When the operator lifts or puts down the graphite crucible, the reset spring can absorb part of the impact force, avoiding the direct collision between the insertion rod and the inner wall of the crucible body, thereby reducing the abrasion and damage risk of the crucible body. For some graphite crucibles with brittle material or thin wall thickness, this buffering protection mechanism is particularly important.

By transmitting the stress to the entire hole groove surrounding area through the connecting expansion block, the stress concentration phenomenon is avoided, and the crucible is prevented from being broken due to uneven stress. Moreover, the V-shaped handle can be easily removed when the crucible is heated, without affecting the daily use of the graphite crucible. BRIEF DESCRIPTION OF DRAWINGS

[0029] Reference Figures 1-6 A graphite crucible for graphitization furnace, comprising
[0030] The V-shaped handle 6 is connected with the insertion rod 5 at both sides of the lower end.
[0031] The V-shaped handle 6 is connected with the insertion rod 5 at both sides of the lower end.
[0032] The reserved hole groove 2 is arranged at both sides of the upper end of the inner wall of the crucible body 1, and the insertion rod 5 can be inserted into both sides of the upper end of the inner wall of the crucible body 1 through the reserved hole groove 2.
[0033] The reserved hole groove 2 arranged at both sides of the upper end of the inner wall of the crucible body 1 is provided with the reset spring 3, one side of the reset spring 3 is connected with the crucible body 1, and the side of the reset spring 3 away from the crucible body 1 is connected with the connecting expansion block 4.
[0034] The inner wall of the crucible body 1 provided with the reserved hole groove 2 is connected with one side of the reset spring 3, and the reset spring 3 and the connecting expansion block 4 are both horizontally arranged in the reserved hole groove 2.
[0035] After the insertion rod 5 is inserted into the reserved hole groove 2, a firm connection structure is formed between the insertion rod 5 and the crucible body 1, the position of the insertion rod 5 is further fixed under the limitation of the reserved hole groove 2, the V-shaped handle 6 cannot swing or tilt at will in the use process, which not only improves the stability of the handle itself, but also enhances the structural stability of the entire graphite crucible, when the graphite crucible is lifted or moved, the stable handle can better bear the weight of the crucible body 1 and the internal materials, reduces the risk of tilting or overturning of the crucible body 1 caused by unbalanced gravity, and protects the safety of the equipment and the operator.
[0036] The connecting telescopic block 4 is cylindrical, and its cross-section is circular.
[0037] The reserved slots 2 on both sides of the upper end of the inner wall of the crucible body 1 are circular slots, and the radius of the circular cross-section of the connecting telescopic block 4 is equal to the radius of the circular slot 2.
[0038] The inner side of the V-shaped handle 6 is narrower at the top and wider at the bottom, forming a V shape.
[0039] During the use of the V-shaped handle 6, the sliding of the connecting telescopic block 4 in the reserved slot 2 and the buffering effect of the return spring 3 effectively reduce the rigid collision between the handle and the crucible body 1. When the operator lifts or puts down the graphite crucible, the return spring 3 can absorb part of the impact force, preventing the insertion rod 5 from directly colliding violently with the inner wall of the crucible body 1, thereby reducing the wear and damage risk of the crucible body 1. For some graphite crucibles with brittle materials or thin walls, this buffering protection mechanism is particularly important, which can effectively extend the service life of the crucible body 1 and reduce the replacement frequency and operating costs of the equipment.
[0040] An observation window 8 is inlaid inside one side of the crucible body 1.
[0041] The four sides of the observation window plate 8 are embedded inside one side of the crucible body 1, and the four sides of the crucible body 1 and the observation window plate 8 are provided with embedded grooves 7.
[0042] An observation window 8 is embedded inside one side of the crucible 1, allowing operators to clearly observe the internal conditions of the crucible 1, such as the melting state and reaction status of the materials. This is crucial for experiments or production activities that require real-time monitoring of the internal processes, enabling operators to understand and control the dynamic changes within the crucible 1 in a timely manner.
[0043] During use, when not in use, the return spring 3 is in its naturally extended state. Under the elastic force of the return spring 3, the connecting telescopic block 4 is positioned in a specific position within the pre-drilled slot 2. At this time, the outer surface of the connecting telescopic block 4 is flush with the inner wall of the crucible body 1. When it is necessary to use the V-shaped handle 6 to lift the graphite crucible, the operator holds the V-shaped handle 6 and presses it inward, aligning the insertion rods 5 on both sides of the lower end of the V-shaped handle 6 with the pre-drilled slots 2 on both sides of the crucible body 1. The operator then releases the V-shaped handle 6, and the insertion rods 5 on both sides of the lower end of the V-shaped handle 6 are inserted into the pre-drilled slots 2. At the same time, the connecting telescopic block 4 compresses the return spring 3. The embedded groove 7 inside the crucible 1 makes the connection between the crucible 1 and the observation window plate 8 more secure. When the crucible 1 is subjected to external forces, such as vibrations or impacts during movement, lifting or placement, the embedded groove 7 can play a role in stress dispersion. It will evenly transfer the external force acting on the observation window plate 8 to the surrounding structure of the crucible 1, reducing the risk of the observation window plate 8 breaking or the crucible 1 deforming due to local stress concentration. Operators can observe the inside of the crucible 1 from multiple angles through the observation window plate 8 to ensure effective monitoring of the entire inside of the crucible 1.
