick up the bulky crucible and place it in the deep experimental furnace. After firing is completed, the crucible cannot be removed from the experimental furnace using existing tools. Utility Model Content

[0005] The utility model provides a crucible moving tool and a crucible to solve the technical problem that the existing crucible tongs cannot clamp the heavy crucible and place it in a deep experimental furnace.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] In a first aspect, a crucible moving tool is provided, comprising:

[0008] The clamping member is a closed frame-type structure, and a fastening assembly is provided on the inner wall thereof;

[0009] A connecting component, one end of which is connected to the clamping member and the other end of which is connected to a hand piece;

[0010] The clamping piece is used to be sleeved on the outside of the crucible, so that the fastening assembly is pressed against the outer wall of the crucible to clamp and move the crucible.

[0011] Furthermore, the fastening assembly includes a fastening plate and an elastic member, and a plurality of the fastening plates are provided. The plurality of fastening plates are sequentially spaced apart and arranged on the inner wall of the clamping member, and one elastic member is arranged on each of the fastening plates.

[0012] Furthermore, the elastic member is a spring, and the spring is arranged at the middle part of one end of the fastening plate away from the inner wall of the clamping member.

[0013] Furthermore, the spring and the fastening plate are welded.

[0014] Furthermore, the cross section of the spring is annular.

[0015] Furthermore, the clamping member is a splint, and a plurality of the splints are provided. The plurality of splints are connected end to end in sequence, and the angle between two adjacent splints is a right angle. A connecting sleeve is provided at the bottom of one of the splints, and the connecting assembly is connected to the splint via the connecting sleeve.

[0016] Furthermore, a plurality of the clamping plates connected end to end in sequence form a rectangular cross-section.

[0017] Furthermore, the connecting assembly includes a pull rod, and the pull rod is provided in plurality, and the plurality of pull rods are connected end to end.

[0018] Furthermore, the handpiece is an annular structure, the outer side of the handpiece is wrapped with a heat insulating sleeve, and three connecting rods are provided inside the handpiece, and the ends of the three connecting rods are fixed to the connecting assembly.

[0019] In a second aspect, a crucible is provided, wherein the crucible is transported and moved using the tool as described above.

[0020] Compared with the prior art, the utility model has the following beneficial effects:

[0021] 1. When the crucible is moved and transported, the clamping piece is sleeved on the outside of the crucible, and its frame structure can effectively surround the outside of the crucible to form a stable support and clamping environment, ensuring that the crucible is not easy to slip or tip over during the movement; secondly, when the fastening component is pressed against the outer wall of the crucible, the firmness between the crucible and the clamping piece can be further enhanced, making the clamping of the clamping piece more stable, and the operator can move the crucible to the working position inside the experimental furnace through the cooperation of the handpiece and the connecting component, which solves the technical problem that the existing crucible tongs cannot clamp the heavy crucible and place it in a deep experimental furnace.

[0022] 2. Each fastening plate is provided with an elastic part, which can provide a certain elasticity and clamping force. When the clamping part is set on the outside of the crucible, the elastic part can fit tightly on the outer wall of the crucible, ensuring that the crucible is not easy to slip or shake during movement, thereby ensuring the stability and safety of operation.

[0023] 3. Place the spring in the middle of the end of the fastening plate away from the inner wall of the clamp to ensure that the spring can evenly apply force to all sides when compressed.

[0024] 4. The welding connection has high strength and durability, can withstand greater tension and pressure, and extends the service life of the tool.

[0025] 5. The annular cross-section enables the spring to evenly disperse force when subjected to pressure or tension, reducing stress concentration, helping to maintain the stability of the spring structure and preventing it from deformation or breakage during use.

[0026] 6. Since the clamp is composed of multiple splints, when a splint is damaged or needs to be replaced, it can be removed and replaced separately without replacing the entire clamp, which reduces maintenance costs and difficulty and extends the service life of the tool; secondly, the connecting assembly is connected to the splint through the connecting sleeve, which ensures a firm connection between the clamp and the connecting assembly, and is not prone to loosening or falling off, thereby improving work safety and reliability.

[0027] 7. The rectangular cross-section design enables the clamp to provide a more stable and uniform clamping force when clamping the crucible, and can better resist deformation and distortion when subjected to external forces, ensuring the stability of the crucible during movement.

[0028] 8. Multiple pull rods are connected end to end, so that the length of the connecting assembly can be flexibly adjusted as needed, which can adapt to crucibles of different sizes and operation requirements of different lengths, thereby improving the flexibility and adaptability of the tool.

[0029] 9. The ring-shaped handpiece is ergonomically designed, allowing the operator to comfortably hold and operate the entire crucible moving tool, reducing hand fatigue during long-term operation and improving work efficiency. The heat-insulating sleeve wrapped around the outside of the handpiece can effectively isolate high temperature and protect the operator's hands from burns. It can be safely used to move high-temperature crucibles, reducing operational risks. BRIEF DESCRIPTION OF THE DRAWINGS
